ical retinal reattachment in 6 months post-opera-tive and 6 months postoperative BCVA.Statistical AnalysisTravel distance to the referral hospital (TDH) was classified into 5 groups, less than or equal to 30 km, 31-60 km, 61-90 km, 91-120 km, and more than 120 km. SO-C was categorized into 5 groups, less than or equal to 7 days, 8-14 days, 15-30 days, 31-60 days, and more than 60 days. Further, PVR type was classified as type 0 (No PVR), type 1 (PVR grade A and grade B), and type 2 (PVR grade C). The results were reported as mean and standard deviation for quantitative variables and percentage for categorical variables. Univariate and multivariable ordered logistic regression models were used to estimate the crude and adjusted odds ratios (ORs) and their 95% confidence interval (CIs) for SO-C according to TDH, and PVR severity according to SO-C. The Brant test of parallel regression assumption was used to test whether the relationship between each pair of outcome groups was the same. A nonsignificant test statistic provided evidence that the parallel regression assumption had not been violated. We used univariate and multiple linear regression anal-ysis to estimate the crude and adjusted coefficients and their 95% CIs to assess the association between initial BCVA and TDH. Furthermore, the univar-iate and multivariable logistic regression model was used to estimate the crude and adjusted ORs and their 95% CIs for 6mo-FA according to TDH. In all multivariable adjustments, age and sex were included. IBM SPSS version 23 and Stata version 15 (StataCorp, College Station, TX, USA) were used to perform all the statistical analyses. P values <0.05 were considered statistically significant. Retinal Detachment (RD) found in 387 patients consisted of 229 (59.2%) males and 158 (40.8%) females, with the age range of 7-76 years (mean± SD: 46.3±13.9 years) (Table 1). The majority of the patients (359; 92.8%) came from Java Island. Of the 387 patients, 172 (44.4%) came from a distance of less than or equal to 30 km from DSGAH, and 94 (24.3%) were from a distance of more than 120 km (Table 1). The mean ± SD travel distance to the referral hospital (TDH) was 160.9±364 km with a 38median of 52 (10-2819) km. The mean ± SD period from symptom onset to consultation (SO-C) was 183.5±456 days with a median of 30 (2-3775) days. When broken down into categories, most patients came with a SO-C of more than 60 days (128; 33.1%) (Table 1). After the adjustment for age and sex, compared to the TDH of less than or equal to 30 km, only the TDH of more than 120 km distance was significantly associated with a longer SO-C (adjusted OR 1.78; 95% CI 1.09-2.92) (Table 2). The result of the brant test for proportional odds assumption was not statistically significant (p = 0.31), indicating that this method of analysis was appropriate for this study.Proliferative vitreoretinopathy (PVR) prior to surgery was noted in 17.6% (13.9-21.7) patients consisting of PVR grade A-B (39; 10.1%) and C (29; 7.5%), while most of the cases (225; 58.1%) were without PVR. After the adjustment for age and sex, compared to the SO-C of less than or equal to 7 days, only the SO-C of 31-60 days was significantly associated with advanced PVR type (adjusted OR 4.28; 95% CI 1.47-12.51) (Table 3). The result of the brant test for proportional odds assumption was not statistically significant (p = 0.34), indicating that this method of analysis was appropriate for this study. Macula off presented in 274 (70.8%: 95% CI 66.0-75.3) patients. Table 4 shows the visual acuity at the time of the initial examination and after the 6-month follow-up. The initial BCVA of less than 3/60 (LogMAR 1.3) was most encountered (81.1%). The mean initial BCVA was LogMAR 1.96±0.58 (range: LogMAR 0.0-3.0). The mean BCVA 6 months after surgery was LogMAR 1.42±0.59 (range: LogMAR 0.1-2.7). Table 5 presents the results of linear regressions to evaluate the association between initial BCVA and TDH. After the adjustment for age and sex, no significant association was evident between initial BCVA and TDH.Of the 387 patients, 72 (18.6 %: 95% CI 14.9-22.8) could be followed up for 6 months. Table 6 shows the results of logistic regressions to evaluate the association between TDH and 6 months follow-up attendance (6mo-FA). Again, only the TDH of more than 120 km was significantly associated with 6mo-FA (adjusted OR 0.46; CI 95% 0.27-0.93).Results
