What is an ophthalmologist?
An ophthalmologist is a doctor specializing in vision and eye care. They undergo training and obtain licensing to diagnose and treat all eye-related conditions, perform surgeries, and prescribe medications.
People often need clarification from an optician, optometrist, and ophthalmologist. Although the terms are similar and the job descriptions overlap significantly, the three differ based on their degree and training.
Ophthalmologists are licensed medical doctors who diagnose eye problems and treat them through eye exams, surgeries, or medications. They also provide prescriptions for glasses or contact lenses. Optometrists are eye care professionals with optometry degrees. They are trained to examine eyes, test vision, prescribe lenses or glasses, and diagnose eye disorders. Although they are not medical doctors, they can prescribe medications for several eye diseases.
Opticians are not medical professionals. Technicians design and verify all eyesight-correcting devices, including glasses and contact lenses. They are prohibited from testing eye vision or prescribing medications to correct eye diseases. Hence, they use the prescriptions provided by professionals like optometrists or ophthalmologists.
In the United States, a person must complete around 12 years of education and training, including four years of college, four years of medical school, and 4 to 5 years of additional training or specialization studies, to qualify as an ophthalmologist.
An ophthalmologist treats common eye conditions such as cataracts, glaucoma, amblyopia or lazy eye, squint, retinal swelling, retinal bleeding, retinal detachment, corneal pathology, and intraocular inflammation. They can also treat eye injuries, macular degeneration, rare diseases (such as bloody tears), and diabetic retinopathy.
Ophthalmology subspecialties
After collecting their degrees and certifications, ophthalmologists may pursue additional training lasting one or two years. These subspecialties allow them to hone their expertise and contribute to specialized areas of eye care. Some of the subspecialties are:
- Cornea and external disease: Professionals in this subspecialty focus on treating the visible parts of the eye, including the eyelids. Their expertise extends to addressing conditions that impact these external components.
- Glaucoma: Ophthalmologists specializing in glaucoma delve into treating this condition and other disorders that may lead to optic nerve damage. Notably, glaucoma has no cure. Treatment for the condition goes for life, even though surgery is sometimes required to eliminate or reduce the need for treatments like eye drops.
- Neuro-ophthalmology: This subspecialty concentrates on the intricate interplay between the optic nerves, visual pathways, and the connection between neurological and ophthalmic diseases. Neuroophthalmologists may prescribe tests like optical coherence tomography, electroretinography, and multi-focal ERGs.
- Ophthalmic pathology: Professionals specializing in ophthalmic pathology analyze tissue specimens from the eye and surrounding structures.
- Ophthalmic plastic surgery: Focused on aesthetic and functional aspects, this subspecialty encompasses facial plastic surgery, eyelid surgery, orbital (eye socket) surgery, and lacrimal (tear duct) surgery.
- Pediatric ophthalmology: Pediatric ophthalmologists address a broad spectrum of eye conditions in children, including genetic, developmental, inflammatory, traumatic, and other issues.
- Vitreoretinal diseases: Ophthalmologists in this field specialize in surgical interventions to address diseases affecting the retina and vitreous, the interior of the eye. Vitreoretinal disorders include retinal tears, macular degeneration, retinal detachment, diabetic retinopathy, and macular holes.
- Uveitis: Specializing in treating inflammation inside the eye, uveitis experts are pivotal in managing conditions arising from the immune system's response. It includes instances where the immune system fights an infection or mistakenly attacks healthy eye tissue, as the National Eye Institute noted.
Why should I see an ophthalmologist?
If you experience eye irritation, infection, watery eyes, or severe headache, you should visit an ophthalmologist near you to diagnose the problem. However, the American Academy of Ophthalmology recommends regular baseline exams for children as their eyes change rapidly. An adult with healthy eyes and perfect vision should have four comprehensive eye examinations, i.e., one in the 20s, two in the 30s, and one at 40.
Regular eye checkups allow early detection of eye diseases or vision loss, which helps protect your eyesight because the symptoms are often realized later. Moreover, people more vulnerable to eye problems, such as those with a family history of eye diseases and those with diabetes or high blood pressure, must get their eye checkups more often. People who use contact lenses or glasses should get a comprehensive eye exam every year, regardless of age.
When should I visit an ophthalmologist?
Sometimes, your optician or optometrist will refer you to an ophthalmologist. Moreover, there are several symptoms that you should be careful about. You should visit an ophthalmologist if you observe any of the following symptoms: eye pain, headache, irritation in the eyes, decreased vision, light flashes, halos around the lights, seeing spots or random images, crossed eyes (esotropia), double vision (diplopia), dry eyes, edges or straight lines appearing wavy, eye discharge or tears, sudden vision loss, blurriness, night blindness, bulging of the eye(s), injury to the eye, and in case of family history of eye disease.
Moreover, many health conditions increase vulnerability to eye diseases. For instance, diabetic patients are at risk of diabetic retinopathy, and high blood pressure can also lead to loss of sight.
