Aim: To investigate the ocular development of patients who had unilateral congenital cataract (CC) combined with persistent fetal vasculature (PFV).
Methods: This cross-sectional, observational study included patients who had unilateral CC and PFV and those with isolated unilateral CC. Axial length (AL), keratometry, anterior chamber depth (ACD), lens thickness, and vitreous length were obtained. The ocular biometric parameters of the affected eyes of patients with CC and PFV were compared with the fellow eyes and with the affected eyes of patients with isolated CC.
Results: A total of 110 patients were included and divided into 4 groups: group 1 (18 patients with CC and PFV, <24mo), group 2 (22 patients with CC and PFV, ≥24mo), group 3 (35 patients with CC, <24mo), and group 4 (35 patients with CC, ≥24mo). The ALs of the affected eyes were shorter than those of the fellow eyes in group 1 (20.02±1.06 20.66±0.63 mm, =0.025). While the ALs of the affected eyes were longer than those of the fellow eyes in group 2 (23.18±2.00 22.31±1.06 mm, =0.044) and group 4 (22.64±1.80 22.02±1.01 mm, =0.033). The keratometries of the affected eyes were steeper than those of the fellow eyes in group 2 (44.78±1.66 43.83±1.38 D, =0.041) and group 4 (43.76±1.91 43.34±1.46 D, =0.043). No difference of ACDs between two eyes was found in all groups (all >0.05).
Conclusion: Compared with the fellow eyes, the ALs of the eyes with unilateral CC and PFV are shorter in patients younger than 24mo and longer in those older than 24mo; the keratometries of the eyes with unilateral CC and PFV are steeper in patients older than 24mo and similar with those younger than 24mo. These findings provide further understanding of ocular development in patients with both CC and PFV.

Therapeutic Potential of Crocin and Nobiletin in a Mouse Model of Dry Eye Disease: Modulation of the Inflammatory Response and Protection of the Ocular Surface.

Background: Dry eye disease (DED) is a multifactorial condition characterized by ocular surface inflammation, tear film instability, and corneal epithelial damage. Current treatments often provide temporary relief without addressing the underlying inflammatory mechanisms.
Objectives: This study examined the therapeutic potential of crocin and nobiletin, two naturally derived compounds with well-known antioxidant and anti-inflammatory properties, in a mouse model of DED induced by lacrimal gland excision (LGE).

Aim: To assess the possibility of using different large language models (LLMs) in ocular surface diseases by selecting five different LLMS to test their accuracy in answering specialized questions related to ocular surface diseases: ChatGPT-4, ChatGPT-3.5, Claude 2, PaLM2, and SenseNova.
Methods: A group of experienced ophthalmology professors were asked to develop a 100-question single-choice question on ocular surface diseases designed to assess the performance of LLMs and human participants in answering ophthalmology specialty exam questions.

Aim: To evaluate the prevalence of early post-traumatic stress disorder (PTSD) among young and middle-aged patients who have suffered open globe injuries, and to identify the psychosocial factors influencing PTSD in these patients.
Methods: A total of 280 patients who underwent ocular trauma surgery between January 2023 and January 2024 were selected through convenience sampling. Data were collected using a custom-designed demographic questionnaire, the Connor-Davidson Resilience Scale (CD-RISC), the Cognitive Emotion Regulation Questionnaire (C-ERRI), and the PTSD Checklist-Civilian Version (PCL-C).
Selective Tissue Penetration of the Corneal Layers of Cyclosporin 2% Associated with Miglyol in Rabbits.
J Ocul Pharmacol Ther
January 2025
Ophtalmology Department, Rouen University Hospital, Rouen, France.
Cyclosporin A (CsA) is a drug used to prevent immune rejection in corneal transplantation. Most grafts performed today are endothelial grafts which are complicated with poor penetration of CsA into the endothelium due to its hydrophobicity. To improve CsA penetration into the corneal a new ocular formulation of CsA 2% with Miglyol was developed and is commercially available.
