Latest OCT advances improve diagnosis, management of peripheral vitreoretinal pathologies

FORT LAUDERDALE, Fla. — Widefield imaging and ultra-widefield imaging have acquired an increasingly important role in screening, diagnosing, monitoring and treating retinal diseases.
“Back in 1984, Oleg Pomerantzeff first described widefield retinal imaging with a 90° noncontact camera, and this began the successful quest for imaging the posterior pole. The Optos multimodal [ultra-widefield] device was a game changer, and ultra-widefield OCT is now essentially in every retina clinic,” Paulo E. Stanga, MD, said at the Retina World Congress.
Traditional retinal examination with slit lamp biomicroscopy alone is no longer considered an adequate method for assessing the status of the retina because peripheral pathologies may go unnoticed, possibly leading to serious loss of vision or even blindness, he said.
“Navigated single-capture 3D and cross-sectional [widefield] swept-source OCT provide detailed anatomic information of the mid and peripheral neuroretina and vitreoretinal interface, allowing early recognition of vision-threatening features that may influence clinical management, particularly in an era of telemedicine or when there is limited or no access to indirect ophthalmoscopy with 360° scleral indentation,” Stanga said.
He has been using these technologies since 2012, and he recently published in the European Journal of Ophthalmology his experience with 148 eyes of 74 patients.
“We can consider the diagnosis of peripheral vitreoretinal pathologies and [posterior vitreous detachment] in the symptomatic as well as in the fellow eye a landmark achievement. Navigated single-capture 3D and cross-sectional [widefield] swept-source OCT is a powerful diagnostic tool, able to provide high-quality, clinically meaningful images which can change clinical management in several cases,” Stanga said.
