RESUMO
PURPOSE: To compare anatomic and functional outcomes in eyes with proliferative diabetic retinopathy (PDR) that were lost to follow-up (LTFU) for more than 6 months after treatment with either intravitreal injection (IVI) of anti-vascular endothelial growth factor (VEGF) agents or panretinal photocoagulation (PRP). DESIGN: Retrospective cohort study. PARTICIPANTS: Fifty-nine patients who were LTFU immediately after treatment for more than 6 months between September 2013 and September 2016. METHODS: Patients with eyes receiving either intravitreal anti-VEGF treatment or PRP with the next follow-up visit occurring more than 6 months after treatment were identified. Visual acuity (VA) and anatomic outcomes at the visit before being LTFU, the return visit, the 6-month visit after return, the 12-month visit after return, and the final visit were gathered and compared between the 2 treatment groups. MAIN OUTCOMES MEASURES: Visual acuity and anatomic outcomes. RESULTS: Seventy-six eyes of 59 patients were included in the study, of which 30 received IVI with anti-VEGF and 46 received PRP. In the anti-VEGF group, mean VA worsened significantly when comparing the visit before being LTFU (0.43±0.38 logarithm of the minimum angle of resolution [logMAR]) with the return visit (0.97±0.80 logMAR; P = 0.001) as well as with the final visit (0.92±0.94 logMAR; P = 0.01). In the PRP group, mean VA worsened significantly when comparing the visit before being LTFU (0.42±0.34 logMAR) with the return visit (0.62±0.64 logMAR; P = 0.03). However, no significant difference was observed at the final visit (0.46±0.47 logMAR; P = 0.38). There was a significantly greater number of eyes with tractional retinal detachment in the IVI group compared with the PRP group at the final visit (10 vs. 1, respectively; P = 0.005). There was a significantly greater incidence of neovascularization of the iris in the IVI arm compared with the PRP arm at the final visit (4 vs. 0, respectively; P = 0.02). CONCLUSIONS: Eyes with PDR that received only intravitreal anti-VEGF demonstrated worse anatomic and functional outcomes after being LTFU compared with eyes that received PRP. Given the potential sequelae of being LTFU, the choice of treatment for PDR must be considered carefully.

PURPOSE: To examine rates of acute infectious endophthalmitis after pars plana vitrectomy (PPV) in eyes that received intraoperative subconjunctival antibiotics versus eyes that did not. METHODS: A retrospective, nonrandomized, comparative case series of 18,886 consecutive cases of transconjunctival 23-, 25-, and 27-gauge PPV over a 5-year period was performed. The impact of prophylactic intraoperative subconjunctival antibiotics on the development of acute infectious postoperative endophthalmitis was examined. RESULTS: Of 18,886 cases of PPV, 14,068 (74.5%) received intraoperative subconjunctival antibiotics, whereas 4,818 (25.5%) did not. Sixteen cases (0.085%, 1/1,176) of post-PPV endophthalmitis were identified. The incidence of endophthalmitis in eyes that received subconjunctival antibiotics was 0.078% (11/14,068 cases, 1/1,282), whereas the incidence in those that did not receive subconjunctival antibiotics was 0.10% (5/4,818 cases, 1/1,000). No statistically significant difference was identified in the incidence of endophthalmitis between those that received subconjunctival antibiotics and those that did not (P = 0.598). Microbial culture was performed in 11 cases with 6 culture-positive cases (5/8 cases that received subconjunctival antibiotics and 1/3 cases that did not). CONCLUSION: Prophylactic subconjunctival antibiotics were not associated with a significantly reduced rate of post-PPV endophthalmitis. With consideration of emerging multidrug-resistant bacteria, routine prophylactic subconjunctival antibiotics may not be justified.

