If left untreated, uveitis can progress to permanent vision loss. Complications of uveitis include cataracts, glaucoma, macular edema, and retinal detachment. With appropriate treatment, most attacks of anterior uveitis resolve within days to weeks, however, relapses are common. Inflammation related to posterior uveitis may last from months to years and may cause permanent vision damage, even with treatment.^{[1][2][3][4][5]}

If left untreated, uveitis can progress to permanent vision loss. Uveitis is estimated to be responsible for approximately 10% of the blindness in the western world.^[3][4][5]

Possible complications of uveitis include:^[6][7]

• Cataracts
• Glaucoma
• Macular edema
• Retinal detachment
• Synechia
• Vision loss

The prognosis of uveitis varies with the subtype, etiology, severity, duration and responsiveness to treatment.

• The following are favorable prognostic factors:^{[8][9][10][11][12][13][14][15][16][17]}
  
  • Rapid initiation of corticosteroid treatment
  • Good initial visual acuity
  • Good response to standard medical therapy

• The following are poor prognostic factors:^{[8][9][10][11][12][13][14][15][16][17]}
  
  • Chronic disease course
  • Posterior or intermediate uveitis
  • Lack of response to standard medical therapy
  • Complications of uveitis
  • Poor initial visual acuity
  • Isolated ocular uveitis (no underlying systemic disease)

With appropriate treatment, most attacks of anterior uveitis resolve within days to weeks, however, relapses are common. Inflammation related to posterior uveitis may last from months to years and may cause permanent vision damage, even with treatment.^[1][2]
