PURPOSE: To evaluate the use of orbital polyacrylamide gel injection for the correction of anophthalmic enophthalmos. METHODS: Noncontrolled clinical trial of 21 patients (14 with ocular implants, 5 with phthisis bulbi, and 2 with dermis-fat graft). Orbital CT was performed to estimate the volume of polyacrylamide gel needed to restore orbital volume. Polyacrylamide gel was injected using a 22-gauge (30 x 0.7 mm) needle transcutaneously inserted in the lateral third of the lower eyelid, directed to the orbital muscle cone. A second injection was administered 15 days later, if necessary. CT was repeated 30 days after the last procedure. Exophthalmometry was performed before and 90 days after the procedure. RESULTS: The mean total volume injected per orbit was 2.4 +/- 0.7 ml (range, 1-3.5 ml). The volume of the enophthalmic orbit increased from 26.9 +/- 5.0 ml to 29.3 +/- 4.9 ml (p < 0.001). The mean difference in exophthalmometry readings was 3.3 +/- 1.6 mm (range, 1.5-8.0 mm) before the procedure and 1.0 +/- 0.9 mm (range, 0.0-3.0 mm) after 3 months (p < 0.001). Adjustment of the ocular prosthesis or fabrication of a new one was necessary in 11 patients (52.4%), and the mean volume of the ocular prosthesis was reduced from 2.0 +/- 0.6 ml to 1.6 +/- 0.6 ml (p = 0.003). All patients were satisfied with the aesthetic results. No serious adverse events were observed. The initial results were maintained 1 year after the procedure. CONCLUSIONS: Polyacrylamide gel injection in the orbital space effectively reduces enophthalmos in ocular prosthesis wearers.
