AIMTo evaluate the clinical findings of toxic keratopathy associated with abuse of topical anesthetics and the treatment efficacy of amniotic membrane transplantation (AMT).METHODSFifteen eyes of 10 patients with abuse of topical anesthetics were included in this study. The data collected included patients' demographic information, initial best corrected visual acuity (BCVA), clinical findings, time to AMT, duration of epithelization, additional treatments, posttreatment BCVA, and the results of psychiatric *** patients were male, with the mean age of 37.9±5.4y. The patients had received 0.5% proparacaine hydrochloride due to pain resulting from foreign bodies, such as welding flash burns and car battery explosions, for a mean of 18.2±12.4d. The mean initial BCVA of the patients was 0.069±0.100. All patients had persistent epithelial defects, stromal infiltration, ring ulcer, and corneal edema. Initially, medical treatment was attempted in all cases. Because of severe pain, persistent epithelial defects and progressing stromal thinning did not improve with medical treatment, thus, the patients underwent AMT. The mean posttreatment BCVA of the patients was 0.33±0.27. All of them, except for two patients, showed improved visual acuity. One patient underwent evisceration for corneal melting and endophthalmitis in another center, and one patient underwent evisceration for severe pain of unknown origin. All 5 patients who consented to a psychiatric examination had depression, had personality disorder, and used *** appears to be an effective method for pain relief, rapid epithelial and stromal healing; however, visual prognosis is still poor despite medical and surgical interventions.

Effects of astaxanthin on antioxidant parameters in ARPE-19 cells on oxidative stress model

International Journal of Ophthalmology(English edition) 2019年第6期12卷 930-935页

AIM: To observe the protective effect of astaxanthin(AST) against hydroquinone(HQ) mediated cell death in the apoptotic cascade and evaluate intracellular Ca2+ release, caspase-3, and-9 activation, reactive oxygen species(ROS) production in ARPE-19 ***: We cultured ARPE-19 cells in special mediums and performed MTT tests to determine protective effect of AST, before exposing the cells to HQ in an incubator. We analyzed intracellular Ca2+ release experiments, mitochondrial membrane depolarization, glutathione(GSH), glutathione peroxidase(GSH-Px) and ROS experiments, and apoptosis ***: ROS production ranges depend on the amount of cell death. We computed the correlation between ROS ranges and cell death by 20,70-dichlorofluorescein fluorescence, and Ca2+ levels by Fura-2-AM. HQ-induced cell death found out to rise ranges of caspase-3 and-9, and mitochondrial depolarization. These three steps were delayed by AST ***: ARPE-19 cells are avoided from HQinduced ROS production and caspase-3 and-9 activation by AST. AST may limit the range of caspase synthesis, Ca2+ release and excess production of ROS with antiapoptotic effect. This study proposes a new therapeutic approach for the treatment of age-related macular degeneration.

AIM： To investigate whether single-dose intravitreal injections of bevacizumab and ranibizumab transfer into milk. METHODS： This study included lactating 12 sheep and a single 3-month old suckling lamb of each sheep. Two groups consisting of 6 sheep and their lambs were constituted; the ranibizumab group and the bevacizumab group before the administration of intravitreal injections, blood and milk samples were obtained from all sheep and, following the injections, blood and milk samples of all sheep and blood samples of all lambs were collected at regular time points. Serum and milk concentrations of bevacizumab and ranibizumab were measured using an enzyme-linked immunosorbent assay（ELISA） kit. The limit of determination was 0.9 ng/m L for bevacizumab and 0.62 ng/m L for ***： At 6h after intravitreal injections, bevacizumab concentration was above the limit of determination in the blood of all sheep. At 3wk, when the study was terminated, bevacizumab concentrations were high in 4 sheep. Even though bevacizumab concentrations in milk showed fluctuations, the drug transferred into the milk of all sheep at detectable concentrations. Ranibizumab drug concentrations in the blood and milk of sheep and those in the blood of lambs were below the limit of determination by the ELISA ***： This sheep model study demonstrate that intravitreal injection of ranibizumab, which did not transfer into the milk of sheep and suckling lambs, is safer than bevacizumab during lactation period.

Eucalypt-feeding psyllids, Glycaspis brimblecombei Moore （Hemiptera： Psylloidea： Aphalaridae）, native to the Australian region, has emerged as an aggressive pest on Eucalyptus in many countries as it was described recently in Greece and Turkey. This study aimed to report this invasive species and its parasitoids on Eucalyptus growing area in Northern Cyprus. G. brimblecombei infested leaves were collected and brought to the laboratory for identification and collection of parasitoids emerged from the pest. In this paper, presence of G. brimblecombei and the parasitoid of the red gum lerp psyllid Psyllaephagus bliteus Riek （Hymenoptera： Encyrtidae） were reported for the first time in Northern Cyprus. Detailed information about the pest and its parasitoids were discussed.
