This paper details an accurate method for computation of bending losses in rectangular optical waveguides which we combine with perturbation theory to account for the fields in the (outer) corner regions of the guiding channel. In the case of the weakly guiding channels of interest in optical signal processing, the correction to the loss coefficient due to the corner fields is shown to be in excess of 50%
