Estimation of corneal endothelial pump function in long-term contact lens wearers. (1/128)

PURPOSE: To study the effects of long-term contact lens wear on morphologic and physiologic properties of corneal endothelial cells. METHODS: The endothelial permeability to fluorescein and the rate of corneal deswelling from hypoxia-induced edema were measured in 20 long-term (mean, 17+/-9 years; range, 5-33 years) contact lens wearers and 20 age-matched control subjects. From these data, the relative endothelial pump rate in each subject was estimated, based on the pump-leak hypothesis of corneal hydration control. Corneal autofluorescence and the aqueous humor flow rate were determined by fluorescein fluorophotometry. Images of corneal endothelial cells were recorded by using specular microscopy, and morphologic indices (cell density, coefficient of variation of cell area, percentage of hexagonal cells, and skewness) were determined. RESULTS: No statistically significant differences were found between the contact lens and control groups in endothelial permeability, corneal deswelling, relative endothelial pump rate ([mean +/- SD] 1.07+/-0.33 relative pump units versus 1.01+/-0.25 relative pump units; contact lens versus control; P = 0.57), and endothelial cell density. Contact lens wearers had a significantly higher aqueous humor flow rate (3.57+/-1.03 microl/min versus 2.77+/-0.51 microl/min; P = 0.005), coefficient of variation of cell area (0.35+/-0.09 versus 0.28+/-0.04; P = 0.006), and corneal autofluorescence (3.1+/-0.6 ng/ml versus 2.3+/-0.3 ng/ml fluorescein equivalents; P < 0.001) than did non-contact lens wearers. CONCLUSIONS: Despite the known effects of long-term contact lens wear on corneal endothelial morphometry, no effect on endothelial function was found.  (+info)

Effects of experimental exposure to triethylamine on vision and the eye. (2/128)

OBJECTIVES: To determine the effect of triethylamine (TEA) on the cornea and to evaluate the cause of blurred vision. To find the lowest observed effect concentration of exposure to TEA. METHODS: Four people were exposed to TEA for 4 hours at concentrations of 40.6, 6.5, and 3.0 mg/m3. Before and after every exposure, symptoms and ocular microscopy findings were recorded. Binocular visual acuity and contrast sensitivity at 2.5% contrast were also measured. Also, before and after the 40.6 mg/m3 exposure, corneal thickness was measured and ocular dimensions were recorded by ultrasonography, endothelial cells of the cornea were analysed, and serum and lacrimal specimens were collected for the analysis of TEA. RESULTS: After exposure to 40.6 mg/m3 TEA there was a marked oedema in the corneal epithelium and subepithelial microcysts. However, corneal thickness increased only minimally because of the epithelial oedema. The lacrimal concentrations of TEA were, on average (range) 41 (18-83) times higher than the serum TEA concentrations. The vision was blurred in all subjects and visual acuity and contrast sensitivity had decreased in three of the four subjects. After exposure to TEA at 6.5 mg/m3 two subjects experienced symptoms, and contrast sensitivity had decreased in three of the four subjects. There were no symptoms or decreases in contrast sensitivity after exposure to a TEA concentration of 3.0 mg/m3. CONCLUSIONS: TEA caused a marked oedema and microcysts in corneal epithelium but only minor increases in corneal thickness. The effects may be mediated by the lacrimal fluid owing to its high TEA concentration. Four hour exposure to a TEA concentration of 3.0 mg/m3 seemed to cause no effects, whereas exposure to 6.5 mg/m3 for the same period caused blurred vision and a decrease in contrast sensitivity.  (+info)

Clinical estimation of corneal endothelial pump function. (3/128)

PURPOSE: To develop a technique to estimate the corneal endothelial pump rate in human subjects. METHODS: Corneal hydration control is thought to be maintained by a pump-leak mechanism whereby the leak of solutes and fluid across the endothelial barrier into the stroma is, in the steady state, exactly balanced by the pumping of solutes and passive fluid transfer across the endothelium to the aqueous humor. Overall corneal hydration control can be measured from the rate at which the swollen cornea thins (deswells), and a measure of the leak can be obtained simultaneously from the endothelial permeability to fluorescein. From the pump-leak hypothesis, the deswelling rate is directly proportional to the pump rate and inversely proportional to the leak rate. The relative endothelial pump rate can be estimated as the product of the normalized deswelling rate and the normalized endothelial permeability. This procedure was used to obtain the relative endothelial pump rate in 41 patients with diabetes mellitus, 12 patients with long-term corneal transplants, 20 long-term wearers of contact lenses, and 19 normal volunteer subjects after the short-term administration of topical dorzolamide. RESULTS: The relative endothelial pump rate did not differ significantly from that of control subjects in diabetics, in contact lens wearers, and after dorzolamide administration, but was markedly decreased in the patients with corneal transplants, despite a reduction in permeability (reduced leak). CONCLUSIONS: This method allows the estimation of both the barrier and pump arms of corneal endothelial function and should be useful in the investigation of causes and mechanisms of functional endothelial insufficiency.  (+info)

Sympathetic swelling response of the control eye to soft lenses in the other eye. (4/128)

