The effects of unilateral forced nostril breathing on the intraocular pressures of right and left eyes was studied in 24 male and 26 female right-handed adults. In men, the forced breathing through both the right and left nostrils significantly decreased the intraocular pressures of both right and left eyes. For women, the forced breathing through right nostril did not affect the intraocular pressures of right and left eyes, and the forced breathing through left nostril also had no effect on the intraocular pressure of right eye, although it decreased the intraocular pressure of left eye significantly. These results show that unilateral forced nostril breathing decreases intraocular pressure especially in men, perhaps increasing sympathetic nervous system activity.

High intraocular pressure (HIOP) and high glucose levels are associated with oxidative stress. Although physical exercise protects against oxidative damage, its specific impact on eye health remains unclear. Thus, this study aimed to assess the impact of physical exercise on the oxidative status of whole eyes in male Swiss mice subjected to HIOP model and cafeteria diet (CD).

Intraocular pressure (IOP) is regulated through the balance of production and drainage of aqueous humor. The main route of aqueous-humor outflow comprises the trabecular meshwork (TM) and Schlemm's canal (SC). We reported that IL-6 trans-signaling can inhibit TGF-β signaling in TM cells and may affect regulation of IOP.

Purpose: To analyze patients with optic disc drusen (ODD), with emphasis on modern diagnostics.
Materials And Methods: Research of the literature was conducted, together with a retrospective statistical analysis of patients with ODD. The group included individuals with ODD diagnosed using at least one of the following (ultrasound - USG, optical coherence tomography - OCT, fundus autofluorescence - FAF).

Retrobulbar hematoma (RH) is a diagnostic and therapeutic emergency that may cause permanent vision loss. Lateral canthotomy and cantholysis (LCC) is typically performed when IOP is elevated or vision is compromised. The authors describe the outcomes of the largest cohort of patients with RH to date.

Purpose: Compare cup-to-disc ratio (CDR) measured by clinical assessment and optical coherence tomography (OCT) in pediatric eyes being monitored as glaucoma suspects for suspicious optic disc appearance.
Design: Retrospective cross-sectional study.
Methods: An institutional study following 221 eyes from 122 unique pediatric glaucoma suspects being monitored due to increased or asymmetric appearance of CDR.
