| Slide | Content |
|---|---|
| 1 | Title slide with topic index |
| 2 | Definition, normal Hertel values by race (Asian 18mm / White 20mm / Black 22mm), orbital anatomy, key distinctions (axial vs non-axial, pseudo-proptosis, enophthalmos) |
| 3 | Etiology in 6 color-coded categories - Thyroid/Endocrine, Inflammatory/Autoimmune, Primary Neoplastic, Secondary/Metastatic, Infectious/Vascular, Structural |
| 4 | Chandler Classification I-V (orbital cellulitis) + CAS scoring (7-item initial, 10-item follow-up) + EUGOGO severity (Mild/Moderate-Severe/Sight-threatening) |
| 5 | Systematic clinical examination - history framework, Hertel technique, globe displacement patterns, TED lid signs (Dalrymple/von Graefe/Kocher/Stellwag), with clinical photo |
| 6 | Clinical photos - symmetrical vs asymmetrical proptosis, bacterial keratitis from exposure, soft tissue involvement (chemosis, SLK), TED pearls |
| 7 | Investigations - bloods (TFTs, TRAb, ANCA, ACE), CT orbit indications, MRI orbit indications, special investigations |
| 8 | Management algorithm - Emergency (cellulitis → IV abx, Chandler staging, mucormycosis → amphotericin), TED (mild → selenium; moderate-severe → IV methylprednisolone + mycophenolate; teprotumumab), Neoplastic |
| 9 | Surgical sequence (Decompression → Strabismus → Lid surgery → Blepharoplasty, INACTIVE phase only), decompression techniques (1-wall through 3-wall, expected mm reduction), indications and complications |
| 10 | High-yield exam facts (15 #1 facts), mnemonics (IMSLOW, VISA, EUGOGO), unilateral vs bilateral differentials, urgent referral criteria |
| 11 | Master summary table - 9 diagnoses × 6 columns (onset, laterality, key features, investigations, treatment) |
