Retinal Detachment
Objective
In cases of detachment of the retina from the choroid. The detachment is corrected:
• By cryotherapy
• By indenting sclera
• By encircling the sclera.
Position
Supine.
Anesthesia
Local, retrobulbar and facial nerve injection.
Procedure
1. It may be necessary to divide a rectus muscle to gain access to a retinal break.
2. By indirect ophthalmoscope the operator visualizes the site of the retinal break.
3. A cryoprobe is applied until the tissues around the retinal break are treated.
4. Explant is fixed to the sclera over the site of the retinal break.
5. To create an indent and achieve mechanical block of retinal breaks.
6. A silicone strap is passed under the four recti muscles.
7. The strap is overlapped and secured in the silicone sleeve. Usually done with cryotherapy.
