Study Notes
Eye and Ear Anatomy Terms
- kerat/o: Refers to hardness, often used in the context of the cornea.
- blephar/o: Denotes the eyelid, crucial for protecting the eye.
- opt/o: Pertains to the eye and vision; central to the study of optics.
- myring/o / tympan/o: Relates to the eardrum, which vibrates in response to sound waves.
- ot/o: Refers to the ear, integral to hearing and balance.
Vision-Related Conditions
- -opia: Indicates various vision conditions, highlighting the nature of visual impairment.
- myopia: Known as nearsightedness; a condition where close objects are seen clearly, but distant ones are blurry.
- hyperopia: Refers to farsightedness; far objects are seen clearly, but close ones are blurry.
- astigmatism: A refractive error caused by uneven cornea curvatures, impairing focus.
- presbyopia: Age-related condition affecting the ability to see close objects clearly.
Ear-Related Conditions
- otitis media: Inflammation of the middle ear, commonly seen in children and can cause ear infections.
- labyrinthitis: Inflammation of the inner ear labyrinth, resulting in dizziness and vertigo.
- tinnitus: A perception of noise, often described as ringing in the ears, indicating potential hearing loss or damage.
Surgical Procedures
- myringotomy: Surgical incision of the eardrum, typically to relieve pressure or drain fluid.
- retinopexy: Laser procedure to repair a detached retina, crucial for preserving vision.
- mastoidectomy: Surgical removal of mastoid air cells, often related to chronic ear infections.
- iridectomy: Surgery performed to treat closed-angle glaucoma by removing a portion of the iris.
Important Structures
- sclera: The rigid outer layer of the eye, providing shape and protection to internal structures.
- retina: Contains light-sensitive cells crucial for vision; located at the back of the eye.
- cochlea: A spiral-shaped structure in the inner ear responsible for hearing.
- optic disk: Also known as the blind spot, where the optic nerve enters the eye, devoid of photoreceptors.
Other Medical Terms
- presbycusis: Age-related hearing loss affecting high-frequency sounds, a common condition in older adults.
- xerophthalmia: Dryness of the eye surfaces, potentially leading to discomfort and vision problems.
- lacrimitis: Inflammation of the lacrimal duct, can affect tear production and drainage.
- periorbital edema: Swelling around the eyes, often linked to various health issues, including allergies.
Sinus and Vision Testing
- Snellen chart: Tool used to measure visual acuity, essential in eye examinations.
- diopter: Unit used to express the refractive power of lenses; helpful in prescription glasses.
Conditions Affecting Eye Health
- glaucoma: Progressive optic nerve damage often assessed through visual field tests to identify peripheral vision loss.
- hordeolum: Commonly known as a stye, is an infection of the eyelid glands.
- emmetropia: Normal eye condition where light focuses correctly on the retina, ensuring clear vision.
Miscellaneous Terms
- cerumen: A natural earwax, serving to protect and lubricate the ear canal.
- blepharitis: Inflammation of the eyelids, which can cause redness and irritation.
- aphakia: Absence of the lens of the eye, often due to surgery, leading to significant vision changes.
These concise notes encapsulate essential terms and conditions related to eye and ear health that are important for understanding anatomy, pathophysiology, and clinical procedures.
