A 26-year-old female having a history of retinoblastoma with her two children was referred for evaluation. Examination revealed a visual acuity of 20/20 in each eye. The anterior segment was unremarkable in both eyes. Left eye fundus examination revealed a slightly elevated translucent grayish lesion with ill-defined margins in the inferonasal quadrant [Figure 1]a. Right eye examination was within normal limits.

(b) B-scan ultrasonography of the left eye showing a slightly elevated lesion away from the optic disc with a corresponding high-amplitude spike. (c) Swept-source optical coherence tomography showing an elevated featureless retinal mass over a thinned choroidal layer possessing only deeper large caliber vessels. (d) Fundus fluorescein angiography showing omega-shaped bend with a delayed filling of the retinal veins with window defect.

(f and g) Optical coherence tomography angiography of the choroid revealing complete loss of superficial choriocapillaris with deeper choroidal vessels

B-scan ultrasonography of the posterior segment revealed a slightly elevated lesion with corresponding high-amplitude reflectivity [Figure 1]b. Swept-source optical coherence tomography (OCT) showed an elevated retinal lesion with an undulating inner surface. The lesion had uniform moderate reflectivity, and none of the layers of the neurosensory retina could be appreciated. The underlying retinal pigment epithelium was visible only in a limited part of the mass and in the rest it appeared atrophic. Underlying choroid was markedly thinned out with only a single layer of vessels seen within it. The chorioscleral interface could be clearly made out [Figure 1]c. Fluorescein angiography highlighted an overlying omega-shaped tortuous vessel with surrounding faint diffuse hyperfluorescence. The underlying larger choroidal vessels were easily visible (window defect) [Figure 1]d. There was no leakage appreciable from or around the mass. Indocyanine green angiography further highlighted the choroidal vessels under and around the lesion [Figure 1]e. OCT-angiography (OCT-A) revealed the presence of intact superficial and deep retinal vascular plexus. The configuration or pattern of these vessels was a bit disorganized, likely due to the mass effect. The mild hyperfluorescence seen in the tumor substance is likely due to these vessels. On deeper segmentation of OCT-A, larger choroidal vessels could also be appreciated due to atrophy of overlying choriocapillaris [Figure 1]f and [Figure 1]g.

Retinocytoma is a benign variant of retinoblastoma.[1] Singh et al. observed the presence of a translucent retinal mass in 21 (88%), calcification in 15 (63%), and retinal pigment epithelial alteration in 13 (54%) of 24 such tumors.[2] Our case revealed a translucent mass with a underlying chorioretinal atrophy.


  Conclusion Top


Noninvasive multimodal imaging in the form of OCT and OCT-A may prove to be useful in following up of patients with retinocytoma
