Abstract: Corneal perforations are ophthalmological emergencies which can have serious and detrimental consequences, if not managed timely and appropriately. These are a significant cause of ocular morbidity and can result in decreased vision, blindness, and even loss of the eye. Corneal perforations can be managed using a range of treatment approaches, including temporary solutions such as the application of corneal glue and bandage contact lens, as well as definitive treatment such as corneal ...

We present the case of a 47-year-old woman with bilateral iridocorneal endothelial syndrome. The iridocorneal endothelial syndrome has heretofore been considered a unilateral disorder. However, a review of the literature and examination of the patient presented in this report indicate that bilateral occurrence of the iridocorneal endothelial syndrome is not uncommon. Consequently, it may be inappropriate to include unilaterality as a feature distinguishing the iridocorneal endothelial syndrome from ...

We studied the occurrence of ulcerative keratitis in five eyes of four patients who were examined at the University of Maryland Hospital ophthalmology clinic over a 12-month period. All were young women who were intravenous drug abusers, with no known pre-disposing factors for ulcerative keratitis. Two patients had acquired immunodeficiency syndrome (AIDS), one was human immunodeficiency virus (HIV)-positive, and the fourth refused HIV testing. One had a corneoscleral limbus to corneoscleral limbus ...

Background: Eighteen patients with chronic ocular irritation were examined over a 3-year period. All patients demonstrated papillary conjunctivitis and, occasionally, tarsal ulcers. Six also had floppy eyelid syndrome. Underlying every patient's symptoms was the overriding or imbrication of a lax upper eyelid on an often equally lax lower eyelid, allowing lower eyelid lashes to chronically rub the upper eyelid tarsal conjunctiva. Methods: Chronic ocular irritation in five patients was managed with ...

These epitopes are parts of sequences at the ...

Background: Conventional treatment of corneal stromal vascularization is often inadequate. The authors developed a rabbit model of corneal stromal vascularization, treated it with laser photocoagulation, and then studied the histopathology. Methods: A reproducible model of corneal stromal vascularization was developed in albino rabbits by injecting sodium hydroxide into the corneal stroma. Corneal stromal vascularization was produced in both eyes of 13 rabbits, and treated after stabilization at ...

Five consecutive patients underwent epikeratoplasty for keratoconus. Postoperatively, four patients had poor visual acuity (average, 20/200) secondary to folds in Descemet's membrane and interface scarring. Two underwent penetrating keratoplasty eight months later. Histopathologic examination of the host corneas and the overlying lenticules disclosed epithelial irregularity and subepithelial fibrosis. The host corneas showed folds in Descemet's membrane and focal posterior stromal fibrosis. Electron ...

The authors describe a new surgical approach used in six consecutive patients referred to us between August 1986 and August 1988 with massive suprachoroidal hemorrhage (MSCH) during or after cataract extraction (4 patients), glaucoma filtering surgery (1 patient), or scleral buckling (1 patient). All patients had large hemorrhagic choroidal detachments with five eyes showing “kissing” detachments. Secondary surgery was delayed 7 to 25 days (mean, 14 days) to allow liquefaction of the blood clot and reduce ...

Corneal argon laser photocoagulation (CALP) was used in 13 patients to treat deep stromal vascular ingrowth. Eight patients had undergone successful penetrating keratoplasty but had developed deep stromal vessels into the graft associated with signs of graft rejection, which did not improve with steroid treatment alone (group 1). After CALP; there was marked regression of the neovascularization with reversal of graft rejection in all eyes. Three additional patients with vascularized corneas, referred ...

The posterior cell layer of the normal human cornea or "endothelium" was investigated by electron microscopy and immunocytochemistry. Ultrastructurally, the cells lacked the characteristic marker for endothelial cells (Weibel-Palade body). Immunoperoxidase studies demonstrated these cells to be negative for factor VIII antigen, but strongly positive for keratine, vimentin, S-100 protein, and neuron-specific enolase. The anterior epithelial cell layer showed identical immunoreactivity. These studies ...

Five patients received clindamycin and prednisolone, sulfadiazine, pyrimethamine, or cryocoagulation, or a combination of these. All patients with the acute disease had the characteristic foci and a positive titer on the Sabin-Feldman dye test of at least 1:16. Other causes of retinochoroiditis were excluded. ...

These included foreign-body sensation, pain, contact lens intolerance, giant papillary conjunctivitis, tarsal ulceration, conjunctival granuloma, corneal infiltrate, and corneal vascularization. These changes followed cataract surgery, corneal transplantation, and pars plana vitrectomy. Diagnoses in these cases were made by careful slit-lamp examination and by eversion of the upper eyelid.

• Lens opacities secondary to argon laser photocoagulation were seen in six eyes of four patients undergoing treatment for subretinal neovascular membrane and diabetic retinopathy. Laser-induced lens opacities were multiple, grayish-white, and localized at the junction of the nucleus and anterior cortex of the lens. These lens opacities were stable and nonprogressive. Laser-induced lens opacities are a potential complication of photocoagulation treatment in patients with nuclear sclerosis.
