Iris tumors are fairly common and have been featured here on Webvision before. Most “tumors” are actually cysts or benign nevi, but malignant melanomas also can occur. Continue reading “Iris Tumor Goniometer”
Keratoprosthesis
This image is from a patient has a keratoprosthesis or artificial cornea. Photograph was made by James Gilman of the Moran Eye Center using a sclerotic scatter illumination with a Zeiss photo slitlamp and a Nikon D-1X camera.

Iris Tumor
This image demonstrates an iris tumor that is sitting in the angle. Photograph was made by James Gilman of the Moran Eye Center using a Goldmann 3-mirror lens scatter illumination with a Zeiss photo slitlamp and a Nikon D-1X camera.
Toxic Anterior Segment Syndrome (TASS)

Foveal Avascular Zone
This is normal fluorescein angiogram of a human retina showing the tunic of capillaries that surround the fovea and rather nicely illustrates the Foveal Avascular Zone (FAZ) discussed in The Simple Anatomy of The Retina. Photograph was made by James Gilman of the Moran Eye Center.
Artisan Lens
The artisan lens is an anterior chamber lens used to treat patients with high myopia. Photograph was made by James Gilman of the Moran Eye Center using sclerotic scatter illumination with a Zeiss photo slitlamp and a Nikon D-1X camera.
Ophthalmologic Care In The 1800s
CBS news has a post up with a collection of photographs from the 19th and 20th centuries of ophthalmologic care from the extensive and excellent archives of The Burns Archive, one of the largest collections of early medical photography in the world curated by Dr. Stanley B. Burns. Note: some images are potentially disturbing.
Light-Evoked Synaptic Activity of Retinal Ganglion and Amacrine Cells is Regulated in Developing Mouse Retina
This paper by Q. He, Wang P and Ning Tian characterizes the developmental profiles of the light evoked excitatory and inhibitory synaptic inputs from ON and OFF synaptic pathways in the retina, the light evoked synaptic outputs and the sensitivity of the light evoked synaptic inputs and outputs to light deprivation of retinal ganglion cells (RGCs) and displaced amacrine cells (ACs) of developing mouse retina. The results strongly suggest that spontaneous and light-evoked synaptic activities of RGCs and ACs are regulated by different synaptic mechanisms.
A Photographers Visit to the Moran Eye Center
A friend of Webvision, renaissance man and photographer extraordinaire, Duncan Davidson visited us at the Moran Eye Center and hung out for a day of science while we performed experiments. Duncan documented some of the work we did that day in the lovely video he posted to Vimeo above. You have quite possibly seen Duncan’s work before on CNN or of individuals giving talks at the TED conference as Duncan is the official TED photographer.

Iris Sphere
We present to you for your Friday viewing, another entry in the Art of Vision category, an artistic image of a montage of the iris and pupil from James Gilman of the Moran Eye Center
Stargardt’s Disease angiogram
Venous phase fluorescein sodium angiogram of a dark choroid in Stargardt’s disease or fundus flavimaculatus. Stargart’s Disease is a progressive retinal degenerative disease caused by mutations in one of 3 genes, ABCA4, ELOVL4 or PROM1. The disease is a form of juvenile onset macular degeneration affecting the retinal pigmented epithelium (RPE). The disease onset and progression is usually bilateral.

Moran Eye Center Abstracts 2011
Every year in time for ARVO, the Moran Eye Center puts together a compendium of research abstracts that come out of the research efforts of faculty, post-docs and students here.
