Dry eye reduces vision and reduces the quality of vision. Dry eye mostly affects the cornea. The cornea only itch in the tissues around it. The anterior lens of the eye, the cornea, is a very delicate and delicate tissue. The system is easily damaged by external and internal factors. It takes water quickly, swells or leaves its water and dries up.
Dehydration: The decrease in the aqueous (water) part of the tear causes the epithelium to become dehydrated. Being dehydrated spoils the transparency. You can think of it as shrinking apricots left in the sun.
Deterioration of transparency: Transparency deteriorates quickly. When the eye dries, the gap in the middle of the cells approaches each other, the transparency deteriorates, and light reflections appear.
Injury to the epithelial layer: Epithelial injuries occur quickly. The epithelium is the layer that covers the corneal surface. It is easily damaged. Dry eye impairs the organization and resistance of this place. When the patient scratches, injury occurs in the form of cell fragmentation. This impairs vision. This is our purpose in saying that the patient does not scratch when his eyes are itchy.
Instant changes in vision: Instant changes in the cornea cause deterioration in day-long vision. Especially those who use mobile phones and computers during the day are very affected by this. As the cornea dries, its transparency decreases.
Mucus accumulation: When the aqueous (water) decreases, the mucus combines with the oil and deposits, the accumulations plaster the cornea in the form of burrs, causing a decrease in vision.
Light reflections: Epithelial damage due to dry eye, loss of transparency causes light reflections and reduces the quality of vision. Especially when the person is driving in the evening, he realizes it and becomes very uncomfortable.
Staining with Flourescein: Damage in the epithelial layer of the cornea is seen in the form of areas with green dye when viewed with cobalt blue in the biomicroscope when fluorescein dye is dripped.
