Regular eye exams are crucial for children’s development and well-being. Just like routine check-ups with a pediatrician, comprehensive eye examinations by a qualified eye doctor are essential to identify and address any vision issues early on. In Tallahassee, FL, accessing expert eye care for your children is readily available, ensuring their visual health is in the best hands. These specialized exams go beyond simple vision screenings, utilizing a range of techniques to thoroughly assess your child’s eye health and visual acuity.
One of the fundamental aspects of a children’s eye exam is evaluating how well their eyes work together and independently. Pediatric ophthalmologists employ engaging and age-appropriate tests to understand the overall health of your child’s eyes. A key component in determining the need for corrective lenses like glasses or contact lenses is the use of dilating eye drops. These drops, administered by your eye doctor, allow for a detailed examination of the inner eye. Once the pupils are dilated, specialized equipment is used to accurately measure any focusing errors and assess the overall health of the eye.
The effects of dilating eye drops can vary depending on the type used. While some may last for just a couple of hours, others can extend to one or two days, with most children experiencing dilation for several hours. During this time, your child may find it challenging to focus on near objects. Children with lighter-colored irises might experience dilation for a slightly longer duration. Sunglasses are highly recommended to minimize light sensitivity and discomfort during dilation.

Strabismus and Amblyopia: Common Childhood Vision Concerns
Strabismus and amblyopia are two prevalent vision problems in children that require timely attention from an eye doctor. If left untreated, these conditions can lead to permanent vision impairment. It’s important to understand that children do not naturally outgrow strabismus or amblyopia; however, both are treatable, especially with early detection and intervention by an eye care professional in Tallahassee. Early eye exams and appropriate treatment strategies are vital for improving a child’s vision and preventing long-term complications.
Strabismus: Misaligned Eyes
Strabismus, often referred to as crossed eyes or wall eyes, occurs when a child’s eyes are not properly aligned. This misalignment prevents the eyes from working together effectively, hindering the development of normal vision. Untreated strabismus can lead to amblyopia, further compromising visual development.

Amblyopia: Lazy Eye
Amblyopia, commonly known as “lazy eye,” is a condition characterized by poor vision in one or both eyes because the brain favors one eye and ignores signals from the other. This often results in the dominant eye being used predominantly, while the weaker eye does not develop proper visual acuity. If amblyopia is not addressed early in childhood by an eye doctor, it can impede the development of normal, binocular vision.
Factors Affecting Eye Coordination:
When eyes don’t work in sync, the brain struggles to process visual information correctly. Several factors can disrupt eye coordination, including:
- Alignment Problems (Strabismus): One eye may deviate in a different direction than the other, either consistently or intermittently.
- Focusing Problems: Difficulties in focusing can affect one or both eyes, leading to blurry images being transmitted to the brain. These focusing issues encompass:
- Nearsightedness (Myopia): Distant objects appear blurred.
- Farsightedness (Hyperopia): Near objects appear blurred.
- Astigmatism: Both near and distant objects appear blurred due to an irregularly shaped cornea.
Ideally, children should have their first comprehensive eye exam with an eye doctor well before starting school. During the examination, a detailed review of the child’s health history is conducted to identify any underlying medical conditions that might impact vision.
The subsequent steps in a comprehensive eye exam include:
- Visual Acuity Testing: This determines how well the child sees and assesses for any focusing problems.
- Binocular Vision Testing: This evaluates whether the child’s eyes work together effectively and if the brain is successfully merging images from both eyes.
- Eye Movement Testing: This assesses how well the eyes move and track objects, and if they move in a coordinated manner.
- Eye Alignment Testing: This step confirms if the eyes are properly aligned and focusing together on the same point.
A diagnosis of strabismus indicates that the eyes are misaligned. One eye may turn inward (esotropia), outward (exotropia), upward (hypertropia), or downward (hypotropia), while the other eye looks straight ahead. This misalignment results in the brain receiving two disparate images that it cannot fuse into a single, clear picture.
Causes of Strabismus
Strabismus primarily stems from two main causes:
- Focusing Problems: Farsightedness can cause an eye to turn inward as the child attempts to focus.
- Eye Muscle Imbalance: Weakness or dysfunction in the eye muscles can prevent proper eye alignment.
Esotropia (Cross-Eyed): Describing an eye that turns inward.
Exotropia (Wall-Eyed): Describing an eye that turns outward.
Strabismus Treatment Options
Treatment for strabismus aims to correct the underlying issue causing eye misalignment and is managed by an eye doctor. Common treatment approaches include:
- Eyeglasses: Corrective lenses can address focusing problems that contribute to strabismus.
