The electron microscopic appearances of the corneoscleral and iris tissue removed at operation from a child with Hurler disease and glaucoma showed distinctive swollen cells with intracellular inclusions similar to those which are observed in other tissues in these patients and which are due to abnormal lysosomal storages of mucopolysaccharides. Some recent observations on the possible relation...

PURPOSE To report a case of Propionibacterium acnes endophthalmitis in a patient with an Ahmed glaucoma valve. CASE REPORT A nine-year-old boy with bilateral congenital glaucoma, with an Ahmed glaucoma valve implanted in the left eye, had recurrent conjunctival dehiscence and endophthalmitis. RESULTS Vitreous cultures demonstrated the presence of Propionibacterium acnes. CONCLUSIONS This ...

OBJECTIVE To describe surgical strategies in a series of patients with diplopia following implantation of a glaucoma drainage device. METHODS Retrospective review of 9 consecutive patients who underwent strabismus surgery because of strabismus and diplopia after implantation of a glaucoma drainage device. RESULTS Seven patients with marked limitation to ocular rotations and incomitant strab...

BACKGROUND Inflammation associated with biomaterials may contribute to the failure of glaucoma drainage devices. OBJECTIVE To compare the inflammatory reaction associated with the insertion of Krupin silicone, Molteno polypropylene, and Acrosof end plates in the subconjunctival space of rabbits. METHODS Similar-sized glaucoma end plates made of 3 different biomaterials were sutured to the s...

Polymorphisms in the CAV1/2 genes that encode signature proteins of caveolae are associated with glaucoma, the second leading cause of blindness worldwide, and with its major risk factor, intraocular pressure (IOP). We hypothesized that caveolin-1 (Cav-1) participates in IOP maintenance via modulation of aqueous humor drainage from the eye. We localize caveolae proteins to human and murine conv...

Posterior pupillary synechiae affect a proportion of eyes subjected to iridectomy with or without drainage operation because (1) aqueous humour bypasses the pupil; (2) traumatic iridocyclitis occurs; (3) there is immobility of the iris in the iridectomy sector; (4) in eyes with angle closure glaucoma closer apposition of the iris to the anterior lens capsule increases the tendency; (5) pilocarp...

> of PCG. They include angle surgeries like goniotomy, trabeculotomy (manual, 3600 suture or microcatheter V ] | combined trabeculotomy with trabeculectomy with or without anti-metabolites; glaucoma drainage devices, and cyclodestructive procedures. Goniotomy, abexterno trabeculotomy, combined trabeculotomy with trabeculectomy with or without mitomycin C are the most commonly performed surgerie...

PURPOSE To describe the histopathology of non-valved implant capsules in three cases of persistent postoperative hypotony after the restrictive tube ligature was released in patients receiving immunosuppressive therapy. OBSERVATIONS The macroscopic appearance of the capsules 3 and 4 months postoperatively was immature and loose. Microscopic examination disclosed extremely irregular thin tissu...

BACKGROUND The existing approaches to the treatment of the atrophic maxilla are difficult and involve an element of risk. PURPOSE The aim of the present study was to establish a new surgical/prosthetic protocol for the treatment of extremely atrophic maxillae using four zygomatic implants (ZIs) in an immediate loading system. MATERIALS AND METHODS Twelve patients were treated with the surgi...
