The Optos 200Tx Scanning Laser Ophthalmoscope Application in Retinoblastoma Patients' Follow-Up.

Abstract

Methods A total of 1134 examinations with Optomap 200Tx were performed for 318 children who were clinically diagnosed with RB in the Ophthalmology Department of Tianjin Medical University Eye Hospital, China, between July 2015 and July 2017, and achieved stable disease lasting for more than 6 months after combined treatment. The children received examinations every 1-12 months (mean 4 months), initially at 31 months to 15 years of age (mean 51 months), and were given a full eye examination under anesthesia (EUA) immediately if recurrent tumor, recurrent vitreous seeding (VS), or recurrent subretinal seeding (SRS) was detected, or in the next follow-up visit if no abnormality was detected, and early treatment was performed when the lesion was confirmed. Results Recurrence was detected in 4 children in the examination with Optomap 200Tx, including 2 cases of recurrent vitreous seeding (VS) and 2 cases of recurrent subretinal seeding (SRS), which were confirmed by EUA and well controlled after early treatment. Conclusion The use of Optomap 200Tx in the long-term following up of patients with RB reduces the number of eye examinations under general anesthesia (EUA), increases the time between EUAs, and protects children from exposure to the adverse effects of general anesthetics. Optomap 200Tx can detect recurrent tumor and recurrent seeding, allowing for early treatment which produces better outcomes.
