Subjects With Clinical Diagnosis of Allergic Rhinitis Were Randomly Divided Into 2 Groups, With Patients in One Group Given One Treatment Session of Red Light Rhinophototherapy, Followed by Medical Treatment. Those in the Second Group Were Treated With Medical Treatment Only.

The device consists of a control box and 4 sets of two light-emitting nasal probes. Prior to treatment, each patient put on a pair of black tinted glasses, and had the nasal probes gently placed into both nostrils. A turn-on switch on the control box activated the probe and the timer was set at 15 minutes during which time 36 J of light energy was delivered to each nostril.
