Subretinal hemorrhage is the buildup of blood between the neurosensory retina and the retinal pigment epithelium (RPE), a delicate area where light is processed before being sent to the brain. It is a serious condition that can affect visual quality and, if extensive, may lead to lasting vision loss. Recognizing and understanding this condition is essential for preserving sight and ensuring timely care by our retina specialists.
This section explains what subretinal hemorrhage is, its origins, and how it affects vision.
Subretinal hemorrhage occurs when blood collects underneath the neurosensory retina but above the RPE. This blood leakage usually originates from either the choroidal or retinal circulation. Due to the sensitive nature of the retinal layers, even a small accumulation of blood can create a barrier that disrupts the necessary exchange of nutrients and oxygen, ultimately damaging the light-sensitive cells responsible for vision.
The origins of subretinal hemorrhage can be numerous, but a few common conditions stand out. One of the leading causes is choroidal neovascularization (CNV), often seen in patients with age-related macular degeneration (AMD). In CNV, new blood vessels form beneath the retina; these fragile vessels can leak or bleed, leading to a subretinal blood collection.
Other contributing factors include:
It is important to note that while some cases may be associated with well-known systemic conditions like diabetic retinopathy, the mechanisms causing subretinal hemorrhage often differ from those seen in other ocular bleeding disorders. Here’s the thing: because subretinal hemorrhage strikes at the outer layers of the retina, the damage can be more severe if not addressed on time.
When blood collects in the subretinal space, it creates a physical barrier between the photoreceptors—the cells that detect light—and the supportive RPE. This separation can lead to a disruption in the exchange of nutrients and removal of waste, resulting in rapid and sometimes irreversible damage to photoreceptors.
In experimental animal studies, irrecoverable photoreceptor damage has been observed within just one to three days after hemorrhage due to two main factors:
This disruption not only affects the clarity of vision but, if the hemorrhage is extensive, may lead to permanent visual impairment.
This section details the risk factors that predispose individuals to subretinal hemorrhage and outlines the diagnostic approaches used by our retina specialists.
Several underlying conditions can predispose a person to developing a subretinal hemorrhage. Among these, neovascular AMD is the most prevalent cause. In this condition, patients may develop different types of CNV:
Other conditions that may result in subretinal hemorrhage include:
Moreover, the use of anticoagulants may raise concerns among patients with neovascular AMD, but studies have shown that, with proper suppression of neovascular activity using anti-VEGF injections, the risk of subretinal hemorrhage is not significantly increased by these medications. Our retina specialists emphasize optimizing blood pressure and overall cardiovascular health as part of a well-rounded approach to reducing the risk of bleeding complications.
The location and extent of a subretinal hemorrhage greatly influence visual outcomes. When the hemorrhage involves the macula—the central area responsible for sharp vision—the risk of long-term vision loss increases significantly. A larger or thicker hemorrhage is more likely to result in permanent damage because it creates a more extensive barrier between the retina and its nourishing layers.
Even in cases where the hemorrhage is smaller, the resulting toxic effects of blood degradation products, such as iron, can jeopardize photoreceptor integrity. These principles highlight the importance of early detection and management to safeguard visual function.
Diagnosing subretinal hemorrhage involves a careful examination of the retina using advanced imaging tools. Our retina specialists utilize various techniques to assess the condition:
These diagnostic methods are crucial for determining the best treatment strategy while providing patients with a clear understanding of their condition.
This section reviews both non-surgical and surgical treatment options available for managing subretinal hemorrhage.
Treatment for subretinal hemorrhage must be tailored to the underlying cause, the extent of bleeding, and individual patient factors. The management strategy often falls into either an observational approach or a more interventional treatment, depending on the severity and progression of the hemorrhage.
Here’s the thing: if the hemorrhage is small and the patient’s vision is only mildly affected, our retina specialists may recommend careful observation to allow the body to reabsorb the blood naturally. However, if the hemorrhage is significant, early intervention is crucial to minimize photoreceptor damage and improve visual outcomes.
