What is the most common cause of vitreous hemorrhage?

  1. Diabetic retinopathy

  2. Retinal tear

  3. Posterior vitreous detachment

  4. Age-related macular degeneration


Correct Option: C
Explanation:

Posterior vitreous detachment is the most common cause of vitreous hemorrhage, occurring when the vitreous humor separates from the retina.

Which of the following is a symptom of macular degeneration?

  1. Blurred vision

  2. Flashes of light

  3. Floaters

  4. All of the above


Correct Option: D
Explanation:

Blurred vision, flashes of light, and floaters are all symptoms of macular degeneration, which affects the central part of the retina.

What is the leading cause of retinal detachment?

  1. Lattice degeneration

  2. Myopia

  3. Trauma

  4. Age-related macular degeneration


Correct Option: A
Explanation:

Lattice degeneration is the leading cause of retinal detachment, a condition in which the retina separates from the underlying choroid.

Which of the following is a treatment option for diabetic retinopathy?

  1. Laser photocoagulation

  2. Anti-VEGF injections

  3. Vitrectomy

  4. All of the above


Correct Option: D
Explanation:

Laser photocoagulation, anti-VEGF injections, and vitrectomy are all treatment options for diabetic retinopathy, depending on the stage and severity of the condition.

What is the primary function of the vitreous humor?

  1. Providing structural support to the eye

  2. Transmitting light to the retina

  3. Nourishing the retina

  4. All of the above


Correct Option: D
Explanation:

The vitreous humor performs multiple functions, including providing structural support, transmitting light, and nourishing the retina.

Which of the following is a risk factor for epiretinal membrane?

  1. Diabetes

  2. Hypertension

  3. Posterior vitreous detachment

  4. All of the above


Correct Option: C
Explanation:

Posterior vitreous detachment is a risk factor for epiretinal membrane, a condition in which a thin membrane forms on the surface of the retina.

What is the most common type of macular hole?

  1. Idiopathic macular hole

  2. Traumatic macular hole

  3. Myopic macular hole

  4. All of the above


Correct Option: A
Explanation:

Idiopathic macular hole is the most common type, occurring spontaneously without any apparent cause.

Which of the following is a symptom of vitreomacular traction syndrome?

  1. Metamorphopsia

  2. Micropsia

  3. Macular pucker

  4. All of the above


Correct Option: D
Explanation:

Metamorphopsia, micropsia, and macular pucker are all symptoms of vitreomacular traction syndrome, a condition caused by abnormal traction on the macula.

What is the primary treatment for proliferative diabetic retinopathy?

  1. Laser photocoagulation

  2. Anti-VEGF injections

  3. Vitrectomy

  4. All of the above


Correct Option: D
Explanation:

Laser photocoagulation, anti-VEGF injections, and vitrectomy are all treatment options for proliferative diabetic retinopathy, depending on the stage and severity of the condition.

Which of the following is a risk factor for central serous chorioretinopathy?

  1. Type A personality

  2. Use of corticosteroids

  3. Pregnancy

  4. All of the above


Correct Option: D
Explanation:

Type A personality, use of corticosteroids, and pregnancy are all risk factors for central serous chorioretinopathy, a condition characterized by fluid accumulation beneath the retina.

What is the most common cause of choroidal neovascularization?

  1. Age-related macular degeneration

  2. Myopia

  3. Trauma

  4. All of the above


Correct Option: A
Explanation:

Age-related macular degeneration is the most common cause of choroidal neovascularization, a condition in which new blood vessels grow beneath the retina.

Which of the following is a symptom of retinal vein occlusion?

  1. Sudden loss of vision

  2. Blurred vision

  3. Floaters

  4. All of the above


Correct Option: D
Explanation:

Sudden loss of vision, blurred vision, and floaters are all symptoms of retinal vein occlusion, a condition caused by blockage of a retinal vein.

What is the primary treatment for macular edema?

  1. Laser photocoagulation

  2. Anti-VEGF injections

  3. Vitrectomy

  4. All of the above


Correct Option: D
Explanation:

Laser photocoagulation, anti-VEGF injections, and vitrectomy are all treatment options for macular edema, depending on the underlying cause and severity of the condition.

Which of the following is a risk factor for lattice degeneration?

  1. Myopia

  2. Family history

  3. Age-related macular degeneration

  4. All of the above


Correct Option: D
Explanation:

Myopia, family history, and age-related macular degeneration are all risk factors for lattice degeneration, a condition characterized by lattice-like lines in the retina.

What is the most common cause of vitreous floaters?

  1. Posterior vitreous detachment

  2. Retinal tear

  3. Age-related macular degeneration

  4. All of the above


Correct Option: A
Explanation:

Posterior vitreous detachment is the most common cause of vitreous floaters, which are small particles that appear to float in front of the eyes.
