Xéroderma pigmentosum (XP) is a rare genetic disease characterised by defective repair of DNA damage. We report a retrospective study of the ophtalmologic manifestations of 16 patients with xéroderma pigmentosum, the ophtalmologic manifestations were present in 62% of cases. The age of patients was 7 to 22 years. Photophobia were seen in all patients. Multiple tumors were seen with 5 squamous cell carcinoma. Tumor size was 1 to 6 cm. Ocular involvement occurs in up to 80% of cases of XP. Infection, néoplasia, conjonctiva are the most commun finding...

Using the transmission electron microscope and the scanning electron microscope, we have found a different ultrastructure at the different levels of the lacrimal system: 1) tarsal conjonctiva: numerous microvilli on a relief of small valleys; 2) lacrimal punctum: the surface of the cell is flat with sparse microvillosti, sparse cilia and strong intercellular junction; 3) external part of the canaliculus: pavement epithelium with numerous microvillositi and pinocytosis, absence of cilia; 4) internal part of the canaliculus: the microvillositi are very small or absent; 5) lacrimal sac: the cilia are arranged by tufts scattered on this malpighian epithelium; 6) nasolacrimal duct: the cilia are numerous; 7) in the nose the cilia are extremely numerous...

The Haik fornix conjonctival flap has been described before the second world war, in order to protect cornea with conjonctiva without cutting the latter as in the classic conjonctival flap. This operation requires only a limited number of instruments and no special ophtalmologic training for the operator. The main indications are: -- keratitis caused by lagophtalmia; -- neurophtalmic keratitis; -- ulcerous keratitis and specially the meta-herpetic ones; -- necessity of a protection before a sanitary evacuation in penetrating wounds of the ocular globe...

250 leprous from National Leprosery of Manankavaly (distant of 30 km from Tananarive) were examined. Among them, 31 patients present ocular disease which occur with that of leper isn't accurately known. Conjuntival reactions as prickling, watering of the eyes with inability to assimilate wind light constitute initial symptoms. Cataract is exceptional (only one case); but we point out; first the superiority of "uveal tractus" disease with 32% of rate; then, the frequency of deep of interstitial keratitis (35%)...

A case of bilateral congenital oculodermal melanocytosis is reported. Ota's naevus is characterized by benign melanosis of the skin of the face in the area supplied by the first (and second) branch of the trigeminal nerve. This is associated with ipsilateral pigmentation of the episclera++, uveal tract, conjonctiva and fundus. The condition is usually unilateral, occurring mainly in the dark races (black races and orientals). Eighty percent of patients are women. It is very rarely potentially malignant, this occurring most frequently in white races and when only ocular (and not oculodermal) melanocytosis is present...

The toxicity of human interferon alpha 2b in rabbit's vitreous and conjonctiva is studied through electroretinography, echography, angiography and histological examination. Interferon was injected in increasing doses 150,000 UI, 500,000 UI and 1,000,000 UI. The results from examinations in the rabbits are presented and the conclusion is drawn, that good tolerance is achieved, even at higher doses.

A comparative study of 11 antibrucellic vaccines has been carried out in the Limousin region of 360 ewe-lambs divided into groups of 30, a 12th group serving as control. After being vaccinated at 8 months, the ewe-lambs were covered between 9 1/2 and 10 1/2 months, then infected at 11 months with Br. melitensis strain 53 H 38 by instillation of 4 x 10(6) germs on the conjonctiva. Six of these vaccines reduced the number of abortions and the excretion of brucella at parturition: three consisted of an inactivated suspension of a virulent S strain of Br...
