[Glaucoma screening in Martinique. Results in 813 hospital employees].
BACKGROUND
Several US and Jamaican studies have shown that glaucoma is more severe in black populations than in Caucasian populations, which would lead to the assumption that the people of Martinique have a high glaucoma risk.


METHODS
A prospective study was conducted in workers of Fort de France University Hospital with the occupational medicine unit. Intraocular pressure was measured with a pulse air tonometer (Topcon CT 60) and visual field abnormalities were detected with automated perimetry using Humphrey frequency doubling technology (FDT). Patients with known glaucoma or with intraocular pressure over 21 mmHg and/or a visual field abnormality were referred to ophthalmology examination to diagnose ocular hypertension, open-angle glaucoma or normal-pressure glaucoma.


RESULTS
The occupational medicine unit examined 813 workers. The sex ratio was 0.36, mean age was 45.35+/-8.4 years (22-64 years), and mean ocular pressure was 12.1+/-2.62 mmHg (6-28 mmHg). Roughly 20% of workers had a family history of glaucoma. We found 22 patients with glaucoma (2.7%) (CI95: 1.6%-4%): 12 patients had open-angle glaucoma (1.5%) and 10 patients were diagnosed with normal-pressure glaucoma (1.3%). Glaucoma prevalence increased with age, reaching 8% in patients over 55 years of age. Of patients with normal-pressure glaucoma, 42.9% had a family history of glaucoma.


CONCLUSIONS
Our results confirm previous data from the literature that found higher glaucoma prevalence in black people and in particular in the mixed-race population of Martinique. In addition to this ethnic feature, the insularity of Martinique could support glaucoma expression. Easy and fast to use, FDT associated with the pulse air tonometer provides early detection of glaucoma.
