Your eyes are one of the most important parts of your body. They are delicate and essential. But, there are instances of it getting injured. Corneal abrasion or scratched eye is one of the most common injuries related to the eye. It causes discomfort to the eyes. It also leads to reddening of the eye and makes it hypersensitive to light. Corneal abrasions are caused due to loss of corneal cell in the upper region of the cornea. The top or upper layer is known as corneal epithelium.
Cornea is the front part of the eye. It’s task is to help in focusing of light and enables us to see objects. A good and healthy cornea is needed and a must for having good eyesight. Thus, it is always advisable to visit an ophthalmologist immediately after you notice a corneal abrasion or meet with an accident that has led to corneal injury.
What Are The Factor That Causes Corneal Abrasions?
There are a number of ways that can result in corneal abrasion. It should be kept in mind that anything that comes in direct contact with the eye can lead to corneal injury. It is a painful scratch on the clear part of the eye or cornea.countless ways to get a corneal abrasion. Objects ranging from tree branches, paper, make up tools, finger, pet, debris in the workplace to sports toll, anything can cause an injury to the eye.
Most of the corneal abrasions are n’t caused due to traumatic incidents that are noticeable. Your cornea might get affected by sand, dust and any other tiny object. The chance of corneal abrasion increases with dry eyes. The problem gets worse at the time of waking up from sleep. If your eyes are dry, it will get hurt as the lids can tear and dislodge a part of the cornea. It is a myth that contact lenses protect your eyes. They can also be the cause behind corneal abrasion.
Symptoms Of Scratched Cornea:
It is important to know that the cornea is one of the most sensitive parts of our body. Any injury in the cornea can be really painful. Other symptoms may include redness, tearing, headache, blurry vision, etc.
Treatments For Corneal Abrasion:
The treatment depends upon the severity of the injury. Minor injuries can be cured with the help of non-preserved lubricating drops. It fastens the natural healing process. These are also treated with the use of antibiotic drops. The healing may take some two to three days times.
Treatment for a corneal abrasion depends on the severity of the wound and the cause. Minor abrasions sometimes can be treated with non-preserved lubricating drops to keep your eye moist and comfortable while your eye's natural healing process takes place. In critical cases, an antibiotic ointment might be asked to use for a longer period.
Sight is one of our most important senses. To ensure that your vision is not compromised, regular eye examinations are essential. This is regardless of age and overall health because the only way to diagnose conditions in the eye in the early stages is with a comprehensive eye exam. By arresting them in the early stages, many eye disorders can be easily controlled and treated.
During a routine eye examination, the doctor will look into a number of aspects of your eye's health. An eye examination can also indicate serious health issues like diabetes, macular degeneration and glaucoma. Every person above the age of 40 should go for routine checkups to nullify the chances of issues like glaucoma, presbyopia, difficult near vision, etc. These checkups are really mandatory for people who feel sleepy after some work or have a headache while reading.
If you already have a prescription this will be checked. In other cases, the strength of the eye muscles is checked for nearsightedness, farsightedness and astigmatism which can be corrected with Lasik surgery, spectacles or lenses. The earlier a refractive error is corrected, the lower are its chances of increasing. When it comes to children, they often do not realize signs of vision deterioration and hence, an eye examination becomes essential.
This is a condition where one eye has a much higher refractive error than the other or where the eyes are misaligned. If this is not treated in time, amblyopia can stunt vision in the affected eye and result in blindness.
Crossed or turned eyes are termed as cases of strabismus. This is caused by the misalignment of the eyes and can cause problems with depth perception. This can lead to amblyopia and eventual blindness if not treated in time.
Focusing and communicative problems between the eyes
An eye examination can also determine problems with focusing on objects. With children, this can be a sign of underdeveloped focusing skills while in adults it can be a symptom of presbyopia or age-related diminished focusing ability. Your doctor will also check how well your eyes work together. If they do not work in tandem, it can cause headaches, eye strains and problems with reading.
By looking at the blood vessels and retina of the eyes, doctors can detect signs of high blood pressure, cholesterol etc. Leaks in the blood vessels or bleeding in the eyes can also be a sign of diabetes or swelling of the macula.
As with the rest of the body, the eye tissues and muscles also degenerate with time. Cataract is one of the most common age-related issues that affect the eyes.
