PurposeTo assess the outcomes of the non-valved Aurolab aqueous drainage implant (AADI) in neovascular glaucoma (NVG).MethodsData of consecutive patients with NVG who underwent AADI and had a minimum follow-up of 2 years were included. The primary outcome measure was the cumulative rate of surgical failure defined as intraocular pressure (IOP) >21 mm Hg or reduced <20% below baseline, IOP ≤5 mm Hg, reoperation for glaucoma or a complication, or loss of light perception vision.ResultsWe included 85 eyes of 85 patients with NVG, with a mean age of 61.2±9.3 years. The most common aetiologies were proliferative diabetic retinopathy (n=43) and central retinal vein occlusion (n=24). The mean IOP decreased from 36.8±12.5 mm Hg at baseline to 15.8±7.5 mm Hg at 2-year follow-up (p<0.001) and the number of IOP-lowering medications reduced from 3.4±0.8 to 1.5±1.1 (p<0.001). The cumulative rate of failure increased from 3.1% (95% CI 1.1% to 11.8%) at 1 year to 33.8% (95% CI 20.4% to 52.5%) at 2 years. Multivariable analysis showed that eyes with open angles had a lower risk of failure (HR 0.17, 95% CI 0.10 to 1.03, p=0.09). The logarithm of minimum angle of resolution visual acuity declined from 0.98±0.7 to 1.8±1.0 at 2 years (p<0.001).ConclusionApproximately one-third of NVG eyes that received the AADI failed after 2 years of follow-up similar to other series. Early AADI implantation at the open angle stage of NVG may yield better results.

AimsTo report treatment outcomes of slow-coagulation continuous-wave transscleral cyclophotocoagulation (TSCPC) as an initial surgical intervention in patients with neovascular glaucoma (NVG).MethodsA retrospective study including 53 patients (mean age of 69.6±16.6 years and mean follow-up of 12.7±8.9 months) with a diagnosis of NVG and no previous incisional glaucoma or cyclophotocoagulation surgeries. All patients underwent slow-coagulation continuous-wave TSCPC (1250-milliwatt power and 4-second duration).Primary outcome measure was surgical success defined as an intraocular pressure (IOP) from 6 to 21 mm Hg with a reduction ≥20% from baseline, no reoperation for glaucoma and no loss of light perception vision. Secondary outcome measures include IOP, glaucoma medications, visual acuity (VA) and complications.ResultsIOP decreased from 40.7±8.6 mm Hg preoperatively to 18.4±12.2 mm Hg postoperatively (p<0.001). The preoperative number of glaucoma medications dropped from 3.3±1.1 at baseline to 2.0±1.5 at the last postoperative visit (p<0.001). The cumulative probabilities of success at 12 and 24 months were 71.7% and 64.2 %, respectively. Mean logarithm of the minimum angle of resolution VA was relatively unchanged from 2.27±0.63 to 2.25±0.66 at the last follow-up visit (p=0.618). The most common observed complications were decrease in baseline VA (13.2%) and anterior chamber inflammation (9.4%).ConclusionsSlow-coagulation TSCPC is an effective and relatively safe initial surgical intervention in medically uncontrolled NVG.

Abstract Purpose: To compare the effect of intravitreal ranibizumab (IVR) or intravitreal dexamethasone implants (IVD) on regression of hyperreflective dots (HRDs) on optical coherence tomography (OCT) B-scan in patients with branch retinal vein occlusion (BRVO). Methods: 37 eyes of 37 patients with cystoid macular edema who received IVR or IVD and followed up for at least 12 months were included in this study. The patients were divided into three groups according to intravitreal treatment. Group 1 consisted of 12 eyes who received only IVD, group 2 consisted of 10 eyes who received only IVR on a pro re nata and group 3 consisted of 15 eyes who received both IVD and IVR. OCT parameters (CMT, number of HRDs, status of external limiting membrane (ELM) and ellipsoid zone (EZ)) and best-corrected visual acuity (BCVA) were compared between the groups over the follow-up time. HRDs were categorized as HRD in inner retinal layers (from the internal limiting membrane to the inner nuclear layer) or HRD in outer retinal layers (from the outer plexiform layer to the outer border of the photoreceptor layer).Results: There was no significant difference between groups in terms of BCVA, CMT, HRDs in the inner and the outer retinal layers at baseline visit. (p˃0.05 for all) Comparing the baseline values in all groups, a significant decrease was observed in CMT in the first year. (For group 1; p=0.013, group 2; p=0.010; group 3, p<0.001) The BCVA was significantly increased after 1 year in all groups. (p=0.001, p=0.006, p<0.001) The mean number of HRDs in inner and outer retinal layers were significantly decreased in group 1 and group 3. (For group 1; p<0.001, p=0.001, for group 3; p<0.001, p<0.001) However, there was no significant difference in terms of the mean number of HRDs in inner and outer retinal layers for group 2. (p=0.134, p=0.477) At the first year, the number of HRDs in inner and outer retinal layers was significantly lower in group 1 and group 3 than group 2. (For inner HRDs; group 1 vs. group 2 p=0.007, group 2 vs. group 3 p<0.001. For outer HRDs group 1 vs. group 2 p<0.001, group 2 vs. group 3 p<0.001.) The BCVA was higher in group 3 than group 2 at 1year. (p=0.048). There was no significant difference in terms of post-treatment CMT and the number of HRDs between group 1 and group3 in posthoc tests (p=0.621, p=0.876, and p=0.632).Conclusion: The reduction in HRDs at 12 months and better BCVA after IVD intimates that the HRDs should be considered as inflammatory markers in the follow-up of CME in BRVO. Thus, IVD injection could be more appropriate for patients with higher HRDs after BRVO.

