Project description:The current technique for implanting flangedintraocular lens (IOL) suffers from complications like haptic exposure and tilting of the implanted IOL. We describe a modification of the currently described technique to obviate its shortcomings. Five eyes of five patients with a minimum of 1 year of follow-up were included. In this technique, two scleral pockets were made nasal and temporal to embed the flanged haptics. The primary outcome measure was the improvement in visual acuity (VA) postoperatively and the secondary outcome measures were postoperative complications. The primary objective of this current modification is to simplify the surgical technique for secondary IOL implantation and make it more replicable and predictive. The mean age of the patients was 19.44 years. The mean preoperative VA was 0.44 logMAR which improved to 0.26 logMAR at the 6-week postoperative visit. The mean follow-up was 496+/- 80 days. The maximum follow-up was 647 days. There were no postoperative complications such as haptic exposure, hypotony, or IOL tilt in any cases. The new E-flanged IOL technique has good visual outcomes and does not have postoperative complications. It has less intraoperative manipulation and complications.

Project description:We implanted posterior chamber intra ocular lenses (PC IOL) in 107 eyes with posterior capsular breaks. Left over posterior capsular frill at the periphery was used to hold and support the PC IOL. After a median follow up of 2.5 years, 96.9% of the patients who developed per operative posterior capsular break and 67.56% who had pre-existing capsular breaks achieved 6/12 or better visual acuity. Remaining 32.44% of the patients with pre-existing capsular break due to previous surgical intervention or trauma achieved 6/18 or worse visual acuity.

Project description:PurposeTo evaluate clinical outcomes with a premium diffractive-refractive trifocal toric intraocular lens (IOL) over a 12-month period.MethodsMulticentre prospective clinical trial including 227 eyes of 114 patients undergoing cataract surgery with bilateral implantation of the AT LISA tri toric 939MP IOL (Carl Zeiss Meditec, Jena, Germany). One patient was implanted unilaterally. Outcome measures were: visual acuity, manifest refraction, reading performance, contrast sensitivity, defocus curve, patient satisfaction and subjective quality of vision. Alpins vector analysis was used to evaluate astigmatic changes.Results12-month follow up results of binocular uncorrected distance, intermediate and near visual acuity were ?0.3?logMAR in 99.0%, 98.10% and 91.40% of eyes, respectively. 79.7% of eyes had a cylinder value of ±0.50?D at 12 months post-surgery. Contrast sensitivity was in the normal range at 6 months post-surgery. The defocus curve exhibited a smooth transition between far and near foci. Vector analysis showed a mean magnitude of error of -0.16?±?0.48?D. Mean binocular distance-corrected reading visual acuity was 0.15?±?0.13?logRAD at 6 months postoperatively. 93.3%, 89.4% and 84.6% of patients expressed satisfaction (good or very good) with distance, intermediate and near vision, respectively, 12 months after surgery. Most (?95%) patients felt that visual disturbances, including halos, glare, focusing difficulties and depth perception, caused little or no disturbance.ConclusionsThe diffractive-refractive trifocal toric IOL, AT LISA tri toric 939MP, provides effective distance, intermediate and near visual acuity in eyes with corneal astigmatism. Patient satisfaction was high and 98.1% of patients expressed satisfaction with the IOL implanted.

Project description:To analyse the benefit of cochlear implantation in young deaf children with Waardenburg syndrome (WS) compared to a reference group of young deaf children without additional disabilities.A retrospective study was conducted on children with WS who underwent cochlear implantation at the age of 2 years or younger. The post-operative results for speech perception (phonetically balanced standard Dutch consonant-vocal-consonant word lists) and language comprehension (the Reynell Developmental Language Scales, RDLS), expressed as a language quotient (LQ), were compared between the WS group and the reference group by using multiple linear regression analysis.A total of 14 children were diagnosed with WS, and 6 of them had additional disabilities. The WS children were implanted at a mean age of 1.6 years and the 48 children of the reference group at a mean age of 1.3 years. The WS children had a mean phoneme score of 80% and a mean LQ of 0.74 at 3 years post-implantation, and these results were comparable to those of the reference group. Only the factor additional disabilities had a significant negative influence on auditory perception and language comprehension.Children with WS performed similarly to the reference group in the present study, and these outcomes are in line with the previous literature. Although good counselling about additional disabilities concomitant to the syndrome is relevant, cochlear implantation is a good rehabilitation method for children with WS.

