Ko YC, Kuo CY, Kuang TM, et al. - Researchers conducted this cross-sectional community-based screening program to identify acute angle closure (AAC) risk following pharmacologic mydriasis and the factors influencing post-mydriatic intraocular pressure (IOP) in a population with a high prevalence of angle closure disease. A total of 460 people [mean age 77.8 ± 4.1 years] aged ≥ 72 years were recruited. According to multiple linear regression analysis, post-mydriatic IOP was independently linked to baseline IOP and factors suggestive of crowded anterior chamber based on gonioscopic findings and central or peripheral anterior chamber depth evaluation in conjunction with lens thickness. Post-mydriatic IOP should be assessed in phakic eyes with a crowded anterior chamber. With intervention to prevent AAC, post-mydriatic IOP spikes can be effectively blunted.
