Intravitreal triamcinolone favorable in treating persistent DME
August 1st 2003Fort Lauderdale, FL-In the short term, intravitreal triamcinolone acetonide (4 mg) reduces the risk of progressive loss of vision and commonly improves vision in patients with diabetic cystoid foveal edema that persists after laser treatment, said Mark C.

Skills Exchange program pairs doctors for mutually beneficial relationship
August 1st 2003When Charles A. Kirby, MD, wanted to learn more about expanding his practice with conductive keratoplasty (CK), he did more than read about the procedure and attend seminars. He took a cue from a popular television game show to "phone a friend."
IOL design mimics optic shape change of natural lens
August 1st 2003San Francisco-A novel accommodating IOL (FlexOptic, Quest Vision) designed to mimic the natural crystalline lens through an ability to change optic sphericity is a promising new alternative to treating presbyopia, with the potential for superior efficacy and safety relative to other options for surgical accommodative correction, said John D. Hunkeler, MD, at the American Society of Cataract and Refractive Surgery annual meeting.
Pseudophakic multifocal IOL affords reduced spectacle dependency
August 1st 2003San Francisco-For appropriately selected patients undergoing cataract surgery, implantation of a foldable, multifocal IOL (Array SA40 IOL, AMO) is the best available solution for providing good uncorrected near and distance vision, said Roger Onnis, MD, at the American Society of Cataract and Refractive Surgery annual meeting.
Intravitreal triamcinolone shows promise for CRVO
August 1st 2003Fort Lauderdale, FL-Intravitreal injection of triamcinolone acetonide (Kenalog, Bristol-Myers Squibb) may be a safe and effective treatment for central retinal vein occlusion (CRVO), said Michael S. Ip, MD, at the annual meeting of the Association for Research in Vision and Ophthalmology.
PDT safe choice for eyes with predominantly classic CNV
August 1st 2003Fort Lauderdale, FL-In eyes with predominantly classic subfoveal choroidal neovascularization (CNV) treated with photo- dynamic therapy (PDT) using verteporfin (Visudyne, Novartis Ophthalmics), vision remained stable and the need for additional treatment decreased dramatically over time, reported Peter K. Kaiser, MD, at the annual meeting of the Association for Research in Vision and Ophthalmology.
Transscleral drug delivery system under development
August 1st 2003Fort Lauderdale, FL-Efforts to develop an episcleral anecortave acetate transscleral drug delivery system (AA-TSDDD), targeted for patients with age-related macular degeneration (AMD), are progressing initially in the rhesus monkey as preliminary devices are being redesigned to decrease postoperative problems, said Timothy W. Olsen, MD.
Moxifloxacin hastens resolution of bacterial conjunctivitis
August 1st 2003Fort Lauderdale, FL-A 4-day course of moxifloxacin ophthalmic solution 0.5% (Vigamox, Alcon) is a safe and effective treatment for bacterial conjunctivitis in adults and children as young as 1 month old, according to results from a phase III FDA study, reported Harold R. Katz, MD, who spoke on behalf of the Moxifloxacin Conjunctivitis Study Group at the annual meeting of the Association for Research in Vision and Ophthalmology. The fourth-generation fluoroquinolone received FDA approval in April for the treatment of bacterial conjunctivitis (see related article, Ophthalmology Times, June 1, 2003 issue, Page 1).
Radiotherapy for subfoveal CNV has early, but not durable benefits
August 1st 2003Fort Lauderdale, FL-High-dose (5 3 4-Gy fractions; 6 MeV) external-beam radiation therapy has only a modest and very short-lived benefit in the treatment of subfoveal choroidal neovascularization (CNV) secondary to age-related macular degeneration (AMD), according to an interim analysis of data from the Age-Related Macular Degeneration Radiotherapy Trial (AMDRT).
Multiple-dose regimen safe for neovascular AMD
August 1st 2003Fort Lauderdale, FL-In a phase I, multicenter, randomized trial, the anti-VEGF antibody fragment rhuFab V2 was shown to be safe and well-tolerated in eyes with neovascular age-related macular degeneration (AMD), according to Philip J. Rosenfeld, MD, PhD.
Subretinal device improves visual function in RP patients
August 1st 2003Fort 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.
Hypothesis may explain clinical scenarios in increased ICP
August 1st 2003Editor's Note: Sherif Amer, MD, proposes a new hypothesis for pressure dissociation in optic disc edema due to increased intracranial pressure (ICP) (i.e., papilledema). This theory provides some insight into some of the clinically controversial scenarios that occur in increased ICP such as pseudotumor cerebri without papilledema, asymmetric or frankly unilateral papilledema, and progressive visual loss due to increased ICP without disc edema. The theory has merit and deserves further study and testing of the hypotheses generated. -- Andrew G. Lee, MD
How to... get the most from your optical dispensary
July 15th 2003Vail, CO-Having an optical dispensary in a practice is an excellent way to provide full-service comprehensive eyecare for patients and has the potential to generate significant revenue for the practice, according to ophthalmic practice management specialist James Rienzo.
Limitations of customized ablations deflate "super vision" expectations
July 15th 2003San Francisco-The euphoria associated with customized ablations has finally died down. Refractive surgeons are finding that there are limitations to wavefront technology, such as the cost of equipment, the additional time spent screening patients, and a learning curve for physicians and staff. But there also are limitations to the lasers and wavefront sensors.
Software innovation optimizes functional vision for myopics
July 15th 2003San Francisco-Early LASIKdata for myopic astigmatism using Nidek's NAVEX platform, incorporating the OATz (Optimized Asphe-rical Transition Zone) ablation algorithm, results in exceptional treatment accuracy and quantitative and qualitative vision out-comes, said Arturo Chayet, MD, at the meet-ing of the American Society of Cataract and Refractive Surgery.
