Popis: | Purpose: Optical coherence tomography (OCT) improved retinal assessment that is comparable to histopathologic sections. In retinoblastoma, OCT was reported to detect fovea-tumor relation, diagnose subclinical (new, residual and recurrent tumors), and suspect tumor spread into the optic nerve. We hypothesized that strategic incorporation of OCT into retinoblastoma management will improve outcomes and managing retinoblastoma at the subclinical level (clinically undetectable) provides means for less treatment burden. Methods: A single-center, noncomparative retrospective review of all eyes with subclinical retinoblastoma was conducted. Any eye that had an OCT-guided procedure, whether diagnostic or therapeutic, utilizing OCT software was included. OCT-guided management included projecting embedded OCT software tools (scan cube size and direction, multiple scan frames, localizing and measuring vertical and horizontal calipers, enhanced depth imaging frames, and/or red free fundus photograph) on a separate colored fundus image to guide management to improve visual, life, and eye salvage outcomes. Results: We used OCT-guided strategies in 83 children (114 eyes). Diagnostic strategies included posterior pole screening for invisible retinoblastoma (37 eyes), topographic localization of invisible tumors (15 eyes) or subclinical recurrence (29 tumors), topographic localization of fovea-tumor relation (31 eyes), and mapping of potential choroidal or optic nerve invasion to determine subsequent management (2 eyes each). Therapeutic strategies included laser photocoagulation for perifoveal residual (26) and invisible (11) tumors and verification of photocoagulation adequacy for invisible (11) new and recurrent (11) tumors. These procedures were scored for their influence to changed therapy. Conclusion: Detailed OCT assessment improves retinoblastoma management and facilitates precision therapy to preserve vital visual structures (e.g., the center of vision), detect subtle subclinical tumors (new or recurrent), allow administration and adequacy of laser treatment, and map subclinical high-risk features. Developing OCT-guided strategies with full technical description facilitates reproducibility and allows precision therapy to be a reality. Citation Format: Sameh E.
