Most of the redness and pain in the corners of the eyes are still associated with bacterial infections. Consider inflammation of the lid gland caused by Staphylococcus aureus, which is often referred to clinically as mydriasis and pinhole. Once this occurs, topical anti-inflammatory treatment with levofloxacin solution or tobramycin solution can be applied 4-6 times daily. If it is more convenient, using 1-2 times more is also helpful for the improvement of the condition. It is best to apply gatifloxacin or tobramycin eye ointment once at night before going to bed, which will maintain the antibiotic effect during the night and will help the recovery of the condition. If the redness and pain are heavy, you can also take oral antibiotics, such as cephalosporin, which will speed up the course of the disease, and the redness and pain will heal more quickly.
