To identify factors predictive of outcome following retinectomy for complicated retinal detachment.
Retrospective, consecutive, single-centre series from January 2002 until December 2004 at Moorfields Eye Hospital. Functional outcome was defined by WHO classification of visual impairment; No visual impairment (≥20/60), Low vision (<20/60-20/400), Blindness (<20/400). Factors predictive of outcome were evaluated by univariate analysis.
One hundred and forty-five eyes underwent retinectomy; 92 male and 53 female; mean age of 55.4 years; 67 right eyes and 78 left eyes. The indications for retinectomy were rhegmatogenous retinal detachment (122 eyes), blunt trauma (27), tractional retinal detachment (15) and uveitic retinal detachment (8). Overall visual outcome was no visual impairment in 16%, low vision in 33% and blindness in 51%. Retinal redetachment occurred in 33%. Complications occurred in 30 eyes during the peri-operative period and in 109 in the long-term, including 11 cases of hypotony and 1 case of sympathetic ophthalmitis. Factors predictive of favourable visual outcome were early PVR, early surgery (within 100 days) and 360º barrier laser (>30% reduced risk of re-detachment). Uveitic and traumatic detachment were significantly associated with blindness.
In this large series we have identified several pre-operative factors that are predictive of visual outcome following retinectomy.
