Summary

This study analyzed diabetic patients without evidence of glaucoma who underwent panretinal photocoagulation to determine the effect on optic disc topographic parameters in non-glaucomatous patients with proliferative diabetic retinopathy (PDR).

PROCEDURE

Panretinal photocoagulation

In cases of proliferative diabetic retinopathy (PDR), panretinal photocoagulation (PRP) is the first-line treatment. Although PRP reduces the risk of severe vision loss, it has been shown that laser energy can cause destruction to all layers of retina including the ganglion cells and the retinal nerve fiber layer (RNFL), and therefore generate visual field defects similar to that observed in glaucomatous damage. In such cases, visual field testing can be less helpful to evaluate glaucomatous damage in PDR patients treated with PRP.
