Summary
Photorefractive keratectomy (PRK) can lead to corticosteroid-induced glaucoma, a serious complication causing optic nerve damage. Patients require careful screening and risk disclosure before PRK surgery to prevent vision loss.
Area of Science:
- Ophthalmology
- Corneal Surgery
- Glaucoma Research
Background:
- Photorefractive keratectomy (PRK) is a common refractive surgery for myopia.
- Topical corticosteroids are frequently used post-PRK to manage inflammation and prevent corneal haze.
- Elevated intraocular pressure (IOP) is a known side effect of corticosteroid use.
Observation:
- A 41-year-old male patient developed significant corneal haze after PRK.
- Intensive topical corticosteroid treatment resulted in elevated IOP and optic nerve damage.
- The patient's condition necessitated a glaucoma filtering procedure due to inadequate response to medical management.
Findings:
- Corticosteroid-induced glaucoma is a potential complication following PRK.
- Aggressive corticosteroid regimens increase the risk of secondary glaucoma.
- Glaucoma secondary to corticosteroid use may require surgical intervention.
Implications:
- Ophthalmologists must carefully screen patients for glaucoma risk factors before PRK.
- Informed consent regarding the risk of corticosteroid-induced glaucoma is crucial for PRK candidates.
- Close monitoring of intraocular pressure is essential during and after corticosteroid treatment post-PRK.
