Punctate inner choroidopathy

Punctate inner choroidopathy (PIC) is a relatively uncommon inflammatory multifocal chorioretinopathy that affects predominantly young myopic women. It is characterized by the presence of multiple, small, well-defined, yellow-white fundus lesions frequently limited to the posterior pole in the absence of flare and inflammatory cells in the anterior chamber or vitreous cavity. Most patients with PIC do not require treatment, as the disease does not often threaten vision; however, when subfoveal choroidal neovascular membrane (CNV) ensues, patients usually lose sight rapidly, requiring immediate care. Treatment modalities that have been used to manage patients with PIC and subfoveal CNV include systemic and local steroids, other immunosuppressant agents, laser photocoagulation, photodynamic therapy, submacular surgery and, most recently, anti-vascular endothelial growth factor therapy. To date, however, there is no clear consensus on the effective therapy. Further research into this area, as well as on the cause and possible predisposing factors for PIC, is warranted.
