Retina / Uvea / Vitreous
The pathophysiology of central serous chorioretinopathy (CSC) is complex and has not been fully elucidated. Suggested theories include hyperpermeability and increased hydrostatic pressure in the choroidal vasculature, which creates RPE detachments overwhelming the RPE barrier function, leading to accumulation of...
Understanding spaceflight-associated neuro-ocular syndrome (SANS): what do we know?
Introduction Formerly known as visual impairment and intracranial pressure syndrome (VIIP), space-related neuro-ocular syndrome (SANS) is defined by a collection of ophthalmic and neurological findings in astronauts after long-term spaceflight [1]. Changes in the eyeball, such as hyperopic shift, during...Traumatic ‘toy’ gun injury leading to permanent vision loss
