Retina - Everything you need to know about it

Retina is the innermost layer of the eye and is light sensitive in nature. When we see an object, the light rays pass through the lens in our eyes and fall on the retina. They get converted into neural signals/impulses here and the optic nerve carries these visual stimuli to the brain that translates them back as images. Now if you are a Harry Potter fan, then consider the retina as the platform 9 ¾ (the entry point to the world of magic). If something goes wrong here, then nothing reaches your center for imagination (the brain) and your vision to the beautiful world stays completely cut-off.

The tale behind the play

The retinal layer is present in the back of the eye and almost at its center it is a pigmented portion called the Macula. It is this pigmented portion that attributes to the sharpness of vision, be it when you are reading a newspaper or driving your car. Retinal disorders could either affect the entire retina or the macula alone. Here are some common ailments affecting the retina:

  • Diabetic Retinopathy – this develops in patients affected by diabetes
  • Retinal Degeneration – involves degeneration of the retina due to death of its cells
  • Macular Degeneration – cells of the macula deteriorate leading to blurry vision
  • Macular hole – yes, you guessed it right; it’s a hole in the macula which could lead to distorted imaging
  • Retinal Detachment – a condition where the retina is torn and is pulled away from the back of the eye