- Eye Muscle Surgery: In some cases, surgery is necessary to realign the eye muscles and correct strabismus.
- Eye Patching: Patching the stronger eye can sometimes be used to strengthen vision in the weaker eye and improve alignment.
The primary goals of strabismus treatment are to:
- Address the root cause of eye turning.
- Achieve proper eye alignment.
- Maximize vision in both eyes.
- Promote effective teamwork between the eyes.
Strabismus in Adults
Adult strabismus often represents persistent childhood strabismus. However, strabismus that develops in adulthood without a prior history requires careful evaluation by an eye doctor to rule out underlying medical or neurological conditions such as diabetes, thyroid disease, myasthenia gravis, brain tumors, or stroke.
Symptoms of Adult Strabismus: If strabismus has been present since childhood, symptoms are usually minimal. However, if it develops later in life, double vision (diplopia) is the most common symptom.
Causes of Double Vision: Misaligned eyes cause each eye to send a separate image to the brain, resulting in double vision.
Adult Strabismus Treatment: Contrary to a common misconception, adult strabismus is treatable. Adults have various treatment options available, including:
- Prism Glasses: These specialized lenses can help align images and reduce double vision.
- Eye Muscle Surgery: Surgical intervention can realign the eyes.
- Oculinum (Botulinum Toxin) Injections: Injections can temporarily weaken overactive eye muscles to improve alignment.
Adults with strabismus don’t have to live with misaligned eyes. Advances in treatment techniques offer excellent opportunities for improved eye alignment and appearance for most individuals seeking care from an eye doctor.
Amblyopia: Addressing Lazy Eye
Amblyopia, or lazy eye, occurs when the brain prioritizes signals from one eye over the other. Over time, the brain becomes accustomed to relying on only the stronger eye, hindering the development of normal vision in the weaker, ignored eye. Encouraging the brain to utilize both eyes and fostering eye teamwork becomes increasingly challenging as a child grows. Therefore, early intervention by an eye doctor is crucial for effective treatment of amblyopia.
Causes of Amblyopia
The primary causes of amblyopia are:
- Poor vision in one eye: Conditions like refractive errors (nearsightedness, farsightedness, astigmatism) or cataracts in one eye can lead to amblyopia.
- Strabismus: Misaligned eyes can cause the brain to suppress the image from the deviating eye, leading to amblyopia.
Treatment for amblyopia often involves encouraging the brain to use the weaker eye. This is frequently achieved by blocking the stronger eye, forcing the brain to process signals from the weaker eye. With consistent treatment guided by an eye doctor, vision in the amblyopic eye can gradually improve.

Amblyopia Treatment Methods
- Patching: An eye patch is placed over the stronger eye, compelling the brain to rely on and strengthen the weaker eye. The eye doctor will provide specific instructions on patching duration and usage.
- Medicated Eye Drops (Atropine): Atropine eye drops can be used as an alternative to patching. These drops blur vision in the stronger eye, forcing the brain to use the weaker eye.
- Eyeglasses: Glasses can correct focusing problems contributing to amblyopia. They can also be prescribed to blur vision in the stronger eye, similar to eye drops or patching, to encourage weaker eye use. In some cases, a patch or filter may be attached to the eyeglass lens to block vision in the stronger eye. As vision improves, the eyeglass prescription may be adjusted by the eye doctor.
As a child’s vision improves during amblyopia treatment, the treatment plan may be modified by their eye doctor. However, the fundamental goals remain consistent: to optimize vision in each eye and to facilitate effective teamwork between both eyes and the brain. Treatment duration can range from weeks to months. Regular follow-up visits with the eye doctor are essential to monitor treatment progress. Advanced techniques allow for vision testing even in infants and young children. If there’s a family history of misaligned eyes, childhood cataracts, or serious eye diseases, an eye exam by an eye doctor is recommended during infancy.
Eye Injuries: Prevention and Immediate Care
Preventable eye injuries are a significant cause of vision loss. Eye injuries can occur at any age, with nearly half happening during sports and recreational activities. It’s crucial for children to wear appropriate safety glasses or protective eyewear during sports and any activities where the eyes might be struck by foreign objects.
In the event of a chemical eye injury, immediate irrigation with clean water is vital. Flush the affected eye for at least ten minutes using any available clean water source, and seek urgent medical attention from an eye doctor or emergency services immediately. If a sharp object penetrates the eye or there’s suspicion of a small object, like a BB, entering the eye, seek immediate emergency room care. Initially, gently cover the child’s eye and ensure they avoid rubbing it.
