RESUMO
The unprecedented partnership for onchocerciasis control that followed Merck's decision to donate Mectizan has inspired the formation of a global initiative for the elimination of all avoidable blindness by the year 2020. 'Vision 2020, the Right to Sight', jointly co-ordinated by the World Health Organization's Programme for the Prevention of Blindness and Deafness and the International Agency for the Prevention of Blindness, was launched in 1999. This initiative's three pillars are disease control, human resource development, and infrastructure development. Vision 2020's achievements to date include the growth of the partnership, to include more than 60 member organizations, the revitalization of prevention activities, the completion of Vision-2020 plans in 40% of all countries and a reduction not only of blindness caused by onchocerciasis but also of blindness caused by trachoma. Cataract remains the leading cause of avoidable blindness.

The authors report three cases of conjunctival rhinosporidiosis from Zaire, two of which are believed to be the first documented in the northeastern part of the country. All patients were males. Two patients were very young children, respectively 5 and 6 years old. The third patient was a 35-year-old man. The diagnosis was based on histopathology which revealed the characteristic features of Rhinosporidium seeberi. Total excision was the elective treatment. The disease recurred eleven months later in one case, probably from local dissemination of the parasite during surgery.

Eight cases of ocular ulcerative herpes following measles are reported. The clinical features are characterized by dendritic corneal ulcer (6 cases) and ulcero-erosive blepharitis associated with corneal ulcer (2 cases). Bacteriologic examination disclosed Pseudomonas aeruginosas in 2 cases. The serum level of retinol, RBP, prealbumin and albumin were generally diminished in cases of dendritic corneal ulcer. These data are discussed in relation to the onset and severity of ocular ulcerative herpes associated with measles.
