Chikungunya infection can cause ocular issues like iridocyclitis and retinitis, which typically resolve well with treatment. This study highlights these common eye complications and their generally favorable outcomes.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Virology
Background:
- Chikungunya is a mosquito-borne viral illness known for causing fever and joint pain.
- Ocular manifestations of chikungunya infection are not widely reported, necessitating further investigation.
Purpose of the Study:
- To document and characterize the spectrum of ocular manifestations in patients with chikungunya infection.
- To assess the clinical course and visual outcomes of chikungunya-associated ocular diseases.
Main Methods:
- A retrospective, observational case series involving nine patients with confirmed chikungunya infection and ocular complaints.
- Ophthalmic examinations included fundus photography, fluorescein angiography, and optical coherence tomography.
- Ocular lesions were recorded and analyzed for frequency and location.
Main Results:
- Nine patients presented with ocular lesions, including nodular episcleritis (1), acute iridocyclitis (5), and retinitis (3).
- Ocular symptoms appeared 4–12 weeks after initial fever.
- Retinal changes were consistent with viral retinitis; iridocyclitis lacked specific diagnostic features.
- All patients achieved good visual recovery following treatment.
Conclusions:
- Iridocyclitis and retinitis are the most common ocular manifestations of chikungunya, typically presenting a benign clinical course.
- Episcleritis is a less frequent ocular finding.
- Chikungunya-associated ocular changes should be considered in the differential diagnosis of viral retinitis and iridocyclitis in affected regions.
