Objective: This study delves into the impact of three yoga poses, namely Adho Mukha Svanasana, Uttanasana, and Viparita Karani, on intraocular pressure (IOP) in 16 patients diagnosed with open-angle glaucoma and a control group of 16 healthy individuals. Material and Methods: The study design required all participants to perform the mentioned yoga poses sequentially. IOP measurements were collected four times during the execution of each pose: at the onset of the pose, after maintaining the pose for two minutes, immediately after ending the pose, and following a ten-minute rest period. Results: The data showed a statistically significant increase in IOP from baseline values after two minutes of performing each yoga pose in both patient and control groups. The most substantial increase was witnessed during the first yoga pose (Adho Mukha Svanasana), which showed a rise in IOP from 16.44±3.22 mmHg to 28.63±5.09 mmHg in glaucoma patients and 11.63±2.33 mmHg to 22.31±2.38 mmHg in the control group. Interestingly, there was no significant difference between the two groups concerning the magnitude of IOP increase across all the yoga poses. Conclusion: The findings suggest that certain yoga poses, especially those requiring the head to be downward-facing, lead to significant increases in IOP. However, these elevated IOP levels return to baseline as soon as the pose ends. More comprehensive, long-term follow-up studies are necessary to understand the potential consequences of these temporary IOP elevations in glaucoma patients. As a precautionary measure, glaucoma patients who practice or intend to start practicing yoga should disclose this information to their ophthalmologists.

Amaç: Bu çalışma, Adho Mukha Svanasana, Uttanasana ve Viparita Karani isimli üç yoga pozu üzerindeki intraoküler basınç (IOP) üzerindeki etkisini, açık açılı glokom tanısı konmuş 16 hasta ve 16 sağlıklı birey olmak üzere bir kontrol grubunda incelemektedir. Gereç ve Yöntemler: Çalışma tasarımı, tüm katılımcıların belirtilen yoga pozlarını sırasıyla gerçekleştirmesini gerektiriyordu. Her poz sırasında IOP ölçümleri dört kez toplandı: poz başlangıcında, pozun iki dakika sürdürülmesinin ardından, pozun hemen sona ermesinin ardından ve on dakikalık bir dinlenme süresinin ardından. Bulgular: Veriler, hem hasta hem de kontrol gruplarında her yoga pozunun iki dakika boyunca gerçekleştirilmesinden sonra, IOP'deki baz değerlerden istatistiksel olarak anlamlı bir artış gösterdi. En belirgin artış, glokom hastalarında IOP'un 16.44±3.22 mmHg'dan 28.63±5.09 mmHg'ya ve kontrol grubunda 11.63±2.33 mmHg'dan 22.31±2.38 mmHg'ya çıktığı ilk yoga pozu olan Adho Mukha Svanasana sırasında gözlendi. İlginç bir şekilde, iki grup arasında tüm yoga pozları boyunca IOP artışının büyüklüğü açısından anlamlı bir fark bulunmadı. Sonuç: Bulgular, başın aşağıda olmasını gerektiren belirli yoga pozlarının, IOP'de önemli artışlara yol açtığını öne sürmektedir. Ancak, bu yükseltilmiş IOP seviyeleri, poz sona erer ermez başlangıç değerlerine geri dönmektedir. Bu geçici IOP yükselmelerinin glokom hastalarında potansiyel sonuçlarını anlamak için daha kapsamlı, uzun dönemli takip çalışmaları gereklidir. Önlem olarak, yoga pratiği yapan veya yoga pratiği başlamayı planlayan glokom hastalarının, bu bilgiyi göz doktorlarına bildirmeleri önerilir.
