About The Condition
Understanding Retinal Vein Occlusion
Retinal vein occlusion (RVO) is a vascular condition that occurs when a vein in the retina becomes blocked, leading to impaired blood flow.
This can result in hemorrhage, fluid leakage, and swelling in the retina, often affecting central vision.
Early diagnosis and management are important to reduce the risk of vision loss and associated complications such as macular edema.
WHY EARLY REFERRAL MATTERS
Why Timely Referral for RVO is Critical
RVO is a time-sensitive condition that can lead to rapid changes in vision. Delays in assessment or treatment may increase the risk of visual impairment. Prompt referral allows for:
- Early confirmation of diagnosis
- Access to appropriate retinal imaging
- Timely initiation of treatment when indicated
Patients are assessed and managed by Dr. Varun Chaudhary in Hamilton.
SIGNS & SYMPTOMS
When to Refer A Patient for RVO
Consider referral for retinal assessment in patients with:
- Suspected or confirmed retinal vein occlusion (BRVO or CRVO)
- Sudden or subacute vision loss
- Macular edema on OCT or clinical exam
- Retinal hemorrhages or venous dilation/tortuosity
- Unexplained visual decline with vascular findings
- Uncertainty in diagnosis or management
Referral timing should reflect symptom severity and clinical findings. Patients may benefit from timely evaluation.
Delivered through Precision Retina Care
How We Manage RVO
RVO is managed through a structured clinical approach that includes detailed imaging, diagnosis confirmation, and individualized treatment planning. Care includes:
- Comprehensive retinal evaluation
- Multi-modal retinal imaging (IVFA, OCT and related technologies)
- Diagnosis confirmation and classification (branch or central RVO)
- Ongoing monitoring for complications such as macular edema
Treatment commonly involves intravitreal anti-VEGF therapy, with frequency and approach individualized based on disease severity and response over time.
Patients are assessed and managed by Dr. Varun Chaudhary in Hamilton. Care is delivered using a structured clinical approach (Precision Retina Care, PRC) to support timely access and coordination.
RAPID ACCESS MODEL

Frequently Asked Questions About RVO
What causes retinal vein occlusion?
RVO occurs when a retinal vein becomes blocked, often due to underlying vascular risk factors such as hypertension, diabetes, or other systemic conditions.
How quickly should a patient with suspected RVO be referred?
Patients with sudden or unexplained vision changes should be assessed promptly by an eye care professional. Referral timing is based on clinical presentation and level of concern.
What happens after a referral is sent?
Referrals are reviewed and triaged, and patients are contacted directly to assist with appointment coordination and appropriate next steps.
What treatments are available for RVO?
Treatment typically includes intravitreal injections (anti-VEGF therapy), with additional management depending on complications such as macular edema.
Will RVO patients require ongoing care?
Yes, many RVO patients require follow-up and ongoing treatment to monitor disease activity and guide treatment decisions over time.
Can patients participate in clinical trials?
Some patients may be eligible for clinical trials evaluating new therapies. Participation depends on study criteria and availability.
