Who are ophthalmologists?
Ophthalmologists are medical doctors offering comprehensive eye care to patients of all ages. Their services include taking eye exams and vision tests, diagnosing and treating eye and vision conditions, and prescribing glasses or contact lenses. They are also qualified to conduct eye surgeries if needed. Many run their private practice or work in hospitals.
Ophthalmologists undergo several years of education and training before they get their medical license. They earn a four-year bachelor's degree and a four-year medical degree. After their education, they complete a one-year internship and a three-year ophthalmology residency program. Some may opt for 1-2 years of fellowship training to further specialize in their desired field, such as cornea, retina, glaucoma, pediatrics, oculoplastics, or neurology.
Subspecializations within ophthalmology
Each subspecialty focuses on specific aspects of eye care. Some of the key subspecialties of ophthalmology include:
- Cornea: Cornea refers to the transparent, dome-shaped layer situated in front of the iris and pupil. Corneal subspecialists diagnose and treat disorders like Fuchs' dystrophy and keratoconus. Additionally, they perform refractive surgeries like LASIK and corneal transplants, manage corneal trauma, and conduct intricate contact lens fittings.
- Retina: It is a light-sensitive layer at the rear of the eye. Within it lies the macula, pivotal for central, detailed vision. Retina specialists diagnose and treat ailments like macular degeneration and diabetic eye disease. They conduct surgeries to mend torn or detached retinas and address issues with the eyeball's vitreous, gel-like substance.
- Glaucoma: Glaucoma results from high pressure in the eye and impacts the optic nerve linking the eye to the brain. When fluid fails to circulate adequately within the eye, pressure accumulates, leading to optic nerve damage. Glaucoma specialists employ medications, laser therapy, and surgical interventions to regulate intraocular pressure and preserve vision.
- Pediatrics: Pediatric ophthalmologists specialize in addressing eye disorders in infants and children. Their range of treatment covers eye misalignment, including strabismus, uncorrected refractive errors, etc. They also manage childhood eye ailments and diverse conditions. Strabismus specialists also extend their expertise to adults experiencing ocular coordination issues.
- Oculoplastic: Oculoplastic surgeons cater to problems affecting the eyelids, bones, and adjacent structures, including the tear drainage system. They administer medical injections around the eyes and face to optimize facial structure, aesthetics, and function.
- Neurology: Neuro-ophthalmologists specialize in managing vision issues stemming from interactions between the eyes, brain, nerves, and muscles. They diagnose and manage diverse conditions such as optic nerve disorders, vision impairments, diplopia, abnormal eye movements, anisocoria, and eyelid abnormalities.
Even though an ophthalmologist can take care of all aspects of eye care, the inputs of subspecialists help patients get tailored treatment related to a specific part of the organ.
How is an ophthalmologist different from an optometrist?
Ophthalmologists and optometrists are both specialists in eye care, but their roles differ.
- Ophthalmologists: These providers are medical doctors (MDs) or Doctors of Osteopathy (DO) who have completed medical school. They are qualified to diagnose and treat all eye conditions and can perform eye surgery.
- Optometrists: These providers hold a Doctor of Optometry (OD) degree. They can diagnose and treat many eye issues, but they do not perform eye surgeries. If an optometrist identifies a condition that requires surgery, you will need to get the treatment from an ophthalmologist.
What do ophthalmologists treat?
When you visit an eye doctor near you, they will offer medical and surgical treatment for various common and serious eye conditions, including:
- Age-related macular degeneration: This progressive eye disease affects the retina's central part and eventually causes vision loss.
- Amblyopia, or lazy eye: This is a developmental vision disorder that affects vision in one or both eyes.
- Diabetes-related retinopathy: This is a diabetes complication affecting the blood vessels in your retina, causing visual impairment, and when left untreated, it can cause blindness.
- Refractive errors: These include nearsightedness, farsightedness, astigmatism, and presbyopia. They all cause blurry vision, making it hard for the eyes to see clearly.
- Posterior vitreous detachment (PVD): A process of aging; it is when the gel-like substance in the back of the eye, called the vitreous, separates from the retina. It can cause floaters, flashes of light, or a curtain-like shadow in the visual field.
- Dry eye: This is a common ailment identified by insufficient moisture or lubrication on the eye's surface, causing discomfort, redness, itching, and blurred vision.
- Glaucoma: Refers to conditions associated with high eye pressure that can cause optic nerve damage, leading to vision loss or blindness.
- Cataracts: The condition causes clouding of the eye lens, leading to blurred vision.
What to expect when visiting an ophthalmologist?
Your first visit will usually begin with an initial consultation, during which your ophthalmologist will gather your detailed medical history. This includes basic personal information, medical background, and any relevant eye health history.
