Outcomes of Glaucoma Drainage Device Surgery in Eyes with Treated Uveal Melanoma

Aim: We report patient safety and intraocular pressure (IOP) control after placement of a glaucoma drainage device (GDD) in eyes with a history of treated malignant uveal melanoma. Methods: A retrospective review of the records of patients with uveal melanoma was performed. Outcomes were local tumor recurrence, rate of metastases, and tonometric success, based on survival curves, defined as IOP < 21 mm Hg. Results: Eleven eyes with choroidal melanoma, 4 with iris melanoma, and 1 with ciliary body melanoma were followed for a median (interquartile range) of 2.1 (1.1-3.2) years. Two subjects developed liver metastases; one had monosomy 3 and tumor gene expression profile class 2. The other case with ciliary body melanoma was negative for monosomy 3. There were no cases of local treatment failure. Mean preoperative IOP decreased from 30.5 +/- 7.7 to 15.9 +/- 8.1 mm Hg at 1 year after surgery (1-year success rate 80%). Conclusions: Our case series with a median follow-up of 2 years shows that placing a GDD in patients with treated uveal melanoma does not expose patients to greater risk of local or extraocular recurrence. A larger series and longer follow-up time are required to fully evaluate the safety of GDDs in this clinical scenario. (C) 2018 S. Karger AG, Basel
