GLP-I-(7-37) has potent insulinotropic effects in nondiabetic and diabetic subjects. Whether GLP-I-(7-37) is useful as a therapeutic medication in type II diabetes requires further investigation.

Motivated well-trained diabetologists can screen for diabetic retinopathy. The absence of detectable lesions by direct ophthalmoscopy indicates that automatic referral to an ophthalmologist is not necessary. However, if any level of retinopathy is detected or corrected acuity is worse than 20/30, referral to an ophthalmologist is required. In this setting, fundus photography is advised because it is the most sensitive means of detecting clinically significant retinopathy. If other nonophthalmologists can be trained to achieve similar results, current recommendations for ophthalmologic referral that require annual ophthalmologic examinations for most diabetic patients may need to be reconsidered.
