Journal of the College of Physicians and Surgeons

Layton Rahmatullah Benevolent Trust (LRBT), Lahore, from June 2010 to October 2011. A total of 107 eyes underwent RRD surgery. Detailed diagrams were drawn pre-operatively for all. Other recorded details included, bio-data, age, gender, visual acuity, autorefractometery, predisposing risk factors, lens state and duration of symptoms. The data was
... s. The data was analyzed with respect to age and gender distribution, frequency of various risk factors for RRD, duration of RRD and its various presenting characteristics. Mean age of the patients were 33.1 ± 1.5 years, 85% were males. Bilateral RRD was discovered in 2.8% patients. No identifiable risk factor for RRD was present in 28%, while in rest of the 72% eyes, the commonest risk factors were intraocular surgery, trauma and peripheral myopic degeneration in decreasing order of frequency. There were 70.1% phakic, 23.4% pseudophakic and 6.5% aphakic eyes. Majority (93.5%) presented with macula off detachment. There was an overall average time lapse of 97.24 ± 16.95 days between presenting and first occurrence of symptoms. In 31.8% of eyes no break could be found pre-operatively, while 38.3% had 1 and 29.9% eyes had ³ 2 breaks. Majority of the primary breaks were horse-shoe tears (42.1%). Total RRD was found in 35.5% eyes. Infero-temporal and supero-temporal were the most frequently involved quadrants (93.5% and 86.9% respectively). Intraocular surgery, trauma and lattice degeneration in myopia are established common risk factors for RRD.