PURPOSE: To compare central corneal swelling and light scatter after 8 hours of sleep in eyes wearing high- and low-Dk hydrogel lenses and to the contralateral control eyes. METHODS: Twenty neophyte subjects wore a Lotrafilcon A (Dk, 140; Ciba Vision, Duluth GA) silicone hydrogel lens and an Etafilcon A (Dk, 18; Acuvue; Vistakon, Jacksonville, FL) 58% water content hydrogel lens of similar center thickness in random order in the right eye only, for overnight 8-hour periods. The contralateral nonwearing left eyes served as controls. Central corneal thickness was measured using an optical pachometer and light scatter using a Van den Berg stray-light meter before lens insertion, after lens removal on waking, and every 20 minutes for the next 3 hours. RESULTS: Central corneal swelling induced by the Etafilcon A lens on eye opening was significantly higher than with the Lotrafilcon A lens (8.66%+/-2.84% versus 2.71%+/-1.91%; P<0.00001). Light scatter induced by the Etafilcon A lens on eye opening was significantly higher than with the Lotrafilcon A lens (46.09+/-5.62 versus 42.78+/-6.07 Van den Berg units, P = 0.0078). The swelling of the control eyes paired with the Etafilcon A lens-wearing eyes was also slightly but significantly higher than that of the control eyes paired with the Lotrafilcon A lens-wearing eyes (2.34%+/-1.26% versus 1.44%+/-0.91%; P = 0.0002). Light-scatter measurements were not significantly different between control sets of eyes but showed the same trend. CONCLUSIONS: In neophyte subjects, corneal swelling of the contralateral control eyes appears to be influenced by the swelling of the fellow lens-wearing eyes-that is, the swelling of the contralateral control eye was significantly lower when there was less swelling of the fellow eye wearing the high-Dk lens. Although there was no statistically significant difference in light-scatter measurements between the control sets of eyes, a trend similar to the corneal swelling results was observed, which could be used to support the suggestion that this may be a sympathetic physiological response rather than an unusual sampling coincidence.  (+info)

Acute hydrops in the corneal ectasias: associated factors and outcomes. (5/128)

PURPOSE: To identify factors associated with the development of hydrops and affecting its clinical outcome. METHODS: Chart review of all patients with acute hydrops seen by a referral cornea service during a 2.5-year period between June 1996 and December 1998. RESULTS: Twenty-one patients (22 eyes) with acute hydrops were seen. Nineteen patients had keratoconus, 2 had pellucid marginal degeneration, and 1 had keratoglobus. Twenty-one of 22 (95%) eyes had seasonal allergies and 20 of 22 (91%) eyes had allergy-associated eye-rubbing behavior. Six of 22 (27%) had a diagnosis of Down's syndrome. Six patients were able to identify a traumatic inciting event: vigorous eye rubbing in 4 and traumatic contact lens insertion in 2. The affected area ranged from 7% to 100% of the corneal surface area and was related to disease duration and final visual acuity. Proximity of the area of edema to the corneal limbus ranged from 0 to 2.3 mm and was also related to prognosis. Three serious complications were observed: a leak, an infectious keratitis, and an infectious keratitis and coincidental neovascular glaucoma. Various medical therapies did not differ significantly in their effect on outcome, and ultimately 4 (18%) of 22 patients underwent penetrating keratoplasty. Best-corrected visual acuity was equal to or better than prehydrops visual acuity in 5 of the 6 patients in whom prehydrops visual acuity was known, without corneal transplantation. CONCLUSIONS: Allergy and eye-rubbing appear to be important risk factors in the development of hydrops. Visual results are acceptable in some patients without surgery. Close observation allows for the early detection and treatment of complications such as perforation and infection.  (+info)

Anomalous acute inflammatory response in rabbit corneal stroma. (6/128)

PURPOSE: To investigate the nature and cause of an acute, anomalous stromal edema after epithelial debridement in the rabbit cornea. METHODS: Series I: Adult New Zealand White rabbit corneas were mounted in perfusion chambers. The endothelium was bathed with Ringer's fluid, and the outer surface was covered with silicone oil. The epithelium of one eye was debrided with a scalpel before mounting, and the cornea of the fellow eye was debrided with a rotating brush after stabilization in the perfusion chamber. Using specular microscope tracking software, it was possible to measure total swelling and local swelling within the cornea. Series II: Diclofenac sodium ophthalmic solution 0.1% or a placebo was applied topically, 1 drop per 45 minutes for 3 hours before animals were euthanatized. RESULTS: Series I: Corneas with their epithelium scraped with a scalpel before mounting were 37.5 +/- 17.5 microm (n = 6; P < 0.001) thicker in vitro than the stromas of perfused, intact fellow corneas. Epithelial debridement with a rotating brush after mounting resulted in an immediate (within 8 minutes) stromal swelling that plateaued in 1 hour at 31.0 +/- 5.3 microm (n = 6; P < 0.001). Curiously, in six of six corneas, the anterior stroma swelled more than the posterior stroma. In four of six corneas, the posterior stroma thinned. Analysis showed this pattern to be consistent with a sudden increase in anterior swelling pressure or osmotic pressure and to be inconsistent with a change in endothelial transport properties. Series II: Placebo-treated corneas swelled 30.6 +/- 7.7 microm (n = 5) 1 hour after debridement, whereas corneas pretreated with diclofenac sodium swelled only 19.2 +/- 3.1 microm (n = 6; P < 0.008). CONCLUSIONS: The anterior stromal swelling occurs rapidly and near the site of epithelial injury suggesting messenger and/or enzymatic involvement with an effect parallel to apoptosis. Reduction of the swelling response with nonsteroidal anti-inflammatory drugs (NSAIDs) implicates the cyclooxygenase pathway. The swelling is similar to the unexplained acute edema that occurs during inflammation in the rat paw edema model, and may represent a general mechanism for mobilization of inflammatory cells.  (+info)

Measurement of mRNAs for TGFss and extracellular matrix proteins in corneas of rats after PRK. (7/128)

PURPOSE: To assess the role of the transforming growth factor (TGF)ss system in formation of corneal haze after excimer laser photorefractive keratectomy (PRK), levels of mRNAs for three TGFss isoforms (TGFss1, TGFss2, and TGFss3), the TGFss type II receptor (TssRII), and extracellular matrix (ECM) genes including fibronectin (FN), collagen I, collagen III, and collagen IV were measured in rat corneas. METHODS: Corneas were graded for corneal haze at 0, 1.5, 7, 21, 42, and 91 days after PRK. Total RNA was isolated from pooled corneas, and the levels of mRNAs were measured using competition-based quantitative reverse transcription-polymerase chain reaction (RT-PCR). RESULTS: Severe corneal haze developed by day 42 and persisted to day 91. Levels of TGFss1 mRNA were high in rat corneas before PRK and remained relatively constant. In contrast, levels of TGFss2 and TGFss3 mRNAs were very low in normal corneas, increased 300-fold and 25-fold, respectively, on day 21, and remained elevated on day 91. Levels of mRNA for TssRII increased, with a peak elevation of 50-fold on day 42 after PRK. Levels of mRNAs for ECM proteins also increased. Fibronectin mRNA was nondetectable in normal corneas but rapidly increased to 675 copies/cell on day 7 and remained elevated to day 91. Collagen III mRNA levels peaked on day 21 with a 700-fold increase compared with a very low level of expression in normal cornea, and then decreased on day 91. Expression of collagen I mRNA lagged expression of collagen III mRNA and peaked at day 42 after PRK with a 1200-fold increase over normal cornea. In contrast, mRNA for collagen alpha(1)IV, a major component in basement membranes, remained relatively stable through day 21 and then increased slightly on days 42 and 91. CONCLUSIONS: The synchronized increase in mRNA synthesis for both the TGFss system and key ECM genes supports the hypothesis that TGFss is a key growth factor promoting stromal haze formation in corneas after PRK and suggests that limiting TGFss system may reduce corneal scarring after excimer laser ablation.  (+info)

