[Widefield optical coherence tomography as an effective method for detecting imperceptible flap retinal tears...

Certain late peripheral ruptures after acute posterior vitreous detachment (PVD) may remain undetected during the initial examination of the fundus due to the presence of vitreous hemorrhages and other factors, but they can lead to rhegmatogenic retinal detachment in the future. Hence, it is necessary to conduct an additional thorough examination using optical coherence tomography (OCT) of the vitreoretinal interface periphery in the presence of tear predictors: retinal and vitreal hemorrhages, vitreous pigment cells ("tobacco dust") in the anterior segment of the vitreous body, as well as hyper-reflective dots ("starry sky") in the vitreous body according to OCT scans of patients with acute symptomatic detachment of the hyaloid membrane. The article presents the case of a patient with a clinically imperceptible flap tear detected during acute posterior vitreous detachment. Widefield OCT of the vitreoretinal interface was performed by "sliding" from the center to the periphery of the retina, and revealed a flap tear located next to a dot retinal hemorrhage. OCT scanning of the retinal periphery is an effective modern diagnostic method in the ophthalmological clinical practice.
