Brief Summary

This study is designed to compare two methods for performing a nasal endoscopic examination used in the evaluation of excessive watering or tearing of the eyes. The purpose of the study is to determine whether a new, smaller, modified camera system can produce images of the inside of the nose that are as clear and useful as those produced by the standard endoscopic camera system currently used in clinics. The study seeks to answer the question of whether a compact, easy-to-store camera system can provide similar diagnostic image quality to the traditional, larger tower-based system. The clinical steps of the nasal examination remain the same; the only difference is the type of camera system used to capture the images.

Conditions

Nasolacrimal Tract Obstruction; Nasolacrimal Duct Obstruction

Outcome Measures

Primary Outcomes (1)

• Image Quality Score of Modified Portable Endoscopic Camera System

  Image quality of the modified portable endoscopic camera system will be evaluated using a 5-point Likert scale assessing resolution, clarity of anatomical structures, and overall clinical utility. Three attending physicians will independently grade anonymized images from each nasal anatomical site. Scores will be compared with those obtained from the standard endoscopic tower.

  Grading completed within 3 months of enrollment completion.

Secondary Outcomes (1)

• Image Quality Score of Standard Endoscopic Tower System

  Grading completed within 3 months of enrollment completion.

Modified Portable Endoscopic Camera

Device: Modified Portable Endoscopic Camera

Interventions

Modified Portable Endoscopic Camera DEVICE

The Sony Action Camera was modified to allow direct coupling with a standard rigid nasal endoscope: 1. The native 180° wide-angle lens was replaced with a narrow-field 31° lens, enabling full-frame capture of the endoscopic image without peripheral distortion. 2. The camera housing was adapted by attaching a ¾-inch water pipe end connector, serving as a secure and stable mount for the endoscope eyepiece. The modified system captures both video and still images.

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Adults receiving care in the ophthalmology or otolaryngology outpatient clinics at the University of Arkansas for Medical Sciences (UAMS) who present with sinonasal or lacrimal tearing symptoms and require nasal endoscopic evaluation as part of routine clinical care. Potential participants will be identified only during their scheduled clinic visits, and no individuals will be contacted in advance. Eligibility confirmation will be based solely on information already available in the medical record during standard outpatient workflow. Individuals who meet eligibility will be approached in person during the clinic visit and invited to participate.

You may qualify if:

• Adult patients (≥ 18 years old) undergoing a clinically indicated nasal endoscopic examination
• Patients may include, but are not limited to, those presenting with tearing suggestive of nasolacrimal drainage obstruction or sinonasal disease

You may not qualify if:

• Children (Under the age of 18)
• Patients with over secretory tearing without clinical indication for nasal endoscopy
