Vitrectomy for Retinal Detachment
Vitrectomy is currently the standard technique for treating
most retinal detachments. It involves creating 3 little holes
on the sclera (white of the eye) through which 3 different
instruments are put through. It allows for the removal of
the vitreous gel inside the eye, after which we identify where
the holes in the retina are. The holes are then treated with
either freezing treatment or laser. A bubble of gas is then
placed inside the eye to help push the retina in its place.
This bubble of gas is then gradually absorbed by the eye,
a process that takes some weeks. During this time the vision
will be very blurry. Occasionally, we have to use oil inside
the eye to help the retina stay in its place. The oil is then
removed after a few months, a process that requires another
operation. Sometimes we leave the oil in the eye, usually
when the surgeon feels that removing it may cause the retina
to detach again.
Following the operation drops are used for a few weeks to
reduce the inflammation in the eye. Regular post-operative
check-ups are required to ensure a good outcome.
Vitrectomy Surgery for Macular Holes
The only current treatment for macular holes is surgery called
vitrectomy, where the “gelly” (vitreous) inside
the eye and the very superficial layer of the retina (Internal
Limiting Membrane – ILM) are removed. A bubble of gas
is placed inside the eye that acts as a splint to close the
macular hole. The vision will be very blurred after the surgery
because of the gas inside the eye. This gas is gradually absorbed
by the eye, and when it disappears the vision usually improves.
Eye drops are required for a few weeks after the surgery the
reduce the inflammation in the eye. There is a 90-95% chance
of closure of the hole with this type of operation, and the
improvement in vision will depend on how long the hole has
been present.
Vitrectomy for Diabetic Retinopathy
– Vitreous Hemorrhage
Vitrectomy is the current standard technique for removal of
blood within the eye. There are numerous conditions that can
cause bleeding inside the eye, and by far the commonest is
Proliferative Diabetic Retinopathy. The technique consists
of creating 3 tiny holes on the sclera (white of the eye)
through which 3 different instruments are put through. This
allows for the removal of the vitreous gel and blood inside
the eye. Once the blood has been removed from inside the eye,
the cause of the bleeding is identified and treated. Scatter
laser is then applied to the retina, causing the bleeding
vessels to shrink and disappear. A bubble of air, gas or oil
in then put in the eye to prevent bleeding in the immediate
post-operative period. In the event that silicone oil is used,
it is usually removed a few months later once the condition
of the eye has stabilized.
After the surgery, drops are used routinely for a few weeks
to reduce the inflammation in the eye. Regular checks after
the operation are required to detect and treat any complications
that may arise.
