The Special Senses
External Anatomy of the Eye
Lacrimal Apparatus of the Eye
Anatomy of the Eyeball
Accessory structures of the Eye from a sagittal view
Detail view of the anterior anatomy of the eye
Photomicroscopic view of the Histology of the Eyeshowing the
location of the central foveaIntrinsic Eye Muscles and their
response to light
Abnormalities ofThe Eye:Myopic - nearsightedHypermetropic -
FarsightedPresbyopia - age-related failure of lens to
accommodateAstigmatism - Distorted vision due to irregular-shaped
lens orcorneaColor Blindness - genetic defect that causes
dysfunction of conesAccommodation of the Lens for near
visionCiliary muscles contractCiliary body pulls forward and
inwardTension on suspensory ligaments of lens is decreasedLens
becomes thicker (rounder) due to its elasticityPupils
constrictsAccommodation of the Lens for far visionCiliary muscles
relaxesCiliary body returns to its resting state, backward and
outwardTension on suspensory ligaments of lens is increasedLens
becomes thinner (flatter) due to its elasticityPupils dilate
