Patients with punctate inner chorioretinopathy mainly complain of dark shadows, flashing sensations, dark spots, blurred vision and decreased vision in front of one eye. It can also be seen as a result of lens and vitreous diseases. Punctate inner choroidopathy is a rare multifocal inflammatory disease of the choroidal retina that typically occurs in young women with myopia and presents as scattered yellowish-white lesions in the posterior pole at the level of the retinal pigment epithelium and inner choroid, with a self-limiting process that is usually not associated with inflammation of the anterior segment and vitreous. The pathogenesis of the disease is unknown. Some scholars have examined patients for antibodies against various pathogens, blood tests, serum angiotensin-converting enzyme, and antinuclear antibodies, and found no abnormalities, so it is thought that it may be a degenerative disease due to myopia. However, the patient presented with an inflammatory response, and it is difficult to explain the clinical presentation of the patient with a degenerative view. The disease may also be an autoimmune disorder. Most patients do not require treatment, but for those who present with a large number of macular punctate lesions, especially with plasmacytoid retinal detachment, treatment should be given The commonly used drug is glucocorticoid, usually prednisone is used in oral doses of 0.5 to 1 mg/(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 beyond 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.
