BACKGROUND: Acute-onset postoperative endophthalmitis is an uncommon but potentially serious complication of cataract surgery. Since there are relatively few randomized clinical trials comparing the timing and administration of prophylactic antibiotics, there are wide variations in prevention practices around the world. METHODS: Literature review. RESULTS: Antibiotics may be used before surgery, during surgery, or after surgery in an attempt to decrease the rates of endophthalmitis...

We present the case of a 74-year-old Caucasian female who suffered sudden visual loss after routine phacoemulsification cataract surgery. The patient was subsequently diagnosed with non-arteritic anterior ischaemic optic neuropathy. The case is described in detail, and a concise review of the literature is presented together with the authors' view on the subject outlined. This is a very rare complication after cataract surgery even in high-risk patients with associated systemic co-morbidities. We suspect that the previous history of obesity, coronary artery disease, and arteriosclerosis contributed to the development of this serious ocular complication...

PURPOSE: While angle surgeries show good success in primary congenital glaucoma, reported success in glaucoma following cataract surgery (GFCS) and juvenile open angle glaucoma (JOAG) is variable and with relatively short follow-up. We evaluated longer-term outcomes of 360-trabeculotomy for medically-refractory GFCS and JOAG. DESIGN: Retrospective case series. METHODS: First operated eyes of consecutive patients with medically-refractory GFCS and JOAG in a single-surgeon pediatric glaucoma practice who underwent illuminated microcatheter-assisted 360-trabeculotomy from 2/2008-6/2015 were reviewed...

We describe the first case of a successful functional hemispherectomy in a patient with epileptic encephalopathy and a de novo collagen type IV alpha 1 (COL4A1) mutation. A 4-year-old girl was COL4A1 mutation-positive and suffered from drug-resistant epilepsy, hemiplegia, and developmental delay. Magnetic resonance imaging detected no porencephaly, and she had no cataract or renal abnormality. Following a presurgical evaluation for epilepsy, she underwent a functional hemispherectomy. She has been seizure free with no intracranial hemorrhage or other perioperative complications...

INTRODUCTION: Macular edema after cataract surgery (Irvine-Gass syndrome) or pars plana vitrectomy is a postoperative complication which can lead to permanent visual loss. Increased inflammatory substances, such as prostaglandins and cytokines, are discussed to be causative. Currently, there are no evidence-based guidelines for the treatment of postoperative macular edema. Intravitreal dexamethasone (DEX) could be effective by its anti-inflammatory effect. We examined the functional and morphological results of treatment with 0...

Posterior capsule opacification (PCO) is the most common complication that causes visual decrease after extracapsular cataract surgery. The primary cause of PCO formation is the proliferation of the residual lens epithelial cells (LECs). The mammalian target of rapamycin (mTOR) plays an important role in the growth and migration of LECs. In the current study, we used small interfering RNA (siRNA) to specifically attenuate mTOR in human lens epithelial B3 cells (HLE B3). We aimed to examine the effect of mTOR-siRNA on the proliferation, migration and epithelial-to-mesenchymal transition (EMT) of HLE B3 cells and explore the underlying mechanisms...

PURPOSE OF REVIEW: There are currently various options available for glaucoma treatment procedures ranging from laser to penetrating to nonpenetrating surgeries. Innovations in glaucoma surgical therapeutics include features such as external application, focused tissue effects, and minimal manipulation as these factors all help lower the risk of side-effects in addition to increasing the success rate of the treatment. Traditional diode laser transscleral cyclophotocoagulation (TSCPC) is invasive and destructive...

Myopia is not a simple refractive error, but an eyesight-threatening disease. There is a high prevalence of myopia, 80% to 90%, in young adults in East Asia; myopia has become the leading cause of blindness in this area. As the myopic population increases globally, the severity of its impact is predicted. Approximately one fifth of the myopic population has high myopia (≥-6 diopters), which results in irreversible vision loss such as retinal detachment, choroidal neovascularization, cataracts, glaucoma, and macular atrophy...

Risk reduction and the attainment of good outcomes in contemporary cataract surgery depend in part on patient compliance with a postoperative regimen of topical eye drops. Topical drops are expensive and challenging to instill properly for patients. The consequences of noncompliance or poor compliance can be significant for the patient (in the case of a complication) and for society (in the case of development of antibiotic resistance). For all of these reasons, new approaches that reduce the need for topical therapy are beginning to emerge, including intracameral injection, sustained or slow-release drug delivery mechanisms, and the recently introduced "Dropless cataract surgery," which involves intravitreal injection of single-use, compounded combination of antibiotics and corticosteroids...

Infectious endophthalmitis is an important cause of vision loss worldwide. This entity most often occurs as a complication of intraocular surgery especially following cataract surgery or intravitreal injection. Endophthalmitis is regarded as a serious complication following ocular surgery and the final visual outcome is fundamentally contingent on timely recognition and intervention. Intravitreal and oral antibiotics in combination with pars plana vitrectomy or vitreous aspiration remain the mainstay in the management of endophthalmitis...

An 18-year-old boy with an obsessive-compulsive disorder of eye rubbing presented with forme fruste keratoconus (KC) and posterior subcapsular cataracts. After evaluation, he underwent phacoemulsification in his left eye with intraocular lens implantation. The aggressive eye rubbing, however, aggravated the rapid progression to established KC, and further acute corneal hydrops within 3 months. Within the next 3 months, the eye rubbing precipitated rhegmatogenous retinal detachments (RDs) in both eyes. Furthermore, after undergoing a combined cataract and RD surgery with belt buckling and silicone oil endotamponade in his right eye, the repeated eye rubbing caused extrusion of the implanted silicone oil into the subconjunctival space and within the corneal stroma...

BACKGROUND: Post-operative endophthalmitis is a serious complication of intraocular surgery which may present acutely or chronically. Chronic post-operative endophthalmitis is characterized by decreased visual acuity, mild pain, and low-grade uveitis several weeks or months after intraocular surgery which may be responsive to corticosteroids, but recur upon tapering. Low virulence organisms such as Propionibacterium acnes are the most common culprit organisms, and treatment most often consists of both intravitreal antibiotic injections and surgery...

BACKGROUND: Congenital cataracts are often complicated by anterior segment dysgenesis. This study aims to compare bilateral anterior segment parameters, macular thickness, and best-corrected visual acuity (BCVA) in pediatric cataract patients at 3 months after unilateral cataract extraction with intraocular lens implantation. METHODS: Fifty-three pediatric patients with uncomplicated unilateral total cataracts were included. At 3 months post-surgery, bilateral corneal thickness at the thinnest location (CTTL), anterior chamber depth (ACD), and anterior chamber volume (ACV) were measured using Pentacam...

PURPOSE OF REVIEW: The purpose is to review the current and effective advantages of femtosecond laser-assisted cataract surgery (FLACS). RECENT FINDINGS: FLACS has advantages over manual phacoemulsification in its precision, and predictability and may be especially advantageous in difficult situations such as shallow anterior chamber, subluxated cataracts, white cataracts, and so on. However, the femtosecond capsulorhexis may not be as strong as a manual rhexis...
