Resumen

Objetivo. Determinar y comparar el grosor de la coroides (CT) en pacientes con queratocono (KC) usando OCT con Enhanced Depth Imaging (EDI). Métodos. Estudio comparativo transversal que incluye 26 pacientes con KC y 26 controles sanos evaluados con Pentacam y EDI-OCT. El KC fue medido manualmente con la función Caliper en trece puntos a intervalos regulares de 500 µm. Resultados. El promedio de CT en T6 fue de 253,96 ± 88,95 μm en el grupo KC, y de 309,39 ± 94,11 μm en el grupo de control (p <0,041). No se observaron diferencias significativas en la media de CT en el resto de los puntos, incluyendo el CT subfoveal (M), 351.48 ± 106.3 vs 365.35 ± 114.6 μm, (p = 0.66). No se observó ninguna correlación entre la media de CT (M) subfoveal, la media de CT en el grupo KC, y los valores de K1 (p = 0,977 y p = 0,498 respectivamente), K2 (p = 0,450 y p = 0,656), la asfericidad corneal (Q) (p = 0,986 y p = 0. 902), paquimetría mínima (Pachy) (p = 0,408 y p = 0,688), índice de queratocono (KI) (p = 0,601 y p = 0,217), índice de asimetría vertical (VIA) (p = 0,296 y p = 0,523), estadificación del KC (TKC) (p = 0,549 y p = 0,08) y morfología del ápice corneal. Conclusión. Se observó un CT significativamente menor en el grupo KC en T6 (3000 μm temporal a la fóvea). No se encontraron diferencias significativas entre los valores del CT en los pacientes con KC y en los sujetos sanos en los 12 puntos de medida restantes. No se encontró ninguna asociación entre los índices refractivos y queratométricos obtenidos por la topografía corneal y el CT subfoveal.