Project description:BACKGROUND:Coronavirus disease 2019 (COVID-19) is a pandemic first originated in Wuhan the capital of Hubei province, China in December 2019 and then spread globally. It is caused by SARS-CoV-2. Until 1st April 2020, the number of cases worldwide was recorded to be 823,626 with 40,598 deaths. Most of the reported cases were adults with few cases described in children and neonates. OBJECTIVES:We performed a systematic review and meta-analysis to analyse the disease characterisation in paediatric age group including the possibility of vertical transmission to the neonates. METHODS:Articles published up to 2nd April 2020 in PubMed and google Scholar were considered for this study. FINDINGS:The most frequently reported symptoms were cough 49% (95% CI: 42 - 55%) and fever 47% (95% CI: 41- 53%). Lymphopenia and increased Procalcitonin were recorded in (21%, 95% CI: 12 - 30%) and (28%, 95% CI: 18 - 37%) respectively. No sex difference for COVID-19 was found in paediatric age group (p?=?0.7). Case fatality rate was 0%. Four out of 58 neonates (6.8%) born to COVID-19 confirmed mothers tested positive for the disease. CONCLUSION:The disease trajectory in Paediatric patients has good prognosis compared to adults. Intensive care unit and death are rare. Vertical transmission and virus shedding in breast milk are yet to be established.

Project description:PURPOSE: To evaluate the visual acuity and quality-related satisfaction of patients implanted with a refractive design multifocal intraocular lens (IOL), and evaluate the factors predicting it including angle kappa. SETTING: Dr Agarwal's Eye Hospital and Eye Research Centre, Chennai. METHODS: In this prospective trial, 50 eyes of 44 consecutive patients were included. All patients underwent phacoemulsification with multifocal IOL implantation (Rezoom IOL, Abbott Medical Optics). The preoperative and postoperative assessment included slit lamp biomicroscopy, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA) and kappa angle assessment. At 1 year, 37 patients (43 eyes), who finished follow-up, were asked to rate their symptoms on a graded questionnaire (0-5 for five queries). RESULTS: The decimal scores for UCVA and BCVA were 0.38±0.21 and 0.47±0.17 (preoperative), and 0.75±0.22 and 0.99±0.11 (postoperative), respectively. Symptom scores were haloes 0.98±1.7, glare 0.69±1.48, blurred distance 1.0±1.7, intermediate 1.34±1.6, near 1.06±1.8. On regression analysis haloes depended on angle kappa and distance UCVA (R (2)=0.26, P=0.029), and glare on angle kappa (R (2)=0.26, P=0.033). Poor satisfactions with distance, intermediate, and near vision were linked with distance UCVA (R (2)=0.17, P=2.3 × 10(-4)), distance UCVA (R (2)=0.1, P=0.04), and near UCVA (R (2)=0.12, P=0.03), respectively. The strongest predictor, however, for overall visual discomfort was distance UCVA (R (2)=0.1, P=0.04). CONCLUSIONS: Our study suggests that there may be a role of misalignment between the visual and pupillary axis (angle kappa) in the occurrence of photic phenomenon after refractive multifocal IOL implantation.

