Dry eye is caused by a low amount of tears in the eyes. Patients with dry eye often complain that their eyes tire easily, making it difficult to read and watch television. These difficulties occur because the frequency of eye transients is significantly reduced when work requires concentration. When the frequency of transients is significantly reduced, the tear film evaporation time will be significantly longer. What are the symptoms of dry eye syndrome? Let’s find out. The symptoms of dry eye are divided into the following types: tear deficiency dry eye, which means that the tear secretion is reduced and evaporation is too strong, and the normal tear film on the surface of the eye is accelerated and dried up. The more common symptoms of dry eye are dryness and foreign body sensation in the eyes. Other symptoms include burning sensation, itching, photophobia, redness and pain, blurred vision and easy pu fatigue, and sticky filamentous discharge. If any of these symptoms are present, a careful medical history should be taken to find the cause. Symptoms of dry eye include dryness, foreign body sensation, pain, photophobia burning sensation, itching, eye redness, visual fatigue, blurred vision, fluctuating vision, itching, stinging, dryness, unsuitability, foreign body sensation, easy visual fatigue, heavy eyelids, irritability, and difficulty concentrating. In severe dry eye, it can cause significant loss of vision and affect work and life, and even lead to blindness. The above symptoms of dry eye can be aggravated in hot and dry climates, as well as when exposed to certain chemicals, dust, smoke, and prolonged exposure to computer screens. In cases of exacerbation dry eye symptoms manifest as follows: oily areas form around the edges of the eyelids with seborrheic blepharitis or scabs. Removing them causes blood to ooze from the surface. The tear film decreases in thickness and a mucousy debris or fibrous secretion appears. The conjunctiva becomes lustrous, thickened, edematous, hemorrhagic, sometimes encrusted with secretions, and in more severe cases the conjunctiva may appear keratinized. When corneal staining tests are done with fluorescein, punctate pooling occurs. Clinical indicators that usually help to diagnose dry eye are: tear gland rupture time, tear gland secretion test and diagnostic staining. To have the above symptoms of dry eye, dry eye can still be diagnosed even if the objective test is negative. On the contrary, even if the objective examination is positive, but the patient does not have the above symptoms, then the dry eye diagnosis should be made with great caution.
