	Aniridia Network - Fovea/Macula Hypoplasia
		The macula is a small area on the retina designed for seeing detail, therefore is the area responsable for visual acuity (20/20 etc. vision).
		In the middle of the macula is the foveal pit, this is a dip in the retina which is made up entirely of densely packed cone cells and no blood vessels run through this area.
		Hypoplasia is a medical term for underdevelopment therefore fovea/macula hypoplasia means underdevelopment of the macula generally or the fovea specificly, there is no clear distinction between the two doctors have their own preference of which term to use.

	The Macula
		The macula lutea is the small, yellowish central portion of the retina, and it is the area providing the clearest, most distinct vision.
		The very center of the macula is called the fovea centralis, an area where all of the photoreceptors are cones; there are no rods in the fovea.
		Cystoid macular edema (CME) is a painless disorder affecting the macula.

	Encyclopedia - Macula
		The densely packed photoreceptor (light-sensitive) cells in the macula control all of the eye's central vision and are responsible for the ability to read, drive a car, watch television, see faces, and distinguish detail.
		Because the macula contains a high concentration of cones, straight-ahead vision is in sharp focus, particularly in bright light.
		The "dry" form is usually the result of aging and thinning of the macula's layers, and the "wet" form occurs when abnormal blood vessels under the retina leak fluid and blood, causing scarring.

	Macula Degeneration
		Macula degeneration is a condition where the central part of the retina becomes damaged.

	Macula - Wikipedia, the free encyclopedia
		The macula or macula lutea (from Latin macula, "spot" + lutea, "yellow") is an oval yellow spot near the center of the retina of the human eye.

		This opacity does not come from the macula but from the optic nerve, which is an area that is normally blind.
		In order to determine positively whether or not the vitreous is still attached to the macula, the doctors at the SRA Foundation have an expert in the field use an exceptionally strong slit lamp with a special lens placed in front of the cornea (Figure 18).
