Hi Atanu Ghosh,
The management of glaucoma
is quiet a challenging one and it differs between ophthalmologists. If your ophthalmologist has been treating your father for the past two years he would have monitored the eye pressure ,the condition of the optic nerve
and the retinal nerve fibres, the visual field
damage during his reviews.
And the decision to do combined surgery counts on a number of factors like
- The stage of glaucoma and it's control with topical medications .
- The target eye pressure ,as decided by your ophthalmologist.
- The general health of the patient and his age( to avoid multiple visits for surgical intervention) ESP in your father being a cardiac pt.
- the post op inflammation and recovery time should also be kept in mind.
- the combined surgery controls the eye pressure better and SOMETIMES reduces or eliminates the need of topical medication.
So,considering all this , I think you should go ahead with a combined surgery as per your ophthalmologist.
Hope this helps.