Blockade of TGF-beta by in vivo gene transfer of a soluble TGF-beta type II receptor in the muscle inhibits corneal opacification, edema and angiogenesis. (8/128)

Accumulating evidence suggests the involvement of TGF-beta in the process of corneal opacity, which is one of the serious causes of visual loss. However, whether TGF-beta is indeed critical for the pathogenesis remains unknown. We constructed an adenovirus expressing an entire ectodomain of the human type II TGF-beta receptor fused to Fc portion of human IgG (AdTbeta-ExR): this soluble receptor is secreted from AdTbeta-ExR-infected cells, binds to TGF-beta and inhibits TGF-beta signaling. When AdTbeta-ExR was injected into the femoral muscle of Balb/c mice, a high level of the soluble receptor protein (2.0-3.5 x 10(3) pM) was detectable in the serum and in the ocular fluid for at least 10 days. In the mice subjected to corneal injury with silver nitrate and to intramuscular injection with either saline or a control adenovirus expressing beta-galactosidase (AdLacZ), corneal opacification composed of extracellular matrix (ECM) accumulation, of infiltration of neutrophils and monocytes/macrophages, and of angiogenesis were all induced. In contrast, they were markedly reduced in the mice injected with AdTbeta-ExR. Immunohistochemical analysis revealed that TGF-beta, fibronectin, macrophage chemoattractant protein-1, and vascular endothelial growth factor were densely stained in the edge of wounded cornea, but they were scarcely present in the injured-cornea of AdTbeta-ExR-treated mice. Our results demonstrate that TGF-beta indeed plays a critical role in the process of cornea opacification, and that adenovirus-mediated expression of a soluble TGF-beta receptor can be therapeutically useful.  (+info)

Most patients undergoing cataract surgery suffer from corneal edema after the surgery which temporarily reduces their visual acuity until corneal edema resolves over several weeks Brimonidine drops are a well known and safe Anti-glaucoma medication, used to lower intra ocular pressure.. there have been several clinical observations that patients receiving Brimonidine drops had a faster resolution of their corneal edema even in the presence of normal intra-ocular pressure.. The investigators postulated that administering topical Brimonidine to patients with significant post operative corneal edema will hasten their recovery and visual improvement.. In order to prove that Brimonidine drops contribute to faster resolution of cornel edema and visual improvement, the study will randomly compare 50 post cataract surgery patients (group A)who will be administered Brimonidine to 2 control groups (50 people in each group):. group B will be given topical timolol drops 0.5% (another well recognized anti ...
Delicate hydration of the corneal stroma is needed to maintain good vision and corneal transparency. In Fuchs Endothelial Dystrophy, endothelial cells are damaged and lost causing fluid accumulation in the stroma. Medical management has been limited to 5% hypertonic saline drops or ointment, to draw water out of the edematous cornea through osmosis. Once medical treatment fails, chronic corneal edema can lead to bullae, inflammation, fibrosis, opacification, and pannus, which requires surgical management at the end stage. In this study, we induce corneal edema in ex-vivo porcine eyes and compare the effects of 5% hypertonic saline drops to modified hypertonic and hyperosmolar agents as potential therapeutics in reducing corneal edema in ex-vivo porcine eyes. Methods : ...
The Hyper-CL™ lenses are indicated for therapeutic use as a bandage to protect the corneal surface and to relieve corneal pain in the treatment of acute or chronic ocular pathologies, such as bullous keratopathy, corneal erosions, entropion, corneal edema, and corneal dystrophies as well as post-surgical conditions resulting from cataract extraction and corneal surgery. The lenses may be prescribed for daily wear with removal for cleaning and disinfection (chemical, not heat) prior to reinsertion, as recommended by the eye care professional.. In addition Hyper-CL™ contact lenses can also provide optical correction during healing if required.. Prospective open-label, randomized, crossover clinical study To evaluate the safety and efficacy of the Hyper-CL™ lens in subjects suffering from corneal edema..

