What repair for inferior mac on detachment with ifneronasal dialysis and no PVD
Scleraly buckle and cryo
What is PVR A
Proliferative vitreoretinoapthy - massive vitreous traction and preretinal proliferation
Vitreous haze
Pigment clumps
Pigment clusters on inferior retina
What is PVR B
Wrinkling of inner retinal surface
Vessel tortuosity
Rolled edge of retinal break
What is PVR CP (1-12)
Full thickness retinal folds or subretinal strands POSTERIOR to equator
Further divided into focal, diffuse and subretinal subtypes
Clock hours
What is PVR CA (1-12)
Full thickness retinal folds or subretinal strands ANTERIOR to the equator
Clock hours

Not giving IC cefuroxime
(clear conreal incision vs scleral tunnel)
Silicone IOL
