HtrA1 enhances cell senescence

A genetic basis for age-related macular degeneration (AMD) has been greatly advanced in recent years. The role of identified pathways such as complement factor H in AMD has been widely investigated. However, the effect of other gene variants identified by...

Nanoparticle administration of latanoprost

Glaucoma is a progressive optic neuropathy characterised by increased ocular pressure and loss of retinal ganglion cells. Conventional drug therapy with eye drops to reduce intraocular pressure (IOP) has variable bioavailability and can lead to ocular surface disease. In this...

Erythropoietin in healing corneal epithelial defects in rabbits

Corneal epithelial defects heal slowly in patients with diabetes, limbal stem cell deficiency and severe chemical burns. Erythropoietin is a glycoprotein hormone that promotes red blood cell proliferation and inhibits apoptosis of erythroid progenitors as well as nonhematopoietic cells. In...

Correlation between peak intraocular pressure following water drinking test and pulsed methylprednisolone therapy

Steroids have long been known to cause increased intraocular pressures (IOP) in susceptible patients. Intravenous methylprednisolone is used to treat many rheumatological conditions and one of the risks is raised intraocular pressure. It would be useful to find patients at...

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...

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)...

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...

Diclofenac versus Bromfenac after cataract surgery

Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly used after cataract surgery to reduce inflammation and cystoid macular oedema (CMO). Diclofenac 0.1% is used three to five times daily for 28 days and Bromfenac 0.09% twice daily for 14 days postoperatively. The...

Tear production levels and dry eye disease

Dry eye disease (DED) is multifactorial, caused by an alteration in the quality or quantity of tear film’s three layers. Several tests are available for diagnosis. The aim of this study was to determine if the Schirmer test (ST) could...

Vitrectomy in retinal detachment associated with choroidal detachment

Hypotony, posterior retinal breaks, longer axial lengths and total retinal detachments (RD) are risk factors for development of RD associated with choroidal detachment (RRDCD). This study retrospectively analysed the anatomic outcomes and prognostic factors of vitrectomy in 175 patients with...

How are pigment dispersion syndrome and pigmentary glaucoma inherited?

This single centre prospective, cross-sectional study assessed the relatives of patients with pigment dispersion syndrome (PDS) and pigmentary glaucoma (PG) to determine the heritability of these conditions over an 11 month period. One hundred and one unrelated patients with PDS...

Lens surgery in patients with lens subluxation misdiagnosed as primary angle-closure glaucoma

Lens subluxation can be caused by many conditions including Marfan syndrome and other hereditary conditions, and blunt trauma. Lens displacement can cause pupillary block and angle closure. This is commonly misdiagnosed as primary angle closure glaucoma (PACG), which can lead...
