Topic 7 — Uveitis: Classification, Evaluation & Management
A rapid synthesis connecting the site of inflammation with symptoms, examination findings, investigations, treatment decisions and important visual complications.
Prepared according to the supplied AIM Concept Integration structure. :contentReference[oaicite:0]{index=0}
1. THE TOPIC IN ONE CONNECTED FLOW
Uveitis is best understood by first identifying where the inflammation is centered. The anatomical site determines the dominant symptom pattern and examination findings. These findings then guide targeted investigations, help distinguish infectious from non-infectious disease, and direct treatment aimed at controlling inflammation while preventing irreversible visual loss.
Cause / Trigger
Immune-mediated, infectious, traumatic or idiopathic
→
Uveal Inflammation
Iris/ciliary body or choroid/retina involved
→
Barrier Breakdown
Cells, protein and inflammatory debris enter ocular compartments
→
Clinical Pattern
Anterior: pain, photophobia, ciliary redness
Posterior: floaters, visual loss, little redness
→
Diagnostic Clue
Anterior: cells, flare, KPs, synechiae
Posterior: vitritis, retinitis, choroiditis
→
Management
Control inflammation and treat the underlying cause
→
Outcome / Complication
Synechiae, glaucoma, cataract, macular or retinal damage

3. AIM HIGH-YIELD INTEGRATION REVIEW
⭐ Anatomical localization → symptom pattern: anterior inflammation causes pain and photophobia, while posterior inflammation more commonly causes floaters and visual loss.
⭐ Blood-aqueous barrier breakdown → cells and flare: leukocytes produce cells, while leaked protein produces flare on slit-lamp examination.
Inflamed iris → posterior synechiae: adhesion of iris to lens produces an irregular pupil and may contribute to secondary pressure problems.
Posterior inflammation → vitreous or retinal disturbance: vitritis produces floaters, while macular involvement causes marked central visual reduction.
⭐ Clinical phenotype → targeted workup: slit-lamp and fundus findings guide selective testing for systemic inflammatory or infectious causes.
Macular symptoms → OCT: retinal thickening or fluid on OCT confirms inflammatory macular edema as a cause of central visual loss.
⭐ Cause determines therapy: non-infectious inflammation may require corticosteroids, whereas infectious disease requires organism-directed treatment.
AIM Exam Trap: A granulomatous appearance such as large “mutton-fat” keratic precipitates suggests an inflammatory pattern, but it does not by itself identify the exact underlying disease.
