PURPOSE: To describe the occurrence of orbital fat prolapse and blepharoptosis after posterior sub-Tenon (PST) triamcinolone injection. DESIGN: Retrospective review of consecutive case series. PARTICIPANTS: Patients with ptosis and orbital fat herniation after PST triamcinolone injection. METHODS: Charts of all patients with ptosis and orbital fat herniation presenting after PST triamcinolone injection to the oculoplastics service of the Cole Eye Institute between 1999 and 2003 were reviewed. Charts were reviewed for patient age, indication, dates of injections, time to patient complaint or time to referral for ptosis, and marginal reflex distance (MRD1). MAIN OUTCOME MEASURES: Ptosis and orbital fat herniation after PST triamcinolone injection. RESULTS: Eleven patients with a history of ipsilateral PST triamcinolone injections were seen with ptosis and orbital fat prolapse. Ten charts were available for review. Mean patient age was 64 years (range, 45-78 years). Patients underwent 1 to 9 ipsilateral injections, and 2 patients underwent bilateral injections. Patients were seen for ptosis evaluation on average 22.5 months (range, 3-56 months) after the initial injection, and 6.6 months (range, 0-20 months) after the most recent injection. All patients demonstrated significant orbital fat prolapse in conjunction with statistically significant ptosis (P = 0.016). Tissue was obtained in 3 cases. Histologic findings in 1 case showed orbital fat infiltrated by histiocytes that seemed to contain phagocytosed material. CONCLUSIONS: Posterior sub-Tenon triamcinolone injection may cause ptosis associated with orbital fat prolapse. This finding may be a relatively common complication of PST triamcinolone injection. We recommend counseling patients about this risk before PST triamcinolone injection.
