Unique Features of Posterior Ocular Involvement of Whipple's Disease in a Patient with No Gastrointestinal Symptoms.

Purpose: To describe posterior ocular involvement features of Whipple's disease (WD) in a patient with no gastrointestinal symptoms.Methods: Retrospective case report.Observation: A 53-year-old man with a 2-year history of seronegative arthritis presented with bilateral intraocular inflammation, optic disc edema, and cystoid macular edema (CME) in the left eye. A diagnosis of noninfectious uveitis was made and oral prednisolone was started. Despite initial improvement, after 6 weeks, CME was found in both eyes. Because of the initial response, the anti-tumor necrosis factor agent Adalimumab was started. Twelve weeks after initiation of adalimumab, fundus examination revealed widespread dot-blot retinal hemorrhages and multifocal chorioretinal lesions at the posterior pole and mid-periphery. The chorioretinal lesions appeared as hyperreflective drusen-like deposits located in the sub-retinal pigment epithelium (RPE) space on the tomographic scan. WD was considered and confirmed by polymerase chain reaction test and duodenal biopsy.Conclusion: Posterior ocular involvement in WD may present with a wide clinical spectrum including intraocular inflammation and unique features of sub-RPE deposits, widespread retinal hemorrhages, and optic disc edema.
