The American Academy of Optometry meeting took place in October, but the 300+ hours of lectures and workshops, symposia, and scientific lecture and poster presentations presented over 4 days has provided a wealth of relevant clinical information, especially in the area of dry eye.
Some of Healio’s recent coverage has highlighted neurostimulation, morning dry eye, Sjögren’s syndrome and omega-3 eye drops.
Neurostimulator increases tear production
Two studies showed that the intranasal tear neurostimulator produced a significant increase in acute tear production. David G. Evans, OD, and colleagues conducted a 1-day crossover study and a 180-day open-label study of Allergan’s TrueTear device.
Morning dry eye may be caused by incomplete lid seal
Patients with dry eye should be asked about symptoms upon waking and evaluated for incomplete lid seal, according to research conducted by Christen Kenrick, OD, FAAO, and colleagues.
Ocular staining worse in dry eye patients with Sjögren’s syndrome
In a study by Barbara Caffery, OD, PhD, FAAO, and colleagues, patients with Sjögren’s syndrome were found to have significantly worse ocular surface and Delphi global staining scores than patients with aqueous deficient dry eye.
Omega-3 eye drop improves ocular dryness symptoms
The use of an eye drop containing ALA omega-3 from flaxseed oil increased the lipid layer thickness and reduced symptoms of dryness 15 minutes after instillation, according to a study from Jennifer Swingle Fogt, OD, FAAO, and colleagues.
