The visual field test, also known as campimetry, is a fundamental tool in the ophthalmological field that allows evaluating the width of an individual's visual field. This test plays a crucial role in the diagnosis and monitoring of various visual disorders, providing valuable information about eye health and the functioning of the visual system. Below, we explain the importance and applications of visual field testing in the medical context.

1. Diagnosis of glaucoma

One of the most common uses of visual field testing is in the diagnosis and monitoring of glaucoma, a progressive eye disease that affects the optic nerve and can lead to irreversible vision loss. Campimetry allows us to identify areas of peripheral visual loss, typical in the early stages of glaucoma, which enables early intervention to stop its progression.

2. Detection of visual defects

Visual field testing is also essential to identify visual defects, such as scotomas or areas of reduced vision. These defects may be indicative of various medical conditions, such as optic nerve injuries, neurological diseases, or retinal disorders. By diagnosing and quantifying these defects, eye care professionals can personalize treatments and improve the patient's quality of life.

3. Monitoring of degenerative diseases

Degenerative diseases such as retinopathy pigmentosa and macular degeneration can affect the visual field over time. Visual field testing is used to monitor the progression of these conditions, allowing adjustments to the treatment plan and providing essential information for long-term planning.

4. Evaluation of general visual function

In addition to its application in the diagnosis of specific conditions, campimetry is also used to evaluate general visual function. This includes detecting possible problems in the central and peripheral visual field, which may be indicative of various eye disorders.

In summary, visual field testing plays a crucial role in the diagnosis and monitoring of a variety of visual and neurological disorders. Its application ranges from the early detection of diseases such as glaucoma to the evaluation of general visual function. With constant advances in technology and understanding of vision, this test continues to be an indispensable tool to ensure eye health and quality of life for patients.
