To describe the intraoperative use of a modified Spectralis HRA + OCT for obtaining high resolution images in pediatric patients with retinal diseases.
The Spectralis scanning laser ophthalmoscope was disassembled from its table top system and mounted onto a bracket at the end of an adjustable arm. Following anesthesia administration, high resolution images were acquired in the pediatric patients. Throughout the imaging process, eyelids of the children were kept open with a speculum and regular corneal hydration was performed to optimise the quality of the images acquired.
An efficient and consistent technique was established for obtaining intraoperative images with the modified Spectralis HRA + OCT device. A total of 18 pediatric patients (aged 3 months to 16 years) with retinopathy of prematurity, X-linked retinoschisis, optic disc pit related maculopathy, incontinentia pigmenti, coat’s disease, and juvenile chronic arthritis underwent successful imaging with the modified system. Spectral Domain Optical Coherence Tomography (SD-OCT) images were obtained for all the pediatric patients. Additionally, multicolour fundus imaging and fluorescein angiography with the 103 degree ultra-widefield lens was performed in selected pediatric patients. Total imaging time was 5 minutes. No negative side effects were experienced throughout the imaging process. Images obtained were able to assist with the diagnosis and management of the retinal disorders.
The modified Spectralis HRA + OCT system is a safe and effective method that can be used reliably to obtain high resolution intraoperative multi-modality images for pediatric patients. The images obtained are able to assist in the diagnosis and management of a range of complex pediatric retinal conditions.
