Homide and atropine sulphate ointment is helpful in releasing the symptoms. Betnesol-N contains betamethasone, a steroid that reduces the inflammation. It s not clear from the description, what was the reason for posterior uveitis. Homide and atropine ointment should be usually taken only till the symptoms persist. Betnesol-N should be taken as instructed only. Long term use of steroids are not usually desirable. Please do take the drugs for the prescribed duration only. Have a regular follow up with your ophthalmologist after that. Hope the above information helps you. Thanks you very much for writing into healthcaremagic.
