Study Notes
Medical Terminology
-
Eye anatomy was presented, showcasing components like the retina, iris, pupil, cornea, lens, vitreous humour, and optic nerve.
-
Ophthalmo/Oculo relates to the eye, exemplified by ophthalmology (medical specialty), ophthalmologist (specialist), ophthalmoscopy (eye fundus examination), and xerophthalmia (dry eye).
-
An ophthalmoscope is a device used to examine the eye's interior via the pupil.
-
Exophthalmos describes the bulging of the eyeball outside the orbit, while endophthalmos represents displacement of the eyeball back into the orbit.
Eye Inflammation
-
Endophthalmitis infects the intraocular fluids (vitreous and aqueous).
-
Panophthalmitis causes inflammation of all eye tissues, including intraocular structures.
Eye Prefixes
-
Oculo means "eye," exemplified by ocular nerve and muscles (including extraocular muscles).
-
Miosis, a contraction of the pupil, is contrasted with mydriasis (dilation).
-
Circular muscles constrict the pupil in bright light. Radial muscles expand the pupil in dim light.
Conjunctiva
- The conjunctiva, a mucous membrane covering the sclera, can experience inflammation (conjunctivitis) or hemorrhaging.
Cornea
-
Kerato relates to the cornea. Keratitis is an inflammation of the cornea.
-
Keratoplasty is a corneal graft reconstruction procedure.
Specific Eye Structures
- Keratoconjunctivitis involves inflammation of the cornea and conjunctiva.
Iris and Ciliary Body Details
-
Irido/Iris refers to the iris. Iritis (iris inflammation) and iridectomy (surgical removal of the iris) are examples.
-
Cyclo/Ciliary body refers to the ciliary body. Cyclits (inflammation of the ciliary body) and iridocyclitis (inflammation of both the iris and ciliary body) are specific cases.
-
Cycloplegia is paralysis of the ciliary body, with cyclospasm being its contraction.
Eyelids Details
- Blephar relates to the eyelid. Blepharitis is an eyelid inflammation.
Other Eye Conditions
-
Cataract is a progressive lens opacity.
-
Glaucoma is an eye disorder marked by elevated intraocular pressure, potentially leading to optic nerve atrophy and blindness.
-
Myopia (nearsightedness) involves parallel rays focusing in front of the retina.
-
Hypermetropia (farsightedness) has parallel rays focused behind the retina.
-
Presbyopia, similar to hypermetropia, is an age-related condition.
