Epithelial ingrowth protocol guides intervention, therapy
December 1st 2002Nice, France-Although the incidence of epithelial ingrowth as a complication of LASIK is declining, considerable uncertainty remains over when to intervene, according to Arun C. Gulani, MD. In response, Dr. Gulani has devised a grading system to help surgeons answer that question by placing values on the density of the epithelial ingrowth
2002: Specialists pleased with ongoing retinal progress
December 1st 2002Therapies for retinal diseases that re-mained untreatable for decades are seeing major advances. So much so that Jason Slakter, MD, clinical professor of ophthalmology, New York University School of Medicine, and surgeon director, Manhattan Eye, Ear, & Throat Hospital, New York, has proclaimed the first years of the new mil-lennium as the "Decade of the Macula."
CMV retinitis treatment responding to changing HIV therapy
December 1st 2002Editor's Note: HIV/AIDS continues to be a major health problem, not only in the developing world, but in North America and Europe as well. Although the incidence of ocular complications of HIV/AIDS has decreased dramatically since the introduction of highly active anti-retroviral therapy (HAART), the prevalence of HIV positivity continues toincrease, particularly among heterosexual women and minorities.
2002: research confirms benefit of IOP-lowering treatment
December 1st 2002Publication of results from the Ocular Hypertension Treatment Study (OHTS) and the Early Manifest Glaucoma Trial (EMGT) represents two of the most notable events occurring in the field of glaucoma in 2002, but the year is also marked by a number of other significant developments with the potential to influence patient evaluation and management.
Task force suggests new grading scale for diabetic retinopathy
December 1st 2002Orlando-A task force composed of 30 leading ophthalmologists and retinal specialists is recommending the use of a new, five-level classification system for distinguishing degrees of diabetic retinopathy. The results of this effort were highlighted at a news conference held during the American Academy of Ophthalmology (AAO) annual meeting in Orlando.
Expanded applications explored for femtosecond laser
December 1st 2002Carlsbad, CA-The Pulsion FS femtosecond laser keratome (IntraLase Corp., Irvine, CA) appears to be an important new instrument for use in the treatment of lamellar keratoplasty, among others, according to Lee T. Nordan, MD, who described his preliminary results.
Grant funds research: Daniel Albert, MD, wins lifetime achievement prize
December 1st 2002Orlando-Daniel M. Albert, MD, has won the Fight for Sight/Mildred Weisenfeld Award for Lifetime Achievement in Vision Research, which includes a $50,000 grant for research endeavors. The award was presented at the annual meeting of the American Academy of Ophthalmology.
Precision key to effectiveness of custom ablation
November 15th 2002Nice, France-Custom ablation is a useful technique for eyes that have not been treated with a refractive procedure. But this approach can also be used to improve the quality of vision in previously treated eyes that exhibit symptoms such as glare, halos, night vision difficulties, or monocular diplopia, according to Omar J. Hakim, MD, who spoke during the XX Congress of the European Society of Cataract and Refractive Surgeons (ESCRS).
Glaucoma agents effective in reducing diurnal, trough IOPs
November 15th 2002Charleston, SC-When prescribing brimonidine 0.2% b.i.d. as monotherapy for ocular hypertension or primary open-angle glaucoma, physicians should make sure that the drug maintains its effectiveness in the late afternoon and may want to add a third drop to the daily dosage, said William C. Stewart, MD.
Mini shunt diverts excess aqueous humor
November 15th 2002Green Bay, WI-The recently introduced miniature glaucoma shunt (Ex-Press) is an exciting modality with a lot of potential, but this new IOP-lowering treatment still requires further study to define its long-term efficacy and place in the armamentarium of glaucoma management options, said James E. Memmen, MD.
Separate and combined drug therapy both work to lower IOP
November 15th 2002Los Angeles-A randomized, controlled trial comparing the combination therapy dorzolamide-timolol (Cosopt, Merck) with concomitant administration of 2% dorzolamide (Trusopt, Merck) and 0.5% timolol showed that the IOP lowering is equally effective if the drugs are given either in combination or individually.
Once-daily glaucoma therapy better tolerated than b.i.d.
November 15th 2002Houston-In patients with primary open-angle glaucoma (POAG) or ocular hypertension (OH), once-daily treatment with fixed-combination latanoprost/timolol (Xalacom, Pharmacia, Peapack, NJ) is well tolerated and lowers IOP more effectively than twice-daily dorzolamide/timolol (Cosopt, Merck), according to a recent multicenter U.S. study.
IOP-reducing effects of latanoprost, unoprostone weighed
November 15th 2002Baltimore-Latanoprost 0.005% (Xalatan, Pharmacia) taken once daily is more effective in lowering IOP than unoprostone 0.15% (Rescula, Novartis) taken twice daily, according to a recent multicenter study, reported Henry D. Jampel, MD, MHS.
IOP-lowering drug a versatile choice in large-scale study
November 15th 2002Houston-Once-daily bimatoprost 0.03% (Lumigan, Allergan) is a highly effective, safe, and well-accepted IOP-lowering medication across the di-verse population of patients encountered in daily practice, according to the results of a large-scale, com-munity-based, pro-spective, open-label study.
Brimonidine may replace beta-blockers for older patients
November 15th 2002Tucson, AZ-Topical beta-blockers have been a mainstay of ongoing treatment for glaucoma for more than 20 years, but a new study adds to the evidence that they may not be the best option for long-term control of IOP for elderly patients.
