### Patient: Doctor, I have been feeling a foreign body sensation in my eye, and my scalp appears irregular. What could be the reason for this?
### Doctor: You may be suffering from a condition called Pterygium. It is a growth of tissue on the white of the eye (sclera) and can cause discomfort and affect vision in severe cases. The irregular scalp may be a less common symptom associated with Pterygium as it shares a similar vascular nature to that of the eye.
