Nasal endoscopic examination is an important part of the preoperative assessment in patients presenting with naso-lacrimal duct obstruction, particularly when planning endoscopic dacryocystorhinostomy (DCR). Using a smartphone adaptor with the nasal endoscope enables live image display on the screen of the smartphone, which can be viewed by more than one clinician at a time.

There is no need to hold the eyepiece of the endoscope, as this is attached to the smartphone and is held by an assistant. The smartphone adaptor (RVA Smart-Clamp) costs less than £115.00 and fits most of the-modern smartphones. This adaptor can be used with a flexible or rigid endoscope with a 31.75 mm eyepiece.

We use a smartphone adaptor for preoperative and post-operative examination in patients undergoing DCR and find it very useful in training junior doctors/fellows in the oculoplastic clinic. Attaching the smartphone adaptor to the flexible endoscope frees a hand of the clinician to allow removal of silicone stents postoperatively. We find this particularly useful, as flexible endoscope is more comfortable for patients compared to a rigid endoscope and can be used without the need of topical nasal anaesthetic or decongestant.

The smartphone adaptor with the nasal endoscope is significantly cheaper and a less cumbersome alternative than a camera with monitor attachment required for displaying the image.
