Squint Free Papers Table 1: Motor Outcome: Correlation of BPS groups with motor outcome BPS grade motor outcome (% of patients) Good Fair Poor I- very good (n=3) 67 33 0 II- good (n=8) 84 16 0 III- fair (n=12) 64 9 27 IV- poor (n=5) 60 0 40 A significant improvement in the BF score was seen post-op (p=0.0002). The ANOVA result showed a significant difference in the mean improvement (as a percentage of scope of improvement) between BPS groups (p=0.0036)[table 2]. A significant difference in percentage of improvement was seen between group II (good) and group IV (poor) (p=0.003) [table 3]. Table 2: Sensory Otcome: Comparison of pre-op BPS with Binocular function (BF) score Bps Mean Mean Mean Mean Grade Pre-op Bf Post-op Bf Improvemen Improvemen Score Score T T as A % of Scope for Improvemen T I-very good 9±1.7 10±0 1.0±1.7 100 II-good 3.7±1.9 10±0 6.3±1.9 100±0 III-fair 4.7±3.4 7.3±3.8 2.5±3.5 50±53.5 IV-poor 2.8±0.4 3.6±1.3 0.8±1.8 10±22.4 Table 3: Inter BPS group comparison for percentage improvement in BF score Between grades P value for difference in % improvement of BF score Good vs fair 0.071 Good vs poor 0.003 Fair vs poor 0.230 Those with pre-op BF score 10 (2 patients in group I and 3 in group III) were excluded from this analysis because they had no scope for improvement. Since there was only one observation left in “Very good’ group after this, it was not possible to estimate the standard error and therefore this group was not considered for comparison of means. 833
