Young people have a white ring around the edge of the black part of the eye.
There are various reasons for a white ring appearing at the edge of the black part of the eye in young people, generally including infection, inflammation, allergies, immune disorders, and eye fatigue. It may be caused by conditions such as dry eye syndrome, keratitis, conjunctivitis, pinguecula, or corneal degeneration. In most cases, these conditions can be treated with medication.
1. Dry Eye Syndrome
Insufficient tear secretion may lead to symptoms such as dryness, stinging, and itching in the eyes, and may also result in a white ring around the edge of the black part of the eye. Symptoms can be relieved under medical guidance using medications such as carbomer ophthalmic gel, sodium hyaluronate eye drops, or Shizhu Mingmu eye drops.
2. Keratitis
Keratitis occurs when weakened corneal defenses are triggered by pathogenic factors, leading to inflammation of the corneal tissue. It is recommended to use tobramycin eye drops under medical supervision, or take oral medications such as cephalexin capsules or ofloxacin tablets to eliminate pathogens and relieve symptoms.
3. Conjunctivitis
Conjunctivitis is usually caused by chemical irritation or microbial infection, and may also result from immune system disorders. Symptoms include dryness, itching, foreign body sensation, increased eye discharge, and pain, often accompanied by a white ring around the edge of the black part of the eye. Treatment typically involves medications such as ofloxacin eye ointment, pranoprofen eye drops, or tobramycin-dexamethasone eye drops.
4. Pinguecula
Prolonged exposure to ultraviolet light or contact with toxic or harmful substances may lead to pinguecula, causing damage to the conjunctiva and forming a triangular elevated lesion. For persistent pinguecula, cases with cosmetic concerns, or when conservative treatment fails, surgical removal via microscopic pinguecula excision may be performed under medical supervision to restore normal condition.
5. Corneal Degeneration
Corneal arcus (gerontoxon) is commonly caused by deposits of cholesterol, cholesterol esters, phospholipids, and triglycerides in the peripheral region of the cornea, resulting in a gray-white circular opacity. If vision is not affected, specific treatment is usually unnecessary.
If any eye discomfort occurs, prompt medical consultation is essential for timely diagnosis and treatment. Self-medication or blind treatment should be avoided to prevent delays in proper care.
