Table 4.4. Pneumatic retinopexy technique steps<br />
Apply anesthetic of choice<br />
Prepare eye – povidone–iodine 5% – 5 min ¥2<br />
Prepare chosen gas<br />
Place eyelid speculum<br />
Perform cryopexy (one-step procedure)<br />
Paracentecis (surgeon’s choice)<br />
Position patient, head<br />
Caliper measurement – 4 mm<br />
Inject gas bubble/location<br />
Inspect gas location, central retinal artery perfusion<br />
Check intraocular pressure until normalizes<br />
Patch with arrow drawn<br />
Laser (next day, if two-step procedure)<br />
by topical, subconjunctival, peribulbar, or retrobulbar routes. A<br />
retrobulbar or parabulbar injection is given when cryopexy is<br />

for gas injection alone. The globe, eyelids, and periocular skin<br />
are prepared with a 5% povidone–iodine solution applied twice at<br />
5-min intervals. Some surgeons choose to add a topical antibiotic
