• Inflammation of the iris and ciliary body
• Clinical features:

• Reduced visual acuity
• On examination:
• Pupil may be small and irregular (due to posterior synechiae - adhesions of iris to the lens)
• On using slit lamp, anterior chamber may show:
– cells (moving, white specks)
– hypopyon - pus in anterior chamber
– flare (looking through frosted glass)
• keratic precipitates may be seen at the back of the cornea
