Neurotrophic Signaling, Sleep Physiology, and Retinal Neuroprotection: Integrative Mechanisms and Therapeutic Implications for Glaucoma

Sensory Neuroscience, EarlyView.
Glaucoma is increasingly understood as a neurodegenerative disorder shaped by sleep and circadian physiology, not intraocular pressure alone. Sleep loss and obstructive sleep apnea suppress BDNF–TrkB neurotrophic signaling, impair sleep‐dependent glymphatic clearance, and trigger microglial neuroinflammation and vascular insult at the optic nerve head,

Visual Improvement and Lowered Intraocular Pressure After Surgical Management of In-The-Bag Intraocular Lens Dislocation and Aphakia Correction; Retrospective Analysis of Scleral Suturing versus Retropupillary Fixated Iris-Claw Intraocular Lens During a 5-Year Period

Clinical Ophthalmology
Purpose We compare and evaluate the visual outcome and complication rate of two different techniques of surgical management of in-the-bag intraocular lens (IOL) dislocation or aphakia correction.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review

VIEW, EarlyView.
Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.

Gut microbiota dysbiosis in the inflammatory pathogenesis of diabetic retinopathy

VIEW, EarlyView.
This graphical abstract illustrates how gut dysbiosis drives diabetic retinopathy through the gut‐retina axis, a process unfolding in three interconnected stages. First, in the gut, a decrease in beneficial bacteria and an increase in pro‐inflammatory taxa compromise the intestinal barrier, causing a “leaky gut” that allows LPS to translocate into the ...

Double trouble: Bilateral spontaneous posterior dislocation of cataractous lens

Kerala Journal of Ophthalmology, 2018
Subluxation or dislocation of clear or cataractous lens occurs commonly following ocular trauma or in association with systemic or other ocular risk factors. Spontaneous dislocation of lens in the absence of any of these risk factors is very rare.

Posterior chamber intraocular lens dislocations and malpositions [PDF]

Australian and New Zealand Journal of Ophthalmology, 1989
AbstractDecentration and malposition of posterior chamber intraocular lenses (PC IOL) accounts for one of the remaining and unresolved conditions associated with the implantation of these lenses. This condition assumes importance Since in approximately 50% of cases where a PC IOL is removed there is an aspect of improper positioning.

Three hundred sixty‐degree prophylactic laser retinopexy versus focal laser during rhegmatogenous retinal detachment repair: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Purpose To compare the anatomic, functional and safety outcomes of intra‐operative 360‐degree prophylactic laser retinopexy versus focal laser retinopexy during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD) and to assess the certainty of evidence.

Infectious bacterial keratitis management in a Swedish region: Risk factors, treatment and time‐to‐resolution

Acta Ophthalmologica, EarlyView.
Abstract Purpose To report treatment patterns, time‐to‐resolution (TTR) and aetiologies of bacterial keratitis (BK) infections treated in a specialized hospital‐based cornea clinic in Sweden. Methods Retrospective study based on electronic health records screened during the period 2010–2019. The study included only culture‐confirmed cases of BK.

Longitudinal changes in bleb morphology following the PAUL Glaucoma Implant visualized using ultrasonography

Acta Ophthalmologica, EarlyView.
Abstract Purpose To evaluate bleb morphology longitudinally using sonography following glaucoma drainage device (GDD) surgery. Methods Prospective observational cohort study conducted from January 2022 to March 2024, with follow‐up up to 12 months postoperatively. Bleb morphology, including superior and inferior bleb height, transverse and longitudinal
