Who is an ophthalmologist?
An ophthalmologist is a specialist who diagnoses, treats, and helps prevent vision issues and eye diseases. They can recommend and fit contact lenses and eyeglasses and perform eye surgery. In addition to hospitals and clinics, they may work in research departments, seeking cures for problems with vision or eye diseases, or teach in universities and medical schools.
Ophthalmologists are medical doctors; hence, they can detect diseases in other body parts or diagnose chronic illnesses as their symptoms often manifest in the eyes first. Because of their experience, they can identify these illnesses in their earliest stages and refer you to the right specialist. That is why it is necessary to visit an ophthalmologist regularly.
What kind of education and training does an ophthalmologist receive?
To become an ophthalmologist, one must complete their undergraduate studies before enrolling in medical school. Medical school requires four years of learning subjects such as pharmacology, medical laws, anatomy, physiology, biochemistry, and ethics. The first two years involve studying theory, while for the next two, students learn how to diagnose and treat illnesses in settings such as hospitals and clinics. On completing medical school, they receive a Doctor of Medicine (MD) or Doctor of Osteopathy (DO) degree.
Next, doctors must do a one-year internship in ophthalmology. Direct patient care is the main focus of this internship in a specialty like emergency medicine, family medicine, internal medicine, neurology, or surgery. The next step is a residency, where doctors study and train in classrooms and clinical settings. They train how to diagnose and treat illnesses and conditions of the eyes, how to perform eye surgery, and provide post-surgical care. While many ophthalmologists take up practice after residency, others prefer to specialize further by doing a fellowship in a subspecialty.
To begin practicing, ophthalmologists must clear a stringent state-level licensing examination conducted by the Comprehensive Osteopathic Medical Licensing Exam (COMLEX) or the United States Medical Licensing Examination (USMLE). One can also get a board certification from the American Board of Ophthalmology (ABOP) or the American Osteopathic Board of Ophthalmology (AOBOO).
What are the subspecialties in ophthalmology?
Specializations allow ophthalmologists to treat complex conditions in particular parts of the eye or specific types of patients. Some subspecialties in ophthalmology include:
- Pediatric ophthalmology: Focuses on treating children by offering diagnostic examinations, checking for eye conditions, carrying out surgeries, and tending to wounds.
- Ophthalmic pathology: This field treats conditions that can harm the eye and nearby tissues. It involves analyzing and treating tissues from the eyes and ocular adnexa. These problems may result from eye or orbit cancer or conditions such as renal disease or diabetes, which affect the eyes.
- Uveitis and ocular immunology: This field deals with diagnosing and treating ocular inflammatory diseases caused by uveitis. These ophthalmologists have advanced training in identifying and caring for patients with inflammatory eye diseases.
- Ophthalmic reconstructive and plastic surgery: It involves repairing damage caused by illness, fracture, or evisceration. These reconstructions include the eyelids, eye sockets, tear ducts, eyebrows, and midface.
- Neuro-ophthalmology: This specialty treats vision problems caused by neurological issues such as strokes or traumatic brain injury. Glasses, surgery, or rehabilitation are some of the treatments for this specialty.
Other subspecialties include corneal and external eye disease, vitreoretinal diseases, and glaucoma.
Ophthalmologist vs. optometrist
While both optometrists and ophthalmologists play crucial roles in eye care, they have apparent differences.
Optometrists focus on primary vision care and perform comprehensive exams to evaluate eye health and vision quality. This includes vision screenings and testing, prescribing contact lenses and eyeglasses, and offering minor procedures like removing foreign bodies from your eye. Additionally, they can detect underlying health issues that may affect your eyes. However, they are not medical doctors and cannot perform complex surgery and offer other specialist care.
On the other hand, ophthalmologists are responsible for examining and treating all eye ailments, from minor discomforts to more severe conditions that could lead to partial or total blindness. They prescribe medications and conduct surgical procedures such as cataract surgery and glaucoma surgery, among many others. They also recommend eyewear and contact lenses to correct vision problems.
As for their educational differences, optometrists earn a Doctor of Optometry (OD) degree after 2-4 years of college and four years of optometry school.
Meanwhile, ophthalmologists invest 12 to 14 years to get a medical degree (MD). They are the only eye doctors with such a degree. Some of them choose to specialize in areas such as pediatric ophthalmology, neuro-ophthalmology, oculoplastic surgery, and vitreoretinal surgery.
By understanding the roles of each eye care professional, you can make more informed decisions about your visual health and find the proper care for your needs.
What are cataracts, and what are the risk factors?
A cataract is an age-related issue that causes the eye lens to cloud. Although one can treat this problem with cataract surgery, many worldwide do not have access to this procedure. Cataracts are responsible for half the world's blindness. Cataract surgery has low risks and complications; millions of such operations occur annually in the United States. It is also the most frequent type of eye surgery in the United States, especially for those over 65.
Women are more likely to have cataracts than men. Moreover, smoking, diabetes, certain steroids and medications, and overexposure to sunlight increase the risk of cataracts. It can cause difficulty reading or driving, cloudy vision, impaired color vision, double or blurry vision, and sensitivity to bright lights.
Computers, digital devices, and eye strain
You might have come across the notion that extended periods of staring at digital screens, such as computers, smartphones, and other devices, will cause permanent damage to your eyes. While this is only partially accurate, it doesn't change the fact that prolonged screen time can lead to feelings of discomfort and strain if not cause permanent damage.
