“…Chung et al and Kim et al reported that the BCVA was significantly correlated with the mean retinal sensitivity around the macula in eyes with a resolved CSC [ 40 , 41 ]. Chiba et al showed that the BCVA was significantly correlated with the foveal sensitivity in macular thickening disorders [ 42 ]. Sugiura et al also reported similar results between the BCVA and macular retinal sensitivity, but this significant relationship was not observed when the retinal sensitivity was calculated from a wider retinal area in eyes with chronic CSC [ 43 ].…”

The purpose of this study was to evaluate the long-term effects of half-time photodynamic therapy (PDT) on the retinal sensitivity in eyes with chronic central serous chorioretinopathy (CSC). Twenty-two eyes of 22 patients with chronic CSC were studied. PDT was applied with full-dose verteporfin and half-time laser duration. The best-corrected visual acuity (BCVA) and retinal sensitivity in the central 2 and 10 degrees were evaluated at the baseline, and at 12 and 24 months after the half-time PDT. The retinal sensitivity was determined by Macular Integrity Assessment microperimetry (MAIA, Centervue, Padova, Italy). The results showed that the mean retinal sensitivities in the central 2 and 10 degrees were significantly improved at 12 months (25.6±2.79 dB, median; 26.11 dB, 25.6±2.25 dB, median; 25.65 dB, respectively; P<0.001) and at 24 months (26.3±2.62 dB, median; 27.38 dB, 26.6±2.21 dB, median; 27.45 dB, respectively; P<0.001) after the treatment compared to that at the baseline (19.2±3.93 dB, median; 19.34 dB, 20.9±2.92 dB, median; 20.9 dB, respectively). The BCVA was also significantly improved from 0.18±0.19 median; 0.15 logarithm of the minimum angle of resolution (logMAR) units at the baseline to 0.07±0.15 median; 0 logMAR units at 12 months (P<0.001) and to 0.049±0.16 median; -0.039 logMAR units at 24 months (P<0.001). We conclude that half-time PDT results in a significant improvement of the mean central retinal sensitivity for at least 24 months in eyes with chronic CSC. Thus, half-time PDT is beneficial in resolving chronic CSC for a relatively long period.

Influence of implantation of diffractive trifocal intraocular lenses on standard automated perimetry

Background This prospective comparative study aimed to investigate the influence of diffractive trifocal intraocular lenses (IOLs) implantation on standard automated perimetry. Methods Patients with no diseases affecting the visual field had undergone cataract surgery following the implantation of trifocal or monofocal IOLs from July 2019 to August 2020 were recruited. The normality of the anterior and posterior segments and absence of glaucomatous optic nerve cupping were confirmed preoperatively by slit-lamp examination. Standard automated perimetry was performed using Humphrey Visual Field 10–2 testing, 2–3 months after cataract surgery in only one eye per patient. The mean deviation (MD) and foveal sensitivity were compared between IOLs in eyes with acceptable reliability indices and best-corrected visual acuity of 20/25 or better. Results Among the 83 eyes of the 83 patients included, 39 and 29 eyes eligible for perimetry analysis had trifocal and monofocal IOLs, respectively. The mean MD and foveal sensitivity in eyes with trifocal IOLs were significantly lower than those in eyes with monofocal IOLs (P < 0.021), with mean differences of 0.77 and 1.01 dB, respectively. Conclusion The comparison in nonglaucomatous eyes demonstrated that the influence of trifocal IOLs on standard automated perimetry was greater than that of monofocal IOLs.
