Portable Endoscopic Camera System Using Modified Action Camera for Endoscopic Sinunasal Examination

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 Duct Obstruction
  • Nasolacrimal Tract Obstruction

Interventions

DEVICE

Modified Portable Endoscopic Camera

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.
