Hi and welcome to HCM. Normally sella is occupied by pituitary gland. The empty sella is often discovered incidentally in people with no symptoms. . Sometimes hormonal problems, but usually not. There are several causes of empty sella. Some involve increased pressure in the brain, such as pseudotumor cerebri, which can cause headaches. Some common symptoms associated with empty sella are headache, visual field defects, nontraumatic cerebrospinal fluid rhinorrhea and pituitary hormone abnormalities. It is unlikely that pituitary dysfunction would occur with time, but periodic endocrine and visual field exams were recommended. Your throat infection and eye infection may or may not be related to this. I suggest your to follow your doctors advice for further treatment. All the best Regards Dr Santosh
