Monochromatic ophthalmoscopy and fundus photography. The normal fundus. 1977

Anatomical details in the ocular fundus can be seen with increased contrast when appropriate monochromatic illumination is used. This technique permits more accurate visualization and documentation than can be achieved with white light. This article reports the optimal spectral ranges for visualization of the different fundus structures. It describes and illustrates the appearance of individual structures and areas of the fundus under different spectral illuminations. There is a detailed discussion of the optical properties of the fundus layers that provides a background for interpreting the data and a baseline for examination of pathologic conditions.

UI MeSH Term Description Entries
D008266 Macula Lutea An oval area in the retina, 3 to 5 mm in diameter, usually located temporal to the posterior pole of the eye and slightly below the level of the optic disk. It is characterized by the presence of a yellow pigment diffusely permeating the inner layers, contains the fovea centralis in its center, and provides the best phototropic visual acuity. It is devoid of retinal blood vessels, except in its periphery, and receives nourishment from the choriocapillaris of the choroid.
