Idiopathic Optic Nerve Glioma: A Case Report.

Optic nerve gliomas are tumors that develop along the optic nerve pathway, most often classified as pilocytic astrocytomas. These growths are typically benign, especially in young children between the ages of one and six years, while the rarer malignant types are generally more aggressive and tend to appear in adults. Characteristically slow-growing, optic nerve gliomas are commonly located in the pre-chiasmal part of the optic nerve but can extend to post-chiasmal regions and into the brain if left untreated.

Background: The pathophysiologic mechanisms underlying early-onset myopia remain unclear; in this study, we investigate the pathogenesis by examining the interrelationships between axial length to corneal curvature radius ratio ( ) and choroidal blood flow.
Methods: This cross-sectional study included 202 eyes from myopic children, categorized into 141 eyes with mild myopia, 47 eyes with moderate myopia, and 14 eyes with high myopia. Optical coherence tomography angiography (OCTA) was used to measure choroidal blood flow perfusion within a 6 mm × 6 mm area of the macular region, divided into nine subareas based on ETDRS partitioning: macular fovea, nasal side 1, superior 1, temporal side 1, inferior 1, nasal side 2, superior 2, temporal side 2, and inferior 2.
Simultaneous central retinal vein and cilioretinal artery occlusion in a young female patient with progestin-only oral contraceptive use: a case report.
J Med Case Rep
January 2025
Faculty of Medicine, Nangarhar University, Nangarhar, Afghanistan.
Background: Central retinal vein occlusion and cilioretinal artery occlusion are rare but serious ocular conditions that can lead to significant visual impairment. While few cases of central retinal vein occlusion and cilioretinal artery occlusion have been individually reported, concurrent occlusion of both vessels is extremely rare, particularly in younger patients without traditional vascular risk factors. We present the first reported case of simultaneous central retinal vein occlusion and cilioretinal artery occlusion in a young female patient associated with short-term use of progestin-only oral contraceptives (OCPs).

BMC Ophthalmol

Department of Ophthalmology, The First Affiliated Hospital of Bengbu Medical University, Bengbu, Anhui, 233004, China.
Objectives: To evaluate the effects of short-acting cycloplegic agents, tropicamide and compound tropicamide, on ocular biological parameters and choroid thickness.
Methods: In this study, seventy pediatric subjects aged 6 to 13 years were randomly assigned to two groups: the tropicamide group and compound tropicamide group. Ocular biological parameters and choroidal thickness (CT) and subfoveal choroid thickness (SFCT) were measured in both groups and were retested 40 min after drug administration.
