Insights

A case study highlights the risk of methicillin-resistant Staphylococcus aureus (MRSA) ocular infection following UVA-riboflavin corneal cross-linking in a patient with atopic dermatitis, emphasizing careful preoperative assessment and hygiene.

Area of Science:

  • Ophthalmology
  • Infectious Diseases
  • Dermatology

Background:

  • Keratoconus is a progressive corneal condition often managed with corneal collagen cross-linking.
  • Atopic dermatitis is associated with an increased risk of Staphylococcus aureus colonization.
  • Ocular infections, including those caused by MRSA, are potential complications of ophthalmic procedures.

Purpose of the Study:

  • To report a case of methicillin-resistant Staphylococcus aureus (MRSA) ocular infection after UVA-riboflavin corneal collagen cross-linking.
  • To investigate the potential link between atopic dermatitis and postoperative MRSA infection in this context.

Main Methods:

  • A case report detailing a 22-year-old male patient with keratoconus and atopic dermatitis.
  • The patient underwent UVA-riboflavin corneal cross-linking and subsequently developed a severe ocular infection.
  • Microbiological cultures identified MRSA, and treatment involved targeted antibiotic therapy.

Main Results:

  • The patient developed a rapidly progressive corneal abscess and cyclitis five days post-surgery.
  • Cultures confirmed MRSA with significant antibiotic resistance.
  • Despite aggressive treatment, severe ocular damage was unavoidable.

Conclusions:

  • While UVA-riboflavin corneal cross-linking is effective for keratoconus, infectious complications can occur.
  • Atopic dermatitis may be a risk factor for postoperative MRSA infection due to S. aureus colonization.
  • Thorough clinical assessment for comorbidities and strict postoperative hygiene are crucial.

Microbiome of the Eye

The human eye has a specialized microbiota that reflects its unique anatomical and immunological environment. This low-biomass microbial community predominantly colonizes the conjunctiva and eyelid margins, playing a vital role in ocular surface homeostasis and defense. Despite its proximity to the richly colonized facial skin, the ocular surface maintains a distinct microbial profile due to continuous mechanical and biochemical defense mechanisms.The conjunctival surface hosts fewer microbial...

Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...

Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
