Definition of Keratitis
Keratitis means inflammation of the cornea, the clear front part of the eye. It can happen for many reasons like infections, injuries, or other health issues. Spotting the signs early is key to treating it well.
Prevalence and Incidence
Keratitis is a big health issue in the U.S. and around the world. It’s more common in some places because of poor eye care access. Studies show thousands of cases each year, showing we need more awareness and quick medical help to keep eyes healthy.
Learning more about keratitis helps doctors and everyone else to fight it better. This can help protect eyes worldwide.
Common Causes of Keratitis
Keratitis is an inflammation of the cornea. It can come from many things like germs and the environment. Knowing what causes it helps in preventing and treating it. We will look at the main causes, like bacteria, viruses, fungi, and parasites.
Bacterial Infections
Bacterial keratitis is often from germs like *Staphylococcus aureus* and *Pseudomonas aeruginosa*. People who wear contact lenses are at risk. This is because not cleaning lenses right can let bad germs get into the eye. If not treated, it can cause a lot of pain, ulcers on the cornea, and even blindness.
Viral Infections
Viral keratitis is usually from the herpes simplex virus (HSV) and varicella-zoster virus (VZV). It can come back and cause inflammation in the cornea. It needs to be managed for a long time. Signs include red eyes, a lot of tears, and blurry vision. Treatment often involves antiviral drugs.
Fungal Infections
Fungal keratitis is not as common but can happen from fungi like *Fusarium*, *Aspergillus*, and *Candida*. It’s often seen in people who work outdoors or get hurt by plants. The signs can be slow to show, making it hard to catch early. It needs special medicine to treat.
Parasites and Other Causes
Parasitic keratitis is a big problem, especially from *Acanthamoeba* species. It’s a big risk for people who wear contact lenses and don’t keep them clean. Other things like dry eyes, using contact lens solution for too long, and small eye injuries can also make someone more likely to get keratitis.
| Cause | Pathogen/Source | Common Symptoms | Risk Factors |
|---|---|---|---|
| Bacterial Infections | *Staphylococcus aureus*, *Pseudomonas aeruginosa* | Severe pain, corneal ulcers | Contact lens misuse, poor hygiene |
| Viral Infections | Herpes simplex virus, Varicella-zoster virus | Redness, tearing, blurred vision | Previous eye infections, compromised immunity |
| Fungal Infections | *Fusarium*, *Aspergillus*, *Candida* | Gradual discomfort, light sensitivity | Exposure to organic matter, corneal injury |
| Parasitic Infections | *Acanthamoeba* species | Severe pain, visual impairment | Improper lens sanitation, water exposure |
Symptoms of Keratitis
Keratitis can show in many ways, like changes in how you see and what you feel. Knowing these signs is key to catching it early and treating it right.
Visual Indicators
Look out for these signs in your vision:
- Blurred vision, which often suggests a severe progression of the eye disorder.
- Increased sensitivity to light, also known as photophobia.
- Noticeable redness in the eye that persists beyond typical irritation.
Physical Sensations
You might also feel certain things. Important feelings to watch for are:
- Persistent eye pain, ranging from mild discomfort to severe pain.
- Excessive tearing or discharge from the eye.
- A feeling of a foreign body in the eye which does not subside with blinking or washing.
When to Seek Medical Attention
Knowing when to get help is crucial to protect your vision. See an eye doctor if you have keratitis symptoms that don’t go away or get worse. Early treatment can help avoid serious problems.
Diagnosis and Testing
Getting the right diagnosis is key to treating keratitis. Doctors use many ways to make sure they get it right. This keeps eyes healthy.
Clinical Examination
The first step is a detailed clinical examination. Doctors look closely at the eye with special tools. They use slit lamps to see the cornea clearly.
This helps spot signs of keratitis like inflammation or ulcers. It also helps tell it apart from other eye problems.
Laboratory Tests
Keratitis of the Eye Causes & Care After the exam, tests in the lab help find out why keratitis happened. They look at corneal scrapings for bacteria, viruses, fungi, or parasites. Knowing the cause helps pick the right treatment.
Imaging Techniques
Some cases need special pictures of the cornea. Tools like corneal topography and confocal microscopy make these pictures. They show details that can’t be seen with just the eye.
These pictures help doctors understand keratitis better. This leads to better care for the condition.
| Diagnostic Tool | Purpose | Benefits |
|---|---|---|
| Clinical Examination | Initial assessment of the cornea | Identifies signs of inflammation and ulceration |
| Laboratory Tests | Analyze corneal scrapings | Determines the causative pathogen |
| Imaging Techniques | Detailed corneal analysis | Provides thorough structural insights |
Types of Keratitis
Keratitis is when the cornea gets inflamed. It has two main types: infectious and non-infectious. Knowing the difference helps doctors treat it right.
Infectious keratitis comes from germs like bacteria, viruses, and fungi. These germs can cause big problems if not treated fast. Here are some examples: Keratitis of the Eye Causes & Care
- Bacterial Keratitis: This happens often with bad contact lens use and can get worse fast.
- Viral Keratitis: It’s usually from viruses like adenoviruses and herpes simplex, and it can come back.
- Fungal Keratitis: This is more common in people with weak immune systems or those who touch plants that hurt their eyes.
- Acanthamoeba Keratitis: This is from a tiny amoeba and is a big worry for people who wear contact lenses.
Non-infectious keratitis is not from germs. It can be from injuries or other health issues. Here are some types:
- Photokeratitis: This is from too much UV light, often in skiers or people in high places.
- Neurotrophic Keratitis: This happens when nerves don’t work right, making the cornea heal slowly.
- Allergic Keratitis: This is from allergies, maybe from things outside or in the eyes.
- Macular Dystrophy: This is a genetic issue where bad proteins make the cornea cloudy.
| Subtype | Cause | Common Features |
|---|---|---|
| Bacterial Keratitis | Bacteria | Rapid onset, pain, redness |
| Viral Keratitis | Viruses | Tearing, light sensitivity, recurring infections |
| Fungal Keratitis | Fungi | Slow onset, blurred vision, less pain |
| Acanthamoeba Keratitis | Amoebas | Severe pain, ring-shaped infiltrate, associated with contact lenses |
| Photokeratitis | UV Light | Temporary vision loss, pain, gritty sensation |
| Neurotrophic Keratitis | Nerve Damage | Loss of corneal sensation, poor healing, frequent erosions |
| Allergic Keratitis | Allergens | Itching, redness, swelling |
| Macular Dystrophy | Genetic | Gradual vision loss, corneal clouding, painless |
Knowing about keratitis helps us treat it better and prevent it. Spotting the signs and understanding the causes is key to keeping our eyes safe.
