Electrophysiological Assessment in Birdshot Chorioretinopathy: Flicker Electroretinograms Recorded With a Handheld Device.

Purpose: The flicker electroretinogram (ERG) is a sensitive indicator of retinal dysfunction in birdshot chorioretinopathy (BCR). We explored recordings from a handheld device in BCR, comparing these with conventional recordings in the same patients and with handheld ERGs from healthy individuals.

Methods: Non-mydriatic flicker ERGs, using the handheld RETeval system (LKC Technologies), were recorded with skin electrodes at two centers.

Coarsening of choriocapillaris on optical coherence tomography angiography as a sign of acute idiopathic blind spot enlargement.

Purpose: Acute idiopathic blind spot enlargement is a rare syndrome that is classified within a spectrum of primary inflammatory choriocapillaropathies with circumscribed outer retinal dysfunction.

Observations: We observed coarsening of the choriocapillaris on en-face optical coherence tomography angiography when compared to the fellow eye in a patient with suspected acute idiopathic blind spot enlargement.

Conclusions And Importance: Increased granularity of the choriocapillaris as imaged by optical coherence tomography angiography may assist in the diagnosis of acute idiopathic blind spot enlargement, particularly during a global pandemic when access to electrodiagnostics is limited.

Intracranial Arterial Compression of the Anterior Visual Pathway.

Compression of anterior visual pathway (AVP) structures by intracranial arteries is observed not infrequently on neuroimaging. Whether or not such compression results in damage to these structures, however, remains unclear. This information is important to define as AVP compression by intracranial arteries may be a causative factor in patients with otherwise unexplained visual dysfunction.

Floppy eyelid syndrome "plasty" procedure: Employment of a periosteal transposition flap for surgery of floppy eyelid syndrome.

Importance: Floppy eyelid syndrome "plasty" (FESplasty) is a surgical technique that addresses underlying superior tarsal plate and lateral canthal instability in floppy eyelid syndrome (FES) and aims to restore normal anatomical and physiological function to the upper eyelid.

Background: To describe the use of FESplasty in the surgical management of FES, and to report outcomes in an initial patient cohort.

Design: Retrospective study.

Lymphocytic Hypophysitis Presenting as Bilateral Abducens Nerve Palsy: A Case Report.

Lymphocytic hypophysitis (LYH) is a neuroendocrine disorder characterised by autoimmune inflammation of the pituitary gland with varying degrees of pituitary dysfunction, visual field defects and ocular motility disturbance. The authors report an interesting case of a 50-year-old woman presenting with intermittent bilateral abduction deficits. Neuroimaging and histopathological findings are presented.
