Background: New techniques adapted for vitrectomy surgery, including t
he use of silicone oil and perfluorocarbon liquids, have been applied
very successfully to giant retinal tears. Most surgeons thus turn imme
diately to vitrectomy for all giant tears. The authors have found that
patients with giant tears usually have such rapid flow of fluid from
the vitreous to the aqueous that repeated paracenteses can be performe
d without shallowing the anterior chamber, thus allowing injection of
sufficient gas into the vitreous cavity to unroll and tamponade the gi
ant tear without the need for vitrectomy. This makes pneumatic retinop
exy a feasible alternative for those selected fresh giant tears that h
ave mobile flaps and extend less than 180 degrees. Methods: Five conse
cutive patients with giant retinal tears were treated with pneumatic r
etinopexy using paracentesis and two or more gas injections. They were
followed at least 2 years. Results: Four of the five tears were succe
ssfully reattached, although a new tear developed in one, and scleral
buckling surgery was performed 11 months after the pneumatic retinopex
y. Conclusion: The authors conclude that pneumatic retinopexy is a rea
sonable alternative for selected patients with giant retinal tears.
