Abstract/OtherAbstract:
Purpose:  To examine size and frequency of parapapillary atrophy (beta zone) in patients with intrasellar or perisellar tumours and a glaucoma-like appearance of the intrapapillary optic disc region. Methods:  Thirty-four Chinese subjects with intrasellar or perisellar tumours and a glaucoma-like appearance of the intrapapillary optic disc region and 129 age-matched subjects randomly selected from the population-based Beijing Eye Study were enrolled. Beta zone was measured on fundus photographs. Size and location of the tumours were assessed on neuroradiological images. Results:  Beta zone was significantly more common (79 ± 7% versus 46 ± 4%; p = 0.001), and it was significantly larger in the tumour group than in the control group (circumferential extent: 135 ± 99 versus 57 ± 72; p < 0.001; relative area: 1856 ± 1923 versus 759 ± 1390; p = 0.002). The width of the intracerebral tumours was significantly associated with the circumferential extent of beta zone (r = 0.36, p = 0.039) and with the area of beta zone (r = 0.37, p = 0.032). Tumour width, height and depth were significantly (p = 0.001; p = 0.012; and p < 0.001, respectively) larger in the group of patients with beta zone than in the subgroup of patients without beta zone of parapapillary atrophy. Conclusions:  Patients with large intrasellar or perisellar tumours and a glaucoma-like appearance of the intrapapillary region as compared with a population-based control group had a significantly larger and more frequently occurring beta zone of parapapillary atrophy. It suggests that large parasellar or suprasellar tumours can be associated with typical glaucomatous abnormalities in the parapapillary and intrapapillary region of the optic nerve head. It may give hints for the pathogenesis of glaucomatous optic neuropathy.
