Pneumatic Retinopexy – for selected types of small detachments with holes in the upper retina, the retina can be reattached with a combination of a gas bubble and either laser or Cryotherapy. The bubble is designed to hold the edges of the retina together so it heals, just like a plaster cast holds the edges of a broken bone together.ģ. Retinal detachment is when the retina pulls away from the tissue around it (the choroid), which supplies it with oxygen and nutrients. After this procedure you will need to keep your head down, to allow the bubble to close the hole. What follows is a pictorial, instructive guide depicting and describing various types of retinal holes and tears, their possible etiologies and management strategies.
PARTIALLY TORN RETINA FULL
The eye is then filled with a bubble of a special gas, heavy liquid or silicone oil. Retinal defects come in different shapes and sizes and may be either partial or full thickness. The retina is fixed in position using laser treatment. Preparation Risks Outlook What is retinal detachment Retinal detachment is a serious condition of the eye in which the retina stops receiving oxygen. Vitrectomy – this is a microsurgical “keyhole” operation using 3 tiny instruments which remove the jelly from inside the eye and any scar tissue which has developed. Sometimes a gas bubble is also injected into the eye.Ģ.
The retina is fixed back in position with Cryotherapy, or freezing treatment. This pushes the outer wall of the eye inwards and helps close the hole in the retina. Freezing the tissue causes a formation of scar tissue that holds the retina to the eye wall. Your natural eye fluid may seep through that hole and build up behind the retina. Then, a freezing probe is placed directly over the tear on the outer surface of the eye. A retinal detachment often starts with a small tear or hole in the retina. Scleral Buckle – in this procedure, a tiny silicone band is placed around the eye like a belt. Treatment for a partial retinal tear might include: Cryopexy (Freezing): This method starts with local anesthetic so the eye is numb. There are 3 ways to treat a retinal detachment.ġ.
