PARS-PLANA VITRECTOMY FOR RETINAL-DETACHMENT DUE TO INTERNAL POSTERIOR OPHTHALMOMYIASIS AFTER CATARACT-EXTRACTION

Background: The authors report a case of posterior internal ophthalmom yiasis causing vitreous haemorrhage and retinal detachment after uncom plicated cataract extration. Case report: The patient suffered an abru pt vitreous haemorrhage 9 days after ECCE and posterior chamber IOL im plantation. After 2 months the haemorrhage did not clear up and a reti nal detachment arose. The patient underwent encircling scleral buckle, pars plana vitrectomy and fluid-gas exchange. In course of interventi on the surgeon removed from the vitreous chamber a 14-mm-long round wo rm subsequently identified as a dipterous larva of the Sarcophagidae f amily. Discussion: The patient showed no sign of subretinal tracking o r retinal breaks or holes. The sclerocorneal surgical wound seems the most likely site of entrance of the parasite, and this would then be t he first reported case of myiasis with no RPE tracking.
