There are more types of glaucoma that are more difficult to treat, such as long-term medication type, treatment failure type, adolescent type, neovascular type, etc. There is no such thing as which type of glaucoma is the most difficult to treat, and the specific treatment effect is related to the patient’s condition. 1. Long-term use of drugs: If the patient’s glaucoma is relatively long, the long-term use of drugs to control, may lead to a decrease in the sensitivity of the drug, increasing the difficulty of treatment. 2. Treatment failure type: If the patient’s glaucoma fails after surgical treatment, the intraocular pressure rises again, which will lead to the aggravation of the patient’s condition and is generally not easy to treat. 3. Adolescent type: As the onset of the disease is related to heredity, the elasticity of the patient’s eyeball wall tissues will gradually weaken, and symptoms such as increased intraocular pressure will occur, making the treatment more difficult accordingly. 4. Neovascular type: In addition to the basic symptoms of glaucoma, this disease is accompanied by neovascularization at the angle of the eye, which is a kind of intractable glaucoma. It is recommended that glaucoma patients should consult a doctor in time to evaluate their condition and follow the doctor’s instructions.
