Vitreoretinal surgery

Vitreoretinal surgeryis a large family of various interventions involving the vitreous cavity and retina. This includes surgeries for: complications of cataract (1), retinal detachment (2), the macula (macular pucker or epiretinal membrane, macular hole, ...) (3), venous thrombosis and diabetic retinopathy (4), eye injuries (5), and intraocular infection (endophthalmitis) (6) among others.

1. During cataract surgery, complications can occur, regardless of the expertise of your surgeon, often resulting from weaknesses/ocular malformations that are difficult to predict in advance. Whether following a rupture of the posterior lens capsule with loss of a fragment or following a postoperative infection, it may be necessary to re-operate your eye to settle the situation.

2. A retinal detachment is related, in most cases, to the appearance of a hole in the retina through which the vitreous fluid will accumulate under the retina. Treatment involves surgery to reattach the retina to its support (different techniques exist and one of them will be selected depending on your case). This surgery is successful in first-line in more than 90%, but one patient being different to another, some retinas heal less well or re-detach several times. In all cases, flashes of light +/- floaters +/- dark grey cloud in your visual field should lead you to consult a specialist as soon as possible.

3. Macular surgeries (macular hole, macular pucker) consist in performing a vitrectomy (cleaning of the vitreous cavity) and removing a small membrane that compromise the vision in the macular area (part of the retina that is dedicated to the central vision). Visual recovery depends on various factors; the main ones being the duration of the presence of this membrane upon the macula and the causes responsible for its appearance.

4. As part of a thrombosis of a vessel of the retina (central vein or branch vein occlusion) or a diabetic condition affecting the retina, vitrectomy may be needed to clean-out the vitreous cavity and treat your retina (peeling proliferative vitreo-retinopathy (PVR), retinal laser, ...).

5. In an eye injury, surgery may be necessary to close that eye and treat various problems resulting from this injury (retinal detachment surgery, iris, retinal inflammation (PVR) or other).

6. During an infection, endophthalmitis or intraocular surgery is often necessary urgently to clean-out the vitreous cavity of proliferating germs (usually bacteria) before the retina (the organ of vision) is attacked.

In all these circumstances, different surgical techniques may be necessary (vitrectomy, scleral buckling, or pneumo-retinopexy) to address the problem. Depending on the degree of advancement or complexity of your illness and your healing ability, good visual recovery may be compromised.

Always remember that trust is gold and so do not hesitate to ask any questions related to your surgery before the operation.

A patient who does not understand is a surgeon who fails to make himself understood!
