What Is Thin Cornea? Causes, Symptoms, and Eye Care Tips

A thin cornea refers to a condition where the cornea—the clear, dome-shaped front layer of the eye—has a thickness lower than normal, which can affect vision and overall eye health. This condition may result from various causes such as natural aging, frequent eye rubbing, genetic disorders, or side effects from eye surgeries like LASIK. Common symptoms include blurry vision, frequent changes in prescription, distorted images, and unusually high astigmatism.   Understanding the Cornea The cornea is the transparent, curved layer covering the front part of the eye. It helps focus light into the eye for clear vision and serves as a protective barrier against dust and germs. Normally, corneal thickness ranges between 520–550 microns, but it may thin with age.   What Is a Thin Cornea? A thin cornea is typically defined as a corneal thickness of less than 500 microns (0.5 mm). It is not necessarily a disease and often requires no treatment. However, thin corneas can affect certain diagnoses—such as glaucoma—since intraocular pressure readings may appear lower than actual values. Corneal thickness also plays an important role in refractive surgery decisions. For example, patients with thin corneas and high refractive errors (nearsightedness or astigmatism) may not be ideal candidates for LASIK, as the remaining corneal tissue after surgery might be too thin. This could increase the risk of complications like keratoconus or corneal ectasia. In such cases, ophthalmologists may recommend alternative procedures such as PRK, ICL, FemtoLASIK, ReLEx SMILE Pro, or NanoLASIK, which preserve more corneal tissue. Therefore, detailed corneal thickness assessment is essential before undergoing LASIK to ensure safe and effective outcomes.   Does Wearing Contact Lenses Cause Thinning of the Cornea? Generally, wearing contact lenses correctly does not thin the cornea. However, prolonged use without proper cleaning or rest may lead to oxygen deprivation or corneal infections, which can gradually weaken or thin corneal tissue.   Causes of Thin Cornea There are several factors that can lead to corneal thinning: 1. Genetic Conditions Keratoconus: The most common cause, where the cornea gradually thins and bulges outward into a cone shape, leading to irregular astigmatism and blurred vision. It usually appears during the teenage years to early adulthood. Corneal Dystrophies: Such as Pellucid Marginal Degeneration (PMD), where thinning occurs in the lower peripheral cornea. 2. Eye Surgery or Injury Procedures like LASIK or PRK can thin the cornea, especially if excessive corneal tissue is removed. Repeated eye injuries or untreated infections (e.g., corneal ulcers, keratitis) can also cause thinning due to tissue damage. 3. Systemic Diseases and Medication Autoimmune diseases such as Rheumatoid Arthritis or SLE can cause chronic inflammation, leading to corneal thinning.Long-term use of steroid eye drops may also weaken corneal tissue over time.   Symptoms of Thin Cornea Corneal thinning often progresses slowly and may not show early signs. Key symptoms include: Blurry or distorted vision Frequent changes in prescription High or irregular astigmatism Difficulty focusing or double vision   Diagnosis Thin cornea is often detected during pre-LASIK evaluations.Eye doctors use devices like: Keratometer: Measures corneal curvature and astigmatism. Corneal Topography: Creates a detailed map of corneal thickness and shape. Tomographic Biomechanical Index (TBI): Evaluates corneal strength and risk of ectasia. While early symptoms can hint at the condition, only a comprehensive eye exam by an ophthalmologist can confirm it.   Summary Thin cornea is a silent condition that can significantly impact vision if left untreated. Early detection—especially before refractive surgery—is crucial.At Bangkok Eye Hospital, advanced diagnostic tools and experienced specialists ensure accurate corneal thickness evaluation and personalized treatment planning to maintain long-term eye health.     FAQ: Frequently Asked Questions About Thin Cornea 1. Can corneal thickness be increased?No, corneal thickness cannot naturally increase as it is determined by the cornea’s internal structure. 2. What happens if thin cornea is left untreated?It may lead to worsening blurred vision, irregular astigmatism, or even corneal ectasia. In severe cases, acute hydrops or corneal perforation may occur, leading to permanent vision loss if untreated. 3. Can thin cornea be prevented?Yes — by avoiding vigorous eye rubbing, maintaining good eye hygiene, limiting contact lens wear time, and having regular eye checkups, especially if there is a family history of corneal diseases.

