+## 6. Clinical Abbreviations & Diagnostic Codebook (临床病种缩写与全称速查手册)
+Many ophthalmic datasets adopt hospital-specific, short-hand abbreviations that can cause severe diagnostic ambiguity if misinterpreted. Below is the authoritative clinical dictionary aligned with the codebase (`class_labels_zh.py`, `trhd59_taxonomy.csv`, and `trhd66_clinical_abbreviations.csv`).
+### A. Critical Clinical Disambiguation & Avoidance of Misnomers (核心消歧与避坑指南)
+> [!IMPORTANT]
+> **Key Disambiguation Rules**:
+> 1. **`PMM_CNV` = 特发性息肉状脉络膜血管病变 (Polypoidal Choroidal Vasculopathy / PCV)**
+>    *Misconception*: Frequently mistaken for "Pathologic Myopia with CNV".
+>    *Ground Truth*: In this cohort, `PMM_CNV` strictly represents **PCV**. True myopic CNV is separately encoded as **`PM_CNV`** (高度近视性脉络膜新生血管).
+> 2. **`COC` = 先天性大视杯 (Congenital Large Optic Cup)**
+>    *Misconception*: Mistaken for Choroidal Osteoma (脉络膜骨瘤) or glaucomatous cupping.
+>    *Ground Truth*: Codebase explicitly documents: *"COC must not be interpreted as choroidal osteoma"*. It represents physiological large optic cup with normal, pink neuroretinal rim obeying the ISNT rule.
+> 3. **`TC` vs `TR`: 外伤性脉络膜视网膜病变 vs 外伤性视网膜病变**
+>    *Misconception*: `TC` mistaken for Toxocariasis (眼弓蛔虫病).
+>    *Ground Truth*: In this project, `TC` = **Traumatic Chorioretinopathy** (外伤性脉络膜视网膜病变, deeper choroidal involvement with pigmentary scarring); `TR` = **Traumatic Retinopathy** (外伤性视网膜病变, retinal contusion/Purtscher-like cotton wool spots).
+> 4. **`EMM` vs `ERM`: 黄斑膜前膜 vs 视网膜前膜**
+>    *Ground Truth*: `EMM` is strictly restricted to the **foveal/macular area** (Epiretinal Macular Membrane), whereas `ERM` represents generalized **Epiretinal Membrane** across the posterior pole.
+> 5. **`SOD` = 小视盘 / 视隔-视神经发育不良 (Small Optic Disc / Septo-Optic Dysplasia)**
+>    *Ground Truth*: Represents severe optic nerve hypoplasia, linked with de Morsier syndrome (midline septum pellucidum absence).
+> 6. **`PR` = 视网膜静脉周围炎 (Periphlebitis Retinae / Eales Disease)**
+>    *Misconception*: Mistaken for Retinal Detachment or prolapse.
+>    *Ground Truth*: Represents vascular periphlebitis with characteristic perivenous sheathing and recurrent vitreous hemorrhages in young adults.
+> 7. **`SO eye` = 硅油填充眼 (Silicone Oil Filled Eye)**
+>    *Misconception*: Mistaken for Sympathetic Ophthalmia.
+>    *Ground Truth*: Iatrogenic post-vitrectomy status showing hyper-reflective silicone oil reflex and meniscus droplets.
+> 8. **`PLS` = 激光光凝斑 (Retinal Laser Spots)**, **`PM` = 视盘前膜 (Prepapillary Membrane)**, and **`VO` = 玻璃体混浊 (Vitreous Opacity)**: None of these represent Pathological Myopia or Vein Occlusion.
