Hello doctor,

My eye has swelling and is red. The pain is there, but I have not taken any medications. Kindly suggest.



Welcome to

How is your vision? Are you able to see clearly? Are you facing the same issue in both eyes? Did you get hit in the eye or feel like something has fallen in? I would suggest you consult an ophthalmologist regarding this as soon as possible. The most common causes of redness and pain include acute infective conjunctivitis will cause continuous watering and a feeling of sticking together of your eyelids, especially on waking up in the morning. Acute congestive glaucoma increases eye pressure. This causes excruciating pain and generally blurs vision. It also causes you to see rainbow-colored rings around light. Acute uveitis is an inflammation of the uvea inside the eye that presents similar features to glaucoma, and they can go hand in hand. Corneal ulcer or foreign body if you had something fall into or hit your eye. In either case, seeing a doctor is the best as the accurate diagnosis can only be made on slit lamp examination, and treatment can begin once the diagnosis is made. Thank you.

Investigations to be done:

Slit lamp examination.

Differential diagnosis:

Acute conjunctivitis, acute congestive glaucoma, acute anterior uveitis, or a corneal ulcer.

Probable diagnosis:

Acute conjunctivitis.

Treatment plan:

Refer to ophthalmologists for examination.

Regarding follow up:

Review after one day or as required.
