Abstract
Purpose :
Since more extensive peripheral and anterior vitreous base shaving is possible in eyes with proliferative vitreoretinopathy that are pseudophakic or aphakic, it is believed that better anatomic outcomes may be achieved in such cases compared to eyes that are phakic. This study investigated the influence of phakia versus pseudophakia on the outcomes of retinectomy for RRD with PVR.
Methods :
This was a retrospective matched case-control study of consecutive eyes that underwent PPV with retinectomy for RRD with PVR between January 2015 and January 2020 with a minimum follow-up of six months. Phakic eyes were matched to pseudophakic control eyes in a 1:1 ratio for age, gender, and macular status. The main outcome measures were anatomic and visual outcomes at 6 months and at the final follow-up visit.
Results :
The study included 138 eyes (69 eyes in each group). The mean (SD) follow-up duration was 28.7 (9.2) months. Baseline characteristics including age, gender, smoking status, macular status, preoperative VA, and the extent of RRD, PVR, and retinectomy did not differ significantly between the groups. There were no significant differences in the rate of retinal reattachment without silicone oil (SO) [45% vs. 32% at 6 months, p=0.161 and 71% vs. 61% at the final follow-up, p=0.281], in the phakic and pseudophakic groups, respectively. There were also no significant differences in the rate of retinal reattachment regardless of the status of the SO (94% vs. 96% at 6 months [P=1.000] and 99% vs. 97% at the final follow-up [P=1.000], in the phakic and pseudophakic group, respectively). No significant difference in the mean (SD) logarithm of the minimum angle of resolution (logMAR) visual acuity was noted [1.46 (0.56) vs. 1.35 (0.69) at 6 months, p=0.249 and 0.99 (0.62) vs. 1.27 (0.81) at the final follow-up, p=0.064], in the phakic and pseudophakic groups, respectively. The incidence of postoperative ocular hypotony was also similar (1% vs. 4%, p=0.612).
Conclusions :
Both phakic and pseudophakic eyes that underwent retinectomy may achieve acceptable anatomic and visual outcomes regardless of the lens status. Phakic status does not appear to negatively impact the outcomes of retinectomy for RRD with PVR.
