METHODS: From November 2013 to January 2015, 33 amblyopic patients with high myopic anisometropic amblyopia were studied. FS-LASIK(30 eyes) or SMILE(3 eyes) was performed in the amblyopic eyes. Visual acuity, refraction, contrast sensitivity, stereoacuity and complications were evaluated. Patients completed followup examinations at 3 d, 1 mo, 3 mo and the last follow-up time(mean 8.17±3.23 mo) after surgery. RESULTS: The mean age at surgery was 9.04±3.04 y(range 6-16 y). The mean spherical equivalent in the amblyopic eyes was significantly decreased from-10.00±2.39 D preoperatively to-0.06±1.06 D at 1 mo,-0.19±1.33 D at 3 mo and-0.60±1.43 D at approximately 8 mo postoperatively(P〈0.05 for all). The mean myopic anisometropia was significantly decreased from-9.45±2.33 D preoperatively to +0.37±1.48 D at 1 mo,-0.46±1.47 D at 3 mo and-0.09±1.83 D at approximately 8 mo(P〈0.05 for all). The logarithm of the minimum angle of resolution(log MAR) for uncorrected and corrected distance visual acuity(UDVA and CDVA, respectively) of the amblyopic eye improved from 1.74±0.35 and 0.98±0.63 preoperatively to 0.45±0.31 and 0.41±0.33 at approximately 8 mo after surgery, respectively. The logM AR CDVA at 3 d, 1, 3 and 8 mo postoperatively improved by means of 1.42, 2.22, 2.96, and 4.39 lines, and a gain of more than two lines accounted for 45%, 50%, 74% and 86% of all patients, respectively. The contrast sensitivity of both amblyopic eyes and dominant eyes at 0.5, 2, 8 cycles perdegree was significantly improved postoperatively(P〈0.05 for all). Of the 33 pediatric patients, no patients had near stereopsis preoperatively and seven patients(21.2%) recovered near stereopsis(400″ to 60″) at approximately 8 mo after surgery. No intraoperative or postoperative complications occurred in any patient.CONCLUSION: FS-LASIK or SMILE can be promising alternative methods to correct high myopic anisometropic amblyopia in juvenile patients who have failed with traditional approaches.展开更多

This study was aimed to determine the frequency and patterns of URE across 4 gradients of residential densities(urban, exurban, suburban and rural). This was a cross-sectional study of school children from 3 districts in Yogyakarta and 1 district near Yogyakarta, Indonesia. The information regarding age, sex, school and school grader were recorded. The Snellen's chart was used to measure the visual acuity and to perform the subjective refraction. The district was then divided into urban, suburban, exurban and rural area based on their location and population. In total, 410 school children were included in the analyses(urban=79, exurban=73, suburban=160 and rural=98 school children). Urban school children revealed the worst visual acuity(P〈0.001) and it was significant when compared with exurban and rural. The proportion of URE among urban, suburban, exurban and rural area were 10.1%, 12.3%, 3.8%, and 1%, respectively, and it was significant when compared to the proportion of ametropia and corrected refractive error across residential densities(P=0.003). The risk of URE development in urban, suburban, exurban, and rural were 2.218(95%CI: 0.914-5.385), 3.019(95%CI: 1.266-7.197), 0.502(95%CI: 0.195-1.293), and 0.130(95%CI:0.017-0.972), respectively. Urban school children showed the worst visual acuity. The school children in urban and suburban residential area had 2 and 3 times higher risk of developing the URE.展开更多
