To determine the incidence of glaucoma suspects in the Afro-Caribbean population of South Florida at community screenings.
This is a retrospective chart review from October 2011 to October 2013. A total of 939 unique patient charts were reviewed from 5 separate health screenings held at the Center for Haitian Studies within the Little Haiti district in Miami, Florida. Measurements of intraocular eye pressure (IOP), cup-to-disc ratio, and visual acuity (VA) were performed on all patients. Glaucoma suspects were defined as having either an IOP of 24 mm Hg or greater or a cup-to-disc ratio of 0.6 or greater in either eye. The incidence of glaucoma suspects was calculated as well as the severity of pathology based upon IOP, cup-to-disc ratio, and visual acuity.
During 2011-2013, a total of 331 patients were newly identified as glaucoma suspects in the Afro-Caribbean community of South Florida during community screenings. The incidence of a glaucoma suspect diagnosis was 35.3%. Among patients diagnosed as glaucoma suspects, the median IOP was 22.0 mmHg (SD 19-25), the median cup-to-disc ratio was 0.60 (SD 0.4-0.8), and the median logMAR VA was 0.22 (SD 0.20-0.24, Snellen equivalent 20/30). Overall, the median age of patients diagnosed as glaucoma suspects was 56 years.
Community health screenings alone have led to an increase in the number of people diagnosed with glaucoma. The incidence and severity of optic nerve cupping and ocular hypertension in the Afro-Caribbean population of South Florida is very high even though the median visual acuity of these patients is close to normal. Our experience in the clinic shows that patients with glaucoma from the Haitian population are among the highest with the greatest level of blindness at the youngest ages. The data from these community screenings suggests the Afro-Caribbean population is a high-risk population for glaucoma in line with our impression in our clinics. Further follow-up will determine the incidence and severity of glaucoma.
