ZEISS Launches First Dual-Speed Swept-Source OCT/OCTA

Left untreated, rhegmatogenous retinal detachment typically results in blindness. Surgical treatment is aimed at preventing fluid access to the subretinal space through the break and eliminating the traction causing the break. The interplay between vitreoretinal traction and predisposing retinal lesions is associated with retinal detachment. Rhegmatogenous retinal detachments are more common, with the primary causes being. posterior vitreous detachment (most common) trauma; Causes of non-rhegmatogenous retinal detachment include tractional and exudative. Tractional retinal detachment occurs when the vitreous pulls the retina, such as from.

Resulting B-scan image showing a radial plane with 12 o’clock in the peripheral fundus at the top of the display, 12 o’clock posterior to the equator in the middle and the optic nerve at the bottom (C, L = lens, V = vitreous, R = retina, S = sclera, ON = optic nerve, O = orbital tissue). A 'V' shaped thick membrane is noted in all quadrants. No after movements are noted in this membrane, indicating retinal detachment. Vitreous membranes are noted with 'v' shaped thick membrane. They show 'after movements'. Another thick membrane is noted outer to retinal detachment on temporal side, indicating choroidal detachment.
