Treatment Overview
Submacular Hemorrhage Removal Surgery is an advanced retinal procedure performed to clear blood trapped beneath the macula — the central area responsible for sharp vision. Submacular hemorrhages are typically caused by wet Age-related Macular Degeneration (AMD), Polypoidal Choroidal Vasculopathy (PCV), trauma, or retinal vascular diseases. When untreated, the toxic effects of blood on the photoreceptors can lead to rapid and permanent vision loss.
In Korea, this surgery is performed using cutting-edge retina surgical systems, precision drug delivery, and minimally invasive techniques:
- Pars Plana Vitrectomy (PPV) to access the submacular space
- Subretinal tPA (Tissue Plasminogen Activator) injection to dissolve clots
- Pneumatic displacement with gas bubble (C3F8/SF6) to shift hemorrhage away from the macula
- 27–25G micro-incision vitrectomy for minimal trauma and fast recovery
- Wide-angle viewing systems for high-precision manipulation
- Intraoperative OCT for real-time guidance
- Optional anti-VEGF injection to control underlying neovascularization
- Postoperative positioning guidance for optimal blood displacement
Korean retina surgeons are globally recognized for their expertise in complex submacular procedures, making Korea a top destination for this sight-saving surgery.
Purpose & Benefits
Purpose
- Remove or displace submacular blood to prevent photoreceptor damage
- Restore or improve central vision
- Reduce toxicity caused by hemoglobin and iron accumulation
- Stabilize retinal structure
- Improve retinal response to anti-VEGF therapy
- Prevent permanent macular scarring
Benefits
- Rapid removal of toxic blood from under the macula
- High success rates with advanced Korean surgical techniques
- Minimally invasive micro-incision vitrectomy
- Significant improvement in visual prognosis if performed early
- Combined therapy approach improves long-term outcomes
- Effective even in large, dense, or longstanding hemorrhages
- Korea offers high-precision imaging and surgical systems (OCT, tPA-guided displacement)
Ideal Candidates
This surgery is ideal for:
- Patients with submacular hemorrhage due to wet AMD or PCV
- Individuals with traumatic submacular bleeding
- Patients whose hemorrhage has caused acute vision decline
- People with thick or extensive submacular blood not suitable for pneumatic displacement alone
- Anyone requiring early intervention to preserve macular function
- Patients who failed anti-VEGF-only or pneumatic treatment
Possible Risks & Complications
Minor / Transient Issues
- Mild redness or irritation
- Temporary vision fluctuations
- Small floaters
- Gas bubble-related visual obstruction (temporary)
Rare / Serious Risks
- Retinal detachment
- Recurrent bleeding
- Increased intraocular pressure
- Endophthalmitis (infection)
- Macular hole formation
- Need for additional surgery

Related Diagnostic & Treatment Techniques
- Optical Coherence Tomography (OCT) – Thickness and blood depth assessment
- OCT-A – Detect underlying CNV or PCV
- Fluorescein Angiography / ICGA – Determine bleeding source
- Subretinal tPA Injection – Dissolve clot for displacement
- Pneumatic Displacement – Gas bubble-assisted blood movement
- Anti-VEGF Therapy – Control CNV and prevent recurrence
- Vitrectomy – Main approach for surgical removal
- Micro-Pulse or Endolaser – For bleeding source stabilization
Treatment Process in Korea
Step 1 – Preoperative Assessment
- Comprehensive retinal exam
- OCT, OCT-A, and angiography to map hemorrhage
- Evaluation of CNV activity
- Surgical planning using AI-assisted measurements
- Discussion of gas bubble positioning requirements
Step 2 – Surgical Procedure
- Local or general anesthesia
- Pars plana vitrectomy (23–27G)
- Removal of vitreous to access subretinal space
- Subretinal tPA injection to liquefy blood
- Gas tamponade (SF6/C3F8) for blood displacement
- Optional: Anti-VEGF injection for CNV
- Intraoperative OCT to ensure proper displacement
- Micro-incision sutureless closure
Step 3 – Postoperative Follow-Up
- Face-down or instructed positioning for 2–5 days
- IOP check and OCT evaluation
- Anti-VEGF follow-up if AMD/PCV present
- Regular monitoring for recurrence or scarring
Duration: 30–60 minutes
Setting: Retina surgery center or specialized operating suite
Recovery & After-Care
After-Care Guidelines
- Maintain required face-down or tilted positioning
- Avoid air travel while gas bubble is present
- Use prescribed antibiotic and anti-inflammatory drops
- Avoid strenuous activity for at least 1–2 weeks
- Report any new flashes, pain, or severe vision changes immediately
Recovery Timeline
- 1–2 Days: Initial improvement as blood begins shifting
- 1–2 Weeks: Gas bubble slowly absorbed, vision begins stabilizing
- 1–3 Months: Major visual recovery
- 3–6 Months: Final outcomes after retina settles and edema resolves
Results & Longevity
Expected Results
- Significant clearing of submacular blood
- Improved or restored central vision
- Reduced risk of permanent macular scarring
