Hi Preeti, Thanks for writing in to Healthcare Magic! The Wysolone is a steroid called Prednisolone and has got many side effects but at times is very beneficial in certain diseases. Whether it would lead to any benefit will depend on what is causing the vision loss. Please get the proper and thorough check up of the eye for vision loss. If an Ophthalmologist does not find any local cause then it may be something more serious in the brain and you should get him examined by an experienced physician. The side effects of steroid can be Cushing s syndrome and growth retardation in childn; osteoporosis, fractures. Peptic ulceration; glaucoma, cataracts; hyperglycaemia, pancreatitis; increased appetite, obesity. Topical: Thinning and atrophy, systemic absorption with prolonged use over large surface, broken skin or under occlusive dressing. Rash, allergic reactions, pruritus.
