Summary
Dengue fever can cause permanent vision loss due to retinal capillary occlusion. Early ophthalmoscopy is crucial for severe Dengue cases to detect ocular abnormalities.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Vascular Medicine
Background:
- Dengue fever is a mosquito-borne viral infection with diverse clinical manifestations.
- Ocular complications of Dengue fever are uncommon but can be severe.
Observation:
- A case report detailing a patient with Dengue fever who experienced permanent bilateral visual loss.
- Clinical examination revealed retinal hemorrhages, cotton wool spots, and vascular sheathing.
- Fluorescein angiography demonstrated macular and equatorial capillary nonperfusion.
Findings:
- The patient's Dengue fever diagnosis was confirmed via serology for IgM antibodies.
- Retinal capillary occlusion was identified as the cause of permanent visual impairment.
- The ocular findings were consistent with severe Dengue-related retinopathy.
Implications:
- This case highlights the potential for severe ocular complications, including permanent vision loss, from Dengue fever.
- Ophthalmoscopy is recommended for patients presenting with severe Dengue to identify and manage potential ocular involvement.
- Early detection and intervention may be critical in preventing irreversible visual damage in Dengue patients.
