Bilateral Optic Disc Swelling with Persistent Visual Loss in Anemia: Case Report.

A 56-year-old man with a medical history of alcoholic cirrhosis presented with acute bilateral loss of vision. On admission, the patient had pale skin and low arterial pressure. Ophthalmic examination demonstrated a visual acuity of 6/9 in the right eye and the absence of light perception in the left.

Cortical Visual Connections via the Corpus Callosum are Asymmetrical in Human Infantile Esotropia.

Purpose: Besides chiasmal hemidecussation, interhemispheric connections are likely important in human binocularity. The corpus callosum (CC) is the major fiber bundle in the mammalian brain which mostly connects homologous cortical areas in the two hemispheres. Visual interhemispheric connections were found abnormal in strabismic cats.

Retinal nerve fiber layer thickening in ARSACS carriers.

Purpose: Two Caucasian Belgian families were diagnosed with autosomal recessive spastic ataxia of Charlevoix-Saguenay (ARSACS). The ophthalmological findings in both ARSACS disease and carriers are described.

Methods: In addition to a complete ophthalmological assessment, in both patients and carriers, spectral-domain Optical Coherence Tomography scans of the peri-papillary retinal nerve fiber layer were performed.

Breast Cancer Metastasis Presenting as Conjunctival Chemosis.

A 72-year-old woman presented with a painful right eye. A few weeks before, she had noticed a red, swollen area in the conjunctiva of the same eye. On slit lamp examination, it appeared as chemosis and vascular injection; artificial tears were prescribed.

Does dominance of crossing retinal ganglion cells make the eyes cross? The temporal retina in the origin of infantile esotropia – a neuroanatomical and evolutionary analysis.

A closer look at the evolution of the eye and the brain provides a possible explanation for both the origin of infantile esotropia and its motor characteristics. In the course of evolution, the eyes have moved from a lateral to a frontal position. Consequently, the monocular visual fields started to overlap resulting in a binocular visual field.

A hypothetical mechanism for DVD: unbalanced cortical input to subcortical pathways.

Dissociated vertical divergence (DVD) is commonly encountered in the infantile strabismus syndrome. The movement is said to be dissociated since alignment differs between right and left eye fixation. It has been hypothesized that DVD is caused by a primitive reflex present in fish.
