Berlin unites ophthalmologists from the East and West
August 1st 2008Berlin, Germany, will host the XXVI Congress of the European Society of Cataract and Refractive Surgeons from Sept. 13 to 17. The annual meeting will feature a diverse agenda that includes symposia, a workshop on visual optics, training courses, and exhibits.
Long-term use of ranibizumab appears safe, well tolerated for wet age-related macular degeneration
August 1st 2008Neovascular age-related macular degeneration treated with long-term use of intravitreal ranibizumab (Lucentis, Genentech) was safe and well tolerated in a group of patients participating in an extension study. Between the original studies and the extension trial, patients were followed for approximately 4 years, during which no safety signals were observed. Although problems linked to vascular endothelial growth factor inhibition were suggested, the lack of a control group makes proving a correlation difficult.
Vitrectomy beneficial with retained lens fragments
August 1st 2008An immediate vitrectomy should be considered in patients with retained intravitreal fragments of the crystalline lens after complicated cataract surgery. Eyes that underwent immediate vitrectomy had better visual acuity and a lower retinal detachment rate than eyes that underwent delayed vitrectomy.
Initiative aims to educate primary care physicians better about intraoperative floppy iris syndrome
August 1st 2008Before prescribing alpha blocker treatment, a primary care physician (PCP) should consider involving the cataract surgeon when treating a patient with a known diagnosis of cataract. So says an educational statement that is part of an initiative by the American Society of Cataract and Refractive Surgery and the American Academy of Ophthalmology launched to further educate PCPs about the connection between alpha blockers, such as tamsulosin (Flomax, Boehringer Ingelheim Pharamceuticals), and intraoperative floppy iris syndrome during cataract surgery.
Intraoperative floppy iris syndrome continues to challenge cataract surgeons, survey finds
August 1st 2008Results of a recent survey by the American Society of Cataract and Refractive Surgery Cataract Clinical Committee provide insight into the clinical issues facing cataract surgeons and their patients taking alpha blocker drugs. Intraoperative floppy iris syndrome continues to challenge cataract surgeons and especially seems to be associated with tamsulosin (Flomax, Boehringer Ingelheim Pharmaceuticals), according to respondents.
Water-tight wound closure paramount for reducing risk
August 1st 2008To reduce the risk of endophthalmitis after cataract surgery a multimodal approach is needed. Assuring a water-tight wound closure without the use of stromal hydration and use of a fourth-generation fluoroquinolone are two important factors. An analysis of data from patients undergoing clear corneal cataract extraction at the University of Texas Southwestern Medical Center supports these recommendations.
Congress blocks pay drop, but 21% cut looms in 2010
August 1st 2008Congress was able to block a pay cut for physicians who serve Medicare patients. Even though the American Society of Cataract and Refractive Surgery (ASCRS) and the American Academy of Ophthalmology (AAO) are pleased for the delay in the pay cut they maintain that the hard work is just beginning.
Vitrectomy beneficial with retained lens fragments
August 1st 2008An immediate vitrectomy should be considered in patients with retained intravitreal fragments of the crystalline lens after complicated cataract surgery. Eyes that underwent immediate vitrectomy had better visual acuity and a lower retinal detachment rate than eyes that underwent delayed vitrectomy.
Laser may be better than corticosteroids for treating diabetic macular edema
July 30th 2008When treating diabetic macular edema (DME), the conventional laser treatment may be more effective than the newer drug therapy used to treat abnormal swelling around the eye, according to a National Eye Institute (NEI) study.
AAO names August cataract awareness month, urges those at risk to see their ophthalmologist
July 28th 2008The American Academy of Ophthalmology (AAO) has named August Cataract Awareness Month to remind those at risk for cataracts to see their ophthalmologist to determine whether they have a cataract and if it should be removed.
In vivo test of contact lens IOP monitor shows device's promise for glaucoma management
July 15th 2008The first in vivo tests of a wireless, soft contact lens sensor demonstrate that the device's measurements correspond with those taken via Goldmann tonometry. The contact lens sensor, which is designed to detect the tiny changes in corneo-scleral curvature induced by IOP changes, could be used potentially to monitor a patient's IOP changes over 24 hours.
Many important clinical outcomes a product of OHTS
July 15th 2008The long-running Ocular Hypertension Treatment Study has produced many important clinical findings. Among them is the conclusion that African-American and white patients have similar responses to treatment with topical beta-blockers and prostaglandin analogs. The study also found that optic disk hemorrhages are a risk factor for progression from ocular hypertension to primary open-angle glaucoma.
AAO preferred practice patterns often overlooked
July 15th 2008A retrospective chart review of 200 charts from three centers found that physicians do not adhere consistently to the American Academy of Ophthalmology's Preferred Practice Patterns for glaucoma management. As the world's leading cause of irreversible blindness, the stakes are high to ensure that the patterns are being followed to maximize positive outcomes for patients with glaucoma.
