Hispanic patients with choroidal melanoma present younger and with more severe symptoms like eye pain and higher intraocular pressure. Their tumors are larger and more pigmented compared to white patients.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Background:

  • Choroidal melanomas are the most common primary intraocular malignancy.
  • Understanding demographic and clinical variations is crucial for early diagnosis and treatment.

Purpose of the Study:

  • To compare the clinical presentation and pathological features of choroidal melanomas in Hispanic versus white patients.
  • To identify potential ethnic disparities in choroidal melanoma characteristics.

Main Methods:

  • Retrospective review of 20 enucleated eyes from Hispanic patients diagnosed with choroidal melanoma between 1974-1992.
  • Comparison with 125 choroidal melanomas from randomly selected white patients during the same period.

Main Results:

  • Hispanic patients were younger at diagnosis and enucleation (P = .002).
  • More frequent eye pain (P = .016), red eye (P = .0002), and tearing (P = .012) in Hispanic patients.
  • Higher intraocular pressure (P = .001) and more rubeosis iridis (P < .0001) observed in Hispanic patients.
  • Tumors in Hispanic patients were larger (P = .003) and heavily pigmented (P = .0001).
  • Trends suggested less inflammation and more epithelioid cell type in Hispanic patients' tumors.

    • Conclusions:

    • Significant clinical and pathological differences exist in choroidal melanoma presentation between Hispanic and white patients.
    • Hispanic patients exhibit a more aggressive clinical profile, including younger age, increased symptoms, higher intraocular pressure, and larger, more pigmented tumors.
    • These findings highlight potential ethnic disparities in choroidal melanoma, warranting further investigation and tailored clinical approaches.
