Purpose: To comprehensively evaluate baseline characteristics of patients with central serous chorioretinopathy (CSC) and develop predictive risk scores to identify visual prognosis.
Methods: This single-institute, retrospective cohort study included 144 eyes of 144 patients with CSC who underwent photodynamic therapy and achieved serous retinal detachment resolution. We developed and assessed the performance of several risk scores for best-corrected visual acuity (BCVA) outcomes six months post-treatment: i) BCVA improvement (≤-1.
This study aims to develop a method to quantify choroidal vessels in normal eyes using wide-field optical coherence tomography (OCT) en-face images. The study included participants with normal eyes in whom wide-angle OCT images were acquired to generate planarized choroidal en-face and thickness map images. The images were segmented into central, midperipheral, and peripheral areas, and the midperipheral and peripheral areas were further segmented into supratemporal, infratemporal, supranasal, and infranasal sectors.

- The study compared the outcomes of two second-line treatments—intravitreal brolucizumab (IVBr) and photodynamic therapy (PDT)—for patients with polypoidal choroidal vasculopathy (PCV) who didn't respond to first-line treatments.
- Results showed no significant differences in best-corrected visual acuity (BCVA) or central macular thickness (CMT) between the two groups.
- Notably, a portion (20.8%) of the PDT group did not need further treatment afterward, indicating a potential advantage of PDT, although both treatments had similar overall effectiveness.
Article Synopsis
- The study investigates if colour scanning laser ophthalmoscope (cSLO) can predict systemic arterial stiffness, showing it has better image quality than traditional colour fundus photography (CFP).
- Researchers analyzed data from 54 patients, including various retinal parameters and cardio-ankle vascular index (CAVI) measurements, finding a strong correlation between the retinal artery sclerosis (RAS) index obtained through cSLO and CAVI.
- The results indicate that cSLO can serve as a non-invasive tool for early detection of systemic arterial stiffness, highlighting its potential in clinical settings.
This study aimed to investigate the relationship between macular shape and idiopathic macular hole (MH) findings using an objective method. We present retrospective observational case series on patients with MH. The shape of the macular area was quantified using quadratic equations, and the ocular shape (OS) index was calculated.