PURPOSE: To quantify foveal avascular zone (FAZ) area and macular vascular density objectively using optical coherence tomography angiography (OCTA) and to examine correlations with visual acuity in eyes with diabetic retinopathy (DR) in the absence of diabetic macular edema. DESIGN: Retrospective observational case series. PARTICIPANTS: Eighty-four eyes from 55 patients with DR and 34 control eyes from 27 age-matched healthy participants. METHODS: All eyes underwent OCTA (RTVue-XR Avanti; Optovue, Inc, Fremont, CA). Integrated automated algorithms were used to quantify FAZ area and macular vascular density. MAIN OUTCOME MEASURES: FAZ area, vessel area density (VAD), vessel length density (VLD), and visual acuity. RESULTS: In each study eye, DR was classified as mild nonproliferative DR (NPDR; n = 32 [38%]), moderate-to-severe NPDR (n = 31 [37%]), or proliferative DR (n = 21 [25%]). Mean FAZ area was greater in diabetic eyes compared with control eyes both in the superficial (0.427 mm2 vs. 0.275 mm2; P < 0.001) and deep (0.616 mm2 vs. 0.372 mm2; P < 0.001) vascular networks. Mean VAD was lower in diabetic eyes compared with control eyes in both the superficial (49.44% vs. 55.09%; P < 0.001) and deep (56.65% vs. 61.32%; P < 0.001) networks. Mean VLD was also lower in diabetic eyes compared with control eyes in both the superficial (17.68 mm-1 vs. 21.55 mm-1; P < 0.001) and deep (21.19 mm-1 vs. 24.38 mm-1; P < 0.001) networks. In all eyes, there was a statistically significant negative correlation between the logarithm of the minimum angle of resolution (logMAR) visual acuity and the vascular density in both the superficial (VAD, ρ = -0.52; VLD, ρ = -0.54; P < 0.001) and deep (VAD, ρ = -0.50; VLD, ρ = -0.50; P < 0.001) networks. A positive correlation was found between logMAR visual acuity and FAZ area in both the superficial (ρ = 0.29; P < 0.01) and deep (ρ = 0.48; P < 0.001) networks. CONCLUSIONS: Automated quantitative algorithms allow for objective assessment of retinal vascular changes in eyes with DR that are correlated to visual acuity. These methods may prove useful in monitoring disease progression and identifying parameters that affect visual function.

PURPOSE: To assess comfort and procedural facility using a 25-gauge trocar cannula as a port to diagnose and treat acute endophthalmitis compared with a standard vitreous tap and injection technique. METHODS: Eighteen consecutive patients with acute endophthalmitis were randomized into two treatment arms: 1) Standard vitreous tap and injection technique, and 2) A technique where a valved 25-gauge trocar cannula is inserted through the pars plana as done in sutureless vitrectomy surgery and subsequent vitreous sampling and injections are performed through the port. A standardized anesthetic protocol was used and subjects were masked to the technique performed. Primary outcomes measured were patient comfort using a Wong-Baker pain scale and standardized physician ease-of-use scoring scale. Secondary outcomes included vitreous sampling success rate and volume of vitreous sample. RESULTS: No significant differences were found when comparing patient comfort (P = 0.340), physician ease-of-use scores (P = 0.796), vitreous sample volume (P = 0.149), successful vitreous taps (P = 0.620), and microbiologic yield (P = 1.000) between treatment arms. There were no adverse events. CONCLUSION: The 25-gauge trocar technique provides a safe, well-tolerated, and equally effective alternative to the standard vitreous tap and injection technique for delivery of intravitreal antibiotics, and procuring of vitreous sample, requiring a single sharp penetration.

BACKGROUND: Since they were first derived more than three decades ago, embryonic stem cells have been proposed as a source of replacement cells in regenerative medicine, but their plasticity and unlimited capacity for self-renewal raises concerns about their safety, including tumour formation ability, potential immune rejection, and the risk of differentiating into unwanted cell types. We report the medium-term to long-term safety of cells derived from human embryonic stem cells (hESC) transplanted into patients. METHODS: In the USA, two prospective phase 1/2 studies were done to assess the primary endpoints safety and tolerability of subretinal transplantation of hESC-derived retinal pigment epithelium in nine patients with Stargardt's macular dystrophy (age >18 years) and nine with atrophic age-related macular degeneration (age >55 years). Three dose cohorts (50,000, 100,000, and 150,000 cells) were treated for each eye disorder. Transplanted patients were followed up for a median of 22 months by use of serial systemic, ophthalmic, and imaging examinations. The studies are registered with ClinicalTrials.gov, numbers NCT01345006 (Stargardt's macular dystrophy) and NCT01344993 (age-related macular degeneration). FINDINGS: There was no evidence of adverse proliferation, rejection, or serious ocular or systemic safety issues related to the transplanted tissue. Adverse events were associated with vitreoretinal surgery and immunosuppression. 13 (72%) of 18 patients had patches of increasing subretinal pigmentation consistent with transplanted retinal pigment epithelium. Best-corrected visual acuity, monitored as part of the safety protocol, improved in ten eyes, improved or remained the same in seven eyes, and decreased by more than ten letters in one eye, whereas the untreated fellow eyes did not show similar improvements in visual acuity. Vision-related quality-of-life measures increased for general and peripheral vision, and near and distance activities, improving by 16-25 points 3-12 months after transplantation in patients with atrophic age-related macular degeneration and 8-20 points in patients with Stargardt's macular dystrophy. INTERPRETATION: The results of this study provide the first evidence of the medium-term to long-term safety, graft survival, and possible biological activity of pluripotent stem cell progeny in individuals with any disease. Our results suggest that hESC-derived cells could provide a potentially safe new source of cells for the treatment of various unmet medical disorders requiring tissue repair or replacement.

