It causes thinning and eventually bulging out of the cornea in a cone-shaped structure.
This change in its curvature or shape causes<\/a> blurred vision and other eyesight-related problems, such as Astigmatism.
KC is a non-inflammatory, progressive, bilateral, and primary<\/a> Ectatic Corneal Disease (ECD).
ECD is a group of progressive eye conditions that affects the cornea and can result in mild to severe vision impairment.<\/p>\n\n\n
Keratoconus stages<\/h2>\n\n\n
There are four stages of Keratoconus. The condition gets progressively dangerous and may<\/a> lead to distorted and unclear vision. Early Keratoconus condition has less distortion with no progression. In this stage, corneal distortion increases, and vision quality changes. The corneal condition changes from slightly distorted to moderately distorted. In this stage, the cornea faces extreme distortion, scarring, and thinning in its structure. In the early stages of KC, people may not<\/a> notice any symptoms.\u00a0 The scarring of the cornea loses its smoothness and becomes unclear. Sensibilit\u00e0 alla luce<\/a> is another symptom that affects your daily life. The cornea’s thinning and protrusion (bulging out) cause corneal distortion and result in irregular Astigmatism. KC also shows signs of Myopia. Initially, Fleischer rings do not<\/a> cause any symptoms. However, as KC progresses, it can be seen with the naked eye. People may notice red eyes as an<\/a> early sign of KC. Acute Corneal Hydrops is also associated with Keratoconus. The definitive causes of<\/a> this eye condition are unknown. The risk factors of KC comprise<\/a> environmental and genetic factors. These are the following environmental risks that may elevate the risks of Keratoconus in people:<\/p>\n\n\n UV rays are the<\/a> active source of Reactive Oxygen Species (ROS), and exposure may cause oxidative stress in the KC cornea. Many researchers associate a higher risk of KC in patients who rub<\/a> their eyes. Atopy is a hypersensitivity reaction that includes allergies and Asthma. Compared to cold countries, Keratoconus is prevalent in countries with hot and sunny climates. Having a family history of Kerataconus may elevate the risks of the condition in you. A doctor may diagnose Keratoconus by following the<\/a> techniques mentioned below:<\/p>\n\n\n Examining the patient at a slit-lamp can help diagnose several Keratoconus features. It provides the necessary information about the cornea and its curvature. Keratoconus is a chronic eye disorder, and currently, there is no permanent cure for the condition. The effective self-care measures to treat Keratoconus are:<\/p>\n\n\n Exposure to unprotected UV rays (sunlight) may worsen your eye condition. Constant rubbing of your eyes can damage the cornea and is a comune<\/a> way of developing KC. Artificial tears may relieve irritation in your dry eyes<\/a>. Allergies may cause eye inflammation, and you can<\/a> accidentally rub them. Antioxidant rich diet is effective in reducing oxidative stress caused due to<\/a> free radicals in the body. The devices that may be helpful in treating Keratoconus are:<\/p>\n\n\n In the early stages of KC, doctors raccomandare<\/a> corrective lenses and spectacles. These are favored when your KC has progressed and caused high Astigmations. It makes your vision blurry and prevents wearing contacts. Surgeries are an effective treatment for people in the advanced stage of Keratoconus. The following surgeries to treat KC:<\/p>\n\n\n The ophthalmologists recommend a cornea transplant depending on the severity of your eye condition.
The stages are:<\/p>\n\n\nEarly stage<\/h3>\n\n\n
It may negligibly or not affect the quality of the image.
You can use spectacles or soft contact lenses for treating early stages, as they may give adequate vision.<\/p>\n\n\nModerate stage<\/h3>\n\n\n
It can be treated with rigid gas-permeable contact lenses covering and neutralizing distortion.
The gas permeability allows gases, i.e., oxygen, to pass through the lens material.<\/p>\n\n\nAdvanced stage<\/h3>\n\n\n
You can use scleral rigid gas permeable contact lenses to improve comfort and stability.
So though these contact len cover the entire cornea, plenty of oxygen reaches the front of the eye, ensuring healthy and comfortable eyes.<\/p>\n\n\nSevere stage<\/h3>\n\n\n
This condition is often marked by poor vision due to reduced contact lens tolerance and difficulty in fitting the lens.<\/p>\n\n\nEarly symptoms of Keratoconus<\/h2>\n\n\n
However, the symptoms may appear in the later stages of the condition.
