Purpose: To compare the prevalence of angle closure disease (ACD) diagnoses in a glaucoma department of an ophthalmology teaching hospital at two cut points, before and after encouragement of a supervised, mandatory gonioscopy for all patients, during all visits as well as to profile patients with angle closure disease in terms of age, gender, intraocular pressure, visual acuity, cup-to-disc ratio and refractive error parameters when divided by Foster's classification. Study design: Retrospective, two cut-point observational study. Material and methods: A 1-month sample of electronic medical records from 2010 and from 2013 was analyzed. Between those two cut points, gonioscopy was encouraged as a mandatory procedure and execution was supervised systematically. The prevalence of angle closure disease was obtained from the diagnosis of electronic medical records and patients with ACD were divided according to Foster's ACD classification in order to profile them. Results: A total of 2112 medical records from 2010 and 2549 medical records from 2013 were included. Angle closure disease prevalence went from 7.29% (n=154) in 2010 to 20.36% (n=519) in 2013. Prevalence of primary open angle glaucoma (POAG) decreased from 23.20% to 10.84% in the same time period. Conclusions: A comparison between the prevalence of angle closure disease between these two cut points showed a considerable increase. Angle closure disease was diagnosed 1.79 times more as opposed to when gonioscopy was not previously encouraged or supervised. ACD patients are generally women, with decreasing low hyperopia and intraocular pressure within normal ranges.
