Abstract

Purpose : To determine the prevalence of anisometropia of > 3 mm and associated factors among highly myopic (HM) patients.

Methods : We retrospectively analyzed a consecutive series of staphylomatous high myopia patients (≤ -6.00 D and/or > 25 mm axial length (AL) in at least 1 eye) who were seen a High Myopia Clinic between 1/2017-11/2017. All patients underwent dilated retinal exam, AL measurement, fundus photography/autofluorescence, and widefield swept source optical coherence tomography.

Results : 126 patients (89 female, 62 ± 13 years old, range 19-88) were included. Overall, when excluding unilateral eyes < 25 mm, AL was 29.6 ± 2.3 mm (25-36.7 mm). Severity of myopic macular degeneration (MMD) according to the Meta-PM classification was MMD Category (MMDCat) 1 in 48 eyes (20%), MMDCat2 in 83 (34%), MMDCat3 in 78 (32%) and MMDCat4 in 37 (15%). Among the 251 HM eyes, 44 had (18%) foveoschisis, 34 (14%) CNV, 10 (4%) macular/lamellar hole, 17 (7%) vitreomacular adhesion and 26 (10%) dome-shaped macula. Twenty of 126 patients (16%) had high anisometropia of ≥ 3 mm AL (range 3-11.2 mm). Of these 20 patients, among the shorter eye: AL was 26.0 ± 2.1 mm (23.3-30.24 mm), 2 eyes (10%) had peripapillary staphyloma, 1 (5%) had dome-shaped macula, 6 (30%) had wide macular staphyloma and the remaining 11 eyes had no staphyloma, Of the 5 eyes with AL < 24 mm, 3 were MMDCat0/1, however 1 was MMDCat3 with foveoschisis and Fuch’s spot, and 1 was MMDCat4 with dome-shaped macula and myopic choroidal neovascularization.

Conclusions : The shorter eyes in HM patients with anisometropia (based on refraction or AL alone) may have shorter AL attributable to dome-shaped macula or an eccentric, non-foveal location of the staphyloma apex, and therefore are also at risk of MMD changes.