Purpose: : To clarify the relation between visual acuity after Descemet stripping automated endothelial keratoplasty (DSAEK) and the preoperative duration of stromal edema. Methods: : Twenty-eight subjects who underwent DSAEK were divided into two groups on the basis of a preoperative duration of stromal edema of ,12 months (group A, n = 22) or ≥12 months (group B, n = 6). None of the subjects had postoperative conditions that might have affected the visual outcome of surgery. Best corrected visual acuity (BCVA) was measured at various times after surgery, and the morphology of the anterior cornea was evaluated by in vivo laser confocal microscopy. Results: : BCVA in group A ranged from 20/50 to 20/16 at 3 months and from 20/66 to 20/16 at 6 months after surgery, with the maximal values being 20/40 to 20/13. BCVA in group B ranged from 20/66 to 20/40 at 3 and 6 months, with maximal values of 20/66 to 20/33. The structure of the anterior cornea was normal in subjects of group A but was ...
A 65-year-old man had diffuse, bilateral corneal oedema after acute intake of alcohol. Three days later the total opacification began to clear from the peripheral area towards the centre of the cornea. One month later both corneas were completely clear, and visual acuity was 20/20 in both eyes. Specular microscopy showed in the right eye greatly enlarged endothelial cells, which subsequently shrank, and they showed some pleomorphism six months later. The pleomorphic endothelial cells in the left eye changed little with time. Our findings suggested that the corneal oedema in this patient resulted from temporary endothelial dysfunction with extensive cell loss. ...
This is a common complication of cataract surgery, which usually resolves after 1 week. Those who have more advanced cataracts pre-existing corneal disease are more likely to have corneal edema. The primary treatment is typically steroid drops and hyperosmotic agents such as Muro 128 (a hypertonic saline agent) which pulls the edema fluid out of the cornea. In most cases, the visual prognosis is good.. ...
Corneal edema, or water retention and swelling in the eye, is caused by various medical disorders and even simple viral infections. This medical condition can also result from eye surgeries,...
Stromal swelling in human, cat, and rabbit cornea is biphasic, interpretable as an elementary cusp catastrophe proposed by Thom, with t* ═ log t and Q* ═ log Q (stromal charge Q, time t) as control parameters, and H0.5 (hydration H) as the state variable. A thermodynamic potential with two attractor regions, each with a local minimum, governs corneal stromal swelling. Transitions follow a saturation convention whereby the second minimum is preferred upon availability. Corneal swelling is an example of a space-equivalent unfolding, where the transition plane moves in time. It is proposed that the transition plane coincides with the uncoupling of interfibrillary linkages or springs in the corneal stroma, and is associated with a critical hydration of ca. 10 kg H2O per kilogram dry mass, and stromal charge ca. 1 x 10-7 mol electrons. ...
Sorry you are having so much trouble, I had lasik about the same time as you and also suffered from lingering corneal edema in my left eye and very dry eyes, especially my left one. I also had more bluriness and pain and soreness in my left eye, even at 4 months. See my replies to firemom on her recent posts about dry eye in her recent posts. My major breakthrough with dry eye and lingering corneal edema was to use Alrex drops (very mild steroid) and also warm compresses on my eyes and to stop using any drops with methylcellulose in them. I cant tell you how much better my eyes are now, three weeks after starting that regimen and I noted improvements with dryness just a day or so after starting the compresses and stopping using Refresh Plus and Celuvisc. Now I use plain Refresh and Endura (both preservative-free and in individual things) and also Refresh Sever Dry Eye drops - which are the same as the Endura but in a small bottle with some kind of disappearing preservatives.

Ive been waiting for this appointment with my cornea specialist for weeks. I have been having problems with my left eye since the middle of summer and both my local ophthalmologist and my glaucoma specialist noticed "folds" in my cornea. Both thought that was the reason for my visual acuity dropping from 20/200 to 20/400 in my "good" eye. My right eye has bothered me for the last day or two, so I wanted to have Dr. Ayers take a look there too.. I get called back and the "nurse" (she is more than a helper, but I doubt she is a nurse - please correct me if Im wrong) puts up the eye chart. I see the big E (20/400,) but not the SL (20/200.) She drops the pinhole thingy over my eye and after some searching for the perfect pinhole, I see the SL line. The OPLB line looks like some black blobs and I cant make any of the letters out. The "nurse" says, "Oh, thats not so bad. Its only one line less." Really? So if you are driving down the street, you dont think seeing a sign with letters about 12 ...

Thoroughbred mare Set Chivalry, known to all who love her as Chevy, is a large personality. "Shes so smart and has such a spicy attitude," said owner Susan Lax of the 21-year-old retired dressage horse. "Shes just really the apple of my eye and so exhilarating to ride. I have had her since she was four, and she is a member of our family. I would do whatever is necessary to keep her healthy." Two years ago, Chevy developed glaucoma in her left eye. Local equine ophthalmologists were unable to fix the condition. Then last year, Susan noticed Chevy developing a similar cloudiness in her right eye. She decided to make the nearly three-hour trip from her Hunterdon County, NJ, home to New Bolton Center, where Dr. Nicole Scherrer observed corneal cloudiness and diagnosed her with a painful condition called corneal edema. In a healthy eye, the clear outer portion of the eye is the cornea and this structure stays transparent because it is dehydrated. The corneas endothelium, its innermost layer, plays ...

To present a method, alternative to penetrating keratoplasty, for the restoration of impaired corneal clarity with anterior stromal scarring following long-standing corneal graft failure. A 48-year old female who had previously underwent Descemet stripping automated endothelial keratoplasty (DSAEK) for the treatment of pseudophakic bullous keratopathy, presented with long-standing corneal oedema and anterior corneal scarring. A significant improvement in corrected distance visual acuity was demonstrated, as corneal clarity was restored following graft exchange and phototherapeutic keratectomy (PTK). The combination of corneal graft exchange and phototherapeutic keratectomy may represent an effective therapeutic option for long-standing corneal oedema with concomitant anterior corneal scarring after failure of a DSAEK graft.
The DSEK procedure is most appropriate when there is reduced function of the inner endothelial cell layer - causing corneal edema or swelling (edema).. Normally corneal transparency is dependent on the endothelial cells pumping fluid out of the cornea. If the cornea becomes oedematous, the patients vision worsens. In severe corneal edema, the surface cell layer (epithelium) develops tiny blisters of fluid between the cells (bullous keratopathy). When that happens, the patients vision becomes even worse and the eye can become painful when the blisters rupture.. Corneal endothelial failure is seen in the genetically determined condition of Fuchs corneal endothelial dystrophy, and may also occur following intra-ocular surgery such as cataract extraction.. ...
A variety of medical and surgical options are available to treat corneal hydrops. Topical hyperosmotics, can reduce corneal edema (albeit slowly), and improve acuity. To further manage corneal edema while also reducing the risk for potential neo-vascularization, ODs can prescribe topical steroids-usually starting with a twice-daily dose. Since steroids have the potential to hinder corneal healing or cause corneal perforation, initiating steroid treatment at onset, or even once Descemets membrane heals, is controversial. A cycloplegic agent, typically dosed at twice per day (more if pain persists), can be added to reduce ocular pain from a secondary uveitis. Other options for pain relief include oral or topi-cal nonsteroidal anti-inflammatory agents or a bandage contact lens. However, depending on the severity of the patients keratoconus the lens may fail to fit appropriately with significant edge fluting and decentration. As long as epithelial defects are present, a prophylactic antibiotic ...

