title: Familial Incomplete Punctal Canalization: Clinical and Fourier Domain Optical Coherence Tomography Features.
abstract: Incomplete punctal canalization is a form of punctal dysgenesis with membranous noncanalization and can be confused with punctal agenesis. The clinical and diagnostic features are known; however, familial incomplete punctal canalization has not been reported earlier. A family with 3 affected members is presented in this series with similar incomplete punctal canalization and nasolacrimal duct obstructions. After membranotomy and endoscopic dacryocystorhinostomy with bicanalicular intubation, all of them are free of epiphora at last visit.
