Which of the following is NOT a common cause of neurotrophic keratitis?

Neurotrophic keratitis is a condition characterized by decreased corneal sensation, which leads to impaired healing and can result in corneal ulcers and even perforation. The common causes of neurotrophic keratitis are typically associated with conditions that affect the sensory nerves of the cornea.

Herpes zoster can lead to neurotrophic keratitis due to the damage inflicted on the ophthalmic branch of the trigeminal nerve. This viral infection can cause various ocular complications, including a decrease in corneal sensitivity.

Diabetes is also well-known to contribute to neurotrophic keratitis. The metabolic effects of diabetes can lead to neuropathy, which may affect the corneal sensory nerves. Patients with diabetes are at a higher risk for various ocular conditions, including neurotrophic changes in the cornea.

Stroke can result in neurotrophic keratitis as well, particularly if it impacts the areas of the brain that are responsible for sensory integration or if it affects the trigeminal nerve pathways. When sensation is diminished due to neurological damage, corneal health can be compromised.

In contrast, systemic lupus erythematosus (SLE) is primarily an autoimmune disorder that affects various organs but does not specifically target or damage the corneal nerves.
