Reconstruction strategy in isolated complete Cryptophthalmos: a case series

BACKGROUND: The present study sought to introduce clinical characteristics and stepwise surgical strategies of isolated complete cryptophthalmos, a rare, congenital ocular anomaly. CASE PRESENTATION: Retrospective, noncomparative, clinical study. Six patients with isolated complete cryptophthalmos were diagnosed at the Beijing Tongren Hospital between 2010 to 2018. The presentation age of patients ranged from 1 month to 68 years. This study includes two males and four females, and involvement was noted to be bilateral in two cases and unilateral in four cases. According to orbital CT scan and ocular CDI results, two patients were combined with ocular cyst. Reconstruction surgeries were performed in three patients, involving the eyeball enucleation, creation of fornix, eyelid reconstruction with skin flaps/amniotic membrane, and implantation of prosthesis. Besides, implantation of hydroxyapatite was performed in one pediatric patient to promote orbit development. Good outcomes in terms of cosmetic satisfaction were achieved in all patients during follow-up. CONCLUSIONS: Surgical intervention could only improve the cosmetic appearance in isolated complete cryptophthalmos. The surgical strategies may be planned to use three-stage approaches described in this study. Meanwhile, orbital development must be taken into consideration in pediatric cases.
