Purpose: The aims of this study were: (1) to correlate posterior staphyloma with the ATN classification; (2) identify differences in clinical characteristics in terms of axial length (AL), age and best corrected visual acuity (BCVA) in eyes with the presence and absence of posterior staphyloma; (3) correlate the presence of posterior staphyloma with severe pathological myopia. Methods: This was a cross‐sectional and observational study developed in consecutive patients with high myopia. A complete ophthalmological examination, classification of myopic maculopathy according to the ATN grading system, staphyloma classification according to Curtin, and multimodal imaging tests (retinography, swept‐source OCT, autofluorescence and OCT‐angiography) were performed. Results: 336 eyes of 178 patients with high myopia were included. 71.4% of the sample were woman. The mean AL was 29.7 ± 2.6 mm (26–36.7). The mean age was 62.7 ± 13.1 years (27–92). The BCVA was 0.5 ± 0.3 (0–1). 238 eyes (70.8%) presented staphyloma; classifying 73.5% (n = 175/238) as simple and 26.5% as compound (n = 63/238). The most frequent types of staphylomas were type 2 and type 3, both present in 18.1% of the total (n = 43/238). Eyes with staphyloma had higher AL, worse BCVA and older age (p < 0.01), with no differences between sexes (p > 0.05). When differentiating between eyes with simple staphyloma and compound staphyloma, statistically significant differences were observed with respect to AL (p < 0.01), being higher in compound staphylomas. The severe pathological myopia subgroup (LA > 29.5 mm) presented a higher incidence of posterior staphyloma, with statistically significant differences (p < 0.01). Regarding the ATN classification, when analysing the eyes with the presence and absence of staphyloma, statistically significant differences (p < 0.01) were observed in the three components (atrophic [A], tractional [T] and neovascular [N]); having more advanced stages of A, T and N the eyes with staphyloma. Conclusions: Posterior staphyloma in highly myopic patients is a crucial finding in the progression of myopic maculopathy, being related to worse visual acuity, greater AL, older age and more advanced stages of the ATN classification. There is a higher prevalence of posterior staphyloma in eyes with severe pathological myopia. [ABSTRACT FROM AUTHOR]
