ABSTRACT
Snowflake degeneration is a late complication of polymethyl methacrylate (PMMA) intraocular lens implants. We report a case of asymptomatic advanced snowflake opacification presenting 13 years after implantation who maintained a visual acuity of 6/6. This report serves to illustrate the variability of the clinical effects of snowflake degeneration, which do not necessarily correlate with slit-lamp appearances.

The association of uveitis and vitiligo has long been established in specific disease entities: Vogt-Koyanagi-Harada syndrome and sympathetic ophthalmia. We report an unusual case of topical chloramphenicol allergy associated with an anterior uveitis with subsequent poliosis and periocular vitiligo, following anterior approach levator advancement surgery.

A 59-year-old woman underwent enucleation for choroidal melanoma. She had a late recurrence of the melanoma, which was treated with surgery and radiotherapy. Nine years after radiation treatment, she presented with pain and an orbital mass. Biopsy of the mass revealed an osteoblastic osteosarcoma. This report describes the late recurrence of choroidal melanoma and subsequent radiation-induced osteosarcoma. The risk of radiation-induced malignancy should be considered in all patients receiving radiotherapy. Despite yearly review, osteosarcoma was diagnosed only when the patient had symptoms, thus raising questions about the merits of long-term follow-up in detecting recurrence or emergence of secondary tumors.
