A window to the brain for the diagnosis of diseases

The eye and the brain

The eye is a complex structure closely related to the brain, connected by the optic nerve. This “window” to the brain is also a window to the body; by means of an ocular examination, diseases as varied as diabetes, arterial hypertension, thyroid disorders, tumors or systemic infections can be diagnosed.


The study of the optic nerve enables the diagnosis and stratification of many neurological diseases, such as multiple sclerosis, Alzheimer’s, or dementia. Tests such as campimetry, Heidelberg tomography or visual evoked potentials inform us of the state of the neurons of the optic nerve and consequently, of the central nervous system in its entirety.


We include many genetic studies; among the most characteristic pathologies revealed are optical atrophies, glaucoma and macular degeneration. In these, screening and early detection are vital to avoid future complications, and genetics is the main weapon for the job.
