Sono case series: a 65-year-old man with right eye vision loss
Abstract
Case presentation A 65yearold man presents with a shadow in the left visual field of his right eye. This has progressed over the past week, and he presents to the ED because the shadow has involved his central visual field. He has also been experiencing right eye flashes and floaters. He has not had any trauma to the eye, and has no eye pain, discharge, fever, chills or history of similar symptoms. His medical history includes diabetes, hypertension, hyperlipidemia, right eye pseudophakia, and right eye retinal microaneurysm. His surgical history includes lens replacement. His home medications include lisinopril, amlodipine, metformin and atorvastatin, and he has no allergies. His triage vital signs showed BP of 178/80 mm Hg, HR of 98 beats per minute, temperature of 37°C, respirations of 14 and oxygen saturation of 98%. On physical examination, the patient is a man appearing his stated aged without distress. Right eye visual acuity was 20/30, not correctable with pinhole, and left eye visual acuity was 20/20. Tonometry shows 15 mm Hg in both eyes. Both pupils are equal, round and reactive to light. The right eye has total inferior nasal visual field deficiency, while the left eye visual field is full. Slit lamp exam showed normal conjunctivae, cornea and anterior chambers.
How strong is the evidence?
Evidence Hub reads this as a case series, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
