Premium Diabetic retinopathy Ophthalmology Retina
The retina is a layer of tissue inside of the eye. It is responsible for sending message from the optic nerve to the brain. If the retina detaches‚ then it will be pulled or lifted from its normal position. Permanent vision loss can result if this problem is not corrected right away. The retina is attached to vitreous‚ which is a gel-like substance. The vitreous becomes more watery and thinner as we age. The change in shape can cause the vitreous to pull away from the retina. As a result of this
