The study includes 25 cases of pituitary adenomas. Most common age group by pituitary tumors falls between 41-50 years of age. Male: Female
incidence of these tumors is 1: 2.12. Most common clinical symptoms in our series are visual disturbances followed by headache. Optic nerve
involvement is other common clinical nding presenting in form of decreased vision or loss of vision, eld defect or fundus changes. Commonest
eld defect is bitemporal hemianopia. MRI is the diagnostic investigation of choice in pituitary tumors to dene extent, invasion and relationship to
major vessels and nerves. Approximately half (44%) of the patients exhibited normal preoperative pituitary function in form of baseline hormone
prole. Increased GH level (32%) followed by hyperprolactinemia (20%) are the most common endocrinologic abnormalities. Total/near total
removal was done in 21 patients (84%) and subtotal removal done in 4 patients (16%). Adjuvant therapies were given in 5 patients. Two patients
were given radiotherapy and 3 were given pharmacotherapy. Post operative complications were CSF leak, diabetes insipidus and meningitis. 20
patients (80%) had improvement in their symptoms including relief from headache, improvement in vision and endocrinal dysfunction. Post
operatively visual functions improved in 13 patients (52%) and it remained stationary in 11 (44%) patients. Only one patient (4%) complained of
worsening of his visual function and it was improved in follow up period
Isolated Traumatic Bitemporal Hemianopia
