[Terrien's corneal dystrophy]

In clinical and histomorphological case-history of a 27-year-old man the authors describe a rare corneal finding where Terrien's corneal dystrophy was confirmed. Correct evaluation of the clinical stage of the disease is considered important for the indication of microsurgical treatment. Light and electron microscopy made it possible to diagnose the dystrophic form of the disease and the clinical course confirmed the indication of surgical treatment.
