Purpose Glaucoma is the second cause, after cataract, of world blindness. Approximately half is thought to be primary angle-closure glaucoma (ACG). This review asks whether ACG can be prevented on a population basis. Methods and populations Review of published information from the Inuit of Greenland, Canada and Alaska, and descriptions of recent studies in Asian populations in Mongolia, China and SouthEast Asia. Results The Greenland Inuit have the shallowest anterior chamber depths (ACDs) so far recorded. The proportion of blindness due to ACG was reduced from 64% to 9% over 37 years by systematic optical measurement of central ACD and the van Herick test in the older Inuit, followed by gonioscopy and prophylactic iridectomy or laser iridotomy when indicated. In Mongolia, ultrasound measurement of central ACD had good sensitivity and specificity as a screening test. A randomized controlled trial of screening and prophylactic laser is being completed. In China and South-East Asia, the mechanism of angle closure appears to be more varied and complex and its detection may require more elaborate imaging. Conclusions The mechanism of angle closure and potential for prevention by screening are likely to have to be determined specifically for each population at risk.

Background: Acute closure of the anterior chamber angle can have catastrophic consequences for vision when it occurs in an unsupervised situation. Visual debilitation is much less likely to result when angle-closure occurs in a well-controlled environment that allows appropriate management. Therefore, it is desirable for optometrists to undertake a complete ocular health assessment, including mydriatic fundus examination, on patients who have narrow anterior chamber angles, provided that appropriate precautions and procedures are followed. Case report: We report on the case of a 59-year-old white female whose anterior chamber angles closed in response to mydriatic drops instilled during an optometric examination. Her optic discs and visual field results from before and four years after the angle-closure attack do not show any significant changes. Conclusion: We conclude that the optimal standard of care for patients presenting to an optometric practice, and who are subsequently found to have narrow anterior chamber angles, includes pupillary dilatation to allow stereoscopic visualisation of the optic nerve head. Precautions must be followed to ensure that, in the unlikely event of an ensuing angle-closure episode, the attack occurs under clinically supervised conditions.