The cornea has a white lesion which is most likely to be corneal oedema, there is a widely dilated pupil, a darkened iris and an upwardly luxated lens. These suggest a chronic uveitis with secondary glaucoma and subsequent secondary lens luxation. This histological image shows the iridocorneal angle in a similar case of glaucoma following uveitis, where the drainage angle is being obliterated by inflammatory cells. Amazingly the horse shown in the clinical picture, while having intraocular pressures in the low thirties (in mmHg), still has vision and was ridden by its owner.

Results: Between 1 November 2004 and 1 March 2014 (excluding two interruptions totalling 20 months), 324 eligible patients presented. A total of 167 patients (81 dexamethasone, 86 placebo) were available for the intention-to-treat analysis. Biopsies of 114 patients (68%) were culture-positive. Final BCVA did not differ between the dexamethasone and the placebo group (logMAR 0.31 ± 0.58 versus 0.27 ± 0.50; p = 0.90), nor did the number of patients with final vision of no light perception (LP, 7 versus 13). Pain, corneal oedema, the absence of a red fundus reflex on presentation, LP on presentation and culture of virulent pathogens from biopsy were statistically significantly associated with an unfavourable visual outcome ...

Apparatus for reducing the size of an object (41) disposed in a generally closed fluid medium includes a hand piece (63) having an axis extending from a housing (64) at a proximal end to a probe (65) at an opposing distal end. A reducer (179) at the distal end of the probe (65) is adapted for insertion into the fluid medium (201) where it is rotatable to reduce in size the object (41). The reducer (179) is configured to create a fluid flow (202) in the fluid medium (201) so that the end piece (63) can be maintained laterally and axially stationary while the object (41) is moved (203) by the fluid flow (202) into contact with the reducer (179). An associated method includes the steps of rotating the rotary member (179) at a speed sufficient to reduce the size of the object (41), and in a manner to produce a flow (202) of the fluid (201) sufficient to move (203) the object (41) into the rotary member (179).

Corneal transplant surgery is the most commonly performed of all transplant operations, with approximately 45,000 corneal transplant procedures being performed in the Unites States each year. The indications for corneal transplant surgery have changed through the years. Pseudophakic bullous keratopathy and aphakic bullous keratopathy (corneal edema secondary to cataract surgery) accounted for 80% of corneal transplants in the 1980s. However, with the improvement of cataract surgery techniques, conditions such as Fuchs Dystrophy, Keratoconus, and other corneal dystrophies are now more commonly transplanted.. In 1933, corneal transplants were performed using two razor blades to make a square graft. Patients were hospitalized for two weeks with sand bags on either side of their head to prevent undesirable movement and possible leakage from the wound sites. Since then, there have been major advances in surgical technique including the introduction of the operating microscope (1970s) and better ...
Purpose: To describe outcomes of corneal transplantation for irreversible corneal decompensation from corneal endotheliitis in Asian eyes. Design: Retrospective, observational case series. Methods: We reviewed consecutive patients with corneal endotheliitis (32 eyes of 31 subjects) who underwent keratoplasty (January 1, 2008-December 1, 2009). All eyes had preoperative aqueous polymerase chain reaction (PCR) analysis for viruses, including cytomegalovirus (CMV). CMV-positive patients were treated preoperatively with topical corticosteroids and anti-CMV treatment (oral valganciclovir 900 mg twice daily, topical ganciclovir 0.15% 5 applications per day, for 6 weeks) with complete resolution of ocular inflammation, and quiescence for at least 6 months before corneal transplantation. Our main outcome measure was recurrence of endotheliitis within 1 year after corneal transplantation. Results: Five eyes were CMV positive; the remaining 27 eyes were negative for all viruses on PCR analysis. ...
Human corneal endothelial cells (HCECs) do not replicate after wounding. Therefore, corneal endothelial deficiency can result in irreversible corneal edema. Descemet stripping automated endothelial keratoplasty (DSAEK) allows selective replacement of the diseased corneal endothelium. However, DSAEK requires a donor cornea and the worldwide shortage of corneas limits its application. This review presents current knowledge on the tissue engineering of corneal endothelium using cultured HCECs. We also provide our recent work on tissue engineering for DSAEK grafts using cultured HCECs. We reconstructed DSAEK grafts by seeding cultured DiI-labelled HCECs on collagen sheets. Then HCEC sheets were transplanted onto the posterior stroma after descemetorhexis in the DSAEK group. Severe stromal edema was detected in the control group, but not in the DSAEK group throughout the observation period. Fluorescein microscopy one month after surgery showed numerous DiI-labelled cells on the posterior corneal surface in
Preoperative and postoperative endothelial cell morphology was examined in three types of patients participating in a randomised, controlled trial of cataract surgery. The first sustained modest endothelial cell loss and served as controls, the second and third sustained high cell loss, but only the latter progressed to bullous keratopathy. The technique of examining endothelial cell morphology is described and its validity assessed. Measures of cell area, number of sides, side length, and variation in cell size and cell shape were utilised. No significant differences were found between the three groups by any of the preoperative morphological measures. Furthermore, postoperative values of variation in cell shape and cell size did not differ significantly between the groups. No evidence was found in our patients to support the hypothesis that eyes at particular risk of developing bullous keratopathy may be differentiated on the basis of their preoperative or early postoperative endothelial cell ...
If you have Fuchs dystrophy, one of the first signs may be that you begin to notice glare with headlights at night or in bright sunlight. As the Fuchs dystrophy progresses, your vision may become foggy or blurry in the morning and clear as the day progresses. This occurs because evaporation of fluid from the cornea is decreased while your eyes are closed during sleep, and accumulation of fluid in the cornea during the night results in corneal swelling. This early stage can be treated with a special salt solution or ointment to help pull the water out of your cornea. However, as the Fuchs progresses, your vision will stay blurry longer during the day, and eventually your vision may not clear at all ...
Corneal swelling of 15% or greater, which indicates a gross separation with the collagen fibres with the stroma, results in the hazy or cloudy appearance of your cornea. Theres a physiological oedema happening during rest in every human cornea amounting to an increase in thickness of about 4%.

