Time between redetachment and retinectomy in eyes with proliferative vitreoretinopathy impacts outcomes

Several modifiable factors are associated with good visual acuity (VA) following repair of rhegmatogenous retinal detachments (RD) with proliferative vitreoretinopathy (PVR) undergoing retinectomy, according to a study.

In this interventional, retrospective, case-control study, 345 eyes that underwent retinectomy during repair of RD with PVR, were included. A good VA cohort of 62 eyes with a final VA ≥20/70 (good VA cohort) and a poor VA cohort of age- and gender-matched eyes with VA <20/70 were identified.

There was a mean final logMAR VA of 0.32 [Snellen 20/42] and 1.54 [Snellen 20/693] in the good VA cohort and poor VA cohort, respectively.
The following were significant predictors of good vision:

-Smaller initial RD size
-Fewer surgeries
-Shorter time between recurrent RD diagnosis and subsequent surgeries
-Better pre-operative VA
-Pseudophakia at final visit
