Intraepithelial corneal infiltrates are small clusters of inflammatory cells located within the surface layers of the cornea. They appear as tiny white or gray spots and often form after viral illness, surface inflammation, or immune reactions. These infiltrates can cause discomfort and temporary vision changes. Exam findings guide treatment based on severity and cause.

Some immune responses create superficial infiltrates without infection. Chronic rubbing may worsen inflammation. Identifying the pattern helps distinguish infectious from non-infectious causes.
People may feel irritation or foreign-body sensation. Light sensitivity rises when the surface becomes inflamed. Vision may fluctuate if infiltrates scatter light. Redness and tearing often accompany active inflammation. Symptoms vary depending on infiltrate size and location.
A slit lamp exam reveals the depth and distribution of infiltrates. Surface staining helps detect associated epithelial defects. History clarifies whether infection or irritation is more likely. Imaging is rarely needed unless deeper involvement is suspected. Diagnosis relies on appearance and context.
Treatment depends on the cause. Viral cases often improve with supportive care. Immune-related infiltrates respond to topical anti-inflammatory medication. Avoiding triggers such as lens overwear helps prevent recurrence. Follow-up checks ensure that infiltrates fade and the surface heals.
Only when caused by viral infection.
Yes. They can scatter light and blur vision temporarily.
Contacts should be avoided until the surface recovers.
Seek care if irritation worsens or vision drops suddenly.
