Symptoms of punctate inner chorioretinopathy, patients mainly complain of dark shadows in front of one eye, flash sensation, dark spots, blurred vision and decreased visual acuity, visual acuity loss is mostly mild (above 0.5), some patients may have severe visual acuity loss (can be down to 0.04), no eye redness, eye pain and other manifestations, no concomitant systemic diseases. Typical changes are multiple scattered yellow-white circular lesions, 50-300 μm in size, in the fundus bilaterally, located at the level of the retinal pigment epithelium and inner choroid, mainly concentrated in the posterior pole, and some lesions may be accompanied by placoid retinal detachment. Some lesions may be accompanied by plasmacytoid retinal detachment. These lesions usually resolve after several months, leaving behind either retinal pigment epithelial disorder or an atrophic choroidal retinal scar, which later becomes a scar with chisel-like edges. What should be done to prevent and treat black shadows in front of one eye? Most patients do not need treatment, but for a large number of macular punctate lesions, especially with placental retinal detachment, treatment should be given to the commonly used drugs for glucocorticoids, generally choose prednisone oral dose of 0.5-1mg/(kg-d). For subretinal neovascularization, there are three treatment methods: ① oral treatment with prednisone can delay the growth of subretinal neovascularization and even make it recede in some patients, so this treatment is especially suitable for subretinal neovascularization in the macula; ② laser photocoagulation is mainly used for neovascularization outside 200 μm in the avascular area of the central macula, and this treatment can make the neovascularization recede; ③ laser photocoagulation is mainly used for subretinal neovascularization in the subretinal area. (3) submacular neovascularization peeling has a better effect, but more clinical cases and longer observation are needed to confirm this treatment. Punctate inner chorioretinopathy is generally a self-limiting disease, rarely recurring, and most patients have a good prognosis of 0.5 or more, but subretinal neovascularization often affects the patient’s vision.
