Abstract: Purpose: This study examines the impact of different yoga asanas and pranayama practices on intraocular pressure (IOP) and tear film stability. This research aims to assess the ocular health advantages of yoga by examining physiological factors related to eye pressure control and tear film stability. Methods: A cross-sectional study was performed on 40 persons aged 20 to 40 who consistently engaged in yoga practice. The participants completed pre- and post-exercise evaluations utilizing the Non-Contact Tonometer to determine intraocular pressure (IOP) and employed both the Tear Break-Up Test (TBUT) to analyze tear film stability. The yoga practice spanned 40-50 minutes and comprised asanas including Surya Namaskar, Tadasana, Vriksasana, Trikonasana, and Bhujangasana, along with breathing techniques such as Bhramari Pranayama, Anulom-Vilom, and Kapalbhati. The data analysis was to evaluate yoga's effect on ocular metrics. Results: Surya Namaskar markedly affected intraocular pressure and tear film stability, demonstrating a statistically significant difference relative to other yoga asanas. Tadasana, Vriksasana, Bhujangasana, and Virabhadrasana demonstrated minimal impact on intraocular pressure (IOP), whereas Kapalbhati resulted in a temporary elevation in IOP due to vigorous exhalation. Pranayama techniques, including Anulom-Vilom and Nadi Sodhan, exhibited a progressive reduction in intraocular pressure over time. Most yoga poses did not substantially affect tear film integrity, except Surya Namaskar, which showed a considerable influence. Conclusion: The research emphasizes Surya Namaskar as a potentially advantageous yoga practice for affecting intraocular pressure and tear film stability. Other yoga asanas have shown negligible effects, however, pranayama approaches demonstrated potential for long-term intraocular pressure stability. Additional research with expanded sample size is advised to corroborate these findings and investigate the therapeutic ramifications of yoga on eye health.
