Rationale: Branch retinal artery occlusion (BRAO) is a rare complication of retinal arterial macroaneurysm (RAM), a low-incidence ocular disease.
Patient Concerns: A 75-year-old woman presented with a chief complaint of blurred vision.
Diagnoses: The patient for 4 days received a diagnosis of RAM combined with BRAO.
Interventions: The patient was treated with two successive intravitreal conbercept injections.
Outcomes: The patient's best-corrected visual acuity improved, and the RAM diminished.
Lessons: Administration of conbercept injection might be an effective treatment for complex RAM with BRAO.

Vision loss affects more than 7 million Americans and impacts quality of life, independence, social functioning, and overall health. Common and dangerous conditions causing sudden vision loss include acute angle-closure glaucoma, retinal detachment, retinal artery occlusion, giant cell arteritis, and optic neuritis. Acute angle-closure glaucoma features ocular pain, headache, and nausea; treatment includes pilocarpine eye drops, oral or intravenous acetazolamide, and intravenous mannitol.

Background: There are significant discrepancies in the optic nerve sheath diameter (ONSD) reported in the literature. We aimed to determine the ultrasonographic imaging features of ONSD and ophthalmic vessels in a healthy population, using a standardized protocol, and to estimate the effect of demographics and positioning changes on imaging measurements.
Methods: We measured the mean values of the ONSD in supine and sitting position and the Doppler imaging parameters of the ophthalmic, central retinal and short posterior ciliary arteries.

High altitude (HA) exposure induces impairments in visual function. This study was designed to dynamically observe visual function after returning to lowland and elucidate the underlying mechanism by examining the structure and function of retina and visual pathway. Twenty-three subjects were recruited before (Test 1), and one week (Test 2) and three months (Test 3) after their return from HA (4300 m) where they resided for 30 days.

Purpose: To investigate the effect of Henle fiber layer hemorrhage (HFLh) on retinal sensitivity (RS) before and after displacement of the submacular hemorrhage (SMH) caused by retinal arterial macroaneurysm (RAM) rupture.
Methods: This retrospective study included 31 eyes undergoing vitrectomy for SMH. Eyes were grouped based on the presence or absence of HFLh (HFLh [+/-] group).

Retinal artery occlusion (RAO) is a critical ophthalmic emergency with a high risk of significant visual impairment. While traditional treatment aims to promptly restore blood flow to the retina, recent research has investigated the potential benefits of anticoagulation therapy for managing this condition. This paper reviews current literature and clinical trials investigating the efficacy and safety of anticoagulant and antiplatelet therapies, such as systemic heparinization and direct oral anticoagulants and aspirin, in treating RAO.
