Prophylaxis for clinical macular oedema after phacoemulsification

The authors report on a retrospective cohort study looking at three different prophylaxis methods for macular oedema after cataract surgery: 1) Topical prednisolone acetate (PA) alone; 2) Topical PA in combination with non-steroidal anti-inflammatory drug (NSAID); 3) Intraoperative subconjunctival injection...

Systemic anti-inflammatory versus fluocinolone acetonide intraocular implant

In the Multicenter Uveitis Steroid Treatment (MUST) trial, 255 patients with intermediate uveitis, posterior uveitis or panuveitis were randomised to either fluocinolone acetonide intraocular implant or systemic corticosteroid therapy which was supplemented with immunosuppression if required. Patients were followed up...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

Differential inhibition of EAU by CTLA4 and IL-6

Cytotoxic T lymphocyte antigen-4 (CTLA4) binds both CD80 and Cd86 and inhibits T lymphocyte activation via CD28. Il-6 is a pleiotropic cytokine that has been associated with many autoimmune conditions including uveitis. Blockade of these molecules by either CTLA4-Ig, a...

Limbal melanocytes and the stem cell niche

The cornea is continually regenerated to maintain clear vision, due to a population of stem cells located in the limbal region between the cornea and the conjunctiva. These limbal stem cells (LESC) reside in crypts in structures called the Pallisades...

Statins inhibit TGFβ2 mediated fibrotic response in astrocytes

Glaucoma is a common condition where increased ocular pressure can lead to death of retinal ganglion cells due to impaired drainage of fluid from the eye. One mechanism involved in glaucoma is remodelling of the extracellular matrix at the lamina...

Could medical cannabis be used to successfully treat blepharospam?

This study observed the effect of medical cannabis in benign essential blepharospasm (BEB), in addition to standard botulinum toxin treatment. The study comprised of a retrospective chart review on eligible patients and included information on patient demographics, responses, cannabis history...

Hemianopia or visuospatial neglect: differences in information processing

It is widely reported that visuospatial neglect and hemianopia may be superimposed, and disentangling the two conditions can be pose difficulties for clinicians. The authors of this paper explored the differences in implicit information processing which is effective in patients...

Treatment for post stroke visual impairment – clinical practice versus literature evidence

The aim of this paper is to compare the treatments reported in a large scale stroke study (Vision in stroke (VIS) Study) against the treatments identified in a full systematic literature review. The purpose was to identify which treatment /...

IOP measures after intraocular chemotherapy

This study aimed to describe the relationship between intravitreal chemotherapy and IOP in children with retinoblastoma and identify risk factors for pronounced elevations. This was a retrospective study of ten cases (ten eyes) with 17 encounters overall. Mean age was...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

γδ T cell depletion does not affect fungal keratitis

Fungal keratitis (FK) is a blinding condition prevalent in agricultural areas of countries such as India and China. The fungus enters the cornea and induces an inflammatory response which leads to tissue damage. Neutrophils are the earliest infiltrating immune cells...
