Differential Diagnosis for Lithium Grease Exposure to the Left Eye
Single Most Likely Diagnosis
- Chemical Keratitis: This is the most likely diagnosis given the exposure to lithium grease, which can cause chemical burns to the cornea, leading to inflammation and potentially blurred vision. The fact that symptoms have persisted for 3 weeks suggests a possible chronic or unresolved chemical injury.
Other Likely Diagnoses
- Corneal Ulcer: A possible complication of chemical keratitis, where the cornea becomes infected, leading to an open sore. This could explain the blurred vision and is a direct consequence of the initial chemical injury.
- Conjunctivitis: Inflammation of the conjunctiva, which could be caused by the chemical exposure. While it might not fully explain the blurred vision, it's a common reaction to foreign substances in the eye.
- Dry Eye Syndrome: Prolonged exposure to certain chemicals can disrupt the tear film, leading to dry eye symptoms, including blurred vision due to irregularities on the surface of the eye.
Do Not Miss Diagnoses
- Endophthalmitis: Although less likely, this is a severe infection within the eye that can result from any penetrating injury, including chemical burns. It's critical to diagnose and treat promptly to prevent vision loss.
- Glaucoma: Chemical injuries can lead to increased intraocular pressure, potentially causing glaucoma. This condition can lead to permanent vision loss if not addressed.
Rare Diagnoses
- Sympathetic Ophthalmia: A rare, inflammatory condition that can occur after a penetrating eye injury, including chemical burns. It affects both the injured and the uninjured eye, potentially leading to severe vision loss.
- Corneal Perforation: A rare but possible complication of severe chemical burns, where the cornea ruptures. This would require immediate surgical intervention to preserve vision.
