Posterior Pole retinal thickness distribution pattern in keratoconus
International Ophthalmology, 2020Co-Authors: Ali Mahdavi Fard, Sangita P Patel, Raana Sorkhabi, Sara Salekzamani, Elena Pezzino, Nader D NaderAbstract:PURPOSE To evaluate the pattern of retinal thickness distribution in patients with keratoconus (KCN) and its correlation with disease severity. METHODS For this cross-sectional cohort study, the study subjects with documented keratoconus and normal eyes were prospectively enrolled. All subjects had anterior segment (Pentacam HR) and Posterior segment (Spectralis) imaging. Posterior segment imaging by optical coherence tomography included the Posterior Pole asymmetry analysis map. Data were analyzed with multiple linear regression models and correlation tests to examine the mean and variance of the measured thickness of the retina and its distribution relative to the presence and severity of KCN. RESULTS A total of 24 subjects with keratoconus (48 eyes) and 14 normal subjects (28 eyes) enrolled in this study. The Posterior Pole retinal thickness, both superior and inferior hemifields, as well as the overall retinal thickness in KCN patients was greater than the control group. There was a direct correlation between the overall retinal thickness of the Posterior Pole and the severity of KCN (R2 = 0.422, P < 0.001). However, the variability of the retinal thickness showed no difference between KCN-afflicted and healthy eyes. CONCLUSION Although KCN is a disease of the anterior segment of the eye, we found an orderly increase in Posterior Pole retinal thickness that is correlated with the severity of disease in KCN eyes compared to control. These findings suggest that the retina may maintain some degree of plasticity to respond to the degraded optical system of the eye.
