Case reports of neuro-ophthalmological complications of CIPD

The authors present three cases of neuro-ophthalmological complications of chronic inflammatory demyelinating polyradiculoneuropathy (CIPD). CIPD can lead to prominent nerve hypertrophy which can mimic other forms of neuropathy radiologically. In addition, complications can occur which can cause diagnostic difficulties. All...

UK ophthalmologists discuss value of ultra-widefield multimodality retinal imaging

Utilising optomap ultra-widefield (UWF™) multimodality retinal imaging with integrated SS (or SD) OCT in clinical practice contributes to identifying unexpected pathologies in a patient without visual complaints, report 81% of clinicians at industry webinar.

Ophthalmic learning through the lens of cognitivism and constructivism
