Hello doctor, I am 42 years, male. Before 10 months, I was diagnosed with acute posterior uveitis- Chorioretinitis with macular edema in my right eye. I received an intraocular injection with a corticosteroid and was treated with Clindamycin for two weeks, without having any evidence of actual cause. Took long list of blood tests and nothing suspicious. I got a resolution of the macular edema after about three mouths and was having inflammation only around the nerve till a week ago when my uveitis started to worsening rapidly three weeks after periocular injection with Triamcinolone (my first periocular injection) and I am almost 100 % sure that the injection caused the acute re-inflammation. I have read that for ocular toxoplasmosis is extremely risky a preciocular injection with Triamcinolone to be applied, but post-factum. My vision is currently very poor, not able to read with the right eye and before two days, I was able to. I am scared and not sure what to do. I know that in acute situations intraocular injections of corticosteroid is applied, but not sure how my eye will react to it this time. Is there a way to lower the effect or duration of the applied Triamcinolone? Is its duration of activity 3 to 4 weeks or three months?
Hello. Sorry to hear about your condition and wish you quick recovery. Triamcinolone periocular injections are used in extreme situations and should be under the coverage of antibiotics, which usually are at least two groups, at the time of the injection and should be done under extreme caution. However, you mentioned that all the laboratory results came in negative and macular edema is rarely a finding in chorioretinitis. In order to better evaluate your condition and advise you properly please upload all the OCT scans that were done, the lab test results, ophthalmologist examination before and after the procedure.
