High myopia, staphyloma associated with macular anatomic abnormalities

Macular anatomic abnormalities were prevalent in eyes with high myopia and posterior staphyloma, according to a study.

Investigators used spectral-domain optical coherence tomography to gauge the prevalence of foveoschisis, foveal detachment, vascular traction, epiretinal membrane and macular hole in patients with high myopia. They also aimed to determine relationships between macular abnormalities and age, best corrected visual acuity, spherical equivalent, axial length and presence of posterior staphyloma.

Investigators prospectively analyzed 116 eyes of 72 patients with more than 8 D of myopia. Mean spherical equivalent was –15.04 D. Mean axial length was 28.88 mm. Mean BCVA was 20/60. Patients’ mean age was 38.89 years.

Macular anatomic abnormalities were observed in 22.41% of eyes with high myopia and in 53.65% of eyes with posterior staphyloma.

Foveoschisis, vascular traction and epiretinal membrane were significantly more prevalent in eyes with posterior staphyloma (P < .0001).

Foveoschisis was identified in 17 eyes (14.65%), vascular traction in 17 eyes (14.65%), epiretinal membrane in 13 eyes (11.2%), lamellar macular hole in two eyes (1.72%) and posterior staphyloma in 41 eyes (35.34%), the authors said.
