How the method works
The patient's blood is taken from a vein, it is centrifuged, and plasma with a high concentration of platelets is isolated. Platelets contain growth factors that stimulate the production of your own collagen and tissue renewal. Plasma is administered by microinjections into the skin of the periorbital area. Since the material is proprietary, the risk of allergies is virtually eliminated. The course usually consists of 3-4 procedures with an interval of 2-3 weeks, the result develops gradually over a month after the course.
Why is the drug injected into the eye?
The eye is separated from the general bloodstream by a blood-ophthalmic barrier: the medicine taken in tablets reaches the retina in a negligible concentration. Therefore, local administration is widely used in ophthalmology - drops, injections under the conjunctiva, parabulbar, retrobulbar and directly into the vitreous body.
The deeper the drug is injected, the higher the concentration in the desired area, but the stricter the requirements for sterility and technique.
Types of drug administration
- subconjunctival - under the mucous membrane of the eye
- parabulbar - in the tissue around the eyeball
- retrobulbar - behind the eyeball, closer to the optic nerve
- intravitreal - directly into the vitreous body
What is important for the patient to know
Injections are performed after instillation of anesthetic drops, so pain is minimal. A slight hemorrhage under the conjunctiva after an injection is a common and safe occurrence; it resolves in 1–2 weeks. You should consult a doctor if pain increases, vision decreases, and redness increases a day after the procedure.