Objective: To investigate intravitreal aflibercept (IVA) injection as an adjunctive treatment to trabeculectomy with mitomycin C (TMC) and panretinal photocoagulation (PRP) for neovascular glaucoma (NVG).Materials and Methods: PRP and IVA (2 mg/0.05 ml) injection were given, and TMC was performed within 2weeks after IVA. Additional PRP, laser suture lysis, subconjunctival 5-fluorouracil injection, and bleb needlingwere performed after TMC if indicated. Best corrected visual acuity (BCVA), intraocular pressure (IOP), surgicalcomplications, and number of anti-glaucoma medications were collected.Results: Five eyes from 5 consecutive patients were included. Two eyes had proliferative diabetic retinopathy (PDR), 2 central retinal vein occlusion, and 1 ocular ischemic syndrome (OIS) (mean initial IOP: 46.8±6.8 mmHg). NVI regression occurred in one eye after PRP alone, and in one eye after PRP and IVA resulting in a good IOP control with topical medical therapy. The other 3 underwent TMC. The preoperative IOP was 34 (OIS), 54 (PDR), and 50 (PDR) mmHg. The 3-month postoperative IOP decreased to 8, 8, and 4 mmHg, respectively, and to 21, 10, and 6 mmHg, respectively, at the last visit. Only the one OIS eye required postoperative topical IOP-lowering medications. Final BCVA was improved, unchanged, and decreased in 2, 2, and 1 eye, respectively. No intraoperative/postoperative complications or NVI recurrence were observed (mean follow-up: 10.7 months).Conclusion: Intravitreal aflibercept was shown to be a potentially effective additional treatment to PRP and TMC in patients with NVG.

Purpose. Ischemic central retinal vein occlusion (CRVO) eyes are at high risk of developing neovascular glaucoma (NVG). Our purpose is to investigate the effect of anti-VEGF therapy for macular edema after CRVO on the development of neovascular glaucoma (NVG) in ischemic CRVO eyes.Methods. This is a retrospective case series of 44 eyes from 44 patients with CRVO treated with anti-VEGF therapy for macular edema. The primary outcome was the development of NVG.Results. Of the 44 eyes, 14 eyes had ischemic CRVO, and 30 eyes had nonischemic CRVO. Nonischemic eyes received a mean of 8.4 anti-VEGF doses, over mean follow-up of 24 months. One nonischemic eye (3.3%) developed NVD but not NVG. The 14 ischemic eyes received a mean of 5.6 anti-VEGF doses, with mean follow-up of 23 months. Of these 14 ischemic eyes, two eyes (14%) developed iris neovascularization and 3 eyes (21%) developed posterior neovascularization. Three of these 5 eyes with neovascularization progressed to NVG, at 19.7 months after symptom onset, on average.Conclusion. Anti-VEGF therapy for macular edema may delay, but does not prevent, the development of ocular NV in ischemic CRVO. Significant risk of NVG still exists for ischemic CRVO eyes.

