研究目的
To assess the effects of surgeon-related factors on laser peripheral iridotomy (LPI) outcomes by comparing residents and glaucoma specialists, and to look for demographic and clinical predictive factors associated with LPI complications.
研究成果
Increased clinical experience led to significantly better outcomes in LPI procedures. Anticoagulant and antiplatelet agents should not be stopped before LPI.
研究不足
Retrospective design limited the ability to reliably capture iris pigmentation information. Differences in race, glaucoma diagnosis, and baseline VA between groups may affect outcomes.
1：Experimental Design and Method Selection:
Retrospective cohort study comparing LPI outcomes between residents and glaucoma specialists.
2：Sample Selection and Data Sources:
Patients who underwent LPI at the Wills Eye Hospital Glaucoma Clinic between September 1, 2012, and December 31,
3：List of Experimental Equipment and Materials:
20 Nd:YAG laser (Coherent Aura, Lumenis; Yokneam, Israel), Abraham Lens (Ocular Abraham Iridectomy YAG Laser Lens).
4：Experimental Procedures and Operational Workflow:
LPI performed under magnification of an Abraham Lens using the Nd:YAG laser. Anterior chamber characteristics and IOP assessed 45 minutes post-procedure.
5：Data Analysis Methods:
Logistic regression analysis with modification for rare events to examine relationships between dependent variables and the group, adjusted for clinical and demographic characteristics.
