Post Filtering Surgery Globe Massage-induced Keratoconus in an Eye with Iridocorneal Endothelial Syndrome: A Case Report and Literature Brief Review

PURPOSE: To report a case of unilateral post trabeculectomy globe massage-induced keratoconus (KCN). CASE REPORT: A 52-year-old lady with a history of trabeculectomy due to iridocorneal endothelial syndrome in her right eye was instructed to massage her globe to control gradual rise of intraocular pressure 1.5 years after surgery. The patient experienced high astigmatism and marked inferior corneal steepening after 3 years of globe massage. The left eye was normal in all aspects. Findings in different visual examinations were compatible with the diagnosis of unilateral KCN in the right eye of our patient. CONCLUSION: Chronic forceful frequent eye rubbing particularly with fingertips can be assumed to be the most important causative factor for KCN formation in this patient.
