Astigmatism is a pathological change in vision in which the light beam is incorrectly focused on the retina of the eye. In normal condition, the cornea and lens have a spherical rounded shape. A ray of light passing through them gathers on the retina at one point. With astigmatism, the sphericity is broken, has different Continue reading

If for any reason there is an obstacle to the excretion of secretions, stagnation occurs in the lacrimal gland. Stenosis or blockage (complete Continue reading

Cataract is a pathological process, as a result of which the optical properties of the lens of the eye change. As the cataract develops, the lens loses elasticity, becomes cloudy, gradually losing the ability to pass and focus light rays on the retina of the eye. Most often, this process is associated with an age Continue reading

Intraocular pressure (IOP) or ophthalmotonus is an important diagnostic criterion for the normal functioning of the eye. Inside it is a liquid that exerts the necessary pressure on the walls of the eyeball. This helps to maintain the shape of the eye, protect it from deformation. Also, this criterion ensures optimal blood circulation in the Continue reading
