Anterior uveitis present in 18.5% of Ibero-American SpA patients

Anterior uveitis was present in nearly 20% of a large cohort of patients with spondylarthritis in Ibero-American countries and was positively associated with axial involvement and HLA-B27, according to study results.Researchers investigated clinical and demographic variables and disease indices of 2,012 patients with spondylarthritis (SpA) from 85 centers across 10 Ibero-American countries. Fisher’s exact and chi-squared tests were used to compare categorical variables, while ANOVA and Kruskal-Wallis tests compared continuous variables.

Cosmetic eye whitening with mitomycin C poses high complication, retreatment rates

Regional cosmetic conjunctivectomy with postoperative topical mitomycin C with or without bevacizumab injection had high complication and retreatment rates, according to a study.“We recommend longer follow-up of this population that is at risk for future complications and continued search for a better treatment of chronic conjunctival hyperemia,” the study authors said.

Nutritional supplements drive significant improvement in dry eye symptoms, study finds

Postmenopausal patients with moderate-to-severe keratoconjunctivitis sicca may benefit from supplementats with gamma-linolenic acid and omega-3 polyunsaturated fatty acids for treatment of tear dysfunction, according to a study.“Nutritional supplementation with black currant seed oil [gamma-linolenic acid] and fish oil [omega-3 polyunsaturated fatty acids] should be considered in the treatment of tear dysfunction to decrease irritation symptoms and prevent exacerbations in ocular surface inflammation and corneal epithelial disease,” the study authors said.

Phaco-laser trabeculotomy markedly reduces IOP, medication use up to 12 months

Phacoemulsification with excimer laser trabeculotomy reduced IOP and the need for IOP-reducing medications in patients with glaucoma or ocular hypertension, according to a study.“IOP remained significantly reduced from baseline 12 months after phaco-ELT [excimer laser trabeculotomy] regardless of preoperative IOP levels, with no major complications. The IOP reduction remained constant over the entire follow-up,” the study authors said.

Study links refractive error to ciliary muscle thickness in children

Posterior ciliary muscle fibers were thicker in children with myopia, while the apical region of the ciliary muscle was thicker in hyperopes, according to a study.“This is likely the first evidence suggesting that accommodative workload is associated with a specific region of the muscle, which is largely comprised of circular and some radial fibers,” the study authors said.

Aflibercept reduces subfoveal fluid in eyes with persistent exudative AMD

Aflibercept yielded positive anatomic results in cases of exudative age-related macular degeneration that were resistant to ranibizumab or bevacizumab, according to a study.“Visual acuity did not improve. Aflibercept may be beneficial anatomically in cases of exudative AMD treated with persistent fluid on ranibizumab and/or bevacizumab,” the study authors said.

BLOG: Gonioprism simplifies iStent implantation

About a year ago, my partners and I began using the iStent trabecular bypass device shortly after its approval by the U.S. Food and Drug Administration.This wonderful device has changed our thinking about cataract surgery and the glaucoma patient, allowing us to lower pressure in the vast majority of cases with a fairly simple device whose implantation accompanies cataract surgery nicely. I have used it in 25 to 30 patients, including two undergoing Descemet’s stripping endothelial keratoplasty surgery simultaneously with cataract extraction.

Targeted eye care education urged for adults with diabetes

The utilization of eye care among patients with diabetes requires education targeted at financial barriers and comprehension of ophthalmic implications of their disease, according to researchers.“In the United States, Medicare covers an annual eye examination for those with diabetes, and most health insurance covers medical eye examination and payment for eye diseases such as diabetic retinopathy, cataract, and glaucoma. However, 25% to 47% of those with diabetes do not have yearly eye examinations,” Chiu-Fang Chou, DrPH, of the division of diabetes translation at the National Center for Chronic Disease Prevention (Read more...)

Measure to fix physicians’ Medicare reimbursement formula now estimated to cost $175 billion

The cost to replace Medicare’s existing payment formula for physicians now is estimated at $175 billion, $37 billion more than previously projected, according to the latest report from the Congressional Budget Office.Because the current reform proposal (H.R. 2810) — in late July by the House Energy and Commerce Committee — does not include any details on how to pay for itself, the Congressional Budget Office (CBO) estimate is the benchmark lawmakers will use as they debate ways to save enough money elsewhere to fund a replacement for Medicare’s sustainable growth (Read more...)

Corneal hysteresis strongly associated with glaucoma progression, study finds

Corneal hysteresis correlated significantly with an elevated risk of glaucoma progression, according to a study.“Eyes with lower hysteresis had faster rates of visual field loss than those with higher hysteresis,” the study authors said. “An eye with a more deformable cornea could have an optic disc that is more susceptible to IOP damage.”
