NTU, SERI team in­vents pen cam­era for glau­coma de­tec­tion

BioSpectrum (Asia) - - SCIENCE NEWS -

A group of sci­en­tists at Nanyang Tech­no­log­i­cal Uni­ver­sity, Singapore (NTU Singapore), with clin­i­cians from the Singapore Eye Re­search In­sti­tute (SERI), have in­vented a new ‘pen cam­era’ that makes it eas­ier for doc­tors to di­ag­nose pa­tients with glau­coma.

The ‘pen cam­era’, called the Go­nioPEN, could help tackle the eye dis­ease with its abil­ity to de­tect the type of glau­coma in a faster and cheaper man­ner. It causes neg­li­gi­ble dis­com­fort, un­like the cur­rent go­nio­scopes, which are glass scopes that must be pressed against the eye­ball of the pa­tient for doc­tors to look at the eye’s drainage canal to di­ag­nose the cause. The Go­nioPEN com­bines a high-res­o­lu­tion cam­era and LEDs for il­lu­mi­na­tion to take a high qual­ity im­age of the hu­man eye. The pro­to­type pen cam­era, es­ti­mated to cost $5,000, is con­nected to a com­puter via a USB ca­ble. The cam­era cap­tures im­ages of the eye from four dif­fer­ent per­spec­tives and saves it to the com­puter, which can then be mag­ni­fied sev­eral times for a bet­ter di­ag­no­sis by an eye doc­tor.
