Las Vegas—Ocular allergies affect up to 40% of the pediatric population, and this high prevalence has ramifications beyond providing symptom relief, said Terry Kim, MD, during a continuing medical education symposium here at the annual meeting of the American Academy of Ophthalmology.
Las Vegas—Identification and pretreatment of allergy patients can improve refractive surgical outcomes, said Deepinder K. Dhaliwal, MD, at a continuing medical education symposium at the American Academy of Ophthalmology annual meeting. About 20% to 30% of refractive surgery patients have associated allergies, she added.
Las Vegas—Steady-state visual evoked potential (SSVEP) is a promising research tool for vision assessment in the preverbal patient and one that is being used increasingly in the clinic, said William V. Good, MD, who discussed his research here during the annual meeting of the American Academy of Ophthalmology.
Las Vegas—Studies of a 790-nm titanium-sapphire laser (SOLX 790, OccuLogix) used to perform trabeculoplasty in human donor eyes and in patients suggest that the laser may be an important tool for treatment of open-angle glaucoma due to benefits such as an IOP-lowering effect, low complication profile, and ability to repeat treatment periodically, according to Gabriel Simon, MD, PhD. He presented a poster on the findings of his research here at the annual meeting of the American Academy of Ophthalmology in Las Vegas.
Las Vegas—Studies have found conflicting evidence that sleep apnea is a risk factor for glaucoma, with variable control groups and variability in defining sleep apnea and glaucoma contributing to the disagreement. Parag A. Gokhale, MD, speaking here at the annual meeting of the American Academy of Ophthalmology, said he sides with those who believe that a positive association exists between the two conditions.
Las Vegas—Laboratory experiments involving an overpressurization technique have demonstrated that acoustic transient cavitation is necessary to produce efficient phacoemulsification, according to Mark E. Schafer, PhD, speaking here at the annual meeting of the American Academy of Ophthalmology (AAO).
The shunt takes advantage of the naturally occurring pressure differential between the anterior chamber and the suprachoroidal space.
Las Vegas—Primary acquired melanosis (PAM) of the conjunctiva is an uncommon but important disease. Although some studies have suggested that it occurs in as much as one-third of the population, most cases do not need treatment. The disease is potentially malignant, however, and arguments can be made for early treatment if risk factors are present, said Jerry A. Shields, MD, in his delivery of the Lorenz E. Zimmerman Lecture here at a combined meeting of the American Academy of Ophthalmology and the American Association of Ocular Pathologists.
London—In a comparison of visual outcomes with the femtosecond laser and mechanical microkeratomes following LASIK, both were very effective at targeting emmetropia. Eyes treated with the femtosecond laser, however, had faster visual recovery and better uncorrected visual acuity (UCVA) results at 3 months despite experiencing more transient symptoms immediately after surgery, reported Capt. Steve Schallhorn, MD, here at the XXIV Congress of the European Society of Cataract and Refractive Surgeons.
London—One-year data from an eye-to-eye comparison study of the IntraLase femtosecond laser (IntraLase Corp.) versus the Hansatome mechanical microkeratome (Bausch & Lomb) in myopic LASIK with the VISX Custom-Vue platform (Advanced Medical Optics/VISX) showed that refractive outcomes in both of the groups were excellent and identical despite clinically and statistically significant differences favoring the femtosecond laser earlier in the study.