In vitro studies aim to characterize retinal cell safety profiles of intravitreal medications
July 15th 2008In vitro studies using retinal neurosensory and pigment epithelial cell lines in culture are aiming to define the relative safety profiles of combination corticosteroids and anti-vascular endothelial growth factor (VEGF) agents being considered for intravitreal treatment of retinal diseases.
When good blebs go bad: remodeling a filtering bleb
July 15th 2008It is possible to remodel filtering blebs, but much like a home remodeling project, a bleb remodeling should only be undertaken with a plan, a careful review of options, and the realization that it may become more involved than initially expected.
Combination therapy shows promise for AMD
July 15th 2008Combination therapy to treat age-related macular degeneration seems to be a promising avenue of research. The gain in visual acuity can be sustained with fewer intravitreal injections. This approach might also reduce the overall cost of treatment.
Systemic complications of intravitreal VEGF explored
July 15th 2008The systemic complications associated with anti-vascular endothelial growth (VEGF) factor therapy for colon cancer are well documented. Those associated with intravitreal injection of anti-VEGF agents to treat neovascular age-related macular degeneration (AMD) seem to occur infrequently. Monitoring of these events has been limited thus far, however. Good methods need to be developed for post-marketing surveillance of anti-VEGF agents used to treat patients with AMD.
OCT-guided re-treatment of neovascular AMD preserves drug benefits with fewer injections
July 15th 2008The 2-year results of the PrONTO Study indicated that intravitreal injections of ranibizumab (Lucentis, Genentech) produces rapid improvements in visual acuity (VA) and optical coherence tomography (OCT) outcomes in patients treated for neovascular age-related macular degeneration. The changes on OCT are visible before the changes in VA and allow ophthalmologists to determine each patient's need for additional dosing of ranibizumab.
Sustained-release insert has multitude of applications
July 15th 2008A hydroxypropyl cellulose ophthalmic insert (Lacrisert, Aton Pharma), a once-daily, preservative-free insert that helps to retain moisture, stabilize the tear film, lubricate the eye, and increase tear break-up time, may be beneficial in the treatment of patients with dry eye due to lid function abnormalities, closure problems, or thyroid disease.
Assessment of antimuscarinic activity of topical and oral antihistamines
July 15th 2008Out of seven anti-allergy medications examined in a laboratory study epinastine is a potent antihistamine but has minimal anticholingeric activity. Ideally, allergy medication should effectively target the histamine receptors without causing adverse effects such as ocular dryness.
Crossover study results favor topical corticosteroid in management of allergic conjunctivitis
July 15th 2008Loteprednol etabonate ophthalmic suspension 0.2% and olopatadine HCl ophthalmic solution 0.1% were compared in a study for the treatment of allergic conjunctivitis. After 14 days of use, the topical corticosteroid demonstrated greater efficacy in improving Ocular Surface Disease Index scores and was preferred by a significantly higher proportion of patients. Both medications were safe and well tolerated, and both led to improved signs and symptoms.
Artificial tear delivers high-performance dry eye therapy
July 15th 2008A new high-performance artificial tear product (Systane Ultra, Alcon Laboratories) was created with an intelligent delivery system designed to maximize comfort upon instillation and provide sustained symptomatic relief and ocular surface protection.
Dry eye disease: have we found the perfect diagnostic?
July 15th 2008Tear hyperosmolarity is central to the dry eye disease process and the value of measuring tear osmolarity in the diagnosis of dry eye disease is well established. Alan Tomlinson, PhD, DSc, FCOptom, and Michael A. Lemp, MD, discuss the obstacles that physicians have come up against when attempting to diagnose dry eye effectively and accurately in a clinic setting. They also report on the latest research that has yielded some effective and user-friendly instruments, which now make osmolarity testing, and therefore, dry eye diagnosis, much easier.
Adding artificial tear to regimen may boost effectiveness of cyclosporine A
July 15th 2008Cyclosporine A ophthalmic emulsion 0.05% (Restasis, Allergan) is effective in treating moderate to severe dry eye in 70% to 75% of patients with the condition, and adding a specific artificial tear (Systane, Alcon Laboratories) to the treatment regimen may prove beneficial for many other patients.
Eyelid cleanser can reduce bacterial colonization
July 15th 2008An antimicrobial eyelid cleanser (SteriLid, Advanced Vision Research) reduces bacterial colonization in dry eye and blepharitis. The cleanser's active ingredient is linalool, a naturally occurring oil effective against a number of organisms.
New artificial tear benefits patients with dry eye
July 15th 2008A product containing carboxymethylcellulose, glycerin, and a preservative (Optive, Allergan), is a valuable option in the management of dry eye disease according to an open-label study evaluating patients who previously used an artificial tear product.
Topical cyclosporine helps prevent dry eye progression
July 15th 2008Topical cyclosporine 0.05% (Restasis, Allergan) limited progression or improved dry eye severity levels in most patients, while the use of artificial tears alone led to worsening of disease severity levels in nearly one-third of patients in a 12-month randomized study. The rapid progression of the disease in patients using artificial tears and the improvements in the patients using cyclosporine suggest that medication use could be beneficial for many individuals with level 2 dry eye disease.
