Redness and watering in eyes. Vision!

My mother is 69 years old. She has been experiencing continuous watering from her eyes throughout the day, along with mild redness and blurred vision,She consulted a local ophthalmologist and was prescribed Pixelub Multi, FML-T, and Relief Get 50% for one month. Her symptoms have improved by approximately 50%, but watering, redness, and some blurriness are still present. She also has a history of persistent tinnitus, for which she has consulted several doctors without significant improvement. She sometimes feels uneasy/uncomfortable when her stomach is empty. She is also taking medication for high blood pressure. Please advise whether further eye examination or tests are required, particularly for dry eye, blocked tear duct, cataract, eye pressure/glaucoma, or any other cause of the watering and blurred vision
