Study of the retinal imaging and output in premature baby under a computer-assisted binocular indirect ophthalmoscope.

PURPOSE: To explore a clear retinal imaging and output and enhance the development of retinopathy of prematurity (ROP) screening, which is safe and effective for ROP screening in premature infants. METHODS: A computer-assisted binocular indirect ophthalmoscope imaging and output system was equipped with camera and image processing hardware and connected to computers. The process of fundus examination was videotaped (photograph) and output. Simulated eyes were utilized to debug video head and acquire stable and clear fundus images by binocular indirect ophthalmoscope for premature infants. RESULTS: Fundus imaging output technique was sucessfully established. The common reasons of unclear imaging and corresponding solutions were summarized. This technique can capture and output stable and clear fundus images of premature infants. CONCLUSION: Assisted by hardware and software processing, a compute assisted binocular indirect ophthalmoscope imaging and output system was established, which can be used for screening, research, treatment and follow-up of ROP in premature babies to resolve the difficulty in obtaining clear fundus photograph.
