OCT useful for detecting vitreofoveal traction, thickness
April 15th 2003Royal Oak, MI-Optical coherence tomography (OCT) may be more sensitive than fluorescein angiography in detecting vitreofoveal traction and differences in thickness in the different areas of the macula in patients with persistent diabetic macular edema (DME). While fluorescein angiography remains the standard in imaging, Cynthia Carvalho-Recchia, MD, suggested an adjunctive role for OCT in patients with DME.

Povidone-iodine considered best endophthalmitis prophylaxis
April 15th 2003Indianapolis-Preoperative povidone-iodine antisepsis showed the strongest support in the literature for preventing bacterial endophthalmitis in patients undergoing cataract surgery. However, that recommendation was judged to be only "moderately important" to clinical outcome, based on the quality of the available evidence. The review failed to find that any technique was crucial to clinical outcome, said Thomas A. Ciulla, MD.
Automated anterior lamellar keratoplasty offers advantages
April 15th 2003Forli, Italy-Automated anterior lamellar keratoplasty offers a number of advantages over other therapeutic approaches in the treatment of keratoconus, according to Massimo Busin, MD.

April 15th 2003Little Silver, NJ-LASIK monovision is a viable choice for both myopia and hyperopia, but careful patient selection is crucial for best results, particularly among patients with hyperopia, said Daniel B. Goldberg, MD, FACS, Atlantic Laser Center, Little Silver, NJ.
Re-treatment after LASIK is no trivial matter
April 15th 2003Baltimore-Use caution when re-treating a patient who has had refractive surgery, advised Nada S. Jabbur, MD. Just as care should be taken in performing initial LASIK procedures, re-treatments require special care and should not be trivialized, according to Dr. Jabbur.

April 15th 2003Orlando-Children with moderate amblyopia may be successfully treated with patching or atropine drops, regardless of age less than 7 years or depth of amblyopia for the most common causes of amblyopia, according to Michael X. Repka, MD, at the American Academy of Ophthalmology annual meeting.
B&L wins extended range on laser; delays implant application