In this series of patients with corneal opacification secondary to trauma and coexisting vitreoretinal pathologies, combined PPV and PK surgery performed with Landers wide-angle keratoprosthesis resulted in retinal attachment in 6 cases (75%), normotony in 5 cases (62.5%), and graft transparency in 5 cases (62.5%). VA did not decrease in any of the cases, increased in 5 cases (62.5%), and was unchanged in 3 cases. In total, 4 cases (50%) were considered completely successful.. Various alternatives have been used in attempts to perform posterior segment surgeries in eyes with corneal opacities. The main alternatives are performing PK followed by PPV in a separate session, performing simultaneous open sky vitrectomy with corneal excision, or performing PPV with endoscopic methods or temporary keratoprostheses.6. When PK and PPV surgeries are performed in separate sessions, PPV may be delayed due to risks such as persistent corneal edema or graft rejection. Moreover, it has been reported that fluid ...

List of 46 causes for Corneal inflammation and Dark and light patches on the skin, alternative diagnoses, rare causes, misdiagnoses, patient stories, and much more.
Stings from bees or wasps produce a variety of clinical manifestations [1-7]. In cases of corneal bee sting discussed in the literature, corneal complications have been reported most frequently [2-4]. In all these cases, the corneal edema regressed and infiltrates resulted in a corneal scar 4 to 6 weeks after removal of the stinger and the initiation of treatment. Corneal edema has been explained by cell death caused by activation of the complement cascade by proteins in the bee venom, leading to the production of anaphylotoxins and chemotactic factors [1, 3]. Bee venom is a complex toxin having various impacts and components. It contains two types of biogenic amines: non-enzymatic polypeptide toxins (melittin, apamin, mast cell degranulating peptide) and enzymes (phospholipase A, phospholipase B, hyaluronidase). Ocular inflammation increases capillary protein permeability allowing greater leakage of proteins into the vitreous space.. The difference of wasp sting effects depends on the type of ...
Corneal pachymetry is a useful practice: it consists in measuring the corneal depth in order to monitor the cornea guttata and corneal edema status.. In the initial phase it can be treated with a therapy consisting in hyperosmotic agents that draw excess water out of the cornea, making it possible to improve vision, most likely only for a period of time.Later on, it is best to substitute the damages endothelium via an endothelium corneal transplant with the DMEK or DSAEK technique.. ...
Ophthalmic Viscosurgical Device (OVD) is viscoelastic solution used in eye surgery also referred to as viscoelastic agents. Their introduction has had a profound influence on the evolution of extracapsular and phacoemulsification surgery, and their use has decreased the incidence of corneal edema as a complication of phaco surgery. OVDs contain one or more of the following substances in varying concentrations: sodium hyaluronate, chondroitin sulfate, or hydroxypropyl methylcellulose ...
At presentation, there was a facial scar on the right forehead and the tip of nose corresponding to the dermatomal distribution of the ophthalmic division of the trigeminal nerve. The lids were spared. (Figure 1) Examination of the left eye revealed vision of 6/60, with pinhole improvement to 6/36. The corneal sensation was decreased. There were paracentral Descemets folds at the 5 oclock position, measuring 3mm by 3mm with very mild stromal edema, endothelial bullae and localized keratic precipitates. The anterior chamber showed mild inflammation. The pupil was otherwise reactive and round. (Figure 2) The intraocular pressures and ocular movement in both eyes were normal. Visual acuity in the right eye was 6/9. The examination of the right eye did not reveal any abnormality despite being on the same side with the facial scar ...

A new predictor of cornea transplant success has been identified by the Cornea Donor Study (CDS) Investigator Group. New analysis of data from the 2008 Specular Microscopy Ancillary Study (SMAS), a subset of the CDS, found that the preoperative donor cell count of endothelial cells, previously considered to be an important predictor of a successful transplant, did not correlate with graft success. Instead the study found that a patients endothelial cell count six months post-cornea transplant is a better indicator of subsequent failure of the graft rather than the donors cell count. These results offer an additional, reliable indicator of success that surgeons can use for monitoring patients at the six-month milestone after transplantation. ...

An experiment was conducted to evaluate the effect of naked neck (,I,Na,/I,) gene, sex and their interaction on immunocompetence of chickens. Three genotypes (,I,NaNa, Nana,/I, and ,I,nana,/I,) were the offspring of heterozygous naked neck (,I,Nana,/I,) Fayoumi (Egyptian breed) males and females. They were reared under similar environmental, managerial and hygienic conditions. The present results showed that the ,I,NaNa,/I, birds had lower mortality rate as compared to ,I,Nana,/I, and ,I,nana,/I, counterparts. The ,I,NaNa,/I, genotype had significantly heavier 8wk-body weight and higher relative weights of bursa, spleen, heart and liver compared to nana sibs. With respect to cutaneous basophilic hypersensitivity (CBH) response, the presence of ,I,Na,/I, gene in a double state significantly increased dermal swelling response to phytohemagglutinin-P (PHA-P) injection compared to nana counterparts. The ,I,Nana,/I, genotype was intermediated in the most cases. Dermal swelling response to PHA-P, ...

