Purpose: To examine to what extent measurement of standard visual acuity allows prediction of other spatial vision measures on an individual basis when high correlations exist between visual acuity and the other measures.
Methods: A series of spatial vision functions were measured in a sample of 900 community-dwelling older observers. Regression analysis was performed, and correlation coefficients were calculated between standard high-contrast visual acuity and other spatial vision measures including contrast sensitivity, low-contrast acuity, low-contrast low-luminance acuity (SKILL card), and disability glare acuity.
Results: All measures were highly and significantly correlated with standard visual acuity (r = 0.68 to 0.91). Despite the high correlations, many predictions of the other spatial vision measures from the correlation with standard acuity fell considerably outside of acceptable ranges determined by repeatability. The influence of the range of values in correlations is emphasized.
Conclusions: Other spatial vision measures cannot be predicted on an individual basis from visual acuity despite high and significant correlations between the measures.

From pro-re-nata to fixed-interval regimen: evolving real-world treatment paradigms in anti-VEGF therapy for neovascular AMD.
Eye (Lond)
January 2025
Department of Medicine-Ophthalmology, University of Udine, Udine, Italy.
Objective: To evaluate the impact of evolving treatment paradigms for neovascular age-related macular degeneration (nAMD) by comparing outcomes between two patient cohorts treated with different anti-vascular endothelial growth factor (anti-VEGF) regimens over a decade apart.
Methods: This retrospective cohort study included 200 treatment-naive nAMD patients divided into two cohorts. Cohort 1 (2009-2010) was treated with a pro re nata (PRN) regimen, involving three initial monthly injections followed by as-needed treatments based on monthly monitoring.
Salivary steroids in acute central serous chorioretinopathy.
Int Ophthalmol
January 2025
University of Pittsburgh, UPMC Eye Center, 203 Lothrop Street, Pittsburgh, PA, 15213, USA.
Purpose: To analyze levels of salivary steroids, including 17-OH-progesterone (17-OHP), androstenedione, dehydroepiandrosterone, cortisol, cortisone, progesterone, testosterone, and estradiol, in patients with acute central serous chorioretinopathy (CSCR) patients.
Methods: Acute CSCR patients and healthy individuals were included in this observational case-control study. Levels of salivary steroids were determined by high-performance liquid chromatography with tandem mass spectrometry detection.
Association of digital eye strain with central corneal thickness: a cross-sectional observational pilot study.
Int Ophthalmol
January 2025
Department of Ophthalmology, Command Hospital, Pune, 411040, India.
Purpose: This study aimed to evaluate whether the digital eye strain (DES) was associated with the low central corneal thickness (CCT).
Methods: This observational cross-sectional pilot study was conducted from April 2023 to October 2023 at a tertiary eye care centre in North India, where CCT values were compared between subjects with DES and those without DES. Two hundred and eighty subjects (n = 280) aged 15-40 years with clear corneas and lenses were initially included in this study.
Thermal ocular burns and evaluation of associated limbal stem cell deficiency in the light of global consensus.

January 2025
Department of Ophthalmology, Ege University Faculty of Medicine, 35100, Bornova, Izmir, Türkiye.
Purpose: The aim of the present study is to examine the demographic data and clinical features of ocular surface injuries due to thermal burns and to evaluate LSCD in the light of global consensus.
Methods: Thirty-three eyes of 20 cases with ocular surface injury due to thermal burn who attended to the clinic between 2012 and 2023 were included in the study. LSCD severity was staged according to the global consensus which was published in 2019.
