Peripheral Vision Loss
Comprehensive guide to tunnel vision causes and treatment
What is Peripheral Vision Loss?
Peripheral vision loss, commonly referred to as tunnel vision, is a condition characterized by a narrowing of the visual field where the outer edges of what you can see become progressively restricted. While central vision may remain relatively clear, individuals with this condition experience a significant reduction in their side vision. This can dramatically impact daily activities such as walking, driving, and navigating unfamiliar environments. The condition typically results from damage to the optic nerve or retina and is often progressive if left untreated.
Healthy Baseline
Optimal function
- Full 180-degree horizontal visual field
- Ability to see objects at 90 degrees from central focus
- Normal night vision and low-light adaptation
- No blind spots or dark areas in peripheral field
- Smooth awareness of environment on all sides
- Good spatial awareness and depth perception

What's Causing Your Peripheral Vision Loss
Identifying the underlying causes of peripheral vision loss allows us to target treatment effectively for lasting results.
Primary Open-Angle Glaucoma
Most Common (40%)Gradual increase in intraocular pressure damages optic nerve fibers, typically affecting peripheral vision first.
Normal-Tension Glaucoma
Common (15%)Optic nerve damage despite normal eye pressure, possibly from poor blood flow.
Retinitis Pigmentosa
Genetic (10%)Inherited disorder causing progressive degeneration of retinal photoreceptor cells.
Stroke (Cerebrovascular Accident)
Common (15%)Brain damage from stroke can affect visual processing areas.
Pituitary Adenoma
Less CommonPituitary gland tumor compresses optic chiasm.
Retinal Detachment
Acute EmergencyOptic Neuropathy
Less CommonVarious causes including inflammation, ischemia, or toxicity damage optic nerve.
How We Assess Causes
Our comprehensive evaluation combines detailed health history, advanced diagnostic testing, and constitutional assessment to identify the unique combination of factors contributing to your peripheral vision loss.
Important Note
The probabilities shown are based on clinical research and our patient population. Your individual case may have different contributing factors. A comprehensive evaluation is necessary to determine your specific root causes.
