Sixty-one patients with siliconized eyes underwent removal of SO with two different techniques and were divided into fluid-air exchange and oil-fluid exchange groups. To quantify the residual silicone droplets objectively, B-scan echographic images were analyzed within seven days of surgery. Silicone oil index (SOI) which is the amount of residual SO droplets/vitreal area in the images was calculated with the help of imagej software.</p> <p><em><strong>Results:</strong></em> The residual SOI of the fluid-air exchange group (0.99 ± 1.76%) was significantly lower than the oil-fluid exchange group (3.25 ± 3.85%). The SOI is positively correlated with the duration of tamponade, preoperative intraocular- pressure and axial length. Persistent IOP elevation post-operatively was seen in 16.67% individuals in the fluid-air exchange group and 54.8% individuals in the oil-fluid exchange group.</p> <p><em><strong>Conclusion:</strong></em> Fluid-air exchange group was found to be superior in reducing residual SO droplets than the oil-fluid exchange group.</p> <p><strong>doi: https://doi.org/10.12669/pjms.39.2.6243</strong></p> <p><em><strong>How to cite this:</strong></em> Rizwan A, Javaid RMM, Latif S, Sarwar MS, Khan AA.
