Via pars plana anterior iris enclavation IOL fixation

AIM: To describe a via pars plana anterior iris enclavation intraocular lens (IOL) fixation technique METHODS: A total of 35 consecutive aphakic vitrectomised patients (average age 71.12±10.12y) underwent pars plana vitrectomy (PPV) and via pars plana anterior iris enclavation IOL fixation. RESULTS: The mean preoperative best corrected visual acuity (BCVA) was 0.11±0.14 logMAR, the mean postoperative BCVA was 0.07±0.11 logMAR. The preoperative mean spherical equivalent was 7.22±4.21 D. The final mean spherical equivalent was -0.25±0.15 D. No eyes had hypotony, retinal or choroidal detachment or endophthalmitis. CONCLUSION: This technique may be a safe and useful in the case of aphakia, and a prospective study would be useful to confirm this findings.

AIM: To evaluate the effect of vitrectomy combined with scleral shortening for eyes with myopic macular retinoschisis. METHODS: Thirty-seven patients with myopic macular retinoschisis who underwent pars plana vitrectomy (PPV) combined with scleral shortening were reviewed. Axial length (AL), the height of macular retinoschisis, the height of retinal detachment if existed, the diameter of macular hole if existed and best corrected visual acuity (BCVA) were obtained. The preoperative and postoperative parameters were compared. RESULTS: At postoperative 24mo, the mean AL and height of macular retinoschisis were reduced significantly by 0.79 mm and 256.51 μm (t=8.064, P<0.0001; Z=-5.086, P<0.0001) respectively. In addition, the mean height of retinal detachment and diameter of macular hole were also reduced significantly by 365.38 μm and 183.68 μm (Z=-4.457, P=0.000008; Z=-2.983, P=0.003) respectively. Meanwhile, the postoperative BCVA was improved markedly (Z=-2.126, P=0.033). CONCLUSION: Vitrectomy combined with scleral shortening is an effective surgical method for eyes with myopic macular retinoschisis, whether or not macular hole and retinal detachment are present.

Purpose. To compare the visual outcomes and complications of patients who underwent flanged transconjunctival sutureless intrascleral intraocular lens (SIS IOL) implantation after anterior and pars plana vitrectomy. Methods. All patients who underwent flanged transconjunctival SIS IOL fixation using a 27-gauge needle between September 2017 and November 2019 and were followed up for at least six months were evaluated. The cases in which anterior vitrectomy was performed were classified as Group 1, and those that underwent pars plana vitrectomy were classified as Group 2. The best-corrected visual acuity (BCVA), spherical equivalent values, corneal endothelial cell density, and intraocular pressures were compared between the two groups before and after the operation. Intraoperative and postoperative complications were assessed. Results. The study included 108 eyes of 108 patients who were included in the study. Group 1 consisted of 48 patients and Group 2 comprised of 60 patients. When the findings between Groups 1 and 2 were compared in the postoperative period, there was no statistically significant difference in terms of the mean intraocular pressure increase, endothelial cell density, BCVA, and spherical equivalent value ( P = 0.818 , 0.601, 0.368, and 0.675, respectively). When all the patients were considered as a single group, the mean spherical value at the sixth postoperative month was 0.3 ± 2.2 D (min-max, (−5.5)–(+6)), the mean cylindrical value was −1.7 ± 2.4 D (min-max, (−9.25)–(+4)), and the mean spherical equivalent value was −0.5 ± 2.3 D (min-max, (−6.5)–(+6)). Conclusion. The flanged transconjunctival SIS IOL fixation technique performed using a 27-gauge needle is safe and effective in the patient group with aphakia and lens/IOL dislocation or subluxation. However, in patients planned to undergo flanged transconjunctival SIS IOL implantation, pars plana vitrectomy seems to be a more suitable option than anterior vitrectomy to reduce complications.

We evaluated the effect of intravitreal bevacizumab (IVB) injection before pars plana vitrectomy (PPV) on intravitreal hemorrhage (VH) during and after vitrectomy for postoperative the first day and the first month in pseudophakic patients with proliferative diabetic retinopathy (PDR). This retrospective study was performed on 44 eyes of 44 patients who underwent vitrectomy for PDR. Patients were divided into PPV (n = 22 eyes) and PPV + IVB (n = 22 eyes) groups. Injection of bevacizumab (1.25 mg/0.05 mL) was performed 3 days before vitrectomy. Outcomes of visual acuity as well as intraoperative and postoperative VH were compared between the two groups. One month after surgery, visual acuity improved in PPV and PPV + IVB groups ( P = 0.005, P = 0.006), respectively. There was no difference between the two groups in best corrected visual acuity at baseline and after vitrectomy ( P = 0.71). Intraoperative bleeding into the vitreous was recorded in 14 (63.6%) cases in the PPV group and in 7 (31.8%) cases in the PPV + IVB group. The first month, intravitreal hemorrhage was recorded in six patients in the PPV group and in two patients in the PPV + IVB group ( P = 0.03). The mean pre-postoperative central macular thickness was similar in both groups. Intravitreal injection of IVB before vitrectomy decreased the rate of VH at the time of surgery and at the first postoperative month in patients with PDR.

