“…It has been postulated that this higher failure rate in older patients is due to a weak orbicularis muscle affecting the lacrimal pump 12 .Recent studies have demonstrated compromise of the facial nerve with external DCR incisions, which may further affect the lacrimal pump. 14 An advantage of an endoscopic DCR is the potential decreased risk to these branches of the facial nerve.…”

Objective To determine the preference for dacryocystorhinostomy (DCR), patient selection criteria for endoscopic DCR, endoscopic DCR technique, and barriers to adoption of endoscopic DCR. Method Cross-sectional study conducted from May-December 2021. A survey was sent to oculoplastic surgeons. Questions on demographic characteristics, type of clinical practice, technique preferences, barriers and facilitators to adoption of endoscopic DCR were included. Results 245 participants completed the survey. Most respondents were located at an urban site (84%), were in private practice (66%), and had been in practice for more than 10 years (58.9%). Sixty one percent perform external DCR as the first line procedure for treating primary nasolacrimal duct obstruction. The most common factor influencing the surgeon's decision to perform endoscopic DCR was the patient's request (37%) followed by endonasal exam (32%). The most common barrier for not performing endoscopic DCR was the lack of experience and lack of training during fellowship (42%). The most worrisome complication for most respondents was failure of the procedure (48%), followed by bleeding (30.3%). Eighty one percent believe surgical mentorship and supervision during initial cases would facilitate endoscopic DCR learning. Conclusions External Dacryocystorhinostomy is the preferred technique for treating primary acquired nasolacrimal duct obstruction. Learning endoscopic DCR early during fellowship training and high surgical volume to improve the learning curve dramatically impacts the adoption of the procedure.

This study presents a novel technique to measure the motion of the eyelid during blinking. High-speed imaging and digital image correlation (DIC) were employed to monitor the eyelid during blinking in a non-invasive manner. Both spontaneous and reflex blinks were studied. A black liquid eyeliner was used to generate a speckle pattern on the surface of the eyelid. Facet motion captured through a DIC analysis software generated kinematic data for each blink. Calculations using this data set yielded information on the duration of the blink, eyelid displacements, and peak eyelid velocities. A consistent data set quantified the difference between blink types and reinforced the accuracy and repeatability of this DIC analysis method to measure the kinematics of blinking.
