| Popis: | Purpose The aim of this study was to evaluate the biometric characteristics of Egyptian patients with history of acute angle-closure crisis (AACC). Patients and methods This is a retrospective case–control study that included 20 patients aged 18 years and older. They were divided into three groups: group 1, which included 10 patients who had history of AACC in one eye; group 2, which included the fellow eyes of the patients with AACC who served as control eyes; and group 3, which included 10 normal volunteers participating with one eye as normal controls. Biometric parameters of the eyes were acquired and the ocular crowding value (OCV − defined as lens thickness+central corneal thickness − anterior chamber depth/axial length) was calculated for each eye. Receiver operating characteristic curves were plotted, and biometric variables were compared to compile a risk assessment for AACC. Results There was a statistically significant difference in the OCV between the different eye groups. The OCV had a 90.0% sensitivity and 75.0% specificity at a cutoff value above 0.1045. Eyes with AACC had significantly thicker lens (P=0.008), shallower anterior chamber depth (P |
