ULCUS SERPENS

Ulcus serpens, also known as a serpentine or creeping corneal ulcer, is a type of corneal ulcer that typically presents as a linear or serpentine-shaped area of corneal necrosis that slowly extends and spreads over time. It is typically caused by a bacterial or fungal infection and can lead to severe vision loss if not treated promptly and effectively.

Causes

  • The most common causes of ulcus serpens are bacterial or fungal infections, which can occur as a complication of an existing corneal ulcer or as a result of a penetrating injury to the eye.
  • Other causes include:
    • Herpes simplex virus
    • Tuberculosis
    • Syphilis
    • Pemphigoid

Symptoms

  • Ulcus serpens can present with a variety of symptoms, including:
    • Pain and redness in the affected eye
    • Blurred vision
    • Light sensitivity
    • A white or gray linear or serpentine-shaped area on the cornea

Diagnosis

  • Ulcus serpens is typically diagnosed based on the clinical presentation of the patient, with the characteristic linear or serpentine shape of the ulcer being a key identifying feature.
  • Additional diagnostic tests that may be performed to confirm the diagnosis and identify the underlying cause of the ulcer, including:
    • Culture or PCR test to identify the specific microorganism causing the infection
    • Biopsy of the affected tissue
    • blood tests to identify systemic diseases

Treatment

  • The treatment of ulcus serpens typically involves the use of antibiotics or antifungal medications to eliminate the infection, and surgery to remove the necrotic tissue and repair the damage to the cornea.
  • Topical antibiotics such as ciprofloxacin, ofloxacin, or fortified antibiotics such as vancomycin, ceftazidime, or gentamicin are commonly used to treat bacterial ulcus serpens.
  • Topical antifungal medications such as natamycin (Natacyn) or nystatin, amphotericin B, and fluconazole can be used to treat fungal ulcus serpens.
  • Surgery is typically required to remove necrotic tissue and repair the damage to the cornea.
  • Conjunctival Flap
  • Corneal Scarring and Perforation Prevention: It is important to note that in cases of deep corneal ulcers or severe infection, the infection can lead to corneal scarring and perforation, so it is important to monitor the progress of the healing process, to identify any changes that indicate that the ulcer is not healing properly and to adjust the treatment accordingly.

It is important to note that the treatment plan will depend on the underlying cause of the ulcus serpens, the size and location of the ulcer and the overall health of the eye. In addition to treatment, close follow-up is important to monitor the healing process and prevent any complications.

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...

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...
