<prompt> Visual fields diagnosed by -PachymetryPerimetryCorneal topographyOptical coherence tomography  <response>: Ans. is B. Perimetry Field of vision o The extent of the normal visual field is limited in an individual by anatomical features such as the brow superiorly, the nose nasally medially and the cheek inferiorly. The field for a white target extends:- Upwards superior - 50-60 degrees Downwards inferior - 70-75 degrees Inwards nasally - 60 degrees Outwards temporally - 90-100 degrees o The tests used to measure the field of vision are i Confrontation test. ii Perimetry :- Kinetic perimetry, or automated perimetry. o Visual field defects are best detected by Goldmann kinetic perimetry and Humphery automated threshold perimetry. Goldman scale in perimetry.
