Comparison of Silicone Oil Retention Sutures <em>versus</em> Inferior Peripheral Iridectomy for Preventing Silicone Oil Migration into the Anterior Chamber in Vitrectomised Unicameral Aphakic Eyes.

内容摘要

To evaluate the effectiveness of silicone oil retention sutures versus inferior peripheral iridectomy (PI) in avoiding silicone oil migration in vitrectomised unicameral aphakic eyes. A quasi-experimental study. Place and Duration of the Study: College of Ophthalmology and Allied Vision Sciences, King Edward Medical University/Mayo Hospital, Lahore, Pakistan, from March 2023 to August 2023. Patients aged over 20 years, of either gender, who underwent pars plana vitrectomy resulting in single-segment vitrectomised aphakic eyes, were randomly segregated into two study groups. In Group A, patients underwent pars plana vitrectomy with the placement of 10-0 Prolene sutures applied through the anterior chamber of the eye (retention sutures), followed by silicone oil endotamponade. In Group B, patients underwent pars plana vitrectomy with inferior PI, followed by silicone oil endotamponade. All the patients were followed up for four weeks, after which a comparative analysis was performed using SPSS version 28. The chi-square test was applied to compare the two surgical techniques. A total of 102 patients were enrolled in this study. Patients enrolled in Group A had a mean age of 49.55 &#xb1; 7.44 years. Those enrolled in Group B had a mean age of 45.96 &#xb1; 8.36 years. In Group A, there were 39 (76.5%) males and 12 (23.5%) females. In Group B, there were 33 (64.7%) males and 18 (35.3%) females. In Group A, prolapse of polydimethylsiloxane (PDMS)/silicone oil into the ocular anterior chamber was observed in six (11.8%) eyes. In Group B, migration of PDMS/silicone oil into the anterior chamber was observed in 16 (31.4%) eyes. A statistically significant difference in PDMS/silicone oil prolapse into the anterior chamber of the eyes was observed between the two study groups (p <0.05), proving that the retention suture group was superior to the PI group. The silicone oil retention suturing technique is associated with a lower frequency of PDMS/ silicone oil migration into the anterior chamber compared to the current gold standard, inferior PI, after pars plana vitrectomy in unicameral aphakic eyes.
