Episode #16 - Non-Proliferative Diabetic Retinopathy — Understanding the Early Retinal Changes in Diabetes

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 Non-Proliferative Diabetic Retinopathy (NPDR), is one of the early clinical stages of Diabetic Retinopathy. Most people are aware that diabetic retinopathy is a complication associated with diabetes, but many patients do not realize that the condition is not defined by a single symptom alone. It involves a wide range of vascular and retinal changes and therefore both diagnosis and treatment planning can vary significantly from patient to patient.In NPDR, the primary pathological changes occur within the retinal blood vessels. Due to prolonged metabolic and vascular stress associated with diabetes, the walls of the retinal vessels gradually undergo structural changes. Thickening and weakening of the vessel wall may develop over time, leading to bulging of small retinal vessels. As these vessels become fragile, leakage can occur from within the circulation.During retinal examination, these vascular leakages and minute hemorrhages may appear as small red dots scattered across the retina. Although these changes may initially seem minimal, they indicate that the retinal circulation is already becoming affected.Many patients in the early stages may not experience severe vision loss immediately. Instead, they often complain of mild blurring of vision, visual discomfort, hypersensitivity to bright light, fluctuating clarity of vision due to fatigue, blood sugar variation or exposure to strain, heaviness of the eyes or swelling around the eyelids, especially during the morning hours.Because these symptoms can appear gradually, people ignore them during the initial stages. Retinal vascular changes can continue progressing silently. Patients with diabetes, should undergo proper retinal evaluation by an ophthalmologist.From an Ayurvedic perspective, diabetes is understood as a Kapha-dominant disease process. Progression of retinal complications depends not only on diabetes itself, but also on associated lifestyle and dietary factors that may aggravate other Doshas, particularly Pitta.Individuals with unfavorable for ocular health, such as oily, spicy, fried, processed or junk foods, irregular food habits, poor sleep, prolonged exposure to bright light, excessive screen usage leads to Pitta aggravation alongside the Kapha pathology. This combination can further disturb retinal circulation, vascular stability and ocular nourishment.Ayurvedic management is planned after assessing the patient’s Prakrithi, Dosha predominance, vascular status, retinal findings and stage of disease. In patients with Kapha predominance and circulatory congestion, treatment may include therapies such as Nasya, Shirodhara, Kabala, Bidalaka and Aschyothanam.The aim of management is not merely symptomatic relief alone rather to normalize retinal circulation, reducing congestion within the channels, supporting vascular stability, and addressing the leakage tendency occurring from the retinal vessels. Since diabetic retinal disease involves progressive vascular compromise, maintaining healthier circulation and retinal nourishment.Treatment protocols are individualized. Some may predominantly have vascular leakage, others have edema, hypersensitivity, heaviness or visual fluctuation as the major complaint. Medicine selection, external therapies, dietary regulation and treatment individualized.At Matha Ayurveda Eye Hospital, management of Non-Proliferative Diabetic Retinopathy is through detailed clinical assessment, structured inpatient care , continuous monitoring and disciplined follow-up. The emphasis is placed on supporting retinal health, reducing progression, maintaining circulation and helping preserve visual function over time through a systematic and individualized approach.
