Thank you very much for your prompt response. I will definately seek out a corneal and external eye disease subspecialist ASAP. I will also look in to the possibility of damage to the non-arteric ischemic optic neuropathy. I must point out, that I have read a vast amount of testimonies that describe one of the side effects of cialis, the ED drug in question, as bloodshot eyes. I have also read a great deal about the possibility of dependency and rebound from prednisolone. Since I had no preexisting condition before I took the medications, and have not been found to have any underlying condition through my doctor visits since I have been prescribed these medications, I really don't think it can be from anything else but the cialis, or prednisolone. I've gone through the a few comprehensive medical eye examinations, the dry eye tests, and have not been found to have anything abnormal w/ eyelids or hyperthyroidism. I am a relatively young, healthy, non smoker, and I have been blessed with low blood pressure. I have had a few medical professionals tell me the same thing you are, that it can't be from the presnisolone or cialis, but I feel I have narrowed it down to the only possibilities through the process of elimination. I greatly appreciate your input, and will most definately keep the forum updated as to the findings of an external eye disease subspecialist. What a wonderful tool this forum is as another resource in the vast world of healthcare advice.
Medications for erectile disfunction (ED) do not cause conjunctivitis. They have been associated with "blue vision" while they are in the blood but that is a temporary problem. There is a possible link with damage to the optic nerve (non-arteritic ischemic optic neuropathy). However this link is not definitely established and has almost always occured in men with risk factors for this problem (advanced age, high blood pressure, diabetes, smoking, etc).
Your present problems are not due to the ED medicine and are not due to the prednisolone. Prednisolone is a potent anti-inflmmatory that would make almost any type of conjunctivitis better. Moreover this medication is rapidly cleared from the body in eyedrop form and could in no way persist causing problems after a week off the medication.
There are many cause of chronic conjunctititis and many things that simulate chronic conjunctivitis that are not chronic conjunctivitis (example dry eyes, eyelid abnormalities, hyperthyroidism for example).
You need to see an ophthalmologist for a comprehensive medical eye examination (look for the MD after his/her name). If you live in a large or even middle size community, you might consider a corneal and external eye disease subspecialist. This type of ophthalmologist is sometimes in private practice and most medical school, department of ophthalmology have such a specialist.
