BackgroundThe association between ocular hypertension and endogenous hypercortisolemia, as well as the ophthalmological outcomes after endocrine remission due to a surgical resection were still unknown. MethodsIntraocular pressure (IOP), visual field and peripapillary retinal nerve fiber layer thickness were documented in all patients with Cushing’s disease (CD) admitted to a tertiary pituitary center for surgery from Jan to Jul 2019. Patients with acromegaly and patients with nonfunctioning pituitary adenoma (NFPA) during the same study period were served as controls. We calculated the odds ratio and identified risk factors of developing ocular hypertension, and presented postoperative trends of IOP.Results52 patients (38.4±12.4 years old) with CD were included. IOP was higher in patients with CD (left 19.4 ± 5.4 mmHg and right 20.0 ± 7.1 mmHg) than patients with acromegaly (left 17.5 ± 2.3 mmHg and right 18.6 ± 7.0 mmHg, p = 0.033) and patients with NFPA (left 17.8 ± 2.6 mmHg and right 17.4 ± 2.4 mmHg, p = 0.005). 21 eyes (20.2%) in patients with CD were diagnosed with ocular hypertension comparing to 4 eyes (4.7%) in the acromegaly group and 4 eyes (4.5%) in the NFPA group. The odds ratio of developing ocular hypertension in patients with CD was 5.1 (95% CI, 1.3 – 25.1, p = 0.029) and 6.6 (95% CI, 1.8 – 30.3, p = 0.007), comparing with the two control groups, respectively. Among patients with CD, those with higher urine free cortisol were more likely to develop ocular hypertension (OR 19.4, 95% CI 1.7 – 72.6). IOP decreased at one-month follow-up in patients with CD and the change sustained at three-month follow-up. ConclusionsIn conclusion, patients with CD had increased risk of developing ocular hypertension comparing to other types of pituitary adenomas, which warrant the discretion of both ophthalmologists and neuroendocrinologists.
