“…They show hyperreflectance on the infrared channel and appear 'salmon pink' on the multicolour image. 3 This is in contrast to the current case where the lesion appeared dark (hyporeflective) on the infrared reflectance channel. This can be explained based on the light absorption properties of melanin.…”

“…Previous studies used swept-source OCT, 5 near infra-red reflectance 6 and multicolour imaging to characterise pigmented and non-pigmented choroidal nevi and to distinguish them from malignant tumours. 3 Absence of pigmentation in amelanotic lesions helps to study the internal architecture and vascular component using MI. A small lesion size, plateau configuration and absence of secondary retinal changes warrant no further intervention except for regular follow-up as in the present case.…”

“…In this table, we summarized the observations of MCI and its advantages found in published papers. The list is not exhaustive; however, it highlights the salient features of different retinal and choroidal disorders [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38].…”

Background: Dengue fever is associated with various sight-threatening ocular manifestations, some of which can occur several months after fever. These include subconjunctival hemorrhage, vitreous hemorrhage, retinal hemorrhage, cotton wool spots, central and branch retinal artery occlusion, central scotoma, papilledema, optic neuropathy, retinal vasculitis, retinitis, retinal pigment epithelium mottling, foveolitis, choroidal effusion, exudative retinal detachment, anterior uveitis, endogenous endophthalmitis, and panophthalmitis. Herein, we report a patient with unilateral central retinal artery occlusion (CRAO) and raised dengue immunoglobulin G (IgG) titers who underwent serial multimodal imaging with fundus photography, spectral domain optical coherence tomography (SD-OCT), optical coherence tomography angiography (OCTA), and multi-color imaging (MCI). Furthermore, we reviewed recent publications highlighting different eye diseases and the role of MCI in their diagnosis and serial monitoring. Case presentation: A 53-year-old Asian Indian woman complained of blurring of vision in the right eye (OD) two months after a bout of fever. Her best-corrected distance visual acuity was finger counting close to the face in the OD and 20/40 in the left eye. CRAO of the OD was diagnosed. Systemic investigations were normal except for elevated dengue IgG levels. Optical coherence tomography and fluorescein angiography confirmed this diagnosis. MCI and SD-OCT using Spectralis™ performed before and after treatment with oral steroids demonstrated improvement. MCI served as a noninvasive ancillary tool for monitoring the CRAO. In addition to the case report, we summarize articles pertaining to MCI published during the years 2018–2022. The list is not exhaustive but highlights salient features of different retinal and choroidal disorders evaluated using MCI. Our summary highlights the role of MCI in the diagnosis and serial monitoring of eye diseases. Conclusions: A diagnosis of post-dengue fever retinal artery occlusion should be made after ruling out other causes of retinal artery vascular occlusion. We demonstrated retinal changes using serial imaging. MCI can be a useful tool, along with SD-OCT, to monitor clinical improvement. Optometrists can follow up patients with retinal vascular occlusions using noninvasive methods.

“…From the description of the MultiColor ® imaging features in the current series of cases, it is likely that the lesion consists of an accumulation of choroidal melanocytes. As a result, pathologies characterized by increased pigmentation on the choroid such as choroidal nevus, choroidal melanoma, and isolated choroidal melanocytosis must be considered [ 16 , 17 , 18 , 19 ].…”

“…Choroidal nevus is a brown or tan mass with a round or oval shape that is located deep beneath the retinal pigment epithelium. Choroidal nevi are distinguished by variable thickness, distinctive OCT patterns, and distortions on fluorescein angiography [ 16 , 20 , 21 ]. In our series, this flat lesion was scarcely seen on clinical examination or documented on a conventional color fundus photograph as a pigmented lesion.…”

We report on a case series that revealed flat, choroidal lesions on optical coherence tomography (OCT) and on enface MultiColor® (MCI) imaging of the fundus but were not noticeable on clinical examination or conventional color fundus images. This observational study included 12 eyes from 11 patients who had distinct, orange-colored lesions on MCI. Retinal imaging was conducted using conventional color fundus photography and OCT. On the color fundus images and the blue and green reflectance channels of MCI, each of the lesions was difficult to distinguish. On the infrared channel, the lesion was identified as bright white in color and bright orange on the multicolor image. The lesion was identified on OCT as a flat, homogeneous hyperreflective lesion involving the choroid, with an intact overlying retinal pigment epithelium and retinal layers. A comparison of the clinical and imaging features with other known entities led to the conclusion that the lesion was a distinct clinical entity. The presence of melanin in the lesion was confirmed based on the retinal imaging findings and the light absorption properties of melanin. As a result, the lesion was named as ‘choroidal melanocytic hamartoma’. A longer follow-up is required to confirm the benign nature of this clinical entity.
