Purpose: To describe the clinical features, prognostic factors, safety and rate of success of surgery and visual outcomes in patients with rhegmatogenous retinal detachment (RRD) and choroidal melanoma (CM).
Methods: A retrospective, observational case-series of 21 patients with rhegmatogenous retinal detachment or combined tractional-rhegmatogenous retinal detachment in patients with choroidal melanoma over a period of 20 years.
Results: Nineteen patients were included in the final analysis. The mean elevation of CM was 4.0 mm and the mean largest diameter was 11.0 mm. RRD occurred after the CM treatment in 14 eyes at a mean interval of 44.2 months. The RRD was macula-on RRD in 6 eyes, there was posterior vitreous detachment (PVD) in 15 and PVR in 7 eyes. BCVA at presentation was 0.71 logMAR and final was 1.5 logMAR (p = 0.01). The primary surgical success rate was 59%. No intraocular or extraocular tumour dissemination occurred. Mean follow-up was 66 months.
Conclusion: RRD in patients with CM is uncommon but requires multidisciplinary management. Anatomical results are favourable but visual outcomes are poor due to a combination of factors related to melanoma treatment, macular retinal detachment and PVR. Vitrectomy as a surgical intervention for RRD in treated CM appears to be safe in terms tumour dissemination.
