REVIEW
Daniel S Narayan, Glyn Chidlow, John Pm Wood, Robert J Casson
Photoreceptors are the first order neurons of the visual pathway, converting light into electrical signals. Rods and cones are the two main types of photoreceptors in the mammalian retina. Rods are specialized for sensitivity at the expense of resolution and are responsible for vision in dimly lit conditions. Cones are responsible for high acuity central vision and colour vision. Many human retinal diseases are characterized by a progressive loss of photoreceptors. Photoreceptors consist of four primary regions: outer segments, inner segments, cell bodies, and synaptic terminals...

IMPORTANCE: This study highlights the efficacy and safety of trabeculectomy in Victoria, Australia. BACKGROUND: Trabeculectomy is currently the gold- standard in glaucoma surgery. However, its role has been increasingly questioned due to its associated risks and complications. This audit aimed to assess the efficacy and safety of trabeculectomy surgery in the state of Victoria, Australia. DESIGN: A cross-sectional, retrospective, and voluntary state- wide audit of trabeculectomy surgery by individual surgeons in 2012 with 24-months follow-up...

IMPORTANCE: Paracentral acute middle maculopathy (PAMM) as diagnosed by spectral domain optical coherence tomography (SD-OCT) may be associated with "patch off" visual loss post cataract surgery. BACKGROUND: To report a case series of severe vision loss due to PAMM after cataract surgery DESIGN: Retrospective case series. PARTICIPANTS: Cases from five surgical centres (public and private) in Victoria, Australia. METHODS: Retrospective analysis of cases with unexplained "patch-off" vision loss post cataract surgery...

BACKGROUND: This is a pilot study to test a polyethylene glycol (PEG) derived polymer used as a retinal patch to seal retinal breaks during pars plana vitrectomy (PPV) in the treatment of rhegmatogenous retinal detachment (RRD) in a porcine model. METHODS: Sixteen eyes from 8 pigs were assigned to 2 study groups (12 eyes) and one control group (4 eyes). In all study groups the polymer was used in-vivo, during PPV, to seal the break of a surgically induced RRD. Eyes in study groups were partially or completely filled with balanced saline solution at the end of the surgery...

BACKGROUND: The culture of retinal progenitors from an accessible adult stem cell source such as the limbus could provide a useful autologous source of retinal cell therapies. The human corneoscleral limbus contains multipotent stem cells that can be cultured as floating neurospheres. Previous work in rodents has demonstrated neuronal and photoreceptor differentiation from limbal neurosphere cultures. Here, we have examined undifferentiated cultured adult human limbal neurospheres as donor cells for retinal cell therapies by transplantation into a rat model of retinal degeneration...

REVIEW
Alexis Galeno Matos, Sanjay G Asrani, Jayter Silva Paula
Selective laser trabeculoplasty (SLT) has been indicated as a safe and efficient treatment for primary open-angle glaucoma; however, recent studies have also shown positive results with the use of SLT in some clinical conditions related to primary angle-closure glaucoma (PACG). Despite the potential benefits of SLT in selected cases of PACG, the mechanisms underlying the modifications in the trabecular meshwork tissue of patients with PACG are poorly understood. This narrative review approached both the current, limited knowledge about the histological changes observed in different forms of PACG and the clinical results of SLT treatment for PACG...

IMPORTANCE: Identifying risk factors for RION could promote a more conservative approach to radiation treatment planning in vulnerable patients. BACKGROUND: This study explored possible factors beyond radiation dose associated with the development of radiation-induced optic neuropathy (RION) after external beam radiation therapy. DESIGN: This was a retrospective case-control study conducted at a university hospital tertiary care center. PARTICIPANTS: Cases (nā€‰=ā€‰14) meeting criteria for a diagnosis of RION by neuro- ophthalmologic exam were identified from a single-center neuro-ophthalmology database...
