Study of Retinal Nerve Fiber Layer Thickness Within Normal Hemivisual Field in Primary Open-Angle Glaucoma and Normal-Tension Glaucoma

Detection of macular and circumpapillary structural loss in normal hemifield areas of glaucomatous eyes with localized visual field defects using spectral-domain optical coherence tomography

“…Furthermore, several studies have shown the presence of glaucomatous cRNFL defects in the retinal segments corresponding to intact hemifields, using various imaging devices including TD-OCT or SD-OCT [15][16][17][18][19][20][21][22]. Our current study using RTVue-100 SD-OCT has confirmed these findings.…”

Symmetry Analysis for Detecting Early Glaucomatous Changes in Ocular Hypertension Using Optical Coherence Tomography

“…Because of these conflicts, the accuracy of symmetry analysis is still questionable. However, some studies 33,34 have reported that the pattern of RNFL change is different in patients with high-or normal-tension glaucoma. Kuroda et al 33 reported that the RNFL thickness was reduced symmetrically in the superior and inferior quadrants in high-tension glaucoma, whereas a more localized defect of the inferior RNFL occurs in normal-tension glaucoma.…”

Retinal nerve fibre layer measurements are reduced in patients with obstructive sleep apnoea syndrome

“…The RNFL thickness has been shown to be decreased in the corresponding quadrant even when the visual field was still normal in patients with glaucoma. 11,18,19 The RNFL was found to be thinner and correlated with visual field loss in the superior and inferior quadrants. 20,21 It has been suggested and experience would support that the nasal and temporal RNFL measurements when used for the ratios may be more helpful at early stages as the thickness of the superior and inferior quadrants is affected earlier in glaucoma.…”
