Post penetrating keratoplasty glaucoma - A review

Area of Science:

• Ophthalmology
• Corneal Surgery
• Glaucoma Management

Background:

• Post-penetrating keratoplasty glaucoma presents a significant clinical challenge.
• Its occurrence, difficult diagnosis, and potential for irreversible visual loss necessitate effective management strategies.
• Elevated intraocular pressure post-keratoplasty can jeopardize graft survival and visual outcomes.

Purpose of the Study:

• To review the challenges associated with glaucoma following penetrating keratoplasty.
• To assess pre-operative risk factors, diagnostic methods, and management strategies for post-keratoplasty glaucoma.
• To emphasize the importance of early detection and prompt intervention to preserve vision.

Main Methods:

• This is a review article.
• It synthesizes current knowledge on the incidence, risk factors, diagnosis, and management of glaucoma after corneal transplantation.
• The review discusses the impact of anti-glaucoma medications on corneal grafts and the limitations of current therapeutic options.

Main Results:

• Glaucoma is a frequent and challenging complication of penetrating keratoplasty.
• Pre-operative assessment and intra-operative measures can mitigate the risk of developing glaucoma.
• Prompt medical or surgical intervention is essential to lower intraocular pressure and salvage vision, though glaucomatous optic nerve damage is irreversible.

Conclusions:

• Effective management of post-penetrating keratoplasty glaucoma requires a tailored approach, weighing risks and benefits of treatments.
• While graft exchange is an option, vision loss due to optic nerve damage cannot be restored.
• Early identification and comprehensive management are paramount for preserving vision in patients undergoing corneal transplantation.
