I. Kremer et al., HISTOLOGIC EVIDENCE OF RECURRENT KERATOCONUS 7 YEARS AFTER KERATOPLASTY, American journal of ophthalmology, 119(4), 1995, pp. 511-512
PURPOSE/METHODS: A 42-year-old patient with keratoconus developed clin
ical signs of recurrent keratoconus in her right corneal graft seven y
ears after the first keratoplasty was performed. She underwent success
ful corneal regrafting. RESULTS/CONCLUSIONS: The histopathologic exami
nation of the corneal burton disclosed typical findings of keratoconus
, including breaks in Bowman's layer filled with connective tissue or
epithelium. These histologic findings in the corneal graft support our
clinical diagnosis of keratoconus. However, the pathogenesis of this
complication is still not clear and further research is needed.
