To evaluate the effect of silicone oil (SO) on best-corrected visual acuity in phakic and pseudophakic vitrectomizied eyes.
Material and methods:
This prospective comparative case-control study evaluated the best-corrected visual acuity (BCVA) in SO filled vitrectomizied eyes (case group 64 eyes) compared to the vitrectomizied eyes without SO injection (control group 46 eyes). The preoperative and postoperative BCVA evaluated by Snellen chart were compared between two groups. Exclusion criteria was consist of aphakia, any degree of anterior chamber inflammation, SO bubbles in anterior chamber and increased intraocular pressure in postoperative period.
In the silicone oil group mean SD preoperative log MAR of BCVA was 1.76 0.60 compared to 1.82 0.52 in control group (P= 0.655), and mean postoperative log MAR of BCVA was 1.68 0.56 compared to 1.55 0.63 in control group (P = 0.23). There were no significant differences among groups.
