A retina specialist evaluates diseases affecting the retina, macula, and vitreous. Some symptoms require urgent assessment, while others should prompt a scheduled retinal examination.
Serving patients searching for a Dallas Retina Specialist, Fort Worth Retina Specialist, and North Texas Retina Specialist.
A retina specialist should evaluate new flashes or floaters, a curtain or shadow in the vision, sudden vision loss, new distortion, a central dark spot, or retinal changes related to diabetes or macular degeneration. A sudden curtain, rapidly increasing flashes or floaters, or abrupt loss of vision may represent a retinal tear, retinal detachment, bleeding, or another emergency and should be assessed promptly.
Seek prompt retinal evaluation for any of the following:
These symptoms do not always mean a retinal emergency, but delaying an examination can reduce treatment options when a retinal tear, detachment, bleeding, or wet macular degeneration is present.
Retina specialists diagnose and treat conditions involving the retina, macula, and vitreous, including:
People with diabetes may develop retinal damage before they notice symptoms. Regular dilated retinal examinations are important even when vision seems normal. A retina specialist may be recommended when diabetic retinopathy, retinal swelling, bleeding, or vision change is identified.
New blurred vision, floaters, dark areas, or distortion in a patient with diabetes should be evaluated rather than assumed to be a temporary glucose-related change.
New distortion, waviness, difficulty recognizing faces, or a central dark spot can result from wet macular degeneration, macular edema, macular hole, or another macular condition. Because some of these diseases can progress quickly, new central-vision symptoms should be assessed promptly.
Call a retina practice promptly for new flashes, floaters, a curtain or shadow, or sudden central distortion. If the retina office is closed, symptoms are severe, the eye has been injured, or vision loss is sudden and profound, seek emergency medical evaluation. Sudden vision loss can also have neurologic or vascular causes that require immediate care.
This page provides general guidance and is not a diagnosis. When in doubt, urgent evaluation is safer than waiting.
A retina visit usually includes a detailed symptom history, vision testing, pupil dilation, and examination of the retina. OCT imaging, retinal photography, ultrasound, fluorescein angiography, or other tests may be used depending on the concern. Because dilation can blur near vision and increase light sensitivity, patients may wish to bring sunglasses and arrange transportation when appropriate.

No. Many flashes and floaters result from normal vitreous separation, but only a dilated retinal examination can determine whether a tear or detachment is present.
Not when symptoms are sudden or worsening. A curtain, shadow, new flashes, rapidly increasing floaters, sudden vision loss, or new central distortion should be evaluated promptly.
Referral requirements depend on the insurance plan. Patients and referring offices can contact Retina of North Texas or schedule online, and the practice can help clarify next steps.
Regular dilated eye examinations are essential because diabetic retinal disease can be present before vision changes occur. A retina specialist is often involved when retinopathy, swelling, bleeding, or other retinal abnormalities are found.
