A 68-year-old man with high myopia presents with sudden onset of floaters, photopsia, and a shadow in the superior nasal field of his left eye. Visual acuity is 6/60. Fundoscopy shows a large superior nasal retinal detachment with the macula already involved. The patient is otherwise healthy with no systemic comorbidities. What is the most appropriate immediate management?

Explanation

## Clinical Scenario Analysis This patient presents with a **macula-off retinal detachment** (vision 6/60 indicates macular involvement) with a large superior nasal break. This represents a **surgical emergency** requiring same-day or next-morning intervention. ## Urgency Classification | Feature | Macula-On RD | Macula-Off RD | |---------|-------------|---------------| | Visual Acuity | ≥6/12 | <6/60 | | Timeline | Urgent (within 24 hrs) | **Emergency (same day/next morning)** | | Anatomical Status | Macula attached | **Macula detached** | | Risk of PVR | Moderate | High | | Surgical Approach | Scleral buckle or vitrectomy | Often vitrectomy preferred | **Key Point:** Macula-off RD is a **true surgical emergency**. Every hour of delay increases the risk of permanent vision loss and proliferative vitreoretinopathy (PVR). ## Management Decision Tree ```mermaid flowchart TD A[Retinal Detachment Confirmed]:::outcome --> B{Macula Status?}:::decision B -->|Macula-On| C[Urgent surgery within 24 hrs]:::action B -->|Macula-Off| D[Emergency intervention ASAP]:::urgent D --> E{Large/Complex RD?}:::decision E -->|Yes| F[Vitrectomy preferred]:::action E -->|No| G[Scleral buckle option]:::action F --> H[Admit for same-day/next-morning surgery]:::urgent G --> H ``` **High-Yield:** The **large superior nasal break** in this patient suggests a high risk of proliferative vitreoretinopathy (PVR) and requires **vitrectomy** rather than scleral buckle, as vitrectomy allows better visualization and management of vitreous traction. **Clinical Pearl:** In macula-off RD, the first 6–24 hours are critical. Studies show that surgery performed within 24 hours has better anatomical and functional outcomes compared to delayed surgery. The patient should be admitted immediately for same-day or next-morning surgical intervention. ## Why Vitrectomy Under General Anaesthesia 1. **Large detachment** requires comprehensive vitreous examination and management 2. **Macula-off status** demands maximum visualization and precision 3. **General anaesthesia** allows longer operative time and better patient cooperation 4. **Vitrectomy** permits removal of vitreous traction and management of PVR risk **Tip:** In NEET PG, remember: **Macula-off = Emergency same-day surgery**. Do not delay with investigations or conservative management.
