Aim: To evaluate red dot perimetry as a simple and accurate perimetric assessment for patients with pituitary tumours.
Methods: This was a retrospective review of the visual fields of 15 patients with pituitary tumours using red dot perimetry or Humphrey visual field assessment. Eleven patients had some visual field defects and 4 had normal visual fields. The red dot perimetry and Humphrey visual field results were tabulated and compared. The sensitivity and specificity of red dot perimetry for detecting visual field defects were calculated.
Results: The sensitivity of red dot perimetry was 100% (11 of 11 patients) and the specificity was 100% (4 of 4 patients).
Conclusion: Red dot perimetry is a useful tool for detecting visual field defects in patients with pituitary tumours.
