Purpose: To describe the retinal and vitreous changes in eyes showing myopic macular schisis (MMS) improvement when vitrectomy was not performed and identify triggering factors.
Design: Retrospective observational study.
Subjects: Patients with nonoperated MMS.
Article Synopsis
- The study aims to develop a deep learning model to automatically predict late recurrence of rhegmatogenous retinal detachment using ultra-wide field images.
- Researchers analyzed data from patients over 18 who underwent surgery for retinal detachment, training four different models on preoperative and postoperative images.
- The models achieved high accuracy rates (up to 91.1%) in predicting recurrence, highlighting potential risk factors like extensive laser retinopexy and asymmetrical staphyloma.
Article Synopsis
- This study examines long-term trends in Atlantic salmon growth over 49 years across five populations at their southern distribution, revealing a significant decline in growth since 1976.
- The research highlights the influence of both marine environmental factors and unique population characteristics on salmon life history, showing synchronous patterns of declining growth between southern and northern European populations.
- Findings indicate that early marine growth affects maturation decisions, with specific population dynamics influencing growth rates and suggesting that sex differences in growth thresholds are a conserved evolutionary trait.
Purpose: To the describe OCT imaging characteristics of a cohort of patients showing spontaneously closing degenerative or mixed type lamellar macular holes (LMH) and to compare them to the ones of a sex and age matched group showing stable lesions.
Methods: Patients diagnosed with degenerative and mixed type LMHs showing OCT-documented spontaneous anatomical closure were retrospectively selected from 3 specialized retina centres. An equal number of age and sex matching subjects were randomly selected among patients with anatomically stable lesions.

Purpose: To assess the capillary non-perfusion in different concentric sectors on widefield optical coherence tomography angiography (WF-OCTA) and to correlate the ratio of non-perfusion (RNP) to the severity of sickle cell retinopathy (SCR).
Methods: This retrospective, cross-sectional study included eyes of patients with various sickle cell disease (SCD) genotypes having undergone WF-OCTA and ultra-widefield color fundus photography (UWF-CFP). Eyes were grouped as no SCR, non-proliferative SCR or proliferative SCR.
