Infections, inflammations or injuries of the eye and the resulting healing can cause scarring or destruction of ocular tissue, preventing light from entering the eye or preventing the images from being processed and recognized; the loss of vision may not be correctable.
Medical Definitions:
· Blepharitis: inflammation of the margins of the eyelids
· Canaliculitis: inflammation of the tubular passage in the eyelid connecting the punctum and the lacrimal sac
· Cellulitis (orbital): inflammation of the bony cavity that contains the eyeball and related structures
· Cellulitis (preseptal): inflammation of the subcutaneous tissue of the eyelids, restricted to the spaces defined by the fibrous attachments of the skin to the superior and inferior orbital rims and posteriorly by the orbital system
· Chalazion: inflammation (lipogranuloma) of the Meibomian glands within the eyelids
· Chemosis: edema of the conjunctiva
· Chorioretinitis: inflammation of the choroid and retina
· Conjunctivitis: inflammation of the tissue lining the eyelids (tarsal or palpebral conjunctiva) and eyeball (bulbar conjunctiva)
· Dacryoadenitis: inflammation of the lacrimal gland
· Dacryocystitis: inflammation of the lacrimal sac
· Endophthalmitis: inflammation of the ocular cavities and intraocular tissues
· Epiphora: overflow of tears due to faulty drainage by the outflow structures
· Episcleritis: inflammation of the episclera
· Hordeolum (internal): infected chalazion
· Hordeolum (external): stye---infection of the glands at the base of the eyelashes
· Hypopyon: accumulation of inflammatory cells and exudate in the anterior chamber, typically producing a fluid level visible by the unaided eye in the inferior part
· Iridocyclitis: inflammation of the iris and ciliary body (anterior uveitis)
· Iritis: inflammation of the iris
· Keratitis: inflammation of the cornea
· Keratitis sicca: keratoconjunctivitis sicca is caused by the reduction of the aqueous component of the preocular tear film, characterized by dryness and hyperemia of the conjunctiva and erosion of the cornea
· Panophthalmitis: inflammation of all the structures and tissues of the eye, orbit, and eyelids
· Pingueculum: yellowish subconjunctival deposit (elastotic degeneration), in the 3-9 o’clock axis
· Proptosis: forward displacement of the eyeball
· Pterygium: wedge-shaped vascularized growth (elastotic degeneration) extending onto the cornea in the 3-9 o’clock axis
· Ptosis: drooping of the upper eyelid
· Retinitis: inflammation of the retina
· Scleritis: inflammation of the sclera
· Uveitis: inflammation of the iris, ciliary body, and choroid
· Vitritis: inflammation of the vitreous