PURPOSE: To determine whether topical aqueous suppressants affect the duration of pure expansile intraocular gas in nonvitrectomized eyes. METHODS: A prospective randomized controlled trial was performed on nonvitrectomized patients undergoing retinal detachment repair with scleral buckle or pneumatic retinopexy using 0.3 mL of 100% perfluoropropane (C3F8) gas tamponade. Eyes were randomly assigned to receive topical dorzolamide 2% and timolol 0.5% twice daily postoperatively until gas dissolution or to observation. RESULTS: Twenty-one patients met all inclusion and exclusion criteria. Twelve were randomized to the control group and nine to the dorzolamide-timolol group. In the dorzolamide-timolol group, mean intraocular pressure was 17.4 on postoperative Day 1 and 12.5 on postoperative Week 1 (P = 0.03). In the control group, mean intraocular pressure was 14.5 on postoperative Day 1 and 15.1 on postoperative Week 1 (P = 0.73). The mean duration of C3F8 was 37.8 days in the dorzolamide-timolol group and 40.4 days in the control group (P = 0.70). CONCLUSION: Topical aqueous suppression does not seem to have a significant effect on the duration of pure expansile intraocular C3F8 in nonvitrectomized eyes after pneumatic retinopexy or scleral buckling.

PURPOSE: To describe the clinical characteristics of and risk factors for the development of optic neuropathy after pars plana vitrectomy (PPV) for macula-sparing primary rhegmatogenous retinal detachment (RRD) repair. DESIGN: Retrospective case-control study. PARTICIPANTS: Seven patients who underwent PPV for macula-sparing primary RRD with subsequent development of optic neuropathy and 42 age- and gender-matched control patients undergoing PPV for macula-sparing primary RRD. METHODS: Retrospective chart review of medical and surgical records. MAIN OUTCOME MEASURES: Clinical features of patients who developed optic neuropathy after PPV for macula-sparing RRD and analysis of potential risk factors (age, gender, medical history, surgical technique, intraoperative ocular perfusion pressure [OPP], and operative time). RESULTS: At last follow-up, all 7 patients with optic neuropathy had visual acuity less than 20/200, relative afferent pupillary defects, optic nerve pallor, and visual field defects. A total of 5 of 7 patients (71%) demonstrated intraoperative reduced OPP with associated systemic hypotension compared with 7 of 42 patients (17%) in the control cohort (P = 0.01). CONCLUSIONS: Optic neuropathy after PPV for macula-sparing primary RRD is a rare but potentially devastating complication. Although the cause is often unclear, reduced ocular perfusion due to intraoperative systemic hypotension may be a contributing risk factor in some eyes.

PURPOSE: To report 10 cases of occult choroidal neovascularization (CNV) associated with choroidal nevus managed with intravitreal bevacizumab. METHODS: Interventional case series. Each nevus was examined and imaged with fluorescein angiography, B-scan ultrasonography, and optical coherence tomography. Data were retrospectively analyzed to evaluate outcomes of treatment response and visual acuity. RESULTS: Nine patients presented with CNV overlying a chronic choroidal nevus with a posterior margin within 1.5 mm of the foveola. In the 10th patient, the posterior margin of the nevus was located 10 mm from the foveola with extension of subretinal fluid into the macula. The CNV was subfoveolar in four cases, juxtafoveolar in two cases, and extrafoveolar in four cases. Initial visual acuity was 20/20 to 20/50 in 5, 20/60 to 20/100 in 2, and 20/200 or worse in 3 cases. Clinical features included subfoveolar fluid in nine, exudation in five, and hemorrhage in four cases. Intravitreal bevacizumab (1.25 mg/0.05 cc) was injected with regression of CNV in all 10 cases using 2 to 14 injections (median 3 injections). In 2 eyes, after therapeutic response to bevacizumab later consolidation with photodynamic therapy (juxtafoveolar CNV) (n = 1) or conventional laser (extrafoveolar CNV) (n = 1) was provided. In the remaining 8 eyes, after discontinuation of bevacizumab, there was no recurrence of CNV over mean 10.1 months. At overall mean follow-up of 22.5 months, final visual acuity decreased by 1 line in 4 cases and improved by mean of 3 lines (range, 1-8 lines) in 6 cases. There were no adverse effects from bevacizumab injections. All 10 choroidal nevi remained stable. CONCLUSION: Intravitreal bevacizumab appears to be an effective treatment option for CNV secondary to choroidal nevus. In some cases, depending on the proximity of the CNV to the foveola, photodynamic therapy or conventional laser may be useful adjunctive therapy.

