Summary
Management of posterior segment intraocular foreign bodies (IOFB) using pars plana vitrectomy (PPV) shows encouraging visual outcomes. Poor initial vision, large IOFB size, and retinal detachment predict worse results.
Area of Science:
- Ophthalmology
- Retina Surgery
- Ocular Trauma
Background:
- Posterior segment intraocular foreign bodies (IOFB) present significant management challenges.
- Pars plana vitrectomy (PPV) and expertise in vitreoretinal surgery are crucial for successful IOFB removal.
- Encircling bands can support the retina by closing anterior breaks and preventing traction.
Purpose of the Study:
- To analyze clinical characteristics of posterior segment IOFB cases.
- To identify predictors of final visual outcome and globe survival after IOFB removal.
Main Methods:
- Retrospective observational study of 40 patients with posterior segment IOFB from January 2016 to June 2019.
- Exclusion of patients with no light perception (NPL) visual acuity.
- Statistical analysis performed using SPSS version 21.
Main Results:
- Mean age was 27.08 years; 95% of patients were male, often farm workers.
- 65% of eyes had Zone I injury; median presentation time was 13.5 days.
- Significant improvement in mean LogMAR visual acuity (2.50 to 1.33, p=0.003); predictors of poor outcome included poor presenting vision, retinal detachment, and large IOFB diameter.
Conclusions:
- Pars plana vitrectomy (PPV) by a vitreoretinal surgeon yields encouraging results for posterior segment IOFB.
- Poor presenting visual acuity, large IOFB diameter, and pre-operative retinal detachment (RD) are significant predictors of poor visual outcome.
