Results and safety profile of trainee cataract surgeons in a community setting in East Africa.

Purpose: To evaluate the results and safety profile of assistant medical officer ophthalmologists (AMO-O) performing cataract surgery in the last stage of their surgical training, before their appointment to local communities.

Methods: We retrospectively analyzed the records of patients who underwent cataract surgery by AMO-Os at Dar es Salaam, Comprehensive Community Based Rehabilitation for Tanzania Disability Hospital between September 2008 and June 2011. Surgical options were either extracapsular cataract extraction (ECCE) or manual small incision cataract surgery (MSICS), both with polymethylmethacrylate intraocular lens implantation.

Misdirected aqueous flow in rhegmatogenous retinal detachment: a pathophysiology update.

It is widely accepted that the origin of subretinal fluid in rhegmatogenous retinal detachment (RRD) is liquid vitreous and that posterior vitreous detachment (PVD) and associated retinal tears are caused by vitreoretinal traction from intra-ocular currents, contraction of collagen fibers, and gravity. These explanations, however, are incomplete. We present a new synthesis of experimental and clinical evidence, updating understanding of fundamental pathophysiological processes in RRD.

Corneal collagen cross-linking for ectasia after LASIK and photorefractive keratectomy: long-term results.

Purpose: To report the long-term results of corneal collagen cross-linking (CXL) in ectasia after LASIK and photorefractive keratectomy (PRK).

Design: Retrospective, interventional cases series.

Participants: Twenty-six eyes of 26 patients (18 male, 8 female) with postoperative ectasia after LASIK (23 eyes) and PRK (3 eyes) were included with a mean age of 35 ± 9 years at the time of treatment and a mean follow-up of 25 months (range, 12-62 months).

Phacolytic glaucoma: are there 2 forms?

We report a case of acute phacolytic glaucoma in which only protein was present in the anterior chamber without macrophages. We propose that this study represents a type of phacolytic glaucoma characterized by a hyperacute presentation caused by rapid leakage of degenerated lens proteins into the aqueous humor as opposed to a second type with a more gradual onset and with phacolytic macrophages in the aqueous humor resulting from an immunologic response to liquefied lens proteins. Thus, 2 forms, perhaps at ends of a spectrum of clinical manifestations of phacolytic glaucoma, may exist with distinct characteristics and pathophysiology.
