Abstract

The value of the MP-1 microperimeter in early diagnosis of pituitary tumours by detection of changes in macular sensitivity is described. A 21-year-old female presented with blurred vision in the right eye. Ophthalmic examination was unremarkable. Static perimetry of the central visual field (30°) was performed by use of a Humphrey automatic perimeter, and the retinal sensitivity of the 12 central degrees was measured by use of the MP-1. Static perimetry revealed a peripheral visual field defect without involvement of the macular region. The MP-1 revealed an important loss of sensitivity (3.4 ± 4.8 dB) in the central 12°. Magnetic resonance imaging revealed a pituitary adenoma with sellar and suprasellar extension. Three months after surgical removal, use of the MP-1 revealed complete recovery of the sensitivity (19.28 ± 2.5 dB), fixation location, and fixation stability of the right eye. In pituitary tumours, the presence of a sub-clinical form of macular involvement can be demonstrated and followed-up accurately by use of the MP-1.