Color vision problem:
Detecting this problem is very necesssary, esspecially in case of children. Every student must go for regular eye checkups to avoid such problems and eventually opt for the desired professsional career.
Macular Degeneration is an age-related macular degeneration incurable eye disease, which might result in blurred vision or no vision in the centre of the vision field, which might lead to visual distortions, reduced central vision, decreased intensity of the colours and can make it difficult for the patient to recognize faces, read, drive and to perform other activities.
Types of Macular Degeneration:
1. Dry Macular Degeneration: It is characterized by the presence of drusen and thinning of macula because of a breakdown or thinning of the layer of retinal pigment epithelial cells in the macula.
2. Wet macular degeneration: In this type of AMD, there is an excessive growth of blood vessels, which causes bleeding, leakage, as well as scaring under the retina, which results in a rapid and severe loss of the central vision and might become permanent if not treated.
Causes of Age-related Macular Degeneration:
This is caused due to a problem related to the part of eye known as Macula, which is a spot at the centre of the retina of the eye. The focus point of the incoming ray of light is on Macula, which is responsible for see the things direct in front of us, especially reading and writing.
- Age: As the age increases, the probability of developing Age-related Macular Degeneration also increases significantly. The degree of the macular degeneration might vary person to person, but ageing is a major cause of suffering from age-related macular degeneration.
- Smoking: Smoking increases the chances of developing the disease in comparison to someone who does not smoke. The longer you have smoked, the more are the chances of developing it.
- Family History: The risk of developing the Age-related Macular Degeneration increases if it runs in your family, i.e. if your parents and siblings are suffering from it, then your chances of developing it are quite high as compared to the ones who do not have any family history.
- Obesity: The obese people have the higher chances of developing Age-related Macular Degeneration.
- Alcohol: Higher alcohol consumption also puts you at the risk of AMD, which is why one should always take alcohol in limited quantity only.
- Sunlight: As going out in sunlight without sunscreen is harmful to your skin, the same is harmful to your eyes for longer duration, and one should always wear UV-absorbing sunglasses to protect his eyes from AMD.
- Ethnicity: The white and Chinese are more prone to developing AMD as compared to the black people.
- Cardiovascular disease: The persons who have suffered diseases that affect the heart and other blood vessel are at higher risk of macular degeneration.
Treatment of Age-related Macular Degeneration
1. Anti-VEGF Drugs: The dry macular degeneration cannot be cured while the wet macular degeneration can be stabilized and maintained with a number of medical treatments to be injected into the eye, such as Lucentis, Avastin and Eylea. These are not long procedures and continued monitoring of the vision to maintain or improve the vision.
2. Laser photocoagulation: It consists of a concentrated beam of high energy thermal light that is directed towards the retina to obliterate and seal leaking blood vessels. If you wish to discuss about any specific problem, you can consult an ophthalmologist.
Hii, I am 20 years old and my eye sight is low i.e. -1.25 on both eyes. I want to know whether lasik eye surgery is good option or not as I am irritated of wearing glasses. Also tell me its uses and side effects.
Mere 40 din ki beti hai us ki ek eyes mein yellow kuch bnaty hai Dr. nay tuberyclim solutions ups deya but us ko use krna say eye red ho rhi hai.
Maine 2012 me lasik operation krwaya tha. Ab kuch time se mjhe left eye se kam dikhai de rha h kya main fir se specs use kr skti hu.
Amblyopia is commonly known as 'LAZY EYE'. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to 'see' and develop binocularity, that is the ability to perceive depth (Stereoacuity). This occurs in the first 8 to 10 years of life. Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions ( adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to 'see' and becomes 'lazy'. This condition is seen in 1-4% of population.
The common causes for dissimilar images or Amblyopia are :
1. Misalignment of the eyes or squint - It is the primary reason for Amblyopia is misalignment of the eyes. In case both your eyes are not aimed in the same direction, the image captured by each eye is different , resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.
2. Refractive Amblyopia -
a. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5D of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
b. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.
3. Cloudiness in visual system or visual deprivation Amblyopia - Any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to Amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood( drooping of one eyelid, eyelid swelling, patching of one eye).
Treatment for Amblyopia
For treatment of Amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.
Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye 'learns to see'. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.
To be effective, treatment should be implement as early as possible , within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.
