“…This suggests that the deformity of the eyes with pathologic myopia increases as the patient ages, which agrees with the findings in an earlier study on highly myopic eyes observed by stereoscopic fundus examinations. 9 However, this must be confirmed in a future study with a larger number of eyes.…”

PURPOSE. We analyzed the symmetry and pointedness of the posterior segment of highly myopic eyes. METHODS.We studied 234 eyes of 117 patients with bilateral high myopia (refractive error À8.00 diopters [D]) and 40 eyes of 20 patients with emmetropia (refractive error between À1.0 and þ1.0 D). Volume renderings of high-resolution magnetic resonance (MR) images were performed to obtain 3D images of the eye. To analyze the symmetry and pointedness of the posterior surface, a software was developed to measure the area and angle of a fan-shaped segment formed by selected points on the MR images.RESULTS. All of the emmetropic eyes were symmetrical in the horizontal and sagittal planes with no deformity. In highly myopic eyes, the shape was symmetrical in the horizontal plane in 146 eyes (62.4%) and in the sagittal plane in 162 (69.2%). The shape of the posterior pole was pointed (angle of fan-shaped segment <1508) in 45.7% and blunted (angle ‡1508) in 54.3% of highly myopic eyes. The most common shape was symmetrical in the horizontal and sagittal planes, and the posterior surface was blunt. The shape of the two eyes of the same individual was the same in 61 of 117 patients (52.1%). In 56 patients whose two eyes had different shapes, the most frequent pattern was a difference in the pointedness (51.8%).CONCLUSIONS. Quantitative assessments of the shape of eyes were useful in determining the pattern of eye shape deformity specific to pathologic myopia. (Invest Ophthalmol Vis Sci.

“…As myopia develops, the globe elongates axially. 12,19,20 However, elongation of the globe is not symmetrical throughout the posterior part of the eye. As reported by Moriyama et al, 21 highly myopic eyes are not simply elongated, but can have out-pouchings, and the shape of eyes with pathological myopia has several types of axial elongation observed by three-dimensional magnetic resonance imaging.…”

“…12,13 The development of posterior staphyloma is thought to be accompanied by stretching of the posterior fundus, resulting in various retinal lesions. 14,15 Our observations revealed that not only the retina but also the optic disc could be affected by stretching of the posterior fundus when the posterior staphyloma is close to the ONH.…”

Purpose To determine the morphologic features of the optic disc and the location of visual field (VF) defect in relation to posterior staphyloma in normal tension glaucoma (NTG) eyes with myopia. Methods One hundred and thirty-four NTG patients with myopia were enrolled. B-scan ultrasonography was performed in enrolled patients. Disc tilt ratio, disc torsion, and area of peripapillary atrophy were measured from disc photographs. Patients were classified according to the presence of posterior staphyloma and its location: staphyloma involving the optic disc, staphyloma involving either the supero-temporal side of the optic disc or the infero-temporal side of the optic disc. The relationship between the location of the posterior staphyloma and that of the VF defect was analyzed. Results Among 134 eyes, 74 eyes (55.2%) had posterior staphyloma on B-scan ultrasonography. Mean torsion degree was significantly greater in eyes with staphyloma involving the temporal side of the optic disc (19.78±18.001) compared with eyes with staphyloma involving the optic disc (4.65±4.921, P ¼ 0.001). The frequency of the location of VF damage differed significantly between eyes with staphyloma involving the supero-temporal side and those involving the infero-temporal side of the optic disc (P ¼ 0.008), which was not significant in eyes with staphyloma involving the optic disc (P ¼ 0.813).Conclusions Optic disc torsion was a prominent finding in myopic NTG eyes when posterior staphyloma was located temporal to the optic disc. The location of posterior staphyloma was related to the direction of disc torsion and the location of VF defect.

“…It is characterized by a refractive error of over –8.00 dpt associated with a number of variable degenerative fundus changes, but the staphyloma is considered to be the hallmark lesion [2,3]. Staphyloma types I and II – which affect the posterior pole and the macula, respectively – are considered to be the most frequent types [2,3].…”

Purpose: To evaluate the prevalence of and describe the pathology associated with macular bending (MB) defined as a smooth macular elevation found in optical coherence tomography (OCT) of patients with high myopia related to either dome-shaped macula (DSM) or the border of an inferior staphyloma. Procedures: We reviewed the 330 files of all highly myopic patients in our database that had had an OCT performed in the last 5 years. Main outcome measures were MB prevalence and its associated pathology. Results: Sixty-eight eyes from 45 patients (13.63%) presented MB; 23 bilateral, 40 in a posterior pole or macular staphyloma and 21 in an inferior staphyloma. Eighteen eyes presented choroidal neovascularization (CNV), 7 subretinal fluid without CNV, 11 retinoschisis and 3 a macular hole which had been stable for years. No differences were found in the rate of complications between patients with DSM or inferior staphyloma. Conclusions: MB is not an uncommon clinical feature. Associated pathology prevalence in MB was elevated and similar in posterior and inferior staphylomas.
