Smartphone ophthalmoscopy images may nearly equal the quality and diagnostic utility of traditional fundus camera images, according to a study.

OCT uses a relatively long wavelength near infrared light to create a three-dimensional high-resolution cross-sectional image of tissue. The light collected to create the images is reflected or backscattered from the tissue. OCT can image both transparent and opaque tissue and routinely penetrate 500 µm to as much as 1,000 µm into tissue. A typical OCT device used in an ophthalmology practice today has a resolution in the 10-µm range. Thus, a single cell such as a retinal ganglion cell, photoreceptor, retinal pigment epithelial cell or corneal epithelial/keratocyte/endothelial cell can be imaged.

A specified ophthalmic screening protocol accurately detected eye disease in an American Indian and Alaskan Native population. However, the protocol needs to be tested in diverse populations with varying disease profiles, a study found.

Smartphone ophthalmoscopy images may nearly equal the quality and diagnostic utility of traditional fundus camera images, according to a study.

VIENNA — At the American Society of Retina Specialists meeting here, Kakarla V. Chalam, MD, PhD, MBA, discusses his presentation on angio-optical coherence tomography, a new technique that he believes is revolutionizing the diagnosis and management of retinal diseases.

NASA is banding together with thought leaders in ophthalmology and industry to try to remedy vision problems encountered by astronauts in space for lengthy periods of time. The hope is that in-flight monitoring and treatments will counter the detrimental effects of living in essentially a gravity-free environment.

Space is a hostile environment for the human body. We are all aware of the great risks taken in being rocketed into space and returning to Earth, with several memorable tragic accidents. Once in space and safely into the International Space Station, there remain many physiologic challenges that impact nearly every part of the body.

DENVER — A teleophthalmology program using ultra-widefield imaging may assist standardized grading at reading centers for diabetic retinopathy evaluation, according to a presentation here.

Despite rapid advances in portable video technology, it remains difficult to record what we see down the slit lamp or through the operating microscope. A further challenge is to then process any recorded material into a format useful for learning and sharing. This month, I interviewed Maninder Bhogal, FRCOphth, who shares his story of developing the EyeCamHD from scratch and gives his advice to young ophthalmologists with their own innovative ideas.

Next-generation DNA sequencing demonstrated the capability to alter clinical management, direct care pathways and enable accurate genetic counseling in the diagnosis of bilateral congenital cataract, according to a study.
