Differential Diagnosis for Watery Eye and Painful Eye
- Single Most Likely Diagnosis
- Conjunctivitis: This is the most likely diagnosis due to the common presentation of watery eyes and pain, which can be caused by viral or bacterial infections.
- Other Likely Diagnoses
- Dry Eye Syndrome: Although it seems counterintuitive, dry eye syndrome can cause watery eyes as a reflex to the dryness, and it can also cause pain.
- Blepharitis: Inflammation of the eyelids can cause watery eyes and pain due to the irritation of the eyelids and the conjunctiva.
- Corneal Abrasion: A scratch on the cornea can cause severe pain and watery eyes due to the irritation of the cornea.
- Do Not Miss Diagnoses
- Acute Angle-Closure Glaucoma: This is a medical emergency that can cause severe eye pain and watery eyes, and if missed, can lead to permanent vision loss.
- Orbital Cellulitis: A bacterial infection of the tissues surrounding the eye can cause pain, watery eyes, and swelling, and if not treated promptly, can lead to serious complications.
- Endophthalmitis: A severe infection of the inner eye can cause pain, watery eyes, and vision loss, and requires prompt treatment to prevent permanent damage.
- Rare Diagnoses
- Sjögren's Syndrome: An autoimmune disorder that can cause dry eyes and mouth, but can also cause watery eyes as a reflex to the dryness.
- Trigeminal Neuralgia: A rare condition that affects the trigeminal nerve and can cause severe pain in the face, including the eyes.
- Cluster Headaches: A rare type of headache that can cause severe pain around the eye and watery eyes.
