Diabetic Retinopathy - Generally Diabetic Retinopathy occurs a long time after the occurrence of diabetes. Usually both the eyes are involved. The main reason for this Roga is Prameha (Diabetics). If Prameha is not treated in time, the circulation through veins and arteries to the Netrapadalas will be decreased resulting in total loss of vision. In modern medical science, the retinal detachment and weakening of the optic nerve cause blindness.
Retinitis Pigmentosa - The connective tissues of the Retina are enlarged and rods and cones are weakened and finally degeneration occurs. Usually the disease starts in the outer layer of retina and gradually progress to the inner layer. If the degeneration is in the periphery, the full vision is diminished and when degeneration occurs in the macula, the central vision is diminished. The first symptom of this disease is night blindness. Retinitis Pigmentosa is found to be a genetic disease which is mostly seen in children, born from blood-related parents.
