摘要

Purpose: To calculate AIP and to find correlation between hole closure pattern with AIP in idiopathic full thickness macular hole (FTMH) cases. Methods: In this prospective, non-randomized, interventional single blind study, 105 eyes of symptomatic FTMH (6 month duration) were operated. Minimal diameter of macular hole (MDMH) was calculated on OCT, divided into Group I (400μ, n = 75) and Group II (400μ, n = 30). 23G vitrectomy with ILM peeling and gas injection were done in all and recorded. Final area of ILM peeled (AIP) was calculated using Adobe Photoshop CS2 (PSD format) in disc diameters (DD) from still frame. Follow up was done at 6 monthly interval up to a maximum of 5 years after surgery. Results: Macular holes were closed in 92.38% eyes. In Group I, mean pre-operative BCVA was 1.14 ± 0.39 log MAR and was improved to 0.79 ± 0.26 log MAR post-operatively at 6 months. In Group II, mean pre-operative BCVA was 0.95 ± 0.44 log MAR and was improved to 0.60 ± 0.24 log MAR after surgery. When AIP was more than 3DD, Type I and Type II closure were 72.77% and 27.27% in Group I (P value 0.01) and 84.21% and 15.79% in Group II (P value 0.01). Conclusion: AIP can be calculated using Adobe Photoshop CS2. Type I closure was significantly high with AIP 3DD in both groups. Intra-operatively using video overlay, surgeons can increase the diameter of AIP to get better closure pattern.
