- To demonstrate a granulomatous reaction to silicone buckel thirteen years after retinal detachment surgery. We report on a 71-year-old man who developed a 360 degrees of epibulbar granulation tissue due to silicone circle buckel. The granulation tissue was demonstrated by a computer tomography and histologically. A granulomatous reaction to silicone circle buckel can be found many years from the first operation. Biopsy is always necessary to establish a definitive diagnosis. Treatment of 360 degrees of epibulbar granulation tissue causing ocular dysfunction is by surgical excision.
