Visual Field Evaluation Instrument

Which visual field test is described as a quick, qualitative, and gross screening method?

• Goldmann Perimetry

• Humphrey Field Analyzer (HFA)

• Confrontation Visual Field Test

• Frequency Doubling Technology (FDT)

What is a primary advantage of the Confrontation Visual Field Test?

• It can detect subtle visual field defects.

• It provides a permanent record of the field.

• It provides quantitative, precise measurements.

• It is can be done anywhere and requires no equipment.

A major limitation of the Confrontation Visual Field Test is that it:

• Is time-consuming to perform.

• Is only suitable for central vision assessment.

• Requires specialized and expensive equipment.

• Is highly subjective and cannot detect subtle defects.

The Amsler grid is primarily used to detect abnormalities in which part of the visual field?

• The far periphery

• The central 10-20 degrees

• The superior nasal quadrant

• The inferior temporal quadrant

Which term describes the distortion of straight lines, often detected with an Amsler grid?

• Scotoma

• Diplopia

• Metamorphopsia

• Photophobia

A key advantage of the Amsler grid is its ability to:

• Quantify the depth of visual field loss.

• Detect peripheral visual field defects.

• Provide an objective, reproducible record.

• Be used for patient self-monitoring at home.

Goldmann perimetry is classified as

• Static perimetry

• Kinetic perimetry

• Automated perimetry

• Frequency doubling perimetry

What are "isopters" in Goldmann perimetry?

• The light stimuli used in the test.

• Points where the patient fixates.

• The blind spots mapped by the machine.

• Lines connecting points of equal visual sensitivity.

A significant advantage of Goldmann perimetry is its ability to

• Be less dependent on examiner skill.

• Provide statistical analysis of results.

• Be performed quickly and automatically.

• Map the entire visual field, including the far periphery.

What is a major disadvantage of Goldmann perimetry?

• It is compact and portable.

• It is highly automated and objective.

• It cannot be used for patients with significant field loss.

• It is time-consuming and requires a highly skilled examiner.
