Objective:
To describe a case of inflammatory pigment epithelial detachment (PED)
presumed to be secondary to the amoeba Blastocystis hominis.
Methods:
This is an interventional case report.
Results:
A 46-year-old male complained of visual distortion in the left eye for 7
months. Examination revealed the presence of a subretinal cystic lesion on
the fovea. Optical coherence tomography demonstrated a PED with a
hyperreflective lesion over the detached retinal pigment epithelium (RPE).
Work-up included a fecalysis, which revealed the presence of Blastocystis hominis.
The patient was treated with oral metronidazole. RPE detachment resolved
after treatment with no recurrence in 30 months of follow-up.
Conclusion
Intestinal parasitic infection may be associated with retinal disease and
should be included in the differential diagnosis of PED when OCT reveals a
hyperreflective lesion.
