My 10 +yr old cat had a terrible bout of histoplasmosis in 2005-2006. She lost sight in her right eye. The vet I had been seeing has moved away and I don't know of any others. Every once in a while her other "not so blind" eye will get real bloody. I have used prednilisone drops, but after reading internet reports, have stopped it because it in itself can supposedly cause blindness. I have treated her initially and occasionally since with Sporonax, an anitfungal medicine, but it is very costly and I can't tell if it actually helps. It must have helped with her overall condition in 2006, but these sporadic bloody eye episodes are confusing to me. I am not sure if the histoplasmosis remains in the system for years. She seems to be eating fairly well, but doesn't move about much -sleeps mostly. I have 3 other cats, one in particular tends to tease and chase her which may or may not have a bearing on this matter.
