I am writing to you concerning my 3-year-old male budgie who has been experiencing vision problems lately. I am hoping you can offer some insight into what might be causing this issue.
Currently, my budgie is under meloxicam treatment, which he has been taking for ten days. I also want to inform you that last year around September, he gained weight on a pellet diet, his weight was reaching up to 50 grams. He had fats under his belly and his cloaca was darker possibly indicating intestins being crushed. However, we managed to help him lose weight with daily exercises, and he has been stabilized around 40 grams since January this year, with a small dip to 37 grams last month.
I, myself, had a fungal infection around December 2022, which was treated with ketoconazole. Although I took utmost care to wash my hands before touching my birds, I may have forgotten once or twice.
My budgie had a sort of conjunctivitis around his right eye two month ago in January, which went away under three days with a single rinse of pure saline water, and there was a very small scratch on the top part of his eyelid. Recently, he has developed a gradual loss of vision, which is concerning to me.
I have already seen two specialized veterinarians, who have both checked him and do not know the cause of his vision loss, because there are no visible damage in they eye membranes. They think it might be neurological and do not believe that he has or has had any bacterial or fungal infection, as he has no other symptoms except for the vision problem. Because i feel like i am never doing enough and kept worrying so I kept insisting and asking whether it might be a bacterial or a fungal infection. The vet wrote a prescription with baytril and voriconazole, stating "Here is the prescription that can reassure you. I unfortunately do not think he has any infection"
So, my question is, is there any case of a budgie developing vision problems due to a fungal infection without showing any respiratory or any other symptoms or distress?
I would be grateful if you could provide me with your opinion and advice on what I should do next to help my budgie. I look forward to hearing back from you soon.
Thank you for your time and attention.
