Endogenous uveitis: an analysis of 1,417 cases

Area of Science:

• Ophthalmology
• Immunology
• Retrospective Cohort Studies

Background:

• Uveitis represents a significant cause of ocular inflammation and vision impairment.
• Understanding the changing patterns and etiological factors of uveitis is crucial for effective management.
• Previous studies by the same author in 1978 and 1985 provide a historical baseline for comparison.

Purpose of the Study:

• To determine the occurrence of various forms of uveitis in a large patient cohort.
• To analyze trends and changes in uveitis patterns over the past 25 years.
• To identify the most common etiological agents and associated systemic diseases in uveitis patients.

Main Methods:

• Retrospective analysis of 1,417 uveitic patients referred to a specialized Ocular Immunovirology Service.
• Comparison of current data with previous studies from 1978 and 1985 conducted at the same institution.
• Statistical analysis to assess changes in incidence and diagnostic categories over time.

Main Results:

• Anterior uveitis was the most frequent type (49.12%).
• Intermediate uveitis showed a significant increasing incidence (p < 0.0001).
• Idiopathic uveitis decreased significantly (from 56.8% to 38.1%, p < 0.0001), alongside an increase in specific diagnoses like pars planitis and Fuchs' heterochromic iridocyclitis.
• Toxoplasma gondii was the most common infectious agent (6.63%), and Behçet's disease was the most frequent associated systemic disease (6% of patients with systemic disease).

Conclusions:

• Ocular inflammation patterns are evolving, with a notable rise in intermediate uveitis.
• Improved diagnostic capabilities have reduced the proportion of idiopathic uveitis cases.
• Identifying specific etiological agents and associated systemic conditions remains critical for comprehensive uveitis management.
