Diabetes is responsible for 12% cases of blindness in US every year. Vision loss due to diabetes is caused by following medical conditions.

  • Lens loses its focus: Some fluids are accumulated in lens of eye. It affects the focusing ability of lens and vision gets out of focus as curvature of lens is disturbed. But this condition can get better if the sugar level is controlled.
  • Glucose harms blood vessels in retina: High blood sugar is harmful for tiny blood vessels in retina. It narrows them and blood flow is decreased in retina. At this stage no vision loss occurs and it can be reversed if sugar level is controlled.  
  • Macular edema: In this medical condition new blood vessels may form in retina to provide proper amount of blood to retina. These new blood vessels are fragile and sometimes get burst causing blood loss in retinal region which blurs the vision and sometime responsible for complete sight loss.
  • Damage to optic nerve: Optic Nerve is that nerve that transfers the vision signals into our brain and brain coverts these signals into image. Due to above mentioned condition the pressure on eyes increases and it can harm the performance of optic nerve and may damage it. According to some researches, those who are suffering from diabetes from past 25 years are more susceptible to nerve damage. If that nerve damage occurs in your optic nerve then you may go blind.
