Prevalence of eye disease and visual impairment in Île de la Gonave, Haïti.

Epidemiological data describing the prevalence of blindness and visual impairment in Haiti are sparse. The Haitian National Committee for the Prevention of Blindness (CNPC) estimates the prevalence of blindness at 1 %. Other regional data estimate moderate and severe visual impairment at 5% and 22%, respectively. IRIS Mundial (IM) is a non-governmental organization collaborating with the CNPC to develop eye care infrastructure in Haiti. To estimate the prevalence and causes of blindness and visual impairment on the Haitian island of Gonâve, to assist in planning of relevant eye care infrastructure. Results from eye exams carried out by a team from IM in January 2013 have been compiled and analyzed. In all, 1724 patients were examined (38% men, 62% women). In the best eye, 87% of patients had visual acuity, 6% had moderate visual impairment, and 7% had severe visual impairment. Moreover, 1% of patients had high myopia, 1% high hyperopia, 1% high astigmatism, and 32% were presbyopic. Clinically significant binocular cataracts were found in 1.5 % of patients, while 2 % were diagnosed with probable glaucoma. Our data give a glimpse of the prevalence of visual impairment and ocular disease on Gonâve Island in Haiti. Uncorrected refractive error, cataracts, and glaucoma are confirmed as prevalent conditions in this population and their presence should guide the planning of relevant eye care interventions.
