    The use of anterior segment optical coherence tomography in evaluation of punctal stenosisL’utilisation de l’OCT-SA dans la sténose du point lacrymal

    Purpose To evaluate the applicability of anterior segment optical coherence tomography (AS-OCT) for objective diagnosis of punctal stenosis. Methods We report the use of AS-OCT in 3 cases of epiphora related to punctal stenosis. We followed the methodology described in previous studies. The examination was performed by a single technician using a single Spectralis OCT with the AS-OCT module. Three patients with complaints of epiphora (mean age = 80 years) were examined. The external punctal diameter was measured on both infrared (IR) and OCT images. The internal diameter was measured on OCT images at a depth of 500 μm. The diagnosis ...
