Title: Crystalline Illusion: A Case of Senile Retinoschisis
Description: A 60-year-old male with hypermetropia and senile cataract came for fundus evaluation. This widefield confocal color fundus photograph (iCare EIDON) of the right eye demonstrates bullous, retinoschisis in the inferotemporal quadrant, with a beaten metal appearance of the inner layer, darker blood vessels and shadowing of the vessels. Senile retinoschisis is a condition characterized by the abnormal splitting of the neurosensory layers, primarily the outer plexiform layer, which can resemble retinal detachment. Acquired retinoschisis occurs in 4-22% of individuals over the age of 40. The inferotemporal quadrant is most commonly involved. Most cases of acquired retinoschisis are asymptomatic and remain stationary over time, often requiring no treatment. Outer-layer breaks occur in about 6% of patients with acquired retinoschisis, while inner-layer breaks are less common. The incidence of rhegmatogenous detachment in patients with acquired retinoschisis is estimated to be around 0.05%.
