Summary

Ocular cat scratch disease, caused by Bartonella infection, commonly presents with retinal or choroidal lesions. Other posterior segment findings include optic disc swelling and macular stars, with visual acuity often preserved.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Medical Imaging

Background:

  • Cat scratch disease (CSD) is a bacterial infection caused by Bartonella henselae.
  • Ocular manifestations of CSD can affect the posterior segment, impacting vision.
  • Understanding these findings is crucial for timely diagnosis and management.

Purpose of the Study:

  • To evaluate the spectrum of posterior segment findings in ocular cat scratch disease.
  • To characterize the prevalence and nature of these findings.
  • To correlate findings with visual acuity outcomes.

Main Methods:

  • Retrospective case series.
  • Analysis of clinical and photographic records from 24 patients (35 eyes) over 6 years.
  • Review for specific posterior segment manifestations of Bartonella infection.

Main Results:

  • Discrete white retinal or choroidal lesions (50-3000 microm) were most common (83%).
  • Optic disc swelling (46%) and macular star (43%) were also frequent.
  • Vascular-occlusive events occurred in 14% of eyes, often near retinal lesions.

Conclusions:

  • Isolated retinitis or choroiditis foci are the most common posterior segment manifestation of CSD.
  • A diverse range of posterior segment findings can occur in ocular CSD.
  • Final visual acuity was generally good (≥20/25 in 74% of eyes).
