Neuroprotection is a concept that originated in the CNS community with the development of therapies aimed at preventing or retarding the manifestations of disorders such as Parkinson's and Alzheimer's diseases, stroke, and head trauma. Less than 15 years ago, the ophthalmic community began to discuss this concept as a novel way to preserve vision in disorders of the retina.

Presumed ocular histoplasmosis syndrome (POHS) is characterized by a classic triad of discrete atrophic choroidal scars in the macula or midperiphery, known as "histo spots"; peripapillary atrophy; and choroidal neovascularization (CNV). It occurs bilaterally in about 60% of patients.

Fort Lauderdale, FL-Patients undergoing elective phacoemulsification can be discharged the same day and return for follow-up 2 weeks later, achieving the same results as those also seen 1 day postop, according to Christopher Tinley, MB, ChB, at the annual meeting of the Association for Research in Vision and Ophthalmology.

Fort Lauderdale, FL-Estrogen-whether endogenous or from hormone replacement therapy (HRT)-appears to help prevent cataract formation, according to Australian researcher Christine Younan, MD, who reported her findings at the annual meeting of the Association for Research in Vision and Ophthalmology.

Dorado, Puerto Rico-Cataract and other major surgeries made up a large part of ophthalmologists' practice revenue in 1995. Clinical services also contributed substantially to the bottom line. But over the last 7 years, surgeons have seen a decline in both these areas, noted practice management consultant James Rienzo.

Ottawa-Thanks to advances in techniques and technology, surface ablation with PRK or LASEK for eyes with low-to-moderate refractive errors yields visual outcomes equivalent to LASIK with lower risks of vision-threatening complications and fewer re-treatments, said W. Bruce Jackson, MD.

Fort Lauderdale, FL-Vitrectomy with retinal vein cannulation and infusion of tissue plasminogen activator (t-PA) is a relatively safe procedure that improves vision in patients with central retinal vein occlusion (CRVO) or hemispheric retinal vein occlusion (HRVO), according to Jeffrey N. Weiss, MD.

Fort Lauderdale, FL-A newly developed high-speed optical coherence tomography (OCT) system for recording 3-D images of the human retina promises to be a valuable tool for the diagnosis of retinal diseases, said Christoph K. Hitzenberger, PhD, associate professor of medical physics at the Institute of Medical Physics, University of Vienna, Austria.

Irregular astigmatism, one of the most frequent complications of corneal refractive surgery, was relatively unnoticed and underestimated until video keratography showed that some irregular astigmatism is present in as high as 40% of patients who have undergone corneal refractive surgery.1

Vancouver, British Columbia-Surgeons treating patients with high degrees of hyperopia should consider performing a procedure other than PRK because of the development of apical scarring with potential subsequent severe vision loss, according to Simon P.

Philadelphia-The performance of glaucoma medications in phase III FDA trials may not reflect their performance in a real-world clinical setting, according to researchers at Wills Eye Hospital.

Two glaucoma drugs approved last year, travoprost (Travatan, Alcon) and bimatoprost (Lumigan, Allergan), are associated with higher rates of hyperemia than the more established drug latanoprost (Xalatan, Pharmacia). However, the hyperemia is seldom a clinically significant side effect, according to a sampling of physicians who are familiar with all three drugs.
