Post-fever retinitis - Newer concepts

Area of Science:

• Ophthalmology
• Infectious Diseases

Background:

• Post-fever retinitis (PFR) is an infectious or para-infectious uveitic condition primarily observed in tropical regions.
• Clinical presentation alone often makes pinpointing the exact etiological agent challenging.
• Concurrent systemic symptoms like joint pain and skin rash are common during the febrile phase.

Purpose of the Study:

• To discuss the clinical features, pathogenesis, diagnostic investigations, and management strategies for Post-fever retinitis.
• To highlight the differential diagnosis based on potential bacterial or viral etiologies.
• To review current therapeutic approaches and the role of observation in PFR management.

Main Methods:

• Review of clinical presentations and diagnostic approaches for PFR.
• Analysis of etiological factors, including bacterial (e.g., rickettsia, typhoid) and viral (e.g., chikungunya, dengue, West Nile virus, Zika virus) agents.
• Discussion of treatment modalities, encompassing antibiotics, systemic steroids, and watchful waiting.

Main Results:

• Diagnosis of PFR etiology often requires serological investigations, PCR, and epidemiological context.
• Bacterial PFR typically responds to systemic antibiotics, potentially with steroids.
• Viral PFR management is primarily supportive with steroids, though observation is also advocated.

Conclusions:

• Accurate etiological diagnosis is crucial for effective Post-fever retinitis management.
• Treatment strategies for PFR vary significantly depending on whether the cause is bacterial or viral.
• Further research may elucidate optimal management pathways for different PFR subtypes.
