Glaucoma: Overview

1.1K
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...

Persistent subepithelial haze can occur after femtosecond laser-assisted in situ keratomileusis (LASIK) with thin flaps. This complication, localized below Bowman's layer, resolved with steroid treatment, restoring visual acuity.

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Laser Vision Correction

Background:

  • Femtosecond laser-assisted in situ keratomileusis (LASIK) is a common refractive surgery.
  • Thin flap creation is a variation in LASIK procedures.

Observation:

  • Two patients developed persistent subepithelial haze post-LASIK with thin flaps.
  • Haze was observed 3 months after surgery, impacting visual acuity.
  • Haze was located 20-40 microm below Bowman's layer.

Findings:

  • Subepithelial haze formation is a potential complication of thin-flap LASIK.
  • Topical steroid treatment over 12 weeks led to slow resolution of the haze.
  • Uncorrected visual acuity returned to 20/20 at 6 months post-treatment.

Implications:

  • This finding highlights a novel complication associated with thin-flap LASIK.
  • Early detection and steroid treatment may be crucial for managing this complication.
  • Further research is needed to understand the pathogenesis and long-term outcomes.
