49 Possible Causes for Cup-to-Disc Ratio Increased

  • Ectropion

    Aside from increased optic nerve cupping (0.6 cup-disc ratio), the posterior segment examination results were normal.[]

  • Klinefelter Syndrome

    […] with a cup-disc ratio of 0.9 were assessed only in the right eye.[] While both eyes were treated with topical intraocular pressure-lowering medications, an increased intraocular pressure, visual field losses, and advanced optic disc damage[]

  • Exfoliation Syndrome

    Postoperatively, she was noted to have progressive increase in the cup-disc ratio but a normal intraocular pressure.[]

  • Glaucoma

    […] changes - localised or generalised thinning of the neuroretinal rim, enlargement of the optic cup and increased cup to disc ratio (1) nerve fiber layer defects (3) Although[] […] untreated (1) The disease is charcterised by: visual field loss - arcuate scotomas, nasal steps, altitudinal scotomas, focal defects e.g. paracentral scotomas (2) optic disc[] […] in most cases there is an increase in intraocular pressure (IOP) which is sufficient to cause damage to the optic nerve head and changes in the visual field, the disease[]

  • Pseudoexfoliation Syndrome

    On fundus examination these patients had cup disc ratio of 0.6.Visual field testing revealed arcuate scotoma.[] Conclusion: There is increased frequency of secondary glaucoma in patients with pseudoexfoliation.[]

  • Open Angle Glaucoma

    The association between these genetic variants and the phenotypic features, including the maximum intraocular pressure (IOP) and the vertical cup-to-disc ratio, was evaluated[] An almost 1.5 increase in the risk of POAG (P 0.0042, odds ratio 1.52) was found with a G allele of rs7081455 (PLXDC2).[]

  • Internal Carotid Artery Aneurysm

    […] bilateral asymmetrical cup/disc ratios, with normal intraocular pressures.[] Abstract A 41-year-old caucasian male was referred to the Glaucoma clinic at our tertiary referral centre with a diagnosis of normal tension glaucoma after the finding of increased[]

  • Open-Angle Glaucoma 1P

    […] in intraocular pressure (IOP), age, vertical cup/disc ratio, central corneal thickness and Humphrey visual field pattern standard. 4–6 Elevated IOP is a significant risk[] […] glaucoma (POAG), which accounts for approximately 90–95% of all glaucoma cases. 3 This slowly progressive disease is associated with several key risk factors, including an increase[]

  • Angle Closure Glaucoma

    This damage is seen in an increase in the “cup to disc ratio”. The large circle is the optic disc and the inner circle is the cup.[] Alterations in visual areas seem to parallel the cup to disc ratio, but not the duration of angle closure.[] CONCLUSIONS: Our results suggest that PACG may contribute to decreased functional centrality in the visual system and to increased degree centrality in cognition-emotional[]

  • Acute Angle Closure Glaucoma

    However, we assumed that the C/D ratio had increased above the normal range because the cup had enlarged.[] The C/D ratio is the ratio of the cup to the optic disc. The cup is a sink region at the head of the optic nerve in the center of the optic disc.[] Accurate measurement of disc size was difficult because of the edema.[]
