[Cataract surgery and implantation in diabetics. Apropos of 92 eyes].

We examined 92 eyes (63 patients) who underwent extracapsular cataract extraction with implantation of a posterior chamber intraocular lens. Visual acuity improved by two lines or more in 65% of cases. Follow-up examination (6 months and 2 years) showed posterior capsule opacification in 30% of cases. Progression of diabetic retinopathy was mild but cystoid macular edema was present in 70% of cases with non proliferative retinopathy. Proliferative retinopathy was treated postoperative by pan retinal photocoagulation. One neovascular glaucoma occurred, secondary to a ruptured capsule.

[Bouchut's tubercles. A clinical and angiographic study].

Four patients (3 young adults and 1 child) with disseminated tuberculosis had choroidal tubercles; none of them was immunodepressed. The clinical and angiographic aspects of these nodules and their evolution are described. Their clinical interest is discussed: fundus examination is always indicated in cases of disseminated tuberculosis and, more generally, in cases of systemic granulomatosis.

[Retinopathy in pancreatitis].

Three patients with retinopathy associated with acute pancreatitis were observed. Each of them had a long history of alcohol abuse. The first patient was asymptomatic. Second one developed moderate visual loss in one eye (visual acuity 20/40), with a fascicular defect on Goldmann visual field registration. Third patient complained with bilateral and severe visual loss, with a large central scotoma. Cotton-wool patches and hemorrhages were present in the mild types of retinopathy. These cases had a good prognosis. An ischemic edema of posterior pole was associated in severe type of retinopathy. In this case, fluorescein angiography showed occluded macular retinal arterioles. Visual prognosis was poor. Pathogenesis of the lesions is still discussed. The main hypothesis are fat emboli or activated complement-induced granulocyte embolus formation. Efficacity of corticosteroids is not known.

[Hypertensive retinopathy and papilledema. Apropos of a case of glycyrrhizin poisoning].

We present a case report of a patient suffering of severe hypertension and grade IV hypertensive retinopathy according to the Keith-Wagener classification. Simultaneously hypertensive encephalopathy was present confirming the poor prognosis of discoedema occurring in the course of hypertension when left untreated. Hypertension was related to chronic poisoning with glycyrrhiza, and its hyperaldosteronism like effect. Pathogenesis of discoedema in malignant hypertension is discussed.