Project description:IntroductionWith the current coronavirus disease 2019 (COVID-19) pandemic, concerns have been raised about the risk to children with inflammatory bowel diseases (IBD). We aimed to collate global experience and provide provisional guidance for managing paediatric IBD (PIBD) in the era of COVID-19.MethodsAn electronic reporting system of children with IBD infected with SARS-CoV-2 has been circulated among 102 PIBD centres affiliated with the Porto and Interest-group of ESPGHAN. A survey has been completed by major PIBD centres in China and South-Korea to explore management during the pandemic. A third survey collected current practice of PIBD treatment. Finally, guidance points for practice have been formulated and voted upon by 37 PIBD authors and Porto group members.ResultsEight PIBD children had COVID-19 globally, all with mild infection without needing hospitalization despite treatment with immunomodulators and/or biologics. No cases have been reported in China and South Korea but biologic treatment has been delayed in 79 children, of whom 17 (22%) had exacerbation of their IBD. Among the Porto group members, face-to-face appointments were often replaced by remote consultations but almost all did not change current IBD treatment. Ten guidance points for clinicians caring for PIBD patients in epidemic areas have been endorsed with consensus rate of 92% to 100%.ConclusionsPreliminary data for PIBD patients during COVID-19 outbreak are reassuring. Standard IBD treatments including biologics should continue at present through the pandemic, especially in children who generally have more severe IBD course on one hand, and milder SARS-CoV-2 infection on the other.

Project description:PURPOSE: To compare the visual outcomes between PRK-MMC and phakic IOL in patients with more than 8 diopter (D) of myopia. METHODS: This comparative study was performed on 23 eyes under treatment with Artiflex (group A) and 23 eyes under treatment with PRK-MMC (group B). Artiflex phakic IOL (Ophtec BV) was used in group A, and the VISX STAR S4 Excimer Laser (Abbott) was used for PRK-MMC in group B. RESULTS: The safety index was 1.11 ± 0.23 and 1.05 ± 0.25 (P = 0.100) and the efficacy index was 1.02 ± 0.11 and 0.98 ± 0.10 (P = 0.266) in group A and B, respectively. At 1 year after surgery, the manifest refraction spherical equivalent was -0.17 ± 1.18 and -0.25 ± 0.18 D in group A and B, respectively (P = 0.471). Mesopic CS showed no significant difference between the two groups in any spatial frequency. Total coma was 0.24 ± 0.17 and 0.67 ± 0.40 μm (P < 0.001), spherical aberration was -0.11 ± 0.11 and 0.41 ± 0.18 μm (P < 0.001), and RMS HOAT was 0.50 ± 0.20 and 0.96 ± 0.45 μm (P<0.001) in group A and B, respectively. CONCLUSION: Phakic IOL implantation was better than PRK-MMC in the correction of high myopia in terms of visual quality, but the two methods had no difference with regard to visual acuity. Therefore, PRK-MMC can be used when the anterior chamber depth is a limiting factor in the implantation of phakic IOLs.

Project description:PurposeTo compare the results of silicone and polypropylene Ahmed glaucoma valves (AGV) implanted during the first 10 years of life.MethodsA prospective study was performed on 50 eyes of 33 patients with paediatric glaucoma. Eyes were matched to either polypropylene or silicone AGV. In eyes with bilateral glaucoma, one eye was implanted with polypropylene and the other eye was implanted with silicone AGV.ResultsFifty eyes of 33 children were reviewed. Twenty five eyes received a polypropylene valve, and 25 eyes received a silicone valve. Eyes implanted with silicone valves achieved a significantly lower intraocular pressure (IOP) compared with the polypropylene group at 6 months, 1 year, and 2 years postoperatively. The average survival time was significantly longer (P=0.001 by the log-rank test) for the silicone group than for the polypropylene group and the cumulative probability of survival by the log-rank test at the end of the second year was 80% (SE: 8.0, 95% confidence interval (CI): 64-96%) in the silicone group and 56% (SE: 9.8, 95% CI: 40-90%) in the polypropylene group. The difference in the number of postoperative interventions and complications between both groups was statistically insignificant.ConclusionSilicone AGVs can achieve better IOP control, and longer survival with less antiglaucoma drops compared with polypropylene valves in children younger than 10 years.
