The authors report 168 cases of opacification of posterior capsule treated by Yag laser capsulotomy. They describe the operating technique, the results, the complications and the indications.

The authors report 4 cases of recurrent vitreous hemorrhage related to retinal breaks without detachment, bridged by a retinal vessel. Clinical and evolutive features of this type of breaks are emphasized according to a review of available literature. Fluoroscopic evaluation of vascular permeability appears as a promising prognostic tool. Management should be directed to the prevention of both retinal detachment and vitreous hemorrhage recurrence. Cryoapplication and scleral buckling is far more effective than photocoagulation.
A patient undergoing hemodialysis was treated intravenously with desferrioxamine (3 g) for an aluminum encephalopathy. He presented a sudden xanthopsia with visual loss. Fundus examination showed diffuse macular irregular pigmentary disturbances. We discuss current knowledge and possible pathogenesis of these observations published since 1983. Awareness of the side effects of desferrioxamine implies an ophthalmologic follow up similar as chloroquine.
The authors describe a new anaesthetic protocol for laboratory rabbits. The surgery consists in an extracapsular lens extraction with intraocular lens implantation in the bag. The anaesthetic protocol requires: an intravenous induction with ketamine (20.2 mg/kg +/- 5) and midazolam (0.65 mg/kg +/- 0.3) and after an oral endotracheal intubation with a simple method, and at last maintaining halothane anaesthesia with a concentration between 3 and 4%. 45 anaesthesia were performed: the average time of the anaesthesia was 77 min +/- 16. No rabbit died because of this anaesthesia. The anaesthesia was a success for the surgeon who could operate in the best working conditions.
Authors present two cases of typical macular "bull's eyes" other APS treatment with subnormal electric answer. They evocate the poor sensibility of the different methods used to detect and follow these patients and propose a more sensible, easier and test accepted test: static perimetry within the 12 central degrees, once or twice a year.
The authors report a case of ocular involvement by acute lymphoblastic leukemia, in a young woman. The initial symptom was a bilateral diminution of visual acuity. The examination revealed a bilateral aspect of serous detachment of neuro-epithelium. A literature review of macular manifestations of leukosis is envisaged.
The lack of interest about oculorespiratory reflex (ORR) in surgery and experimental studies is obvious. However the authors insist on the importance of its clinical traduction. The purpose of this study is to determinate an experimental model with titration of stimulus (pressure or traction) and therapeutic test. Our first Results prove the clinic entity of O.R.R. In first conclusion, we can insist on the importance of ventilatory assistance during squint surgery and on the monitoring of PE CO2 and Sa O2.
