The retina changes light waves into nerve impulses that are conducted through the optic nerve to the visual cortex.
It assesses the parallel alignment of the eye axes and can indicate muscle weakness or paralysis.
It provides constant irrigation to keep the conjunctiva and cornea moist and lubricated.
It is the area where fibers from the retina converge to form the optic nerve, and its characteristics can indicate various eye conditions.
Pupils Equal, Round, React to Light, and Accommodation.
Tarsal plates are strips of connective tissue in the upper lid that give it shape and contain meibomian glands, which secrete oily lubricating material to prevent tears from overflowing.
They attach the eyeball to its orbit and allow for both straight and rotary movements of the eye.
Cataract formation, which is a clouding of the crystalline lens.
It is the decreased ability of the lens to change shape for near vision, commonly occurring in older adults.
A leading cause of blindness in working-age adults caused by chronic hyperglycemia leading to damage and inflammation of the retina.
Upper eyelid, palpebral fissure, lateral canthus, lower eyelid, pupil, iris, sclera, medial canthus, caruncle, and limbus.
It is the normal constriction of the pupils when bright light shines on the retina, involving the optic nerve (CN II) and the oculomotor nerve (CN III).
Vision difficulty, pain, strabismus, redness, swelling, watering, discharge, history of ocular problems, and use of glasses or contact lenses.
It screens for loss of peripheral vision by comparing the person's peripheral vision with that of the examiner.
An optic nerve compression caused by increased intraocular pressure, leading to gradual vision loss.
They protect the eye from injury, strong light, and dust, acting like rapid window shades.
Loss of skin elasticity, decreased tear production, changes in lens elasticity, and increased risk of cataracts and other eye diseases.
Early detection and correction of vision problems can lead to better school performance and improve physical, cognitive, and social development.
