What Is a Visual Field Defect?
Defect of visual field refers to the damaged visual field. The field of vision is that the eyeballs do not move, look forward a little, and the range of space you can see is the vision beyond the fovea. Treatment should find the primary disease causing the visual field defect and treat the cause.
Basic Information

- Visiting department

- Retinal detachment, glaucoma, retinal vein occlusion, retinal pigment degeneration, and brain tumors, cerebrovascular diseases, etc.
- Common symptoms
- Incomplete vision
Causes of visual field defects and common diseases
- Retinal detachment, glaucoma, retinal vein occlusion, retinal pigment degeneration, and brain tumors or cerebrovascular disorders are the more common causes of visual field defects. Most of them are caused by diseases of nearby tissues, among which tumor compression is the most common.
Differential diagnosis of visual field defect
- Glaucoma
- The most significant feature of glaucoma's visual field defect is the tubular visual field. The appearance of the tubular visual field has shown that glaucoma is very serious, and the visual field defect of glaucoma is irreversible.
- 2. White visual field defect
- The retina separates from its own pigment epithelium. The fundus features cyan-blue corrugated spherical bulges, dark red blood vessels undulating with ripples and round red fissures, and white visual field defects are the main features. More common in high myopia and elderly patients, is a serious eye disease. Early and timely treatment can control its development.
- 3. Blue visual field defect
- If the color-controlling tissue in the eye is abnormal, a visual field defect such as a blue visual field defect may occur.
Visual field defect examination
- The visual field test is to measure the visual function of each eye at a specific point in the visual range. Examining different light sensitivities at different points on the retina to determine deviations from normal sensitivity, eye diseases can cause general or local loss of visual acuity in the visual field. Visual field examination is to detect these early and follow up closely. The inspection uses an automatic perimeter, and you can also choose the blue-yellow light field test mode.
Visual field defect treatment principles
- Find the primary disease causing the visual field defect and treat the cause.
