Glaucoma and cigarette smoking: a review of narrative reviews

Background: Glaucoma is an optic neuropathy associated with visual field changes for which high intra-ocular pressure is a major risk factor. Emerging research indicates that modifiable factors, among which the cigarette smoke, besides IOP may be associated with the presence of glaucoma. Objective: The objective of the study was to perform a review of narrative reviews to examine on the relationship between cigarette smoking and glaucoma. Methods: The results of all narrative reviews in the scientific literature about glaucoma and tobacco smoking were analyzed. A quality assessment was performed according to an easy and convenient tool for the quality assessment of narrative reviews for systematic reviews (International Narrative Systematic assessment) the INSA tool. Literature searches were performed using PubMed. Results: 20 studies about relation between glaucoma and smoke were collected, no restriction language was applied. 15 of these studies have been excluded. We selected among them 5 reviews. With the INSA tool we measured the quality of the 5 selected narrative reviews. Studies that had a highest score with the INSA tool were two: A. Coleman et al. “Risk Factors for Glaucoma Needing More Attention” and R. Salowe et al. “Primary Open-Angle Glaucoma in Individuals of African Descent: A Review of Risk Factors”. Conclusion: The narrative reviews analyzed underline that there is no definitive association between cigarette smoking

Ropivacaine vs tetracaine in topical anesthesia for intravitreal injection

Aim: The object of the study was to evaluate the long term efficacy and safety of ropivacaine 0,5% vs tetracaine 0,5% for topical anesthesia in intravitreal injection of dexamethasone in patients with diabetic macular edema (DME) and anti-vascular endothelial growth factor (VEGF) therapy. Methods: Thirty-seven patients were enrolled in the study. Intravitreal anti-vascular endothelial growth factor (VEGF) and Dexamethasone were placed in DME patients. Intravitreal administration determines appropriate and long-lasting drug's concentration without systemic side effects. Topical anesthesia under ropivacaine 0,5% vs tetracaine 0,5% was performed. Results: Intravitreal injection without any supplemental anesthesia and sedation was realized. Patients reported mild pain (recorded by a 0 to 10 scale) during the procedure with optimal operative result. Conclusions: Topical anesthesia with ropivacaine and tetracaine is safe and effective in intravitreal injection. The long-lasting anesthesia secured low pain during this limited but unpleasant procedure

Suspensory materials for surgery of blepharoptosis: a systematic review of observational studies

Background Frontalis suspension surgery is considered the procedure of choice in cases of blepharoptosis. Among all the materials used in this type of surgery, ophthalmic and plastic surgeons prefer to use autologous Fascia Lata. However, during years, other autogenous and exogenous materials have been introduced. Objectives The aim of this study was therefore that of systematically reviewing the functional results and the rate of complications of different synthetic materials, as compared to autogenous Fascia Lata. The primary objective was to determine the rates of Successful Surgeries (SSs) of these materials. The secondary objective was to assess the onset of complications. The following materials were investigated: Fascia Lata, Mersilene, polytetrafluoroethylene (PTFE) and Silicon. Data Source and Methods Following the Prisma procedure, on January 30th, 2016 we used the following electronic databases to select the studies: MEDLINE and Scopus. Results The search strategy retrieved 48 publications that met the eligibility criteria of the systematic review. All studies were non-comparative. PTFE (n = 5) showed the best rate of SSs among the materials compared (statistically significant). Surgeries performed with autogenous Fascia Lata (n = 19) had a 87% rate of success those performed with Mersilene (n = 12)had 92% and those performed with Silicon (n = 17)88%. PTFE had the best outcome, with 99% success rate. As for complications, surgeries performed with PTFE had a higher rate of suture infections (1.9%) as compared to Fascia Lata, but lower incidence for all other complications. Conclusions Although most studies were good quality cohort studies, the overall quality of this evidence should be regarded as low due to their non-comparative design. Our data suggest that PTFE seems to be the most valid alternative material for frontalis suspension surgery, with low recurrence rates and good cosmetic and functional results

Results of case-control studies supportthe association between contact lens useand Acanthamoeba keratitis

Acanthamoeba keratitis (AK) is ever more frequently reported in industrialized countries. The loss of the corneal surface integrity consequent to secondary microtrauma produced by the use of contact lens (CL) favors the penetration of the parasite into the corneal tissue. A scientific review was performed to investigate the association of CL wear as an Acanthamoeba keratitis (AK) risk factor. A computerized screening of 7834 Medline articles (4623 from PubMed; 3211 from Scopus) used a strict selection criteria of case-control studies involving CL wear and/or trauma. The search yielded five case-control studies published from 1995 to 2012. All studies included showed a statistically significant positive association between AK and CL use, with a combined odds ratio (OR) of 10.21 (95%, confidence intervals [CI]; 3.57-27.64). All studies included showed a statistically significant positive association between AK and CL use, though with differing OR values. Though rare, AK should be held in higher consideration when ophthalmologists are faced with CL users exhibiting simplex-like lesions associated with circular stromal infiltrates and disproportionate ocular pain in respect to the objective clinical picture.Abstract BACKGROUND: Acanthamoeba keratitis (AK) is ever more frequently reported in industrialized countries.

