A wavy sensation when looking at a straight line is a manifestation of visual distortion, which is usually seen in macular diseases, such as macular anterior membrane, macular fissure, macular edema or macular hemorrhage, all of which may cause visual distortion. After this symptom appears, you should first go to the hospital to improve the fundus examination, especially the macula area should be examined in detail by optical coherence tomography. If macular edema is present, intraocular injection of Ativan can be used to reduce the macular edema. If there is neovascularization in the macular area, intraocular injection of rezumab injection and abciximab injection can be given to promote the regression of neovascularization and to inhibit the production of new neovascularization. If it is macular anterior membrane or macular fissure, surgery is usually required.
