Summary: This article discusses how urban policing, surveillance, and crime control in Geylang, Singapore contribute to the marginalization of excluded groups. By examining the intersection of political discourses, crime, and social control practices, it highlights the co-construction of class- and race-based inequalities in Singapore. The study identifies three key processes through which state power is manifested in Geylang, demonstrating how crime control policies legitimize urban political economy reliant on low-cost migrant labor.

Summary: This article examines the issue of recreational spaces for temporary, low-wage male migrant workers in Singapore and explores the politics of integration/segregation and inclusion/exclusion. The study reveals that state-provisioned recreation centers have unintentionally become contact zones that foster diverse urban encounters between migrants, locals, and state-linked agents. This phenomenon has been intensified during the COVID-19 pandemic.

Summary: This study aimed to report the incidence of age-related changes in drusen volume detected by optical coherence tomography (OCT) over a span of 6 years and their systemic and ocular associations. The results showed that the incidence of age-related macular degeneration (AMD) detected at 6 years was low. Drusen volume in the macular region either decreased, remained stable, or increased over the 6-year period. Older age, smoking, and chronic kidney disease were associated with decreased drusen volume, while older age and hypertension were associated with increased drusen volume.

Summary: Optical coherence tomography angiography (OCTA) parameters from both the retinal and choroidal microvasculature can be used to detect the presence and severity of diabetic retinopathy (DR). Choriocapillaris parameters show better discrimination between non-diabetic and diabetic without DR groups. Evaluating both retinal and choroidal microvasculature significantly improves the detection of diabetic retinopathy.

Summary: This study aimed to report the baseline characteristics and diurnal fluctuation of intraocular pressure (IOP) in a Chinese cohort of patients with glaucoma and ocular hypertension. The results showed that younger age, male gender, and thicker central corneal thickness were correlated with higher IOP in patients with primary open-angle glaucoma, while only thicker central corneal thickness was related to higher IOP in patients with ocular hypertension. Peak IOP occurred mostly in the early morning or late afternoon, and trough IOP occurred mostly in the early afternoon.

Summary: Glaucoma is a leading cause of irreversible blindness worldwide. Leukemia inhibitory factor (LIF), a member of the IL-6 cytokine family, has been shown to have neuroprotective effects in acute ocular hypertension (AOH). The present study found that LIF treatment inhibited retinal damage induced by AOH and reduced RGC loss and apoptosis. This effect was associated with the activation of STAT3 and mTOR/p70S6K signaling pathways. These findings suggest that LIF may serve as a potential neuroprotective agent in the treatment of glaucoma.

Summary: This study evaluated the influence of pilocarpine eyedrops on ocular biometric parameters and its effect on intraocular lens (IOL) power calculation in patients with primary angle-closure glaucoma (PACG). The results showed that pilocarpine eyedrops induced slight changes in ocular biometric parameters including axial length (AL), anterior chamber depth (ACD), lens thickness (LT), and lens position (LP). However, these parameter changes did not result in significant differences in IOL power estimation.

Summary: Mesenchymal stem cell-derived extracellular vesicles have neuroprotective effects in reducing retinal damage and increasing retinal ganglion cells, potentially through inhibiting cell apoptosis. In a rat model of chronic ocular hypertension mimicking glaucoma-induced optic nerve injury, we injected extracellular vesicles derived from umbilical cord mesenchymal stem cells into the vitreous cavity one week after injury, finding significant improvements in retinal damage and caspase-3 activation inhibition. These findings suggest the potential of mesenchymal stem cell-derived extracellular vesicles as a therapeutic approach for optic nerve injury caused by chronic ocular hypertension.

Summary: Retinal drusen are uncommon in IgA nephropathy, but they resemble drusen found in age-related macular degeneration. The IgA-staining deposits in the drusen are likely related to systemic deposition of IgA. The nature of cystic spaces in the drusen is still unknown. Further research on the retinas of people with glomerulonephritis is recommended.

Summary: The study investigated the phenotype, variability, and penetrance of IMPG2-related maculopathy. The results showed that mono-allelic IMPG2 variants could result in haploinsufficiency manifesting as a maculopathy with variable penetrance and expressivity. Family members of patients with IMPG2-related retinitis pigmentosa may also present with vitelliform lesions. The maculopathy is usually limited to the fovea and is associated with moderate visual impairment.
