ABSTRACT To investigate the therapeutic procedures and their efficiencies for the treatment of congenital microphthalmos during or after the developing period.
It was a retrospective case series study. Eighteen cases with congenital microphthalmos, aged less than 12 years, underwent self inflating osmotic hydrogel expanders. Among them, 11 cases were treated by implantation with sphere self-inflating hydrogel expanders into the retrobulbar space and 5 cases had implantations into the conjunctival socket. The remaining 2 cases were treated with implantation of injectable self-inflating hydrogel pellet expanders. Twenty eight cases with congenital microphthalmos, aged more than 12 years, accompanied with other deformities, were treated with proper reconstruction surgery. Fourteen cases were treated with medial canthoplasty, 12 cases were treated with medial and lateral canthoplasty, 3 cases were treated with ptosis correction and medial or lateral canthoplasty and 2 cases with socket reconstruction. T-test was used for the comparison between groups.
Sixteen cases obtained satisfactory results without any complications. In one case, the hydrogel expanders migrated inferiorly in the orbit and underwent adjustment. In another case, although the hydrogel expander prolapsed from the socket, the socket was still expanded. In the developing period, the length of palpebral fissure was (15.83 ± 1.87) mm before the operation, and that made much wider after the operation (18.67 ± 1.74) mm. There were statistically significant differences between them (t = -4.029, P = 0.01). The height of palpebral fissure was (1.33 ± 0.67) mm and (6.00 ± 0.58) mm before and after the operation, respectively, which were statistically significant (t = -5.813, P = 0.00). Patients who aged more than 12 years and underwent eyelids and eye socket reconstruction, also obtained satisfactory appearance.
Patients with congenital microphthalmos could obtain the development of orbit and satisfactory appearance by reconstruction treatment according to different period of development.
