Welcome to icliniq.com.

This is the age where you get posterior vitreous detachment. It is a naturally occurring age-related phenomenon where the vitreous jelly separates from one's retina and in this process, one might experience a ring-like floater and probably some flashes.

Some warning signs you can watch out if there is something abnormal:

  1. Many floaters instead of one.
  2. Size of floater increases suddenly.
  3. A significant decrease in vision.
  4. Too many flashes.

If these occur, please consult a vitreoretinal expert ophthalmologist for a dilated fundus examination to rule out any areas of weakness in the retina. Till then, start Nepafenac eye drops once at bedtime to hasten the PVD process.
