Two patients with an atypical form of band keratopathy following long-term pilocarpine treatment are described. The keratopathy is thought to have resulted from the presence of the preservative phenylmercuric nitrate in the pilocarpine drops. Symptoms of reduced acuity, visual haloes, and recurrent epithelial erosions were relieved by removal of the opacities.

A comparison was firstly done of the oxygen flux through the Bausch and Lomb Plano T lens, the Bausch & Lomb U3 lens, and the Duragel 75 lens with a sensor on the normal eye. The results showed that the Bausch and Lomb Plano T lens was the best for use with the sensor probe. The sensor was then used to obtain a comparison with the normal oxygen flux through a therapeutic lens on keratoplastic e...

INTRODUCTION Corneal damage associated with abuse of topical anesthetics is a rare clinic entity. Topical anesthetic abuse is one of the causes of ring keratitis. Ring keratitis is easily overlooked because it can mimic acanthamoeba keratitis or other infectious keratitis. The outcome is often poor, leading to persistent epithelial defects, corneal scarring, and perforations. CASE PRESENTATIO...

purpose: to determine the indications for penetrating keratoplasty (pk) in iran over an 11-year period. methods: all eye bank records of patients who underwent pk from 1994 to 2004 at ophthalmologic centers throughout iran were reviewed. results: during this 11-year period, a total of 19,668 cases were operated. the most common indication for penetrating keratoplasty was keratoconus (34.5%), fo...

The tissue reaction to a functioning Molteno implant has been studied by light microscopy and by scanning and transmission electron microscopy. The material was obtained from an aphakic 83-year-old human eye which required enucleation because of intractable bullous keratopathy, despite well controlled intraocular pressure. The tissue response around the silicone rubber tube was that of simple f...

In a series of 227 consecutive, non-referred patients with microbial keratitis an analysis of the accumulated hospital records showed that one-third were associated with chronic alcoholism. The diagnosis of alcoholism was usually unsuspected on admission to hospital. The microbial pathogenesis in these patients was distinctive; coagulase-negative staphylococci, alpha- and beta-streptococci, mor...

Corneal collagen cross-linking with riboflavin and UVA light is a new therapeutic method for increase the biomechanical stability of the cornea through induction of new additional links between collagen fibers. The aim of this paper is to show the mechanism of action of this therapeutically method in different corneal diseases, for which this method can be applied: corneal ectasia, bullous kera...
