Ocular congestion can be eliminated as soon as possible with targeted eye drop treatment and related treatments. There are many causes of eye congestion, such as conjunctivitis, keratitis, iritis, impingement, dry eye, visual fatigue, conjunctival calculi, glaucoma, etc. Different medications and treatments can be used for different causes. For infectious conjunctivitis and keratitis, different antibiotics, antiviral or antifungal eye drops are needed depending on the pathogenic microorganism; for allergic conjunctivitis, anti-allergy treatment is needed; for iritis, hormone and pupil dilatation treatment are needed; for impingement, extraction or surgical correction is needed; for dry eye and visual fatigue, adequate rest and artificial tear drops are needed; for conjunctival stones, removal of stones and antibiotic eye drops are needed Glaucoma requires medication to lower eye pressure or surgery. More rest, less eye use and local cold compresses can also help reduce eye congestion. If you want to eliminate eye congestion quickly for aesthetic reasons, you can use decongestant eye drops (e.g., noninflammatory maleic acid naphthazoline hydrochloride drops), which can rapidly shrink local capillaries and eliminate conjunctival congestion, but cannot treat the original disease and cannot be used for a long time. In short, eye congestion should be analyzed and targeted treatment to remove the cause should be taken in order to eliminate it as soon as possible.