BACKGROUND: Autistic adults have poorer 24-h movement behaviors, including lower levels of physical activity, more time spent being sedentary, and shorter sleep duration than neurotypical adults. Social ecological frameworks posit that 24-h movement behaviors are determined by multi-level domains; however, not known is which multi-level factors are most important to meeting each of the 24-h movement behavior guidelines among autistic adults. OBJECTIVE: This study examined the relative importance of a range of multi-level determinants on meeting guidelines for the 24-h movement behaviors of aerobic physical activity, sedentary behavior, and sleep. METHODS: We administered at cross-sectional electronic survey to a national self-selecting, convenience sample of autistic adults and caregivers of autistic adults residing in the USA. We used machine learning to examine the relative variable importance (VIMP) of 55 multi-level variables with meeting recommendations for physical activity, sedentary behavior, and sleep duration. VIMPs >0 indicate predictive variables/domains. RESULTS: A greater number of group activities attended in the last 3-months, and greater independence in completing activities of daily living were most important to meeting aerobic physical activity guidelines. Group activity participation and marital status were important to meeting sedentary behavior guidelines while having a fewer number of comorbidities was most important to achieving adequate sleep. CONCLUSIONS: These data support hypotheses about the role of family and social level interventions targeting movement behaviors in autistic adults.
RESUMO
PURPOSE: To compare 2 mg intravitreal triamcinolone (IVT) versus 40 mg posterior sub-Tenon triamcinolone acetonide (STT) for the treatment of eyes with pseudophakic cystoid macular edema. METHODS: A retrospective, single-center review of eyes receiving 2 mg IVT between 3/1/2012-3/1/2017 and 40 mg STT between 1/1/2015-3/1/2017. Visual acuity (VA) and central macular thickness (CMT) were recorded at baseline, 1-, 3-, and 6-month follow-up visits. RESULTS: Forty-five eyes were included in the IVT group and 50 eyes in the STT group. Change in VA from baseline to 1, 3, and 6 months was not significantly different between IVT and STT (6 months: 2.3 lines vs. 2.4 lines, p = .10). The IVT group achieved significantly better CMT improvement from baseline compared to STT at 1 month (255 µm vs. 187 µm; p = .03), but this difference was not present at month 3 (214 µm vs. 212 µm; p = .79) or month 6 (176 µm vs. 207 µm; p = .29). During the 6-month follow-up period, approximately 7% of eyes in the IVT group and 12% of eyes in the STT group developed ocular hypertension (p = .43), and all cases were successfully managed with topical anti-ocular hypertensive therapy or observation. CONCLUSIONS: 2 mg IVT and 40 mg STT both achieved significant improvement in vision and CMT with no significant difference between interventions at 3- and 6-month follow-up.

OBJECTIVES: To compare outcomes from patients with acute retinal necrosis (ARN) treated in the acyclovir-only era with those treated in the era of newer antiviral therapies, identify variables affecting outcomes in ARN, and evaluate strategies for fellow eye prophylaxis. DESIGN: Multicenter, nonrandomized, retrospective, interventional series. PARTICIPANTS: A cohort of 58 patients diagnosed with ARN by a retina specialist at 1 of 4 referral centers between 1981 and 2008. The cohort was divided into 2 subgroups: patients treated during the acyclovir-only era (n = 36) and patients treated during the current era of newer antiviral medications (n = 22). INTERVENTION: Intravenous, oral, or intravitreal antiviral medications, including acyclovir, valacyclovir, famciclovir, valganciclovir, ganciclovir, and foscarnet; prophylactic laser retinopexy; aspirin; oral steroids. MAIN OUTCOME MEASURES: Visual acuity, retinal detachment, and fellow eye involvement. RESULTS: A wide range and combination of antiviral agents are currently used for initial and long-term treatment of ARN. Outcomes from the newer antivirals era were similar to those achieved during the acyclovir-only era. In both groups, the incidence of 20/200 or worse visual acuity was 24% per person-year (P = 0.91). The prevalence of retinal detachment was approximately 50% in each group (P = 0.59). No variables, including prophylactic laser retinopexy, were associated with risk of retinal detachment. Two patients (3.4%) developed ARN in the initially unaffected eye. CONCLUSIONS: Current treatment trends vary widely, including single agents or combinations of oral, intravenous, and intravitreal agents. Differing strategies did not affect outcomes. The final visual acuity in ARN was generally poor. Retinal detachment was common and could neither be predicted nor prevented. Development of ARN in the unaffected fellow eye occurred rarely. Long-term oral antiviral treatment strategies varied with unclear relative efficacy. FINANCIAL DISCLOSURE(S): Proprietary or commercial disclosure may be found after the references.

