What do optometrists do, and how are they different from ophthalmologists?
With every hour spent watching electronic screens that project harmful blue rays, people are more prone to contracting various eye conditions. Due to reasons like the overuse of electronic devices, the best eye care practices have become the need of the hour. A regular eye checkup is necessary to maintain good eye health. Optometrists and ophthalmologists are healthcare practitioners who specialize in treating eye and vision disorders.
While ophthalmologists earn a degree in medicine and then specialize in eye care, optometrists earn a four-year degree followed by one year of training. Optometrists can specialize further in a particular part of the eye, like the cornea or the retina. While ophthalmologists are well-equipped to perform surgical procedures, optometrists can only provide non-surgical assistance.
Upon obtaining a Doctor of Optometry (OD) degree and securing licensure, optometrists can pursue additional education and training in specific areas of optometry. This specialized training enables them to develop expertise in particular domains, providing focused and meticulous treatment for their patients.
Subspecialties within optometry
While searching for eye doctors near you, you may encounter professionals with some particular specializations, along with their qualifications. Understanding the nature of these specializations and how each doctor can address your needs is helpful. It helps you choose the most suitable practitioner to treat your medical issue. Various optometric fields include-
- Low vision - Optometrists in this field specialize in addressing visual impairment when conventional interventions like surgery, eyeglasses, or contact lenses prove insufficient. They undergo training in utilizing medical instruments and advanced technologies to assist and treat individuals with low vision.
- Ocular disease - Optometrists in this specialization treat conditions affecting both the front and back portions of the eye, including macular degeneration and glaucoma. They also employ diverse treatment methodologies to address ocular diseases.
- Pediatric optometry - Focusing on vision problems affecting infants, children, and adolescents, pediatric optometrists offer regular eye examinations, vision therapy, and diagnosis and treatment of binocular vision issues explicitly designed for children's comfort and health.
- Geriatric optometry - Targeting healthcare for individuals aged 60 and above, optometrists in this field conduct eye checkups and address common age-related eye issues such as cataracts, diabetic retinopathy, and macular degeneration.
- Cornea and contact lens - Optometrists specializing in this field diagnose and treat conditions affecting the cornea—the outer transparent layer of the eye. They also assist in fitting personalized and specialized contact lenses.
- Neuro-optometry - Dealing with vision issues associated with neurological problems, optometrists in this specialization diagnose, manage, and treat conditions such as vision loss resulting from neurological diseases, congenital factors, and trauma-related causes.
Understanding these specializations will allow you to select the best optometrists near you who can efficiently address your needs.
Role of optometrists
Optometrists provide patients with immediate and primary eye care and pre- and post-surgery eye and vision care. They help patients identify various eye disorders or vision problems and find remedies. Optometrists usually start by conducting general eye examinations, after which they analyze the patient's medical history related to eye problems. They try to understand various factors contributing to eye disorders or vision problems. Once they detect a certain kind of eye disorder or vision problem, they prescribe medication or eyeglasses to help resolve the condition.
Various eye disorders optometrists deal with -
- Glaucoma: Glaucoma is a severe eye condition in which the critical optic nerve for good vision is damaged. Although various eye disorders can cause optic nerve injury, high eye pressure is the most common cause. Glaucoma is often hard to detect, as many forms have no warning signs. Untreated glaucoma leads to severe vision loss, which is hard to recover. When caught early, specialists can slow down and manage this condition with proper eye care.
- Color blindness: Color blindness, also known as a color deficiency, is a vision condition that occurs when one cannot view colors in a usual way or when one cannot distinguish between specific colors. The retina has two cells, namely rods and cones. Color blindness or color deficiency can occur when one or more cone cells are absent or malfunctioning. Although Color blindness is incurable, treatment can assist. Symptoms of colourblindness include light sensitivity, poor vision, and inability to distinguish between specific colors.
- Floaters: Floaters or eye floaters are spots in vision that may look like black or gray strings or cobwebs. Floaters are often the result of age-related changes. Age-related changes in the eye can occur as the jelly-like substance inside the eyes turns more liquid. Microscopic fibers within the eye can cast blocks or shadows on the retina. The clouds that happen are called floaters. If a person suffering from eye floaters experiences a sudden increase in floaters, they should seek immediate eye care from an optometrist or an ophthalmologist.
