Prospective randomized trial: outcomes of SF₆ versus C₃F₈ in macular hole surgery.

Objective: To compare macular hole (MH) closure and visual acuity improvement after vitrectomy using SF6 versus C3F8 gas tamponade. The secondary purposes were to report the cumulative incidence of cataract development at 1 year after MH surgery and the proportion of complications.

Design: Prospective, randomized study.

Retinal function assessment of trypan blue versus indocyanine green assisted internal limiting membrane peeling during macular hole surgery.

Objective: To compare multifocal electroretinography (mfERG) retinal function and the anatomical and visual outcomes of macular hole surgery performed with indocyanine green (ICG) or trypan blue (TB).

Design: Prospective, randomized study.

Participants: Twenty-five eyes of 24 patients.

Bevacizumab and ranibizumab for neovascular age-related macular degeneration: a treatment approach based on individual patient needs.

Objective: To compare the efficacy of intravitreal bevacizumab and ranibizumab for the treatment of neovascular age-related macular degeneration using an as-needed treatment regimen.

Design: Retrospective chart review.

Participants: One hundred and ninety two eyes of 184 patients.

[The role of cryo-application in certain types of exudative retinal detachment].

The authors describe a patient with exudative retinal detachment who presented characteristics of uveal effusion syndrome and of idiopathic central serous choroidopathy. The causes and current approaches to treatment are discussed.

Association of varicella zoster dermatitis with acute retinal necrosis syndrome.

The authors report seven patients in whom the acute retinal necrosis (ARN) syndrome developed shortly after cutaneous varicella zoster infection. The length of time between the skin infection and ARN varied from 5 days to 3 months. Both eyes were affected in one of seven cases.

[Retinopathy due to canthazanthine: 2. Predisposing factors].

A retrospective study of 14 cases of retinopathy due to canthaxanthine, a carotenoid recently used as a skin-tanning agent, revealed that several clinical factors were associated with an increased susceptibility to retinal deposits: focal epitheliopathy, ocular hypertension and, possibly, the concurrent use of beta-carotene. Age has already been established as such a factor.

[Canthaxanthine retinopathy: 1. Clinical study in 51 consumers].

Canthaxanthine, a non-provitamin A carotenoid, has been marketed in Canada since March 1979 as a skin-tanning agent. Fifty-one individuals who ingested from 3.6 to 66 g of the drug within a 24-month period were ophthalmologically evaluated.

[Maculopathy with golden particles].

This article describes two patients with a bilateral maculopathy due to the presence of numerous glistening yellow particles located mainly around the edge of the macular pit. This picture has apparently not been reported before. Further studies are needed to confirm a possibly toxic origin.

[Role of photocoagulation in central serous choroidopathy].

We reviewed thirty-two cases of central serous choroidopathy and retained twenty-five for a twelve-month study of the natural history of this disease. The main conclusions are that the disease is benign and self-limited; it sometimes leaves sequelae such as subnormal visual acuity because of faveolar leak through Bruch's membrane; photocoagulation is useful only in a minority of cases.

Closed vitreous surgery: XV. Fibrovascular ingrowth from the pars plana sclerotomy.

Ten eyes developed fibrovascular ingrowth from the sclerotomy following closed vitreous surgery. The complication was detected by examining all patients postoperatively by indirect ophthalmoscopy and biomicroscopy with a three-mirror lens. The average follow-up was 13.

Vitreous surgery. XIV. Complications from sclerotomy in 89 consecutive cases.

All patients were examined preoperatively and postoperatively by indirect ophthalmoscopy and biomicroscopy with a three-mirror lens. The average follow-up was eight months. Our technique of sclerotomy consisted of an incision parallel to the limbus, measuring 1.
