Summary
Scleral patch grafting effectively restores globe integrity in scleral defects, achieving tectonic success in most cases. This procedure offers a viable solution for structural and visual preservation.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Ocular Reconstruction
Background:
- Scleral defects pose significant challenges to globe integrity and visual function.
- Effective management strategies are crucial for preserving ocular structure and vision.
Purpose of the Study:
- To evaluate the visual and structural outcomes of scleral patch grafting for scleral defects.
- To assess the efficacy of scleral patch grafting in restoring ocular integrity.
Main Methods:
- Retrospective interventional case series of 13 patients undergoing scleral patch grafting.
- Utilized alcohol-preserved full-thickness sclera for defect repair, covered with conjunctival flap or amniotic membrane.
- Assessed structural integrity and visual outcomes post-operatively.
Main Results:
- Tectonic success achieved in 76.9% of eyes (10/13).
- Common etiology: necrotizing scleritis post-pterygium surgery (40%).
- Complications included endophthalmitis, graft necrosis, and dehiscence; visual acuity stable in 60%.
Conclusions:
- Scleral patch grafting is an effective and simple method for preserving globe integrity.
- Conjunctival or amniotic membrane coverage enhances graft success.
- The procedure offers both structural and functional benefits for eyes with scleral defects.
