Zeiss announces launch of Humphrey Field Analyzer 3

CORONADO, Calif. — Carl Zeiss Meditec announced the global launch of the Humphrey Field Analyzer 3, a new iteration of its established perimetry platform, at the American Glaucoma Society meeting here.According to a company press release, the HFA3 features patented liquid lens technology, which is designed to save time and improve efficiency.

NASA looks at visual impairment intracranial pressure risk in astronauts

CORONADO, Calif. — NASA is looking at causes of ocular changes in U.S. astronauts before, during and after 6-month space flights on board the International Space Station.Ocular findings have developed in 22 of 31 astronauts so far, either during or after a 6-month flight, Christian Otto, MD, said at the annual meeting of the American Glaucoma Society. Those findings include hyperopic shift, choroidal folds, optic nerve sheath distention, optic nerve kinking, globe flattening, disc edema and cotton wool spots. In five of six subjects who underwent post-flight lumbar puncture, cerebrospinal (Read more...)

Progressive retinal nerve fiber layer loss associated with quality of life measure changes

CORONADO, Calif. — Progressive retinal nerve fiber layer thickness loss was associated with loss of quality of life in glaucoma patients, even after adjustment for degree of visual field loss as measured by standard perimetry, a speaker said.“These findings suggest that rates of structural change assessed by OCT imaging may be valid markers for the degree of self-reported disability associated with glaucoma,” Carolina P. Gracitelli, MD, said at the annual meeting of the American Glaucoma Society.

VIDEO: Small pupil issues in femtosecond laser cataract surgery

ISTANBUL – At the ESCRS Winter Meeting, Boris Malyugin, MD, PhD, talks about small pupil issues in femtosecond laser cataract surgery. Laser shots applied to the capsule and nucleus generate prostaglandins in the aqueous humor, leading to pupil contraction. While in most cases this complication can be avoided with a proper medication protocol, 12-30% of patients might be refractory to treatment and require application of mechanical expansion devices.

Fluorometholone treatment faster than cyclosporine A for Sjögren’s syndrome ocular dryness

Successful treatment of ocular dryness with fluorometholone occurred faster than treatment with cyclosporine A in patients with Sjögren’s syndrome, according to a recent report.Between January 2013 and September 2013, researchers selected 40 patients with primary or secondary Sjögren’s syndrome (SS) from the Eye, Ear, Nose and Throat Hospital of Fudan University in Shanghai, China, for inclusion in a randomized, open, parallel-group study. Patients included in the study had non-anesthetized Schirmer test results of 5 mm per minute or less, a 1% corneal fluorescein staining (CFS) score of three or greater (Read more...)

Early studies examine neuroregeneration in optic neuropathies

CORONADO, Calif. — Whether called neuroprotection, neuroenhancement or regeneration, any of these would be a major step forward in restoring vision in optic neuropathies, a speaker told colleagues.“Glaucoma and other optic neuropathies, at the end of the day, are going to share more similarities as we figure out how to treat them at the level of the optic nerve head,” Jeffrey L. Goldberg, MD, PhD, said at the annual meeting of the American Glaucoma Society. “The fundamental problem underlying all of these optic neuropathies, including glaucoma, is that, just like (Read more...)

Optometrists weigh in on TheDress

On Thursday, a photo of a dress was posted to the blogging site Tumblr and went viral.In the original post, the author said that she and her friends were debating over the color of the dress – some of them saw it as blue and black and some of them saw it as white and gold.

Nikon moves into ophthalmology with purchase of Optos for $400 million

The board of directors of Nikon and Optos have agreed the terms of a recommended cash offer of £259.3 million ($400 million) for the acquisition of Optos, according to an announcement from Nikon.The proposed acquisition of Optos is an important step in Nikon’s initiative to enter the medical sector to leverage its optical technologies into the medical industry, the announcement said.

Patient management individualized by presentation in normal tension glaucoma

CORONADO, Calif. — Work-up in patients with normal tension glaucoma should be individualized according to their presentation, particularly when they are suspected of belonging to certain common subsets with non-IOP-dependent components of the disease, according to a speaker.“If you think that all normal tension glaucoma is the same and you only have one tool to treat it, I don’t think you’re doing the best for your patients,” Martin B. Wax, MD, said at the annual meeting of the American Glaucoma Society in a joint symposium with the North American Neuro-Ophthalmology (Read more...)

Prevalence of normal tension glaucoma varies with ethnicity

CORONADO, Calif. — Epidemiologic studies have shown that the prevalence of normal tension glaucoma varies considerably depending on ethnicity, with the highest prevalence found in Asian populations, according to Janey Wiggs, MD, PhD.Among 24 studies that looked at prevalence of normal tension glaucoma in various countries, one study from Japan reported a 92% rate in that population, whereas an Ethiopian study reported a less than 10% rate, according to Wiggs’ presentation at the American Glaucoma Society annual meeting. Whether the increased prevalence in Asian populations is due to genetics or (Read more...)

VIDEO: Evolution of femtosecond laser cataract surgery

ISTANBUL – At the ESCRS Winter Meeting, Zoltan Nagy, MD, talks about femtosecond laser cataract surgery, which he pioneered with the first worldwide performance in 2008. Since then the technique has rapidly evolved and is currently used also in complicated cataract cases and pediatric cataract, with excellent results. The future, according to Nagy, are coupled systems for lens and corneal surgery, glaucoma surgery and possibly retinal surgery.

CMS completes first week of ICD-10 end-to-end testing

The CMS concluded its first successful end-to-end testing week of the new ICD-10 coding, the agency announced in a blog post. “Testing allows us to identify areas of improvement, and we will work with outside entities and stakeholders to improve those very small deficiencies identified,” Marilyn B. Tavenner, administrator for the CMS, said in the post. “And we will continue to do testing, especially in those areas we identify as needing improvement.”

Turkish study investigates effects of heavy smoking on corneal biomechanics

ISTANBUL — A study comparing corneal biomechanics of heavy smokers and nonsmokers in Turkey found no significant difference, but there was a tendency for increased stiffness in the corneas of heavy smokers, particularly those over the age of 40 years.Turkey is among the top 10 countries for tobacco consumption in the world, Ayşe Ebru Kilavuzoglu, MD, said at the winter meeting of the European Society of Cataract and Refractive Surgeons.
