Retina eye examination is not complete without retinal examination. Sometimes a person may have serious vision threatening problem in spite of 6\6 vision eg -- diabetic retinopathy, branch vein occlusion, retinal detachment, retinal degeneration and tear etc.
Diabetes & Retinopathy Diabetic Retinopathy is a disease affecting small blood vessels of the Retina. It has the dual features of vascular leakage and vascular occlusion. In diabetes, retinal small vessels undergo certain changes resulting into weakening of blood vessel wall. These causes leakage, retinal edema and hemorrhages in retina & vitreous. usually it takes 10 to 30 years to develop diabetic changes in eye since the onset of diabetese. good control of diabetes along with hich may accelerate the onset of retinopathy- Pregnblood pressure [ if it is present] can slow down the eye changes but can not prevent diabetic retinopathy. poor control of diabetes will certainly accelerate the retinopathy.
Other factors wancy, anemia, systemic hypertension, renal disease.
