Episode #14 -Branch Retinal Vein Occlusion — Why Managing Retinal Circulation Is Important

Ayurveda and Eye Treatment is a podcast on the specialty of Eye treatment in Ayurveda. The podcast aims to give insights about treatment of eye diseases in Ayurveda. In this episode, Dr. P.K. Santhakumari, Chief Physician at Matha Ayurveda Eye Hospital, explains about "Branch Retinal Vein Occlusion (BRVO)", is a retinal vascular condition where one of the branches of the central retinal vein becomes blocked. Unlike Central Retinal Vein Occlusion, where the main retinal vein is affected, BRVO involves only a particular branch of the venous system supplying a specific area of the retina. Even though the blockage is localized, the visual impact can still become significant depending on the area involved and the severity of vascular compromise.One of the major clinical signs seen in BRVO is retinal hemorrhage. During ophthalmic examination, hemorrhages may be identified along the affected retinal branch. In some patients, the blockage may occur in smaller peripheral branches of the retinal circulation. When minute peripheral vessels are involved, the patient may experience peripheral visual field defects rather than immediate central blurring alone.As circulation becomes compromised, retinal hypoxia can develop. Hypoxia means that the retinal tissue is not receiving adequate oxygen supply because of impaired blood flow. The body then attempts to compensate for this reduced circulation by forming collateral vessels. These collateral vessels are alternate vascular channels developed naturally in an attempt to bypass the obstruction and restore circulation. The newly formed vessels are delicate and fragile. They may not always provide stable circulation and in some cases, may increase the risk of further vascular complications.In Ayurveda, BRVO is not approached merely as a localized retinal disorder. The pathology is assessed by the involvement of Doshas, vascular obstruction and the disturbance affecting retinal nourishment and circulation. The obstructive component is understood predominantly through Kapha involvement. Kapha, when altered from its normal state, can contribute to blockage within the channels carrying nourishment and circulation.When the condition becomes more severe, especially when there is significant hemorrhage, congestion, inflammatory activity or vascular compromise, both Pitta and Kapha may become involved together. Pitta can affect Raktha Dhatu. BRVO is not considered an easy to manage. The retinal tissue is delicate and once circulation becomes affected, maintaining visual function requires careful and structured management. Treatment is planned only after assessing the patient’s systemic condition, retinal findings, vascular status and stage of disease progression.Shodhana Chikitsa. The purpose of Shodhana is not viewed as general detoxification, but as a planned therapeutic process aimed at helping remove obstruction and restore proper movement . In conditions where vascular blockage and Dosha accumulation are contributing significantly to pathology, carefully selected Shodhana procedures may help in reducing the obstructive component and supporting healthier circulation.Clearing the obstruction is important because persistent stagnation within the channels can continue to affect retinal nourishment. Treatments are not generalized procedures. They are individualized according to the patient’s strength, stage of disease, associated systemic conditions and retinal status. Continuous supervision is essential during management.Another important aspect of Ayurvedic management is maintaining the integrity and health of the vasculature itself. Ayurveda describes the “Sara” property of Kapha as contributing to nourishment, stability and healthy tissue support. Treatment is not aimed only at reducing Kapha, but also at restoring its healthy functional qualities of vascular tissues remain supported and stable.