AbstractThis study aimed to compare the surgical outcomes of pars plana vitrectomy (PPV) with and without air tamponade in patients with idiopathic epiretinal membrane (iERM). We prospectively enrolled 145 patients with iERM who underwent a 25-gauge transconjunctival sutureless PPV. Patients were assigned to either the air tamponade (air) group (79 eyes) or balanced salt solution (BSS; no tamponade) group (66 eyes). The central macular thickness (CMT), peripapillary retinal nerve fiber layer (pRNFL) thickness, and best-corrected visual acuity (BCVA) were compared for two years. At baseline, there were no significant differences between the two groups. CMT and BCVA were not significantly different between the groups for 2 years. However, the air group had a significantly lower thickness in the superior temporal pRNFL sector at 1 month (p = 0.01) and in the inferior temporal and superior temporal pRNFL sectors at 3 months (p = 0.02 for both). There were no significant differences between both groups in all the pRNFL sectors from 6 months to 2 years. The outcomes of PPV with air tamponade and that with no tamponade appear to be equivalent. This shows that air tamponade may not be an imperative procedure for iERM surgery and has no additional benefit.

Clinical Records

AbstractWe evaluated predictive factors for visual outcomes in patients with idiopathic epiretinal membrane (iERM) after pars plana vitrectomy (PPV). Clinical records for 114 eyes (114 patients, mean age: 70.6 years) with iERM treated by PPV between March 2012 and March 2018 were retrospectively reviewed. Overall, the mean postoperative best-corrected visual acuity (BCVA) and central retinal thickness measured by optical coherence tomography improved as early as 1 month after surgery, and further improved until 3 months (P < 0.01). Multiple linear regression analyses adjusted for the preoperative BCVA showed that older age (B, 0.010; 95% confidence interval, 0.003 to 0.016; P = 0.003) and a shorter axial length (AL; B, −0.059; 95% confidence interval, −0.099 to −0.019; P = 0.005) predicted worse postoperative BCVA. The Mann-Whitney U test showed that the postoperative BCVA was worse in eyes with AL < 23.6 mm than in eyes with AL ≥ 23.6 mm (P = 0.037), and in patients aged ≥69 years than in patients aged <69 years (P = 0.024). The findings may help in evaluating surgical indications for each patient to obtain satisfactory outcomes, irrespective of the preoperative BCVA.

Purpose: It was the aim of this study to determine the efficacy of intravitreal ranibizumab as treatment of choroidal neovascularizations associated with pathologic myopia. Materials and Methods: In an uncontrolled, prospective time series cohort study, 65 eyes of 64 consecutive patients with choroidal neovascularization associated with pathologic myopia were treated with intravitreal ranibizumab and observed over 12 months. The change in best-corrected visual acuity (BCVA) at 6 and 12 months served as primary end point. Safety, central retinal thickness, neovascularization activity on fluorescein angiography and the number of ranibizumab injections were secondary end points. Results: BCVA improved significantly throughout the follow-up (p = 0.001). The mean BCVA was 0.2 at baseline (SD 0.13) and 0.4 at 12 months (SD 0.21). Improvement was strongest within the first 3 months (p = 0.0001). The mean central retinal thickness showed a reduction from 313 μm (SD 82) to 243.5 μm (SD 31; p = 0.0001). Conclusion: Intravitreal ranibizumab offers a safe and effective treatment for choroidal neovascularizations in pathologic myopia.

Purpose: The purpose of this report was to present our findings in 4 cases of rhegmatogenous retinal detachment (RRD) that recurred 10, 11, 12, and 17 years after a reattachment surgery by pars plana vitrectomy (PPV). Methods: Four cases of a recurrent RRD had undergone scleral buckling surgery and vitrectomy. Patients: The recurrence of the RRD was observed 10–17 years after the successful attachment by PPV. The macula was detached in all cases, and none of the eyes had severe proliferative vitreoretinopathy. The cause of the recurrence was a new retinal break in 3 eyes and a reopening of an old retinal break in the other eye. The new breaks had a punched-out shape and had neither a horseshoe tear nor an atrophic hole associated with lattice degeneration. PPV combined with scleral buckling was performed, and a reattachment was achieved in all cases. The best-corrected visual acuity (BCVA) at the last visit ranged from 20/30 to 20/25, but the BCVA in 1 eye was 20/200 because of amblyopia. Conclusions: We experienced 4 rare cases of a recurrent retinal detachment 10–17 years after the primary RRD. PPV and scleral buckling were effective and the anatomical and the functional outcomes were good.

Purpose: To investigate the outcomes of re-fixation after the first intraocular lens (IOL) scleral fixation. Methods: We retrospectively reviewed the charts of patients who underwent second IOL scleral fixation and vitrectomy for dislocation of IOL after the first IOL scleral fixation. We compared the best-corrected visual acuity (BCVA) and spherical equivalent (SE) after 1 month of the first and second surgery, and noted the complications. Results: We included 21 eyes that underwent second IOL scleral fixation: 13 eyes (61.9%) with IOL exchange and eight (38.1%) with one-haptic fixation. Mean BCVAs (LogMAR) were 0.17 ± 0.25 and 0.11 ± 0.23 after the first and second surgery, respectively (p = 0.073); mean SEs were -0.94 ± 1.69 and -0.58 ± 1.46 diopters after the first and second surgery, respectively (p = 0.076). Postoperative complications occurred in eight eyes (38.1%), including temporarily increased intraocular pressure and suture knots exposure. However, none of the complications required re-operation. Conclusions: The outcomes of primary and secondary IOL fixation were similar, and there were no serious complications of the second surgery.
