End-stage age-related macular degeneration investigational IOL developed
November 15th 2008A prismatic IOL (P-Flex, Rayner) is giving hope to patients with advanced age-related macular degeneration because of its novel design. A Fresnel prism in the IOL reflects images onto healthy retinas in patients with small macular lesions. No scotoma or diplopia has resulted from implantation of this IOL in two patients.
Age-related macular degeneration and diabetic retinopathy phase III trials show promise
November 15th 2008Drug development for retinal disease is particularly challenging because traditional routes of drug delivery often are unable to achieve desired therapeutic levels, and the disease process often involves multiple complex pathways. An unmet medical need still exists-particularly for the two most prevalent diseases, age-related macular degeneration and diabetic retinopathy-but several phase III trials show promise.
Symmetrical versus asymmetrical globe placement: It's no fluke
November 15th 2008One concern of the theory of evolution is how a highly complex organ such as the eye might develop if there are not intermediate forms of rudimentary eyes that confer a survival advantage to the organism. An intermediate life form recently has been discovered, and Ophthalmology Times Chief Medical Editor Dr. McDonnell hypothesizes that it may have implications for patient care.

When amblyopia treatment fails, adherence is likely an issue
November 15th 2008Parents of children with amblyopia may have several reasons (or excuses) for not following a prescribed patching regimen. Ophthalmologists who are following the Pediatric Eye Disease Investigator Group guidelines but are not achieving the desired results, should first examine whether patients are adhering to the prescribed therapy.
Managing posterior uveitis in children a must
November 15th 2008The adequate management of posterior uveitis in children is difficult but imperative. Many treatment options exist, but to determine the best one for patients, it may be best to divide them into two groups at least initially: those with unilateral disease and those with bilateral disease. Treatment decisions then will follow, based on the severity of the disease.
AAO updates media on key ophthalmic issues
November 10th 2008In the past year, the world of ophthalmology has seen some significant headlines.

Ophthalmologists gain insight to Charles Bonnet Syndrome hallucinations
November 10th 2008Visual hallucinations caused by Charles Bonnet Syndrome (CBS) are not infrequent in older individuals with decreased visual function. While individuals who experience these hallucinations, which are usually generic people, animals, patterns, or scenes, understand that what they are seeing is not real and often are not disturbed by the images, they are worried about the reaction of their families, friends, and physicians.
Secondary piggyback IOL successful option
November 10th 2008When faced with a postcataract surgery refractive surprise, implanting a secondary piggyback IOL can be a successful option with careful attention to selecting appropriate candidates, IOL model, and power calculation technique, said Warren E. Hill, MD, a private practitioner, Mesa, AZ.
Simple measures improve cataract surgery outcomes for postLASIK eyes
November 10th 2008The difficulty of accurate IOL power calculation in postLASIK eyes is an issue being faced increasingly by cataract surgeons. Jack T. Holladay, MD, clinical professor of ophthalmology, Baylor College of Medicine, Houston, offered several tips for achieving better refractive outcomes in this growing population of eyes.
Pars plana approach preferred for anterior vitrectomy
November 10th 2008If the posterior capsule breaks during cataract surgery and vitreous presents to the anterior chamber, patients are best served by anterior vitrectomy using a pars plana technique, said Louis "Skip" Nichamin, MD, medical director, Laurel Eye Clinic, Brookville, PA.
Cataract surgery: Benefits on IOP more significant than realized
November 10th 2008Instead of combined surgery, cataract extraction alone by phacoemulsification through a clear corneal incision with posterior chamber IOL implantation may be the most appropriate procedure for patients with controlled or modestly uncontrolled glaucoma as well as for patients with ocular hypertension or glaucoma suspects, said Richard L. Lindstrom, MD, in his delivery of the Kelman Lecture during the Spotlight on Cataract Surgery session of the annual meeting of the American Academy of Ophthalmology.
Author De Gennaro signs his new book, 'The Dispensing Ophthalmologist'

The book is written by Arthur De Gennaro, president of Arthur De Gennaro & Associates LLC, Lexington, SC, an ophthalmic practice management firm that specializes in optical dispensary issues.
Tips and techniques for cataract and refractive success: The dry eye connection
November 10th 2008Dry eye disease and cataract and refractive surgery are intertwined closely. Pre-existing dry eye can affect surgical outcomes and, in severe cases, is a contraindication for surgery, whereas surgery causes trauma to the ocular surface and may lead to signs and symptoms of dry eye. To break this cycle, a two-pronged approach of treating dry eye before surgery and taking steps to prevent its development postoperatively is advisable.

November 10th 2008Ptosis is a sign of a number of diseases, most of which are benign. Julie Falardeau, MD, of the Casey Eye Institute, Portland, OR, described how ophthalmologists can avoid overlooking myasthenia gravis, which can be associated with serious morbidity and mortality.
Laser photocoagulation still standard of care for diabetic maculopathy
November 10th 2008The Early Treatment Diabetic Retinopathy Study (EDTRS) laser is still the standard of care of diabetic maculopathy. There is enthusiastic support for the potential of pharmaceutical therapy, using anti-vascular endothelial growth factor agents, however, the laser remains the gold standard, said Francesco Bandello, MD, of the University of Udine, Udine, Italy.
Distinct patterns of diabetic maculopathy seen on OCT
November 10th 2008Optical coherence tomography (OCT) is valuable in managing diabetic macular edema (DME), more so than fluorescein angiography, in which the degree of leakage is not correlated with visual acuity and outcomes, according to Peter Kaiser, MD. In addition, angiography does not show vitreoretinal abnormalities that may require a different treatment.
