Aims: To study the long term toxic effects of intraocular benzalkonium chloride (BAC). Methods: 19 patients exposed to intraocular BAC preserved viscoelastic during cataract surgery in February 1999 developed severe striate keratopathy immediately postoperatively. 16 patients, including two who underwent penetrating keratoplasty, were studied in the period April to June 2000. Ocular symptoms, v...

PURPOSE To report the indications and techniques of corneal transplantation at a tertiary referral center in Tehran over a 3-year period. METHODS Records of patients who had undergone any kind of corneal transplantation at Labbafinejad Medical Center, Tehran, Iran from March 2004 to March 2007 were reviewed to determine the indications and types of corneal transplantation. RESULTS During th...

background: human cornea expresses functional fas-ligand capable of killing fas+ activated lymphocytes. fas expression is partly regulated by -670 a/g polymorphism in the promoter region of fas gene. objective: the aim of the present study is to determine the association between fas-670a/g polymorphism and survival of corneal transplantation. methods: in 276 graft recipients who mainly underwen...

The surgical indication for Descemet-stripping automated endothelial keratoplasty (DSAEK) is largely limited to phakic or pseudophakic cases of endothelial dysfunction with normal pupils, because the endothelial lenticule is generally attached to the recipient cornea by use of gas tamponade into the anterior chamber. Although it may be desirable for vitrectomized cases with aniridia and aphakic...

Purpose To report a case of bilateral iridoschisis with cataracts and corneal decompensation in a patient who underwent cataract extraction and superficial iridectomy followed by Descemet membrane endothelial keratoplasty (DMEK). Observations A 58-year-old man with previously diagnosed iridoschisis, cataracts, and diabetes mellitus experienced progressive vision loss bilaterally due to cornea...

DeepVein Thrombosis FollowingDescemet Stripping Automated Endothelial Keratoplasty Venous thromboembolism is the secondmost commonmedical complication after surgery.1 The risk factors for development of deepvein thrombosis (DVT) include age, obesity, and diabetesmellitus.1Deepvein thrombosis associatedwithophthalmic surgery, specifically vitreoretinal surgery, has been reported.2 Descemet strip...

Fuchs endothelial dystrophy had DSAEK in the left eye for bullous keratopathy after cataract surgery and trabeculectomy in 1997. Preoperatively, the BSCVA in this eye was 20/200. On the first postoperative day, characteristic interface wavelike deposit accumulation was visualized on slitlamp examination despite corneal edema (Figure 2). A short trial of intensive steroids (from 4 times initiall...

We herein report two cases of occult Descemet's membrane detachment (DMD) after phacoemulsification surgery, which initially presented as persistent corneal edema and had been considered as pseudophakic bullous keratopathy. The patients were thus scheduled to receive corneal transplantation. For Case 1, DMD was incidentally detected by slit-lamp examination 2 months postoperatively, only when p...

Objective. To report a case of toxic anterior segment syndrome (TASS) that was caused by inadvertent anterior chamber and cornea stromal injection with high dose gentamicin following cataract surgery. Methods. Case report. Results. We report a 72-year-old female patient who developed TASS that was caused by high dose gentamicin (20 mg/0.5 mL), which was inadvertently used during the formation o...
