Macular cystoid edema is a sign caused by disease, some can be cured, while some patients can only control and slow down the development, not completely cured, the specific prognosis is related to the patient’s condition. Macular cystoid edema is usually caused by some eye diseases, such as central retinal vein obstruction, idiopathic choroidal neovascularization, wet age-related macular degeneration, diabetic retinopathy, etc., which leads to distortion of vision or vision loss. For treatment, intravitreal injection of anti-neovascular drugs, such as Compazine, Ranibizumab, etc., can be taken, and some patients can be cured, but some patients’ conditions are more difficult to recover. For example, macular cystoid edema caused by severe idiopathic choroidal neovascularization, wet age-related macular degeneration or diabetic retinopathy is more difficult to treat. Through treatment, the patient’s condition can be controlled or slowed down, but it is easy to recur and cannot be completely cured. It is recommended that patients with macular cystoid edema should consult the hospital in time to assess their condition and follow the doctor’s instructions for treatment.
