Some OSSN is first noticed by patients and their friends. In most cases the diagnosis is made by an optometrist or ophthalmologist.
Unusual looking pterygia and definite cases of OSSN are referred to eye specialists for examintion with the slit lamp microscope.
OSSN may look very like a pterygium and in some cases only surgical removal and examination of the abnormal tissue by a pathologist will confirm the diagnosis.
