Differential Diagnosis for Goopy Eyes

• Single most likely diagnosis
  • Conjunctivitis: This is the most common cause of goopy eyes, often due to a viral or bacterial infection. The presence of discharge, redness, and irritation supports this diagnosis.
• Other Likely diagnoses
  • Blepharitis: Inflammation of the eyelids can cause goopy eyes due to the accumulation of debris and discharge. It's often associated with itching, redness, and swelling of the eyelids.
  • Dry eye syndrome: Although it may seem counterintuitive, dry eyes can sometimes produce a goopy discharge due to the body's attempt to compensate for the lack of tears.
  • Allergies: Seasonal or environmental allergies can cause conjunctival irritation, leading to goopy eyes.
• Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
  • Gonococcal conjunctivitis: A rare but serious cause of goopy eyes, particularly in newborns or individuals with a history of sexually transmitted infections. It requires prompt treatment to prevent complications.
  • Chlamydial conjunctivitis: Similar to gonococcal conjunctivitis, chlamydial conjunctivitis is a serious infection that can cause goopy eyes and requires prompt treatment.
  • Endophthalmitis: A rare but potentially devastating infection within the eye that can cause goopy eyes, severe pain, and vision loss.
• Rare diagnoses
  • Dacryocystitis: Inflammation of the tear duct can cause goopy eyes, particularly if there's an obstruction or infection.
  • Canaliculitis: Infection of the canaliculi (small ducts in the eyelid) can cause goopy eyes and requires specific treatment.
  • Phlyctenular keratoconjunctivitis: A rare inflammatory condition that can cause goopy eyes, often associated with other systemic conditions.
