Transient retinal artery occlusion.
Medical necessity for TRAO diagnosis and management includes evaluating the underlying cause, restoring blood flow to the retina, and preventing future vision loss. This may involve medication, procedures, and ongoing monitoring to minimize the risk of complications.
Assessment and management of retinal vascular occlusions, typically by ophthalmologists, including diagnosis, treatment, and follow-up care. This might involve evaluating the cause of the occlusion and prescribing medication or referring for procedures to restore blood flow and prevent further vision loss.
In simple words: Temporary blockage of an artery in the eye's retina (the back part that senses light). This causes short-term vision loss in the affected eye.
A temporary blockage of an artery in the retina, the light-sensitive layer at the back of the eye, causing a sudden, but temporary, decrease in vision. This blockage can be due to a blood clot or the buildup of fats and calcium deposits, narrowing the artery and temporarily disrupting blood flow to the retina.
Example 1: A patient presents with sudden, painless loss of vision in one eye, described as a "curtain coming down." The ophthalmologist diagnoses a transient retinal artery occlusion (TRAO) based on clinical findings and imaging studies. The vision improves within hours, confirming the transient nature of the occlusion., An elderly patient with a history of high blood pressure experiences temporary blurring of vision in one eye. An examination reveals a TRAO, likely caused by an embolus from atherosclerotic plaque. The patient is prescribed medication to manage blood pressure and cholesterol levels and advised to follow up for monitoring., During a routine eye exam, a patient is found to have a Hollenhorst plaque (cholesterol embolus) in a retinal artery. Though currently asymptomatic, the patient is at risk for TRAO and other retinal vascular events.The patient is counseled on risk factors and preventative measures.
Detailed documentation of the patient's symptoms, including onset, duration, and characteristics of vision loss. Results of ophthalmologic examination, including visual acuity, funduscopy, and any imaging studies (e.g., fluorescein angiography, optical coherence tomography). Relevant medical history, such as hypertension, diabetes, or other vascular diseases. Treatment plan and follow-up recommendations.
