Cornea - detail (HE)[edit | edit source]
Description: 1 – anterior epithelium (multi-layered squamous non-keratinizing epithelium – 6 layers), 2 – membrana limitans anterior Bowmani, 3 – substantia propria represents 90% of the thickness of the cornea (it is formed by collagen fibrils), proteoglycans, water and fibroblasts-keratocytes), V – air.
Corneal Conjunctival Transition (HE)[edit | edit source]
Description: ES – conjunctival epithelium (multilayered cylindrical) is a continuation of the pER corneal epithelium, SR – corneal stroma is a thin tissue containing immune cells, mast cells and numerous blood vessels that form a blood network around the limbus, c – vessel, pER – anterior epithelium of the cornea (multilayer squamous epithelium non-keratinizing – 6 layers), bm – Bowman's membrane, SP – substantia propria of the cornea, dm – Descemet's membrane, zER – posterior epithelium of the cornea (single-layered epithelium flat), V – air, CA – camera anterior (front eye chamber), KT – chamber fluid, arrow – transition of the cornea in the conjunctiva.
Iridocorneal angle - iris-cornea junction (HE)[edit | edit source]
Description: ES – conjunctival epithelium (multilayered cylindrical) is a continuation of the corneal epithelium, c – blood vessels, SP – corneal substantia propria, dm – Descemet's membrane, zER – posterior corneal epithelium (single-layered flat epithelium), ICu – iridocorneal angle (iris-corneal), ED – iris epithelium (double-layered, both layers are pigmented), CA – camera anterior (front chamber of the eye)
Iris - Overview (HE)[edit | edit source]
Description: Ep – iris epithelium (two-layer pigmented), MSP – musculus sphincter pupillae, MDP – musculus dilator pupillae, PR – plica radians, P – pupilla (pupil), CA – anterior chamber, C – side iris facing the lens.

Ciliary Body - Overview (HE)[edit | edit source]
Description: 1 – the outer layer of the epithelium of the ciliary body, 2 – the inner layer of the epithelium of the ciliary body, 3 – the pars plicata of the ciliary body forms the aqueous humor, C – the vessels/capillaries of the ciliary body have fenestrations, CP – camera posterior (back eye chamber), Glass – sclera (white), R-PC – retina pars caeca.
Ciliated body - detail (HE)[edit | edit source]
Description: 1 – outer layer of the epithelium of the ciliary body, 2 – inner layer of the epithelium of the ciliary body, C – blood vessels.
Lens - sagittal section overview (HE)[edit | edit source]
Description: the anterior surface of the lens (A) and the posterior surface of the lens (P) meet at the equator (Ek), C – capsule (lens capsule originating from the basal lamina of the ectoderm), Ep – the epithelium is only on the anterior surface of the lens (monolayer cubic to cylindrical towards the equator),
K – cortex of the lens (contains younger lens fibers), D – medulla of the lens (contains older fibers).
Lens - detail (HE)[edit | edit source]
Description: P - rear surface of the lens, C - capsule (lens case), cv - lens fibers newly formed from cells that still contain nuclei.
Retina - Overview (HE)[edit | edit source]
Description: 1 – stratum pigmentosum retinae, 2 – layer of nuclei corresponding to rods and cones, 3 – layer of nuclei of bipolar cells, 4 – layer of nuclei of ganglion cells, 5 – layer of axons of ganglion cells, CV – corpus vitreum (vitreous ), R – retina, CH – choroid (choroid), A – arterioles, S – sclera (white blood cells).
Layers of the eyeball (HE)[edit | edit source]
Description: 1 – stratum pigmentosum retinae, CH – choroid (choroid), S – sclera (whites), A – retinal detachment is common in this location (retinal detachment is a common phenomenon in histological specimens).
