Acute posterior multifocal placoid pigment epitheliopathy and granulomatous uveitis following influenza vaccination

AbstractPurposeTo report a case of acute placoid multifocal posterior pigment epitheliopathy (APMPPE) following influenza vaccination. The patient exhibited granulomatous uveitis during the recovery phase.ObservationsA woman in her thirties developed flu-like symptoms seven days after receiving an influenza vaccination. Approximately 2 weeks later, the patient reported with conjunctival injection, blurred vision, and pain in her left eye. She was examined in our clinic, and the best-corrected visual acuity was 20/15 OD and 20/20 OS. Multiple whitish spots were observed bilaterally in the deep retinal layer along with edema of the left optic disc. Both indocyanine green and fluorescein angiographic findings suggested a diagnosis of APMPPE. Although APMPPE lesions were gradually resolved after one month, keratic precipitates, anterior chamber and vitreous cellular infiltration, iris and angle nodules, and macular edema were observed and were treated with topical steroid eye drops. No systemic disorders including sarcoidosis, tuberculosis, and Wegener's granulomatosis were present.Conclusion and importanceAs influenza vaccinations are administered worldwide, ophthalmologists should be aware of the ocular side effects following vaccination. Although rare, the possibility of APMPPE occurrence following influenza vaccination should be considered; additionally, the recovery phase of APMPPE may be associated with granulomatous uveitis that requires steroid therapy
