    Study Notes

    Eye Disorders

    • Eye disorders can present with various signs and symptoms.
    • Halos around lights and surrounding darkness might indicate cataracts or glaucoma.
    • Loss of peripheral vision is another potential sign of glaucoma or retinal detachment.
    • Eye pain may be a symptom of glaucoma, foreign body, or corneal abrasion.
    • Sudden changes in vision can be associated with retinal detachment, foreign body, corneal abrasion, optic neuritis, temporal arteritis, migraines, mini-strokes (TIA), or a tumor.

    Common Eye Disorders

    • Cataracts are a clouding of the natural lens of the eye. They are the leading cause of reversible blindness globally.
    • Conjunctivitis, also known as "pink eye," is a common inflammation of the conjunctiva (the membrane lining the eyelids and covering the whites of the eye). Often acute, it can be infectious or non-infectious, and might be chronic. Many cases are infectious. Infectious conjunctivitis may occur due to Staphylococcus aureus, Pseudomonas, Haemophilus influenzae, Moraxella, Gonorrhea, or Chlamydia. Viral conjunctivitis is often due to adenoviruses, or herpes virus (can be vision threatening). Infections can spread through direct inoculation via fingers or droplets.
    • Corneal abrasion is a disruption of the cornea's epithelium due to trauma from chemicals, burns, or mechanics. Injuries result from outdoor activity, occupational hazards, and lack of eye protection- including welding, painting and construction. Prolonged contact lens use can also result in corneal injury.
    • Retinal detachment is the separation of the neural retina from the choroid. This separation often occurs following trauma, hemorrhage or fluid leakage/transudation.. Annual incidence is around 10/100,000 persons.
    • Central and branch retinal artery obstruction is a blockage of these arteries leading to sudden vision loss. Causes include thrombosis, embolism, and arteritis of the central artery.
    • Hordeolum (sty) is a hair follicle or sebaceous gland abscess, whereas chalazion is a chronic inflammation of the meibomian gland. Often, this inflammation resolves on its own within 2-8 weeks.
    • Glaucoma is a group of eye diseases that damage the optic nerve. Types of glaucoma include open-angle glaucoma (gradual and insidious, increased IOP >22, normal range 10-20 mmHg), and closed-angle glaucoma (rapid increase in IOP).

    Cataracts

    • Cataracts are the leading cause of reversible blindness worldwide.
    • Early symptoms may include painless, progressive blurring of vision, glare sensitivities (especially when driving at night), difficulty reading, and the perception of halos (light rings) around lights..
    • Second sight: temporary improvement in vision can be experienced by some.
    • Some individuals experience a temporary "clearing" or "brightening" of vision.
    • Treatment options include early lens changes, micro-incision surgery, foldable lenses, and phacoemulsification.

    Conjunctivitis

    • It is a common, acute, and painful inflammation of the conjunctiva that may be infectious or non-infectious.
    • Most cases are acute but may become chronic
    • Infectious conjunctivitis often spreads through direct contact with fingers or droplets.
    • Factors that cause conjunctivitis can include allergens (like pollen, dust, and chemicals), environmental insults(e.g., wind), and medications (like antihistamines).
    • Viral conjunctivitis has a duration of 5-14 days. Often contagious if tearing lasts for at least a week.

    Corneal Abrasion

    • A corneal abrasion is the disruption of the cornea's epithelium.
    • It is commonly caused by chemical burns, mechanical trauma, or external irritants, such as outdoor activities, occupational hazards, and lack of adequate eye protection including welding, painting, and construction. Prolonged contact lens use can exacerbate injury.
    • Symptoms include sudden, intense pain, photophobia, tearing, and feeling of a foreign object in the eye..
    • Diagnosis often includes a fluorescein exam. This dye stains the abrasion and is visible under a Wood lamp.

    Retinal Detachment

    • Retinal detachment is the separation of the neural retina from the choroid, often due to trauma, hemorrhage or fluid leakage/transudation.
    • It can have annual occurrences (10/100,000 persons), and patients who have undergone cataract surgery have an increased risk(1-3%).
    • Conditions including, but not limited to, diabetes mellitus, sickle cell anemia, myopia and cataract extraction increase risk for retinal detachment.
    • Proper diagnosis and management are better left to ophthalmologists. A detailed examination of the eye is necessary for a diagnosis. Treatment includes procedures like diathermy, cryotherapy, photocoagulation, pneumatic retinopexy, and vitrectomy.

    Central and Branch Retinal Artery Obstruction

    • This condition causes a sudden loss of vision due to the blockage of the central or branch retinal artery.
    • Causes can include thrombosis, embolism, or arteritis of the central artery.
    • Risk factors include migraine, history of vasculitis, atrial fibrillation, diabetes, hypertension, inflammation, and coagulation abnormalities.

    Other Eye Disorders including management, diagnostics & subjective/objective findings

    • The sections presented above also include information on other common eye disorders such as hordeolum (sty), chalazion, and glaucoma, offering detailed insights into their presentation, diagnosis, and management.
    • For each disorder, these sections cover the etiology, symptoms, diagnostics, subjective/objective findings, and appropriate treatment, including pharmacological and non-pharmacological interventions.
    • A thorough review of systems, a complete history, and a full examination will lead to a proper diagnosis and appropriate management plan.
