Retinal integrity in human babesiosis: a pilot study

Area of Science:

• Ophthalmology
• Infectious Diseases
• Parasitology

Background:

• Babesiosis, a tick-borne illness, has been anecdotally linked to eye complications.
• Previous research on ophthalmologic effects of babesiosis is limited to case reports and animal studies.
• The impact of babesiosis on retinal health in human patients remains largely uninvestigated.

Purpose of the Study:

• To investigate the presence of retinal abnormalities in patients diagnosed with acute babesiosis.
• To determine if retinopathy is a clinical feature of human babesiosis.

Main Methods:

• A cross-sectional descriptive pilot study was conducted.
• Ten patients with laboratory-confirmed babesiosis were enrolled from Yale New Haven Hospital.
• Retinal examinations were performed using indirect ophthalmoscopy following pupil dilation.

Main Results:

• Retinal examinations of ten babesiosis patients were generally unremarkable.
• No evidence of retinal inflammation, infection, bleeding, tears, or abnormal vessel formation was observed.
• The findings suggest babesiosis did not cause detectable retinopathy in this cohort.

Conclusions:

• This pilot study did not identify retinopathy in patients with babesiosis.
• Larger cohort studies with longitudinal follow-up are recommended.
• Further research is necessary to fully understand potential microvascular complications of babesiosis.
