PurposeTo establish the normative ranges of macular ganglion cell layer (mGCL) and macular inner plexiform layer (mIPL) thickness using Spectralis spectral domain optical coherence tomography (SD-OCT) (Heidelberg Engineering, Inc., Heidelberg, Germany) in both Korean children and adults, and to determine factors associated with mGCL and mIPL thickness.MethodsWe conducted a retrospective, observational study of 573 healthy subjects (5–70 years old) who underwent comprehensive ophthalmic examinations in a single institution. Each inner retinal layer thickness was measured using SD-OCT and automatic segmentation software. Cross-sectional analysis was used to evaluate the effect of gender, age and ocular parameters on mGCL and mIPL thickness. Normative ranges of mGCL and mIPL thickness according to age, gender and factors associated with mGCL and mIPL thickness were measured.ResultsThe mean mGCL and mIPL thickness were 40.6±2.8 and 33.8±2.0 µm, respectively. Determinants of inner sector mGCL thickness were circumpapillary retinal nerve fibre layer (cpRNFL) thickness (β=1.172, p<0.001), age (β=−0.019, p=0.021) and male gender (β=1.452, p<0.001). Determinants of inner sector mIPL thickness were cpRNFL (β=0.952, p<0.001) and male gender (β=1.163, p<0.001). The inner sector mGCL and mIPL thickness increased significantly with age in children (β=0.174, p=0.009 and β=0.115, p=0.013), and then decreased in adults (β=−0.070, p<0.001 and β=−0.024, p=0.032). In the case of outer sectors, mGCL and mIPL thickness were not significantly related to age and gender.ConclusionsThis study ensured a normative range of the mGCL and mIPL thickness using Spectralis OCT. Gender, age and cpRNFL thickness significantly correlated with mGCL and mIPL thickness. This information should be considered in the interpretation of SD-OCT data.

Purpose: To evaluate affected choroidal regions and corresponding retinal changes in acute and recurrent central serous chorioretinopathy using swept-source optical coherence tomography. Methods: The foveal and subfoveal choroidal thicknesses were measured with swept-source optical coherence tomography. The retina was divided into five zones on the swept-source optical coherence tomography image based on baseline choroidal thickness being <100, 100–199, 200–299, 300–399 and ⩾400 μm. The retinal and choroidal thicknesses in the same five regions were evaluated during follow-up. The measurements were then compared between baseline (when central serous chorioretinopathy was active) and follow-up (after complete resolution of disease). Results: At baseline, in the acute group, the mean outer retinal layer thickness was significantly higher in areas with thicker choroid and lower in areas with thinner choroid. No such change was noticed in the recurrent group. In the acute group, the overall retinal thickness from baseline to follow-up decreased from 269.84 to 251.9 µm, ganglion cell layer thickness decreased from 107.14 to 101.28 µm, retinal nerve fibre layer thickness decreased from 56.96 to 49.33 µm, and no significant difference was noted in choroidal thickness. In the recurrent group, choroidal thickness significantly increased from 254.58 to 262.55 µm and ganglion cell layer decreased from 103.43 to 94.01 µm. No significant difference was noted in overall retina and retinal nerve fibre layer. Reduction in choroidal and retinal layer thicknesses was better in eyes which underwent laser treatment than the observation group. Conclusion: Swept-source optical coherence tomography might serve as an important non-invasive tool for both evaluating the extent of pathology and to predict the recurrence rate.
