Iris atrophy refers to thinning or degeneration of the iris tissue. The iris loses some of its structure, creating gaps or irregular edges. People may notice changes in pupil shape or increased light sensitivity. This condition often appears with aging but can also develop from inflammation or high pressure. Exams help determine how much tissue has weakened.
read more about iris atrophy ...Aging is a common factor as iris fibers naturally thin over time. Long-standing high pressure can damage the tissue. Inflammation may break down iris fibers. Trauma or prior surgery can also cause localized atrophy. Each cause produces a different pattern of thinning.
Light sensitivity increases as the iris loses its ability to control incoming light. The pupil may appear irregular or show small holes. Some people notice reduced contrast or mild glare. Vision usually stays stable unless the underlying condition progresses. Symptoms vary by severity and location of thinning.
Slit lamp exam shows areas of thinning or loss of pigment. Doctors check pupil reaction and overall iris structure. Pressure measurements help identify glaucoma-related changes. Imaging can document the degree of atrophy. Diagnosis guides long-term monitoring.
Treatment focuses on the underlying cause. Pressure control helps slow further damage when glaucoma is present. Anti-inflammatory therapy may help if atrophy stems from uveitis. Protective eyewear reduces glare and discomfort. Regular checkups track progression and overall eye health.
Mostly through increased glare or light sensitivity.
Yes, depending on the cause.
Yes. It may be unilateral or bilateral.
Seek care if new glare or pupil changes appear.
