PURPOSE:To identify risk factors for bilateral rhegmatogenous retinal detachments (RRD) and analyse the visual outcome in these patients.
Dr. Rajendra Prasad Centre for Ophthalmic Sciences, All India Institute of Medical Sciences, New Delhi, India.
This was a retrospective study of office records and retinal diagrams on 61 patients with bilateral RRD with at least 6 months of follow up. Data collected included age, gender, best corrected visual acuity (BCVA), refractive error, ocular and systemic risk factors, socioeconomic status, lenticular status, fundus pathologies, type of break and detachment, and final visual outcome.
The age ranged from 1 year to 80 years with a mean of 37.6 years. Male predominance was noted with about 80% male patients. 72% patients had poor socioeconomic status. 52 eyes were phakic, 46 pseudophakic and 24 were aphakic. Pseudophakia alone was the most important risk factor in 24.2% patients followed by myopia(14.8%). Aphakia alone was seen in 9.8% followed by aphakia along with myopia in 6.6%. 64% patients had mild to moderate myopia with only 9.8 % patients with pathological myopia. 9 pseudophakic eyes had posterior capsular defect. 4 eyes detached despite prophylactic laser or cryoretinopexy. Most patients presented with total detachment (51%) and horse shoe tear was the most frequently seen break (64%). 50% of the eyes eventually had visual acuity better than 636 however 15 eyes lost light perception including 6 eyes which were phthisical. 20 eyes had only light perception at final follow up. Time of presentation varied from 5 days to 1 year from onset of diminution of vision.
Cataract surgery is a significant risk factor for bilateral RRD. A number of eyes are lost due to inoperable retinal detachment due to delay in presentation, and 33% eyes had final visual acuity worse than hand movements. Poor socioeconomic status is an important barrier to early management in cases of bilateral RRD.
