Purpose: To determine if patients with primary acquired nasolacrimal duct obstruction (PANDO) have an increased prevalence of gastroesophageal reflux disease (GERD) compared to the general population. Methods: Cross-sectional case-control study. The Mayo Clinic Reflux Disease Questionnaire (RDQ) is used to help physicians diagnose GERD. The retrospective group consisted of patients who previously had a dacryocystorhinostomy (DCR) over a 4-year period by one surgeon (JTH) at one institution. The prospective group included consecutive patients undergoing DCR over an 8-month period for PANDO. The control group consisted of patients at our institution who did not have complaints related to nasolacrimal duct obstruction (NLDO) or a known history of NLDO. The RDQ score or a previous diagnosis of GERD was recorded for each patient. The prevalence of patients with GERD in each of the groups was compared to that in the control group using the Fisher exact test. Results: Nine (7.7%) of 117 patients in the control group were found to have GERD. Twenty-four of 65 (36.9%) patients in the retrospective cohort were found to have GERD. Twelve of 18 (66.7%) patients in the prospective cohort were found to have GERD. When the prospective and retrospective groups were compared to the control group, the presence of GERD was higher in patients with NLDO (p < .0001). Conclusion: Based on the results of this study and compared to the general population, GERD has an increased prevalence in patients with PANDO. GERD may have a role in the development of PANDO.

A 51-year-old man presented to the ophthalmology service with binocular diplopia and facial numbness. The patient was returning from a trip to Mexico. He reported having been hit in the left periocular region by a fish while swimming. Local doctors repaired a laceration in the left lateral canthus shortly after the incident. Orbital imaging revealed 2 needle-like foreign bodies corresponding to retained pieces of a needlefish jaw in the left orbit. Given the location of the foreign bodies, observation with repeat imaging was deemed more appropriate than surgical exploration. Subsequent imaging studies showed no migration of the foreign body, and the patient did not suffer from any related complications more than 7 years after the initial injury. [ABSTRACT FROM AUTHOR]

Background: Mohs surgery of eyelid skin cancers requires detailed knowledge of anatomy for precise surgery and accurate evaluation of histology., Objective: To review the histology of the peritarsal eyelid using frozen sections as encountered intraoperatively by Mohs surgeons., Methods: The authors review the literature describing the anatomy and histology of the peritarsal eyelid from the lens of a Mohs surgeon. Histology from select Mohs cases is used to frame the discussion of the microanatomy of this region., Results: The peritarsal eyelids contain a unique mixture of skin, muscle, tarsus, glandular tissue, and conjunctiva. The histologic appearance of many of these structures differs from skin found outside of this anatomic region. Tumors of the eyelid and periocular region may mimic normal histologic structures found within the peritarsal eyelid., Conclusion: The peritarsal eyelids have unique anatomy and associated histologic structures. Knowledge of the detailed histoanatomy is required for confident execution of Mohs surgery in this anatomic region., (Copyright © 2024 by the American Society for Dermatologic Surgery, Inc.
