Topic 7 — Uveitis: Classification, Evaluation & Management
High-yield memory reinforcement for rapid revision of classification, clinical clues, investigations, management and sight-threatening complications.
Structured according to the supplied AIM Student Memory Support requirements. :contentReference[oaicite:0]{index=0}
1. High-Yield Flashcards
Tap each question to reveal the answer.
What structures form the uveal tract?
Iris, ciliary body and choroid.
How is uveitis classified anatomically?
Anterior, intermediate, posterior and panuveitis.
Which symptom pattern strongly suggests anterior uveitis?
Pain, photophobia, blurred vision and circumcorneal redness.
What do anterior chamber cells represent?
Inflammatory leukocytes circulating in the aqueous humor.
What causes flare in anterior uveitis?
Protein leakage into aqueous after breakdown of the blood-aqueous barrier.
What are keratic precipitates?
Inflammatory-cell deposits on the corneal endothelium.
What does an irregular pupil suggest in anterior uveitis?
Posterior synechiae between the iris and anterior lens capsule.
Which symptoms favor posterior rather than isolated anterior uveitis?
Floaters and reduced vision with relatively little external redness.
What is vitritis?
Inflammatory cells and haze within the vitreous.
Which investigation is especially useful for uveitic macular edema?
Optical coherence tomography (OCT).
Which investigation can demonstrate retinal vascular leakage?
Fundus fluorescein angiography.
Why are cycloplegic-mydriatic drugs useful in anterior uveitis?
They reduce painful ciliary spasm and help prevent or limit posterior synechiae.
What is the key treatment principle before suppressing posterior uveitis?
Determine whether the inflammation is infectious or non-infectious.
Which major complications can cause visual loss in uveitis?
Posterior synechiae, secondary glaucoma, cataract, macular edema and retinal damage.
2. Mnemonics
Mnemonic Title: Anatomical Classification
AIPP
Meaning: Anterior → Intermediate → Posterior → Panuveitis.
Mnemonic Title: Anterior Uveitis Recognition
PCR
Meaning: Pain → Ciliary redness → photophobia with Reduced vision.
Mnemonic Title: Anterior Chamber Recognition
CFKS
Meaning: Cells → Flare → Keratic precipitates → posterior Synechiae.
3. Memory Tables
Anterior vs Posterior Uveitis
| Feature | Anterior | Posterior |
|---|---|---|
| Main symptoms | Pain, photophobia | Floaters, visual loss |
| Redness | Ciliary injection | Mild or absent |
| Key examination | Slit lamp | Dilated fundus examination |
| Typical findings | Cells, flare, KPs, synechiae | Vitritis, retinitis, choroiditis |
Important Investigation Connections
| Clinical Need | Investigation | Key Information |
|---|---|---|
| Anterior inflammation | Slit lamp | Cells, flare, KPs |
| Macular involvement | OCT | Retinal thickening or edema |
| Retinal vascular leakage | FFA | Vascular leakage / vasculitis |
| Fundus obscured | Ocular ultrasound | Posterior-segment assessment |
4. Rapid Revision Points — Last-Minute Revision
Must Remember:
- Anatomical localization is the foundation of uveitis classification.
- Anterior uveitis commonly presents with pain, photophobia and ciliary injection.
- Cells indicate leukocytes; flare indicates protein leakage into aqueous.
- Posterior synechiae can produce an irregular pupil.
- Large greasy keratic precipitates suggest a granulomatous inflammatory pattern.
- Posterior uveitis commonly produces floaters and reduced vision with little external redness.
- Macular involvement can markedly reduce central visual acuity.
- Uveitis workup should be targeted according to ocular pattern and systemic clues.
- Topical corticosteroids are important for non-infectious anterior inflammation; cycloplegics reduce pain and synechiae risk.
- Suspected infectious posterior uveitis requires cause-directed treatment and urgent specialist assessment.
KMU Exam Trap: Granulomatous-looking keratic precipitates suggest a pattern of inflammation; they do not identify a specific cause by themselves.
5. Clinical Memory Hooks
Painful photophobic red eye
→
think anterior uveal inflammation and look for cells and flare.
→

Floaters + reduced vision + minimal redness
→
think posterior involvement and examine the fundus.
→

Irregular pupil during anterior uveitis
→
posterior synechiae between iris and lens.

posterior synechiae between iris and lens.
Central visual distortion in posterior uveitis

6. ⭐ Starred High-Yield Exam Points
- ⭐ Anterior chamber cells + flare → breakdown of the blood-aqueous barrier.
- ⭐ Pain + photophobia + ciliary injection → classic anterior uveitis pattern.
- ⭐ Floaters + visual loss with little redness → posterior uveitis should be suspected.
- ⭐ OCT → key investigation for inflammatory macular edema.
- ⭐ Cycloplegic-mydriatic therapy → relieves ciliary spasm and helps prevent posterior synechiae.
- ⭐ Infectious versus non-infectious distinction → critical before definitive treatment of posterior uveitis.
