  • Fractal Pattern of Chronic Serpiginous Choroiditis

    Jun 17 2025 by Guilherme Sturzeneker, MD, MSc

    Ultra-widefield fundus photograph and autofluorescence of a 33-year-old woman with longstanding serpiginous choroiditis in the right eye. The image reveals centrifugal chorioretinal atrophy forming a dramatic fractal-like pattern, sparing the fovea. The patient is several years post-onset, with repeated negative workups, including for tuberculosis. Despite extensive lesions, the patient retains 20/20 vision in both eyes. Management included azathioprine monotherapy, as systemic steroids were contraindicated due to bipolar disorder.

  • Choroidal Metastasis With Orange Pigment in a Patient With Endometrial Carcinoma

    Aug 8 2024 by Guilherme Sturzeneker, MD, MSc

    Ultra-widefield fundus photograph and autofluorescence of a 62-year-old woman with endometrial cancer, denoting choroidal metastasis with unusual orange pigment. This presentation is a reminder that the development of orange pigment is not pathognomonic for choroidal melanoma, as it may be seen in other lesions such as carcinoma metastasis.
