Posterior vitreous detachment rate varies based on disease type

ORLANDO, Fla. — The posterior vitreous detachment rate of highly myopic eyes measured intraoperatively is low and variable depending on disease type, according to a study presented here at the Association for Research in Vision and Ophthalmology meeting.
“Vitrectomy with systematic use of vitreous visualization agents and attentive peeling of epiretinal structures could be recommended in highly myopic eyes,” co-author Ramin Tadayoni, MD, and colleagues said in a poster presentation.
Ninety-six highly myopic eyes of 95 patients underwent 25-gauge three-port pars plana vitrectomy in a span of 3 years.
Retinal detachment (RD) was diagnosed in 20 eyes, epiretinal membrane (ERM) in 31 eyes, macular hole retinal detachment (MHRD) in 14 eyes, myopic foveoschisis (FVS) in 21 eyes and macular hole (MH) in 10 eyes.
“PVD rate in highly myopic eyes is lower than what we expect looking through the literature, at least in eyes that need surgery. Macular hole is usually a PVD-related disease, but in purely myopic eyes, most of them don’t have PVD, so that means maybe the physiology is different in highly myopic eyes,” Tadayoni told Ocular Surgery News.
Overall, posterior vitreous detachment (PVD) rate was at 52.1% in highly myopic eyes that required vitrectomy, but the rate fluctuated among diseases. PVD was higher in RD and ERM with rates at 85% and 74.1%, respectively. PVD was lower in MHRD, FVS and MH with rates at 42.9%, 14.3% and 10%, respectively.
