AIM: To assess the efficacy and safety of a heavy silicone oil(Densiron 68) in the management of inferior retinal detachment ***: A retrospective non-comparative consecutive case series study. Forty-nine cases of complex inferior retinal detachment were treated using Densiron 68 heavy silicone oil(HSO) as the endotamponade. Our main purpose was anatomic reattachment following Densiron 68 removal. Functional outcomes, rate of recurrences, the presence of inflammatory complications and intraocular pressure alterations were evaluated. RESULTS: Forty-nine patients affected by complex retinal re-detachment were recruited. The mean follow-up was 7.6(±1.5) mo. The mean best corrected visual acuity after Densiron 68 removal was 0.95 log MAR, standard error(SE: 0.068). Retinal reattachment was 61.2% after first surgery and 81.6% after second surgery. Nineteen cases(38.8%) had recurrences when intraocular heavy silicon oil was in situ, 26.3%(5 cases) of which involved the inferior retina. CONCLUSION: Densiron 68 efficiently fills the inferior retinal periphery and might lower the risk of inferior proliferative vitreoretinopathy development, in particular after a standard silicon oil tamponade that reduces the proliferative process in the upper quadrants of the retina.

This retrospective non-comparative consecutive case series study was conducted at Azienda Ospedaliera Universitaria Careggi, Florence, Italy and describes a useful intraocular lens(IOL) repositioning technique using iris sutures. In our study, 41 consecutive cases of posteriorly dislocated IOLs were surgically treated between January 2015 and May 2017. Six of the cases were post-traumatic luxations, and 20 patients had pseudoexfoliation syndrome. All the patients underwent pars plana vitrectomy and same IOL repositioning using iris sutures. The mean followup was 12.2 mo. The mean preoperative best corrected visual acuity(BCVA) was 0.10±0.15 logMAR, whereas the mean postoperative BCVA was 0.08±0.14 logMAR. The mean postoperative BCVA did not change significantly from the preoperative BCVA. The final mean spherical equivalent was-0.44±0.49 SD. Three lenses(7.31%) were found tilted during post-operative follow-up. Two eyes(4.87%) had postoperative cystoid macular edema. No eyes had endophthalmitis, hypotony, retinal or choroidal detachment. The iris fixation technique seems to be a safe and valid option for the management of dislocated IOLs.

Synthetic dyes are recalcitrant to degradation and toxic to different organisms. Physical-chemical treatments of textile wastewaters are not sustainable in terms of costs. Biological treatments can be more convenient and the lig-nin-degrading extracellular enzymatic battery of basidiomycetes are capable to discolor synthetic dyes. Many basidi-omycetes are edible mushrooms whose industrial production generates significant amount of spent mushroom substrate (SMS) with residual high levels of lignin-degrading extracellular enzymatic activities. We have demon-strated that the low cost organic substrate, the SMS deriving from the cultivation of the basidiomycetes Pleurotus ostreatus, is able to discolor anthraquinonic, diazo and monoazo-dyes when incubated in dying chromo-reactive and chromo-acid baths containing surfactants and anti-foams, where the concentrations of the different dyes are exceeding the one recovered in the corresponding wastewaters. Laccase was the lignin-degrading extracellular enzyme involved in the discolouring process. The exploitation of the low cost SMS in the treatment of textile wastewaters is proposed. Accordingly, a toxicological assessment, based on a cyto-toxicity test on a human amnion epithelial cell line (WISH) and the estimation of the germination index (GI%) of Lactuca sativa, Cucumis sativus and Sorghum bicolor, has been performed, showing the loss of toxicity of the chromo-baths after being discoloured by the SMS.
