American Academy of Ophthalmology, Nov. 10-13, 2012Last Updated: November 16, 2012.
The annual meeting of the American Academy of Ophthalmology was held from Nov. 10 to 13 in Chicago and attracted approximately 6,000 participants from around the world, including ophthalmologists, optometrists, opticians, and other eye health care professionals. The conference featured presentations focusing on the latest advances in comprehensive eye care, including medical, surgical, and optical care.
In one study, Daniel Roth, M.D., of the Robert Wood Johnson Medical School in Piscataway Township, N.J., and colleagues found that the iPad provided high contrast and increased brightness that was helpful to patients who had near vision issues associated with macular degeneration.
"We compared the near vision of patients using the Rosenbaum near vision test as compared to a near vision chart on the iPhone and found that vision was improved with the iPhone," Roth said. "We then tested reading in a cohort of patients, using a newspaper versus the same newspaper on an iPad. We found a statistically significant increase in reading speed using the iPad. We further assessed the same factors when we increased the reading font on the iPad to 18 point and found that reading speed further increased as compared to the traditional 12-point font on the iPad."
The investigators also assessed changes in reading speed and near vision problems using the original Kindle (the original Kindle does not have a back-lit screen).
"We compared the Kindle (12-point and 18-point font), iPad (12-point and 18-point font), and regular book. We found a statistically significant increase in reading speed using the iPad for both 12-point and 18-point fonts as compared to the regular book and original Kindle," Roth said. "Overall, the iPad provides high contrast and increased brightness that helps patients with near vision issues. Therefore, physicians may recommend the use of an iPad for patients with macular degeneration with near vision issues, as the high contrast and increased brightness can help improve near vision tasks and reading speed."
In another study, Zachary Roth, M.D., of the Albany Medical Center in New York, and colleagues preformed a retrospective chart review among children who had been referred for or had primary compliant of headache.
"We followed the children until headache resolved and then subdivided the patients into those who needed glasses or a change in lenses and those who did not. We found that refractive error did not seem to play a significant role in headaches. In the end, those who required refractive correction did just as well in regards to headache resolution as those who didn't," Roth said. "As far as clinical impact, I think this helps to confirm something many ophthalmologists anecdotally know to be true, that among the many causes of headaches, the eyes are rarely the culprit."
Shiho Kunimatsu-Sanuki, M.D., of the Tohoku University Graduate School of Medicine in Sendai, Japan, and colleagues evaluated whether visual field loss correlates with frequency of motor vehicle collisions in advanced glaucoma patients. The investigators developed a driving simulator to be used by patients with visual field loss. To ensure consistency in speed and driving technique, the investigator's simulator controlled the speed and steering automatically.
"There were no differences between the patients with advanced glaucoma and the normal controls in number of motor vehicle collisions in the last five years. Previous studies examining motor vehicle collision cases in the last five years did not show how seriously advanced glaucoma affected normal control of driving. But using our driving simulator, we found significant differences between the patients and the normal controls in collision frequency," Kunimatsu-Sanuki said. "Integrated visual field (binocular visual field) sensitivities within 10 degrees of the fixation point may have been related to broadside collisions and collisions with oncoming right-turning vehicles."
AAO: Microstent Cuts Intraocular Pressure in Glaucoma
TUESDAY, Nov. 13 (HealthDay News) -- For patients with mild-to-moderate open-angle glaucoma, implantation of a nickel titanium microstent (Hydrus Microstent) is associated with significant reduction in intraocular pressure, which is maintained at one year, according to a study presented at the annual meeting of the American Academy of Ophthalmology, held from Nov. 10 to 13 in Chicago.
AAO: Sound Therapy Reduces Anxiety in Cataract Surgery
MONDAY, Nov. 12 (HealthDay News) -- For patients undergoing cataract surgery, a binaural beat-music mix or music-only intervention correlates with less anxiety and reduced systolic blood pressure, according to a study presented at the annual meeting of the American Academy of Ophthalmology, held from Nov. 10 to 13 in Chicago.
