| ## 📘 Overview |
|
|
| **PALM (Pathologic Myopia)** is a publicly available fundus image dataset developed for detecting **pathologic myopia (PM)** and analyzing associated retinal lesions and anatomical structures. |
|
|
| It was released for the **Pathologic Myopia Challenge (PALM)**, hosted by the **Chinese Academy of Sciences** and **Sun Yat-sen University**, and published on **IEEE DataPort**. |
| The dataset provides both **classification** and **segmentation** tasks, making it valuable for multi-task ophthalmic AI research. |

| ## 🩸 Labels and Annotations |
|
|
| - **Classification Label:** |
| - `1` = Pathologic Myopia (PM) |
| - `0` = Non-Pathologic (Normal) |
|
|
| - **Segmentation Annotations:** |
| - Optic disc boundaries |
| - Fovea coordinates |
| - Lesion masks for: |
| - Patchy atrophy |
| - Retinal detachment |

|
| ## 🧠 Research Applications |
|
|
| PALM is designed for: |
|
|
| - **Pathologic Myopia detection** from fundus images |
| - **Segmentation** of optic disc, fovea, and lesion regions |
| - **Multi-task learning** combining classification and segmentation |
| - **Explainable AI** studies on high-myopia pathology |
|

|
|
| ## ⚙️ Limitations |
|
|
| - Limited image count (~1,200) |
| - Variability in camera type and illumination |
| - Binary labeling (PM vs Non-PM) does not cover all clinical myopia subtypes |
| - Lesion annotations may need preprocessing for some segmentation frameworks |
