Abstract
ABSTRACT Background The TUBB3 gene has been reported to be associated with type 3 congenital fibrosis of the extraocular muscles (CFEOM). The clinical features of CFEOM3 that are linked to TUBB3 mutations are diverse, ranging from mild ptosis and limitation of extraocular movement to severe ocular motility problems and central nervous system abnormalities. Materials and Methods This was a single retrospective case report. Result This case report describes a patient with infantile esotropia, who had a heterozygous variant in TUBB3 c.904 G > A (p.A302T) known to cause CFEOM3 and her family members, who presented with manifestations associated with CFEOM3. Conclusion Given the diverse clinical features of CFEOM3, the possibility of the occurrence of CFEOM3 should be considered when there is a congenital abnormality of extraocular muscle movement and a positive family history.
