Which of the following is a common symptom of retinal detachment?

  1. Blurred vision

  2. Flashes of light

  3. Floaters

  4. All of the above


Correct Option: D
Explanation:

Retinal detachment can cause blurred vision, flashes of light, floaters, and sometimes a curtain-like shadow over the field of vision.

What is the leading cause of retinal detachment?

  1. Trauma

  2. Age-related changes

  3. Diabetes

  4. High blood pressure


Correct Option: B
Explanation:

Age-related changes in the vitreous humor, the gel-like substance that fills the eye, can cause it to pull away from the retina, leading to retinal detachment.

Which retinal disorder is characterized by the growth of abnormal blood vessels in the retina?

  1. Diabetic retinopathy

  2. Age-related macular degeneration

  3. Retinal detachment

  4. Glaucoma


Correct Option: A
Explanation:

Diabetic retinopathy is a complication of diabetes that affects the blood vessels in the retina. It can lead to the growth of abnormal blood vessels, which can cause bleeding, leakage, and scarring in the retina.

What is the most common form of age-related macular degeneration?

  1. Dry AMD

  2. Wet AMD

  3. Geographic atrophy

  4. Stargardt disease


Correct Option: A
Explanation:

Dry AMD is the most common form of age-related macular degeneration. It is characterized by the accumulation of drusen, small yellow deposits, in the macula, the central part of the retina responsible for sharp central vision.

Which retinal disorder is characterized by the formation of scar tissue in the macula?

  1. Diabetic retinopathy

  2. Age-related macular degeneration

  3. Retinal detachment

  4. Glaucoma


Correct Option: B
Explanation:

Age-related macular degeneration can lead to the formation of scar tissue in the macula, which can result in loss of central vision.

What is the leading cause of blindness in children?

  1. Retinopathy of prematurity

  2. Congenital cataracts

  3. Glaucoma

  4. Strabismus


Correct Option: A
Explanation:

Retinopathy of prematurity (ROP) is a potentially blinding eye disease that affects premature infants. It is caused by the abnormal development of blood vessels in the retina.

Which retinal disorder is characterized by the accumulation of fluid beneath the retina?

  1. Diabetic retinopathy

  2. Age-related macular degeneration

  3. Retinal detachment

  4. Glaucoma


Correct Option: C
Explanation:

Retinal detachment occurs when the retina separates from the underlying layer of the eye, the choroid. Fluid can accumulate beneath the retina, causing it to detach further.

What is the treatment for retinal detachment?

  1. Laser surgery

  2. Vitrectomy

  3. Scleral buckle

  4. All of the above


Correct Option: D
Explanation:

The treatment for retinal detachment depends on the severity of the detachment and the underlying cause. It may involve laser surgery, vitrectomy, scleral buckle, or a combination of these procedures.

Which retinal disorder is characterized by the loss of peripheral vision?

  1. Glaucoma

  2. Retinitis pigmentosa

  3. Stargardt disease

  4. Usher syndrome


Correct Option: A
Explanation:

Glaucoma is a group of eye diseases that damage the optic nerve, which connects the eye to the brain. It can lead to loss of peripheral vision, and if left untreated, can progress to blindness.

What is the most common inherited retinal disorder?

  1. Retinitis pigmentosa

  2. Stargardt disease

  3. Usher syndrome

  4. Leber congenital amaurosis


Correct Option: A
Explanation:

Retinitis pigmentosa is the most common inherited retinal disorder. It is a group of genetic conditions that affect the retina, causing progressive loss of vision.

Which retinal disorder is characterized by the accumulation of lipofuscin, a yellow pigment, in the retinal cells?

  1. Stargardt disease

  2. Retinitis pigmentosa

  3. Usher syndrome

  4. Leber congenital amaurosis


Correct Option: A
Explanation:

Stargardt disease is an inherited retinal disorder characterized by the accumulation of lipofuscin in the retinal cells. It typically affects children and young adults, causing progressive loss of central vision.

What is the treatment for Stargardt disease?

  1. There is no cure

  2. Gene therapy

  3. Vitamin A supplements

  4. Low-vision aids


Correct Option: A
Explanation:

Currently, there is no cure for Stargardt disease. Treatment focuses on managing the symptoms and providing low-vision aids to help patients with their daily activities.

Which retinal disorder is characterized by the combination of hearing loss and vision problems?

  1. Usher syndrome

  2. Retinitis pigmentosa

  3. Stargardt disease

  4. Leber congenital amaurosis


Correct Option: A
Explanation:

Usher syndrome is a group of genetic disorders that affect both hearing and vision. It can cause progressive hearing loss, retinitis pigmentosa, and balance problems.

What is the most common cause of Leber congenital amaurosis?

  1. Mutations in the RPE65 gene

  2. Mutations in the CEP290 gene

  3. Mutations in the AIPL1 gene

  4. Mutations in the GUCY2D gene


Correct Option: A
Explanation:

Mutations in the RPE65 gene are the most common cause of Leber congenital amaurosis. This gene is responsible for producing a protein that is essential for the function of the retinal pigment epithelium (RPE), a layer of cells that supports the retina.

Which retinal disorder is characterized by the accumulation of drusen, small yellow deposits, in the macula?

  1. Age-related macular degeneration

  2. Diabetic retinopathy

  3. Retinal detachment

  4. Glaucoma


Correct Option: A
Explanation:

Age-related macular degeneration is characterized by the accumulation of drusen in the macula, the central part of the retina responsible for sharp central vision.
