45 year old male presented with defective vision BE since childhood , more marked for the past 1 year(RE>LE). On examination BCVA- RE-2/60 LE-5/60, anterior segment showed BE -iris coloboma (infero- nasal), immature cataract (RE>LE). Posterior segment showed RE-hazy view, LE-RC coloboma(TYPE 3 IDA MANN CLASSIFICATION) with shallow detached retina infero-temporally (below inferior arcade ) with suspicious break at 6 o clock position. Barrage laser was planned, on table subretinal fluid was found to extend posteriorly upto macula. Case was reviewed. LE- OCT&FFA showed features of CSCR.Treated with focal laser and prophylactic barrage around the coloboma. Incidence of RC coloboma is 0.14% , in which 40% will have retinal detachment(RD) due to break .Finding break in rudimentary retina is extremely difficult. Even though rhegmatogenous RD common in RC coloboma other causes (including CSCR) can also lead to RD.So far few cases have been reported CSCR mimic as RD in RC coloboma.
