Summary
Surgeons
Area of Science:
- Ophthalmology
- Retinal Surgery
Background:
- Epiretinal membrane (ERM) surgery aims to improve vision by removing scar tissue.
- Internal limiting membrane (ILM) peeling is a crucial step in ERM surgery.
- Accurate assessment of the peeled ILM area is important for surgical outcomes.
Purpose of the Study:
- To assess the reliability of surgeons in estimating the internal limiting membrane peeling area (ILMPA) during ERM surgery.
- To evaluate surgeons' ability to achieve a predetermined ILMPA.
Main Methods:
- Surgeons (one senior, two junior) aimed for a target ILMPA (1 optic disc diameter eccentricity) in 30 patients undergoing ERM surgery.
- ILMPA was measured from video recordings, both without dye and after brilliant blue G staining.
Main Results:
- Median ILMPA was 9.3 mm² without dye and 7.4 mm² with brilliant blue G (P=0.17).
- Senior surgeons achieved significantly larger ILMPA than junior surgeons (P=0.01).
- Senior surgeons met the target ILMPA more frequently (87%) compared to junior surgeons (47%, P=0.02).
Conclusions:
- Subjective estimation of ILMPA without dye was moderate.
- Surgical expertise significantly influences the achieved ILMPA in ERM surgery.
