Anatomy of the Conjunctiva, Limbus, Anterior Chamber, and Angle

Limbus through the fornices into the eyelids. Palpebral conjunctiva: lines the eyelidsBulbar conjunctiva: lines the eyeballFoniceal conjunctiva: lines the fornices.

1. Stratified epithelial layer: continuous with the corneal epithelium. Superficial cells have microvilli and goblet cells and their cytoplasm contains melanin granules2. Submucosa: CT stromal layer, like the corneal stroma.

Conjunctival fold at the medial canthus that contains smooth muscle, goblet cells and adipose tissue to reduce stretching of conjunctiva on lateral eye movements. Provides slack in the conj. for lateral movement.

Hill of tisssue located on the medial side of the plica semilunaris. unknown function. Contains goblet cells, hair follicles, and sebaceous and sweat glands. Likely source for the collection of debris and gunk that is present when you wake up in the morning.

Palpebral and forniceal portions are supplied by the peripheral arcades. The bulbar conj is supplied by the anterior ciliary arteries.

Bulbar conjunctiva: Innervated by the long posterior ciliary nervesPalpebral conjunctiva: V1 and V2

Between the iris and the vitreous

The lens capsule, the lens epithelium, and the lens fibers. Lens capsule is outermost, lens fibers = bulk of the interior of the lens

Directly under the lens capsule

Just in front of the posterior capsule. PSC's often affect near vision more than distance vision and are commonly a result of systemic steroid use.

systemic steroid use.

Nuclear: commonly introduce myopic shifts.

Anterior, equatorial and posterior cortex layers. The present as spoke-like projections

At the anterior midperipheral portion of the lens.

At the posterior pole.
