Study on analysis of Nidana and Samprapti in Diabetic Retinopathy (Pramehaja Timira)
India is set to emerge as the Diabetic capital of the world. Diabetic retinopathy (DR) occurs due to diabetic complication that effects or damages the blood vessels of light sensitive tissue of the retina. It is also observed that patients who have diabetes more than 10 years show some form of DR. Prevalence in India ranges from 17.6 - 28.2%. According to Ayurveda in Netra Prakashika - Shri Pujyapada Mahamuni, mentioned Madhumeha as a cause for Netraroga. DR can be termed as Madhumehajanya Timira. Avarana and Dhatukshaya have important role in development of DR due to prolonged and uncontrolled hyperglycemia. All the tridosha along with Rakta Dosha and Saptadhatu with four internal Dristipatala of eye are effected in Pramehaja Timira in different stages of disease. In the early stages of diabetic retinopathy there may be minimal symptoms. As condition progresses, DR symptoms may include like floaters, blurred vision and visionloss. There are two types of diabetic retinopathy: Early DR and Advanced DR. The longer period having diabetes and the less controlled blood sugar, are more likely to develop with this eye complication. Hereby an attempt is made in this article to understand the Nidana and samprapthi which leads to madhumehaja Timira which can be considered as a silent killer of vision.
