[Proliferative diabetic retinopathy: laser photocoagulation treatment].

Laser panretinal photocoagulation has proven its efficacy in controlling proliferative diabetic retinopathy. It is unclear exactly how photocoagulation works: several mechanisms are evoked, involving the pigment epithelium, the photoreceptors and the retinal microvascularization. Indications for treatment and the way of carrying it out are reviewed. Possible complications related with photocoagulation can occur. Some advanced or complicated forms of proliferative diabetic retinopathy need alternative treatments like cryotherapy or vitreoretinal surgery.

[Posterior scleritis: apropos of 6 cases].

In a retrospective study of 6 patients (9 eyes) with posterior scleritis, we analyse the symptoms, the clinical signs and the ancillary tests of the disease. A decreased vision and an ocular or periocular pain are found in 8 cases of 9. Anterior involvement like redness is found in all the cases. In 7 eyes, we observe a diffuse or localized exudative retinal detachment. B-scan ultrasonography is the most helpful ancillary test, showing in all the examined eyes a scleral thickening. In 2 patients, we find a systemic disease associated with the posterior scleritis.

[Occlusion of the central retinal vein in young adults: risk factors and visual prognosis].

Retrospective study of 15 cases of central retinal vein occlusion in young patients. A research for risk factors was performed. 4 patients had a systemic disease, and 6 had thrombophilic hematological conditions like blood hyperviscosity and increased platelet aggregation. No inflammatory disease was found. The visual prognosis was good in 7 out of 12 patients with a follow-up of more than 3 months. Chronic macular edema and neovascular glaucoma were responsible for the bad visual prognosis in 5 cases.

Fundus changes in membranoproliferative glomerulonephritis type II. A fluorescein angiographic study of 23 patients.

A total of 23 patients aged between 11 and 64 years who had biopsy-proven membranoproliferative glomerulonephritis type II (dense deposit disease) were studied using fluorescein angiography of the retina. With the exception of two adolescents, all patients exhibited small subretinal nodules that were similar to basal laminar drusen. Subjects with a long history of renal disease displayed more numerous and larger nodules as well as atrophic changes. Four subjects presented with subretinal neovascular membranes.

Purtscher-like retinopathy after retrobulbar anesthesia.

A Purtscher-like retinopathy occurred in a 41-year-old woman who underwent the excision of a pterygium after a retrobulbar injection of 3 ml of lidocaine HCl. Visual acuity increased from 20/200 on the first postoperative day to 20/25, 12 weeks later. The exudates and the hemorrhages progressively disappeared. However, a relative, localized, paracentral scotoma and an afferent pupil defect still persist. The pathophysiology of this Purtscher-like retinopathy is discussed.

Retinal and choroidal vaso-occlusive disease in systemic lupus erythematosus associated with antiphospholipid antibodies.

Three patients with systemic lupus erythematosus (SLE) associated with anti-phospholipid antibodies are reported. All three had severe vaso-occlusive disease: the first had an unilateral vaso-occlusive retinopathy, the second an unilateral central retinal venous obstruction, and the third a bilateral ischemic choroidopathy. The association of these occlusive ocular vascular diseases with the presence of the lupus anticoagulant and other associated factors in SLE is discussed.

[Syphilitic uveitis. Apropos of 2 cases].

Report of two cases of syphilitic uveitis which presented vasculitis, papillitis, cystoid macular edema and large disturbance of the pigment epithelium. The superior value of the FTA-Abs test and of the cerebrospinal fluid analysis in the diagnosis of the disease is discussed. Treatment with high doses of Penicillin G for 10 to 15 days is recommended.

[Central serous choroiditis following renal transplantation].

Report of 5 cases of central serous choroidopathy (CSC) following kidney transplantation. The authors compare the clinical features, the fluorescein angiography, the color vision, the visual field and the electrophysiological tests of these 5 cases with 7 control patients. In the pathogenesis of the CSC, the authors briefly discuss about the risk factors associated with the transplantation.

Sequential observation of fundus changes in patients with long standing membranoproliferative glomerulonephritis type II (MPGN type II).

Specific fundus changes have been reported in patients with membranoproliferative glomerulonephritis type II (MPGN type II). We studied the clinical course of this retinopathy in four patients who all had a long follow-up with several fundus examinations. Sequential observation was indicative of a slow progression of the retinopathy. Most eyes maintained in the chronic stages a nearly normal visual acuity, and a full visual field despite the existence of marked drusen and atrophic changes. The prognosis however must be somewhat guarded, since choroidal neovascularization developed in three eyes and caused bilateral severe visual loss in one patient.

Bilateral optic neuropathy associated with the crest variant of scleroderma.

We report a case of bilateral optic neuropathy associated with the CREST syndrome, a variant of scleroderma. Immunosuppressive therapy achieved significant improvement of the visual symptoms for two years. The pathophysiological mechanisms underlying this unique association remain unclear.
