英文摘要 | We investigated the biometric characteristics of acute primary angle-closure glaucoma (PACG) patients and sought guidelines to predict subjects at high risk of acute attack. We enrolled 80 patients who suffered acute attack of angle-closure glaucoma and 60 nonglaucoma subjects. The biometric data, measured with A scan ultrasonography, and the outcomes after various treatments were analyzed. Six patients were excluded because they were lost to follow-up. In the acute PACG patients, the axial length (mean ± standard deviation) was 22.25 ± 0.77mm, the anterior chamber depth (corneal thickness included) was 2.28 ± 0.23 mm, and the lens thickness was 4.94 ± 0.28 mm. In the nonglaucoma subjects, the axial length was 23.26 ± 0.76 mm, the anterior chamber depth (corneal thickness included) was 3.11 ± 0.25 mm, and the lens thickness was 4.48±0.30 mm. An anterior chamber depth of less than 2.70mm was the most sensitive (94%) and specific (94%) parameter to differentiate acute PACG patients from nonglaucoma subjects. The intraocular pressure was controlled within the satisfactory range in 58 patients by laser iridectomy, with or without antiglaucoma medication. Eight patients needed additional gonioplasty and eight required filtering surgery to control the intraocular pressure. Our findings provide useful information about the biometric data of eyes of patients with acute angle-closure glaucoma and offer a useful guide to predict those patients at high risk of acute attack.. |
