**Question:** Treatment of choice of acute dacryocystitis:

---

**Core Concept:** Acute dacryocystitis is an inflammation of the lacrimal sac, usually caused by bacterial infection. It presents with symptoms such as pain, swelling, redness, and discharge in the lacrimal sac area.

**Why the Correct Answer is Right:**

The correct answer, **Option C: Incision and Drainage (I&D)**, involves surgically creating an incision in the lacrimal sac to relieve pressure and allow drainage of the infected material. This procedure helps to eliminate the bacterial infection and reduces the inflammation.

**Why Each Wrong Option is Incorrect:**

**Option A (Surgical Dacryocystorhinostomy - DCR):** This procedure is performed when the lacrimal sac is obstructed, but not when it is inflamed and infected. In DCR, a new passage is created between the lacrimal sac and the nose, allowing the drainage of tears directly into the nasal cavity.

**Option B (Antibiotics alone):** Antibiotics are often prescribed as part of the treatment, but they alone are not sufficient to address the acute inflammation and infection. I&D is necessary to relieve the pressure and drain the infected material, allowing antibiotics to work effectively.

**Option D (Medical Treatment):** While medical treatment, including antibiotics, is essential for managing acute dacryocystitis, I&D is crucial for addressing the acute inflammation and infection directly.

**Core Concept:** Acute dacryocystitis is typically caused by bacteria, which requires a combination of medical treatment (antibiotics) and surgical intervention (I&D) for effective management.

**Clinical Pearl:** Acute dacryocystitis is a type of orbital infection, and early surgical intervention is crucial to prevent complications such as orbital cellulitis or cavernous sinus thrombosis.

**Why the Correct Answer is Right:**

In the context of managing acute dacryocystitis, I&D (incision and drainage) is the preferred treatment option as it directly addresses the acute inflammation and infection present in the lacrimal sac. This surgical procedure relieves the pressure and allows the antibiotics to work effectively, ensuring better outcomes for the patient.

**Why Each Wrong Option is Incorrect:**

**Option A (Surgical Dacryocystorhinostomy - DCR):** DCR is used when the lacrimal sac is obstructed, but not inflamed and infected. I&D is necessary in acute dacryocystitis to address the infection and inflammation directly.

**Option B (Medical Treatment):** Antibiotics are essential components of the treatment plan for acute dacryocystitis, but they alone are not sufficient to cure the infection and inflammation. I&D is crucial to alleviate the pressure and allow antibiotics to work effectively, thus improving patient outcomes.

**Option D (Medical Treatment):** Similar to Option B, antibiotics are essential for managing acute dacryocystitis, but they alone are not sufficient to treat the infection and inflammation. I&D is necessary to relieve the pressure
