A 5-month-old term infant with delayed milestones referred by a neonatologist was examined at the vision center using a pediatric fundus camera (3nethra Neo, Forus Health, India)[1] during the COVID-19 (coronavirus disease 2019) pandemic in rural west Uttar Pradesh, India. History of consanguinity was present. A cherry-red spot was noticed at the posterior pole in both eyes.[2] The patient was sent back and magnetic resonance imaging and blood tests were done that revealed white matter demyelination in the periventricular area and decreased level of hexosaminidase A and B (quantitative GM2 gangliosidosis 55.79 nmol/mg)[3] suggestive of Tay–Sachs disease. Telemedicine while bridging the health care gap in the rural–urban divide, bridged the gap between the suspicion and the diagnosis, too [Fig. 1].
