A 32-years-old male presented with poor vision in oculus sinister (OS) for the last 6 months. Best-corrected visual acuity was 20/20 with –8 diopters sphere OD and 20/200 with –10 diopters sphere OS. Fundus examination [Figure 1]a and [Figure 1]c showed tessellated fundus with visible large choroidal vessels oculus utro (OU) and choroidal neovascular membrane (CNVM) scar OS. Swept-source optical coherence tomography (SS-OCT) showed type 2 CNVM without any subretinal or intraretinal fluid. Additionally, it revealed the presence of tractional retinoschisis nasal to optic disc OU similar to myopic traction maculopathy (MTM) [Figure 1]b and [Figure 1]d., While OS had posterior staphyloma nasal to the disc, no staphyloma was noted OD. In view of no features of active CNVM, no treatment was prescribed and the patient was advised a regular follow-up. This case highlights the occurrence of a common finding at a rare location and utility of SS-OCT in better phenotypic characterization of MTM. The presence of extramacular schisis may further add to the visual disability of these patients as central vision is frequently affected by MTM.
|Figure 1: Color fundus photographs of the right (a) and the left (c) eye of the patient showing tessellated appearance with the left eye showing a submacular CNVM. Blue arrows indicate the site of SS-OCT scans. SS OCT scans of the right eye (b) and the left eye (d) show retinoschisis involving the nasal part of the retina in both eyes with the left eye showing CNVM scar (blue arrow). Red arrowhead indicates the schisis at the inner nuclear level. Red star shows the schisis at the level of the nerve fiber layer. Red arrow shows stretched ILM.
