Scheimpflug Imaging Criteria for Identifying Eyes at High Risk of Acute Angle Closure

To compare anterior segment and ocular biometric parameters in unaffected fellow eyes of patients with a previous attack of acute angle closure (AAC), primary angle closure suspect (PACS) eyes, and normal eyes; and to identify eyes at high risk of AAC among primary angle closure suspects. In this case-control study, 16 unaffected fellow eyes of patients with a previous attack of AAC (group I), 20 PACS eyes (group II) and 18 normal eyes (group III) underwent Pentaca and A-scan echography. Mean anterior chamber volume was 72±18, 77±18 and 176±44? l in groups I, II, and III, respectively (P)
