Over the following 3 months, he had further progressive visual impairment due to right central retinal vein occlusion (CRVO) and then left CRVO. Soon thereafter, during a hospital admission for infected submandibular gland, he was noted to have secondary hypothyroidism and persistent hypokalaemia which led to the diagnosis of Cushing\u2019s syndrome. This case was unusual as the patient did not manifest any classical features of Cushing\u2019s syndrome at the time of presentation with bilateral CRVO, and only 3 months later had dramatic weight loss, muscle weakness and acute psychosis. He received intravenous etomidate and underwent emergency transsphenoidal hypophysectomy with dramatic clinical and biochemical improvement and complete visual recovery in the left eye but unfortunately vision in the right eye remained limited to hand movements.<\/jats:p>","DOI":"10.1136\/bcr-2020-238204","type":"journal-article","created":{"date-parts":[[2021,1,25]],"date-time":"2021-01-25T11:41:18Z","timestamp":1611574878000},"page":"e238204","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Retinal
