We present the first reported case of histologically proven colorectal adenocarcinoma with metastatic spread to the optic nerve. A 49-year-old man, with a known history of rectal adenocarcinoma, presented with progressive loss of vision in his left eye. On presentation, he had no perception to light in his left eye and Snellen acuity of 6/36 in the right eye. Fundus examination showed a left globally swollen optic nerve with a few flame-shaped haemorrhages. A gadolinium-enhanced MRI scan demonstrated abnormal thickening of the anterior and mid-section of the optic nerve with high signal on STIR and postgadolinium enhancement. Optic nerve biopsy confirmed the presence of epithelial adenocarcinoma compatible with metastasis of gut origin. The patient died within 4 months of presentation.

Precis: In this prospective multicenter study, eyes with primary congenital glaucoma exhibited lower retinal vascular parameters compared to healthy controls, as assessed by optical coherence tomography angiography fractal dimension analysis.
Purpose: To study the retino-choroidal peripapillary microvascular pattern in primary congenital glaucoma (PCG) using fractal dimension (FD) analysis and compare it to healthy controls.
Methods: This was a prospective multicenter comparative study.

Objectives: The study aimed to evaluate the effect of GeLMA/bFGF hydrogel loaded with dental pulp stem cells (DPSCs) on the repair and regeneration of traumatic optic nerve injury.
Materials And Methods: GeLMA/bFGF hydrogel was photo-cross-linked by LED light. The physical-chemical properties and cytocompatibility of GeLMA/bFGF hydrogel after being squeezed (GeLMA/bFGF-SQ) were evaluated by SEM and degradation analyses, as well as live/dead and CCK-8 assays, respectively.

Purpose: To survey the real-world effectiveness and cost of optic nerve sheath meningioma (ONSM) treating with Gamma Knife Radiosurgery (GKRS), and compare with the external beam radiation therapy (EBRT).
Methods: Retrospective, comparative study that included patients with primary ONSM treated with either GKRS or EBRT in Samsung Medical Center, Korea. The treatment response, and treatment costs were compared between GKRS and EBRT groups.

Background: Neurofibromatosis is a neurocutaneous syndrome that predisposes individuals to a variety of tumors. In type 2, these typically do not present until early adulthood. We present a case of an unusual fundus lesion in neurofibromatosis type 2 (NF2) in a young child.

Background: ROSAH syndrome is an autosomal dominant systemic disease featuring etinal dystrophy, ptic nerve edema, plenomegaly, nhidrosis and migrainous eadache. Ocular manifestation of ROSAH syndrome can simulate posterior uveitis, vasculitis, generalized retinal dystrophy and neuroretinitis.
Purpose: To report a case of a 17-year-old female presenting with recurrent vitreous hemorrhage on a background of dental anomalies and anhidrosis.
