Physicians have to convince patients of the long-term consequences of failing to take glaucoma medication by educating them about the disease and the risk of blindness.
Fort Lauderdale, FL—Multifocal visual evoked potentials (mfVEP) and standard automated perimetry (SAP) perform in a similar manner in eyes with high-risk ocular hypertension or early glaucoma, according to a comparison study. However, agreement between the two techniques reached only 80%, suggesting that they detect different defects in some cases, said Brad Fortune, OD, PhD, associate scientist, Discoveries in Sight, Devers Eye Institute, Portland, OR.
Fort Lauderdale, FL—A modified glaucoma valve made of a porous polymer material reduced outflow resistance in tests conducted in an animal model. The reduced resistance should in turn result in improved control of IOP over conventional implants, explained R. Rand Allingham, MD, at the annual meeting of the Association for Research in Vision and Ophthalmology.
Portland, OR—Seronegative spondyloarthropathies are the most likely group of diseases that ophthalmologists will encounter in their practices, yet many cases will be overlooked if doctors rely on classic textbook definitions of symptoms, according to James T. Rosenbaum, MD, professor of ophthalmology and medicine, Casey Eye Institute, Oregon Health and Science University, Portland.
Philadelphia-In about 80% of glaucoma cases, medication is the preferred initial approach for lowering IOP. However, the choice of medication must be made with the cognition of individual patient differences that can affect the tolerability and effectiveness of the drug, noted Marlene Moster, MD, clinical professor of ophthalmology, Thomas Jefferson Medical Col- lege, Philadelphia.
Fort Lauderdale, FL-Visual function improvement is still apparent and better than ex-pected more than 3 years following the first implantation of a subretinal Artificial Silicon Retina (ASR, Optobionics Corp.) micro-chip in patients experiencing vision loss from retinitis pigmentosa (RP). This degree of improvement could be due at least in part to a neurotrophic effect, said Alan Y. Chow, MD, co-developer of the ASR.
Many of the common complications associated with external silicone punctum plugs, such as extrusion or irritation, can be avoided if physicians take the time to measure the puncta and gauge the correct size, according to representatives of the major manufacturers of these plugs.
Woburn, MA-Advanced Vision Research has joined the growing number of physicians who have concluded that the anti-inflammatory properties of omega-3 fatty acids, such as those found in flaxseed oil, can relieve dry eye. The company recently added a dietary supplement containing these acids, TheraTears Nutrition, to its line of dry eye products.
GenTeal PF, the newest addition to Novartis Ophthalmics' line of dry eye products, is an appropriate choice for patients who must use a true preservative-free drop because they cannot tolerate even the transient preservatives found in some other artificial tears, according to Marguerite McDonald, MD, FACS, clinical professor of ophthalmology, Tulane University, New Orleans.
Los Angeles-Insertion of the Herrick Lacrimal Plug (HLP, Lacrimedics, Eastsound, WA) appears to be trouble-free for the majority of patients, with significant complications wuch as pyogenic granuloma and probing occurring in less than 10% of cases, said John C. Affeldt, MD, MPH.
