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.. This study is designed to evaluate the efficacy of the Hyper-CL™ lens contact lens on corneal edema thickness as compared with salt solution treatment only in subjects suffering from ...
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.

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.
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.

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%.

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 ...

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 ...
