Tubercular Retinal Vasculitis: Diagnostic Dilemma and Management Strategies

Area of Science:

• Ophthalmology
• Infectious Diseases
• Public Health

Background:

• Ocular tuberculosis (OTB) is an uncommon extrapulmonary manifestation of systemic tuberculosis (TB).
• Tubercular retinal vasculitis (TRV) is a frequent and specific presentation of OTB, yet its diagnostic criteria and optimal management remain unclear.
• Accurate diagnosis and treatment of TRV are challenging due to its rarity and varied clinical presentation.

Purpose of the Study:

• To provide a practical, evidence-based approach for the diagnosis and management of tubercular retinal vasculitis (TRV).
• To synthesize current literature and expert consensus on suspecting, investigating, and diagnosing TRV.
• To guide appropriate treatment strategies for TRV, considering ethnic and geographic factors.

Main Methods:

• Comprehensive literature review of conventional and modern diagnostic investigations for OTB and TRV.
• Analysis of existing evidence and consensus statements regarding the clinical profile of TRV.
• Evaluation of the rationale and utility of antitubercular therapy and corticosteroids for TRV.

Main Results:

• TRV is a significant cause of uveitis, particularly in TB-endemic regions.
• Diagnostic certainty for TRV remains challenging, necessitating a combination of clinical suspicion and targeted investigations.
• The optimal duration and necessity of antitubercular treatment, as well as the role of corticosteroids, require further clarification.

Conclusions:

• A structured, evidence-based approach is crucial for the accurate diagnosis of TRV.
• Management strategies for TRV should integrate clinical findings with available diagnostic data.
• Further research is needed to establish definitive treatment guidelines for TRV, addressing the uncertainties surrounding antitubercular therapy and corticosteroid use.
