EYE ANTIOXIDANTS

👨‍⚕️ Eye antioxidants help protect eyes from oxidative stress and damage.

Key antioxidants:

  1. Lutein: Found in retina, filters blue light
  2. Zeaxanthin: Protects macula
  3. Vitamin C: Supports collagen production
  4. Vitamin E: Protects cell membranes
  5. Zinc: Essential for retina health

Benefits:

  1. AMD prevention: Reduces risk
  2. Cataract prevention: May slow progression
  3. Eye health: Supports overall vision

Food sources:

  1. Leafy greens: Spinach, kale
  2. Colorful fruits: Berries, citrus
  3. Nuts and seeds: Almonds, sunflower seeds
  4. Fatty fish: Salmon, tuna
LISAMINE GREEN STAINING

👨‍⚕️ Lissamine Green staining test assesses ocular surface damage, particularly conjunctival epithelial damage.

Procedure:

  1. Apply anesthetic drops (optional)
  2. Place Lissamine Green drops in eye
  3. Examine under white or blue light

Interpretation:

  • Staining pattern: Indicates damage location/severity
  • Scoring systems: Grade staining (e.g., Oxford scale)

Uses:

  1. Dry eye disease: Evaluates conjunctival staining
  2. Ocular surface disorders: Identifies damaged areas
  3. Conjunctival disorders: Assesses inflammation
FLOURESCEIN ANGIOGRAPHY

👨‍⚕️ Fluorescein angiography is a diagnostic test that uses fluorescein dye and a specialized camera to visualize the retinal blood vessels.

Key uses:

  1. Diabetic retinopathy: Detects leakage, neovascularization
  2. Macular degeneration: Identifies abnormal blood vessels
  3. Retinal vascular occlusions: Diagnoses blockages
  4. Tumors: Highlights abnormal vessels

Procedure:

  1. Inject fluorescein dye into arm vein
  2. Take photographs as dye circulates
  3. Capture early and late-phase images

Findings:

  • Leakage: Dye escape from vessels
  • Blockage: Dark areas (hypofluorescence)
  • Neovascularization: Abnormal vessels

Precautions:

  • Nausea, yellow skin discoloration (temporary)
  • Allergic reactions (rare)
  • Pregnancy/breastfeeding: Use cautiously
CASE HISTORY

A case history is a detailed record of a patient’s medical history, symptoms, and treatment plan. For eye care, it includes:

Key components:

  1. Chief complaint: Patient’s main issue (e.g., blurred vision)
  2. History of present illness: Symptoms, duration, severity
  3. Medical history: Systemic conditions, medications
  4. Ocular history: Previous eye issues, surgeries
  5. Family history: Relevant eye conditions
  6. Social history: Lifestyle, occupation, habits
  7. Medications: Current medications, allergies

Purpose:

  1. Accurate diagnosis
  2. Personalized treatment plan
  3. Monitoring progress
REFRACTION

🔍 Refraction is the bending of light as it passes through different mediums (e.g., air, lens, cornea). In the eye, it focuses light onto the retina.

Types:

  1. Emmetropia: Normal vision.
  2. Myopia (nearsightedness): Blurred distance vision.
  3. Hyperopia (farsightedness): Blurred near vision.
  4. Astigmatism: Distorted vision.
  5. Presbyopia: Age-related near vision loss.

Tests:

  • Visual acuity: Snellen chart.
  • Autorefraction: Objective measurement.
  • Subjective tests: Lens power adjustment.

Corrections:

  • Glasses/contact lenses: Adjust refractive power.
  • Surgery: LASIK, PRK, etc.

CYCLOPLEGIC REFRACTION

Cycloplegic refraction is an eye exam that temporarily paralyzes the ciliary muscle, relaxing the eye’s focusing power. This helps determine the true refractive error, especially in children or those with accommodative esotropia.

Key uses:

  1. Accurate prescription for glasses or contact lenses
  2. Diagnosing amblyopia or strabismus
  3. Managing accommodative esotropia
CYCLOPLEGIA

🔍 Cycloplegia is the temporary paralysis of the ciliary muscle, which controls the eye’s focusing (accommodation).

Key effects:

  1. Blurry near vision
  2. Difficulty focusing on close objects
  3. Pupil dilation (mydriasis)
  4. No pain, but uncomfortable for reading/near work

Common causes:

  1. Medications: Cyclopentolate, atropine (used in eye exams)
  2. Infections: Viral (e.g., herpes zoster)
  3. Trauma
  4. Toxins (e.g., botulinum)
  5. Conditions: Adie’s tonic pupil

Management:

  • Reversible (lasts hours–days, depending on cause)
  • Use glasses for near tasks
  • Avoid driving until resolved
  • Consult an eye doctor if persistent 😎.
MIOSIS

Miosis is the constriction of the pupil. It’s the opposite of mydriasis 😊.

Common causes:

  1. Bright light
  2. Medications: Opioids (e.g., morphine), eye drops (e.g., pilocarpine)
  3. Conditions: Horner’s syndrome, iritis, or neurological disorders
  4. Aging
  5. Substance use: Certain drugs (e.g., heroin)

Effects:

  1. Reduced light entry → dim vision in low light
  2. Increased depth of field (improved near vision)
  3. Headache or eye strain
MYDRIASIS

Mydriasis is the dilation of the pupil, often caused by:

  • Low light conditions
  • Certain medications (e.g., atropine)
  • Medical conditions (e.g., Adie’s pupil)
  • Substance use (e.g., stimulants)
  • Trauma or injury

Effects:

  1. Increased light sensitivity
  2. Blurred vision
  3. Difficulty focusing
NAVIGATING DRY EYE SYNDROME VIA NUTRITION

Managing dry eyes with diet involves incorporating foods rich in nutrients that support eye health. Here are some tips:

  • Omega-3 fatty acids: Include foods like salmon, sardines, walnuts, and chia seeds to reduce inflammation and promote tear production.
  • Vitamin A-rich foods: Eat carrots, sweet potatoes, spinach, and kale to support the health of the cornea.
  • Vitamin C-rich foods: Consume citrus fruits, bell peppers, and tomatoes to boost collagen production and tear quality.
  • Stay hydrated: Drink plenty of water throughout the day to keep your eyes moist.
  • Limit: Avoid foods high in sugar, salt, and processed ingredients that can exacerbate dry eyes.

Some specific foods that can help:

  • Salmon
  • Walnuts
  • Chia seeds
  • Spinach
  • Kale
  • Carrots
  • Sweet potatoes
  • Citrus fruits
  • Bell peppers.
