Hi... Thanks for the query.. Are you diabetic/hypertensive? You might be having a cardiovascular problem.. Get yourself checked up with a physician first and later depending on the requirement you may consult a cardiologist.. Glaucoma medications as rightly told by you should not be stopped in between as it may cause slow progressive loss of vision.. The glaucoma medications will not cause any systemic side effects.. If you are not comfortable with the present medications you can inform to your ophthalmologist who can change the medications if it is feasible.. Don t worry... Keep continuing all the medications and have positive thought always.. You can get one MRI scan done to rule out MS.. Hope this information helps you..Take care.. Will be available for further queries..
