Manifestation and grading of ocular involvement in patients with Tessier number 10 clefts.

PurposeThe objective of this study is to evaluate and grade the extent and severity of ocular involvement in Tessier number 10 cleft.Patients and methodsA retrospective, noncomparative, interventional case series was conducted between January 2006 and December 2015. Clinical data were reviewed from 59 patients (85 eyes) with Tessier number 10 clefts. Detailed medical history and ophthalmic examination of patients with a confirmed diagnosis of Tessier number 10 cleft were recorded on an itemized data collection form. Ocular manifestations were categorized as upper eyelid defect, symblepharon with cutaneous pterygium (skin growing onto the globe), corneal complications, and lower eyelid ectropion; components were evaluated and graded on a scale from 0 to 3, according to their severity.ResultsMore than half of the cases (43 eyes, 53.8%) had severe upper eyelid defect, and severe symblepharon with cutaneous pterygium were observed in 38 eyes (47.5%). Nearly half of the cases (40 eyes, 50.0%) have severe corneal complications, and lower eyelid ectropion was found in 34 eyes (42.5%). The severity of symblepharon, corneal complications, and lower eyelid ectropion were significantly correlated with the upper eyelid defect; the correlation coefficient (r) ranged from 0.844 to 0.629 (P<0.0001).ConclusionThis study presents the ocular manifestation of Tessier number 10 clefts with large-series cases, and establishes an effective grading system to evaluate Tessier number 10 clefts, which is useful for the diagnosis, treatment, and prediction of outcomes in patients with a Tessier number 10 cleft.