People may start seeing their KC symptoms in the<\/a> late teen years.
These symptoms gradually progress until 10 to 20 years and may worsen the vision.
Generally, the early signs of the condition may<\/a> appear in one eye. But in most cases, it affects both eyes.
Consequently, people may have two different visions between two eyes.
Therefore, symptoms in one eye may differ<\/a> from the other eye and can change over time.
Alcuni dei symptoms of Keratoconus<\/a> include:<\/p>\n\n\nDistorted vision<\/h3>\n\n\n
![\"distorted](\"https:\/\/WowRxPharmacy.com\/wp-content\/uploads\/2023\/08\/keratoconus-incontent1-1024x536.webp\")
Esso results in<\/a> distorted and blurred vision.
A distorted image occurs when objects or straight lines look wavy or bent incorrectly.<\/p>\n\n\nIncreased sensitivity to light<\/h3>\n\n\n
Long exposure to computer screens may increase<\/a> light sensitivity in people.
People may find it difficult to<\/a> drive at night because of the distortion in vision.<\/p>\n\n\nAstigmatism<\/h3>\n\n\n
Astigmatism occurs when the<\/a> curvature of the cornea or lens is irregular.
It results in periodic bending of light on the cornea causing blurry image formation.
In Keratoconus, the conical cornea bulges outwards.
Hence, people with KC also have Astigmatism symptoms.
However, it is important to note that people with KC have Astigmatism, but not all<\/a> Astigmatism in people lead to KC.<\/p>\n\n\nMyopia<\/h3>\n\n\n
Myopia is an eye defect where people have nearsightedness, and they have difficulty seeing far objects.
Therefore, children with KC may struggle to see whiteboards and screen projections in the classroom.
According to ScienceDirect, as this eye condition increases, it results in more<\/a> irregularity in patients having Myopia and Astigmatism.<\/p>\n\n\nFleischer iron rings<\/h3>\n\n\n
Fleischer rings are formed due to the deposition of rust-colored iron.
These are partial or complete rings in the<\/a> deep epithelium encircling the cone of KC.<\/p>\n\n\nRed eyes and irritation<\/h3>\n\n\n
They may also feel sudden eye irritation and the urge to<\/a> rub them.<\/p>\n\n\nAcute Corneal Hydrops (ACH)<\/h3>\n\n\n
ACH occurs due to<\/a> aqueous (fluid in the eyes) leakage by tearing an eye membrane.
It causes sudden blurry vision and pain in the eyes.<\/p>\n\n\nCauses of Keratoconus<\/h2>\n\n\n
However, many believe that it is caused due to hereditary reasons or it may be caused due to loss of Collagen in the cornea.
Moreover, according to Hopkins Medicines, consistent inflammation due to<\/a> allergies or irritants may elevate the risks of developing KC due to corneal damage. <\/p>\n\n\nRisk factors of Keratoconus<\/h2>\n\n\n
Moreover, according to NCBI, environmental factors might be essential in triggering the condition in genetically predisposed individuals.<\/p>\n\n\nEnvironmental factors<\/h3>\n\n\n
UV lights<\/h4>\n\n\n
It also reduces the enzymes necessary to remove Reactive Oxygen Species and worsens the condition.
Therefore, KC’s prevalence is higher in hot countries than in cold countries.<\/p>\n\n\nRubbing eyes<\/h4>\n\n\n
![\"higher](\"https:\/\/WowRxPharmacy.com\/wp-content\/uploads\/2023\/08\/keratoconus-incontent2-1024x536.webp\")
The usual length of rubbing eyes in KC patients is much higher than in allergic patients.
However, it is still a topic of discussion, as there are many cases of KC in patients having no history of eye rubbing.
Also, researchers believe there can be a mechanical reason behind this, such as poorly fitted rigid contact lenses.<\/p>\n\n\nAtopy<\/h4>\n\n\n
There are conflicting reports between KC and Atopy. However, some researchers believe in this association.
Allergy caused due to animal fur, pollens, and dust particles may be associated with the onset of KC.<\/p>\n\n\nGeographical factors<\/h3>\n\n\n
This geographical disparity is caused due to exposure of UV sunlight in the regions.<\/p>\n\n\nGenetic factors<\/h3>\n\n\n
Family history is present in<\/a> 10-20% of Keratoconus patients.
