You got the referral. Maybe your primary care doctor flagged something during a routine visit, or your general eye doctor noticed a change and wanted a specialist to take a closer look.Â
Whatever brought you here, knowing what to expect makes the experience a lot less uncertain.Â
Here is exactly what happens at a retina specialist appointment and why it matters for your vision long term.
Why So Many South Texas Patients Need Retinal Care
The retina is a thin layer of tissue at the back of your eye that converts light into the signals your brain reads as vision. When something goes wrong there, whether from disease, injury, or age, the effects on your sight can be significant and, in some cases, permanent if left untreated.
In South Texas, retinal disease is not a distant concern. It is a community-level reality.
Texas ranks among the top three states in the country for diabetic retinopathy prevalence, with a rate of 5.9 percent of the general population. Diabetic retinopathy, damage to the blood vessels in the retina caused by diabetes, is one of the leading causes of vision loss in working-age adults nationwide.
The stakes are especially high for the Hispanic community. Research published by Prevent Blindness and cited in JAMA Ophthalmology found that Hispanic individuals with diabetes have a vision-threatening diabetic retinopathy rate of 7.1 percent. This is nearly double the 3.6 percent rate seen in white individuals.Â
In a region as predominantly Hispanic as South Texas, that disparity translates to thousands of people who are at elevated risk and may not know it.
The most common reasons patients are referred to a retina specialist include:
- Diabetic retinopathy
- Age-related macular degeneration (AMD)
- Retinal tears or detachments
- Sudden flashes of light or a significant increase in floaters
- Macular holes or macular edema
- Unexplained vision changes your general eye doctor wants a specialist to evaluate
Getting referred does not automatically mean something is seriously wrong. In many cases, your doctor simply wants a more detailed look than a standard eye exam can provide. A retina specialist has the training, tools, and expertise to find out exactly what is happening and to catch problems early, when they are easiest to treat.
What Makes a Retina Specialist Different from Your Regular Eye Doctor
Your optometrist or general ophthalmologist is trained to handle a wide range of eye care needs. But the retina is a specialized area, and conditions affecting it often require a level of diagnostic depth and treatment expertise that goes beyond general eye care.
A retina specialist is a medical doctor who completed four years of medical school, a residency in ophthalmology, and then an additional fellowship specifically focused on diseases and surgery of the retina, vitreous, and macula. That extra training matters because retinal conditions are often complex, frequently linked to systemic diseases like diabetes and high blood pressure, and can progress quickly without proper management.
At Eye Associates of South Texas, both Dr. Sharron Acosta and Dr. J.T. Kavanagh are fellowship-trained specialists who have worked together for over a decade. With more than 30 years of combined experience, they bring the kind of clinical depth that makes a real difference when your retinal health is on the line.
Before Your Appointment: What to Bring and How to Prepare
A little preparation goes a long way in making your visit run smoothly. Before you come in, gather the following:
- Photo ID and current insurance card(s)
- A list of all medications and supplements you currently take, including dosages
- Any known allergies
- Records from your referring doctor, including any imaging, test results, or clinical notes
- Your glasses or contact lenses; vision testing is part of the visit
- A written list of questions or symptoms you want to discuss
The most important thing to plan for: your eyes will be dilated during the appointment. Dilation makes your vision blurry up close and makes your eyes more sensitive to light, and the effects can last several hours.Â
Most patients prefer to bring a driver. If you are driving yourself, plan to wait until your vision has cleared before getting behind the wheel.
First-time appointments typically take two to three hours. Follow-up visits are usually shorter, but it is still smart to build extra time into your schedule. Retinal care is not something to rush.
A Step-by-Step Look at Your Retina Specialist Appointment
Here is what actually happens during a visit, including what each step feels like, not just what it is.
Your Health and Vision History
Your appointment begins with a conversation, not tests. A staff member will ask about your general health, eye health history, any symptoms you have been experiencing, and whether you have a family history of eye disease. This information directly shapes how the doctor approaches your exam.
Your systemic health matters here more than most people expect. Conditions like diabetes, high blood pressure, and high cholesterol all affect the blood vessels in your retina. The more complete and honest your answers, the faster your doctor can build an accurate picture of your eye health.
Vision Testing and Eye Pressure
Next, you will have a standard vision test, the familiar eye chart you have seen at every eye appointment. This gives the doctor a clear baseline for your current visual function.
Your eye pressure will also be measured using a process called tonometry. Depending on the method used, you may feel a gentle puff of air or a very light touch against the surface of your eye. It is not painful, and it only takes a few seconds. Elevated eye pressure can be a sign of certain conditions, so this measurement is a routine part of every visit.
