From the Guidelines
Hypertension management in patients with intraocular hemorrhage requires careful consideration of blood pressure reduction to prevent further bleeding while maintaining adequate perfusion, with the most recent guidelines suggesting careful acute blood pressure lowering with i.v. therapy to <180 mmHg in patients with systolic BP ≥220 mmHg 1. In the context of intraocular hemorrhage, it is essential to balance the need to control blood pressure with the risk of compromising optic nerve perfusion. The 2024 ESC guidelines for the management of elevated blood pressure and hypertension provide valuable insights into the acute and short-term management of blood pressure in patients with cerebrovascular events, including those with intraocular hemorrhage 1. Key considerations in managing hypertension in patients with intraocular hemorrhage include:
- Immediate blood pressure lowering is not recommended for patients with systolic BP <220 mmHg, as per the 2024 ESC guidelines 1.
- In patients with systolic BP ≥220 mmHg, careful acute blood pressure lowering with i.v. therapy to <180 mmHg should be considered, taking into account the potential risks and benefits of such intervention 1.
- The choice of antihypertensive treatment should be determined by the type of organ damage and the specific clinical presentation, with intravenous therapy usually required in cases of hypertensive emergencies 1.
- Long-term management of hypertension in patients with intraocular hemorrhage may involve oral medications such as ACE inhibitors, ARBs, calcium channel blockers, or beta-blockers, with the goal of preventing further complications from uncontrolled hypertension 1.

From the Research
Hypertension and Intraocular Hemorrhage Treatment
- Hypertension can cause organ complications, including hypertensive retinopathy, which damages the retinal microcirculation and the retinal nerve fiber layer (RNFL) 2.
- High blood pressure can also lead to an exacerbation of diabetic retinopathy, an increase in intraocular pressure (IOP), and trigger the formation of thromboembolic lesions 2.
- Intraocular pressure-lowering effects of commonly used fixed-combination drugs with timolol have been evaluated in a systematic review and meta-analysis, showing that all six commonly used fixed-combination drugs containing timolol can effectively lower IOP in patients with primary open-angle glaucoma (POAG) and ocular hypertension (OHT) 3.
- A comparison of the diurnal effects of timolol 0.5% and metoprolol 3.0% eye drops on the intraocular pressure, blood pressure, and heart rate in glaucoma patients showed that both agents produced a significant ocular hypotensive effect for more than 12 h 4.
- The effect of 3% metoprolol and 0.5% timolol eye drops on the intraocular pressure (IOP) was compared in healthy subjects, showing that both drugs caused significant reductions in IOP with a maximal effect 2 to 8 h after administration of the drug 5.
Treatment Options
- Fixed-combination drugs containing timolol, such as latanoprost/timolol and travoprost/timolol, have been shown to be effective in lowering IOP in patients with POAG and OHT 3.
- Timolol 0.5% and metoprolol 3.0% eye drops have been compared in a diurnal study, showing that both agents produced a significant ocular hypotensive effect for more than 12 h 4.
- The use of adaptive optics (AO) combined with optical coherence tomography (OCT) has been proposed to evaluate the retinal microvasculature in patients with hypertensive retinopathy 2.
Complications and Management
- Ocular trauma can lead to traumatic glaucoma, and treatment may be challenging depending on the mechanism of damage 6.
- Hypertensive retinopathy can result in progressive and painless vision deterioration in some groups of patients, and the harmful effect of increased BP on the eye is not only limited to hypertensive retinopathy but can also lead to an exacerbation of diabetic retinopathy and an increase in intraocular pressure (IOP) 2.
