Vitrectomy is an operation to remove the vitreous
gel from inside the eye. The reason for vitrectomy surgery depends on the cause for needing surgery.
One of the common causes for needing vitrectomy is if there are bothersome floaters
that’s affecting your daily quality of life. So, vitrectomy is then done to remove all
the floaters to relief one’s symptoms. Sometimes surgery is also done for underlying retinal
problems that could potentially lead to loss of sight. So conditions such as retinal detachment,
in macula hole and epiretinal membrane bleeding in the eye or vitreous haemorrhage from diabetes,
so those are some of the reasons for needing eye surgery or retinal surgery more specifically
and the first step of retinal surgery is always to remove the vitreous first and that is where
vitrectomy comes in to first remove the vitreous to then allow me to safely access the retina
to provide treatment for the rest of the retina. We don’t actually need our normal vitreous
anyway in the eye. Here’s an interesting fact for you and the vitreous is only required
when we are growing in our mother’s womb for development of the eye. After birth the vitreous
actually serves no function. The vitreous space, once the vitreous has been removed
is filled by fluid that the eye normally produces called aqueous humour that maintains eye pressure.
Those are some of the reasons why somebody may require vitrectomy.
