Update on sympathetic ophthalmia.

Sympathetic ophthalmia (SO) is a bilateral diffuse granulomatous intraocular inflammation that occurs in most cases within days or months after surgery or penetrating trauma to one eye. The incidence of SO ranges from 0.2 to 0.

Perfluorocarbon-perfused vitrectomy: a new method for vitrectomy--a safety and feasibility study.

Purpose: To evaluate the safety and feasibility of perfluorocarbon-perfused vitrectomy (PCPV) as a technique during vitrectomy for proliferative diabetic retinopathy (PDR) and rhegmatogenous retinal detachment (RRD).

Methods: In an experimental, prospective, noncomparative and interventional study, 28 eyes of 28 patients were submitted to vitrectomy with the PCPV technique, 18 eyes with PDR and 10 with RRD. In this technique we replaced the traditional balanced saline solution (BSS) in the infusion line (conventional vitrectomy) by perfluorocarbon liquids (PCL).

Vitrectomy with complete posterior hyaloid removal for ischemic central retinal vein occlusion: series of cases.

Background: Central retinal vein occlusion (CRVO) is a common retinal vascular disorder with potentially complications: (1) persistent macular edema and (2) neovascular glaucoma. No safe treatment exists that promotes the return of lost vision. Eyes with CRVO may be predisposed to vitreous degeneration.

[Phacoemulsification cataract surgery in vitrectomized eyes].

Objective: This study focuses on determining the intra- and post-operative complications stemming from technical difficulties, anatomical aspects, intraoperatory management and visual outcome of post-vitrectomized patients that undergo phacoemulsification.

Method: In this prospective, longitudinal, observational and descriptive study phacoemulsification was performed in 25 post-vitrectomized eyes that required cataract surgery. Pre-surgical variables: sex, age, affected eye, visual accuity, underlying vitreoretinal disease, anterior segment morphological findings such as: cataract density and pupil alterations.

Perfluorocarbon perfused vitrectomy: animal studies.

Purpose: To investigate the feasibility and advantages of using perfluorocarbon liquid (PCL) perfusion to remove vitreous during suction-cutting vitrectomy in rabbit and pig eyes.

Design: Experimental study.

Methods: Balanced salt solution (BSS) was replaced by PCL perfusion during experimental vitrectomy.