Background: There are few data on the long-term risk of venous thromboembolism (VTE) among stroke survivors. We aimed to compare the incidence of VTE amongst patients with ischemic stroke versus those with intracerebral hemorrhage (ICH). Methods: We identified all adults discharged from nonfederal acute care hospitals in CA, NY, and FL between 2005 and 2012 with previously validated ICD-9-CM codes for ischemic stroke and ICH. Our primary outcome of VTE was defined as pulmonary embolism or deep vein thrombosis. To capture incident cases of VTE, we excluded patients with a VTE prior to or during the index stroke. Kaplan-Meier survival statistics were used to calculate the cumulative rate of incident VTE. Cox regression was used to compare the risk of VTE after stroke while adjusting for demographics, vascular risk factors, and Elixhauser comorbidity index. As there was a violation of the proportional-hazards assumption, we calculated separate hazard ratios (HR) for each year of follow-up. Results: We identified 834,660 patients with stroke, of whom 712,440 (85.3%) had ischemic stroke and 112,220 (14.7%) had ICH. Over a mean follow-up of 2.8 (+/-2.4) years, 19,937 (2.4%) developed VTE. After 7 years, the cumulative rate of VTE was 4.7% (95% confidence interval [CI], 4.5-4.9%) in patients with ICH and 4.4% (95% CI, 4.3-4.5%) in patients with ischemic stroke. In multivariable analysis, VTE risk was higher in the first year after ICH compared to ischemic stroke (HR 1.51; 95% CI, 1.43-1.58). However, following the first year, the hazard of VTE was higher among patients with ischemic stroke versus those with ICH (Figure). Conclusions: The risk of VTE after stroke varies by stroke type and time. Patients with ICH have a higher risk of VTE in the first year after stroke as compared to those with ischemic stroke while patients with ischemic stroke have a higher risk beyond 1 year.

Purpose. One of the most difficult refractory glaucomas is the neovascular type (NVG), and its association with dense cataract adds to this difficulty. This study aimed to provide results of the triple surgical procedure for such conditions. Methods. 12 eyes of 12 patients with NVG and dense cataract were included in this case series study. The mean age of patients was 57.25 ± 5.9 years. The mean preoperative intraocular pressure (IOP) was 47.25 ± 4.04 mmHg with maximum antiglaucoma therapy. The mean best corrected distant visual acuity (BCDVA) in LogMAR was 2.13 ± 0.38. All patients received intravitreal injection of 1.25 mg (0.05 ml) bevacizumab followed by phacoemulsification, pars plana vitrectomy (PPV) including panretinal photocoagulation (PRP), and trabeculectomy with mitomycin C (MMC). Mean IOP and BCDVA changes were the main outcome results of this study. Results. The follow-up period was 2 years. The mean BCDVA was improved to 1.22 ± 0.35, 1.13 ± 0.34, 1.12 ± 0.37, 1.06 ± 0.38, and 1.01 ± 0.37 at 1, 3, 6, 12, and 24 months, respectively, after this procedure. This improvement was statistically significant when compared with preoperative BCDVA (P<0.0001). The mean postoperative IOP was dropped to 20.08 ± 4.1, 17.08 ± 2.1, 17.17 ± 5, 15.75 ± 4.7, and 16.17 ± 6.1 mmHg, respectively. At the last follow-up, the mean IOP was statistically significantly lower than preoperative IOP (P<0.0001) at the previously mentioned time points. The success rate was complete in 90.9% of eyes and qualified in 100% of eyes. Iris and angle neovascularization had regressed significantly in all patients, and no serious complications occurred during the follow-up period. Conclusions. This triple surgery can safely improve patients with NVG and dense cataract regarding BCDVA and IOP control. This trial is registered with NCT04143620.

AbstractObjectiveTo present evidence on the burden and outcomes of co-morbidities among severely malnourished (SAM) children admitted to outpatient therapeutic programme (OTP) facilities in the conflict setting of Borno, Nigeria.DesignRetrospective medical chart review.SettingFacility-based study.ParticipantsChildren aged 6–59 months with SAM enrolled in OTP between June and November 2016 whose medical records were analysed. Only pneumonia and diarrhoea were examined due to data limitations. Stata software was used for descriptive, multivariate and survival analyses.ResultsRecords of 396 children with median age of 15 months were identified and analysed from the date of enrolment to exit from OTP. Mean length of stay in OTP was 61d, with co-infected SAM children having shorter stay (P=0·006). Of the total, 148 (37·4 %) had at least one co-morbidity (pneumonia or diarrhoea), of which thirty-nine (26·4 %) had both. Cumulative rate of mortality during follow-up time was 9·5 (95 % CI 6·0, 15·1) per 10 000 child-days; SAM children with co-morbidities were ten times more likely to die than those without (hazard ratio=10·2; 95 % CI 3·4, 31·0). In multivariable analysis, co-morbidity (P=0·01), oedema (P=0·003), dehydration (P=0·02) and weight on admission (P=0·01) were associated with mortality. Both recovery and defaulter rates (57·8 and 36·1 %, respectively) did not meet SPHERE standards.ConclusionsChildren with SAM and co-morbidities are less likely to survive, presenting a significant barrier in improving child survival. The findings call for integrated OTP models that incorporate clinical algorithms and ensure prompt referral for SAM children with co-morbidity.

