Evaluation and treatment for branch and central retinal vein occlusion, including macular swelling, bleeding, and abnormal retinal blood vessel growth.
Serving patients searching for a Dallas Retina Specialist, Fort Worth Retina Specialist, and North Texas Retina Specialist.
A retinal vein occlusion is a blockage in one of the veins draining blood from the retina. It can cause retinal bleeding, swelling in the macula, sudden blurred vision, and sometimes abnormal blood vessel growth that requires close monitoring.
A branch retinal vein occlusion affects one portion of the retina, while a central retinal vein occlusion affects the main retinal vein. The severity depends on how much retina is involved, whether the macula is swollen, and whether blood flow has been significantly reduced.
Symptoms often include sudden painless blur, a gray area, distortion, floaters, or decreased central vision. Any sudden vision change should be evaluated quickly because macular edema and retinal ischemia can develop early.
Evaluation typically includes a dilated exam, OCT imaging to identify macular edema, fundus photography, and fluorescein angiography or OCT angiography when blood flow, leakage, or abnormal vessels need assessment. Blood pressure, glaucoma risk, diabetes, and vascular risk factors may also be relevant.
Macular edema from vein occlusion is commonly treated with anti-VEGF injections. Many patients start with monthly treatment, then the interval is adjusted based on OCT fluid and vision. Laser treatment may be considered in selected cases, especially for abnormal peripheral vessels or persistent leakage patterns.
Some vein occlusions stabilize, while others require ongoing injections or surveillance for complications such as neovascularization, vitreous hemorrhage, or neovascular glaucoma. Retina of North Texas uses imaging-guided follow-up to determine treatment timing and reduce the risk of preventable vision loss.
Vein occlusions require more than a single diagnosis. The retina specialist must determine whether the central macula is swollen, whether retinal blood flow is reduced, whether abnormal blood vessels are forming, and whether the eye is at risk for pressure-related complications. Dr. Chavala uses retinal imaging and examination to guide both treatment and surveillance.
Patients often need a sequence of visits rather than one treatment. Retina of North Texas explains the plan in practical terms, including injection timing, OCT findings, and warning signs that should prompt earlier care. Coordination with the patient’s medical doctors may also be recommended when blood pressure, diabetes, or vascular risk factors are relevant.
Some patients improve quickly once swelling is controlled, while others need longer treatment or closer observation. Regular OCT comparison helps determine whether the vein occlusion is becoming less active, recurring between visits, or creating new complications that require a change in plan.
For patients who need injection treatment, Dr. Chavala has extensive high-volume experience, with >99% safety rate for eye injections in practice experience.
It is sometimes described that way because a retinal vein becomes blocked, but the eye findings and treatment are specific to the retina. Medical evaluation of vascular risk factors may be appropriate.
Vision can improve when swelling decreases, especially with timely treatment, but recovery depends on the amount of retinal damage and blood-flow loss.
Many patients begin with monthly injections, then extend treatment when OCT swelling and vision stabilize.
A new painless vision change should be evaluated promptly because macular edema or ischemia can require treatment and close monitoring.
