A 30-year-old man presented with the complaint of decreased vision in his right eye. He had absent red reflex and the fundus could not be visualized properly. Visual acuity was reduced to 6/12. The patient had occasional problems with his vision for a long time but did not feel the need for a medical review until now. He revealed that he always had cats as pets since his childhood.
His age suggested that congenital cataract, retrolental fibroplasia or retinoblastoma were unlikely. These all cause absent red reflex but are mostly bilateral and present in children aged five years and under. What could be the most probable diagnosis of this condition? *This image based case is from Docplexus editorial team for educative purpose only. Source: Haymarket
