EENT APEA Questions with Correct Answers |
Latest 2026
Refractive Errors
The most common cause of visual acuity problems. It occurs when the shape of the eye prevents
light from focusing directly on the retina.
Myopia
(nearsightedness) Light focuses in front of the retina.
Hyperopia
(farsightedness): Light focuses behind the retina.
Astigmatism
Irregular curvature of the cornea or lens.
Presbyopia
Age-related loss of accommodation (focus on near objects).
Retinal Disorders
Conditions like macular degeneration, diabetic retinopathy, and retinal detachment can
significantly affect visual acuity.
Cataracts
Clouding of the lens, leading to decreased clarity and sharpness of vision.
Glaucoma:
,Elevated intraocular pressure damages the optic nerve, affecting vision.
Optic Neuritis
Inflammation of the optic nerve, often associated with multiple sclerosis.
A visual acuity of ____ is considered normal.
A visual acuity of 20/20 is considered normal.
assessment for visual acuity
Blurred Vision: Common in refractive errors, cataracts, and diabetic retinopathy.
Loss of Central Vision: Often seen in macular degeneration or diabetic retinopathy.
Peripheral Vision Loss: Common in glaucoma.
Visual Disturbances: Like flashes of light or floaters, which could be indicative of retinal issues
or ocular migraines.
Pain: Associated with conditions like optic neuritis, corneal abrasions, or acute angle-closure
glaucoma.
diagnostic procedures for visual acuity
• Visual Acuity Test: Standard assessment using the Snellen chart (measuring the smallest line
the patient can read from a fixed distance).
• Pupil Examination: To assess for afferent pupillary defects (e.g., in optic neuritis).
• Fundoscopy (Ophthalmoscopy): To examine the retina and optic nerve head.
• Tonometry: Measures intraocular pressure for glaucoma.
• Refraction Test: Determines refractive errors (myopia, hyperopia, astigmatism).
• Amsler Grid: Used to detect macular degeneration.
,• Fluorescein Angiography: For diabetic retinopathy or retinal vascular disorders.
Optical Coherence Tomography (OCT): To assess the macula and retina for conditions like
macular degeneration and diabetic retinopathy.
management for visual acuity disorders
• Cataracts: Surgical removal of the cataract and replacement with an intraocular lens.
• Glaucoma: Medications (beta-blockers, prostaglandin analogs, alpha agonists) to reduce
intraocular pressure; in some cases, surgical intervention may be required.
• Macular Degeneration: Management includes lifestyle changes (e.g., diet, smoking cessation),
anti-VEGF therapy (for wet macular degeneration), and laser therapy.
• Diabetic Retinopathy: Blood sugar control, laser therapy, and intravitreal injections of anti-
VEGF agents or steroids.
• Optic Neuritis: Corticosteroids for acute inflammation, often associated with MS.
• Retinal Detachment: Surgical intervention (e.g., vitrectomy, scleral buckle).
Uveitis: Corticosteroids and immunosuppressive therapy.
what is Retinal Artery Occlusion (RAO)
• Cause: Blockage of the retinal artery (embolisms or clots).
• Symptoms: Sudden, painless vision loss in one eye, often with a "cherry red spot" on
fundoscopy.
• Risk Factors: Atherosclerosis, hypertension, diabetes, and blood clots.
• Treatment: Immediate action is needed—ocular massage, medications, or surgery to improve
blood flow.
Key Point: Sudden, painless vision loss with a cherry red spot.
, what is Retinal Detachment (RD):
• Cause: Retinal layer separates from the underlying tissue, often due to a tear or hole.
• Symptoms: Gradual loss of vision, described as a "curtain" over part of the visual field, plus
flashes and floaters.
• Risk Factors: High myopia, trauma, past eye surgery, or family history.
• Treatment: Urgent surgery—laser therapy, cryotherapy, or vitrectomy to reattach the retina.
• Key Point: Progressive vision loss, flashes, floaters, and "curtain" effect.
Key Differences:
• RAO: Sudden vision loss, "cherry red spot" on the retina.
RD: Progressive vision loss, flashes, floaters, and "curtain" over the field of vision.
cataract patho
Cataracts are a clouding or opacity of the lens in the eye, leading to impaired light transmission
to the retina.
The lens is primarily made up of water and proteins, proteins can break down or clump together,
leading to cloudiness. SLOWLY and GRADUAL VISION CHANGES
cataract symptoms
• Blurry or cloudy vision: Vision becomes increasingly hazy or foggy.
• Glare and halos:
• Double vision
DX:
• Visual acuity test: To measure the sharpness of vision.
