Visual Improvement after Endoscopic Endonasal Transsphenoidal Excision of Pituitary Gland Tumor

Abstract

Objective: To evaluate the frequency of improved visual acuity after Endoscopic Endonasal Transsphenoidal excision of pituitary gland tumor.Study Design: Descriptive case series.Materials and Methods: In our study, Pre-operative visual acuity was noted by using the Snellen’s chart. Then patients underwent pituitary gland excision though Endoscopic Endonasal Transsphenoidal approach under general anesthesia. After surgery, patients were shifted in postsurgical wards and then will be discharged from there and were examinedfor 3 months in OPD. Snellen’s chart was used to evaluate patents for visual acuity after 3 months by an experienced ophthalmologist having at least 4 years residency experience If visual acuity increased ≥ 1 line, then improved visual acuity was labeled.Results: Improved visual acuity after pituitary gland tumor excision was seen in 59(89.39%) patients. Age and gender of patients did not show any statistically significant association for improved visual acuity.Conclusions: Results of this study showed that pituitary gland tumor excision through Endoscopic Endonasal Transsphenoidal approach is effective in terms of visual acuity improvement. Our main objectives in pituitary surgery are protection and reinstatement of vision and this surgical approach give maximum cover to vision restoration.
