Reasons for Eye Surgery
Advanced Diabetic retinopathy
During diabetes, blood vessels can explode in the eye. Blood then pours into the vitreous, which must be removed by vitrectomy.Diabetic Retinopathy (DR) is a serious complication of Diabetes Mellitus (DS) that then reaches the retinal vessels and is due to chronic hyperglycemia.
It is a progressive disease that can therefore have adverse effects on vision if not treated early.
People with DS have a higher risk of developing R & D, since many times the DS can exist for a long time until diagnosis.
In addition, if the patient is diabetic or suffers from other problems such as hypertension, hypercholesterolemia , anemia , obesity or smoking , the risks increase even more.
The stages of R & D (ETDRS) are as follows:
- Nonproliferative diabetic retinopathy (minimal, moderate, severe and very severe): this is the first stage of the disease. This is an early stage of diabetic retinopathy, since vision is not affected yet. This stage is characterized by the presence of microaneurysms, exudates and haemorrhages and sometimes by macular edema.
- Proliferative diabetic retinopathy (uncomplicated and complicated): Due to the poor perfusion of the retina, some parts lack oxygen (ischemia). In response, the retina produces new vessels of poor quality.
All diabetics must perform an ophthalmological examination. R & D is usually asymptomatic in its infancy and vision can remain good, even if it evolves.
Patients with mild to moderate non-proliferative diabetic retinopathy should perform an ophthalmologic examination every 6-9 months, those with severe non-proliferative diabetic retinopathy every 3 months, while patients with proliferative advanced diabetic retinopathy require more frequent monitoring.
Pregnant women with diabetes mellitus must undergo ophthalmic examinations every 3 months.
Depending on the shape and size of the wounds of the eye, the main treatment methods are:
Laser photocoagulation : The laser destroys abnormal blood vessels and prevents the formation of new abnormal vessels.
Intravitreal injections : the most modern treatment of neovascularization and macular edema. The injection of anti-VEGF antibodies inhibits the activity of VEGF and thus the formation of abnormal vessels.
Vitrectomy : Surgical treatment of complicated proliferative DR.
The diabetic patient must check his blood glucose level, but also the other factors already mentioned. If the diagnosis of RD is made early and a treatment is set up quickly, the patient will be able to stop the progression of the disease.
The best treatment is prevention. Regular monitoring by an ophthalmologist is essential to protect your eyes!
The macula, in the center of the retina in the back of the eye, is the most precise area of our vision. When a hole forms in this macula, a dark spot appears in the center of our vision. A vitrectomy will be necessary to fill the hole.
Myodesopsy, the disease of floating bodies
Myodesopsy, the appearance of "floating bodies" or "flying flies", is an eye disorder characterized by the appearance in the field of vision of mobile stains, blackheads or filaments of various shape and opacity that seem suspended in the air during the movement of the eye.
Other diseases or operations require vitrectomy: retinal detachment, membrane problems, haemorrhages.
The glaze may be a gel, it can peel off the walls of the eye. The consequences are variable, with age the vitreous takes off in virtually everyone, but all do not have the same vision disorders. Given the risks of the operation, a vitrectomy to glue the vitreous is recommended only in extreme cases.
