Clinical Characteristics of Posterior Staphylomas in Myopic Eyes With Axial Length Shorter Than 26.5 Millimeters.
Am J Ophthalmol 2016; 162:180-190.e1AJ

Abstract

PURPOSE

To describe the features of posterior staphylomas in myopic eyes with an axial length shorter than 26.5 mm causing visual loss in old age.

DESIGN

Retrospective, observational case series.

METHODS

After reviewing cases of staphyloma, we isolated 16 eyes from 10 patients with an axial length <26.5 mm for further analysis. These patients had all undergone fundus photography and spectral-domain optical coherence tomography (SDOCT) and some had undergone 3-dimensional magnetic resonance imaging (3D-MRI).

RESULTS

The mean age of the patients was 70.0 ± 6.3 years (mean ± standard deviation; range 59-81). The mean axial length of the eyes with a posterior staphyloma was 25.14 ± 0.77 mm and the mean refractive error of the affected eyes was -4.28 ± 2.65 diopters. The median visual acuity was 20/60. All eyes presented with diffuse chorioretinal atrophy, which resembles pathologic myopic maculopathy. Fuchs spots previously were detected in 3 eyes (19%) and lacquer cracks in 2 (12%). SDOCT imaging of the macula showed decreased choroidal thickness in all eyes. A macular retinoschisis was detected in 5 eyes (31%), decreased ellipsoid zone reflectivity in 4 (25%), foveal retinal detachment in 2 (12%), a dome-shaped macula in 1 (6%), a choroidal neovascularization-related subretinal scar in 3 (19%), and loss of ellipsoid zone and outer nuclear layer in 3 (19%). The 3D-MRI scans from 8 eyes showed posterior staphylomas, lateral angulation, or protrusion in all eyes. No eye featured a tilted disc syndrome.

CONCLUSIONS

Posterior staphylomas in myopic eyes with an axial length shorter than 26.5 mm exhibit features resembling pathologic myopic maculopathy. This type of staphyloma might cause visual impairment in elderly patients and can be considered atypical forms of pathologic myopia in old age.
