Autofluorescence imaging in rubella retinopathy.

Area of Science:

• Ophthalmology
• Retinal Imaging
• Infectious Disease Complications

Background:

• Rubella retinopathy (RR) is a potential complication of congenital or acquired rubella infection.
• Accurate diagnosis of RR is crucial for appropriate patient management.
• Traditional diagnostic methods may be invasive or lack sensitivity to early retinal changes.

Observation:

• Four patients with sensorineural hearing loss underwent comprehensive ophthalmic examinations.
• Fundus autofluorescence (FAF) imaging, electroretinogram (ERG) testing, and fluorescein angiography (FA) were utilized.
• FAF imaging was performed on both eyes of all participants.

Findings:

• Salt-and-pepper retinopathy, indicative of RR, was observed in seven eyes.
• FAF imaging revealed characteristic stippled fluorescence in all affected eyes, highlighting retinal pigment epithelium disturbances.
• Electroretinogram (ERG) tests demonstrated normal retinal function, suggesting FAF's superior sensitivity to subtle RPE changes.
• Fluorescein angiography (FA) identified choroidal neovascularization in one patient.

Implications:

• Fundus autofluorescence (FAF) imaging serves as a sensitive and noninvasive tool for diagnosing rubella retinopathy (RR).
• FAF can detect early retinal pigment epithelium alterations associated with rubella infection.
• This imaging modality can assist clinicians in establishing the diagnosis of RR, especially when other tests are normal.