Corneal Abrasion: Scratches on the Eye’s Surface
A corneal abrasion is a scratch on the cornea, the eye’s outermost layer. Although thin (0.05 millimeters), this layer is sensitive and can be scratched by relatively minor trauma, resulting in significant pain due to the abundance of sensory nerves in the area.
Corneal abrasions are typically treated by an eye doctor with eye drops, ointments, a patch, or sometimes a specialized contact lens. The ophthalmologist will closely monitor healing to watch for potential infection. Corneal abrasions generally heal quickly, often resolving within one to three days.
In rare cases, a condition called corneal erosion can occur after a corneal abrasion, more commonly in adults. Corneal erosion involves spontaneous abrasions without recent trauma, often due to a faulty connection between the cornea’s outer layer and underlying tissue. Erosions typically occur at night or upon waking and are treatable by an eye doctor.
Conjunctivitis: Pink Eye
Conjunctivitis, or “pink eye,” is an inflammation of the conjunctiva, the clear membrane covering the white part of the eye and inner eyelids. It usually results from a viral infection, causing redness and irritation. Symptoms include eyelid and eyelash crusting, tearing, general eye irritation, and watery or mucoid discharge. Most pediatric conjunctivitis cases are viral, though bacteria, allergies, or chemical exposure (e.g., sunscreen) can also be causes.
Viral Conjunctivitis
Similar to the common cold, there’s no specific medication to cure viral conjunctivitis. An eye doctor may recommend letting the infection run its course, allowing the body’s immune system to fight it off. Antibacterial eye drops are sometimes prescribed to prevent secondary bacterial infections. Due to increasing antibiotic resistance, unnecessary antibiotic use is discouraged, so don’t be alarmed if antibiotic drops aren’t prescribed for viral conjunctivitis. If prescribed, follow directions and complete the full treatment course.
Conjunctivitis, especially the viral type, is highly contagious, easily spread through hand-to-eye contact, sneezing, and coughing. Encouraging children to avoid touching their eyes, mouths, and noses, particularly during cold and flu season, is important.
Most conjunctivitis cases are mild and resolve without complications. However, some bacterial forms can cause vision-threatening issues, especially in newborns. Contact a pediatrician or pediatric ophthalmologist if an infection seems severe.
Newborns may experience eye tearing, often due to a temporary blocked tear duct (nasal lacrimal duct obstruction). However, tearing can also indicate more serious conditions like infantile glaucoma or corneal infections, so consult a physician if your baby has these symptoms.
Styes and Chalazia: Eyelid Bumps
A stye (hordeolum) is an acute infection of eyelid glands at the eyelash base, usually caused by clogged and infected oil glands. Styes appear as red, painful bumps on the eyelid. Large styes can sometimes cause blurred vision.
Styes often resolve on their own. Warm compresses and topical medications from an eye doctor can help speed up resolution.
Chalazia
A chalazion is a chronic eyelid cyst, typically less painful than a stye and representing a chronic issue. Chalazia can arise spontaneously or follow a stye. After a stye’s acute infection resolves, residual oils and inflammatory material can form a chalazion cyst.
Chalazia are usually painless eyelid swellings but can cause blurred vision if they become large, which is common.
Initial treatment involves warm compresses to soften and shrink the chalazion. An eye doctor may also prescribe topical medications. If the chalazion persists, surgical removal in the eye doctor’s office may be necessary.
Cataracts: Clouding of the Eye Lens
Cataracts, clouding of the eye’s internal lens, are often associated with older adults but can also affect children. Congenital cataracts, present at birth, can cause severe and permanent vision loss in children. Dense cataracts obstruct clear retinal images, hindering proper visual information development in the brain. Timely diagnosis and treatment by an eye doctor are crucial, especially for dense congenital cataracts. Cataracts vary in their visual impact.
Causes of Congenital Cataracts
The eye’s lens starts forming around day 21 of pregnancy. Intrauterine abnormalities during or after this period can disrupt proper eye formation. Some cases are inherited, while others result from metabolic problems.
Cataract Treatment
Not all cataracts require treatment. Dense cataracts need urgent intervention, while milder forms may only require monitoring by an eye doctor to prevent amblyopia. If surgery is needed, a small incision is made to remove the cloudy lens. Sometimes, an artificial intraocular lens is implanted. With or without lens replacement, glasses or contact lenses are often prescribed to improve focusing post-surgery, under the guidance of an eye doctor.
