With prolonged use of steroid drugs, the following can be observed:
- increased intraocular pressure with possible subsequent development of steroid glaucoma with damage to the optic nerve and the visual fields (therefore, when using preparations containing glucocorticosteroids for more than 10 days, the intraocular pressure should be measured regularly);
- formation of posterior subcapsular cataract;
- slowing down the process of wound healing (with diseases that cause thinning of the cornea, its perforation is possible).
Allergic reactions are possible.
Secondary bacterial infection may occur as a consequence of suppression of the protective reaction of the patient's body. In acute purulent diseases of the eye, glucocorticosteroids can mask or strengthen the existing infectious process.
Fungal infection of the cornea tends to occur especially often with prolonged use of steroids. The appearance of non-healing ulcers on the cornea after prolonged treatment with steroid preparations may indicate the development of fungal infestation.
