ophthalmological examination

Ophthalmological examinations

Slit lamp

This device allows the examination of the external structures of the eye (eyelids, cornea, conjunctiva) and the intraocular structures (such as the anterior chamber of the eye, the iris, the lens).

Tonometer

This instrument measures the pressure of the eye (e.g. to diagnose glaucoma).

Indirect ophthalmoscope

The ophthalmoscope allows you to visualise the back of the eye, such as the vessels of the retina that you can see on television (image below).

Gonioscopy

This procedure is used to examine the iridocorneal angle and establish whether your dog has a predisposition to glaucoma.

Schirmer's test

This is a quick and simple test to measure tear production.

Fluorescein test

Carried out at the end of the examination, this test requires the application of a dye which makes it possible to highlight wounds (ulcers) on the cornea.

Electroretinography (or ERG)

This is a medical examination that assesses retinal function using electrodes placed on and around the eye and flashes of light. The ERG has an essentially diagnostic role (to highlight retinal degeneration) but also a prognostic role (before performing cataract surgery for example). This examination requires a general anaesthetic.
