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:
Patient fixation: The patient fixates on a central point.
Stimulus presentation: A stimulus (e.g., a small object or light) is moved along the tangent screen.
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:
Detect visual field defects: Identify defects in the central and paracentral visual field.
Monitor glaucoma: Track changes in the visual field associated with glaucoma.
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.
Glaucoma significantly impacts the quality of life for those affected. Studies have shown that people with glaucoma experience ¹ ²:
Reduced Mobility: 60% of participants in one study couldn’t drive due to glaucoma-related vision loss, while others reported difficulty noticing things while walking or sitting in one place.
Emotional Distress: The psychosocial impact of glaucoma can lead to feelings of dependency and being a burden on family members, greatly affecting mental health.
Daily Activity Limitations: Patients experience difficulty reading, recognizing faces, and performing daily tasks due to progressive vision loss.
Poor General and Vision-Related Quality of Life: Monocular glaucoma patients have lower overall quality of life scores, with depression being a common comorbidity.
Financial Burden: Glaucoma patients, especially those in middle to low-income countries, may experience reduced monthly earnings due to limited mobility and job opportunities.
Factors Affecting Quality of Life:
Visual Acuity: The severity of vision loss directly impacts quality of life.
Female Gender: Women may experience a greater impact on their quality of life due to glaucoma.
Treatment Regimens: Surgical treatment and number of topical medications can negatively impact vision-related quality of life ² ³ ⁴.
Support and Resources:
Social welfare and psycho-social institutions can provide essential support for glaucoma patients.
Access to proper medical care, rehabilitation services, and counseling can help mitigate the impact of glaucoma on quality of life ¹.
