Summary
Corneal hydrops with perforation is a rare complication following laser in situ keratomileusis (LASIK) ectasia. This case highlights the potential for flap dehiscence requiring corneal transplant.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Ocular Pathology
Background:
- Laser in situ keratomileusis (LASIK) is a common refractive surgery. Post-LASIK ectasia is a rare but serious complication.
- Corneal hydrops, characterized by stromal edema, typically occurs in keratoconus. Its occurrence after LASIK is exceptionally rare.
Observation:
- A 41-year-old woman presented with acute visual disturbance, pain, and photophobia in the right eye 10 years post-LASIK.
- Slit-lamp examination revealed a Descemet membrane tear and stromal cleft extending to the LASIK flap interface, with aqueous leakage.
- The contralateral eye showed signs consistent with keratoconus.
Findings:
- Histopathology confirmed a fluid-filled cleft connecting the flap interface, indicative of corneal hydrops with perforation.
- The corneal hydrops and perforation were associated with partial flap dehiscence.
- Penetrating keratoplasty was required due to persistent leakage.
Implications:
- This case underscores the possibility of corneal hydrops and perforation in post-LASIK ectasia.
- Flap dehiscence may be a critical factor in the development of hydrops in these cases.
- Early recognition and surgical intervention, such as penetrating keratoplasty, may be necessary for management.

1.6K
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...

01:25Glaucoma: Overview
1.6K
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...
