Central bouquet hemorrhage with Henle fiber layer extension in myopic eyes.

Abstract

Objective: To characterize the clinical and multimodal imaging features of central bouquet hemorrhage (CBH) with Henle fiber layer (HFL) involvement in highly myopic eyes, and to investigate the relationships between hemorrhage characteristics, reabsorption time, and visual outcomes.

Methods: Multicenter, retrospective analysis of highly myopic eyes with CBH involving the HFL, confirmed by optical coherence tomography (OCT).

Results: Eighteen eyes from 18 subjects were included for analysis. The mean age of the cohort was 39 ± 13.7 years (range: 17-69) and 61% of subjects were female. Mean refractive error was -14.8 ± 3.14 diopters (range: -9 D to -22 D). All eyes demonstrated a combined CBH with HFL component, while a subretinal component was present in 83.3% of cases. Myopic choroidal neovascularization (CNV) was excluded in all eyes using optical coherence tomography angiography (OCTA) or dye-based angiography (fluorescein or indocyanine green). No correlation was observed between hemorrhage size and visual outcomes or reabsorption time. Hemorrhage cleared after a mean of 2.63 months, and the radial HFL hemorrhage component resolved first. All eyes showed improvement in visual acuity from baseline. Persistent OCT alternations after resolution of hemorrhage included ellipsoid zone disruption (88.9%) and hyperreflective changes in HFL (77.8%). Anti-VEGF injections were administered to 6 eyes (33.3%) and did not correlate with a significant visual or anatomical benefit.

Conclusion: CBH with HFL involvement in high myopia was associated with significantly improved visual outcomes from baseline but structural alterations can persist after clinical resolution. The size of the hemorrhage did not correlate with resorption time, and anti-VEGF treatment did not affect outcome. These findings provide new insights into the natural history and management of nonneovascular CBH in highly myopic eyes.
