Hi, Welcome to Healthcaremagic.com. I had gone through your question I can understand your concern about your husbands herpes zoster. As your husband is in recovery stage and it also seems to me according to your history that ophthalmic division was not primarily involved, so there are little chances at this stage to get another division involved. But if you feel the infection is there and eye is too much red associated with new fever and pain you need to visit an emergency room too. Hope my answer will help you and visit us back if you have any further questions. Regards Dr Muzaffer Hussain Parray.
