Effect of Shakthi bandha asana on Pupillary Light Reflex in Polycystic Ovarian Syndrome: A Case Study

This case report explores the novel use of Shakthi bandha asana to address autonomic dysfunction in a young woman diagnosed with polycystic ovarian syndrome (PCOS), providing insights into the potential benefits of yoga on neurological function. A 22-year-old woman presented with irregular menstrual cycles, significant weight gain, acne, oily skin, and chronic fatigue, exhibited prolonged menstrual intervals and abdominal cramping, with obesity confirmed by body mass index. PCOS was previously diagnosed. She underwent an 8-week supervised Shakthi bandha asana program. Postintervention assessments showed notable improvements in pupillary light reflex parameters, reflex latency (170 ms to 230 ms), and minimum pupil diameter (2.8 mm to 3.2 mm). Absolute constriction amplitude (1.8 mm to 2.4 mm), and duration of constriction (620 ms to 910 ms), indicating enhanced parasympathetic activity. While recovered, pupil diameter (4.9 mm to 3.1 mm), Duration of redilation duration of dilation (2100 ms to 1600 ms), and absolute dilation amplitude (2.1 mm to 1.6 mm) and maximum redilation velocity (4.4 mm/s to 3.1 mm/s), reflecting a potential shift in autonomic balance. The yoga regimen resulted in enhanced autonomic responsiveness and improved neurological markers, reflected in pupillary light reflex changes and overall well-being. Targeted yoga practice, such as Shakthi bandha asana , may serve as a holistic adjunct therapy for PCOS, promoting both hormonal balance and autonomic health.
