Q: My mother has gone through cataract surgery in the left eye. The second day after the surgery, when the bandage was removed, she could not see through the centre portion of the eye. She only had vision from the corners of the eye. The doctor said that there is vitreous haemorrhage. After waiting for vitreous haemorrhage clearance for two months (as told by doctor) the eye was examined after partial clearance of blood. The doctor said that there is a macular hole with slight retinal detachment (FFA, OCT done). The doctor suggested vitrectomy, which is complicated surgery with chances of severe side effects. What is the success rate of the surgery? How much sight will recover through this? What will be the side effects? Should we go for the surgery or not? Will the condition of the eye remain the same or deteriorate further, if we do not opt for surgery?

A:Macular hole surgery has 80-90% anatomical success but functional or visual success is unpredictable and depends on the duration of the hole.
