1.
What is the condition when light rays focus in front of the retina instead of on? Also when looking through glasses of someone with this condition everything will appear small.
Correct Answer
B. Myopia
Explanation
Myopia is called nearsightedness and the distance between the cornea and the retina may be too long.
2.
What condition occurs when light passing through the cornea is not properly focused on the retina and distance and close vision may appear blurry?
Correct Answer
C. Astigmatism
Explanation
cornea is shaped like a football
3.
A 41 y/o males comes into your office complaining that he can't see as well as he used to when reading a book but his vision is fine for distance. What is the most likely Dx?
Correct Answer
A. Presbyopia
Explanation
Presbyopia is the most likely diagnosis for a 41-year-old male who complains of difficulty seeing close objects, such as when reading a book, but has no issues with distance vision. Presbyopia is a common age-related condition where the lens of the eye loses its flexibility, leading to difficulty focusing on close objects. This condition typically starts to develop around the age of 40 and gradually worsens with age. Hyperopia, nystagmus, and strabismus are less likely in this case as they do not specifically match the symptoms described.
4.
What is the condition called when the distance between the cornea and the retina may be too short?
Correct Answer
D. Hyperopia
Explanation
Hyperopia, also known as farsightedness, is a condition where the distance between the cornea and the retina is too short. This causes difficulty in focusing on near objects, while distant objects appear clearer. People with hyperopia may experience blurred vision, eye strain, and headaches when performing close-up tasks. This condition can be corrected with prescription glasses or contact lenses that help to compensate for the shorter distance between the cornea and retina, allowing for clearer vision at all distances.
5.
What typically results from acquired ocular misalignment?
Correct Answer
B. Diplopia
Explanation
Acquired ocular misalignment refers to a condition where the eyes are not properly aligned, causing double vision or diplopia. This means that a person sees two images of a single object instead of one. Strabismus is a medical term for misalignment of the eyes, but it is not the result of acquired ocular misalignment. Pinguecula and pterygium are both conditions that involve the growth of abnormal tissue on the eye, but they are not related to ocular misalignment. Therefore, the correct answer is diplopia, which is a common symptom of acquired ocular misalignment.
6.
What is jiggling of the eyes called?
Correct Answer
A. Nystagmus
Explanation
Nystagmus refers to the involuntary jiggling or shaking of the eyes. It is a condition characterized by rapid, repetitive, and uncontrolled eye movements that can occur horizontally, vertically, or in a rotary pattern. Nystagmus can be congenital or acquired and may be caused by various underlying factors, such as neurological disorders, inner ear problems, or certain medications. The condition can affect vision and may result in reduced visual acuity, dizziness, and difficulty with depth perception. Treatment options for nystagmus depend on the underlying cause and may include medications, surgery, or the use of visual aids.

A 30 y/o chronic tanner presents to your office for an eye exam because she has something in her eye that she can't get out. Upon examination, you see a triangular encroachment of the pinguecula onto the cornea bilaterally. What is most likely the Dx?
Correct Answer
A. Ptyerigium
Explanation
The most likely diagnosis in this case is pterygium. Pterygium is a growth of fleshy tissue on the conjunctiva, usually caused by excessive exposure to UV radiation. It commonly occurs in individuals who frequently tan or spend a lot of time in the sun. The triangular encroachment of the pinguecula onto the cornea is a characteristic finding of pterygium. Pinguecula, on the other hand, is a yellowish bump on the conjunctiva that does not invade the cornea. Chalazion and hordeolum are both eyelid conditions and not related to the symptoms described.
8.
A patient presents to your office with a painless, slowly enlarging bump on the eyelid. What is the treatment?
Correct Answer
D. Warm compresses
Explanation
chalazion- a painless, slowly enlarging bump on the eyelid that is formed by inflammation of the meibomian glands
9.
A 35 y/o male presents to your office because he thinks he got "pink eye" from his daughter. He awoke with a red, painful, swollen eye. Upon examination you see infection in the deeper structures behind the eye. What is most likely the Dx?
Correct Answer
B. Orbital Cellulitis
Explanation
The eye may be pushed forward and vision may be affected. Treatment must be taken seriously and requires urgent hospitalization and antibiotic treatment.
10.
A patient recently diagnosed with a herpes virus presented to the ophthalmologist with diplopia and painful swelling of the lateral third of the upper eye lid. What is most likely the Dx?
Correct Answer
C. Dacryoadenitis
Explanation
Dacryoadenitis- Uncommon, inflammatory disorder of the lacrimal gland, located under the lateral portion of the upper lid. Most common causes are mumps and herpes virus/
11.
A patient presents to the ED because he noticed his eye "didn't look right" after being involved in a bar fight the night before. The patient received multiple hits to the face and has decreased vision in the injured eye. Upon exam you find that he has increased intraocular pressure. What is most likely the Dx?
Correct Answer
D. HypHema
Explanation
The reason the patient's eye "didn't look right" is because it had blood in the anterior chamber.
12.
What is characterized by headache, jaw claudication, polymyalgia rheumatic, visual abnormalities, and markedly elevated erythrocyte sedimentation rate?
