- The effect of optic disc diameter on vertical cup to disc ratio percentiles in a population based cohort: the Blue Mountains Eye Study. Crowston, J. G.; Hopley, C. R.; Healey, P. R.; Lee, A.; Mitchell, P. // British Journal of Ophthalmology;Jun2004, Vol. 88 Issue 6, p766
Objective: The 97.5th percentile for vertical cup to disc ratio (VCDR) has been proposed as a useful tool to assist in the diagnosis of glaucoma in population studies. Previous reports of VCDR percentiles have either not been adjusted for disc size or have been calculated by regression analysis...

- Peripapillary Retinal Nerve Fiber Layer Thickness and Peripheral Microcirculation in Raynaud's Disease. Pedrosa, Catarina; Pina, Susana; Seguro Paula, Filipe; Amaral, Marta; Trancoso Vaz, Fernando // Vision Pan-America: The Pan-American Journal of Ophthalmology;2016, Vol. 15 Issue 3, p80
Purpose: Normal-tension glaucoma has been associated with systemic vascular diseases such as peripheral vasospasm. This study aims to evaluate the influence of peripheral vasospasm on the thickness of the retinal nerve fiber layer (RNFL) in Raynaud's disease (RD), and the correlation between...
- FeokromasitomalÄ± Bir Olguda Optik Sinir BaÅŸÄ±nÄ±n Kapiller Hemanjiomu. AY, Berrin Gül; KIRGIZ, Ahmet; ORUÇ, Yavuz; ARSLAN, Sermal; YILMAZ, Turgut // Retina-Vitreus/Journal of Retina-Vitreous;Jun2011, Vol. 19 Issue 2, p134
The retinal capillary hemangioma is a rare, benign vascular tumor that arises from the blood vessels of the retina or optic disc. We present the case of a 17-year-old male with pheochromocytoma and capillary hemangioma of the optic nerve head in the left eye.
