Management of a giant pigment epithelium detachment with transition from half- to full-dose aflibercept

This case report describes the management of a giant pigment epithelial detachment (PED) in neovascular age-related macular degeneration (nAMD) using half-dose aflibercept. An 80-year-old woman presented with a huge PED (maximum height 1338µm) and multiple risk factors for retinal pigment...

RTP801 as a neuroprotective and axon regenerative treatment

This paper describes the neuroprotective and axon regenerative effects of siRTP801, which is a translatable small-interfering RNA (siRNA) targeting mTOR negative regulator; RTP801, through in-vivo and in-vitro models. In-vivo studies involved an optic nerve crush rat model with intravitreal injections...

DR-NET National DR Workshop in Tanzania: Policy, training and technology

Diabetic retinopathy (DR) is a leading cause of moderate to severe visual impairment (VI) and blindness worldwide, posing a significant public health challenge. As the prevalence of diabetes continues to rise globally, particularly in low- and middle-income countries (LMICs), the...

Effect of laser wavelength on delivering effective burns through opaque lens using pattern scan laser

Panretinal photocoagulation (PRP) has been used in the treatment of various retinal disorders for many decades. Conventional single-spot lasers take quite some time to do with significantly higher pain, anxiety and photophobia when compared to the pattern scan laser (PSL)....

OCT changes in chronic optic neuropathy

The authors evaluated optical coherence tomography (OCT) angiography in 10 patients who suffered various types of chronic optic neuropathies. Glaucoma is known to cause a decrease in peripapillary perfused capillary density on OCT angiography. However, other optic neuropathies have not...

Cybersight: Using OCT as an Approach to Diagnose Glaucomatous and Other Optic Neuropathies

Clinically, the difference between glaucomatous and simple optic atrophy of other origins is not always clear. OCT with the ability to image and measure inner retinal layers in the macula and peripapillary area, with the measurement of rim atrophy, is...

Renewed momentum in ocular gene and cell therapy, broadening application to chronic disease

Gene and cell therapies offer the prospect of ground-breaking new avenues for the treatment of diseases, reflected in a renewed explosion of interest and investment in retinal gene therapy. Rod McNeil reports recent clinical trial readouts across a diverse range...

RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

Pars plana vitrectomy for vitreomacular traction syndrome

This paper presents a meta-analysis and systematic review of the safety and efficacy of vitrectomy for vitreomacular traction (VMT), based on 21 eligible articles from 460 identified. A strength of this study is that it provided pooled analysis across a...

Understanding optic nerve head pericytes and glaucoma

The authors provide a comprehensive review of the current understanding of pericytes in the optic nerve head (ONH). Key points include: (1) Pericytes are contractile mural cells that play crucial roles in regulating blood flow, maintaining the blood-brain / blood-retinal...

Preoperative RPE alterations in macular holes

This retrospective interventional case series from Japan assessed whether preoperative alterations of the retinal pigment epithelial (RPE) in idiopathic macular holes correlated with postoperative functional and morphological changes in the macula. Fifty-nine eyes had preoperative Spectralis OCT using the ‘detailed’...

Prognostic information for PRP-naive patients

The Diabetic Retinopathy Study group demonstrated that pan retinal laser photocoagulation (PRP) reduces severe vision loss by up to 50% in cases of proliferative diabetic retinopathy (PDR). The authors of this current study aimed to provide information for laser naive...
