Initial treatment for lid wiper epitheliopathy effective
August 15th 2006Fort Lauderdale, FL-Both a corticosteroid (loteprednol etabonate ophthalmic suspension, Lotemax, Bausch & Lomb) and an oil-in-water emulsion (Soothe Emollient Eye Drops, Alimera Sciences) effectively minimized or eliminated lid wiper epitheliopathy findings and symptoms during an initial treatment period of 5 to 10 weeks. The oil-in-water emulsion regimen without corticosteroids controlled lid wiper epitheliopathy findings and symptoms in an extended 1-year study.
Mast cell stabilizer offers daily relief for allergy sufferers
August 15th 2006Boston-With the advances in anti-allergy medications that have taken place in the recent past, nedocromil sodium ophthalmic solution 2% (Alocril Ophthalmic Solution, Allergan) fills a niche for those patients who do not find relief with the newest combination antihistamine/mast cell stabilizers, Mich?l Raizman, MD, told Ophthalmology Times.
Pediatric ocular allergy can be alleviated
August 15th 2006Chicago-High allergen counts this season combined with increased parental awareness about the potential functional impact of allergic conjunctivitis are leading to an increase in the number of pediatric patients being seen for control of ocular allergy.
Dry eye symptoms return with cyclosporine cessation
August 15th 2006San Francisco-Discontinuing the use of cyclosporine ophthalmic emulsion 0.05% (Restasis, Allergan), the only FDA-approved drug to treat dry eye, may result in recurrence of the signs and symptoms of keratoconjunctivitis sicca (KCS), and reinstitution of the drug is needed to reverse those signs and symptoms, John Sheppard, MD, reported at the annual meeting of the American Society of Cataract and Refractive Surgery.
Topical allergy agents keep ocular surface safe
August 15th 2006Commonly used systemic antihistamines taken for seasonal allergies can cause ocular surface drying that in turn aggravates ocular allergy symptoms. Antihistamine drops specifically formulated for ocular allergies, in contrast, do not appear to decrease tear volume or tear flow or cause ocular surface damage, according to several investigators who have studied ocular drying. However, in a separate mouse study, topical ocular allergy medications themselves may have different effects on tear volume or tear flow.
Effects of dry eye therapy continue after treatment stopped
August 15th 2006San Francisco-The effects of Systane lubricant eye drops (Alcon Laboratories) persist for about 3.5 weeks after the treatment is stopped, according to James McCulley, MD. At that time, the signs and symptoms of dry eye increase significantly compared with the baseline values when the patients were still being treated with the eye drops.
Flaxseed oil helps to prevent dry eye after LASIK
August 15th 2006San Francisco-Flaxseed oil seems to be as effective as doxycycline in preventing the development of dry eye after LASIK. Colin C.K. Chan, MD, speculated that the reason may be due to its anti-inflammatory and lipid-modifying properties. He presented his ideas at the annual meeting of the American Society of Cataract and Refractive Surgery.
Deeper understanding of dry eye surfaces
August 15th 2006Houston-While dry eye disease has been known to cause ocular surface damage, researchers did not understand how this happened until recently. For a long time, ocular surface damage was attributed to the drying effect of the disease, but the use of artificial tears did not improve the situation. Researchers now know that inflammation is a key component of dry eye disease leading to ocular surface problems, reported Stephen C. Pflugfelder, MD.
Retina center teams up with high school student
August 15th 2006Fort Myers, FL-Last year Sabrina Prabakaran, a high school student at Canterbury School, met with the Retina Health Center team to discuss a research project to investigate further the value of bevacizumab (Avastin) in the treatment of wet age-related macular degeneration (AMD). The drug is currently approved for the treatment of colon cancer. The research project is now complete, and the findings show that nearly half of patients with AMD and taking bevacizumab showed improvement in vision.

Tracking challenges after laser flap creation not insurmountable
August 15th 2006San Francisco-Tracking acquisition using the closed-loop eye-tracking system on the LADARVision excimer laser platform (Alcon Laboratories) may be more difficult in eyes that have undergone flap creation with the femtosecond laser (IntraLase Corp.), but can be readily accomplished through the use of some simple, special maneuvers, said Dan B. Tran, MD, at the American Society of Cataract and Refractive Surgery annual meeting.

August 15th 2006San Francisco-Multifocal wavefront-guided ablation with CustomVue (Advanced Medical Optics [AMO]/VISX) for hyperopic presbyopia is associated with favorable safety, stability, and high patient satisfaction with vision, according to the 1-year results of an international treatment trial.
Age a factor in keratoconus complications
August 15th 2006Fort Lauderdale, FL-Younger age appears to be associated with the development of corneal scarring, corneal steepening, and the need for penetrating keratoplasty in patients with keratoconus, according to a study conducted by Karla Zadnik, OD, PhD.
Ocular rosacea harder to detect in dark-skinned patients
August 15th 2006San Francisco-Ocular rosacea is not a rare disease, but it can be missed easily in individuals with dark skin. Because this can be a sight-threatening disease, ophthalmologists should pay added attention to patients who present with ocular irritation and chronic severe meibomitis, explained Nibaran Gangopadhyay, MS, who described the clinical features and how best to manage the disorder at the annual meeting of the American Society of Cataract and Refractive Surgery.