Correct Answer
B. Giant cell arteritis
Explanation
Giant cell arteritis is characterized by headache, jaw claudication, polymyalgia rheumatica, visual abnormalities, and markedly elevated erythrocyte sedimentation rate. This condition is an inflammatory disease that affects the medium and large arteries, particularly the temporal arteries. It commonly occurs in individuals over the age of 50 and can lead to complications such as blindness if left untreated. Symptoms such as headache, jaw pain, and visual abnormalities are common in giant cell arteritis due to the inflammation of the blood vessels supplying the head and eyes. The elevated erythrocyte sedimentation rate is a non-specific marker of inflammation often seen in this condition.
13.
What is painless, passive bilateral disk swelling associated with increased intacranial pressure? It is associated with nonspecific symptoms of headache, nausea, vomiting, and diplopia from abducens nerve palsy.
Correct Answer
A. Papilledema
Explanation
Papilledema refers to painless, passive bilateral disk swelling associated with increased intracranial pressure. It is characterized by nonspecific symptoms such as headache, nausea, vomiting, and diplopia from abducens nerve palsy. This condition is commonly seen in conditions like brain tumors, intracranial hemorrhage, or meningitis, where increased pressure in the skull compresses the optic nerve, leading to swelling of the optic disk. Acute angle closure glaucoma, retinal detachment, and central retinal artery occlusion do not typically present with painless, passive bilateral disk swelling.
14.
A 65 y/o female presents to the ED because she has just experenced a rapid onset of severe pain with profound visual loss. While talking to the woman you find out that she sees "halos around lights". Upon examination see document: red eye, cloudy cornea, dilated pupil, and the eye is hard to palpate. What is the most likely Dx?
Correct Answer
D. Acute angle closure glaucoma
Explanation
The given symptoms of sudden severe pain, profound visual loss, halos around lights, red eye, cloudy cornea, dilated pupil, and a hard to palpate eye are indicative of acute angle closure glaucoma. This condition occurs when the drainage angle of the eye becomes blocked, leading to a sudden increase in intraocular pressure. This can cause symptoms such as severe pain, visual disturbances, and redness. The cloudy cornea and dilated pupil are also characteristic findings of acute angle closure glaucoma. Retinal detachment and acute uveitis may present with some similar symptoms but are less likely based on the given information. Acute open-angle glaucoma is also less likely as it does not typically present with sudden onset and profound visual loss.
15.
How will a patient most likely describe retinal detachment?
Correct Answer
C. Curtain coming down over the eyes
Explanation
A patient with retinal detachment will most likely describe the sensation as a "curtain coming down over the eyes." This description refers to the gradual or sudden loss of vision in one eye, as if a curtain or veil is obstructing their vision. It is a common symptom of retinal detachment, which occurs when the retina separates from the underlying tissue. This detachment can lead to permanent vision loss if not promptly treated.
16.
The ophthalmoscopic exam revealed: pallid swelling of the retina and cherry-red spot at the fovea. What is the most likely Dx?
Correct Answer
D. Central retinal artery occlusion
Explanation
The ophthalmoscopic exam findings of pallid swelling of the retina and cherry-red spot at the fovea are characteristic of central retinal artery occlusion. This condition occurs when the blood flow to the retina is blocked, usually due to a blood clot. The pallid swelling of the retina indicates ischemia, or lack of blood supply, while the cherry-red spot at the fovea is caused by the contrast between the pale retina and the normal color of the macula. Cataract, open-angle glaucoma, and macular degeneration would not present with these specific ophthalmoscopic findings.
17.
Glaucoma is acquired optic nerve atrophy often associated with increased intraocular pressure. What type is a dysfunction of the aqueous humor drainage system with no visible pathology to the anterior chamber angle?
Correct Answer
A. Open-angle
Explanation
Most patients with open-angle glaucoma have normal intaocular pressures
18.
What occurs when abnormal blood vessels grow under the retina affecting your central vision?
Correct Answer
C. Macular degeneration
Explanation
Macular degeneration is a condition in which abnormal blood vessels grow under the retina, leading to damage and loss of central vision. This condition primarily affects older adults and is a leading cause of vision loss. It can result in blurred or distorted vision, difficulty reading or recognizing faces, and a dark or empty area in the center of the visual field. Diabetic retinopathy is a condition caused by diabetes that affects the blood vessels in the retina, while high blood pressure can damage the blood vessels throughout the body, including those in the eyes. Presbyopia is a natural age-related condition that affects near vision.
19.
Macular degeneration and presbyopia are both conditions that are part of the natural aging process.
Correct Answer
A. True
Explanation
Presbyopia >40 y/o- lens not as flexible, need bifocals Macular degeneration >65 y/o- macula may lose effectiveness or abnormal blood vessels grow under the retina
20.
A DM patient will most likely have what disease/condition?
Correct Answer
B. Damage to fragile blood vessels inside the retina.
Explanation
damage to fragil blood vessels inside the retina aka Diabetic Retinopathy
Optic neuritis- most common cause is demyelination
