Study Notes

Eye Disorders

Assessment and management of patients with eye, ear, and nose disorders is the topic of the lecture.
Objectives include identifying eye, nose, and ear structures and their functions; identifying causes and risk factors for eye, nose, and ear problems; and discussing clinical features, examinations, and management of common eye, nose, and ear problems, as well as discharge instructions.

Eye Anatomy

The eye has structures like the eyelid, pupil, sclera, iris, ciliary body, cornea, vitreous humor, lens, and ciliary body.
The cornea has layers, including mucous, watery, and oil layers.
The lens is the clear structure that focuses light.
The aqueous humor provides nutrition and maintains pressure.

Definitions of Eye Terms

Aqueous humor: Fluid within the eye, providing nutrition and maintaining pressure.
Optic nerve: Bundle of nerve fibers carrying visual messages from the retina to the brain.
Retina: Light-sensitive layer lining the back of the eye.
Trabecular meshwork: Spongy tissue near the cornea, allowing aqueous humor drainage.
Intraocular pressure (IOP): Measurement of force exerted by aqueous humor on eye.

Common Eye Health Problems: Conjunctivitis

Conjunctivitis is inflammation of the conjunctiva (thin, clear tissue covering the white part of the eye and lining the inner eyelids).
Symptoms include watery or pus-like discharge, itchy or burning eyes, puffy eyelids, and redness.
Causes include viruses, bacteria, allergens, smoke, dust, and UV light.
Management depends on the cause.

Common Eye Health Problems: Cataracts

Cataracts are cloudy areas in the eye lens.
Symptoms include blurry vision, decreased vision clarity, difficulty seeing in bright light, and sensitivity to light.
Causes include aging, family history, certain medical conditions, and injury.
Management can be medical (glasses, contact lenses, etc.) and surgical (lens replacement).

Common Eye Health Problems: Glaucoma

Glaucoma is characterized by optic nerve damage caused by increased intraocular pressure (IOP).
Risk factors include age, family history, certain medical conditions, and ethnicity.
Symptoms include painless vision loss and problems with peripheral vision.
Management involves medical therapy (medications) and/or surgical interventions.

Ear Infections

Otitis media (OM) is inflammation of the middle ear, often caused by infection.
Types of OM include acute otitis media (sudden infection with fluid/pus buildup) and chronic otitis media (ongoing/repeated infections).
Symptoms in adults may include pain, drainage, muffled hearing, fever, and symptoms of upper respiratory infection.
Causes include viral and bacterial infections and respiratory illnesses.
Risk factors for OM may include age, family history, immune deficiency, and exposure to pathogens.
Diagnosing OM involves patient history, clinical examination, and specialized testing.
Management includes antibiotics (for bacterial), pain relievers, decongestants, and sometimes ear tubes (for chronic cases).

Nose Problems: Deviated Septum

A deviated septum is a condition where the nasal septum (the thin wall separating the nostrils) is displaced from the center, leading to partial airway obstruction.
Symptoms include breathing difficulties, nasal congestion, repetitive sneezing, sinus infections, facial pain, headaches, snoring, nosebleeds, and loss of sense of smell.
Causes of deviated septums include birth defects, injury, and infections.
Diagnosis can be made via patient history, physical examination using a pen torch, and possibly x-rays or CT scans.
Treatment includes medical management (decongestants, antihistamines) and surgical repair (septoplasty or rhinoplasty)
