Understanding circadian patterns, drug efficacy could improve care
Knowledge about the circadian pattern of IOP and the 24-hour efficacy of glaucoma medications is increasing, which is expected to improve medical management of glaucoma in the future.
Study: CXL for corneal ectasia requires oxygen within tissue
CXL protocols using high irradiance/short irradiation time or leaving the epithelium on may limit the opportunity for adequate oxygen replenishment within the cornea, resulting in unsatisfactory outcomes.
Study identifies flap striae risk influenced by climatic conditions
A retrospective study including more than 614,000 eyes undergoing femto-LASIK at a single practice over a 5-year period identified a flap striae incidence of 0.85% overall, however a climate conditions influence was also noted.
Study: Endophthalmitis low despite antibiotic-free intravitreal injection
Analyses of safety data from Diabetic Retinopathy Clinical Research Network (DRCR.net) trials show a very low rate of endophthalmitis can be achieved in eyes receiving intravitreal drug injections using protocol that does not use topical antibiotics, said Abdhish R. Bhavsar, MD.
New guidelines to manage hypertension use evidence-based methodology
Hypertension is the most common disease seen among adults in a primary care practice, and is a leading preventable cause for other serious morbidity and mortality. Here are the new guidelines that physicians need to know.
Androgen deprivation therapy overuse still problematic among some urologists
Inappropriate use of a gonadotropin-releasing hormone agonist for androgen deprivation therapy of localized prostate cancer fell dramatically following implementation of reimbursement cuts mandated by the Medicare Modernization Act of 2003, but overuse remains problematic, according to research presented at the American Society of Clinical Oncology annual meeting in Chicago.
Faster visual recovery next goal for refractive surgery
Although patients undergoing thin-flap LASIK performed with modern femtosecond and excimer lasers can expect excellent vision on the day after surgery, faster visual recovery might enhance the procedure’s appeal, according to Daniel S. Durrie, MD.
Other factors play role in improving diagnosis, management of NTG
IOP is the only proven modifiable risk factor for progression of normal-tension glaucoma (NTG). However, Shan Lin, MD, says there is some compelling evidence that a number of other variables play a role. Dr. Lin reviewed information from studies investigating cerebrospinal fluid (CSF) pressure, myopia, sleep apnea, low blood pressure (BP), oxidant minerals (calcium and iron), and oral contraceptive (OC) use, and found that these factors may contribute to NTG progression.
Smartphone photography to accelerate age of telemedicine
Physicians are taking pictures of eye problems with their personal smartphone, and smartphones are expected to have a tremendous impact in expanding telemedicine, reports Robert T. Chang, MD. However, while smartphone cameras may function well for pictures of the external eye, they lack the proper magnification and lighting to provide the necessary detail when capturing intraocular images. New adapters are addressing those limitations to enable smartphone fundus photography and acquisition of other high quality anterior segment images.
Self-tonometry, new monitoring systems provide wealth of data
The availability of technologies for ambulatory IOP measurement will usher in a new era in glaucoma patient management. L. Jay Katz, MD, said the technologies will provide better understanding of IOP and patient adherence to topical medications and to make more timely adjustments in therapy while reducing the number of office visits.
