COLORADO SPRINGS, Colo. — Combined pars plana vitrectomy and penetrating keratoplasty stabilized visual acuity but yielded only modest visual gains, according to a scientific poster presented at the American Ophthalmological Society meeting here.
Randee Watson, MD, and colleagues reported results of a retrospective, single-center, multi-surgeon study of 79 eyes that underwent combined PPV and PK between 2001 and 2013; 65 eyes underwent a single combined procedure, 11 eyes underwent two combined procedures, and three eyes underwent a third procedure.
PPV was most commonly indicated for retinal detachment (65%), and PK was most commonly indicated for corneal decompensation (43%).
Mean logMAR visual acuity was 2.67 preoperatively, 2.23 at 1 month, 2.21 at 6 months, 2.43 at 1 year and 2.48 at final follow-up.
Snellen visual acuity was 20/400 or worse in 15% of eyes; 15% of eyes gained two or more lines of vision after surgery.
Corneal graft failure occurred in 40 eyes (51%), recurrent retinal detachment in 22 eyes (28%) and hypotony in 20 eyes (25%).
Silicone oil endotamponade and postoperative retinal detachment were associated (P = .045), while previous ocular trauma and postoperative corneal graft failure were associated (P = .023).
“The results of survival analysis performed in this study indicate that while a majority of eyes achieved durable retinal attachment following PPV-PK, there was a significant incidence of postoperative ocular morbidity,” the study authors wrote. – by Matt Hasson and Patricia Nale, ELS
