Congenital microphthalmos with orbital cysts: distinct diagnostic features and management

Abstract

Purpose: To review the clinical features and treatment strategies for microphthalmic globes with orbital cyst.

Methods: : The clinical records of 23 patients treated for microphthalmos associated with orbital cysts were reviewed retrospectively.

Results: Most cases of congenital microphthalmos with orbital cysts were first noted at birth, and all were confirmed by means of computed tomography and/or ultrasonography. Six of the 23 cases were bilateral. Sixty-seven percent of bilateral and 29% of unilateral cases also had other congenital malformations. Mild microphthalmos was noted in 3 orbits, moderate in 16 orbits, and severe in 10 orbits. On the basis of clinical findings, 8 orbits were treated with enucleation and cyst excision and 15 were treated with cyst excision only. Cyst aspiration was performed on 5 orbits; 2 required aspiration and subsequent cyst excision. Twenty-six orbits had good cosmesis and 2 had acceptable cosmesis. The mean follow-up interval was 5.15 years.

Conclusions: Management of microphthalmos with orbital cyst is a cosmetic issue. Cyst size, degree of microphthalmos, and general condition of the patient determine the best treatment approach.
