What is the next step in managing a patient with retinal hemorrhage in the right eye, presenting with hypertension (elevated blood pressure) of 180/100 mmHg, experiencing their first episode and not currently taking any medications (nbs, or no significant background), after an ophthalmology (Opthalamo) consultation?

From the Guidelines

The patient with retinal hemorrhage in the right eye and elevated blood pressure of 180/100 mmHg should be immediately admitted to the ICU for intravenous antihypertensive therapy to prevent further target organ damage, as this is a hypertensive emergency. This patient is presenting with hypertensive retinopathy, which is an ocular manifestation of end-organ damage from severe hypertension, as defined by the 2020 international society of hypertension global hypertension practice guidelines 1. The retinal hemorrhage indicates that the hypertension is causing acute end-organ damage, making this a hypertensive emergency requiring prompt evaluation and treatment. According to the 2017 acc/aha/aapa/abc/acpm/ags/apha/ash/aspc/nma/pcna guideline for the prevention, detection, evaluation, and management of high blood pressure in adults, hypertensive emergencies demand immediate reduction of BP (not necessarily to normal) to prevent or limit further target organ damage 1.

The key points to consider in managing this patient include:

• The patient's blood pressure is severely elevated, with a systolic blood pressure of 180 mmHg and a diastolic blood pressure of 100 mmHg, which meets the criteria for a hypertensive emergency.
• The presence of retinal hemorrhage indicates target organ damage, which requires immediate attention to prevent further damage.
• The patient should be admitted to the ICU for close monitoring and intravenous antihypertensive therapy, as oral therapy is discouraged for hypertensive emergencies.
• The goal of treatment is to reduce the blood pressure to prevent further target organ damage, not necessarily to achieve a normal blood pressure.

In terms of specific treatment, the choice of antihypertensive agent will depend on the patient's individual characteristics and the presence of any comorbid conditions. However, according to the guidelines, intravenous therapy is usually required for hypertensive emergencies, and the choice of agent should be based on the type of organ damage present 1.

After the acute management, a comprehensive workup for the cause of hypertension would be appropriate, including renal function tests and evaluation for secondary causes of hypertension. The ophthalmologist can determine the severity of retinal involvement, potential for vision loss, and help guide blood pressure management to prevent further ocular damage.

From the FDA Drug Label

1 INDICATIONS & USAGE

1. 1 Hypertension Amlodipine besylate tablets is indicated for the treatment of hypertension, to lower blood pressure. Lowering blood pressure reduces the risk of fatal and nonfatal cardiovascular events, primarily strokes and myocardial infarctions These benefits have been seen in controlled trials of antihypertensive drugs from a wide variety of pharmacologic classes including Amlodipine besylate tablets.

The next step in managing a patient with retinal hemorrhage in the right eye, presenting with hypertension of 180/100 mmHg, is to lower the blood pressure to reduce the risk of further cardiovascular events, including stroke.

• The patient should be started on an antihypertensive medication, such as amlodipine, as indicated in the drug label.
• The patient's blood pressure should be closely monitored and the medication adjusted as needed to achieve a safe blood pressure goal.
• It is also important to address the underlying cause of the retinal hemorrhage and to monitor the patient's vision for any changes or worsening of symptoms 2.

Next Steps in Managing a Patient with Retinal Hemorrhage

• The patient is presenting with hypertension (elevated blood pressure) of 180/100 mmHg and experiencing their first episode of retinal hemorrhage in the right eye, with no current medications.
• After an ophthalmology consultation, the next step would be to manage the patient's hypertension to prevent further complications, as suggested by studies 3, 4.
• The use of antihypertensive medications such as calcium-channel-blockers (e.g., amlodipine) or angiotensin-converting-enzyme-inhibitors (e.g., lisinopril) may be beneficial in reducing blood pressure and improving retinal microvascular changes 3.
• Combination therapy with an inhibitor of the renin-angiotensin system and a calcium channel blocker may also be effective in achieving blood pressure goals and providing additional cardiovascular protection 4.

Considerations for Antihypertensive Treatment

• The choice of antihypertensive medication should take into account the patient's individual characteristics and medical history, as some medications may have adverse effects on uric acid metabolism 5.
• Calcium channel blockers, ACE inhibitors, and angiotensin receptor blockers may be preferable options as they do not increase serum uric acid levels 5.
• The patient's response to treatment should be closely monitored, and adjustments made as necessary to achieve optimal blood pressure control and prevent further retinal damage.

Ophthalmology Consultation

• The ophthalmology consultation has likely assessed the patient's retinal hemorrhage and provided guidance on the need for further evaluation or treatment, as seen in studies on inpatient and emergency room ophthalmology consultations 6.
• The consultation may have also identified any underlying conditions that contributed to the retinal hemorrhage, such as diabetic retinopathy, and recommended appropriate management 7.
