Cause: They are caused by sun damage and irritation. They can affect lighter colour individuals more than the darker ones.
Exam: Pinguecula and Pterygium can be found by Optometrist during routine eye exams. If size, colour and thickness changes significantly over a short period of time, make sure to follow up with an Optometrist to see if it might become malignant.
Treatment: Surgical removal can be used if pinguecula or Pterygium threatens the line of sight, affecting the cornea covering the pupil. It may grow back after removal. It's always best to prevent it by seeing your Optometrist for routine eye exams yearly and wearing UV protection or sunglasses.
