Optimizing Filtration Surgery Procedures in African-Derived Populations: Trabeculectomy and Preserflo.

BACKGROUND

African-derived populations are disproportionately affected by primary open-angle glaucoma (POAG) and face increased risks of surgical failure due to anatomical and genetic factors. This report identifies challenges in glaucoma care and strategies to optimize surgical outcomes in patients from African-derived backgrounds.

METHODS

Six UK-based consultant ophthalmic glaucoma surgeons with extensive experience in diverse patient populations convened to discuss challenges and key approaches for optimising glaucoma filtration surgery outcomes in African-derived populations. Their opinions were supplemented by published literature to propose tailored recommendations and address some of the known challenges in this important patient group.

RESULTS

Surgical treatment of glaucoma among African-derived populations includes challenges such as Tenon's thickness, variable wound healing, and an increased risk of scarring. Preoperatively, outcomes can be improved through patient education, counselling and ocular surface optimisation, including reduction of preservative exposure. Intraoperatively, surgeons may consider the use of general anaesthesia or conscious sedation in younger patients, higher or prolonged mitomycin C exposure tailored to individual risk, and separate closure of Tenon's capsule and conjunctiva to reduce bleb failure. Proactive postoperative care should include intensified steroid regimens and 5-fluorouracil use when indicated.

CONCLUSION

These insights support the delivery of culturally informed, evidence-based glaucoma care tailored to patients from African-derived backgrounds. By adopting a personalised and proactive approach, healthcare professionals may achieve more consistent and favourable surgical outcomes in this high-risk group.
