Duration of hypoparathyroidism and serum parathyroid hormone (PTH), calcium and phosphorus levels were recorded. Results: This study included 46 female patients with postoperative hypoparathyroidism and 61 healthy female participants. There were no significant differences between the pupil diameters at different light intensities between the study groups (p>0.05 for all). Among the dynamic pupillometric measurements, pupil contraction amplitude was significantly higher in patients with postoperative hy- poparathyroidism when compared to that of healthy controls (1.85±0.04 mm vs 1.72±0.03 mm respectively, p=0.018). There was no significant correlation between the duration of hypoparathy- roidism, serum calcium, phosphorus, and PTH levels with static and dynamic pupillometry values (p>0.05 for all), with an exception of a positive correlation between the serum calcium level and amplitude of contraction (r=0.322, p=0.029). Conclusion: Pupil diameters at different light intensities were not affected in patients with postoper- ative hypoparathyroidism, but pupil contraction amplitude was higher than in healthy individuals.eninfo:eu-repo/semantics/openAccessEndokrinoloji ve MetabolizmaKlinik NörolojiNörolojik BilimlerOdyoloji ve Konuşma-Dil PatolojisiPhosphorusCalciumhypoparathyroidismparathyroid hormonepupil disordersArticle322677310.5336/ophthal.2022-915081261503
