Background: Shock can lead to ischemic injury of organs. Ischemic injury of the optic nerve may even cause blindness.
Case Description: A 61-year-old female patient was admitted to ICU with septic shock. When recovering, she was only able to determine the difference between light and dark; before admission her vision was good. Ophthalmologic examination revealed slow pupillary reflexes and pale, atrophic optic discs. The diagnosis of bilateral shock-induced ischemic optic neuropathy was made. The patient was permanently blind and traumatised by her experiences during her hospital stay when her blindness was not yet recognised.
Conclusion: Blindness caused by ischemic optic neuropathy is a rare and severe complication of shock that is usually irreversible. Early recognition is important in order to allow appropriate communication with, and approach of the patient to prevent traumatic experiences and promote rehabilitation.

Objective: To investigate the short-term blood flow changes and image features of the retina and choroid in patients who underwent carotid artery revascularization (CAR) for severe carotid artery stenosis using widefield swept-source OCT angiography (OCTA).
Design: Prospective study.
Participants: This prospective study included 112 eyes (56 eyes on the ipsilateral side and 56 eyes on the contralateral side) of 56 participants with severe carotid artery stenosis.

Background And Aims: Histologic studies indicated that healed plaque, characterized by a multilayered pattern, is indicative of prior atherothrombosis and subsequent healing. However, longitudinal in vivo data on healed plaque formation in non-culprit plaques are limited. This study aimed to investigate serial changes and clinical significance of new layered pattern formation in non-culprit plaques in patients with acute coronary syndromes (ACS) using serial optical coherence tomography (OCT) imaging.

Clinical Relevance: There are many recognised risk factors for retinal vein occlusions. It is plausible that musicians who play wind instruments or use their voice as their primary instrument may be at increased risk of branch retinal vein occlusions through repeated Valsalva manoeuvre.
Background: Repeated valsalva manoeuvres are commonly performed by musicians using high resistance wind instruments.

Traumatic optic neuropathy (TON) is a rare condition resulting from damage to the optic nerve due to craniofacial trauma. It can present as direct or indirect injuries, with mechanisms ranging from mechanical disruption by fractures in direct TON to transmitted forces causing shearing and ischemia in indirect TON. These injuries often lead to significant visual impairment or complete vision loss, requiring timely diagnosis and intervention.