Dilation: What to Actually Expect
Eye drops are placed in each eye to widen the pupils. The drops may cause a brief mild sting as they go in, and within about 20 to 30 minutes, your pupils will be fully dilated.
Once dilated, bright light will feel more intense than usual, and your close-up vision for reading, looking at your phone, or seeing a dashboard will be temporarily blurred. This is completely normal and will resolve within a few hours.
Dilation is not optional or just a formality. Without it, the doctor cannot get an unobstructed view of the retina, optic nerve, and blood vessels at the back of your eye. It is the step that makes everything else possible.
Imaging: OCT and Fundus Photography
Before you see the doctor, a series of imaging tests will be performed. These images give the doctor detailed visual data to review alongside the physical exam.
OCT (Optical Coherence Tomography): This is a non-invasive scan that produces detailed cross-sectional images of the retina’s layers; think of it as an MRI for the back of your eye. You rest your chin on a support, look at a target light, and the scanner does the rest. There is no contact with your eye and no discomfort.
Fundus Photography: A wide-field photograph of the interior of your eye, capturing the retina, optic disc, and blood vessels in a single image. The flash is brief and bright but not harmful.
Fluorescein Angiography (if needed): Some patients require this additional test, which uses a dye injected into a vein in your arm to highlight blood flow through the retinal vessels. The dye travels to your eyes quickly and can temporarily cause your skin to look yellowish and your urine to turn orange for a day or two. This is normal and temporary.
All imaging is completed before your doctor enters the room, so the physician can review your results in real time during the exam.
The Doctor’s Examination
Using a specialized lamp and lenses, the doctor examines your dilated eyes directly. The examination light is bright; many patients find this the most uncomfortable part of the visit, but each eye only takes a few minutes.
Your doctor will review your imaging results alongside the physical exam findings and walk you through what they are seeing in plain language. If a diagnosis is clear, you will hear what it means and what your options are. If more information is needed, additional testing may be recommended.
At Eye Associates of South Texas, the goal is always to make sure you leave understanding your eye health, not just your diagnosis.
What Happens After Your Retina Appointment
For many retinal conditions, the appointment is the beginning of a longer relationship, not a one-and-done visit. Here is what follow-up care typically looks like.
Many retinal diseases are chronic, meaning they are managed over time rather than resolved with a single procedure. Your doctor will outline a monitoring schedule based on the type and severity of your condition. Depending on what is found, that might mean returning every three months, every six months, or once a year.
If treatment is needed, common options include:
Intravitreal injections (anti-VEGF therapy): A common treatment for conditions like macular degeneration and diabetic macular edema. Medication is injected directly into the eye in a quick, in-office procedure. The eye is numbed first, and most patients experience only mild pressure.
Laser treatment: Used to seal retinal tears, slow leaking blood vessels, or address certain stages of diabetic retinopathy. This is also an in-office procedure and is generally well tolerated.
Surgical options: Conditions like retinal detachment or macular holes may require surgery. Your doctor will explain what that involves if it applies to your situation.
Between appointments, there are things you can do to protect your retinal health. If you have diabetes, keeping your blood sugar and blood pressure well managed is one of the most effective things you can do to slow or prevent retinal damage. Wearing UV-protective sunglasses, attending all scheduled follow-ups, and reporting any new symptoms promptly also make a real difference.
Symptoms That Mean You Should Call Sooner Rather Than Later
Most retina appointments are scheduled in advance and are not emergencies. But some symptoms require immediate attention. Do not wait for your next scheduled visit if you experience any of the following:
- A sudden increase in the number or size of floaters in your vision
- A new shower of floaters appearing all at once
- Flashing lights in your vision, especially in a darkened room
- A shadow or dark curtain moving across your field of vision
- Sudden blurry or distorted central vision
These can be signs of a retinal tear or detachment, conditions where time is a critical factor. A retinal detachment is a medical emergency. The sooner it is treated, the better the outcome for your vision.Â
If you are ever unsure whether your symptoms warrant an urgent call, err on the side of calling. Our team would always rather hear from you.
Final Thoughts: Retinal Care That Knows South Texas
There is no shortage of eye care practices in San Antonio, but fellowship-trained retina specialists with deep roots in the South Texas community are a different kind of resource. At Eye Associates of South Texas, Dr. Acosta and Dr. Kavanagh have spent over a decade building a practice focused on comprehensive, effective care for all types of eye disease, retinal conditions included.
Their approach is collaborative by design. Because retinal health so often intersects with a patient’s broader medical picture (diabetes management, blood pressure control, overall cardiovascular health), they work alongside referring physicians to make sure nothing falls through the cracks.
Serving communities throughout South Texas, they understand the specific risk factors this region faces and have built their practice around meeting patients exactly where they are.
