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.

Radial optic neurotomy for ischaemic central vein occlusion.

Background/aims: Ischaemic central retinal vein occlusion (CRVO) accounts for 20-50% of all CRVO. No treatment has been proved to be effective. The efficacy of radial optic neurotomy (RON) was evaluated in eyes with ischaemic CRVO.

[Bilateral macular cysts secondary to electric current strike. A case report].

Objective: To report the clinical and tomographic findings in a case of maculopathy secondary to high-tension electric current strike.

Case Report: A 27-year-old male refers a reduction in his visual acuity after electric strike. Visual acuity was 0.