However, whether familial genetics causes KC is still under research. But many researchers believe in this relation.
Moreover, patients with other conditions, such as<\/a> Down\u2019s Syndrome, are at a higher risk of developing KC.<\/p>\n\n\nDiagnosis of Keratoconus<\/h2>\n\n\n
Slit-lamp examination<\/h3>\n\n\n
In KC, the cornea thins at the central and paracentral parts, and rings form at the base of the cornea.
The examination can clearly show the iron-deposited Fleicher rings and confirm Keratoconus in the person.<\/p>\n\n\nCorneal topography and tomography<\/h3>\n\n\n
The corneal topographic map will show the signs of irregular Astigmatism.
It can also detect and show additional anterior and posterior corneal curvature.
Usually, KC exhibits periodic changes and thinning in its curvature.
The topography map can clearly show the difference in corneal thickness and hence detects the condition before other<\/a> clinical or biomicroscopic signs can be identified.<\/p>\n\n\nTreatments for Keratoconus<\/h2>\n\n\n
However, crucial research is taking place to find a permanent solution to KC.
Fortunately, The Eye Defect Research Foundation has successfully<\/a> identified the genes behind the condition.
They hope to provide effective treatment through gene therapy and stem cell therapy.
However, there are effective treatment methods to improve vision with eye management and vision technology.
Some effective techniques to treat Keratoconus<\/a> are:<\/p>\n\n\nSelf-care treatment without surgery<\/h3>\n\n\n
Wear 100% ultraviolet protection sunglasses<\/h4>\n\n\n
![\"Wear](\"https:\/\/WowRxPharmacy.com\/wp-content\/uploads\/2023\/08\/keratoconus-incontent3-1024x536.webp\")
It is advised to wear 100% UV-blocking sunglasses to prevent<\/a> harmful rays from affecting your eyes.
You can consult your doctor to prescribe sunglasses if you wear corrective glasses.<\/p>\n\n\nAvoid rubbing your eyes<\/h4>\n\n\n
Thus, it is recommended to avoid<\/a> rubbing your eyes as chronic eye rubbing may accidentally damage corneal tissue.
You can wash your eyes to relieve any irritation in the eyes.<\/p>\n\n\nMoisten your dry eyes with artificial tears<\/h4>\n\n\n
You can consult your doctor to prescribe them, as consistent dry eyes may worsen KC.
According to a 2015 study, Cyclosporin A may reduce the<\/a> progression of the disease.
Therefore, it can be a novel treatment for KC. However, it needs more research.<\/p>\n\n\nAnti-histamines to avoid allergies<\/h4>\n\n\n
To avoid this, you can use anti-histamine medications and prevent<\/a> allergens such as pollens.
On facing serious inflammation, you can consult your doctor to avoid complications.<\/p>\n\n\nInclude an antioxidant-rich diet to protect the cornea<\/h4>\n\n\n
It inhibits the disturbances in the body\u2019s metabolism and ensures proper functioning.
Otherwise, it may lead to the worst scenario for KC.
Therefore, you should eat plenty of antioxidants, such as leafy vegetables, soy, beans, etc. <\/p>\n\n\nDevices<\/h3>\n\n\n
Corrective and contact lenses<\/h4>\n\n\n
![\"doctors](\"https:\/\/WowRxPharmacy.com\/wp-content\/uploads\/2023\/08\/keratoconus-incontent4-1024x536.webp\")
It may become a long-term treatment if your cornea stabilizes with time.
Soft contact lenses can be<\/a> suitable for mild KC.
However, a gas-permeable (allows gases to pass through them) rigid contact lens is raccomandato<\/a> in advanced stages.<\/p>\n\n\nCorneal implant (intacs)<\/h4>\n\n\n
Intacs are crescent-shaped, tiny plastic implants placed into your cornea.
It can improve vision by flattening the curvature of the cornea.
The FDA approves intacs, and in patients, it can<\/a> reduce nearsightedness and Astigmatism in KC.
It is an effective device and may delay or even avoid the risk of corneal transplantation.<\/p>\n\n\nSurgery <\/h3>\n\n\n
Corneal transplantation<\/h4>\n\n\n
The doctor surgically removes and transplants the diseased part of<\/a> your cornea with the donor\u2019s cornea.
This procedure, or operation, is also known as Keratoplasty.
Overall, it helps restore vision and reduce pain in the case of KC.<\/p>\n\n\n
