Scleral Dellen after Routine Uneventful Pterygium Surgery.

ABSTRACT

Occurrence of Scleral Dellen is rare but serious complication with stromalinflammation with tissue loss and scarring. Scleral dellen results from localdehydration & thinning of scleral tissues with exposure of underlying uvea leading toblueish colour. Occular surgical causes of occurrence of scleral dellen are strabismussurgery, pterygium excision (with or without use of adjunctive treatment like betaradiation, conjunctival autograft and Mitomycin C), cataract extraction.1,2 Patientscomplain of foreign body sensation & mild discomfort. Treatment consists ofreduction or elimination of contributing perilimbal elevation, & rapid rehydrationwith artificial tears, eye ointment and patching3. If treated properly dellen usuallyresolves completely without permanent sequelae. We report a case of severe scleraldellen that occurred 14 days after the uneventful surgical excision of primarypterygium without adjuvant therapy. We describe a patient with scleral dellen, whichoccurred after an uneventful pterygium excision without adjunctive therapy.
