Purpose To evaluate the changes of axial length (AXL) in eyes with unilateral idiopathic central serous chorioretinopathy (CSC) after subretinal fluid absorption. Methods We studied 31 consecutive patients with unilateral resolved central serous chorioretinopathy. The keratometric value and AXL were measured by partial coherence interferometry (IOL Master®). Presence of subretinal fluid and central macular thickness (CMT) were measured by spectral domain optical coherence tomography (Cirrus HD OCT®). Results The mean age of 31 CSC patients was 42.7 years, and 19 males were included. The AXL was statistically significant difference from 23.41 to 23.58 mm after subretinal fluid absorption (p < 0.001). The differences in AXL correlated with CMT differences (r = −0.616, p < 0.001). Best corrected visual acuity and CMT were statistically significant difference after subretinal fluid absorption (p < 0.001). Conclusions In unilateral idiopathic CSC, the AXL was increased after subretinal fluid absorption. Therefore, the impact of serous retinal detachment should be considered in AXL measurement.

Purpose To evaluate the change of axial length (AL) and the long‐term reproducibility measured by optical biometry and ultrasound A‐scan (US) after combined phacovitrectomy for macular‐on retinal detachment (RD). Methods Thirty‐seven eyes that underwent combined phacovitrectomy with intraocular lens implantation were analyzed, prospectively. The ALs were measured before surgery, after 1 year and 2 years, using optical biometry (IOL Master®, Carl Zeiss, Jena, Germany) and US. Intraclass correlation coefficient (ICC), coefficient of variation (CV), and test–retest standard deviation (TRTSD) were assessed. Results The mean age of patients was 56.5 ± 6.2 years, and 20 (54.1%) of the 37 were men. The mean preoperative AL measured by optical biometry was 25.03 ± 1.69 mm in vitrectomized eyes and 24.96 ± 1.70 mm in fellow eyes. The ICC, CV, and TRTSD were 0.97, 0.45 and 0.114 in vitrectomized eyes and 0.98, 0.66, 0.167 in fellow eyes, respectively. These parameters exhibit excellent long‐term reproducibility. Refractive prediction error by optical biometry and US were ‐0.41 ± 0.67 D (p = 0.001), and ‐0.49 ± 0.68 D (p = 0.000) respectively, which shows myopic shift. Correlation analysis showed significant relationships between myopic shift with shallow anterior chamber and thick lens. Conclusions After combined phacovitrectomy for macular on RD, the AL showed excellent long‐term intervisit reproducibility for two years. Regardless of AL, combined phacovitrectomy and gas tamponade resulted in significant myopic shift of postoperative refraction, for both optical biometry and US.

PurposeTo prospectively investigate the change in central macular thickness (CMT) and retinal nerve fiber layer (RNFL) thickness in eyes with Vogt‐Koyanagi‐Harada (VKH) disease in through 24 months follow‐up.MethodsTwelve eyes of 6 treatment‐naïve patients with acute VKH disease associated with optic disc swelling and serous retinal detachment and 30 eyes of 15 normal individuals were enrolled to investigate the changes of CMT and average RNFL thickness. Retinal thickness were measured at first visit and months 6, 12 and 24 via spectral domain optical coherence tomography (SD‐OCT).ResultsCMT was significantly lower in the eyes of VKH group at 12 (246.58 ± 21.80 μm vs. 258.60 μm ± 15.61, p < 0.05) and 24 months visit (226.67 ± 14.21 μm vs. 253.15 ± 15.84 μm, p < 0.05). RNFL thickness was significantly higher in the eyes of VKH group at initial visit, 6 and 12 months follow‐up visit, but no significant difference between VKH group and control group at 24 months follow‐up visit (95.83 ± 14.85 μm vs. 97.14 ± 12.97 μm, p > 0.05).ConclusionsThere were significant changes of CMT and RNFL thickness in the eyes with VKH disease during 24 months follow‐up period. Detecting or monitoring diseases including glaucoma and neuro‐ophthalmic diseases, which affect the retinal thickness in VKH patients, we recommend to consider the longitudinal change of the retinal thickness.
