PURPOSE: We present eight cases of patients with choroidal melanoma referred to Hospital Serdang, a tertiary centre for oculoplastic issues, from 2021 to 2022.
METHOD: A retrospective case series of patients diagnosed with choroidal melanoma and referred to the Oculoplastic Clinic, Department of Ophthalmology, Hospital Serdang, was undertaken.
RESULTS: A total of eight cases of choroidal melanoma were identified, with a median age of 65 years. Six of them were female, and two were male. There were five of Malay ethnicity, and three were Chinese. Progressive reduced vision (n = 6), noticeable ocular mass (n = 3), and visual field defect (n = 2) were the most common presenting symptoms. The mean tumour thickness was 21.25 mm (range = 10-56 mm), and the largest basal diameter ranged from 10 mm to 53 mm (mean = 22.5 mm). Most were large tumours (n = 7) and above the T3a stage. The level of lactate dehydrogenase (LDH) was elevated in three cases. Histopathologically, five of the tumours were epithelioid, while the other three were mixed types. All patients underwent enucleation (n = 5) and exenteration (n = 3) with one recurrence. One patient had liver metastasis on the diagnosis of choroidal melanoma.
CONCLUSION: In Malaysia, there is an increasing number of cases of choroidal melanoma. Clinical evaluation remained the mainstay of diagnosis. Treatment should be based on multifactorial prognostication in addition to tumour size. The LDH level may be necessary for providing inexpensive but valuable prognostication and monitoring markers.
