We measured the outer punctal diameter (OPD), recorded the visibility of the internal punctum and punctal depth (PD) using AS-OCT, before and 1 month after treatment with preservative free methylprednisolone 5% eye drops. Punctal diameter, tear meniscus height (TMH) and Munk’s score were compared to the control group before and after treatment.Results: The mean OPD of the PEG before treatment (455.5 ± 174 μm) was significantly smaller than that of the CG (590.9 ± 106.6 μm) (P= 0.002). The mean OPD of the PEG significantly increased to 484.6 ± 175.5 μm after treatment (P < 0.001). Also, the visibility of vertical canaliculus lumen and PD were restored in 70% of eyes. The TMH was much higher in the PEG than in the CG before treatment (P< 0.05). However, after treatment the difference was not statistically significant.Conclusion: AS-OCT parameters were useful in monitoring and measuring the efficacy of medical treatment in relieving punctal edema, which subsequently resulted in reducing the epiphora symptoms.Keywords: AS-OCT, punctal occlusion, punctal edema, preservative-free steroidsElshorbagy MSShalaby OEEldesouky MAAwara AMDove Medical Pressarticleas-octpunctal occlusionpunctal edemapreservative free steroidsOphthalmologyRE1-994ENClinical Ophthalmology, Vol Volume 14, Pp 1467-1472 (2020)
