OBJECTIVE: To show the association between keratoconus and macular dystrophy.
MATERIAL AND METHOD: All patients with macular dystrophy and associated clinical findings leading to a diagnosis of keratoconus by corneal topography were retrospectively reviewed during a 10-year period. Uncorrected and best-corrected visual acuity, automated refraction, manifest refraction, corneal thickness, and corneal curvature by corneal topography were evaluated
RESULTS: Three patients with macular dystrophy exhibiting decreased vision, multifocal white dense deposits, and haze surrounding the deposits in the corneal stroma were evaluated. All had a steep corneal curvature of >47 diopters and a thin cornea consistent with keratoconus. Penetrating keratoplasty was performed in one patient with severely decreased vision. Macular dystrophy was diagnosed based on an Alcian blue-stained pathological specimen.
CONCLUSION: Keratoconus may develop as a result of changes associated with macular dystrophy. Therefore, patients with severely decreased vision should be evaluated for keratoconus to ensure proper management.
