Infection: An invasion by microorganisms anywhere in the body.

 

Interrupted: Surgical sutures that are separate, rather than continous.

 

Intraocular: Within the eyeball.

 

Intrascleral: Within the sclera.

 

Laxity: A lack of suspension, usually in the eyelids.

 

Lids: Eyelid.

 

Limbus: The outer rim of the anterior chamber, where the clear cornea meets the white sclera, site of the drainage of aqueous humor and the attachment of the iris to the ciliary body.

 

Malignant: any cancerous tumor sending seed cells to other body parts (usually via the lymphatic system) which produce additional tumors of the originating tissue type.

 

Meningitis: Inflammation of the membranes of the brain or spinal cord.

 

Motility: In ocularistry, the degree of movement in the socket transferred to the prosthesis.

Ocularist: A professional maker of artificial eyes.

 

Ointment: A medicated gel, usually mixed in petroleum jelly.

 

Ophthalmologist: A medical doctor (MD) trained for over seven years to specialize in diseases of the eye.

 

Opiate: Any medication containing opium derivatives. 

 

Optic nerve: Large nerve that carries electrical signals from the retina to the brain.

 

Orbit: Cone-shaped bony confines of the eye and eye muscles.

 

Orbital Cellulitis: Infection of tissues in the orbit that produces swelling, bulging,  and redness, often spreading to the orbit from the surrounding sinuses.

 

Pathologic Specimen: Tissues from any sampling (biopsy) or surgery that are examined by microscope.

 

Peribulbar: Closely surrounding the eyeball.

 

Periorbita: Dense layer of connective tissue that lines the orbital bones.

 

Periotomy: In ophthalmic surgery, an incision around the limbus.

 

Prolapsing: A falling-out of any tissue or organ.

 

Prosthesis: The replacement of any body part by an artificial one. 

 

Proteins: Amino acids or derivatives that can normally aggregate onto contact lenses or ocular prostheses. 

 

Ptosis: A drooping of the eyelid(s).

 

Rectus muscles: Four extraocular muscles that mainly pull straight; Plural: recti

 

Retinal artery: Branch of the ophthalmic artery that feeds the inside of the eye, and is visible through the iris.

 

Retrobulbar: Behind the eyeball.

 

Sclera: White outer layer of the eyeball.

 

Scleral Cover Shell: A thin ocular prosthesis worn over a non-seeing eye.

 

Sclerotomy: An incision through the sclera. 

 

Spherical acrylic implant: A plastic ball-shaped replacement after removal of the eyeball that does not allow tissues to grow into it.

 

Steroid: A drug treatment to control inflammation.

 

Subarachnoid: Beneath the arachnoid membrane surrounding of the brain, optic nerve, and spinal cord. 

 

Sulcus: In ocularistry, a recession of the upper eyelid or enophthalmos after the healing of surgery.

 

Suspensory Ligaments: Fibrous structures that hold the eyeball in place as it rotates.

 

Sutures: The surgical material closing two edges; in ocularistry, these are usually the closing the conjunctival socket.

 

Sympathetic Ophthalmia: Auto-immune inflammation of the pigmented uvea once thought to cause a similar uveitis in the other (sympathizing) eye.

 

Tamponade: Pressure on a wound or body cavity, especially to stop bleeding.

 

Tenonís capsule: Thin, elastic membrane that covers the eyeball from the cornea to the optic nerve, loosely attached to the sclera and extraocular muscles.

 

Tetracaine: One anesthetic, applied as eye-drops.

 

Treatments: Any remedy or manipulation designed to aid a patient.

 

Tumor Cells: Tissues of a cancerous lesion that may spread and grow (malignant) elsewhere in the body, usually carried by the lymphatic system.

 

Uveal pigment: Dark melanin inside cells of the iris, ciliary body, or choroids.

 

Uveal Prolapse: Iris, ciliary body, or choroids tissue abnormally outside the pressurized eyeball from injury or incision.
