Multifaceted approach to evacuating multi-level premacular hemorrhage in a case of suspected Valsalva retinopathy - a case report.
BMC Ophthalmol
January 2025
Department of Retina and Vitreous, Narayana Nethralaya, #121/C, 1st R Block, Chord Road, Rajaji Nagar, Bengaluru, Karnataka, 560010, India.
Background: Accurate localization of premacular hemorrhages (PMHs) is crucial as treatment strategies vary significantly based on whether the hemorrhage resides within the vitreous gel, subhyaloid space, or beneath the internal limiting membrane (ILM). This report outlines the clinical features, diagnostic findings, and treatment outcomes in a patient diagnosed with a PMH secondary to suspected Valsalva retinopathy.
Methods: This is a retrospective interventional case report.
Retinopathy in Mucopolysaccharidoses.
Ophthalmology

Manchester Royal Eye Hospital, Manchester University Hospitals NHS Foundation Trust, Manchester, United Kingdom; School of Biological Sciences, Medicine and Health, The University of Manchester, Manchester, United Kingdom. Electronic address:
Purpose: To determine the pattern(s) of onset, variation, and progression of retinopathy in patients with Mucopolysaccharidosis (MPS).
Design: Prospective, longitudinal, observational study.
Participants: Between November 2015 and March 2023, individuals with MPS were recruited from Ophthalmology clinics at the Manchester Royal Eye Hospital, United Kingdom.
Optical Coherence Tomography Angiography: Investigating Vessel Density Changes Induced by Caffeine in Healthy Subjects.
J Ophthalmol

Department Eye Center, Duke University, Durham, North Carolina, USA.
Caffeine, the most widely consumed psychoactive drug globally, has been associated with vascular changes in various organs, including the retina. Researchers have reported vascular constriction in the retina in response to caffeine, although data on its effects remain limited and somewhat contradictory. Further research is needed to clarify the specific impact of caffeine on retinal blood vessels and its potential implications for ocular health.

Arthrosc Tech
October 2024
Department of Sports Medicine, the Second Hospital of Shandong University, Jinan, China.
Article Synopsis
- - Femoral head fractures, often occurring from high-energy impacts, can lead to traumatic hip dislocations and are classified into 4 types by Pipkin based on their location and associated damage.
- - Traditional treatment methods involve open reduction and internal fixation, which can be effective but also carry significant risks and complications.
- - The proposed arthroscopic technique for treating Pipkin type I fractures utilizes absorbable suture anchors for improved stability and involves a double-pulley and triangular suture bridge for secure fixation, representing a less invasive alternative.
Impact of Genetic and Environmental Factors on Peripheral Refraction.
Transl Vis Sci Technol
October 2024
Laboratorio de Óptica, Universidad de Murcia, Murcia, Spain.
Article Synopsis
- The study investigates how genetics and the environment affect refractive errors in both monozygotic (MZ) and dizygotic (DZ) twins by examining multiple eye measurements.
- The results show that MZ twins exhibit higher genetic influence in refractive errors compared to DZ twins, particularly for midperipheral defocus, indicating a significant role of genetics in peripheral vision.
- The findings suggest that while environmental factors influence central vision, genetic components play a bigger role in peripheral vision, highlighting the need for tailored approaches in managing conditions like myopia.
