BACKGROUND: Although 8q21.11 microdeletion syndrome (8q21.11 DS) has been reported in association with congenital corneal opacities, reports of the clinicopathological features and management are scarce.
METHODS: We reviewed medical records including ophthalmic evaluations, imaging, operative reports, and pathology reports of two unrelated patients referred to the Ophthalmology Clinic of UPMC Children's Hospital of Pittsburgh with a cytogenetic diagnosis of 8q21.11 DS.
RESULTS: Ophthalmological evaluation of both children revealed bilateral enlarged, staphylomatous, and cloudy corneas with neovascularization. These findings were consistent with the diagnosis of congenital corneal staphyloma (CCS). In one patient, anterior segment optical coherence tomography and high-frequency ultrasound revealed materials consistent with lens remnants embedded in the cornea; this was confirmed by histopathology. In the second patient, lens was found to be adherent to the cornea during surgery. One eye underwent enucleation for corneal perforation secondary to elevated intraocular pressure. In the other eyes, treatment consisted of penetrating keratoplasty combined with vitrectomy. Ahmed tube was subsequently placed to control intraocular pressure.
CONCLUSION: 8q21.11 microdeletion syndrome can be associated with bilateral CCS, likely related to a combination of anterior segment developmental anomalies and elevated intraocular pressure. Tectonic penetrating keratoplasty is necessary to prevent corneal perforation, together with a strict control of the intraocular pressure.
