Glossary of OCULAR PROSTHETICS

Anophthalmia
Absence of the eyeball


Adnexa (Ocular adnexa)
Tissues surrounding (the eye i.e. the eyelids, canthi, and lacrimal apparatus)


Alginate
Powdery product that solidifies within a minute after mixing with water to make a paste.

Bio integrated orbital implant
Orbital Implant that is allows body tissues to grow inside due to its porous nature

Canthus (Plural: Canthi)
Angle where upper and lower eyelids meet

Conformer
A concave plastic piece that is inserted following enucleation or evisceration or socket reconstruction surgery to retain the fornices. It has draining holes that do not allow pooling of secretion behind

Custom

Designed for the individual
Congenital

Present since birth
Cornea
The clear convex portion of the eyeball
Dermis Fat Graft
Tissue containing Dermis (a layer of skin) and Fat (adipose tissue) that is removed from one part of the body (usually buttock) to augment volume and add surface to the contracted socket.
Enucleation
Surgical procedure to remove the eyeball as done in cases of cancer of eye or badly damaged eye in trauma.
Evisceration
Surgical procedure to remove the inner contents of the eyeball and cornea leaving the outer coat of sclera.
Extrusion
Exposure of the inner structure/implant due to necrosis of overlying tissue.
Fornix (Plural: Fornices)
The peripheral space in the eye socket behind the eyelids.

Implant
An inert foreign or autogenous body that is put within living tissue.
Impression tray
A concave plastic tray that is place in the fornices and alginate material is instilled behind it to get an impression of the socket.
Integrated
A foreign body that has body tissue growing within.
Microphthalmos
Condition of having a smaller eyeball at the time of birth.
Mold
A replica of any space or cavity.
Mono ocular
Related to one eye.

Orbit
The Bony cavity housing the eye and related structures

Phthisis/phthisical

Plastics
Repair work on the body tissue.
Polymethylmethacrylate (PMMA)
A special type of plastic that is very inert biologically and polymer of methacrylate.
Posterior surface
Back surface.
Protein deposits
Accumulation of biological material over the surface of the artificial eye.
Reconstruction Surgery
Repair of the damaged body structure by specialized surgical techniques.

Retinoblastoma

A kind of cancer arising from the inner layers of eye and if not treated in time can be fatal.


Superior sulcus defect
Hollow or depression under the eyebrow due to loss of the fatty tissue in the orbit