Fuchs Dystrophy is a type of corneal disease that affects the inner most layer of the cornea-the endothelium. Fuchs Dystrophy is slowly progressive, is found in both eyes and is slightly more common in women than men. While we can see Fuchs Dystrophy in people in their 30s and 40s, it usually does not compromise vision until people are in their 50s or 60s.. About Fuchs Dystrophy. The endothelial cells are responsible for pumping water out of the cornea and helping to maintain the corneal transparency. While the reason is poorly understood, in Fuchs Dystrophy, the endothelial cells die, which make the endothelium less efficient in its pumping activity. This results in the cornea swelling and distorting vision. Fuchs Dystrophy Risks & Severity. Researchers reporting in the journal Investigative Ophthalmology and Visual Science studied the effects of smoking, and other risk factors, on the development of advanced Fuchs endothelial corneal dystrophy (FECD) and on central corneal thickness ...
Case Report DOI:10.14744/bej.2019.79553 Beyoglu Eye J 2019; 4(2): 126-129 Manual Intracorneal Silicone Oil Insertion for Symptomatic Treatment of Bullous Keratopathy in a Patient with Corneal Scarring Selim Genc, Semih Cakmak, Yusuf Yildirim Department of Ophthalmology, University of Health Sciences, Beyoglu Eye Training and Research Hospital, Istanbul, Turkey Abstract Bullous keratopathy is a result of endothelial loss and the failure of the remaining corneal epithelium to pump leaking water molecules away from the corneal tissue, causing overhydration. In eyes with good visual potential, keratoplasty is the primary treatment. There are also several other approaches to provide temporary improvement until a permanent solution with keratoplasty can be achieved. These alternatives include hypertonic topical sodium chloride (5%) drops, bandage contact lenses, anterior stromal puncture, phototherapeutic keratectomy, amniotic membrane transplantation, conjunctival flaps, and collagen crosslinking. ...
A previously fit and well 55-year-old man on no medication presented to Eye Casualty with a 2-day history of bilateral blurred vision and unsteadiness. His best-corrected visual acuities (BCVA) were hand movements and 6/18 in the right and left eyes, respectively. Examination revealed bilateral limitation of extraocular movements in all gaze positions, sluggish pupillary responses, bilateral corneal oedema, shallow anterior chambers and IOPs of 56 and 48 mm Hg (normal range 10-21 mm Hg). (figure 1A). Gonioscopic assessment of the iridocorneal angle was precluded by corneal oedema. There was no proptosis, ptosis or periorbital swelling.. ...

Methods: Observational case report. Results: Stromal edema localized inthe graft developed 42 days after ALTK for Avellino corneal dystrophy in a 65-year-old man. After one week of intensive topical corticosteroids, complete reversal of graft edema occurred, with full recovery of visual function. Conclusion: The clinical appearance and response to therapy in this case supported the diagnosis of immune-mediated stromal rejection. Ophthalmologists should be aware that stromal rejection may occur in ...
Fuchs corneal endothelial dystrophy is an inherited eye condition, which may cause your cornea to become cloudy.Fuchs dystrophy develops slowly and can affect people to a varying degree. While some people may never have any real problems with their vision, others can require a corneal treatment quite early in life.
BCVA was hand motion at presentation. Intraocular pressure was 4 mmHg. In slit lamp exams, conjunctival injection, corneal edema, Descemet fold, anterior chamber and anterior vitreous cells were obvious. Pars plana deep vitrectomy with peripheral vitreous shaving and silicone oil tamponade was performed. Electroretinography showed undetectable responses. In ultrasound biological microscope (UBM) evaluation ciliary body shortening and detachment was documented. Optical coherent tomography showed diffuse retinal edema the day after surgery, subretinal fluid pockets in two weeks, and complete attached retina but atrophic with undetectable and intertwined layers two months later. Gradually, like the retina, iris became atrophic and pigments were dispersed diffusely over the lens and endothelium ...

CLPUs differ from peripheral corneal hypersensitivity-induced conditions, such as marginal ulcers, and phlyctenulosis, even though they all involve staphylococcal antigen hypersensitivity. Marginal ulcers are typically oval in shape, are located at the 2, 4, 8 and 10 oclock positions and run parallel to the limbus. Although the infiltrate is always separated by a clear interval, it can be spanned by blood vessels. In distinction, CLPUs can occur at any position in the peripheral cornea. There is no clear interval, as infiltrates are seen to stream from the limbal vasculature to the focal infiltrate, and there are no bridging vessels. CLPUs differ from corneal phlyctenules, as there is no raised nodular infiltrate or vascularization ...

1. In America, down south in Nashville, Tennessee is a very popular city. Its streets bustled with people who had business with others, either about contracts for new buildings, or new businesses, or new stars that were ready to make their names known in the world. The city was a glorious sight to many people, but the city is not where this story begins. This story begins in the suburbs of Nashville, where a young girl with short, dark hair lay in her messy bed, covered in sheets, and drooling slightly on her pillow.. She groaned as the sunlight hit her face, and turned over in her bed to keep it from hitting her closed eyes. Although, it didnt make much difference in how well she slept, for her mother soon came knocking on the door.. "Leanne?" Her mother called from the other side of the door, "Leanne, you better be awake in there!" The girl in the sheets curled up unhappily, putting her pillow over her head to block out the noise of her mother banging on her bedroom door.. "Go away…!" She ...

