A Critical understanding of Cone Rod Dystrophy (CRD) and its Ayurvedic interventions - A Case Report

Abstract

CRDs are Inherited Retinal Dystrophies that belong to the group of Pigmentary Retinopathies (Prevalence 1/40000). Is characterized by Primary Cone involvement or sometimes by concomitant loss of both Cones and Rods that explains the predominant symptoms of CRDs; Decreased Visual Acuity, Colour Vision Defects, Photophobia and Decreased Central Vision, later followed by progressive loss in Peripheral Vision and Night Blindness. Currently, there is no therapy that stops the progression of the disease or restores the vision and the visual prognosis is poor. The only Intervention of CRDs in contemporary science is using Low Vision Aids and Genetic Counselling. Hence Multidisciplinary Approach from Ayurvedic science plays a vital role in the restoration of vision. Though there is No direct reference available in our classical Ayurveda text, the different stages of CRD can be simulated with the conditions which are mentioned in Dristigatagata Roga like, Pittavidagdha Dristi, Hrsvaja, Dhumadarshi and Vataja Timira. Patient is thoroughly examined based on Roga and Rogi Bala and advocated multidisciplinary interventions. This helped this patient in improving the vision and as a prophylactic in arresting or delaying the progression of disease.