In cases where the hemorrhage is extensive or vision is at risk, surgical interventions may be necessary. Several approaches exist for managing subretinal hemorrhage surgically:
Each surgical option carries its own risks and benefits. While surgery can reduce the duration of blood contact with the retina, complications such as recurrence of CNV, disciform scarring, or proliferative vitreoretinopathy (PVR) can occur, affecting long-term visual improvement.
Not every subretinal hemorrhage requires surgical intervention. For some patients, especially when the hemorrhage is smaller and the underlying neovascular activity is well controlled, a non-surgical approach may be preferred. Non-surgical management typically involves:
A growing body of evidence suggests that anti-VEGF therapy alone, or in combination with pneumatic displacement, can preserve visual acuity effectively without the need for more invasive procedures. However, individual response can vary, emphasizing the need for personalized care.
This section discusses the visual prognosis, the role of advanced imaging, and the promise of emerging treatments in the management of subretinal hemorrhage.
The visual prognosis for patients with subretinal hemorrhage can be unpredictable. Multiple factors impact the final outcome, and understanding these can help in tailoring the treatment plan:
Understanding these factors can help guide treatment decisions. Our retina specialists carefully evaluate these elements during the diagnostic process, ensuring that each patient receives a tailored management plan that considers both the potential benefits of early intervention and the risks inherent in any surgical procedure.

Advanced imaging techniques like optical coherence tomography (OCT) and fluorescein angiography play a pivotal role in managing subretinal hemorrhage. These tools allow for:
This level of detailed assessment ensures that our retina specialists can optimize treatment strategies and adjust them as necessary to maximize the likelihood of a favorable visual outcome.
Research into the treatment of subretinal hemorrhage is ongoing, and several experimental approaches show promise. Some animal models have demonstrated that early administration of tissue plasminogen activator (tPA) can decrease the toxic effects of the clot on photoreceptors by facilitating faster clot lysis. Although the benefits appear promising, clinical studies in humans are still required to establish safety and efficacy parameters.
Other emerging techniques include refined surgical approaches that combine vitrectomy with adjunctive treatments like pneumatic displacement to minimize surgical trauma and improve outcomes. While these approaches have shown variable results in early studies, they represent a critical area of innovation in retinal care.
There is often a delicate balance between intervening early to remove the hemorrhage and giving the eye time to recover naturally. Key considerations include:
Our approach emphasizes personalized care that considers all these factors while prioritizing the preservation of vision. Each decision is made after thorough examination and discussion with the patient regarding potential outcomes.
This section offers guidance on preventive strategies and emphasizes when immediate clinical attention is needed.
Beyond immediate treatment, preventive measures play a crucial role in reducing the risk of subretinal hemorrhage, particularly in patients with underlying conditions such as neovascular AMD. A few important strategies include:
Embracing these lifestyle and treatment measures can significantly lower the risk of future subretinal hemorrhagic events and promote overall retinal health.
Research continues to refine our understanding of subretinal hemorrhage treatment outcomes. For instance, the Submacular Surgery Trials Group B provided valuable insights by comparing surgical intervention with observational management in patients with CNV-related hemorrhages. The study indicated that, in many cases, there was no statistically significant advantage of submacular surgery over careful observation regarding improvements in best-corrected visual acuity (BCVA).
Such findings underline the complexity of treating subretinal hemorrhage and suggest that, for some patients, less invasive strategies coupled with rigorous follow-up may offer outcomes comparable to surgery while minimizing additional risks.
Additionally, retrospective studies have shown that the adjunctive use of tPA with surgical techniques might help reduce the extent of photoreceptor damage by promoting quicker clearance of the hemorrhage. However, these approaches require careful balancing, as the potential for tPA toxicity necessitates adherence to safe dosage guidelines.
