THE BJERRUM TANGENT SCREEN

The Bjerrum tangent screen is a device used in ophthalmology to assess the visual field, particularly the central and paracentral areas. It’s a flat surface with a tangent curve marked on it, used to map out the field of vision.

How it’s used:

  1. Patient fixation: The patient fixates on a central point.
  2. Stimulus presentation: A stimulus (e.g., a small object or light) is moved along the tangent screen.
  3. Visual field mapping: The patient indicates when they see the stimulus, allowing the examiner to map out the visual field.

Purpose:

The Bjerrum tangent screen is used to:

  1. Detect visual field defects: Identify defects in the central and paracentral visual field.
  2. Monitor glaucoma: Track changes in the visual field associated with glaucoma.
  3. Assess optic nerve function: Evaluate the function of the optic nerve.

The Bjerrum tangent screen is a useful tool for assessing and monitoring visual field defects, particularly in glaucoma patients.

VISUAL FIELD ANALYSER

A Visual Field Analyzer is a medical device used to assess the sensitivity and coverage of a patient’s visual field. It maps out the field of vision, detecting any defects or abnormalities, particularly in peripheral vision.

Key Features:

  • Visual Field Testing: Measures the sensitivity of the retina in different locations.
  • Diagnostic Capabilities: Detects conditions like glaucoma, age-related macular degeneration, and other neurological disorders.
  • Variety of Tests: Offers different testing strategies, such as threshold and screening tests.

Types of Visual Field Analyzers:

  • Humphrey Field Analyzer 3 (HFA 3): Considered the gold standard, featuring Guided Progression Analysis and SITA Faster testing.
  • ObjectiveFIELD Analyzer: Uses multifocal pupillographic objective perimetry (mfPOP) for completely objective visual field assessment.
  • PalmScan VF2000: A wearable, portable analyzer with gaze tracking and customizable reports.
  • Easyfield VR: Utilizes virtual reality technology for visual field screenings and threshold exams.
  • Kowa AP-7000: Offers advanced diagnostic capabilities and high accuracy ¹ ² ³ ⁴.

Benefits:

  • Early Detection: Identifies visual field defects and conditions at an early stage.
  • Accurate Results: Provides reliable and reproducible results.
  • Patient Comfort: Some devices offer features like automated verbal instructions and gaze tracking for improved patient experience.

When selecting a Visual Field Analyzer, consider factors such as ⁵:

  • Measurement Accuracy: Look for devices with high accuracy and reliability.
  • Testing Strategies: Choose a device that offers a range of testing options.
  • Patient Comfort: Consider devices with features that improve patient experience.
  • Data Management: Ensure the device allows for easy data storage and analysis.
