Profiling: Defining the link between quality, cost of care
June 1st 2009Health insurance payers are rating their providers by the efficiency of the care delivered, and are beginning to steer patients to the most cost-effective care providers. However, cost-effectiveness does not always equate to high quality, and there are a number of potential problems inherent in the insurance companies' methodologies that make this a disturbing trend for physicians.
Azithromycin shown to work quickly to improve anterior, posterior blepharitis
June 1st 2009Azithromycin ophthalmic solution 1% (AzaSite, Inspire Pharmaceuticals), a broad-spectrum antibiotic that has the propensity to penetrate into the ocular tissues, rapidly improves anterior blepharitis faster than any other treatments for blepharitis, according to one ophthalmologist.
Giant cell arteritis focus of regional study
June 1st 2009The electronic database of a large health-maintenance organization was used to identify patients who had a positive temporal artery biopsy indicating a diagnosis of giant cell arteritis (GCA). The calculated incidence of GCA was significantly less than previously reported and is thought to reflect, in part, differences in population demographics between studies.
Giant cell arteritis: An updated review
June 1st 2009This article summarizes the recent elucidations on the immunopathogenic process that leads to giant cell arteritis (GCA) and reviews both the well-known and newly recognized clinical subtypes and manifestations of the disease. The role of various noninvasive imaging techniques that are increasingly used to corroborate a clinical diagnosis of GCA as well as traditional and new treatment strategies are discussed.
Topical nepafenac efficacy is suggested by retrospective study
June 1st 2009A retrospective study analyzed outcomes in 18 patients who were treated for idiopathic or post-cataract surgery cystoid macular edema with nepafenac 0.1% (Nevanac, Alcon Laboratories) alone or combined with a corticosteroid. Statistically significant improvements were achieved in mean visual acuity and foveal thickness in both groups.
Difluprednate effectiveness is evaluated when administered four times daily
June 1st 2009Difluprednate ophthalmic emulsion 0.05% (Durezol, Sirion Therapeutics) was at least as effective as prednisolone acetate suspension 1% (Pred Forte, Allergan), dosed twice as often, in the treatment of endogenous anterior uveitis. Equivalent effectiveness with less-frequent dosing could improve patient compliance, according to one ophthalmologist.
Bromfenac trial suggests possibility of twice-daily corticosteroid dosing
June 1st 2009A prospective, randomized, investigator-masked study was conducted to compare twice-daily and four-times-daily dosing of a corticosteroid after cataract surgery. All patients also received bromfenac 0.09% (Xibrom, Ista Pharmaceuticals). No significant differences in macular thickening or anterior chamber cell and flare were observed between groups.
Levofloxacin 1.5% shows significant aqueous penetration at three of four time points
June 1st 2009An active comparator, parallel group study comparing levofloxacin 1.5% and moxifloxacin 0.5% in patients undergoing cataract surgery showed significantly greater aqueous penetration of levofloxacin, measured as area under the curve over a 6-hour interval. Levofloxacin also had a significantly higher Cmax and significantly higher maximum concentration at the end of the dose interval. These findings indicate a possible role for levofloxacin in the prophylaxis of endophthalmitis at the time of cataract surgery.
Besifloxacin effective against corneal bacteria
June 1st 2009Besifloxacin (Optura, Bausch & Lomb) was found to be more effective than gatifloxacin and moxifloxacin in reducing the number of methicillin-resistant Staphylococcus aureus organisms in the cornea when applied topically 10 to 18 hours after infection.
Loteprednol/tobramycin yields comfort, tolerability
June 1st 2009Loteprednol etabonate 0.5%/tobramycin 0.3% ([LE/T]; Zylet, Bausch & Lomb) was found to be superior to dexamethasone 0.1%/tobramycin 0.3% ([DM/T]; Tobradex, Alcon Laboratories) in a comparison study that tested ocular comfort and tolerability in healthy volunteers. LE/T also has shown to be less likely to cause increases in IOP levels compared with DM/T. LE/T may provide some small advantages, possibly resulting from formulation differences and/or the steroid used, the researchers concluded.

May 13th 2009Gary Conrad, PhD, has received a 4-year grant renewal of $1.48 million from the National Eye Institute for the National Institutes of Health (NEI/NIH) to study the cornea. Dr. Conrad is a university distinguished professor at Kansas State University's Division of Biology.
Study compares M-SICS, phaco in charity camp population
May 1st 2009To answer the question of whether quality - specifically, uncorrected vision, astigmatism, visual rehabilitation, and safety - is sacrificed when M-SICS is performed instead of phaco, Sanduk Ruit, MD, Geoffrey Tabin, MD, David F. Chang, MD, and colleagues conducted the first prospective, randomized trial of phaco versus M-SICS in a charity camp population.
Cyclosporine for dry eye shows significant improvement in symptoms, according to phase II study
May 1st 2009Phase II of a clinical study examining a formulation of cyclosporine (Cyclokat, Novagali Pharma) has been completed, and results demonstrate statistically significant improvement with signs and symptoms in patients suffering from moderate-to-severe dry eye syndrome.
Perimetry software measures functional progression of glaucoma using trend, event analyses
April 15th 2009The newest version of proprietary software (Guided Progression Analysis, Carl Zeiss Meditec) to measure the functional progression of glaucoma combines event and trend analyses and enables faster, more quantitative evaluation of change in visual field than that permitted by older methods, according to one ophthalmologist. Use of the software requires a particular, newer perimeter (Humphrey Field Analyzer II-i, Carl Zeiss Meditec), and clinical correlation is advised.
SD-OCT provides improvement in imaging compared with TD-OCT
April 15th 2009Spectral-domain optical coherence tomography (SD-OCT) represents an improvement in imaging compared with time-domain OCT and, therefore, the potential for improved patient care. Proprietary technology (3D OCT 1000, Topcon Medical Systems) is easy to use and has versatile software, according to one ophthalmologist. The choice of any SD-OCT unit, however, must be based on an analysis of an individual practice's needs.

April 15th 2009Results of a study using a non-contact applanation tonometer (Ocular Response Analyzer, Reichert) to evaluate keratoconic eyes during and after corneal collagen crosslinking demonstrate changes in tonometer measurements that are consistent with changes in corneal thickness, hydration, and regularity.
Patient has decreased vision, photophobia
April 15th 2009A 26-year-old African American female presented to the Bascom Palmer Eye Institute emergency room with complaints of progressively decreasing vision in both eyes over the past 2 weeks associated with numbness on the right side of her face and mouth. She also had symptoms of light sensitivity but denied flashes, floaters, or other ocular symptoms. She denied any other recent illnesses, drug usage, exposure to parasites, infections, or risk factors for HIV.
Physician still most important 'diagnostic imager'
April 15th 2009The clinical exam remains the key to ophthalmologists' decision-making related to the diagnosis and determination of progression of glaucoma. "Baseline" technology in ophthalmology practices includes the slit lamp, some lenses, a gonio prism, an automated perimeter, a pachymeter, and optic nerve imaging capability. Other technology, however-such as confocal scanning laser ophthalmoscopy; nerve fiber layer imaging devices capable of scanning laser polarimetry and optical coherence tomography (OCT); and some anterior segment imaging technologies, including ultrasound biomicroscopy and anterior segment OCT-do not yet have absolute sensitivity and specificity and serve as aids to, not replacements for, the ophthalmologist.
