Successful retinal reattachment was obtained in 28 eyes out of 30 (93.3%), and 2 eyes (6.7%) had recurrent RD. Best-corrected distance visual acuity (BCDVA) in logMAR was significantly improved from baseline 1.74 ± 0.05 to 0.93 ± 0.04, 0.82 ± 0.05, 0.80 ± 0.07, and 0.73 ± 0.055 at follow-up visits 3, 6, and 9 months and one year, respectively (

≤ 0.001). There were no serious ocular complications recorded.

The results of this study indicated that primary vitrectomy with simultaneous use of both C3F8 and short-term PFO as retinal tamponades was effective and safe in the management of complex cases of RRD with PVR grade C and inferior breaks. This trial is registered with NCT04168255.

To describe the epidemiology of ocular emergencies in children in a hospital-based emergency room (ER).

The medical reports of all children, 14 years of age and younger, who attended La Paz University Hospital (Madrid, Spain) ER from September 2015 to August 2016 were prospectively collected. Demographic data, origin, symptom for consultation, diagnostic tests, final diagnosis, and final referral of patients were recorded.

A total of 774 children were attended 57% boys and 43% girls. Mean age was 5 years (SD 4.10 years, range 0-14 years) without significant differences between sexes. Most children went to the ER because parents or teachers took the decision (75%), 24% were referred from the paediatric ER for evaluation, and 0.78% were referred from another hospital or by an out-clinic ophthalmologist. The reasons for consultation were red eyes (61%), traumatism (17%), referred from the paediatrician to have the fundus explored in children with headache (7%), eyelids problems (7%), and visual loss (7%). t is necessary to increase public awareness about the symptoms, the way of transmission, and treatment. Ocular trauma was also a common cause of presentation and the majority were contusional and mild. There is also a need for education of parents, teachers, and coaches regarding the potential for eye injuries. Ophthalmologists and paediatricians must take an active role in educating people about the prophylactic measures to prevent eye injuries in children.

Electronic medical records of patients evaluated in the Ophthalmic Genetics clinic at the National Eye Institute (NEI) between 2008 and 2018 were searched for a superficial ODD diagnosis. Color fundus and autofluorescence images were reviewed to confirm ODD, supplemented with optical coherence tomography (OCT) in uncertain cases when available. Demographic information, examination, and genetic testing were reviewed. Disc areas and disc-to-macula distance to disc diameter ratios (DM  DD) were calculated.

Fifty six of 6207 patients had photographically confirmed ODD (0.9%). Drusen were predominantly bilateral (66%), with a female (62%) and Caucasian (73%) predilection. ODD prevalence in our cohort of patients with inherited retinal degenerations was 2.5%, and ODD were more prevalent in the rod-cone dystrophy subgroup at 2.95% (OR = 3.3 [2.1-5.3],

< 0.001) compared to the ophthalmic genetics cohort. Usher patients were more likely to have ODD (10/132, 7.6%, OR = 9.0 [4.3-17.7],

< 0.001) and had s the rest of our ODD cohort (disc area P=0.001, DM  DD P=0.03). Discussion. While an association between ODD and retinitis pigmentosa has been reported, this study surveys a large cohort of patients with inherited eye conditions and finds the prevalence of superficial ODD is lower than that in the literature. Some subpopulations, such as rod-cone dystrophy and Usher syndrome, had a higher prevalence than the cohort as a whole.

The biomechanical properties of ecstatic cornea undergo changes. This study evaluates the biomechanical changes of ecstatic cornea after implantation of two types of intracorneal stromal ring (ICR).

For doing this prospective cross-sectional study, 32 patients with keratoconus (KCN) were randomly divided into two 16-member groups (group I MyoRing, group II KeraRing). The main inclusion criteria were transparent cornea with no scar in the central part, corneal thickness >450 

in the incision region, keratometry within 48-52 diopters, and progressive course of corneal thinning. Biomechanics of the cornea was evaluated by “ORA” and “Corvis” devices. All of the data were recorded and analyzed before implantation of the rings and 6 months thereafter.

The mean ages of patients of groups I and II were 26 ± 6.55 and 33.86 ± 8.5, respectively. The postoperative change of sphere refraction was significant in both groups. However, reduction in the astigmatism was significant only in group I. In addition, the change of flat meridian keratometry (Kf) was significant before and after ring implantation in group I, unlike group II. The changes in CH and CRF parameters (ORA) were not significant in either group before and after the operation. selleckchem Besides, only HRC parameter (Corvis) decreased significantly in both groups before and after the operation.

Both MyoRing and KeraRings have positive effects on the biomechanics of cornea at least during the first year after implantation. Comparison of these two types of ICR did not show significant differences in Corvis and ORA parameters.

Due to its wide distribution in endemic areas, Leishmania (V.) braziliensis is considered one of the most important species in circulation in Brazil. Molecular targets derived from ribosomal RNA (rRNA) were used in studies to identify Leishmania spp.; however, the Intergenic Spacer (IGS) region has not yet been explored in parasite species differentiation. Besides, there is a shortage of sequences deposited in public repositories for this region. Thus, it was proposed to analyze and provide sequences of the IGS rRNA region from different Leishmania spp. and to evaluate their potential as biomarkers to characterize L. braziliensis. A set of primers was designed for complete amplification of the IGS rRNA region of Leishmania spp. PCR products were submitted to Sanger sequencing. The sequences obtained were aligned and analyzed for size and similarity, as well as deposited in GenBank. Characteristics of the repetitive elements (IGSRE) present in the IGS rRNA were also verified.