Differential activity and clinical utility of latanoprost in glaucoma and ocular hypertension

Background: The purpose of this study was to demonstrate the hypotensive efficacy and tolerability of latanoprost when used as monotherapy and as polytherapy associated with antiglaucomatous medication proven to be ineffective in keeping intraocular pressure under control. Methods: Three hundred and thirty-seven patients (672 eyes) affected by primary open-angle glaucoma and intraocular hypertension were recruited over a period of 10 years from the Glaucoma Centre, Department of Ophthalmological Sciences, University of Rome "Sapienza", and treated, subject to informed consent, with latanoprost 0.005% alone or in combination with other ocular hypotensive drugs. The patients were followed during this period at regular intervals, with determination of visual field, fundus oculi, visual acuity, and eventual onset of local and systemic side effects. Results: Latanoprost used as monotherapy and as polytherapy renders possible optimal and durable control of intraocular pressure in the form of one antiglaucomatous drug because it can substitute for one or more drugs and obtain the same hypotensive effect. Conclusion: Latanoprost can be described as the ideal hypotensive drug, not only because of its ideal compliance profile (only one daily dose in the evening), excellent hypotensive effect, and, above all, few systemic side effects. © 2012 Pacella et al, publisher and licensee Dove Medical Press Ltd

Association between smoking and uveal melanoma: a systematic review

Background: The aim of this study is systematically review the scientific literature on the relationship between tobacco smoking exposure and UM. Methods: The search was performed on Medline and Scopus databases. For each database, we used the following query: “smok* AND (eye OR uveal) melanoma”. Results: 3 observational studies were considered suitable, two case-control studies and one cohort study. There is no significant evidence in the scientific literature about the association between smoking and UM. Conclusions: More complete and multi-center studies are desirable, giving the importance of smoking as a risk factor in the development of cancers

Epidemiology of syphilis: new cases of neurosyphilis

Abstract The Authors report three cases of ophthalmic neurosyphilis in patients who complained a visual decrease monocular. The diagnosis was performed with physical and fundus examination, electrophysiological, hemato-chemical and microbiological tests, fluorangiografy and RMN. The physical examination provided standard results about eyes interested while the fundus examination, as well as the electrofunctional and fuorangiografy examinations, showed some alterations. The sockets and encephalon RMN were normal. Moreover; the patients were submitted to specific haematic and microbiological laboratory tests which showed positivity for syphilis. To sum up all patients received an incidental diagnosis of syphilis. This trend could be attributable to an extensive use of antibiotics that changing the natural course of disease, mask clinical evidences and make them harder to diagnose

Efficacy and safety of the intravitreal treatment of Diabetic Macular Edema with Pegaptanib: a 12-month follow-up

This observational study was performed to evaluate the efficacy and safety of intra-vitreal injections of pegaptanib during a 12-month follow-up period. Forty eyes (20 patients) affected by diabetic macular edema were monitored. Twenty were subjected to treatment, and 20 were controls. The treatment involved a cycle of three intravitreal injections of pegaptanib (0.3 mg every 6 weeks), at the end of which treated patients were submitted to a monthly follow-up for a period of 12 months. The aim was to evaluate the clinical condition of the eye after therapy and gauge the efficacy of the long-term use of this drug. Specific criteria were used to measure the efficacy and safety of pegaptanib. Regarding efficacy, we considered the following: an average improvement in the power of vision, or visual acuity, of →10 letters (2 lines), equivalent to an average logMAR score of →0.2, and a reduction in the central macular thickness of →250 μm. Regarding safety, we considered the occurrence of undesired eye and systemic side effects correlated to either the drug itself or the injection procedure. The logMAR score for the measurement of visual acuity at T3 (third intra-vitreal injection at week 13) with respect to T0 decreased from 0.7 ± 0.277 to 0.445 ± 0.216, suggesting an improvement, while the mean Early Treatment Diabetic Retinopathy Study (ETDRS) score increased from 25.75 ± 13.046 to 34.300 ± 11.770 letters. The central macular thickness was reduced from the initial value of 746.95 ± 293.601 to 334.050 ± 93.997 μm. In seven controls, we registered a worsening both in terms of visual acuity and macular thickness in some eyes, justifying a continuation of therapy in eight eyes of the control group. Pegaptanib proved to be efficacious and safe for the treatment of diabetic macular edema throughout the 12-month followup. To evaluate its long-term efficacy, further studies are required with larger numbers of patients and longer observational follow-up periods
