Summary
Optical coherence tomography angiography revealed capillary nonperfusion in a patient with rickettsial retinitis. This noninvasive imaging technique is valuable for detecting occlusive complications in rickettsial retinitis.
Area of Science:
- Ophthalmology
- Infectious Diseases
- Medical Imaging
Background:
- Rickettsial infections can cause ocular manifestations, including retinitis.
- Early diagnosis and monitoring of rickettsial retinitis are crucial for effective treatment and visual preservation.
Observation:
- A 29-year-old male presented with acute blurred vision due to Rickettsia conorii infection.
- Ocular examination revealed retinitis with hemorrhages, edema, and serous retinal detachment.
Findings:
- Optical coherence tomography angiography (OCTA) demonstrated capillary nonperfusion in superficial and deep capillary plexuses.
- Fluorescein angiography confirmed retinal vascular leakage and nonperfusion post-treatment.
- Spectral-domain OCT showed retinal atrophy, cysts, and disruption of photoreceptor layers.
Implications:
- OCTA is a valuable noninvasive tool for assessing vascular complications in rickettsial retinitis.
- Findings highlight the potential for residual visual field defects despite treatment.
- This case underscores the importance of advanced imaging in managing infectious retinitis.
