If the effect of injection treatment is not good, patients with macular edema can also be combined with oral drug therapy, such as heptaphyllum saponin sodium tablets, lecithin complexed iodine tablets, etc. to promote the absorption of macular edema. Macular edema is a common disease in ophthalmology, which can be induced by many reasons, such as diabetic retinopathy, retinal vein occlusion, macular degeneration, etc. At present, it is mainly treated by intravitreal injection, that is, injection of anti-neovascular drugs, such as compazine, abercrombie and fitch, which is one of the most effective means. If the effect of drug injection alone is not good, it can also be combined with oral drug therapy to promote the absorption of edema, such as hepatic saponin sodium tablets, lecithin complex iodine tablets and so on to enhance the efficacy of treatment. Specific medication should be under the guidance of a doctor. It is recommended that patients go to the ophthalmology department of a regular hospital and follow the doctor’s instructions.
