Ultra-wide-field imaging assessment of small choroidal pigmented lesions using red and green colour channels.

ABSTRACT:

Background

Diagnosis of small choroidal melanoma is mainly based on tumour thickness, subretinal fluid, or lipofuscin pigment. Ultra-wide-field imaging (UWF) allows depiction of choroidal lesions through a red (RC) and a green channel (GC). Aim of the study was to determine the utility of this tool in the detection of small choroidal melanoma.

Methods

Retrospective cross-sectional study of patients with small choroidal pigmented lesions up to 3 mm in thickness. All patients underwent clinical and imaging assessment including UWF. Lesions were subcategorized based on thickness and lesion type. A qualitative assessment ensued using the red and green channels feature.

Results

A total of 152 patients were included. Melanotic naevi (76/152,50%) and small choroidal melanoma
