Summary
Retinoblastoma survivors often experience long-term visual field defects. Tumor characteristics and treatment methods significantly influence the type and extent of these vision impairments.
Area of Science:
- Ophthalmology
- Oncology
- Medical Imaging
Background:
- Retinoblastoma is a primary intraocular malignancy in children.
- Treatment for retinoblastoma can lead to long-term ocular complications.
Purpose of the Study:
- To characterize visual field defects in retinoblastoma survivors.
- To correlate visual field defects with tumor characteristics and treatment modalities.
Main Methods:
- Study included 31 patients treated for retinoblastoma.
- Humphrey visual field testing was performed on 33 eyes.
Main Results:
- 27 patients (29 eyes, 68 tumors) were analyzed.
- 26 of 27 patients exhibited absolute and relative visual field defects.
- Four types of defects were identified and correlated with tumor location and therapy.
Conclusions:
- Retinoblastoma survivors present with diverse long-term visual field defects.
- Tumor size, location, and treatment modality are key determinants of defect severity and type.
