Composed of:

  • outer pigmented layer - this layer is in contact with the choroid
  • inner sensory layer - this layer is in contact with the vitreous
  • macula - located at the centre of the posterior part of the retina; appears slightly oval and yellowish
  • fovea - this is term used to describe the centre of the macula; this area of the retina has many cones; visual acuity is greatest here
  • the optic disc is medial to the fovea (about 3 mm); the optic disc is the visual field's blind spot and contains no rods or cones
