Macula

Central part of the retina. Composed uniquely of cone cells and enables precise vision.

Macula, macula lutea

The central portion of the retina that is responsible for central vision. An insult to the macula can cause loss of central vision and a significant decrease in visual acuity.

Macular oedema

The accumulation of fluid within the central area of the retina. This may occur as a complication of intraocular surgery, as a response to uveitis or as a complication of other retinal conditions such as diabetic retinopathy.
