How Is Glaucoma Diagnosed?
The ophthalmologist carries out various examinations to diagnose glaucoma. The eye pressure will be measured, but the key to detection is an examination of the optic nerve head.
An ophthalmological examination includes eye pressure measurement and a visual acuity test. An examination of the interior surface of the eye (the ocular fundus) with an assessment of the optic nerve head is essential. The field of vision can also be tested if previous examinations provided an indication of glaucoma.
It is typical for glaucoma that the central vision is conserved for a long time despite considerable losses of the field of vision near the visual centre. These field losses can be compensated for by the vision field of the unaffected eye. For this reason, glaucoma is initially hardly noticed in everyday life, which makes it all the more dangerous.
Further specialized examinations can follow, such as the measurement of eye blood vessel width and the photographic documentation of the optic nerve head.
