What is Ocular Surface Disorder?
Ocular surface disorder is a group of eye diseases that may severely affect eyesight and quality of life. The ocular surface consists of the cornea, conjunctiva, eyelids and tear glands, and any disorder in these structures can be classified as an ocular surface disorder (OSD).
OSD is frequently associated with tear film dysfunction that may be due to several conditions, such as dry eye disease and similar symptoms that occur following ocular surgery and corneal erosions. Symptoms may include blurry vision, discomfort or pain, redness and itching, and in severe cases, blindness due to corneal scarring.
A stable tear film is necessary in order to protect your eyes against infection, keep them moist, and clean the surface of your cornea. The tear film is composed of 3 different layers: the lipid, aqueous and mucin layer. All three layers must function properly and be in perfect balance to ensure the adequate production of tears.
Irritation can occur if not enough tears are produced to keep the eye comfortably lubricated or when the eye does not produce an adequate amount of lipids to smooth the tear surface.
An alteration of the lipid layer causes the aqueous layer to evaporate, thus reducing essential nourishing factors that alter the epithelial cell activity and replication. This may result in hyperosmolarity which causes goblet cells to die and reduces corneal glycogen. An irregular lipid layer can cause a reduction in visual acuity.
Symptoms of inadequate lubrication include eye irritation, gritty and itchy eyes, a burning sensation, redness and heavy/swollen eyelids and foreign body sensation.
When treating ocular surface disorder, the goal is to enhance the healing process and achieve symptom relief.
LIPTEAR™ MULTI is a clinically-proven formula to imitate the natural tear film. It forms an elastic shield that restores the right environment for a healthy ocular surface, thus facilitating the healing process of the epithelium and rebuilding a uniform and smooth ocular surface for clear and comfortable vision.
