Abstract

Objectives: Noninvasive monitorization of retinal structures of the eye could be a predictor for systemic microvasculature dysfunction in transplant recipients. In this study, our purpose was to determine the optic disc and peripapillary microvascular changes in pediatric patients who had undergone liver or renal transplant surgery. Materials and Methods: The study was performed at Baskent University. The medical records were reviewed, and patients who had liver or renal transplant in the last 10 years and were between 4 and 18 years old were included in the study. The optic disc and peripapillary vascular density parameters were obtained by optical coherence tomography angiography (Avanti RTVue XR). The results were compared with the results from age-matched, sex-matched, and spherical equivalent-matched healthy subjects. Results: Our study included 32 eyes of 16 liver transplant patients, 20 eyes of 10 renal transplant patients, and 64 eyes of 32 healthy participants (control). Whole image peripapillary, inside disc, peripapillary, superior and inferior hemisphere, and superior, inferior, temporal, and nasal quadrant peripapillary vascular densities were evaluated. No statistically significant differences in any parameter were noted between the healthy control group and the patient groups (P > .05 for all parameters). Conclusions: Peripapillary vascular density measurements were not affected in pediatric renal and liver transplant patients.
