Purpose: It has been suggested that female sex steroids have neuroprotective properties that may reduce risk of glaucoma in premenopausal women. In this study, we explored the associations of optic disc measures with female reproductive factors in a population of young women.
Design: Cohort study.
Methods: Young women (n = 494; age range, 18-22 years) were recruited as part of the Western Australian Pregnancy Cohort (Raine) Study. Information on age at menarche, parity, and use of hormonal contraceptives were obtained from questionnaires. Participants underwent an eye examination, including spectral-domain optical coherence tomography imaging, to obtain optic disc parameters.
Results: Women who had given birth at least once (parous women; n = 10) had larger vertical neuroretinal rim widths (P < 0.001) than nulliparous women (n = 484) after correcting for use of hormonal contraceptives, intraocular pressure, refractive error, and family history of glaucoma. Furthermore, vertical and horizontal cup-to-disc ratios, which are inherently related to neuroretinal rim width, were found to be smaller among parous women compared with nulliparous women (both P < 0.001). Age at menarche and use of hormonal contraceptives were not significantly associated with any optic disc parameters.
Conclusions: We found limited evidence that female reproductive factors were related with optic disc parameters during young adulthood. The association between parity and optic disc parameter, though significant, should be further investigated given the small number of parous women in the current sample. Future follow-ups of this cohort will allow us to explore for any associations of these factors with optic disc parameters and glaucoma risk at an older age.

Purpose: Uveal melanoma (UM) is the most common primary ocular malignancy. The size and location of the tumor are decisive for brachytherapy with the β-emitting ruthenium-106 (Ru-106) plaque. The treatment of juxtapapillary and juxtafoveolar UM may be challenging because of the proximity or involvement of the macula and optic nerve and high recurrence rates.

: To evaluate the long-term effects of coronavirus disease (COVID-19) on optic disc and macular microvasculature. : 40 post-COVID-19 and 40 healthy subjects were included. Optical coherence tomography angiography (OCTA) was performed for all subjects at the first visit and repeated in the fourth and twelfth months.

Retinal ganglion cells (RGCs) typically respond to light stimulation over their spatially restricted receptive field. Using large-scale recordings in the mouse retina, we show that a subset of non- direction-selective (DS) RGCs exhibit asymmetric activity, selective to motion direction, in response to a stimulus crossing an area far beyond the classic receptive field. The extraclassical response arises via inputs from an asymmetric distal zone and is enhanced by desensitization mechanisms and an inherent DS component, creating a network of neurons responding to motion toward the optic disc.

Prcis: Community-based eye health screenings that incorporated fundus photography and optometric exams in a high-risk NYC population effectively identified a higher than average number of participants that required an in-office glaucoma evaluation.
Purpose: To report glaucoma screening rates and risk factors associated with referral for in-office glaucoma evaluation in the Manhattan Vision Screening and Follow-up Study (NYC-SIGHT).
Methods: In this 5-year, cluster-randomized clinical trial, eligible individuals aged 40 and older were recruited from affordable housing developments and senior centers.

Objective: Pigmentary posterior vitreous detachment (PVD), referred to as "black PVD," is a rare entity describing PVD along with pigment dispersion in the vitreous. There are a few case reports describing pigmentary PVD, yet the association between pigmentary PVD and uveal and optic disc tumors was not described before. The aim of this study was to report the clinical features of patients with pigmentary PVD associated with these tumors.
