Evaluation of the lacrimal punctum parameters in Turkish population with anterior segment optic coherence tomography

To determine the anatomical parameters of puncta in Turkish population without any complaint of epiphora, using anterior segment optic coherence tomography (AS-OCT).

The healthy participants between 26 and 83 years old who applied to our outpatient clinic from May 2022 to June 2022 for spectacle prescription or the accompanying person of the patients were included in the study. All participants underwent AS-OCT (Revo 60, OPTOPOL Technology, Zawiercie, Poland).

This study included 105 eyes of 53 healthy participants, 27 (54 eyes) of the patients were male and 26 (51 eyes) of them were female with a mean age of 55.6 years (SD: 14.8, Range: 26-83 years). The mean external punctum width and internal punctum width values were 509.1 ± 101.5 μm (222-788 μm) and 229.2 ± 69.2 μm (108-459 μm), respectively. The mean value for vertical canaliculi depth was 637.8 ± 167 μm (337-1045 μm).

OCT is a non-invasive and objective diagnostic method in the clinical diagnosis and treatment of punctal lesions and provides useful information in terms of visualizing the punctum and vertical canaliculus supplying anatomical data.
