FUNGAL CORNEAL ULCER

 Fungal Corneal Ulcer:

Introduction: A Fungal Corneal Ulcer is a type of infection caused by various types of fungi that affects the cornea of the eye. The cornea is the clear outer layer of the eye that helps to focus light and protect the inner structures of the eye. When this protective layer becomes infected, it can cause a significant amount of pain and lead to serious visual impairment if left untreated.

Causes: Fungal corneal ulcers are typically caused by a fungal infection of the cornea. The most common fungal organisms that cause these infections are Aspergillus, Fusarium, and Candida species. The infection can occur due to the exposure to contaminated water or soil, using contaminated contact lenses, or even a pre-existing eye condition such as keratitis.

Risk Factors: Some of the risk factors that can increase the chance of developing a fungal corneal ulcer include:

  • Exposure to contaminated water or soil
  • Use of contaminated contact lenses
  • Pre-existing eye conditions such as keratitis
  • Trauma to the eye
  • Use of topical corticosteroids
  • Suppressed immune system
  • Individuals who have chronic conditions such as diabetes, rheumatoid arthritis, and HIV/AIDS are at increased risk.

Symptoms: The symptoms of a fungal corneal ulcer can vary depending on the severity of the infection. Common symptoms include:

  • Pain in the affected eye
  • Redness and swelling of the eye
  • Blurred vision
  • Photophobia (sensitivity to light)
  • Presence of white blood cells (leukocytes) in the anterior chamber, which can be seen as a layering of cells at the bottom of the chamber
  • Corneal ulceration
  • Itchy and swollen eyelids
  • Discharge from the eye

Diagnosis: Fungal corneal ulcer is diagnosed through a combination of clinical examination and laboratory tests. An ophthalmologist will typically perform a thorough eye examination, including a slit-lamp examination to look for signs of inflammation and infection in the cornea. Additionally, a sample of the infected tissue may be taken for culture or PCR test to identify the specific fungus causing the infection.

Treatment: Treatment for a fungal corneal ulcer typically involves the use of antifungal medication, both topical and systemic. Topical antifungal drops or ointments are used to directly target the infection in the cornea. Systemic antifungals, such as oral or intravenous drugs, are used to target the fungus throughout the body. In some cases, surgical intervention may also be necessary to remove infected tissue or repair damage caused by the infection.

Prevention: Fungal corneal ulcers can be prevented by taking steps to reduce the risk of fungal infection. These include:

  • Properly cleaning and storing contact lenses
  • Avoiding exposure to contaminated water or soil
  • Promptly treating pre-existing eye conditions
  • Practicing good hygiene to prevent the spread of infection
  • Using appropriate personal protective equipment when working in environments where there is a risk of fungal exposure.

Conclusion: Fungal corneal ulcer is a serious infection of the cornea caused by fungal organisms. It can lead to significant visual impairment if left untreated. Risk factors include exposure to contaminated water or soil, use of contaminated contact lenses, pre-existing eye conditions and a suppressed immune system. Early diagnosis and treatment with antifungal medication, as well as surgical intervention

ABETALIPOPROTEINEMIA (BASSEN-KORNZWEIG SYNDROME) Retinopathy

Image
Abetalipoproteinemia, also known as Bassen-Kornzweig syndrome, is a rare genetic disorder that affects the body's ability to absorb and transport fats and fat-soluble vitamins. One of the ways that abetalipoproteinemia can affect the eyes is by causing retinitis pigmentosa, a condition that causes vision loss. Retinitis pigmentosa is a degenerative eye disease that affects the retina (the light-sensitive layer at the back of the eye). It is characterized by the gradual loss of photoreceptor cells (cells that detect light and send signals to the brain) and the accumulation of pigment in the retina. This can cause vision loss and may lead to blindness in severe cases. Abetalipoproteinemia can also cause optic atrophy, a condition in which the optic nerve (the nerve that carries visual information from the eye to the brain) becomes thin and weak. This can cause vision loss and other visual problems. In conclusion, abetalipoproteinemia can affect the eyes by causing reti...

What is myopia?

Image
Myopia is nearsightedness and this condition of eye occurs when the power of eye is increased from the normal powers of eye. The normal powers of eye is 58DS and the eye with >58DS eye power will be marked as myopic eye.  Definition   When parallel light rays coming from the infinity focus Infront of the retina while the accommodation should be at rest this condition of eye is known as myopia.

Scleritis

Scleritis 👌is a painful inflammation (swelling) the sclera. The tough, fibrous tissues of the sclera form a protective outer layer for the eye and make up 83 percent of the eye’s surface. In almost half of all cases, scleritis is associated with an underlying autoimmune disorder such as rheumatoid arthritis. There are two main types of scleritis: anterior and posterior. Anterior scleritis, the most common type, affects the front portion of the sclera. There are three types of anterior scleritis: Diffuse scleritis is the most common type and fortunately the most treatable. This type displays widespread redness and inflammation throughout the whole or a portion of the front portion of the sclera.     Nodular scleritis, is characterized by the presence of nodules , often tender to the touch, on the surface of the eye.     Necrotizing scleritis is the most severe form of anterior scleritis. It has the ability to destroy scleral tissues an...
