A 38-year-old man with a history of chronic epiphora and recurrent episodes of medial canthal swelling over the past 2 years presents with acute onset of fever (38.5°C), severe pain over the medial canthus, and purulent discharge. He has already completed two courses of oral antibiotics in the past 6 months without sustained relief. On examination, there is a tender, fluctuant mass medial to the medial canthus, and gentle pressure expresses pus from the lacrimal punctum. What is the most appropriate next step in management?

Explanation

## Management of Acute Dacryocystitis with Abscess Formation ### Clinical Context: Acute Abscess Requiring Immediate Drainage **Key Point:** This patient presents with a **fluctuant, tender mass** with pus expressible from the lacrimal punctum — this is an acute dacryocystitis abscess. The **most appropriate next step** is immediate incision and drainage (I&D) to relieve the acute infection, decompress the abscess, and prevent spread (e.g., orbital cellulitis). DCR is the definitive long-term treatment but is contraindicated in the setting of active acute infection. **High-Yield:** The standard teaching (Khurana, Yanoff & Duker) is that acute dacryocystitis with abscess formation requires **I&D first**, followed by DCR after the acute infection has fully resolved (typically 4–6 weeks later). Performing DCR through infected, inflamed tissue risks wound breakdown, anastomotic failure, and spread of infection. ### Why Immediate I&D Is the Correct Next Step | Clinical Feature | Implication | |-----------------|-------------| | **Fluctuant mass** | Abscess has formed — requires drainage | | **Fever 38.5°C** | Systemic signs of infection | | **Failed 2 antibiotic courses** | Antibiotics alone insufficient | | **Active acute infection** | DCR contraindicated until infection resolves | **Clinical Pearl:** The management sequence for recurrent dacryocystitis with acute abscess is: 1. **Acute phase:** I&D + systemic antibiotics (IV if severe) 2. **Quiescent phase (4–6 weeks later):** DCR for definitive cure This two-stage approach is well-established in ophthalmic surgery (Khurana 6e, Ch 5; Yanoff & Duker Ophthalmology 5e, Ch 5.2). ### Why Other Options Are Suboptimal **Option A (Repeat oral antibiotics + warm compresses):** This patient has already failed two antibiotic courses. With a fluctuant abscess, antibiotics alone cannot drain the collection and will not prevent progression or complications. **Option C (Nasolacrimal duct probing):** Probing is effective for congenital nasolacrimal duct obstruction in infants (membranous obstruction). In adults, obstruction is fibrotic/anatomical and probing is ineffective. Moreover, probing through an acutely infected system risks spreading infection. **Option D (DCR):** DCR is the **definitive** treatment for recurrent dacryocystitis due to nasolacrimal duct obstruction, but it must be performed **electively after the acute infection has resolved**. Operating through acutely infected tissue significantly increases the risk of surgical failure and complications. DCR is the correct answer for "definitive management" but NOT for "most appropriate next step" in the acute setting. **High-Yield:** The question asks for the **next step** — in the presence of a fluctuant abscess with systemic signs, I&D is the immediate priority. DCR follows electively. [cite: Khurana AK, Comprehensive Ophthalmology 6e, Ch 5; Yanoff & Duker Ophthalmology 5e Ch 5.2; Wills Eye Manual 7e]
