Terrien marginal degeneration is a noninflammatory, unilateral or asymmetrically bilateral, slowly progressive thinning of the peripheral corneal stroma.[1][2]

Sign and symptoms

The clinical presentation of Terrien's marginal degeneration is consistent with progressive blurred vision.[3]

Cause

The cause of Terrien marginal degeneration is unknown, its prevalence is roughly equal between males and females, and it usually occurs in the second or third decade of life.[2]

Diagnosis

The diagnosis for this ocular condition is done via corneal topography ( photokeratoscopy or videokeratography)[3]

Treatments

Spectacles or RGP contact lenses can be used to manage the astigmatism. when the condition worsens, surgical correction may be required.[4]
