the past decade has witnessed the revival of amniotic membrane transplantation (amt) in ophthalmology. the importance of amt is due to its ability to reduce scarring and inflammation and to enhance wound healing and epithelialization, and also its anti-microbial properties. amniotic membrane has recently been used as a substrate for culturing limbal stem cells for transplantation. it has been u...

To the Editor: In their article, which was published in the September 2008 issue of the Journal of Refractive Surgery, Krueger et al1 detailed their use of an adapted version of Wollensak et al’s2 corneal collagen cross-linking (CXL) therapy to treat a patient with bullous keratopathy. Although the patient’s symptoms appeared much improved at 6-month follow-up, the safety of such a treatment, i...

PURPOSE To evaluate anterior segment modifications after penetrating keratoplasty (PKP), previous anterior chamber intraocular lens (IOL) removal, and Verisyse IOL (AMO) implantation over the iris or under the iris for the treatment of pseudophakic bullous keratopathy (PBK) using ultrasound biomicroscopy. SETTING Department of Ophthalmology, Poitiers University Hospital, Poitiers, France. M...

Vitreous samples were obtained from 41 eyes undergoing vitrectomy, and radioimmunoassays were performed to measure concentrations of the prostaglandins PGE2, PGF2 alpha, prostacyclin, and thromboxane. Presumably physiological levels (approximately 100 picograms/ml) were found in vitreous from eyes undergoing cataract extraction. Eyes with vitreous haemorrhage, retinal detachment, or cystoid mac...

BACKGROUND Bullous keratopathy (BK), a severe sight-threatening disorder can have a variety of etiologies such as prophylactic laser iridotomy, intraocular surgery, trauma, and other ocular disorders. However, there are cases of unknown origins, among which a unique clinical entity namely pseudoexfoliation syndrome (PEX) is having increased importance. CASE PRESENTATION In this case note, we ...

We report here three patients who underwent combined Descemet's stripping with endothelial keratoplasty and transconjunctival pars plana vitrectomy for bullous keratopathy and posterior segment pathology. A surgical technique and case histories are described. Anatomic and visual outcomes of combined Descemet's stripping with endothelial keratoplasty and vitrectomy were excellent. Our experience...

68 eyes in which Choyce Mark VIII anterior chamber lenses had been implanted were examined, all surgery having been performed by Mr. Choyce. The average time since implantation was 5-5 years aand in 85 per cent. of eyes the corrected visual acuity was 6/12 or better. Bullous keratopathy, corneal epithelial oedema, and peripheral anterior synechiae giving rise to glaucoma were the most serious c...

A 64-year-old Caucasian man referred for decreased vision after selective laser trabeculoplasty (SLT). Slit lamp examination revealed diffuse corneal edema. Despite intensive topical treatment including steroids, corneal edema did not resolve; on the contrary, it advanced to bullous keratopathy. Corneal edema after SLT is an exceptionally rare complication and in all of the previous reports ede...
