Corneal cross-linking (CXL) is an option that in the last decade has demonstrated its efficacy and safety in halting the progression of keratoconus (KCN) and other corneal ectasias. Its indication has been extended beyond the classic definition that required evidence of KCN progression, especially in the presence of some risk factors for a possible progression (particularly the younger age). However, the results can be still somewhat variable today. There are several protocols, each with its own advantages and disadvantages...

Selective laser trabeculoplasty (SLT) has been widely used in the clinical management of glaucoma, both as primary and adjunctive treatment. As new evidence continues to arise, we review the current literature in terms of indications and efficacy, surgical technique, postoperative care, repeatability, and complications of this therapy. SLT has been shown to be effective in various glaucomas, including primary open-angle glaucoma (POAG), normal-tension glaucoma (NTG), steroid-induced glaucoma, pseudoexfoliation glaucoma (PXFG), and primary angle-closure glaucoma (PACG), as well as other glaucoma subtypes...

Hereditary retinal diseases are now the leading cause of blindness certification in the working age population (age 16-64 years) in England and Wales, of which retinitis pigmentosa (RP) is the most common disorder. RP may be complicated by cystoid macular oedema (CMO), causing a reduction of central vision. The underlying pathogenesis of RP-associated CMO (RP-CMO) remains uncertain, however, several mechanisms have been proposed, including: (1) breakdown of the blood-retinal barrier, (2) failure (or dysfunction) of the pumping mechanism in the retinal pigment epithelial, (3) Müller cell oedema and dysfunction, (4) antiretinal antibodies and (5) vitreous traction...

Diabetic retinopathy (DR) is the leading cause of blindness in industrialized countries. Remarkable advances in the diagnosis and treatment of DR have been made during the past 30 years, but several important management questions and treatment deficiencies remain unanswered. The global diabetes epidemic threatens to overwhelm resources and increase the incidence of blindness, necessitating the development of innovative programs to diagnose and treat patients. The introduction and rapid adoption of intravitreal pharmacologic agents, particularly drugs that block the actions of vascular endothelial growth factor (VEGF) and corticosteroids, have changed the goal of DR treatment from stabilization of vision to improvement...

Normal-tension glaucoma (NTG) is a progressive optic neuropathy with intraocular pressure (IOP) within the statistically normal range (≤21 mmHg). The prevalence of NTG varies widely among different population studies, being the most prevalent open-angle glaucoma subtype in some reports. The etiology of NTG possibly is multifactorial and still not well defined. Alternative treatments have been proposed based on pathogenesis details. However, in clinical practice, adequate reduction of IOP remains the keystone of managing patients with NTG...

INTRODUCTION: Many ocular diseases require intravitreal injections of pharmacological agents. Optimizing patients' experiences during injections is important to ensure compliance and maintenance of quality of life. The objective of this study was to identify strategies to help alleviate discomfort during intravitreal injections. METHODS: A cross-sectional study surveying 128 patients during clinic visits between 2014 and 2015 in two outpatient Retina Clinics (one academic and one private)...

INTRODUCTION: We describe a proactive method using electronic patient records (EPR) to identify pseudophakic patients with diabetic macular oedema (DMO) that might benefit from treatment with 0.2 µg/day fluocinolone acetonide (FAc; ILUVIEN(®)) implant. METHODS: Our EPR audit tool (Medisoft(®)) identified diabetic patients (May 2011-December 2014) with National Screening Committee-confirmed grade M1 maculopathy. Searches segmented this DMO patient population into patient groups who: (1) had received ranibizumab therapy, (2) had received ≥2 macular laser treatments, or (3) were unsuitable for macular laser or ranibizumab therapy...

INTRODUCTION: With the increasing use of intravitreal administration of corticosteroids in macular edema, steroid-induced intraocular pressure (IOP) rise is becoming an emergent issue. However, for patients in whom intravitreal steroids are indicated, there are no specific recommendations for IOP monitoring and management after intravitreal administration of corticosteroids. METHOD: An expert panel of European ophthalmologists reviewed evidence on corticosteroid-induced IOP elevation...

Trabeculectomy has been the gold standard in reducing intraocular pressure (IOP) in glaucoma patients, no matter it is angle closure or open angle glaucoma. However in primary angle closure glaucoma, no matter the lens is cataractous or not, it is likely to be pathological, this thicker than usual lens, with or without a more anterior position, is often regarded as a strong contributing factor to angle closure. Lens extraction, no matter it is cataractous or clear, can theoretically eliminate this anatomical predisposing factor of angle closure, and thus IOP can be reduced...

INTRODUCTION: Subhyaloid hemorrhage, whether spontaneous or in the context of a Valsalva maneuver, can lead to an acute decrease in vision when located in the premacular region. Nd:YAG laser hyaloidotomy (NYLH) is a minimally invasive treatment option. METHODS: We examined two different clinical courses based on two case reports of NYLH. One case report described a 52-year-old female patient who presented with a painless decrease of vision to 20/200. The fundoscopy verified a subhyaloid premacular hemorrhage...

INTRODUCTION: Patients with diabetic macular edema (DME), a chronic, vision-limiting condition, may be insufficiently responsive to standard-of-care anti-vascular endothelial growth factor (VEGF) and/or laser therapies. One approved treatment for such patients is 0.2 μg/day fluocinolone acetonide (FAc) sustained-release implant; however, data are limited for treatment strategies in patients with bilateral chronic DME insufficiently responsive to standard-of-care therapies. METHODS: Six pseudophakic patients with bilateral, chronic DME previously treated with laser and anti-VEGF therapy (and intravitreal triamcinolone acetonide in 10 eyes) were retrospectively investigated for visual and anatomical outcomes, 6 months post-0...

Malignant glaucoma remains one of the most challenging complications of ocular surgery. Although it has been reported to occur spontaneously or after any ophthalmic procedure, it is most commonly encountered after glaucoma surgery in eyes with prior chronic angle closure. The clinical diagnosis is made in the setting of a patent peripheral iridotomy and axial flattening of the anterior chamber. Intraocular pressure is usually elevated, but it may be normal in some cases. Although the exact etiology of this condition is not fully understood, several mechanisms have been proposed and it is thought to result from posterior misdirection of aqueous humor into or behind the vitreous...

BACKGROUND: Central vision loss caused by age-related macular degeneration (AMD) is the leading cause of blindness among the elderly in developed countries. Neovascular AMD is characterized by choroidal neovascularization (CNV). Growth of new blood vessels in patients with neovascular AMD is driven by a complex process that involves a signal protein called vascular endothelial growth factor A (VEGF-A). Anti-VEGF drugs that block this protein include ranibizumab, bevacizumab, and aflibercept...

Orbital changes in thyroid orbitopathy (TO) result from de novo adipogenesis, hyaluronan synthesis, interstitial oedema and enlargement of extraocular muscles. Cellular immunity, with predominantly CD4+ T cells expressing Th1 cytokines, and overexpression of macrophage-derived cytokines, perpetuate orbital inflammation. Orbital fibroblasts appear to be the major effector cells. Orbital fibroblasts express both thyrotropin receptor (TSHR) and insulin-like growth factor-1 receptor (IGF-1R) at higher levels than normal fibroblasts...
