Physical changes, altered signaling lead to TM failure
The trabecular meshwork fails in glaucoma because of physical changes in the TM and altered signaling pathways. Abbot F. Clark, PhD, explained the mechanism by which the damage occurs during Glaucoma Subspecialty Day at the annual meeting of the American Academy of Ophthalmology.
Tests may foretell age-related macular degeneration risk
Genotyping of patients to determine the risk of progression to advanced age-related macular degeneration is going to be a critical part of current/ongoing clinical trials and those in the future.
Uveitic glaucoma a challenge
Uveitic glaucoma in children is a common complication of anterior uveitis that often coexists with cataract and band keratopathy.
At issue: Financial, ethical concerns
The advent of femtosecond laser technology for cataract surgery has resulted in myriad issues for ophthalmologists to face: the actual benefits of the laser versus the cost to patients, establishment of the patient share of the costs, associated financial risks for the practice and ambulatory surgery center, advertising, and patient satisfaction.
FDA issues approval of aflibercept for treatment of patients with neovascular AMD, surprise
For the retina subspecialty, the past year was one of controversy, technologic advances, and an important approval from the FDA, as well as a surprise decision from the agency.
Ketorolac formulation eases post-PRK symptoms
Patient comfort seems to increase rapidly after PRK with administration of ketorolac tromethamine 0.45% (Acuvail, Allergan) compared with an artificial tear formulation (Systane, Alcon Laboratories). In addition, the time to re-epithelialization did not differ between the two products.
Laser, crosslinking at forefront of 2011
This year was one in which the femtosecond laser and its applications in refractive and cataract surgery and variations in the applications of crosslinking really began to blossom.
Aflibercept approved for wet age-related macular degeneration
The FDA has approved aflibercept for the treatment of neovascular age-related macular degeneration.
Algorithm addresses corneal scarring
An algorithm for addressing corneal scarring might avoid the need for most corneal transplantation procedures by using the law of optics for optimally shaping the front surface of the cornea. Arun Gulani, MD, MS, uses refractive PRK to treat corneal scars and explained how his system works.
Thin-flap LASIK, PRK provide excellent visual outcomes
A head-to-head comparison study indicated that thin-flap LASIK and PRK both provide excellent visual outcomes to patients with low to moderate myopia. Thin-flap LASIK facilitates more rapid visual recovery than PRK as well as a biomechanically stable cornea compared with conventional LASIK.
