Recognizing Retinal Red Flags During Routine Eye Exams

During a routine eye exam, optometrists and general ophthalmologists are often the first to identify changes within the eye, sometimes even before patients experience vision changes. This can include early signs of retinal disease, such as diabetic retinopathy, age-related macular degeneration, retinal tears, or changes at the vitreomacular interface.
Since the presence of a retinal abnormality does not automatically indicate an urgent issue, primary eye providers are responsible for distinguishing findings that can be safely monitored from those that may pose a more immediate threat to vision and warrant a referral to a retina specialist. Recognizing these retinal red flags can help ensure patients receive targeted and timely care before vision loss occurs.
Common Retinal Signs and Symptoms That May Warrant Referral
Sudden Onset or Increase of Flashes and Floaters
New flashes or a sudden increase in floaters from posterior vitreous detachment (PVD) are common symptoms that prompt patients to seek initial eye care. Although PVD is common and often uncomplicated, those presenting with symptoms may have a retinal tear, which can lead to retinal detachment if left untreated by a retina specialist. Even if a tear is not present upon examination, symptomatic patients should be referred promptly. Providers should also take into account risk factors such as lattice degeneration, myopia, previous ocular trauma, and a history of cataract surgery.
If, upon examination, primary eye care providers discover that a tear has already progressed to a retinal detachment, the patient should be referred to a retina specialist immediately to discuss same-day treatment options to preserve vision.
Signs of Fluid Build-Up
Routine examinations also play an important role in monitoring patients with dry AMD for signs of conversion to neovascular AMD. Fluid detected within or beneath the retina is often one of the clearest signs of the development of abnormal blood vessels, which can lead to leakage or bleeding within the macula, placing central vision at risk. If primary care providers suspect AMD has converted, their patient should ideally be evaluated by a retina specialist within days to discuss intervention options.
Progression of Diabetic Retinopathy
Routine examinations are also vital for tracking the development of diabetic retinopathy, which can progress slowly, without noticeable symptoms. In most cases, referral urgency generally increases as retinopathy becomes more advanced or begins to threaten the macula.
Mild or moderate nonproliferative diabetic retinopathy (NPDR) without macular edema can be monitored at appropriate intervals; severe NPDR, proliferative diabetic retinopathy (PDR), and DME warrant retinal evaluation. Clinical guidance generally recommends referral within several weeks for patients with severe NPDR, PDR, or macular edema, depending on the specific findings and level of risk. If proliferative-related complications such as tractional retinal detachment or hemorrhage are found, a referral is generally recommended within 24 to 48 hours.
Knowing When to Monitor and When to Refer
In general, any new symptoms or progressive structural changes that suggest an immediate threat to vision, such as macular involvement, retinal fluid or hemorrhage, or findings consistent with retinal detachment, should prompt clinicians to refer the patient to a retina specialist sooner rather than later. When the appropriate timing is unclear, direct communication between the referring provider and retina specialist can help determine whether a patient should be evaluated routinely, promptly, or on an emergency basis.
Partnering With Northeast Wisconsin Retina Associates
Close collaboration between primary eye care providers and retina specialists helps patients move efficiently between routine monitoring and specialty treatment as their needs change. Northeast Wisconsin Retina Associates works with referring optometrists and ophthalmologists throughout northeastern Wisconsin and upper Michigan to evaluate and manage retinal and macular disease, including AMD, diabetic retinopathy, retinal tears and detachments, and vitreomacular conditions. Our practice also prioritizes prompt evaluation of emergent referrals.
