Accessory lacrimal gland secretion mimicking seidel positivity following complex cataract surgery: Case report.

ABSTRACT

Purpose: To describe the presentation of lacrimal gland secretions mimicking a positive Seidel test following combined complex cataract surgery and endocyclophotocoagulation (ECP). Observation The patient presented with a posterior subcapsular cataract (PSC) most likely secondary to chronic steroid use for a history of chemical burns from a firework injury in 2019. This injury resulted in symblepharon formation and limbal stem cell deficiency. He also developed glaucoma secondary to steroid response and angle structure damage. On postoperative day 1 (POD 1) after combined cataract surgery and ECP, the patient's paracentesis was Seidel positive and aqueous suppression was started. On postoperative week 1 (POW 1), the paracentesis was Seidel negative; however, it was noted at this visit that there were 3 pinpoint areas in the superotemporal conjunctiva that were Seidel positive. Digital pressure did not worsen the leak. Ultrasound biomicroscopy (UBM) was performed at POW 2.5 and showed lacrimal gland ducts in the superotemporal conjunctiva. Given this, it is likely that the "Seidel positive" finding was not due to aqueous humor leakage, but secretions from lacrimal gland tissue that may have been dragged more anteriorly due to conjunctiva scarring, thus producing a false positive Seidel sign. Conclusion & importance This case highlights a false positive Seidel sign in the context of an eye with a complex ocular history and recent surgery. Clinicians should recognize that a false positive Seidel sign is possible if normal lacrimal gland anatomy has been disturbed.
