Objective: To report the concomitant presentation of keratoconus and macular corneal dystrophy in two cases.
Methods: Two siblings with concomitant keratoconus and macular corneal dystrophy are presented. Complete ophthalmologic examination and computerized videokeratography were performed in both patients. Case 1 underwent penetrating keratoplasty in both eyes sequentially; histopathologic examination of excised corneal buttons with special stains was performed. Case 2 was observed.
Results: Both patients manifested typical signs and topographic evidence of keratoconus associated with macular dystrophy. Histopathologic studies in case 1 confirmed the same clinical diagnosis.
Conclusion: To our knowledge, this is the first report of such a concurrence in the English literature and could lead to further studies on the possible pathophysiologic or genetic link between these 2 entities.
