Many people find their eyes red when they are not expecting it and have not received any damage, what is going on? There are two types of red eyes: one is bleeding and the other is congestion. The following is a specific description of what is going on with red eyes and what conditions are caused by them.
1, eye red may be eye bleeding: ruptured eyelid skin injury manifested as bleeding, bright red easily identified; small bleeding spots on the eyelid skin seen after blunt eye injury, violent cough; high fever sepsis can have large bleeding spots; purplish red subcutaneous bruising is common in heavier direct eye injuries, but also from head, nose, sinus injuries affecting the eye; fracture of the top of the orbit can cause upper eyelid bruising, orbital floor, skull base fracture can cause Fractures of the orbital floor and skull base can cause bruising of the lower eyelid, and fractures of the orbital apex often cause bruising of the lateral eyelid.
Subconjunctival hemorrhage is streaky, flaky, irregularly shaped, bright red, and purplish red with massive bleeding; common causes are: ocular trauma, violent cough, dry stool, forceful eye rubbing, and arteriosclerosis in the elderly. When there is often bleeding in the eye without obvious reasons, you should seek medical attention to check whether there is a systemic bleeding disorder.
2, eye redness may be eye congestion: eye congestion is often caused by inflammation, eyelid congestion performance lid skin redness, often accompanied by fever, swelling and pain, conjunctival congestion performance vasodilatation. There is also a distinction between conjunctival congestion and ciliary congestion.
(1) Conjunctival congestion is a condition in which the conjunctiva or bulbar conjunctiva of the eyelid is significantly congested at the peripheral part of the eyelid, but not near the edge of the cornea. Infectious inflammation has a mucopurulent discharge (commonly known as ophthalmoplegia) with no visual effects.
(2) Ciliary congestion manifests as circumferential congestion around the outer corneal rim, flushed or dark red, with unclear vascular course. In severe cases, the congestion may be mixed, i.e., conjunctival congestion and ciliary congestion are present at the same time. Ciliary congestion should be taken seriously as an indication of disease in important parts of the eye, commonly seen in various causes of keratitis, corneal ulcers, corneal foreign bodies, sclerenitis, iritis, glaucoma, endophthalmitis, etc., which can have varying degrees of visual impact.
3, allergic reactions can also cause eye redness: such as allergy to topical atropine, antibacterial agents, etc., or oral excess iodine and arsenic preparations, causing conjunctival inflammation; in addition, such as allergy to bacterial toxins caused by corneal stromalitis, iridocyclitis, etc.
The above is an introduction to what is going on with eye redness. In addition to the above, there are many reasons for eye redness to occur, the most common being eye infection. Such as corneal ulcers, systemic infections such as typhoid, cold, measles, typhus, pneumonia, septicemia, etc. caused by conjunctivitis and metastatic ocular content inflammation, eyelid dermatitis near the eye, blepharitis, mydriasis or orbital infection, etc. can cause eye redness.