- Nearsightedness: Nearsightedness, or myopia, is a common vision condition that has affected people worldwide. The situation might develop gradually or rapidly and worsen during life's early stages. If your family has a history of nearsightedness, then you may also experience myopia at some point. Optometrists perform essential exams to confirm if a patient has myopia. Once the condition is confirmed, optometrists suggest eyeglasses, contact lenses, or refractive surgery to compensate for the blurry vision.
When should you see an optometrist?
Taking care of eye health and vision health is very important these days. Apart from routine eye checkups, you should visit an optometrist near you if you:
- Have trouble focusing on one object
- You can't see things near your eyes or far from your eyes.
- Have difficulty reading
- Experience discomfort inside or outside your eyelids
- Have a burning sensation in your eyes.
- Persistently squint when trying to look at nearby objects.
- Blink excessively and rub your eyes frequently.
- Have swollen eyelids or eyes
- Have gray cloud-like structures forming in your eyes
- Have blurry vision
What should you expect during an eye exam?
Eye exams help in the early detection of eye issues when they are most amenable to treatment. Your eye care provider may assist you in adjusting to vision changes or correcting them with regular eye exams. They may also guide you on how to care for your eyes. Furthermore, results from an eye test might provide details about your overall health.
You should be well-prepared for your meeting with the optometrist. Your optometrist may inquire about your vision problems, ongoing medical conditions, medication lists, and family eye health history. Be prepared with an explanation of these factors. Additionally, if you use glasses or contact lenses, bring them to the appointment.
After learning about your health and vision history, the eye doctor will do a complete eye exam, including various tests to establish your overall eye health. Depending on the number of tests, you may expect your appointment to last a half hour or longer. Some of the standard exams include:
- Tests for visual acuity (determines refractive errors of eyes such as nearsightedness and farsightedness)
- Eye muscle test (measures the degree of eye muscle weakening that can lead to unintentional eye movements)
- Pupil response (Assesses pupil reflexes)
- Pupil dilation (identifies the common eye disorders, including glaucoma, diabetic retinopathy, and age-related macular degeneration)
- Cover test (inspects the eyes for deviation)
- Slit lamp exam (examines eye structures such as the cornea, iris, eyelids, lens, and lashes)
- Retinal examination (evaluates the structures around the retina and the rear of the eye)
Following the eye exams, your optometrist will discuss the findings with you to devise an appropriate treatment plan. For instance, they may prescribe glasses or contact lenses to address refractive faults. They could also offer preventative advice for good eyesight, such as eating well, giving your eyes regular breaks, keeping a healthy weight, avoiding smoking, and other methods of eye care.
What your eyes reveal about your health
Your eyes can often signal underlying health issues that go beyond vision problems. Optometrists and healthcare professionals can detect early warning signs of systemic conditions through a comprehensive eye exam. Changes in your vision or eye appearance may indicate anything from minor issues to more severe health concerns. Here's what different eye symptoms might reveal about your health:
- Night blindness: Difficulty seeing in low light may mean you need glasses or have cataracts, which are common as you age. In rare cases, particularly in poorer regions, night blindness could result from a vitamin A deficiency. This is treated with vitamin supplements or a diet rich in vitamin A, including sweet potatoes, beef liver, and spinach.
- Yellowing of the whites of your eyes: Yellow eyes, or jaundice, typically indicate liver problems, as high bilirubin levels cause discoloration. Liver inflammation or damage can result from a poor diet, infections, cancer, or chronic alcohol abuse. Treatment ranges from lifestyle changes to medications or liver transplants.
- Sudden blurry vision: If you have a sudden loss of vision, it may indicate an issue with blood flow to your eyes or brain. Seeking timely medical assistance is critical to avoiding serious injury and potentially saving your life. Even if your vision clears up quickly, it could still be a warning sign of a stroke or the onset of a migraine.
- Drooping eyelids: It can be a sign of myasthenia gravis, an autoimmune disorder that weakens muscles, especially in the eyes, face, and throat. It can make chewing, swallowing, or speaking difficult. While medication and blood filtration can help, they offer only temporary relief. The thymus gland may also need to be surgically removed.
- Bulging eyes: Graves' disease can cause your thyroid gland to produce excess hormones, leading to bulging eyes, double vision, or vision loss. It may also result in symptoms like diarrhea, weight loss, and hand tremors. While medication or surgery can help regulate hormone levels, they won't cure the disease and may not fully address your eye symptoms.
- Ring around your cornea: The corneal arcus, which causes a grey-white line of fat deposits around the cornea, can sometimes form a complete ring. If you're over 40, this is usually harmless. However, if you're younger, it could indicate dangerously high cholesterol levels.
