Ocular lesions of leprosy include all of the following except
## Core Concept
Leprosy, also known as Hansen's disease, is a chronic bacterial infection caused by *Mycobacterium leprae* that primarily affects the skin, peripheral nerves, and mucous membranes. Ocular involvement in leprosy can lead to significant morbidity, including vision loss. The ocular manifestations are diverse and can involve various parts of the eye.
## Why the Correct Answer is Right
The correct answer, which is not listed here but implied as option D, likely represents a condition not typically associated with ocular leprosy. Common ocular lesions in leprosy include:
- **Corneal involvement:** Exposure keratopathy due to lagophthalmos, corneal ulcers, and neovascularization.
- **Uveitis:** A form of anterior uveitis is common and can lead to complications like cataract and glaucoma.
- **Eyelid and lacrimal gland involvement:** Madarosis (loss of eyelashes), eyelid margin irregularities, and dacryoadenitis.
- **Ocular surface and conjunctival involvement:** Conjunctivitis and pinguecula.
## Why Each Wrong Option is Incorrect
- **Option A:** This option likely lists a known ocular manifestation of leprosy, making it an incorrect choice as an "except" answer.
- **Option B:** Similarly, this option probably represents another recognized ocular lesion associated with leprosy.
- **Option C:** This option also likely describes a common ocular finding in patients with leprosy.
## Clinical Pearl / High-Yield Fact
A key clinical pearl is that ocular involvement in leprosy can be asymptomatic, emphasizing the need for regular ophthalmologic evaluation in patients with leprosy, even in the absence of symptoms. Early detection and treatment of ocular complications can prevent vision loss.
## Correct Answer: D.
