Nanotechnology targets degenerative cascades in retina

LAS VEGAS — Nanotechnology can be used to restore visual function at a molecular or cellular level, a speaker said at the American Academy of Ophthalmology meeting.Artificial photoreceptors and free radical scavengers can be used to restore vision in patients with macular degeneration, retinitis pigmentosa and other chronic diseases, Emmanuel Chang, MD, PhD, said during a press briefing on “Innovations in vision: Nanotech, nearsightedness and neuro-ophthalmology imaging.”

Young child referred for difficulty seeing in the dark

A 5-year-old boy was referred to the retina service for progressively worsening night vision that began approximately 6 months before presentation. He denied changes in vision in well-lit settings, eye pain, redness, new floaters, photopsias and headaches. He had no history of trauma.His ocular history was remarkable for mild astigmatism not requiring correction. His medical history was remarkable for asthma, sinusitis and an equivocal work-up thus far for von Willebrand’s disease, which his mother has. He was born full-term without complications during the pregnancy or delivery. There was a family history of night vision difficulties, including his mother and grandmother. His maternal uncle was legally blind.

Surgeon experience affects choice of intervention for symptomatic floaters

Vitreoretinal surgeons may be more likely to intervene for symptomatic floaters if they have performed pars plana vitrectomy for floaters in the past and perform more vitrectomies each year, according to a study.Symptomatic floaters can interfere with daily functioning and affect patients’ quality of life. Either Nd:YAG vitreolysis or pars plana vitrectomy can be performed to treat this problem, but there is controversy whether retina specialists should proceed with surgical intervention in otherwise healthy eyes.
