Purpose
To describe progressive corneal flattening in 4 patients with a diagnosis of bilateral keratoconus using Scheimpflug imaging. No contact lens, corneal collagen crosslinking nor other treatment was performed.
Setting
National Ophtalmology Centre named after acad. Zarifa Aliyeva.
Methods
Retrospective cases series study of 4 patients with previous diagnosis of keratoconus evaluated from 2019 to 2025. The following variables were evaluated: Maximum keratometry, anterior flattest, steeper keratometry, posterior elevation at the TP, central corneal thicknes, pachymetry at the thinnest point, distance from the thinnest point to the corneal center.
Results
Mean change in maximum keratometry was -3.1 diopters (D) , -2.7 D, -1.5 D and -2 D in patiens 1, 2, 3 and 4 respectively. Mean change in steeper keratometry was 0.7 D , 0.1 D, -0.1 D and 0.2 D in patiens 1, 2, 3 and 4 respectively. Mean change in CCT was -21 µm , 29 µm , -10 µm and 9 µm in patiens 1, 2, 3 and 4 respectively. Mean change in posterior elevation was -14 µm , -2 µm , 2 µm and 5 µm in patiens 1, 2, 3 and 4 respectively.
Conclusions
A natural regression of Keratoconus was observed in this 4 patients without any treatment. FINANCIAL DISCLOSURE: None
