Zika virus-related microcephaly may be associated with retinal, optic nerve damage

SEATTLE — Infants born with microcephaly caused by exposure to the Zika virus may be at risk for retinal and optic nerve damage, according to a speaker here. “Ophthalmologists are well familiar with viral infections of the retina,” Lee M. Jampol, MD, said at the Association for Research in Vision and Ophthalmology meeting. He cited cytomegalovirus, herpes zoster and herpes simplex as endemic viral infections with known ophthalmic consequences that bear some similarities to the Zika virus.

Glucose metabolism affects macular thickness in diabetic patients

SEATTLE — Pericentral macular thickness decreased in diabetic patients with worsening glucose metabolism, which may reflect early neurodegenerative changes, according to a poster presented here. “Macular thinning may be an early sign of diabetic retinopathy and macular thickening may be a sign of diabetic macular edema,” Eline E. De Clerck, MD, and colleagues said in the poster at the Association for Research in Vision and Ophthalmology meeting. “We therefore evaluated to what extent macular thickness differed between individuals with prediabetes and individuals with type 2 diabetes with or without cysts compared with individuals with a normal glucose metabolism.”

Zeiss receives CE mark for PLEX Elite 9000 swept-source OCT system

SEATTLE — The Zeiss PLEX Elite 9000, a novel swept-source optical coherence tomography platform, has received CE mark approval in the European Union, Carl Zeiss Meditec announced in a press release. By providing fast, dense, wide and deep OCT and OCT angiography imaging, the platform “expands researchers’ ability to examine the critical retinal microstructures and microvasculature of the eye at any depth of interest (eg, vitreous, retina and choroid),” according to the release.
