Evidence suggests that nitric oxide can modify both mechanical and vascular events in primary open-angle glaucoma pathogenesis.

OCT angiography (AngioPlex OCT Angiography) is now available as an upgrade to the CIRRUS 5000 HD-OCT platform (Carl Zeiss Meditec). The technology allows visualization of the blood flow and microvasculature in the retina, choriocapillaris, and choroid with the ease of noninvasive imaging.

A knowledgeable optician is obviously an asset to an ophthalmology practice that is wanting to make computer lenses available to a greater number of its appropriate patients.

Ophthalmologists discuss the importance of routine contrast sensitivity and glare testing in cataract-age adults and specifically the use of a platform that includes a real-world driver’s scene.

In order to test the authors intriguing hypothesis that topical beta blockers improve acute migraine we will need a well-designed, statistically valid, large sample size, randomized, double masked, placebo controlled, clinical trial that would have defined primary outcome measures as well as strict inclusion and exclusion criteria.

Ultra-widefield (UWF) imaging provides clinicians a much broader view of the retinal periphery. The Optos California uses multiple UWF imaging modalities, including color, autofluorescence, fluorescein angiography (FA), and indocyanine green (ICG) angiography in a 200° picture.

No physician has the ultimate knowledge and should not be afraid to engage colleagues in the treatment of a patient. Usually, the patient will appreciate the concern and will continue as a patient.

The DOCK, of course, is the Demonstration of Ophthalmic Cognitive Knowledge, the final step for me in completing my second round of Maintenance of Certification requirements for the American Board of Ophthalmology (ABO). Taking this exam initiated a period of contemplation regarding where I’ve been and where I’m going.

Switching from ranibizumab to aflibercept may allow some patients to extend the time between treatments for neovascular age-related macular degeneration (AMD), researchers say.

Professor Steve Arshinoff and Rayner CEO Tim Clover announce Rayner's recent acquisition of the Ophteis OVD range at the Company's celebratory event, held at the 2015 ESCRS in Barcelona.

There are essential components to a budget for your practice-rent, utilities, and staff wages to name a few. But there should also be another section in your budget for marketing.

Vitreomacular traction resolved in one-third of patients treated with ocriplasmin (Jetrea, ThromboGenics) within 28 days in a phase IV study of the new medication, according to Dr David Steel.

Microsurgical instruments enable surgeons to perform complicated anterior segment eye procedures through good control of tissue handling. In this article, Dr Little explains how fine-gauge instruments allow for procedures such as iris reconstruction to be performed far more easily than was previously possible.

Narrow angles have been associated with a higher IOP in glaucoma patients, presumably by causing higher outflow resistance. Here, Dr Loewen presents recent research in which both ab interno trabeculectomy (AIT) with the trabectome and phaco-AIT significantly reduced IOP and number of medications required, regardless of the degree of angle opening.

The evaluation of multiple optical coherence tomography images supports the combined tractional-hydration theory of idiopathic macular hole formation, progression, and closure.

A community-based teleophthalmology program providing diabetic retinopathy screening is helping to improve the eye health of the Latino population in Milwaukee.

CO2 laser-assisted sclerectomy surgery performed with a proprietary platform is a simple and safer alternative to manual non-penetrating deep sclerectomy for eyes with open-angle glaucoma.

Functional vision loss in children is a relatively common problem. Although physicians may be hesitant to delve into conversations with children and parents when there is no evidence of organic disease, it is better to probe for cause of stress, anxiety, or depression stemming from issues with family, school, outside activities, or friends, and to identify for the patient and parents areas for attention that may be previously unknown or overlooked.

A pinhole implant placed in the ciliary sulcus can improve visual acuity and reduce dysphotic symptoms in pseudophakic eyes with irregular corneal astigmatism. Implantation is even easier with the latest version of the investigational device

The AREDS2 findings have empowered ophthalmologists to recommend appropriate supplements to reduce risk of visual loss in patients with AMD. In this article, the authors discuss the emerging revelation that the constituents of macular pigment enhance visual performance and explain how supplementation with all three macular carotenoids in a MZ:L:Z (mg) ratio of 10:10:2 can confer the greatest benefits.

Most patients with acute nonarteritic central retinal artery occlusion have a cardiovascular risk profile, and a comprehensive medical evaluation can uncover more risk factors.

The neuroprotective effects of intraocular treatment with erythropoietin in the reduction of geographic atrophy progression and vision loss were reviewed in an off-label study.

In pediatric cataract surgery, use of an ocular sealant not only also helps prevent wound leakage but also provides extra protection against eye rubbing and wound manipulation.

A pilot study suggests that using subthreshold photostimulation with a 577-nm PASCAL yellow laser is an effective and safe option for central serous chorioretinopathy.

Long-term cone functional rescue was achieved in dogs with achromatopsia AAV vectors containing codon-optimized human CNGB3 and an improved promoter, which may be a stepping stone to treating achromatopsia in humans.

Prof. Fujikado presents his research, which demonstrated the surgical feasibility and safety of a newly developed, dual-array, suprachoroidal-transretinal stimulation prosthesis in animals. The dual-array design was able to activate retinal neurons and optic nerve axons. Findings indicate the future possibility of activating of a larger visual field with the prosthesis.

Some medical specialties are exploring the possibility of abolishing recertification examinations every 10 years in favor of other alternatives. Is ophthalmology next?

Rules can serve as invaluable guidelines for the future, as they are lessons learned from experience.

In this third of a four-part column, Arun C. Gulani, MD, continues the discussion on staged cataract surgery.
