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.
The Humphrey Field Analyzer (HFA) is the most widely used automated device for what type of perimetry?
FDT perimetry
Static perimetry
Kinetic perimetry
Manual perimetry
Which of the following is a significant advantage of the Humphrey Field Analyzer (HFA)?
It is inexpensive and highly portable.
It is ideal for patients with poor fixation.
It maps the extreme periphery better than Goldmann.
It provides quantitative, objective, and statistically analyzed results.
A disadvantage of the HFA is that it
Does not provide statistical analysis.
Is not standardized in clinical practice.
Is only suitable for screening, not diagnosis.
Can be time-consuming and requires patient cooperation.
A major advantage of FDT perimetry is its
Rapid test duration, suitable for screening.
Ability to track subtle progression over time.
High sensitivity for all types of visual field loss.
Comprehensive mapping of the entire visual field.
Compared to conventional perimetry, FDT perimetry is generally less affected by
The patient's age.
Patient cooperation.
The presence of scotomas.
Pupil size and refractive error.
Which of the following is a limitation of FDT perimetry?
It is very slow to perform.
It requires a large, expensive machine.
It cannot detect early glaucomatous damage.
It is less sensitive for non-glaucomatous field loss.
If a patient reports wavy lines and missing areas in their central vision, which test would be most appropriate for initial assessment?
Amsler Grid
Goldmann Perimetry
Bjerrum Tangent Screen
Humphrey Field Analyzer
Which instrument provides objective, reproducible, and statistically analyzed results, making it ideal for tracking glaucoma progression?
Amsler Grid
Goldmann Perimetry
Humphrey Field Analyzer
Bjerrum Tangent Screen
Which of the following statement is TRUE about Bjerrum Tangent Screen?
It can be used at home as self-monitoring.
It can be used to determine static perimetry.
It is an invasive procedure and difficult to standardize.
It is consisted of a flat, black surface screen to measure 30 degrees of visual field.
The Bjerrum tangent screen primarily assesses which portion of the visual field?
The central 30∘
Only the extreme peripheral 90∘
The entire 180∘ visual field
The superior half of the visual field
