REVIEW
Ejaz Ansari
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...

AIM: To investigate the expression differences of transforming growth factor-β2 (TGF-β2), basic fibroblast growth factor (bFGF) and intercellular cell-adhesion molecule-1 (ICAM-1) in lens epithelial cells (LECs) of complicated cataract with silicone oil tamponade and age-related cataract. METHODS: Totally 150 eyes of 150 patients (aged 35 to 77y) were investigated, including 75 patients with complicated cataract after silicone oil tamponade and 75 patients with age-related cataract...

PURPOSE: The purpose of this study is to assess the efficacy and safety of intracameral mydriatic solution, as compared to preoperative topical mydriatics, in patients undergoing manual small incision cataract surgery (MSICS) under peribulbar anesthesia. To assess the sustainability of intracameral mydriasis in MSICS by monitoring pupil size at specific junctures during the surgery. METHODS: This trial recruited 127 patients, who underwent MSICS under peribulbar block...

Posterior capsule opacification (PCO) is the most common complication after cataract surgery. So far, the only method for PCO treatment is the precisely focused laser surgery. However, it causes severe complications such as physical damages and neuron impairments. Here, a nanostructured photothermal ring integrated intraocular lens (Nano-IOLs) is reported, in which the rim of commercially available IOLs (C-IOLs) is decorated with silica coated Au nanorods (Au@SiO2 ), for high-efficient prevention of PCO after cataract surgery...

PURPOSE: To review the literature to determine the efficacy of available treatments for ocular adnexal lymphoma (OAL) and to evaluate the outcomes and complications of treatments in patients older than 13 years. METHODS: A literature search was conducted last in March 2017 in the PubMed and Cochrane Library databases for English-language original research investigations that evaluated treatment outcomes for OAL. The searches identified 307 unique citations, and 27 studies were selected according to the criteria outlined for this assessment...

The most common complication after cataract surgery is postoperative capsular opacification, which includes anterior capsular opacification (ACO) and posterior capsular opacification (PCO). Increased adhesion of lens epithelial cells (LECs) to the intraocular lens material surface promotes ACO formation, whereas proliferation and migration of LECs to the posterior capsule lead to the development of PCO. Cell adhesion is mainly mediated by the binding of integrin to extracellular matrix proteins, while cell proliferation and migration are regulated by fibroblast growth factor (FGF)...

PURPOSE: To report a case of rhegmatogenous retinal detachment in the late stage, despite the fact that it had previously been halted after intravitreal injection of an antimicrobial agent against endogenous bacterial endophthalmitis (EBE). CASE: This study involved a 62-year-old male who had previously been diagnosed with septicemia due to liver abscess and the detection of Klebsiella pneumoniae in a culture of his liver abscess, and who underwent ophthalmic examination after his conjunctival hyperemia had failed to improve...

Several glaucoma stents are available to surgically reduce the intraocular pressure in primary open-angle glaucoma (POAG). In comparison to conjunctival opening procedures, the advantages of microinvasive glaucoma surgery (MIGS) are relatively atraumatic ab-interno procedures through a paracentesis, conjunctival sparing for later filtrating surgery, and possible combined cataract surgery. In this overview, the principle of intraoperative indirect channelography as a decision criterion for the individual selection of glaucoma stent implantation is presented...

BACKGROUND: Individuals with Down syndrome have an increased risk for congenital cataracts, but descriptions of surgical, medical and developmental outcomes are sparse. MATERIALS AND METHODS: Retrospective review of medical charts of patients with Down syndrome with visits to Cincinnati Children's Hospital from 1988 to 2013 was performed. A case series of five patients with Down syndrome and cataracts is presented. A total of 47 patients with Down syndrome without cataracts were used as a developmental control...

A variety of refractive surgery techniques, which reshape the corneal stroma using laser energy, have been marketed as simple and safe alternatives to glasses or contact lenses. Laser-assisted in-situ keratomileusis (LASIK) is the most common of these procedures. Although there are few high-quality prospective studies of long-term outcomes, complications, or stability for refractive surgery procedures, there is at least general agreement that more than 90% of appropriately selected patients achieve excellent uncorrected distance vision...

REVIEW
Viral V Juthani, Elizabeth Clearfield, Roy S Chuck
BACKGROUND: Cataract is a leading cause of blindness worldwide. Cataract surgery is commonly performed but can result in postoperative inflammation of the eye. Inadequately controlled inflammation increases the risk of complications. Non-steroidal anti-inflammatory drugs (NSAIDs) and corticosteroids are used to prevent and reduce inflammation following cataract surgery, but these two drug classes work by different mechanisms. Corticosteroids are effective, but NSAIDs may provide an additional benefit to reduce inflammation when given in combination with corticosteroids...

PURPOSE: To assess the effect of preoperative risk stratification for phacoemulsification surgery on intraoperative complications in a teaching hospital. Design; Prospective cohort study. METHODS: Prospective assessment of consecutive phacoemulsification cases (N=500) enabled calculation of a risk score (M-score of 0-8) using a risk stratification system (Muhtaseb et al). M-scores of >3 were allocated to senior surgeons. All surgeries were performed in a public teaching hospital setting, Auckland, New Zealand, in early 2016...

PURPOSE: To compare surgeon experience and the outcomes of phacoemulsification using 2 different illumination techniques for cataract extraction. METHODS: A prospective interventional case series was performed on 20 consecutive patients (20 eyes) with senile cataract who underwent phacoemulsification enhanced with a 23-G endoillumination probe. The main outcome measures were the surgeon's perception of depth of field and quality of visibility of intraocular structures, ease of performance of the surgical procedure, effectiveness, and complications related to the procedure...

BACKGROUND: Descemet's membrane detachment (DMD) is one of the most serious complications of modern cataract surgery. We present an alternative technique for management of DMD with a review of the literature on current strategies for the treatment of DMD. CASE PRESENTATION: A 74-year-old woman developed DMD after phacoemulsification and failed the first descemetopexy with air tamponade. An alternative method was used to drain the pre-descematic fluid and reposition the detached Descemet's membrane in this rare case...

BACKGROUND: Pseudoexfoliation syndrome (PEXS) may go along with capsular bag shrinkage and luxation. In the present study, we focus on an association of isoforms of TGF-β with capsular bag luxation. METHODS: Aqueous humor was collected intraoperatively from 20 healthy controls and from 73 otherwise healthy patients with PEXS [PEXS without complications (PEX, n = 33), late PEXS with glaucoma (PEXG, n = 30) and with IOL and capsular bag luxation (PEXL, n = 10)]...
