Retina

- Lacrimal and lids
- See Lacrimal Anatomy
- Lids
- See Lid Anatomy
- Miscellaneous
- General
-
Eyelids
- Both lids contain a tarsal plate with Meibomian glands
- Lids join at medial and lateral canthi
-
Sclera
- See Sclera
- Thick, protective outer coat of the eye underlying the Conjunctiva
- Normally white (with possible bluish discoloration) and opaque
- Scleral inflammation is very painful, and associated with Vision Loss
- Episclera
- Limbus
- Iris
- Uvea
- Pupil
- Lens
- Fine, variable focus of light directed at the Retina
- Cataracts clous the lens, resulting in Decreased Visual Acuity
- Conjunctiva: Thin, vascular tissue
- Covers inner lid lining (palpebral Conjunctiva)
- Covers Sclera (bulbar Conjunctiva)
-
Cornea
- See Refractive Error
- See Cornea
- Transparent front refractive window of eye
- Macula and Fovea
- See Extraocular Movement
- Medial Range of Motion
- Medial Rectus (Cranial Nerve III)
- Lateral Range of Motion
- Lateral Rectus (Cranial Nerve VI)
- Upward Range of Motion
- Superior Rectus (Cranial Nerve III)
- Inferior Oblique (Cranial Nerve III)
- Downward Range of Motion
- Inferior Rectus (Cranial Nerve III)
- Superior Oblique (Cranial Nerve IV)
- Chambers
- Anterior Chamber
- Between Cornea and iris
- Contains Aqueous Humor
- Posterior Chamber
- Between iris and lens zonulae (very small space)
- Also contains Aqueous Humor
- Ciliary body
- Produces Aqueous Humor
- Contains ciliary Muscle ring
- Suspends lens by fine ligamentous zonule fibers (zonulae)
- Ciliary Muscle Contraction narrows ring diameter, relaxing tension on lens
- Lens assumes and thicker, rounder shape, resulting in Visual Accommodation (near focus)
- Contrast with iris dilator (Mydriasis) and iris constrictor (Miosis) Muscles
- Aqueous Humor
- Aqueous Humor
- Clear fluid that fills anterior and posterior chamber
- Produced by ciliary body
- Passes through pupil
- Drains via trabecular meshwork (at outflow angle)
- Aqueous Outflow Angle
- Aqueous Humor
- Vitreous Cavity
- Large space (4.5 cc) between lens and Retina
- Contains transparent thick gel (vitreous humor)
- Additional vitreous humor is not produced after the eye develops
- Contrast with Aqueous Humor that is produced throughout the eye's lifetime
- Vascular
