Primary Eye & Vision Care Lecture Notes

These flashcards cover key vocabulary terms and definitions related to primary eye care and ocular anatomy.

Primary Eye Care

A frontline activity providing eye care and identifying disease before it becomes serious.

World Health Organization (WHO)

Declared primary health care to be essential for achieving health for all in 1978.

Integrated Primary Eye Care (IPEC)

Services managed to provide a continuum of health interventions covering promotion, prevention, treatment, and rehabilitation.

Extraocular Muscles

Muscles responsible for the movement of the eye.

Rectus Muscles

Straight muscles that include Medial Rectus, Lateral Rectus, Superior Rectus, and Inferior Rectus.

Refractive Media

Components of the eye that include Cornea, Aqueous Humor, Crystalline Lens, and Vitreous Humor.

Levator Palpebrae Superioris (LPS)

A muscle in the orbit that lifts the upper eyelid.

Sclera

The white part of the eye that gives the eyeball its shape.

Palpebral Conjunctiva

Membrane that helps protect the eye from infection and covers the inside of the eyelids.

Bulbar Conjunctiva

A clear and smooth part of the eye allowing a view of the sclera.

Cornea

Clear, glass-like structure that focuses light into the eye.

Pupil

The black hole in the center of the iris that controls the light entering the eye.

Crystalline Lens

Transparent structure that changes shape to focus light on the retina.

Emmetropia

The condition of having no refractive errors with light focusing correctly on the retina.

Ametropia

An optical error that can be corrected by vision aids like glasses or contact lenses.

Myopia

Refractive error where light rays focus in front of the retina, corrected with minus lenses.

Hyperopia

Refractive error where light rays focus behind the retina, corrected with plus lenses.

Astigmatism

An optical condition caused by an irregular shape of the cornea or lens.
