Fig 2. Comparison of treatment modalities between patients with APAC in 2007 and 2017. In 2007, of 49 patients, 25 patients (51.02%) underwent LPI only, 18 patients (36.73%) required further LE, and 6 patients (12.24%) required further trabeculectomy. However, in 2017, of 60 patients, only 23 patients (38.33%) underwent LPI, with 29 (48.33%) and 8 (13.33%) patients received LE and trabeculectomy, respectively, for the treatment of APAC (P= 0.015). APAC = acute primary angle closure; LE = lens extraction; LPI = laser peripheral iridotomy.
