Cytotoxic brain edema (swelling due to increased intracellular fluid) is indicative of a disturbance in cell metabolism, and is commonly associated with hypoxic or ischemic injuries (see HYPOXIA, BRAIN). An increase in extracellular fluid may be caused by increased brain capillary permeability (vasogenic edema), an osmotic gradient, local blockages in interstitial fluid pathways, or by obstruction of CSF flow (e.g., obstructive HYDROCEPHALUS).

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.. ...

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. I have also been on ...

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.

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.
During JANUARY 8-14, 1998, six of eight patients undergoing elective intraocular surgery at a Veterans Affairs medical center (VAMC) in St. Louis, Missouri, developed corneal endothelial decompensation (corneal edema and opacification) 24 hours after surgery. All had been operated on with instruments sterilized by the Abtox Plazlyte system (Abtox, Inc., Chicago, Illinois).1 This report summarizes
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.. ...
TY - JOUR. T1 - Corneal hydration imaging using dual-wavelength optical coherence tomography. AU - Jeon, Sung W.. AU - Shure, Mark A.. AU - Rollins, Andrew M.. AU - Huang, David. PY - 2004/10/27. Y1 - 2004/10/27. N2 - Corneal hydration plays an essential role in maintaining optimal vision. During laser ablation surgery, corneal hydration varies greatly and is likely to affect the outcome. Quantitative measurements of this interaction during surgery may help improve the results of vision correction surgery. In addition, prescreening of corneal hydration could be used to correct the laser surgery procedure for hydration variation in the patient population. We present a functional extension of Optical Coherence Tomography (OCT) to measure cornea hydration in vitro using two light sources simultaneously, one at 1294 nm (negligible water absorption loss) and another at 1410 nm (large water absorption loss). Measuring the ratio of the intensity depth profile at these two wavelengths allows us to ...
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 ...

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. ...
View more ,Purpose: To examine the magnitude and time course of central epithelial, stromal and total corneal thickness changes during sealed miniscleral contact lens wear and the influence of initial central corneal clearance upon these thickness changes. Methods: High-resolution OCT images were captured over an 8 h period of miniscleral contact lens wear (using a rotationally symmetric 16.5 mm diameter lens) in 15 young, healthy participants with normal corneae. Corneal thickness data were derived from OCT images using semi-automated image processing techniques over the central 4 mm. Results: Changes in stromal and total corneal thickness followed a similar pattern throughout lens wear with oedema first detected 15 min after lens insertion (0.47 ± 0.09% increase in stromal and total corneal thickness, both p , 0.01) which peaked after 90 min of lens wear (1.36 ± 0.24% increase in stromal and 1.18 ± 0.20% increase in total corneal thickness, both p , 0.01) and gradually decreased thereafter. ...
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 ...

Methods: Tissue sections of formalin-fixed, paraffin-embedded corneal specimens (keratoconus, pseudophakic bullous keratopathy, epithelial downgrowth, failed corneal grafts with retrocorneal fibrous membranes, and postmortem control corneas) were immunostained with a panel of corneal epithelial and endothelial markers (EMA, KAE 1/3, CAM5.2, Factor VIII, CD-34, CD-31) and with Vimentin using the Strept-Avidin technique (Dako). Results: Corneal endothelium is immunonegative for endothelial cell markers (CD-34,CD-31, and Factor VIII) and displays immunopositivity for epithelial markers (KAE 1/3, CAM 5.2). ...
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 ...

Purpose: Although the frequency in which practitioners are fitting scleral contact lenses is increasing, the recommendation for proper tear layer depth (thickness) varies amongst experts. The main goal of this paper is to clinically verify the effect of varying tear layer depths on induced corneal edema during lens wear. Methods: Ten subjects with healthy eyes were fitted with scleral lenses on their right eye. Each of them was fit with two different lenses: one with an apical clearance of 200 μm and another with an apical clearance of 600 μm. They wore the lenses for 8 hours on two different days, with at least a one week wash-out period. Lenses were applied at 8 a.m. on each of the testing days. Pachymetry measurements were taken one day prior to lens wear at 4 p.m., on the day of wear prior to lens application, and after removal of the lenses at 4 p.m. Measurements were collected using both the Pentacam® HR Corneal Tomographer, as well as the Visante Anterior Segment Optical Coherence ...

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 ...

Despite the name, the eye itself is not affected. Blunt force or trauma to the eye socket results in burst capillaries and subsequent haemorrhaging (hematoma).[1] The fatty tissue along with the lack of muscle around the eye socket allows a potential space for blood accumulation. As this blood is reabsorbed, various pigments are released similar to a bruise lending itself to the extreme outward appearance.[1] The appearance (discoloration purple black and blue and swelling) does not necessarily indicate a serious injury, and most black eyes resolve within a week. The tissues around the eye are soft and thus bruise easily when pinched against margins of bone which surround the eye socket. The treatment of black eye is the same as that for bruises in other parts of the body - cold compresses during the first twenty-four hours and contrasting hot and cold thereafter. During the process of healing, a black eye can be made less conspicuous by using cosmetics designed to obscure discolorations of the ...
