Abstract
PURPOSE: To determine the prevalence, clinical characteristics, and demographic factors of melanocytic lesions of the ocular surface, such as racial melanosis, primarily acquired melanosis, conjunctival nevus, and conjunctival melanoma in a Hispanic population. MATERIALS AND METHODS: A cross-sectional and observational study was undertaken in a tertiary referral ophthalmological center in northern Mexico from December 2020 to April 2021. All patients attending an ophthalmology specialty clinic were screened during their first visit in order to detect melanocytic lesions of the ocular surface. Demographic factors, clinical characteristics, and diagnosis and treatment were recorded. RESULTS: 227 patients were screened for melanocytic lesions. Melanocytic lesions were identified in 114 patients (50.2%). The prevalence of the different melanocytic lesions in the screened population was racial melanosis, 45.3%; primary acquired melanosis, 3.5%, and conjunctival nevus 1.3%. No conjunctival melanoma was identified in the screened population. Primary acquired melanosis was more common in the fifth to sixth decade of life and in females. Racial melanosis showed no gender predilection and was also more common in the fifth to sixth decade of life. Only 1 melanocytic lesion (a primary acquired melanosis) required medical treatment with excisional biopsy and cryotherapy. CONCLUSION: The prevalence of racial melanosis is remarkably high in the Hispanic population. While less prevalent, primary acquired melanosis is also present in a considerable percentage of Hispanic patients. Both melanocytic lesions exhibit demographic characteristics that match those previously reported in the medical literature.
