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...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2016217023 DESCRIPTION A 77-year-old woman underwent pars plana vitrectomy for recurrent retinal detachment with silicone oil injection 10 years before presentation. Also the patient was placed on antiglaucoma medications. The patient had a history of recurrent corneal ulcerations in both eyes du...

Corneal collagen cross-linking (CXL) halts human corneal ectasias progression by increasing stromal mechanical stiffness. Although some reports describe that this procedure is effective in dealing with some infectious and immunologic corneal thinning diseases, there is a need for more animal models whose corneal thickness more closely resemble those occurring in these patients. To meet this nee...

After unilateral total iridectomy, maximum accommodation inducible by corneal iontophoresis of carbachol in rhesus monkeys was approximately 40% less in the iridectomized than in the contralateral untouched eyes, irrespective of age. Ultrasonographically measured anterior chamber shallowing and lens thickening were also less in the iridectomized eyes. Neither submaximal accommodation induced by...

The morphologic effects on rabbit corneal endothelium of several common ophthalmic vehicle constituents were examined following subconjunctival administration. Profound dose-dependent changes consisting of intercellular vacuolization and thickening of the endothelial layer were noted within 1 day following administration of solutions that contained sodium bisulfite or methylparaben and propylpa...

Objective: A coccygeal pad is a nodular lesion in the sacrococcygeal area. It is a rare disease characterized by corneal thickening, the proliferation of collagen bundles, and an anterior flexed coccyx. In the English literature, 42 patients have been reported. Methods: We present a young male case of a typical coccygeal pad with an anterior flexed coccyx. Results: After resection of the nodule...

We report a second clinico-pathologic report of recurrent keratoconus in a 43-year-old white female with bilateral penetrating keratoplasties for keratoconus. She was found to have a recurrence of this condition in the right eye as manifested by increasing myopic oblique astigmatism, subepithelial and anterior stromal scarring and corneal thinning, 22 years following the initial grafting proced...

Background & Aims: This study was carried out to determine the leading indications for corneal transplantation in Kerman province. Methods: Medical records of 186 patients underwent corneal transplantation during 3 years (2004-2006) in Shafa Medical Center were evaluated retrospectively. The initial diagnosis and causes of corneal grafting were recorded. Infectious keratitis (Bacterial, Fungal,...
