Optic Nerve Head Drusen
Drusen in the retina is a common finding in aging retina, forming deposits in the retina between Bruch’s membrane and the retinal pigment epithelium. Most people over 40 start to accumulate some drusen, but increasing amounts of drusen formation can indicate pathological developments associated with age related macular degeneration, (AMD). Cristine Curcio has been chasing …
Acute Zonal Occult Outer Reinopathy (AZOOR)
This photo shows peripheral vasculitis in a patient with Acute Zonal Occult Outer Retinopathy (AZOOR). Five images were taken in each eye and composited together to show the peripheral changes taking place in the mid arterivenous phase of the fluorescein angiogram. This image was made by James Gilman of the Moran Eye Center using a 102 degree non-contact …

Wavelengths Of Light From Our Sun
The National Optical Astronomy Observatory has assembled a high resolution image showing the spectrum of our Sun from 296 to 1300nm. Its interesting to note that visual systems on planet Earth have evolved to detect wavelengths of light given off by our sun and those wavelengths are solar specific. Other stars radiate different wavelengths, but I’d …

Choroidal Neoplasm
Choroidal neoplasms are tumors of the choroid of the eye. The most common intraocular tumors are in fact, malignant melanomas of the choroid which increase in frequency as we age. This case study came from a 66 year old white male who presented to the Moran Eye Center with a dark brown pigmented iris lesion …
Vision Scientists and Artists, Helga Kolb
It turns out that quite a number of vision scientists are artists and photographers and what they “see” is often a reflection of how they think about vision and the science behind vision. They often seen the world just a little differently and taking the time to explore it is often rewarding. Its only appropriate …

Notable Paper: Tuning The Electronic Absorption Of Protein-Embedded All-Trans-Retinal
The pigments in retinal photoreceptor cells absorb varying wavelengths of light, but the central chromophore, the molecule that actually absorbs the photon is identical. Its ability to tune the responsiveness comes from the association with other opsins giving an organism the ability to respond from the near ultraviolet all the way to far red. Interestingly, …
