Anatomical and functional outcome following primary retinal re-attachment surgery in phakic and pseudophakic rhegmatogenesis retinal detachment.

Rhegmatogenous retinal detachment (rrd) is relatively unusual in general population: annual incidence is 1:10,000. objective of this study was to compare the anatomical and functional outcome of primary retinal re-attachment surgery in phakic and pseudophakic eyes. a case series comparative study was carried out at al-ibrahim eye hospital,karachi from july 2008 to june 2009. a total of 71 eyes of 69 patients either phakic (group-i) or pseudophakic (group-ii) rhegmatogenous retinal detachment (rrd) with proliferative vitreoretinopathy (pvr) up to grade c-3 were included in the study. eyes with rrd with pvr c-4 and above,corneal opacity and previous posterior segment surgery were excluded. pars plana vitrectomy (ppv) or scleral buckling procedure (sbp) was performed as a primary re-attachment surgery. patients were followed for at least 6 months. anatomical (retinal reattachment) and functional outcome (best corrected visual acuity) was noted at each follow up. anatomical outcome (retinal reattachment) was similar in group-i (93.02%) and group-ii (92.86%) eyes (p = 0.88). best corrected visual acuity (functional outcome) of 6/69 (see symbol) 6/18 was achieved in 46.5% in group-i and 10.7% in group-ii. raised intraocular pressure (lop) was observed as most common complication. primary retinal re-attachment surgery either in phakic (group-i) or pseudophakic (group-ii) eyes have similar anatomical outcome but functional outcome depends upon the status of macula at the time of surgery and level of proliferative vitreoretinopathy (pvr).