When your body appears the symptom of edema, some people consider it is a small trouble. Actually, it is not true. What diseases can cause edema? Looking through this article can help you figure out the answer of this problem. First of all,
Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal, and acanthamoeba keratitis), corneal opacity and scarring, keratoconus, bullous keratopathy, regrafting, corneal dystrophy and degeneration, herpes simplex keratopathy (active keratitis), etc. were considered as indications of corneal transplantation. Results: A total of 186 patients (110 males, 76 females) were included in the study. Mean age of patients was 47.7± 24.3 years (6-85). The leading indications of grafting was corneal opacity (32.3%) followed by keratoconus (22.6%), bacterial keratitis (15.6%), aphakic bullous keratopathy (6.7%), pseudophakic bullous keratopathy (6.5%), regrafting (4.8%), herpes
In corneal transplant, also known as keratoplasty, a patients damaged corneais replaced by the cornea from the eye of a human cadaver. This is the single most common type of human transplant surgery and has the highest success rate. Eye banks acquire and store eyes from donor individuals largely to supplythe need for transplant corneas.. Corneal transplant is used when vision is lost in an eye because the cornea has been damaged by disease or traumatic injury. Some of the disease conditions that might require corneal transplant include the bulging outward of the cornea (keratoconus), a malfunction of the inner layer of the cornea (Fuchs dystrophy), and painful swelling of the cornea (pseudophakic bullous keratopathy). Some of these conditions cause cloudiness of the cornea; others alter itsnatural curvature, which can also reduce the quality of vision.. Injury to the cornea can occur because of chemical burns, mechanical trauma,or infection by viruses, bacteria, fungi, or protozoa. Herpes ...
Immediately after the procedure, you will be taken into recovery where you will lie down for about an hour to let the air bubble continue to press against the tissue to secure it in place. Your eye will be patched before you leave. Antibiotic eye drops will be used for a week or so to help prevent infection, and a mild steroid eye drop will need to be used for a year or so to help prevent rejection.. You should be able to resume normal activities the day after your surgery. With conventional corneal transplantation, your vision typically does not improve for months or even years, while with DSAEK, you may experience visual improvement within weeks. If you need transplants in both eyes, DSAEK allows you to have the second transplant within months, versus a year or more if you were to have a conventional transplant.. In order to make your DSAEK procedure a success, it is important that ALL scheduled appointments be kept and ALL medications are used as directed. Any pain, redness, or reduced vision ...
Aim: To establish an in vitro human corneal decompensation model and to use it for the evaluation of a cell-therapy approach for treating corneal endothelial (CE) disorders and to test the expression profile of positive regulatory domain proteins (PRDMs) as potential markers for corneal endothelial cells (CECs). Materials and Methods: Human cadaveric corneas were obtained from Bristol and Manchester Eye Banks, UK. A CE decompensation model was established by removal of the Descemets membrane (DM)/Endothelium complex from donor corneas and placing them in air-interface organ culture. The corneal thickness was used as a surrogate measure of CE function and was measured using Optical Coherence Tomography (OCT). Decompensated corneas were subjected to cultured endothelial cell therapy using immortalized HCEC -12 cells (group 1), primary human corneal endothelial cells (hCECs) at 0 passage (group 2) and hCECs at passage 2 (group 3) with defined seeding cell density. The effect on stromal de-swelling ...
Graphic from: From Høeg TB, Corrigan GK, Hoffman MD. An investigation of ultramarathon-associated visual impairment. Wilderness Environ Med. 2015 Jun;26(2):200-4. doi: 10.1016/j.wem.2014.10.003. Epub 2015 Feb 26.. The increased risk among those with a history of refractive surgery may suggest that these corneas do not respond as well to prolonged environmental irritation. Of note, approximately three quarters of the participants with vision loss had never had refractive surgery. But those who had also experienced vision loss more frequently. It was also significantly linked to being female, but that may be because females are more likely to take surveys than males (Høeg, 2015),. This type of vision loss does not appear to have any long-term visual consequences. Exercise-related corneal edema has also been documented in cyclists (Ettl, 1992). Athletes who have recurrent running or cycling related vision loss can be counseled to compete with protective eyewear and/or use artificial tears ...
Introduction: The purpose was to investigate the clinical and tonometric alterations in glaucomatous dogs treated with intravitreal uveal ablation. Material and Methods: It was evaluated 13 canine eyes of dogs who were examined on the Ophthalmology Service of Veterinary Hospital in the University of Veterinary Medicine and Animal Science-UNESP-Botucatu, presenting unilateral chronic glaucoma with irreversible blindness. After general anesthesia, the sick eyes of the dogs was submitted to intravitreal uveal ablation, through vitreous chamber injection of 0,5ml of gentamicin sulfate solution (40mg/ml) associated with 0,3ml of dexamethasone dissodic phosphate (4mg/ml). All dogs were evaluated across scores varying of 0 to 3, indicating absent, discreet, moderate and intense, respectively, to evaluation of following clinical signs: secretion, conjunctival hiperemy, corneal edema, quemosis, blepharospasms, hifema, neovascularization, pigmentation and pannus. Scores varying of 0 to 2, indicating ...

Pre Descemets endothelial keratoplasty (PDEK) is a kind of endothelial keratoplasty, where the pre descemets layer (PDL) along with descemets membrane (DM) and endothelium is transplanted. Conventionally in a corneal transplantation, doctors use a whole cornea or parts of the five layers of the cornea to perform correction surgeries. In May 2013, Dr Harminder Dua discovered a sixth layer between the stroma and the descemet membrane which was named after him as the Duas layer. In the PDEK technique, doctors take the innermost two layers of the cornea, along with the Duas layer and graft it in the patients eye. The normal cornea (Fig 1) has from the front to the back the following layers: 1. Epithelium 2. Bowmans membrane 3. Stroma 4. Pre Descemets layer 5. Descemets membrane 6. Endothelium For the human eye to see, the cornea or the front window of the eye should be clear or transparent. For that to happen the inside corneal layer the endothelium pumps out water from the cornea so that the ...

Thicker corneas and steeper posterior corneal curvature were seen in eyes that underwent Descemets stripping automated endothelial keratoplasty compared with eyes that underwent Descemets membrane endothelial keratoplasty, according to a study. The retrospective study included 20 eyes of 10 patients with Fuchs endothelial dystrophy who underwent DSAEK in one eye and DMEK in the contralateral eye. Four DMEK eyes and three DSAEK eyes had cataracts that were removed concurrently with corneal transplantation. Four DMEK eyes and four DSAEK eyes were pseudophakic and had posterior chamber IOLs. Two DMEK eyes and (Read more...) Full Story →. ...
Erythrocyte sedimentation rate was 97 mm per hour, and temporal artery biopsy showed chronic inflammation with giant cells. Carotid doppler revealed moderate stenosis of the right internal carotid artery and mild stenosis of the left internal carotid artery with normal flow. The patient was given a 6-week course of systemic corticosteroids, but at 3-month follow up, there was no recovery of vision in the right eye.. There are several reports of corneal involvement in GCA (3-5). However, hypotony occurs infrequently, and it is thought to be caused by a reduction in aqueous production as a result of inflammation of the ciliary body (2-4,6-8). Hypotony was detected in one third of patients without other signs of anterior segment ischemia in a study by Huna-Baron et al (2). They suggested that low intraocular pressure may help distinguish arteritic from nonarteritic anterior ischemic optic neuropathy.. Mild corneal edema and Descemet folds have been reported in GCA (3-5) in several cases, but severe ...
