Abstract

PURPOSE
To analyze the affecting factor of lens in pathogenesis of acute primary angle-closure glaucoma (APACG) and the effect of selected cataract extraction with intraocular lens (IOL) implantation. METHODS: A survey was conducted on 25 eyes of 21 patients with acute angle-closure glaucoma accompanied by senile cataract against 21 eyes of 16 age-matched normal persons. Biometric measurements were made in both groups in order to analyze an affecting factor of lens in APACG. Before and after selected cataract extraction, other clinical findings were also evaluated. RESULTS: Biometric measurements such as anterior chamber depth (ACD), lens thickness (LT), ACD/axial length (AXL), LT/AXL, and relative lens position (RLP) were significantly larger for the 25 eyes of the 21 patients with APACG than the 21 eyes of the 16 age-matched normal persons (P<0.05). After selecting cataract extraction with IOL implantation, improved biometric measurements and clinical findings revealed the effectiveness of that operation. CONCLUSIONS: Selected cataract extraction with IOL implantation could be successful as primary surgery in APACG accompanied by senile cataract over intraocular pressure control and visual acuity improvement for lens factor removal of APACG.