Understanding Pterygium: Causes, Symptoms, and Treatment Options

How people notice and see Pterygium without knowing it is Pterygium Have you ever looked in the mirror and noticed a small, fleshy growth on the white part of your eye, usually near the nose? It might appear slightly red, or you might feel like something’s stuck in your eye. This growth can slowly creep onto the clear, center part of your eye, known as the cornea, causing discomfort, dryness, or even blurred vision. Many people mistake these signs for simple irritation, dryness, or tired eyes, unaware that they might be dealing with a condition called pterygium. 1. What is Pterygium? Pterygium (pronounced tuh-RIJ-ee-um) is a common eye condition that looks like a triangular or wedge-shaped growth on the eye’s surface. It usually starts small but can slowly expand toward the cornea. Though it might look concerning, it’s not cancerous. For some, it’s just a minor cosmetic issue, but for others, it can cause vision problems or significant discomfort. Pinguecula and pterygium are often mistaken for each other. Pinguecula is a yellowish bump on the conjunctiva, while pterygium extends onto the cornea and can affect vision. Proper diagnosis is key. 2. Why does it happen? Pterygium happens mainly due to long-term exposure to UV light from the sun, which is why it’s often called "surfer’s eye." But you don’t have to be a surfer to get it - anyone who spends a lot of time outdoors, especially without proper eye protection, is at risk. Dust, wind, and dry environments can also irritate the eye and contribute to its development. Genetics can play a part, too, as pterygium is more common in certain families. 3. What to do when you notice it? If you spot a growth on your eye or feel persistent discomfort, dryness, or redness, don’t ignore it. Make an appointment with an eye specialist, especially if it’s growing or starting to affect your vision. The doctor can diagnose pterygium with a simple eye exam and discuss whether it needs to be treated right away or monitored over time. 4. Treatment Options ✅Observation and Protection: In mild cases, protecting your eyes from the sun with sunglasses and using lubricating eye drops can help keep symptoms in check. ✅Medication: If the pterygium becomes red and inflamed, doctors may prescribe anti-inflammatory eye drops to reduce irritation.  ✅Surgery: When pterygium grows too large, affects vision, or causes significant discomfort, surgery to remove the growth may be recommended. This involves removing the tissue and often placing a graft (a small piece of your own conjunctiva) to cover the area and reduce the chance of it coming back. 5. Advice from Bangkok Eye Hospital and Next Steps At Bangkok Eye Hospital, our experienced ophthalmologists often see patients who are unsure what’s causing their eye discomfort or unusual growths. It’s essential to address these concerns early to avoid complications. If surgery is necessary, one of the best innovations available today is using fibrin glue during pterygium surgery, which offers many benefits over traditional stitches. To learn more about how fibrin glue can improve your recovery and comfort, check out our next article on this advanced treatment here.

Understanding Retinal Diseases: A Focus on Age-Related Macular Degeneration (AMD) and How We Can Help

Welcome to our detailed exploration of retinal diseases, specifically focusing on Age-Related Macular Degeneration (AMD), the main cause of vision impairment among older adults. Here at Bangkok Eye Hospital in Thailand, we are dedicated to providing expert care and comprehensive treatment options to manage and potentially mitigate the impact of AMD on your life. Overview of the Retina and Its Function The retina is a critical component of the eye, essential for vision. This thin layer of tissue, located at the back of the eye, captures light and converts it into electrical signals. These signals are sent to the brain, which interprets them as visual images. The retina's functionality is similar to the film in a camera, capturing the world around us and enabling us to see detailed and colorful images.   Understanding Age-Related Macular Degeneration (AMD) Age-Related Macular Degeneration (AMD) is a prevalent retinal condition that primarily affects individuals over the age of 50. It occurs when the central portion of the retina, known as the macula, deteriorates. The macula is responsible for central vision and visual acuity, which is important for tasks such as reading, driving, and recognizing faces.   Types of AMD AMD manifests in two forms: Dry AMD: This is the more common type and is characterized by the thinning of the macula and the presence of drusen, tiny yellow or white deposits on the retina. Dry AMD progresses slowly and gradually impairs central vision. Wet AMD: Less common but more severe, wet AMD occurs when new, abnormal blood vessels grow under the retina, leading to leakage of fluid and blood. This leakage can cause rapid and severe damage to the macula, leading to significant vision loss. Symptoms of AMD The symptoms of AMD can vary but typically include: §  Blurriness in the central part of the vision §  Distorted vision (straight lines appear wavy) §  Difficulty adapting to low light levels §  Decreased intensity or brightness of colors §  A well-defined blurry spot or blind spot in your field of vision   The Impact of AMD on Vision and Lifestyle AMD significantly affects quality of life by impairing the ability to perform everyday activities that require sharp central vision.   “Early detection through regular eye exams is crucial for managing this disease effectively.”   How Bangkok Eye Hospital Can Help At Bangkok Eye Hospital, our approach to managing AMD involves: ü  Early Detection and Regular Monitoring: Utilizing advanced diagnostic tools, we detect AMD in its earliest stages and monitor its progression. ü  Personalized Treatment Plans: Depending on the type and severity of AMD, treatments may include nutritional supplements, laser therapy, and anti-VEGF injections to slow progression and maintain vision. ü  Low Vision Aids and Support: We provide resources and aids to help patients adapt to changes in their vision, ensuring they can continue to enjoy a high quality of life.

Understanding Glare and its Impact on Vision

Understanding Glare and its Impact on Vision Glare is a characteristic of light that scatters from its source, forming distinct rays or circles. This effect is often observed in relatively dimly lit environments and is less likely to occur in well-lit surroundings. Glare tends to be more pronounced at night and is frequently encountered by individuals with untreated nearsightedness.   For those experiencing glare, it can be particularly bothersome in dark conditions, potentially causing discomfort and a sense of insecurity, especially while driving at night. Therefore, it's advisable to avoid nighttime driving if you're affected by glare. Alternatively, you may consider using anti-glare glasses or applying eye drops to alleviate the condition and improve your night vision.   ** Experiencing glare in well-lit environments and having halos around lights may indicate the onset of cataracts. In such cases, it is essential to promptly consult an ophthalmologist to identify the underlying cause and explore potential treatments. **   Understanding glare and its implications for vision is crucial, as it can significantly impact one's ability to see clearly and safely, particularly in low-light conditions. Seeking professional advice is essential for managing glare-related issues and maintaining optimal eye health.
