Purpose: To identify factors predicting slow visual recovery following photorefractive keratectomy (PRK).

Methods: This retrospective study included consecutive patients who underwent PRK between January 2005 and December 2019 at Care Vision Laser Center, Tel Aviv, Israel. Myopic patients were divided into 2 groups according to whether they experienced normal recovery of visual acuity (within 60 days) or slow visual recovery (>60 days).

Introduction: In this case study, we present the "Ballerina" sign as a potentially valuable clinical indicator for detecting posterior capsular rupture (PCR) during cataract surgery. The purpose of this study is to highlight the significance of PCR in the context of cataract surgery and introduce this novel sign.

Case Presentation: During the cataract operation on a 70-year-old patient, we observed a spiraling fragment of the nucleus attached to a vitreous string.

Article Synopsis
  • The study aimed to gather nationwide data on the prevalence of 67 inherited retinal diseases (IRDs) in the Israeli population, as existing prevalence information is limited and can vary significantly.
  • Researchers collected data from 9,396 individuals diagnosed with IRDs through 10 clinical centers in Israel during May 2023, using specific diagnostic methods to ensure accuracy.
  • Results revealed that the most common IRD was retinitis pigmentosa (approx. 1 in 2,400), followed by other conditions like cone-rod dystrophy and Stargardt disease, with an overall prevalence of IRDs at about 1 in 1,043 individuals.

Behçet disease (BD) is a multisystemic disease that commonly involves the eyes. Although it affects patients in all age groups, data on ocular disease by age of onset are limited. This retrospective, multicenter study aimed to compare epidemiology, systemic and ocular manifestations, treatments and outcomes between three age groups: juvenile (<18 years), adult (18-39 years) and late (≥40 years) disease onset.

Objective: Much research has been conducted on the clinical course of posttraumatic stress disorder (PTSD), from the perspective of viewing it as a chronic disorder. In the present study, however, we propose viewing PTSD via the recovery paradigm, based on the sociointerpersonal model for understanding posttrauma, which offers a holistic and multidimensional definition of recovery and prognosis (Maercker & Horn, 2013). Specifically, the contribution to recovery of both self-disclosure as a personality trait and self-disclosure of traumatic experiences within the couple relationship were examined.

Purpose: To determine prevalence of probable polypoidal choroidal vasculopathy (PCV) among White patients with neovascular age-related macular degeneration (nAMD) using non-indocyanine green angiography (ICGA) criteria DESIGN: Multicenter, multinational, retrospective, cross-sectional study.

Methods: A total of 208 treatment-naive eyes from Hispanic and non-Hispanic White individuals diagnosed with nAMD were included. All underwent color fundus photography (CFP), optical coherence tomography (OCT), and fluorescein angiography (FFA).

Parents' resolution of their child's diagnosis is associated with parental sensitivity and secure child attachment. The Reaction to Diagnosis Interview (RDI) is the accepted measure for assessing resolution, but its administration and coding are time and labor intensive. This study examined the psychometric properties of the Reaction to Diagnosis Questionnaire (RDQ), a new self-report measure that assesses resolution.

Purpose: To evaluate retinal toxicity of ziv-aflibercept, a drug that had been approved for use for patients with colon cancer.

Methods: Twenty-two albino rabbits were injected intravitreally with 0.1 mL of ziv-aflibercept solution into the experimental eye and 0.

Background: Evolution preserves social attention due to its key role in supporting survival. Humans are attracted to social cues from infancy, but the neurobiological mechanisms for the development of social attention are unknown. An evolutionary-based, vertical-hierarchical theoretical model of self-regulation suggests that neonatal brainstem inputs are key for the development of well-regulated social attention.

Both emotional reactivity and categorization have long been studied within the framework of hemispheric asymmetry. However, little attempt has been made to integrate both research areas using any form of neuropsychological research, despite behavioral data suggesting a consistent relationship between affective and categorization processes. The primary goal of the current study was to examine the possibility of a laterally mediated interaction between emotional reactivity and the cognitive process of categorization.
