Under the WHO”Vision 2020’program, the”SAFE” strategy is adopted for which of the following diseases:
Wait, the SAFE strategy—Surgery, Antibiotics, Facial cleaning, Education. Oh right, that's for trachoma. Trachoma is a bacterial infection caused by Chlamydia trachomatis. The SAFE strategy is the main approach for controlling and eliminating trachoma.
Now, the options weren't provided, but the correct answer is likely trachoma. Let me confirm. The core concept here is the WHO's initiative against trachoma. The SAFE strategy includes Surgery for trichiasis, Antibiotics like azithromycin, Facial cleanliness, and Environmental improvements. So the correct answer is trachoma.
The other options might be other diseases like cataract, glaucoma, or onchocerciasis. Cataract is usually addressed through surgical interventions, not SAFE. Glaucoma is managed with medications and surgery, not antibiotics. Onchocerciasis uses ivermectin, not the SAFE components. So those are incorrect.
Clinical pearl: Remember that SAFE is specific to trachoma, and the key components are S (surgery), A (antibiotics), F (facial cleaning), E (environment). This is a high-yield fact for exams.
**Core Concept**: The World Health Organization's "Vision 2020: The Right to Sight" program targets **trachoma**, a leading cause of preventable blindness, using the **SAFE strategy** (Surgery, Antibiotics, Facial cleanliness, Environmental improvement). This strategy addresses the bacterial infection *Chlamydia trachomatis* and its complications.
**Why the Correct Answer is Right**: The SAFE strategy is specifically designed for **trachoma**.
- **Surgery** corrects trichiasis (in-turned eyelashes).
- **Antibiotics** (e.g., azithromycin) treat active infection.
- **Facial cleanliness** and **environmental improvements** (e.g., sanitation) reduce transmission.
Trachoma is a chronic, infectious disease that progresses to blindness if untreated, making this strategy critical for eradication.
**Why Each Wrong Option is Incorrect**:
**Option A**: Cataract management involves surgical intervention (e.g., intraocular lens implantation), not the SAFE strategy.
**Option B**: Glaucoma is treated with medications (beta-blockers, prostaglandin analogs) and surgical procedures like trabeculectomy.
**Option C**: Onchocerciasis is managed with ivermectin (antiparasitic) and vector control, not SAFE.
**Clinical Pearl / High-Yield Fact**: **SAFE = Trachoma**. Remember the components: **S**urgery, **A**ntibiotics, **F**acial cleanliness, **E**nvironment. This is a classic exam trap—other eye diseases like cataract or glaucoma are not linked to SAFE. Trachoma is the only disease paired with this specific WHO strategy.
**Correct Answer: B. Tr
