Li Z, Wang W, Liu R, et al. - In this prospective, longitudinal, observational study involving 434 participants aged 7 to 70 years, researchers prospectively determined the effect of the choroidal thickness (CT) on the myopic maculopathy progression. The sample consisted of participants with bilateral high myopia (≤-6 D spherical error, range, −6 to −27.0 D) completed follow-up visits for 2 years. Using a swept-source optical coherence tomography, the baseline CT centred on the fovea was measured. Data reported that the mean baseline age, spherical equivalence and subfoveal CT of the participants were 23.2 ± 12.5 years, −10.50 ± 3.18 D and 153.20 ± 72.76 μm, respectively. Findings suggested that CT is an independent predictor for the progression of myopic maculopathy.
