Purpose: To report 1-year results of reduced-fluence photodynamic therapy (PDT) for polypoidal choroidal vasculopathy (PCV) in Japanese patients.
Design: Prospective interventional case series.
Methods: In the present study, 28 treatment-naïve eyes of 28 consecutive patients underwent PDT with a reduced laser fluence of 25 J/cm(2). Patients were followed up at baseline and 1 week and 3, 6, 9, and 12 months after PDT. Choroidal perfusion changes were evaluated by indocyanine green angiography (ICGA) and leakage from PCV lesions and exudative changes by fluorescein angiography and optical coherence tomography. Treatment safety was assessed according to visual acuity (VA) and adverse events. The best-corrected VA (BCVA) obtained by Landolt ring tests was converted into the logarithm of the minimal angle of resolution (logMAR).
Results: At baseline, the mean logMAR BCVA was 0.45 (geometric mean: 7/20). At 12 months, the mean logMAR BCVA significantly improved to 0.29 (geometric mean: 10/20) (P = 0.0001). The logMAR BCVA was stable or improved by >or=0.2 in 26 eyes (93%) at 1-year follow-up. In 10 eyes with VA better than 20/40 at baseline, the mean logMAR BCVA was significantly improved compared with baseline at 12 months. Although 16 of 28 eyes (57%) showed mild to moderate nonperfusion of choriocapillaris in early ICGA at 1 week, 27 eyes (96%) showed recovery to pretreatment levels at 3 months. Mean number of treatment sessions during the 12 months was 1.3. No severe side effects related to treatment were encountered.
Conclusions: Reduced-fluence PDT is an effective treatment for PCV and could improve vision even in eyes with VA better than 20/40.

Beijing Key Laboratory of Restoration of Damaged Ocular Nerve, Department of Ophthalmology, Peking University Third Hospital, Beijing 100191, China.
Aim: To investigate the influence of postoperative intraocular lens (IOL) positions on the accuracy of cataract surgery and examine the predictive factors of postoperative biometry prediction errors using the Barrett Universal II (BUII) IOL formula for calculation.
Methods: The prospective study included patients who had undergone cataract surgery performed by a single surgeon from June 2020 to April 2022. The collected data included the best-corrected visual acuity (BCVA), corneal curvature, preoperative and postoperative central anterior chamber depths (ACD), axial length (AXL), IOL power, and refractive error.

Purpose: This study aimed to comprehensively assess visual performance in eyes with idiopathic epiretinal membrane (iERM). Additionally, it sought to explore the associations between optical coherence tomography (OCT) imaging biomarkers and visual performance in patients with iERM.
Methods: In this prospective, non-interventional study, 57 participants with treatment-naïve iERM from the University of Turin, between September 2023 and March 2024 were enrolled.

Purpose: The purpose of this study was to analyze choroidal thickness (CT), along with macular thickness (MT), peripapillary retinal nerve fiber layer thickness (RNFLT), and macular vascular density (MVD) using swept-source optical coherence tomography (SS-OCT) in children with unilateral amblyopia, and compare the same with normal fellow eyes and normal eyes of normal children before and following occlusion therapy.
Materials And Methods: This was a prospective, longitudinal study of 60 children (4-18 years); 30 children had unilateral amblyopia and remaining 30 were normal. Group 1 consisted of 30 amblyopic eyes of children with unilateral amblyopia; Group 2 consisted of 30 fellow normal eyes of Group 1; Group 3 consisted of normal eyes of normal children.