Tips for choosing an ophthalmologist
We rely on ophthalmologists for the most sensitive part of our bodies, the eyes. Their experience and specialization can fill the gap between blindness and vision. It is a common saying that the eyes are the windows to your soul, but it is also true that they are the windows to your body.
Several conditions are missed by a general physician but are detected by ophthalmologists during an eye exam. So, if you are looking for an ophthalmologist for you, or your friends or family, make sure you consider the following points:
- Be sure to see an ophthalmologist near you for a comprehensive eye exam, not an optometrist or optician, for your eye prescription or vision test.
- Crosscheck the credentials of the selected ophthalmologist on the American Board of Ophthalmology or the American Board of Medical Specialties websites.
- Ask your family doctor or optometrist for specific referrals.
- Try booking an appointment with an ophthalmologist with more experience, especially when your eyes need careful procedures or surgeries.
- Do some background research about your condition and look for an ophthalmologist specializing in that condition. For example, some ophthalmologists might specialize in LASIK surgery, and some might specialize in treating a specific disease like glaucoma or diabetic retinopathy.
- Lastly, select a team and environment that makes you most comfortable.
Which conditions can be detected by eye exams?
Eye exams are essential for detecting and diagnosing many different diseases. Some of the more common concerns that can be identified during an eye exam include the following:
- Glaucoma is an optical disorder that damages the optic nerve, which is crirical for good vision. The common type of glaucoma is primary open-angle glaucoma, which gradually reduces peripheral (side) vision. If untreated, glaucoma can lead to blindness. There are several other types of glaucoma, including angle-closure glaucoma, that occurs when the iris blocks the angle of drainage situated between the iris and the cornea; normal-tension glaucoma, characterized by optic nerve damage despite intraocular pressure being within the normal range; and pediatric glaucoma, a rare form that affects children.
- Macular degeneration: Macular degeneration is an ocular problem resulting in the deterioration of the macula, the small central area of the retina that improves sharp and central vision. Macular degeneration can make reading, driving, or seeing fine details difficult. There are two kinds of macular degeneration—wet and dry. Dry macular degeneration is the typical type and occurs when the macula cells slowly break down. Wet macular degeneration occurs when extra blood vessels beneath the retina proliferate and leak blood or fluid. This type can cause rapid vision loss and is considered to be more severe than dry macular degeneration. While there is no cure for macular degeneration, various treatments can decelerate its advancement and aid in maintaining vision. If you have concerns about your idea, talk to your eye doctor during your next routine eye exam.
- Cataracts: Cataracts are a common age-based eye condition that causes the eye's lens to become cloudy, making it difficult to see. Your doctor or optometrist can detect cataracts during an eye exam.
- Diabetic retinopathy: Diabetic retinopathy is a complication linked to diabetes that can damage retinal blood vessels, the light-sensitive tissue at the back of the eye. If not addressed, it leads to blindness. An annual comprehensive dilated eye exam is the most effective way to detect and treat this disease before vision loss occurs.
How do you keep your eyes healthy?
Here are some easy tips to keep your eye health optimal:
- Feed yourself well: A balanced and nutritious diet is the foundation of good health. It should include all the essentials, from a good amount of fruits and vegetables to fish and protein. By the way, deep yellow and green leafy vegetables and omega-3 fatty acid-rich fish like tuna, salmon, and halibut are known for improving eye health.
- Keep an eye on your weight: A healthy weight prevents diseases. Experts underscore that being overweight or obese is a significant risk factor for diabetes, which sometimes leads to glaucoma or diabetic retinopathy. Hence, regularly working out is essential.
- Protect your eyes: Excessive sun exposure can cause age-related macular degeneration and cataracts. Use sunglasses that block 99 to 100% of UV-A and UV-B radiation whenever you step out. Also, certain activities like sports, factory work, construction, and house repairs can sometimes lead to eye injuries. So, wearing protective eyewear in such cases helps prevent these.
- Quit or avoid smoking: Smoking, in the long run, damages the optic nerve that is vital for vision and raises the risk of macular degeneration and cataracts, harming your eye health. Quitting is the best option.
- Give your eyes rest: Spending a lot of time on the screen lessens the frequency of your blinking, leading to tired eyes or eye strain. That's why you should not forget to give them the rest they deserve after all they do for you every day!

Vision health statistics in Texas
In the United States, around 12 million people 40 years of age or older have vision impairment. In 2016, the National Federation of the Blind published the state distribution profile for visual disability. This state distribution profile reported 702,500 individuals (non-institutionalized, male or female, regardless of age and education levels) with vision disability in Texas. Moreover, according to prevalence rates of vision difficulty by the American Foundation for the Blind, 695,054 individuals in Texas had vision impairment in 2019.
According to VisionCenter 2018 data, approximately 6.21% of people in Texas reported having difficulty seeing even with glasses or being blind. Roughly 4.38% were aged between 18 and 39, 6.51% were aged between 40 and 64, and 9.71% were aged above 65. Also, out of the 6.21% of the general population experiencing symptoms, around 14% had diabetes, and the percentage was higher among individuals who smoked tobacco, at 10.1%. This suggests that smoking elevates the risk of vision problems by about 4%.
