49 eyes with pseudophakic retinal detachments are operated with 44 good anatomic results (90% success). These detachments are characterised by the high frequency of anterior proliferative vitreoretinopathy.

The authors study an observation of unusual localisation, near the optic disc, of periphlebitis associated to multilocular sclerosis. There are some cicatricial periphlebitis and active others, which are more peripheral, alone without any uveitis. These ones resolved in two months with cortisone treatment.

The anterior region of 16 medial rectus muscles has been studied using myosine. ATPase at pH 4.63. The authors find one third dark fibres type I like, ATPase positive and two thirds fibres type II like ATPase negative. Types II A, II B and II C are difficult to individualize.

90 diopters lens is very performing for indirect ophthalmoscopy in pseudophakic patients, for macular fine examination and to realise difficult laser photocoagulation (through gas or silicon). 90 D lens is also safer since it never touches the eye.

56 patients with primary retinal detachment were treated by pneumatic retinopexy. The overall success rate for reattachment with one operation was 66%. Postoperative complications included development of new tears (18%) and P.V.R. (16%). Pneumatic retinopexy is a valuable new technique, however careful patient selection and postoperative management is required.

The authors present 17 cases of perforating ocular injuries caused by fire arms. They successively describe circumstances of trauma, initial injuries, surgical techniques employed and their results. The mean follow-up of patients is about one year. They particularly insist on severity of this type of trauma and legislative problems caused by free sale of some of these arms, more specially so called self defence pellets guns.

Controlled vacuumed drainage of subretinal fluid is achieved using a 25 gauges butterfly needle and a syringe. This technique often totally flattens the retina during the operation. It seems particularly indicated in inferior retinal detachment without break.

Intraocular silicone oil tamponade is used as an adjunct to vitrectomy in the treatment of proliferative vitreoretinopathy. The authors analyzed the effect of silicone oil on the corneal endothelium in 28 patients (10 phakic and 18 aphakic). In the phakic group, the endothelial cellular loss is small, no significant. In the aphakic group, the endothelial cellular loss is 20%.

Uveal effusion syndrome is a rare entity. It associates a nonrhegmatogenous retinal detachment, an annular cilio-choroïdal detachment and peripheral vascular anomalies. It is important to differentiate it from the another retinal detachments and the malignant melanoma.