AimTo describe an extensive scleral excision technique to treat uveal effusion in nanophthalmic eyes.MethodsThis prospective, interventional series of eight eyes of five consecutive patients with nanophthalmos underwent scleral window surgeries. Ninety per cent of the scleral thickness, extending from immediately behind the extraocular muscle insertions to the vortex veins for 3 and 1/4 quadrants, was removed. The main outcome measure was resolution of the uveal effusions.ResultsEight eyes of five patients (one female and four male) with a mean age of 46 years were studied. The mean (range) axial length was 16.1 mm (14.6–17.6 mm), and the mean refractive error was +13.6 dioptres (+10.75 to +16.00 dioptres). Following scleral excision surgery, all uveal effusions resolved within an average (±SD) of 13.9 (±8.7) days. The uveal effusion recurred in only one eye that had a vasoproliferative retinal tumour. The mean best corrected visual acuity improved from 0.69 logarithm of the minimum angle of resolution (logMAR) (Snellen equivalent: 20/97) at baseline to 0.51 logMAR (Snellen equivalent: 20/64; Wilcoxon paired t-test: p=0.016) after a mean follow-up of 35.6 months.ConclusionThe circumferential scleral window technique produces rapid resolution of uveal effusion in nanophthalmic eyes. No adverse effects were noted after surgery and the clinical effect was durable through 1 year.Trial registration numberNCT03748732.

Object Conventional endovascular therapy for carotid stenosis involves placement of an embolic protection device followed by stent insertion and angioplasty. A simpler approach may be placement of a stent alone. The authors determined how often this approach could be used to treat patients with carotid stenosis, and assessed which factors would preclude this approach. Methods Over a period of 6 years, 97 patients with symptomatic carotid stenosis were treated with the intention of using a “stent-only” approach. Arteries in 77 patients (79%) were treated with stents alone, 13 required preinsertion balloon dilation, 6 postinsertion dilation, and 1 both pre- and postinsertion dilation. Results The mean stenosis according to North American Symptomatic Carotid Endarterectomy Trial criteria was reduced from 82 to 40% in the stent-only group and from 89 to 37% in the stent and balloon angioplasty group. The 30-day stroke and death rate was 7.2%. Patients were followed for a mean of 15 months. In the stent-alone group, the mean preoperative Doppler peak systolic velocity (PSV) was 409 cm/second, with an internal carotid artery/common carotid artery (ICA/CCA) ratio of 7.2. At follow-up review, the PSV decreased to 153 cm/second and the ICA/CCA ratio to 2.1. In the angioplasty group the mean preoperative PSV was 496 cm/second and the ICA/CCA ratio was 9.2, decreasing to 163 cm/second and 2, respectfully, at follow-up evaluation. Restenosis occurred in 12.8% of patients at 6 months and in 15.9% at 1 year. One stroke occurred during the follow-up period in each group. Using multivariable analysis, factors precluding the “stent-only” approach were as follows: severity of stenosis, circumferential calcification, and no history of hyperlipidemia. Conclusions Balloons may not be required to treat all patients with carotid stenosis. A stent alone was feasible in 79% of patients, and 79% of patients were alive and free from ipsilateral stroke or restenosis at 1 year. Restenosis rates with this approach are higher than with conventional angioplasty and stent insertion. Carotid arteries with very severe stenoses (> 90%) and circumferential calcification may be more successfully treated with angioplasty combined with stent placement.

Objective To compare the growth of infants with moderate to severe laryngomalacia who underwent supraglottoplasty to the growth of those treated with medical therapy alone. Study Design Case-control study of patients treated between 2008 and 2013. Setting Tertiary care pediatric otolaryngology practice. Subjects and Methods Fifty-one infants newly diagnosed with moderate to severe congenital laryngomalacia. Seventeen infants underwent supraglottoplasty and 34 matched controls had medical management, which included acid suppression therapy, speech and swallowing therapy, and/or high-calorie formula. The primary outcome measure was weight percentile recorded at the second clinic visit and at the last available follow-up. The secondary outcomes were the need for primary or revision supraglottoplasty, tracheostomy or gastrostromy, or the development of or persistence of failure to thrive. Results There was no difference in the mean weight percentile between the surgical and nonsurgical groups at the time of last follow-up ( P = .89). The mean change in weight percentile during the study period was 32% (95% CI, 15%-48%) in the supraglottoplasty group and 31% (95% CI, 22%-40%) in the medical group ( P = .97). Five of 5 (100%) patients with failure to thrive managed surgically and 10 of 10 (100%) managed medically were above the fifth percentile at the end of the follow-up period. One (3%) patient in the medical management group required tracheostomy and gastrostomy tube placement. Conclusions Medical management and close observation of infants with moderate to severe congenital laryngomalacia may be a viable alternative to supraglottoplasty in appropriately selected infants.
