Abstract:
The use of optical coherence tomography to diagnose conditions that predominantly affect the photoreceptor layer is postulated as a technique that allows to evaluate the relationship between retinal changes and loss of visual acuity. Two clinical cases are presented on patients with a bilateral decrease of their visual acuity and alteration in chromatic perception. Optical coherence tomography revealed subfoveal focal hypo-reflective defects on the hyper-reflective band (known as the ellipsoid zone).
