Abstract :
Purpose: To describe the multicolor imaging (MCI) features in a series of patients diagnosed with a choroidal nevus and compare it vis‑à‑vis
color fundus photography (CFP) in identifying the lesion.
Methods: In this retrospective, descriptive case series at a tertiary referral center in South India, all patients diagnosed with the choroidal
nevus underwent CFP, optical coherence tomography, MCI, and infrared reflectance (IR) imaging.
Results: In this study, we found that on MCI, the choroidal nevus could be identified in only six of the 12 eyes. The lesions were seen as
an area of hyperreflectance on IR image and orange‑colored lesion on multicolor image. In one eye, there was a mixed pattern of hyper and
hyporeflectance on IR imaging. The remaining five eyes with choroidal nevus lesions were not identified on MCI.
Conclusion: The variable features of the choroidal nevus on MCI are most likely due to the variable melanin content within the nevus cells.
Further studies are needed to validate these findings.
