A 66-year-old female with a history of sinusitis presented with persistent diplopia and worsening eyelid swelling. Examination revealed bilateral vision loss, cranial nerve palsies, left-sided chemosis, proptosis, and edema. Initial imaging showed sphenoid sinus opacification, bilateral ethmoid disease, lack of filling of bilateral cavernous sinuses, and partial thrombosis of the left superior ophthalmic vein. The sinus findings were evaluated with endoscopic sinus surgery, which was unremarkable. Subsequent orbital imaging suggested the lesions were in keeping with tumor thrombus as opposed to bland thrombus. CT scans revealed a large mass in the right axilla, which was biopsied and confirmed the diagnosis of diffuse large B-cell lymphoma (DLBCL). The patient was treated with anticoagulation, steroids, and chemotherapy resulting in marked improvement. Our report highlights a rare case of tumor thrombus from DLBCL causing bilateral cavernous sinus thrombosis and, to the best of our knowledge, the first documented case of superior ophthalmic vein thrombosis from tumor thrombus.

Purpose: We describe an atypical presentation of an 11-year-old female with enhanced S-cone syndrome (ESCS).
Methods: Case report. The patient underwent a thorough ophthalmic examination and investigations such as colour fundus photography, optical coherence tomography, fundus autofluorescence, fluorescein and indocyanine angiography, an electroretinogram and genetic testing.

Objectives: This study compares the cosmetic and functional outcomes of corneal tattooing/keratopigmentation and ocular prostheses in rehabilitating disfigured eyes, focusing on esthetic appearance and emotional well-being.
Methods: Ninety-two patients were included: 48 received corneal tattooing, and 44 were fitted with ocular prostheses. Anophthalmic surgery was indicated for trauma, painful blind eye, endophthalmitis, tumor, and corneal ulcer, while corneal tattooing was performed for trauma, corneal ulcer, and endophthalmitis.

Purpose: We investigated changes in macular topography and their association with visual acuity and metamorphopsia in the idiopathic epiretinal membrane (iERM).
Methods: Twenty-four eyes that underwent vitrectomy and ERM removal with internal limiting membrane peeling were included in this study. Best-corrected visual acuity (BCVA) and horizontal/vertical metamorphopsia scores (h and vM-scores in the M-chart) were assessed.

Failure of central nervous system (CNS) axons to regenerate after injury results in permanent disability. Several molecular neuro-protective and neuro-regenerative strategies have been proposed as potential treatments but do not provide the directional cues needed to direct target-specific axon regeneration. Here, we demonstrate that applying an external guidance cue in the form of electric field stimulation to adult rats after optic nerve crush injury was effective at directing long-distance, target-specific retinal ganglion cell (RGC) axon regeneration to native targets in the diencephalon.

Background: Spectrum Domain-Optical Coherence Tomography (SD-OCT) is a non-invasive technology that acquires cross-sectional images of retinal structures allowing neural fundus integrity assessment. Macular thickness and retinal nerve fiber layer (RNFL) thickness measured by an SD-OCT have been used as a indicator of Alzheimer's disease (AD) and amnestic mild cognitive impairment (aMCI). However which portion of retinal RNFL is the most sensitive area among normal control, aMCI and AD is not clear yet.
