Purpose: To determine the frequency and describe the histopathologic features of stromal corneal dystrophies over a 10-year period.Methods: A single-centered, retrospective analysis was performed on corneal specimens diagnosed as stromal dystrophies retrieved from the Henry C. Witelson Ophthalmic Pathology Laboratory and Registry (Montreal, Canada) over a period of 10 years. Corneal specimens obtained during keratoplasty were subjected to hematoxylin and eosin, periodic acid-Schiff, and other special staining.Results: During the period of the study, 885 corneal specimens from penetrating keratoplasties were received. Twenty-six (2.9%) specimens from a total of 22 patients showed stromal corneal dystrophies: 17 (65.4%) eyes with lattice dystrophy, 5 (19.2%) eyes with combined granular/lattice (Avellino) dystrophy, 3 (11.5%) eyes with granular dystrophy, and 1 (3.9%) eye with macular dystrophy.Conclusions: Corneal stromal dystrophies have distinct histopathologic features, which can be diagnosed with routine and special staining, particularly for combined granular/lattice (Avellino) dystrophy. Clinically, combined granular/lattice (Avellino) dystrophy can have features of both lattice and granular dystrophies, which can be misleading for diagnosis. Lattice dystrophy was the most frequent stromal dystrophy in this particular population.
