1Final anatomic and visual outcomes appear independent of duration of silicone oil intraocular tamponade in complex retinal detachment surgery显示文摘AIM: To report anatomic and visual outcomes following silicone oil removal in a cohort of patients with complex retinal detachment, to determine association between duration of tamponade and outcomes and to compare patients with oil removed and those with oil in situ in terms of demographic, surgical and visual factors. METHODS: We reported a four years retrospective case series of 143 patients with complex retinal detachments who underwent intraocular silicone oil tamponade. Analysis between anatomic and visual outcomes, baseline demographics, duration of tamponade and number of surgical procedures were carried out using Fisher's exact test and unpaired two-tailed t-test. RESULTS: One hundred and six patients(76.2%) had undergone silicone oil removal at the time of review with 96 patients(90.6%) showing retinal reattachment following oil removal. Duration of tamponade was not associated with final reattachment rate or with a deterioration in best corrected visual acuity(BCVA). Patients with oil removed had a significantly better baseline and final BCVA compared to those under oil tamponade(P=0.0001, <0.0001 respectively). CONCLUSION: Anatomic and visual outcomes in this cohort are in keeping with those reported in the literature. Favorable outcomes were seen with oil removal but duration of oil tamponade does not affect final attachment rate with modern surgical techniques and should be managed on a case by case basis.Maedbh Rhatigan Elizabeth Mc Elnea Patrick Murtagh Kirk Stephenson Elaine Harris Paul Connell David Keegan 2018International Journal of Ophthalmology(English edition)2018,11,1:7
2Paediatric retinal detachment:aetiology,characteristics and outcomes显示文摘AIM: To provide contemporary data on the aetiology, clinical features and outcomes of paediatric retinal detachment.METHODS: A retrospective review of all those under 16 y who underwent surgical repair for retinal detachment at a single centre between the years 2008 and 2015 inclusive was performed. In each case the cause of retinal detachment, the type of detachment, the presence or absence of macular involvement, the number and form of reparative surgeries undertaken, and the surgical outcome achieved was recorded.RESULTS: Twenty-eight eyes of 24 patients, 15(62.5%) of whom were male and 9(37.5%) of whom were female, their mean age being 11.6 y and range 2-16y developed retinal detachment over the eight year period studied. Trauma featured in the development of retinal detachment in 14(50.0%) cases. Retinal detachment was associated with other ocular and/or systemic conditions in 11(39.3%) cases. A mean of 3.0 procedures with a range of 1-9 procedures per patient were undertaken in the management of retinal detachment. Complex vitrectomy combined with scleral buckling or complex vitrectomy alone were those most frequently performed. Mean postoperative visual acuity was 1.2 log MAR with range 0.0-3.0 log MAR. In 22 of 26(84.6%) cases which underwent surgical repair the retina was attached at last follow-up.CONCLUSION: Aggressive management of paediatric retinal detachment including re-operation increases the likelihood of anatomical success. In cases where the retinal detachment can be repaired by an external approach alone there is a more favourable visual outcome.Elizabeth McElnea Kirk Stephenson Sarah Gilmore Michael O'Keefe David Keegan 2018International Journal of Ophthalmology(English edition)2018,11,2:2

8Surgical management of non-syndromic ectopia lentis显示文摘AIM:To compare whether aphakic contact lenses or secondary iris-claw intraocular lenses are superior in the refractive management post-pars plana vitreolensectomy in a pedigree with an FBN1 mutation causing non-syndromic ectopia lentis(NSEL)with retinal detachment(RD).METHODS:Eight affected individuals had pars plana vitreolensectomy for bilateral ectopia lentis(EL).Twelve eyes of 6 patients had secondary iris-claw intraocular lenses inserted and 4 eyes of 2 patients were managed with contact lenses.Rhegmatogenous retinal detachment(RRD)was treated when necessary.Pre-and post-operative assessment included visual acuity,endothelial cell count and dilated fundal examination.RESULTS:Macula-on RRD was present in all individuals>18 y,64%(7/11 eyes)presenting post-vitreolensectomy with 57%having bilateral non-synchronous RRD.Surgical aphakia was managed with iris-fixated intraocular lenses(IOL group,n=6),or contact lenses(CL group,n=2).Visual acuity≥0.3 log MAR(driving standard)was achieved in 75%of IOL group eyes and 25%of the CL group eyes.Mean loss of corneal endothelial cell count in the IOL group was 4%at 2 y post-operative.CONCLUSION:In this cohort,refractive management with iris-claw IOLs provided superior outcomes to contact lenses and the authors recommend this as the optimal refractive correction in EL patients.Kirk AJ Stephenson Michael O’Keefe David J Keegan 2020International Journal of Ophthalmology(English edition)2020,13,7:1
