Summary
Accurate localization of retinal tears using 3D reconstruction and computer-aided design simplifies surgical planning for rhegmatogenous retinal detachment (RRD). This method, combined with Foldable Capsular Buckle (FCB) implantation, achieved high success rates and improved vision.
Area of Science:
- Ophthalmology
- Medical Imaging
- Surgical Technology
Background:
- Rhegmatogenous retinal detachment (RRD) requires precise surgical intervention.
- Accurate localization of retinal tears is crucial for successful extraocular buckling procedures.
- Existing methods for tear localization can be time-consuming and may lack precision.
Purpose of the Study:
- To develop and validate a computer-aided method for precise localization of retinal tears.
- To assess the efficacy of this localization technique when combined with Foldable Capsular Buckle (FCB) implantation for RRD treatment.
Main Methods:
- Utilized computer-aided design (CAD) software and 3D reconstruction to model the eye and calculate tear position based on anatomical landmarks.
- Calculated half circumferences and chord lengths to determine tear localization relative to the macula and optic disc.
- Applied the method for preoperative planning and subsequent FCB implantation in RRD patients.
Main Results:
- The computer-aided method provided accurate localization of retinal tears.
- Retinal reattachment was achieved in 97.7% of patients (42/43) following FCB implantation.
- Significant improvement in visual acuity was observed, with a median increase from 0.10 to 0.40 (p < 0.001).
- Postoperative intraocular pressure remained within normal limits, with a mild mean increase of 2.1 mmHg.
Conclusions:
- A simple, ruler-based, computer-aided method allows for accurate preoperative localization of retinal tears.
- This technique facilitates precise FCB fixation point calculation for extraocular buckling.
- The method offers a practical and effective solution for surgeons treating RRD.
