Retinal breaks secondary to vascular accidents.

Seven retinal breaks occuring after occlusion of a major retinal arterial or venous branch were found in the eyes of six patients. Five holes were in the midretina, in a nonperfused avascular area corresponding to the sector affected by the vascular accident. One was a macular hole, and one a horseshoe tear outside the area involved in the vascular occlusion caused by traction of vitreous on a tuft of neovascular tissue. Five of the holes may have been caused by a kind of sequestration of the retina secondary to vascular insufficiency.

[Collateral circulations and new vessels in retinal branch vein occlusions. II. New vessels (author's transl)].

Two types of anastomotic new vessels develop after retinal branch vein occlusions. In a previous article (Arch. Ophtal. (Paris), 1977, 8-9, pp. 507-522) the useful collateral vessels were described in the re-establishment of a better circulation in the territory of the occluded vein. The second part discusses new vessels: they are dangerous and useless. Their pathogenesis poses the problem of the relationship between hypoxia, ischaemia, revascularisation and vasoproliferation. Their prevention and treatment calls for laser photocoagulation of the ischaemic territory.

[Pan-retinal argon laser-photocoagulation in retinopathia diabetica. First results (author's transl)].

The apparition of diabetic retinopathy depends on the duration of the evolution of the diabetes and its control, and its type. The indications for photocoagulation are in progressive retinopathy the existence of macular edema or retinal or prepapillar neovascularisation. The pan-rtinal argon laser photocoagulation is the best technic for treatment. It leads to a global improvement whose results are presented, after 2 years follow-up.

[Surgical treatment of retinal detachment without drainage: apropos of 100 consecutive cases].

Recent advances in retinal detachment surgery must end in a simplification of the techniques: cryo-applications associated with a scleral buckling by one or more Lincoff sponges parallel to the equator seems to be satisfactory in almost all cases. Subretinal drainage, whatever technique used, does not seem to ameliorate significantly the evolution which depends, essentially, on the indentation and localisation quality. Furthermore, scleral perforation seemed to caused supplementary complications in an important number of cases. Analytical review of 100 consecutive cases.
