Current management of choroidal malignant melanoma

|November 1, 1985

Summary

Malignant melanoma is the most common primary eye tumor, arising in the uveal tract, often the choroid. Its exact cause remains unknown, though it

Area of Science:

Background:

Malignant melanoma is the most frequent primary neoplasm originating within the eye.
This intraocular tumor typically develops in the uveal tract, with the choroid being the most commonly affected site, followed by the iris and ciliary body.
Ocular melanoma predominantly affects individuals in middle age, and its precise etiology is currently unknown.

Purpose of the Study:

To review the characteristics and known information regarding malignant melanoma of the uveal tract.
To discuss the potential origins and risk factors associated with intraocular melanoma.
To highlight the rarity of ocular melanoma in individuals of Black African descent despite heavy pigmentation of uveal tissue.

Main Methods:

Review of existing clinical and pathological data on intraocular melanoma.
Analysis of epidemiological patterns and etiological factors.
Examination of the relationship between pre-existing pigmented lesions and melanoma development.

Main Results:

Uveal melanoma is the most common primary intraocular tumor.
The choroid is the most frequent site of origin within the uveal tract.
While malignant change may occur in choroidal nevi, melanoma can also arise in the absence of pre-existing pigmented lesions.

Conclusions:

Malignant melanoma is a significant intraocular neoplasm primarily affecting the uveal tract.
The etiology of uveal melanoma is not fully understood.
Further research is needed to elucidate the origins and risk factors, particularly concerning racial variations.
