Assessment of reporting quality of meta-analyses of randomized controlled trials in neovascular age-related macular degeneration published from April 2014 to May 2018 using prisma statement.

PURPOSE: To evaluate the reporting quality of meta-analysis on neovascular age-related macular degeneration treatment and safety profile based on PRISMA statement. METHODS: Electronic search performed in August 2018 to retrieve meta-analyses published from April 2014 to May 2018. PRISMA evaluation was determined by total scores of individual meta-analyses and items scores. Statistical analysis of parameters affecting the reporting evaluation included subgroup multivariate analysis and regression analysis. RESULTS: Twelve meta-analyses were finally included, three being Cochrane systematic reviews. Mean PRISMA score is 23.2/27 (86.1%). Eleven PRISMA ITEMS had significantly higher %score in 12 meta-analyses than in nine non-Cochrane meta-analyses measurements. Positive strong correlation identified between PRISMA %score and journal impact factor (JIF). Multivariate analysis between high-scored and low-scored meta-analyses established difference in means of several parameters (JIF, Publication Year). CONCLUSIONS: The evaluation of overall reporting quality was favorable. As expected, the key role of several characteristics of meta-analysis affects this quality. Under-reporting of specific items (protocol, search strategy and assessment of risk of bias) indicates the urgency for PRISMA compliance.

Inter- and intraobserver repeatability and reproducibility of choroidal thickness measurements using two different methods.

PURPOSE: To measure the inter- and intraobserver repeatability and reproducibility of choroidal thickness measurements taken by the enhanced depth imaging of spectral-domain optical coherence tomography (EDI-OCT) in randomly selected subjects using two different protocols. METHODS: Twenty subjects of the Thessaloniki Eye Study database were randomly selected. The participants underwent EDI-OCT, and the choroidal thickness was measured on EDI images using two different protocols. All images were assessed by two examiners independently in two sessions in different days. RESULTS: The interobserver intraclass correlation coefficient (ICC) for average choroidal thickness was 0.944. The average ICC for central, Cmin, and Cmax choroidal thickness was 0.899, 0.863, and 0.955, respectively. The interobserver ICC for average choroidal volume was 0.932. Intraobserver repeatability ICC for grader 1 ranged between 0.925 and 0.9720 and for grader 2 between 0.913 and 0.994. CONCLUSION: Choroidal thickness measurements by EDI-OCT showed a high inter- and intraobserver reproducibility.

Twelve-Year Incidence of Open-angle Glaucoma: The Thessaloniki Eye Study.

OBJECTIVE: The objective of this study was to determine the 12-year incidence of open-angle glaucoma (OAG), with further classification into primary open-angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG), in an elderly White population. DESIGN: A longitudinal, population-based study in urban Northern Greece. PARTICIPANT: Surviving cohort of the 2554 Thessaloniki Eye Study subjects 60 years and above who had the baseline examination. METHODS: The surviving cohort was re-examined 12 years after baseline, using the same methodology and the same standard operating procedures as in the baseline examination. The definitions of glaucoma and pseudoexfoliation were consistent throughout the study. The 12-year incidences of OAG, POAG, and PEXG with corresponding 95% confidence intervals (CIs) were calculated for the whole study population, consisting of clinic-visit and home-visit participants. The population at risk was defined as those who did not meet the study criteria for the diagnosis of glaucoma in either eye at baseline. MAIN OUTCOME MEASURES: Twelve-year incidence of OAG, with further classification into POAG and PEXG. RESULTS: Of 1468 eligible subjects in the surviving cohort, 1092 were examined (participation rate 74%). Mean age at baseline was 68.9±4.6 years. Mean follow-up time was 11.6±1.6 years. The 12-year incidence of OAG was 4.4% (95% CI: 3.3-5.8); 0.37% per year. In the overall population the incidence of POAG and PEXG was 2.1% (95% CI: 1.3-3.2) and 2.3% (95% CI: 1.5-3.4), respectively. The corresponding incidence proportions were 2.9 (95% CI: 1.8-4.3) in those without PEX and 8.9 (95% CI: 5.8-12.9) in those with PEX at baseline and/or incidence. The latter was strongly associated with higher odds for incident glaucoma (odds ratio=3.34, 95% CI: 1.83-6.08, P<0.001). Of all incident OAG cases, 11.1% (95% CI: 4.4-24) had baseline intraocular pressure >21 mm Hg. CONCLUSIONS: The incidence of OAG was similar or higher compared with other White populations. The incidence of glaucoma in those with PEX was higher compared with the incidence of glaucoma in those without PEX.

Bilateral Herpes Simplex Virus-related Peripheral Ulcerative Keratitis Leading to Corneal Perforation in a Patient with Primary Herpes Simplex Virus Infection.

PURPOSE: To present a case of bilateral peripheral ulcerative keratitis (PUK) caused by primary herpes simplex virus-1 (HSV-1) infection resulting in corneal perforation. CASE REPORT: A 24-year-old man presented at the eye casualty of our clinic, with a 20-day history of severe pain, redness, photophobia, and tearing in both of his eyes. Slit-lamp examination revealed bilateral superior corneal perforation. A laboratory work-up that included immunological testing for infectious and autoimmune factors showed primary HSV infection. Positive PCR analysis of corneal scrapings for HSV confirmed initial end-organ ocular infection. Because the patient showed progressive HSV-1-related PUK resulting in bilateral superior corneal perforation with iris prolapse, he was prescribed both systemic and topical acyclovir and prednisone. He then underwent bilateral surgical intervention, namely eccentric penetrating keratoplasty in one eye and a two step procedure in the other, whereby two corneal patch grafts and an amniotic membrane transplant were initially used, followed 1 month later by a large diameter penetrating keratoplasty. CONCLUSION: In cases of PUK, differential diagnosis should include infectious and autoimmune diseases. Primary HSV should also be considered as a potential cause of this form of keratitis, which, if left untreated, can lead to devastating outcomes. To our knowledge, this is the first published case of bilateral PUK caused by primary HSV-1 infection.

The omega-3 and retinopathy of prematurity relationship.

The aim of this article is to examine the effect of omega-3 (ω-3) long-chain polyunsaturated fatty acids (LCPUFAs) intake on retinopathy of prematurity (ROP) by reviewing the experimental and clinical trials conducted on animal models and infants. LCPUFAs demonstrate cytoprotective and cytotherapeutic actions contributing to a number of anti-angiogenic and neuroprotective mechanisms within the retina. Their intake appears to have a beneficial effect on ischemia, oxidative stress, inflammation and cellular signaling mechanisms, influencing retinal cell gene expression and cellular differentiation. ω-3 LCPUFAs may modulate metabolic processes that activate molecules implicated in the pathogenesis of vasoproliferative and neurodegenerative retinal diseases such as ROP.
