I am 4 weeks out from macular hole, membrane peeling and vitrectomy surgery. My surgical eye is still very red and inflammed. I am still on one drop of prednisone eye drops and one drop of atropine a day. The gas bubble is dissolving and I have vision above it, albeit cloudy and a little distorted. I told the surgeon at my 1 week check up that my surgical eye was itchy and she said that was normal and to use OTC comfort drops in that eye to soothe it. Before surgery, I had told the surgeon that I was allergic to thimerosal and could not have that in my eye drops. Could I also be allergic to the preservative in the prednisone and atropine? Or is it normal to still have a red and inflamed eye 4 weeks after surgery? It looks almost as bad today as it did on the day of surgery. I have many allergies, food and medicinal (antibiotics) included.
