ABSTRACT
PURPOSE:
To characterize the features of peripapillary atrophy (PPA), as imaged by spectral-domain optical coherence tomography (SD-OCT).METHODS:
SD-OCT imaging of the optic disc was performed on healthy eyes, eyes suspected of having glaucoma, and eyes diagnosed with glaucoma. From the peripheral beta-zone, the retinal nerve fiber layer (RNFL), the junction of the inner and outer segments (IS/OS) of the photoreceptor layer, and the Bruch's membrane/retinal pigment epithelium complex layer (BRL) were visualized.RESULTS:
Nineteen consecutive eyes of 10 subjects were imaged. The RNFL was observed in the PPA beta-zone of all eyes, and no eye showed an IS/OS complex in the beta-zone. The BRL was absent in the beta-zone of two eyes. The BRL was incomplete or showed posterior bowing in the beta-zone of five eyes.CONCLUSIONS:
The common findings in the PPA beta-zone were that the RNFL was present, but the photoreceptor layer was absent. Presence of the BRL was variable in the beta-zone areas.
