Laminar thickness measurement outstrips RNFL measurement in diagnosing glaucoma

Laminar thickness measurement was more reliable than peripapillary retinal nerve fiber layer thickness measurement in diagnosing normal tension glaucoma, according to a study.The study included 68 patients with primary open-angle glaucoma and 76 patients with normal-tension glaucoma. A control group comprised 65 healthy patients. The Spectralis optical coherence tomography system (Heidelberg Engineering) was used to image the peripapillary retinal nerve fiber layer (RNFL) and optic nerve head.
