Purpose: To determine the corneal and retinal changes associated with serum calcium, phosphorus and parathyroid hormone (PTH) levels in patients with hypoparathyroidism.Methods: Patients who were under follow-up for hypoparathyroidism in the endocrinology department were included in the study. All participants underwent a complete ophthalmological examination. Moreover, central corneal thickness (CCT), anterior chamber depth (ACD), retinal nerve fiber layer (RNFL) thickness, ganglion cell layer (GCL) thickness were recorded. Serum biochemical parameters were recorded.Results: In a total of 75 patients (35 in the hypoparathyroidism group and 40 in the healthy control group) were included in this study. Central corneal thickness (519.95 ± 33.21 vs. 539.10 ± 32.96, p: 0.001) and RNFL (105.10 ± 11.89 vs. 113.56 ± 9.54, p: 0.005) were significantly thinner and ACD was significantly deeper in the hypoparathyroidism group.Conclusion: We determined thinner CCT and RNFL values in patients with hypoparathyroidism related to serum calcium levels together with a significant deepness in ACD.
