Glaucoma screenings were held at community gatherings including local fairs, senior citizen homes, places of worship, and in the lobby of medical offices. The screenings were conducted by trained non-physician medical personnel comprised medical students and medical assistants working under physician supervision. Participants’ intraocular pressure (IOP) and central corneal thickness (CCT) were measured in both eyes with a handheld tonometer and pachymeter, respectively. Participants then completed a comprehensive eye exam by an ophthalmologist to confirm glaucoma status. Statistical analysis was completed using MedCalc version 22.023 (MedCalc Software Ltd. Ostend, Belgium) with 95% confidence intervals.Results: Of the 823 study participants, 716 (mean age 62.9 ± 11.9 years) were eligible to participate and completed the comprehensive follow-up exam. 68% identified as Black, 6.7% identified as Hispanic/Latino, and 52.5% identified as female. The Laroche glaucoma calculator had a sensitivity of 93.5% (CI 89.1– 96.5%), specificity of 91.3% (CI 88.5– 93.6%), positive predictive value of 80.5% (CI 75.7– 84.6%), negative predictive value of 97.3% (CI 95.5– 98.4%) and accuracy of 91.9% (CI 89.6– 93.8%).Conclusion: The Laroche glaucoma calculator shows high sensitivity, specificity, positive predictive value, negative predictive value, and accuracy using affordable screening methods to determine glaucoma risk.Keywords: glaucoma risk calculator, affordable glaucoma screening, glaucoma screening tools, community-based glaucoma study, Laroche glaucoma calculator, eye screening |
