Hi, I have a cataract in my left eye. From one and half year. There is also a uveitis or inflammation in the eye. Doctor prescribed me combigan and diflusap 5 months ago. It improves my condition of elevated eye pressure very much. But 2 months ago my ocular pressure was 17 and now its raise to 23 and sometimes I see blackout of 8 to 10 sec. When I got up from bed or sitting. Today doctor prescribed me pred acetate, the substitute of diflusap. I want to know these complication is due medication. Or it is something else.
