ABSTRACT
Melanesian population amounts to 61,270 out of 145,368 inhabitants in New Caledonia according to the last census. Melanesians of phototype VI have no predisposition in regard to malignant melanoma. From 1977 to 1987, 7 cases have been reported. Localisations are always in some zones not exposed to sunlight: 3 acral-lentiginous melanoma of the sole, 2 tumorous nodules of the anus margin and the vulva, 2 choroidal localisations. So, incidence of cutaneous malignant melanoma is very low (0.7/100,000 per annum) and in accordance with classical data regarding black people. But one has to keep in mind its being in some characteristic localisations. All the above referred cases have been detected at an advanced local extension.

In developing countries, cataract affects many young but also poor patients. They have difficulties to get operated and generally cannot afford to buy spectacles. Implanting artificial crystalline lens is, then, theorically the best solution. This skillfull technique, nevertheless, requires a high level sanitary environment. Recent advances in the surgical treatment of cataract and postoperative correction of aphakia minimized its risks. Improvements in plastics technology give new possibilities. A study of the various techniques available and of the changes required in the sanitary environment of developing countries give some hope for a possibility of using artificial crystalline lens in these countries.

A case of a trachoma at scar-stage with entropion-trichiasis is recorded. The patient was a white woman having spent her whole life in Saint-Pierre and Miquelon Islands which are not affected by trachoma. The authors, then, review the present trends about the extraocular and ocular diseases caused by Chlamydia trachomatis.

The authors report a case of pure macular oedema. After ruling out all other etiologies, the diagnosis of schistosomiasis due to Schistosoma mansoni was established, with parasitologic and serologic proofs. The specific treatment was followed up by a progressive restoration associated with an acute increase of eosinophila. The question of ocular damages in schistosomiasis is exposed according to the existant litterature: 1) Presence of schistosoma eggs in the ocular area. 2) Presence of adult schistosome in the eyeball. 3) Ocular troubles assumed to be in relation with the presence of adult worm or to larva.

The authors give a study about retinopathy by 4-amino-quinoleine in malaria prevention. Twelve observations are known in patients after 12 to 20 years of treatment. The authors suggest systematic research of this retinopathy.
