“…Longer AXL and chorioretinal atrophy had close relationships with posterior staphyloma in high myopia. [9][10][11] Posterior staphyloma is recognized as an important factor in foveoschisis and foveal detachment without a macular hole. 7,8 Longer AXL, chorioretinal atrophy, and posterior staphyloma represent the outer ocular pouching forces resulting in pathologic changes.…”

Purpose To investigate the associated factors of foveoschisis and foveal detachment without macular hole in highly myopic eyes. Methods A cross-sectional study of 124 eyes of 68 highly myopic patients was performed. The patients underwent complete ocular examination, fundus photography, and optical coherence tomography (OCT). Results Of the 124 eyes, 10 (8%, 10/124) had foveoschisis or foveal detachment without a macular hole on OCT examination. On the basis of univariate analysis, six variables were associated with the pathologic changes, including age over 40 years (P ¼ 0.018), spherical equivalent over 10 D (P ¼ 0.042), axial length over 31 mm (P ¼ 0.001), macular chorioretinal atrophy (P ¼ 0.00003), posterior staphyloma (P ¼ 0.0003), and vitreoretinal interface factors, including epiretinal membrane, posterior vitreoschisis, and vitreomacular traction (P ¼ 0.00002). In the multivariate analysis, three factors were independently associated with foveoschisis and foveal detachment without macular hole in high myopia: axial length, macular chorioretinal atrophy, and vitreoretinal interface factors. Conclusions Foveoschisis and foveal detachment without macular hole are sight-threatening disorders in highly myopic eyes. Axial length, macular chorioretinal atrophy, and vitreoretinal interface factors were independently associated with these pathological conditions. Thus, both intraocular and outer ocular wall factors play important roles and merit further study.

“…The prevalence was reported to be 0.7% in the Blue Mountains Eye Study, 0.8% in the Handan Eye Study, and 1.6% in the Beijing Eye Study 21 – 23 . Further, it was reported to be 0.1% among Singaporean children aged 12–16 years 24 and 10.7% in patients with cataract in Saudi Arabia 25 . These reports suggest that the prevalence should be examined in association with age, sex, axial length (AL), and refractive error.…”

Myopia is increasing rapidly worldwide. We performed a cross-sectional study to investigate the prevalence of posterior staphyloma, a complication of myopia, and its shape characteristics in relation to age, sex, and axial length (AL) in a Japanese community-based cohort. The right eyes of 3748 participants who underwent fundus photography and optical coherence tomography (OCT) examination were evaluated. Posterior staphyloma prevalence was evaluated using fundus photographs and OCT images. Furthermore, fundus shapes were analyzed by measuring local fundus curvatures on 6 mm cross-line OCT images at intervals of 1 µm. The mean and variance of the curvatures were calculated to represent the fundus shape of each eye for investigation of the relationship between fundus curvature and age, sex, and AL. Seventy-seven eyes (2.05%) had posterior staphyloma. The mean and variance of the fundus curvatures were significantly greater in women than in men and became greater with age, suggesting that the shape of the staphyloma was steeper and less smooth in women and elderly subjects. AL and mean curvature showed a significant correlation (P = 2 × 10−16, R = 0.480), which was significantly affected by age (P < 2 × 10−16). Quantitative analysis of fundus shapes was useful for statistical analysis of posterior staphyloma in relation to age, sex, and AL.

“…2,3 The prevalence of posterior staphyloma varies depending on the study and the population analysed. For example, it has been found a 0.7% in the Blue Mountains Eye Study 4 (n=3654, age ≥49 years), a 0.8% in the Handan Eye Study 5 (n=6830, age ≥30 years), a 1.6% in the Beijing Eye Study 6 (n=4439, age ≥40 years), a 0.1% in Singaporean children 7 (n=1227, age 12-16 years) or a 10.7% in Saudi Arabia cataract patients 8 (n=629, age ≥40 years). A recent study carried out by Numa et al 9 indicated that the calculated prevalence in highly myopic eyes varies from 19% to 90%.…”

Purpose: To assess visual outcomes in high myopic eyes with nasal-inferior staphyloma implanted with a pseudophakic trifocal intraocular lens (IOL). Methods: We retrospectively analyzed the visual outcomes of 50 eyes of 45 patients who had cataract surgery after AT LISA trifocal IOL implantation. Twenty-five eyes diagnosed with posterior staphyloma (nasal-inferior, type IV and V), and 25 eyes as long eyes. Uncorrected distance visual acuity (UDVA) and corrected distance visual acuity (CDVA) values were used to assess the efficacy and safety of the surgery. Refraction and defocus curves were also evaluated at 6 months. Results: No intra-or post-operative problems occurred during the 6 months of follow-up. After the surgery, the mean Snellen decimal UDVA ranged from 0.50 to 1.00, and CDVA from 0.60 to 1.00 for both groups. CDVA was 0.91 and 0.74 for the long eye and nasalinferior staphyloma groups, respectively. Efficacy and safety indexes were 1.22 and 1.32 for the long eye, and 1.26 and 1.43 for the nasal-inferior staphyloma group, respectively. All eyes of both groups showed a postoperative spherical equivalent within ±1.00D. The long eye group showed the highest percentage of spherical equivalent between −0.13D and +0.13D (56%) and the nasal-inferior staphyloma group was between −0.51D and −0.14D (40%). Conclusion: The outcomes of the present study show that a trifocal IOL provides good visual acuity in high myopic eyes, being worse for nasal-inferior staphyloma eyes. The degree of tilt of the macular plane is related with the expected visual acuity.
