Visual field campimetry 25/03/2020

Visual field campimetry is an examination used to assess alterations in the visual field (the portion of space that can be captured by the eye while focusing on a central point).

Thanks to this examination, any kind of loss of periphery vision can be detected, as well as providing a map of this loss, which can guide and improve the diagnosis of certain pathologies (glaucoma, retina disorders, damage in the optic tract, etc.).

In this kind of examination, patients sit in front of the campimeter (a device that is spherical on the inside). Both eyes are examined separately, so patients have to close one eye while the examiner asks them to indicate when they see an intermittent ray of light of different strengths. This flash of light appears in different zones of the visual field of the eye being examined. The same procedure is then repeated for the other eye.

No prior preparation is required on the part of the patient for this kind of study, which is entirely painless and has no side effects.