Digital eye strain occurs because our blinking rate decreases when we fixate on our devices. On average, humans blink approximately 15 times per minute, but this blink rate can be reduced by half when we focus on screens.
The effects of digital usage on eye strain are universal, affecting people of all ages. However, it's worth noting that this phenomenon is often particularly noticeable among children.
Suppose you or your child spend extended hours daily engrossed in digital devices. In that case, you might experience symptoms like blurry vision, a sense of fatigue and discomfort in the eyes, dryness, stinging in the eyes, and tears.
Suppose your child complains of any of these symptoms. In that case, it's a signal to consider seeking out a pediatric eye doctor near you. As our reliance on cell phones and computers is unlikely to diminish anytime soon, how can we alleviate the eye strain associated with digital use? Here are some suggestions to help ease the stress on your eyes:
- Keep your eyes moist: Although blinking is the natural mechanism for maintaining adequate eye moisture, employing artificial tear drops is also a practical approach to achieve the same result. They help refresh your eyes when they feel dry and achy.
- Take frequent breaks: In the post-COVID-19 era, online classes have become the norm. While this shift offers several advantages, it also brings with it prolonged screen time for children. Notably, research indicates that children with digital devices for more than five hours during the lockdown faced an elevated risk of experiencing digital eye strain. Integrating regular breaks into their routine is imperative to address the potential strain on your child's eyes and overall well-being. Please encourage them to stand up, stretch, and redirect their gaze away from the screen. These breaks significantly relieve eye strain and uphold productivity and health amidst the changing education landscape.
- Adjust your position: While working on the computer, maintain a distance of approximately 25 inches from the screen, which conveniently aligns with the length of your arm. Furthermore, position the screen in a way that prompts your eyes to look slightly downward, avoiding a direct line of sight. This optimal setup promotes comfort and minimizes the strain on your eyes and neck.
In light of the significant impact digital devices can have on our eyes and overall well-being, it's evident that adopting strategies to mitigate their effects is essential. However, it's equally important to consider the broader aspect of maintaining overall eye health beyond these immediate measures. Regular eye examinations are pivotal in this endeavor, allowing us to proactively monitor our vision and address emerging concerns before they escalate. This information brings us to our next question – how often should one get an eye exam?
How often should one get an eye examination?
Getting your eyes checked regularly is extremely important. We generally get an eye examination only when we have a vision problem. However, a regular eye checkup with an ophthalmologist near you can detect eye problems and other chronic conditions such as diabetes and high blood pressure. Detecting these conditions means getting early treatment before they cause severe damage to the body.
If you or a family member has a history of eye issues, you should visit an ophthalmologist for routine checkups. The American Academy of Ophthalmology recommends that one must have a complete medical eye exam done by age 40. After that, the ophthalmologist will advise you when to complete the next test.
Tests performed by an ophthalmologist
The ophthalmologist will begin the examination by asking about the patient's medical history, including details about their family's eye health. Once this information is gathered, the eye examination will begin with a series of tests to assess vision and eye health.
Visual acuity test
The patient will stand 20 feet away from a Snellen chart, with one eye covered at a time, and read the letters. This test helps the ophthalmologist evaluate how clearly the patient can see at different distances.
Visual field assessment
This test measures the extent of the patient's vision, identifying any blind spots or conditions that could affect sight. It includes methods like the confrontation visual field test, automated static perimetry, and Amsler grid.
Eye pressure testing (Tonometry)
Eye pressure is checked to detect potential glaucoma. The ophthalmologist may use several techniques, such as application tonometry (which uses a handheld device), non-contact tonometry (using a puff of air), rebound tonometry (measuring corneal resistance), or indentation tonometry (using a Tono-pen device).
Eye movement test (ocular motility)
This test checks for proper eye alignment and muscle function. The patient follows a moving target to ensure the eyes are working together correctly.
Assessment of the eye's front, retina, and optic nerve
The ophthalmologist will use a slit-lamp microscope to examine the front of the eye and a lens to inspect the retina, macula, and optic nerve. Eye drops may be applied to dilate the pupil for a more detailed examination, though they can also assess without dilation.
Prescription for eyeglasses or contact lenses
The patient will look through a phoropter containing different lenses to determine the correct prescription for vision correction.
Additional tests
Depending on the need, further tests such as optical coherence tomography (OCT), fundus photography, corneal topography, or fluorescein angiography may be recommended. Fluorescein angiography involves injecting dye into the bloodstream to take detailed pictures of the retina.

Statistics on vision loss in California
According to the Centers for Disease Control and Prevention (CDC), in 2015, approximately 1.02 million people in the United States were blind, and about 3.22 million had vision impairment (VI). Furthermore, 8.2 million people had VI due to uncorrected refractive error. According to projections, by 2050, roughly 2.01 million people will be blind or have a VI of 20/200 or worse, 6.95 million people will have VI, and 16.4 million people will have VI because of uncorrected refractive error.
The same source also reports that in 2017, 2.04% of California's population was diagnosed with vision loss. The incidence of partial or total vision loss increased with age, with 20.35% of those 85 and older diagnosed with the condition. It was followed by those aged 65 to 84 with a 6.36% chance of suffering from vision loss. The percentage was lower in those aged 40 to 64 (1.22%), 18 to 39 (1.04%), and those below 18 (0.81%). Additionally, the incidence was higher in women (2.38%) than in men (1.69%).
