Summary
Infectious keratitis can occur years after laser-assisted in situ keratomileusis (LASIK). Lifelong vigilance is crucial for patients and physicians to detect and manage these late-onset infections.
Area of Science:
- Ophthalmology
- Infectious Diseases
Background:
- Laser-assisted in situ keratomileusis (LASIK) is a common refractive surgery.
- Late-onset infectious keratitis following LASIK is a rare but serious complication.
Observation:
- Two cases of infectious keratitis are presented, occurring 6 years and 2 years post-LASIK.
- Case 1 involved a 56-year-old woman with flap interface inflammation and hypopyon.
- Case 2 involved a 23-year-old woman with a corneal infiltrate after trauma.
Findings:
- Cultures identified Pseudomonas mesophilic and Fusarium solani.
- Case 1 resolved with antibiotic therapy, achieving 20/40 vision.
- Case 2 required flap amputation, with visual acuity improving to 20/40.
Implications:
- These cases highlight the risk of microbial keratitis years after LASIK.
- Emphasizes the need for ongoing postoperative monitoring by both patients and ophthalmologists.
- Underscores the importance of prompt diagnosis and appropriate treatment for keratitis following refractive surgery.

01:25Glaucoma: Overview
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
01:22Microbiome 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...
01:28Angle 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...