Following the consultation, they may perform a series of vision tests to evaluate your eyesight and determine any corrective measures that may be needed. These tests include checking your visual acuity, screening for color blindness, and assessing how well your eyes move and work together.
Next, your ophthalmologist will conduct a comprehensive eye examination, which involves:
- External Examination: Examining the outer parts of your eyes, including the eyelids and surrounding tissues.
- Slit-Lamp Examination: Using a specialized microscope to inspect the front structures of your eye, such as the cornea, iris, and lens.
- Retinal Examination: Dilating your pupils to examine the retina, optic nerve, along with the blood vessels at the back of your eye.
- Tonometry: Measuring the internal pressure of your eyes to check for signs of glaucoma.
After the examination, your ophthalmologist will explain any conditions you may have and discuss treatment options and preventive measures. It is important to ask any questions you have about your eye health and ways to improve it.
What is eye cancer?
A tumor or malignancy that begins and spreads in your eye is called eye cancer. It is a collection of cancer cells that expand rapidly and uncontrollably. They may infiltrate and damage tissues or spread to other locations in the body.
The eye comprises three major parts, i.e., the eyeball, orbit, and adnexal structures. The eyeball is made up of vitreous humor, a jelly-like fluid. It consists of three layers:
- The outer layer: Sclera
- The nourishing layer: Uvea
- The layer that sends information to the brain: The retina
The orbit consists of the bones and tissues surrounding the eyeball to help move the eyes and the nerves attached to it, while the adnexal structures are the eyelids and tear glands.
Types of eye cancer
The eye cancer type depends on where it has developed. The following are the most common eye cancer classifications:
- Primary and secondary intraocular cancers
- Primary intraocular cancers are those that start in the eye, and secondary intraocular cancers are those that begin elsewhere and spread to the eye. The most common intraocular cancers are Melanoma and non-Hodgkin lymphoma in adults and Retinoblastoma and Medulloepithelioma in children. Lung and breast cancer are the most recurrent tumors that spread to the eye. The uvea, a portion of the eyeball, is where these tumors most frequently metastasize.
- Orbital and adnexal cancers
- Like tumors in other body parts, the orbit and adnexa around the eyeball grow from tissues like muscle, nerve, and skin.
Symptoms of eye cancer
Symptoms of eye cancers are generally not observed till cancer spreads to a specific part. Moreover, symptoms are so common that they can be mistaken for other conditions. The most common symptoms of eye cancer are:
- Blurry vision
- Bulging of one eye or lump in the eyelid
- Sudden loss of vision
- Shadows or flashes of light, or spots or floaters in the field of vision
- Pain in and around the eyes
- Increasing dark spots in the colored part of the eye
- Change in the pupil's size and shape and the eyeball's position
Diagnosis of eye cancer
You must promptly visit an ophthalmologist near you if you suffer from eye cancer symptoms. An ophthalmologist is an eye care expert who diagnoses and treats eye and vision-related problems.
They use several tests to check if cancer has spread to another body part. While the biopsy is a commonly used method for diagnosing most cancers, specialists may also recommend the following tests:
- Regular eye examination and ultrasound: Eye doctors generally diagnose melanomas during a comprehensive exam. An ophthalmoscope examines the patient's eyes, while an ultrasound produces a picture of the eye.
- Fluorescein or indocyanine green angiography: The procedure uses fluorescent dyes (fluorescein or indocyanine green) to take images of the blood vessels in the eyes. The dye is injected through the arm and then moves through the body into the blood vessels. The doctor takes several pictures in the estimated time. The procedure helps to rule out other eye conditions.
- Fine needle biopsy: The tumor cells in the eye are removed with the help of a needle and examined under a microscope.
- Cytogenetics and gene expression profiling: The test collects information about the chances of treatment and recovery using a tissue sample recovered during biopsy or surgery.
- Tests for metastases: It is essential to test if the tumors developed in the eyes have spread to other body parts. The procedures used to test metastases are computed tomography or CT scan, magnetic resonance imaging (MRI), and positron emission tomography or PET scan.

Statistics overview of eye cancer in the United States and Texas
According to the American Cancer Society, the risk of eye cancer rises after age 50. People with light eyes and fair skin are at a further increased risk of developing eye cancer. Furthermore, primary eye malignancies are more common in men than women. The Society estimates approximately 3,360 new cancer cases (mainly melanomas) and around 410 eye and orbital cancer deaths in the USA in 2022.
The most frequent kind of eye cancer in children is retinoblastoma, accounting for 3% of childhood cancers. According to a 2015 Texas Children's Hospital survey, the estimated incidence rate of retinoblastoma was 1 in 15,000 live births, meaning that 26 cases would be diagnosed yearly in Texas. And nearly half of those cases would occur among infants in rural areas of the state.
