Primary open-angle glaucoma requires attention to avoiding emotional stress, living a healthy lifestyle, taking medication as prescribed by the doctor, and monitoring intraocular pressure and blood pressure. 1. Avoiding emotional stress: Keeping a relaxed mood, anxiety, excitement, anger and other bad emotions will lead to fluctuations in intraocular pressure, which is not conducive to the recovery of the disease. 2. Healthy lifestyle: Take reasonable rest, avoid staying up late, and avoid aggravating the burden on the eyes by over-exerting the eyes. Exercise properly to improve immunity. Avoid eating spicy and greasy stimulating food, and eat more vitamin-rich fruits and vegetables. Avoid constipation and straining to defecate. 3. Use medication as prescribed by the doctor: strictly follow the doctor’s instructions to use Latanoprost Eye Drops, Travoprost Eye Drops and other intraocular pressure-lowering medications, and pay attention to eye hygiene. 4. Monitor intraocular pressure and blood pressure: Regularly monitor intraocular pressure and blood pressure to prevent the condition from deteriorating due to the rise in intraocular pressure caused by high blood pressure. It is recommended that patients go to the ophthalmology department of regular hospitals for consultation and follow the doctor’s instructions for treatment.
