Summary

The purpose of this study is to assess wether the SONDA visual field test is suitable for patients with a supra sellar tumour.

Detailed description

The objective of this study is to determine whether SONDA is non-inferior in predicting visual field limitations compared to the SAP in patients with a (supra)sellar tumor. The study population will be made up of patients with a (supra)sellar tumor complicated by compression of the optic chiasm as well as healthy controls. The patients will be asked to join the study when the patients are referred to the UMCG for further diagnostics and treatment. In case the patients show signs of visual field loss the patients will be asked to participate in the study. The researchers will reuse data from healthy controls collected in previous studies where possible and, if necessary for age matching, recruit new participants. Participants will be asked to perform the SONDA test before and after surgery. The first time the participants will perform the test twice and will also perform routine eye test and be asked to fill in a questionnaire to evaluate the experience.
