  1. Autorefraction

  2. Corneal Topography

  3. Pachymetry

  4. Retinal Nerve Fiber Layer (RNFL) Analysis


Correct Option: B
Explanation:

Corneal Topography is a non-invasive imaging technique that maps the shape, thickness, and curvature of the cornea, providing valuable information for diagnosing and managing corneal conditions such as keratoconus and astigmatism.

What is the primary function of a Slit Lamp Examination in ophthalmic imaging?

  1. Measuring intraocular pressure (IOP)

  2. Visualizing the anterior segment of the eye in detail

  3. Evaluating retinal blood flow and leakage

  4. Assessing the optic nerve and surrounding structures


Correct Option: B
Explanation:

Slit Lamp Examination is a non-invasive imaging technique that allows detailed visualization of the anterior segment of the eye, including the cornea, iris, lens, and anterior chamber, enabling the detection of various eye conditions and abnormalities.

Which imaging modality is commonly used to measure intraocular pressure (IOP) in ophthalmic practice?

  1. Autorefraction

  2. Tonometry

  3. Ophthalmoscopy

  4. Visual Field Analysis


Correct Option: B
Explanation:

Tonometry is a non-invasive imaging technique used to measure intraocular pressure (IOP), which is crucial for diagnosing and managing conditions such as glaucoma and ocular hypertension.

What is the primary purpose of Autorefraction in ophthalmic imaging?

  1. Evaluating retinal blood flow and leakage

  2. Measuring corneal thickness and curvature

  3. Assessing the angle between the iris and cornea

  4. Determining the refractive error of the eye


Correct Option: D
Explanation:

Autorefraction is a non-invasive imaging technique that objectively measures the refractive error of the eye, including nearsightedness (myopia), farsightedness (hyperopia), and astigmatism, aiding in the prescription of corrective lenses.

Which imaging modality is specifically designed to assess the optic nerve and surrounding structures in detail?
