Proof of concept for using aqueous humour to detect retinoblastoma variant

A proof of concept study is presented with the aim of assessing the feasibility of using aqueous humour surrogate marker for tumour tissue for identifying retinoblastoma RB1 variant. Three children undergoing enucleation for retinoblastoma were recruited from a single centre....

Effect of heredity on risk of diabetic retinopathy

This study used survival analysis on 2199 patients who had reached vision-threatening diabetic retinopathy to investigate the contribution of heredity to diabetes together with other known risk factors for the development of either proliferative diabetic retinopathy (PDR) or diabetic macular...

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Effect of refractive corneal surgery on IOP and glaucoma progression

Accuracy of intraocular pressure (IOP) measurement depends on the biomechanical properties of the cornea, including its thickness central corneal thickness (CCT) and keratometry (K). Fifty-six eyes of 56 patients with primary open angle glaucoma (POAG) who had a history of...

Effects of blood donation on the physiology of the eye

Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...

Webinar will look at impact of menopause on eye health

A BCLA webinar will look at the impact going through the menopause can have on female eye health.

Brolucizumab in age-related macular degeneration, HAWK Study

The aim of the study was to collect additional data on efficacy and safety of brolucizumab 6mg intended for commercialization in age-related macular degeneration (AMD) (with an increase in pH and decrease in polysorbate concentration). The HAWK Study was a...

Resection versus plication impact on conjunctival-scleral thickness

In this study the authors aimed to compare the conjunctival-scleral thickness as measured with anterior segment (AS) OCT before and after medial rectus muscle resection or plication for exotropia. This was a prospective study of 7 resection cases and nine...

Bromfenac versus betamethasone in diabetic macular oedema

This is a randomised, prospective, single-centre trial in patients diagnosed with diabetic macular oedema (DMO) with central subfield thickness (CST) of 250-500µm, who refused anti-VEGF treatment. Nineteen eyes of 19 patients were randomised to bromfenac (BF) or betamethasone (BM) drops,...

Correlation between anti-retinal antibodies and proliferative vitreoretinopathy (PVR)

The pathological basis of PVR is not clearly understood and there are no effective medications targeting this condition. This cross-sectional study looked at the possible association of anti-retinal antibodies with patients with PVR and retinal detachment (RD). Aqueous and vitreous...

Cataract in patients with pseudoexfoliation syndrome

The authors present a prospective comparative study in 43 patients with (group 1) or without (group 2) pseudoexfoliation (PXF) undergoing cataract surgery. Anterior capsule samples were obtained in all patients and analysed for signs of apoptosis by using special staining...

Optical quality difference between monofocal and multifocal intraocular lenses

It is well known that multifocal intraocular lenses (IOLs) can generate more than one focus to restore distance and near vision, but patients may experience adverse optical phenomena such as decreased contrast sensitivity and induced glare or halos. The authors...
