“…The optic disc abnormalities in TDS have been analyzed mainly by ophthalmoscopic examinations [1][2][3][4], whereas time-and spectral-domain OCT have only been used to assess peripapillary RNFL thickness [12][13][14][15][16][17] or macular changes at the border of the ectasia [18]. Only one recent study examined TDS by swept-source OCT [1], and provided us with an insight into the deeper structures within the optic nerve.…”

“…OCT has not been widely used in studying the ONH of the eyes with TDS. In TDS, OCT was mostly used to evaluate peripapillary RNFL thickness 42 or changes in the macula 43 but not in the ONH. One study examined the ONH in TDS eyes with swept-source OCT, but their description was qualitative and did not compare cases with RNFL damage and those without.…”

Purpose To study deep optic nerve head (ONH) morphology in tilted disc syndrome (TDS) and identify factors associated with retinal nerve fiber layer (RNFL) defect. Methods In patients with TDS, we evaluated the optic disc shape using the Bruch's membrane opening (BMO)–anterior scleral canal opening (ASCO) offset and measured the border tissue (BT) length, depth, and angle in the direction of the tilt, using radial ONH optical coherence tomography (OCT). We compared the parameters between the TDS groups with and without RNFL defects. Results Twenty-one eyes had no glaucomatous RNFL defect, and 38 eyes had a glaucomatous RNFL defect. The group with RNFL defects had a higher baseline IOP, larger tilt axis of BMO-ASCO optic disc margin (76.4° ± 14.5° vs. 87.9° ± 15.4°, P = 0.012), larger BMO–lamina cribrosa insertion (LCI) angle (25.6° ± 9.3° vs. 43.6° ± 15.2°, P < 0.001), and more lamina cribrosa (LC) defects (4.3% vs. 30.6%, P = 0.028) than without RNFL defects. The tilt axis and BMO-LCI angle were significant factors after adjusting for baseline IOP and LC defect. The BMO-LCI angle had excellent diagnostic power for glaucomatous RNFL defect in TDS, similar to the visual field mean deviation. Conclusions OCT-based large deep ONH BT angle and tilt axis were factors associated with the presence of RNFL defects in TDS. The results suggest a mechanism of RNFL defect associated with structural ONH deformation. Further investigations are warranted to understand the role of ONH structures in a general population with and without optic disc tilt.
