The eye specialist may request a series of painless useful tests for the diagnosis of AMD. These tests will reveal if there is any damage in your eyes and/or impaired vision.

Visual test

Visual acuity test. Measures your ability to see objects at different distances.

Rejilla Amsler

Amsler grid. A sheet of squared paper with a point in the centre, used to test if you notice any wavy lines or if any disappear.

Drop in the eye to dilate it

Dilated eye exam. The doctor will need to apply a few drops which dilate the pupil in order to examine the inside of your eye. The effect of the drops can last from 4 to 24 hours, depending on the patient’s susceptibility.

Machine for fundoscopy

Fundoscopy or ophthalmoscopy. A light source is used to examine the fundus (back) of the eye, i.e., the retina, the choroid, the blood vessels and the optic disc.

Tomografía coherencia óptica

Optical coherence tomography (OCT). Imaging technique that uses light waves to take photographs of your retina and therefore measure and map its thickness.


Autofluorescence. Autofluorescence is a technique used to determine the area affected by retinal pigment epithelium (RPE) atrophy in patients with advanced dry AMD.

cámara para fotografía de fondo de ojo

Eye fundus photography. The ophthalmologist uses a specially adapted camera to photograph the back of your eye.


Fluorescein angiography. This test examines the blood flow in the retina and the choroid, the rearmost layers of the eye.
