Purpose We investigated the natural course of the intraretinal hyperreflective ( IRH ) sign after macular haemorrhage ( MHE ) absorption in eyes with pathologic myopia. Methods This prospective observational cohort study evaluated 28 patients with pathologic myopia and MHE . The eyes were categorized into IRH and non‐ IRH sign groups according to IRH sign development. All eyes were evaluated; follow‐up visits were scheduled at 1, 3, 6, 12 and 24 months after MHE absorption. Results Of 28 patients (14 eyes each in the IRH and non‐ IRH groups), nine (32.1%) were men and 19 (67.9%) were women. The average age (mean ± SD ) was 46.64 ± 11.92 versus 52.71 ± 12.19 years in the IRH and non‐ IRH groups. The IRH sign coincided with the MHE invasion site. The sign persisted for the entire follow‐up period in all but two eyes, in which it disappeared at 12 and 24 months, respectively. Maximal MHE thickness was significantly greater in the IRH sign group (162.9 ± 67.84 versus 104.2 ± 32.34 μm, p = 0.013). The mean logarithm of the minimum angle of resolution visual acuity was significantly better in the non‐ IRH sign group at 12 (p = 0.029) and 24 (p = 0.033) months. The incidence of myopic traction maculopathies ( MTM ) was significantly higher in the IRH (57.1%) than in the non‐ IRH sign group (14.3%; p = 0.046). Conclusion The IRH sign can develop after MHE in pathologic myopia and can remain stable long after MHE absorption; furthermore, it is predictive of future MTM .
