The doctor. Elvira, specialist of the ophthalmological clinic Oftalvist, explains what the procedure known as vitrectomy consists of, according to the doctor himself, a very effective but at the same time complicated treatment.
Vitreous surgery or vitrectomy is the surgical technique that consists of the approach of the posterior part of the eyeball, the retina and the vitreous. It is always performed under a surgical microscope , and usually with 3 access routes: one for the placement of the infusion system for the maintenance of constant eye pressure, and another used for the introduction of an endo-illumination probe. In general, we usually find a third way, in which a vitrectome or different instruments such as micropinzas or micro-scissors are introduced.
Vitrectomy is a technique that is performed if the patient has any of the following problems:
- Retina detachment
- Vitreous hemorrhage
- Macular hole
- Intraocular tumors
- Vitreomacular traction syndromes
Almost always done by inserting trocars , you can use accessory lights called torpedoes or "chandeliers". We also use infusion of serum, sometimes intraocular air or buffer mixtures for the postoperative period. And so a host of techniques that can be used, taking into account that always fits the pathology of each patient individualizing each case.
We must know at all times that we are facing the most sensitive part of the eyeball. The main risks of the intervention are that the visual recovery is less than expected, a retinal detachment in the postoperative period, vitreous hemorrhages or postsurgical macular edema .
Indications after vitreous surgery
The indications to follow by the patient once subjected to vitrectomy, which will depend on the specific case and the pathology that caused it. As a general rule, the patient is recommended to rest. It is also given a specific guideline for topical and sometimes oral treatment.
At the beginning of the postoperative period, vision is usually poor, recovering gradually over time. The patient must go to the office if, having recovered his vision, he again has severe visual loss, a symptom that something is not going well again. This must follow in any case the specific recommendations provided by the ophthalmologist.
