Glossary of terms

Visual acuity: Reading optotypes (usually letters) that go from largest to smallest to detect the clarity with which the patient sees.

Retinoscopy: Technique to objectively detect the graduation of the patient without the need to ask if he sees better with one or the other lens. The result is more or less accurate depending on the expertise of the examiner.

Refraction: The best known section of the visual examination. After detecting the base graduation with retinoscopy, we refine the prescription by asking the patient if he sees better or worse with the different lens options that are proposed. Subjective test.

Anamnesis: Collection of information on the general health of the patient, the health related to his vision and family history in order to incorporate it into his medical history.

Ocular Motility: Evaluation of conjugated eye movements. The professional will ask the patient to follow an object with his eyes to assess the coordination of the extrinsic ocular muscles.

Pupillary Reflexes: Evaluation of the pupils to rule out pathologies at the nervous level, autonomous systems and other conditions.

Binocular Balance: Graduation compensation to avoid diplopia (double image) and maladjustments due to graduation changes or high anisometropia (different graduations in each eye).

Accommodation: The eye's focusing system is evaluated for different planes in the distance.

Stereopsis: We measure the patient's ability to calculate distances and depth. Three-dimensional or 3D vision is evaluated.

Visual field: The visual field is the image that an eye perceives in an instant of time. With this test we detect if there are decreases in the peripheral visual field associated with diseases such as glaucoma and other pathologies.

Biomicroscopy: Exploration of the structures of the anterior portion of the eye. We examined the ocular adnexa, eyelids, sclera, conjunctiva, vessels, cornea, anterior chamber, iris, and lens. It is the main instrument in the adaptation of contact lenses. In this exam we detect eye diseases including: cataracts, corneal lesions, meibomitis, styes, chalazion, conjunctivitis, narrow angle glaucoma, uveitis and other conditions.

Color test: We evaluate the patient's ability to perceive the full range of colors. Pathologies such as color blindness are ruled out.

Diagnosis explanation: Professional comments on the findings found during the visual examination.

Retinography: Professional wide-angle photography that allows to evaluate the fundus of the eye (peripheral retina, optic nerve, vascular system, macula and fovea) in a detailed and detailed way. Detects most pathologies such as Glaucoma, Macular Degeneration, Diabetic Retinopathies, Hypertensive Retinopathies, Retinitis Pigmentosa, Incipient Retinal Detachments, Nevus and others.

Ocular Pressure: Measurement of the pressure of both eyes by means of air tonometry. 3 measurements are made on each eye to determine the mean pressure. It detects incipient glaucomas and is essential for monitoring those already detected.
