INTRODUCTION: This report describes the first known case of late-onset intrusion of an intrastromal ring segment into the anterior chamber due to posterior migration of a ring segment. To our knowledge, intrastromal ring segment penetration has only been shown to occur in the intraoperative or immediate postoperative period. We postulate that the perforation in this case is due to progressive thinning of the cornea, possibly in combination with habitual eye rubbing. CASE REPORT: A 44-year-old man presented with acute corneal hydrops related to penetration of Descemet's membrane and endothelium by an intrastromal ring segment implanted 7 years prior...

INTRODUCTION: Bromfenac is a well-known topical ophthalmic nonsteroidal anti-inflammatory drug (NSAID) that is commercialized in the USA and other regions of the world. A new formulation, 0.075% bromfenac in DuraSite®, was developed to treat postoperative inflammation and reduce pain in patients who have undergone cataract surgery. We hypothesized that efficacy and safety would be enhanced with twice-daily (BID) dosing compared to once-daily (QD) dosing. METHODS: This was a multicenter, double-masked, comparative study in which 40 and 45 subjects were randomized to groups receiving BID dosing and QD dosing, respectively...

Keratoconus management has significantly changed over the last two decades. The advent of new interventions such as cornea cross-linking, intrastromal corneal ring segments, and combined treatments provide corneal clinicians a variety of treatment options for the visual rehabilitation of keratoconus patients. This review summarizes current evidence for these treatments and highlights their place in keratoconus management while new promising emerging therapies are being investigated.

For several years, the gold standard for surgical treatment of glaucoma has been trabeculectomy. Although very successful at reducing intraocular pressure (IOP), there are several potential complications of trabeculectomy, including sight-threatening ones. This has stimulated much research aimed at the development of new and effective procedures to lower IOP with an enhanced safety profile. Minimally invasive glaucoma surgery (MIGS) procedures prioritise patient safety but also demonstrate efficacy in reducing IOP...

INTRODUCTION: Tumor necrosis factor-α (TNF-α) is a multifunctional, proinflammatory cytokine that mediates pleiotropic biological functions, especially inflammation and immunoregulation. We hypothesized that blocking TNF-α with a monoclonal antibody would decrease inflammation and subconjunctival scarring in an animal model of experimental filtration surgery. METHODS: In a randomized, prospective, masked-observer study, 30 New Zealand albino rabbits underwent glaucoma filtration surgery...

INTRODUCTION: Povidone-iodine aqueous solution is an antiseptic commonly used in ophthalmology for treatment of the ocular surface. Dimethylsulfoxide (DMSO) is a well-known skin penetration enhancer that is scarcely utilized in ophthalmic drug formulations. We describe here a low-dose formulation of 0.25% PVP-I in a gel containing DMSO for the treatment of Demodex blepharitis. CASE REPORT: A 95-year-old female presented with chronic blepharitis involving both the anterior and posterior eyelid margins...

Glaucoma is the leading cause of irreversible blindness worldwide, affecting 64.3 million people. An estimated 60.5 million people are affected by primary open angle glaucoma globally, and this will increase to 111.8 million by 2040. The definition of glaucoma has evolved greatly over time. Although multiple risk factors such as ischemia, inflammation, myopia, race, age and low ocular perfusion pressure may play a role, intraocular pressure (IOP) is still the main risk factor we can easily identify and modify...

INTRODUCTION: Ranibizumab is an inhibitor of vascular endothelial growth factor-A (anti-VEGF) approved for the treatment of neovascular age-related macular degeneration (nAMD). The treat and extend (T&E) regimen can potentially reduce the burden of clinic visits compared with a pro re nata (PRN) regimen. Retrospective, interim analyses of clinical effectiveness, treatment and resource use patterns were conducted using real-world data in England and Wales from the TERRA study. METHODS: Two cohorts, those switching from a PRN to a T&E regimen ('prior PRN') and those initiating ranibizumab on the T&E regimen as their first anti-VEGF therapy ('anti-VEGF-naïve') were enrolled in TERRA...

Cystinosis is a rare autosomal recessive disease with an incidence of approximately 1 case per 100,000-200,000 live births. Over the years, gaining in-depth knowledge of the disease has led to vast improvement in patient life expectancy. However, debilitating, extra-renal manifestations such as eye disease, in particular corneal crystal deposition and its associated photophobia, still occur frequently, regardless of patient age and notwithstanding the increased implementation of systemic therapy. Ophthalmological assessment has not yet been standardized...

REVIEW
Maria Gemenetzi, Praveen J Patel
Despite significant progress in retaining vision for neovascular age-related macular degeneration patients in the era of treatment with intravitreal anti-VEGF agents, there is no universally accepted treatment regimen that defines the frequency of treatment needed to achieve the optimal visual outcomes while simultaneously balancing the burden of long-term, frequent and high-cost treatment. Treat and extend has recently and consistently been used by retina specialists to minimise the financial and psychological costs of the need for frequent treatment with anti-VEGF injections...

Age-related macular degeneration (AMD) is a multifactorial disease and a leading cause of vision impairment in elderly people in Western society. Geographic atrophy (GA), the late stage of dry AMD, is typically defined as a round or oval area of atrophy of 175 µm or more. In GA patients, visual acuity (VA) can still be good if the macula is spared, but decreased if GA extends through the fovea causing a great impairment of quality of life. Because of a poor correlation between VA and GA lesions or progression, a multimodal imaging approach is necessary to better follow up GA patients...
