GLAUCOMA AND SLEEP APNEA STUDY


Glaucoma is an eye disease where a build-up of pressure within the eye can damage the optic nerve, progressively getting worse and in some cases causing blindness. Our hope is to explore the relationship between glaucoma and the sleep condition known as sleep apnea. Those interested in being considered for this study must already have been diagnosed with glaucoma and will be interviewed with one of our specialist and be asked to undergo a screening sleep study.

Please contact Nancy at 416-603-5723 to inquire about the screening process and how you can join.

THAT

The Toronto Hospital Alertness Test (THAT) - is a 10-item self-report questionnaire designed to measure perceived alertness in the preceding week. The exact version of the scale was published in the original paper by C.M. Shapiro; C. Auch; M. Reimer; L. Kayumov; R. Heslegrave; N. Huterer; H. Driver; G.M. Devins. "A new approach to the construct of alertness." Journal of Psychosomatic Research (June 2006), 60 (6), pg. 595-603

STOP BANG

Our team has participated in the development of the STOP BANG, a screening questionnaire for OSA (Obstructive Sleep Apnea).  This questionnaire has been administered to about 2500 patients at the Toronto Western and Mount Sinai hospitals.  The STOP BANG consists of only 8 questions and was found to be very sensitive in detecting moderate and severe OSA, respectively.  The STOP BANG takes only a few minutes to complete and is easy to score.  Answering 'yes' to three or more items suggests that one is at greater risk of having OSA.
This version is in common usage. The STOP BANG has been translated into several languages including Bengali, Arabic, Tagalog (Filipino), Cantonese, Mandarin, Russian, Serbo-Croatian, and Ukrainian.

The exact version was published in the original paper by Frances Chung, F.R.C.P.C.,* Balaji Yegneswaran, M.B.B.S., Pu Liao, M.D., Sharon A. Chung, Ph.D., Santhira Vairavanathan, M.B.B.S., Sazzadul Islam, M.Sc., Ali Khajecdehi, M.D., Colin M. Shapiro, F.R.C.P.C. STOP Questionnaire.
