This 47YO highly myopic female presented with 1.5 years of decreased vision in her left eye. Vision was 20/80 OD and counting fingers OS.
Color photography is fairly unremarkable, with a tessellated choroid with highly visible choroidal vasculature, central macular pigmentary loss, and a tilted nerve temporal peripapillary atrophy. However, the OCT reveals a dramatically different and complex picture, mostly a myopic posterior staphyloma.
Both inner and outer nuclear layer schisis are noted. The central outer macula is absent deep to the outer plexiform layer, with an outer macular lamellar hole. Bare RPE is present at the base of this optically empty region, which is demarcated by near-vertical pillars of apparent ellipsoid zone. The vitreous is partially detached with a premacular bursa and remains attached to the nerve and fovea, creating focal vitreomacular traction (VMT). Finally, there is temporal ganglion cell layer schisis. The underlying choroid is diffusely thinned, particularly within the staphyloma.
Management of myopic traction maculopathy (MTM) is stage-dependent, ranging from observation in early asymptomatic disease to surgery for progressive or vision-threatening lesions. Surgery is indicated for progressive vision decline, foveal detachment, macular hole (MH), and/or macular hole rhegmatogenous retinal detachment (RRD).
Learning Points:
Two complementary surgical approaches include 1) pars plana vitrectomy (PPV, to relieve tangential traction) with internal limiting membrane peeling (often fovea-sparing to reduce the risk of iatrogenic MH) and gas tamponade and 2) macular buckling, which counteracts the perpendicular tractional force of the posterior staphyloma (Takahashi et al, Prog Retin Eye Res2026;110:101434 and Serhan et al, AJO 2025;270:25-34). The two may be combined in advanced cases such as macular hole-related RRD.
Our patient’s pathology appears to be purely caused by staphylomatous changes and, according to the Myopic Traction Maculopathy Staging System (MSS), has a Stage 3aO+ macular schisis detachment (Parolini et al, Eur J Ophthalmol 2021;31:1299-1312). Ripa et al reported 98% and 100% foveal and retinal anatomic improvement, respectively, in such eyes following macular buckling.
