Angle Closure Glaucoma: Treatment

1.0K
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...

Open Angle Glaucoma: Treatment

887
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

Area of Science:

  • Ophthalmology
  • Corneal Surgery
  • Refractive Surgery

Background:

  • Corneal ectasia is a known complication following refractive surgery.
  • Keratoconus is generally considered a contraindication for refractive surgery due to risks of ectasia.
  • Mild or fruste keratoconus presents unique challenges for refractive surgery candidacy.

Purpose of the Study:

  • To evaluate the long-term clinical outcome of advanced surface ablation in a patient with mild keratoconus.
  • To assess the safety and efficacy of surface ablation as an alternative for selected keratoconus cases.
  • To highlight the importance of patient selection and pre-operative evaluation in managing mild keratoconus.

Main Methods:

  • The study involved a case report of a patient with mild (fruste) keratoconus.
  • Advanced surface ablation was performed as the refractive surgery technique.
  • The patient's clinical outcome was followed for 15 years post-operatively.

Main Results:

  • The patient demonstrated a positive clinical outcome 15 years after advanced surface ablation.
  • This suggests that surface ablation can be a safe and effective option for select mild keratoconus cases.
  • Comprehensive pre-operative assessment was fundamental to the successful management of this case.

Conclusions:

  • Advanced surface ablation can be a suitable treatment option for carefully selected patients with mild keratoconus.
  • Thorough pre-operative evaluation of corneal properties and patient education are essential for successful refractive surgery in keratoconus.
  • Long-term follow-up supports the potential for favorable outcomes in these challenging cases.