PURPOSE: To compare fluid detection of autosegmented en face to 12-line radial spectral domain optical coherence tomography scan patterns in neovascular age-related macular degeneration. METHODS: Retrospective observational case series. Sixty-seven patients (94 eyes) with neovascular age-related macular degeneration underwent autosegmented en face optical coherence tomography (with associated 304-line raster scan) and 12-line radial scan patterns. Sensitivity and specificity of fluid detection for en face scan and 12-line radial scans were determined by combining radial and 304-line raster scans as a gold standard. RESULTS: Two hundred and fifty-eight en face and 12-line radial spectral domain optical coherence tomography scans were interpreted. Seventy-five scans (58.1%) had fluid, whereas 54 scans (41.9%) did not. En face scan pattern fluid detection sensitivity and specificity was 89.3% and 61.1%, respectively. Twelve-line radial scan pattern fluid detection sensitivity and specificity was 97.3% and 100%, respectively. The difference in fluid detection between scan patterns was statistically significant (P = 0.01). Decreased central macular thickness was associated with false-positive (P = 0.035) and false-negative (P = 0.01) fluid detection on en face scans. CONCLUSION: En face optical coherence tomography alone is not as sensitive or specific as the 12-line radial scan pattern in detecting fluid in neovascular age-related macular degeneration. En face scans should be corroborated with other optical coherence tomography protocols to guide clinical decision making.

Occult macular dystrophy is a rare macular disorder in which patients have bilaterally decreased visual acuity without any significant ophthalmoscopic findings. Using spectral domain optical coherence tomography, the authors found a defect in the junction between the inner and outer segments of the foveal photoreceptors in a patient with occult macular dystrophy.

PURPOSE: To describe metallic intraocular foreign body (IOFB) injuries and identify prognostic factors for visual outcome and globe survival. DESIGN: Interventional, consecutive, retrospective case series. METHODS: setting: Wills Eye Hospital. study population: Ninety-six eyes of 96 patients with metallic intraocular foreign bodies. procedures: Metallic IOFB injuries between January 1991 to June 2002 were reviewed for clinical characteristics, surgical intervention, and outcome. Univariate and multivariate analyses were performed to identify prognostic variables. main outcome measures: Final visual acuity and globe survival. RESULTS: The average patient age was 33.0 years with a male predominance (94%). Forty percent of eyes had a presenting vision of 20/50 or better. Following IOFB removal, 40% of patients required additional interventions. Thirty-one percent of eyes had a final acuity of 20/50 or better. Eight percent of patients ultimately required enucleation or evisceration. Excellent visual outcome (defined as > or =20/50) was associated with multiple variables, including normal lens at presentation and anterior segment IOFB (P< .003). Factors associated with poor visual outcome (defined as <20/200) included uveal prolapse and posterior segment IOFB (P < .0003). Globe loss was associated with younger age, presenting light perception (LP) or no light perception (NLP) vision, BB/pellet injury, and the presence of an afferent pupillary defect (P < .01). CONCLUSIONS: Multiple prognostic factors were identified in this large analysis of metallic IOFB injuries, which may help predict visual outcome and globe survival. Most of these variables were independent of intervention and can be identified at the time of initial presentation.

Preeclampsia is a life-threatening disorder for both the mother and fetus. A 43-year-old woman presented with a 1-day history of bilateral decreased vision and no systemic complaints. Physical examination revealed an abdominal mass and further diagnostic testing revealed a previously unknown pregnancy. Admission resulted in an emergency cesarean section for fetal distress. This case provides a unique primer of the various diagnostic tests and their results in the diagnosis of preeclampsia. It also highlights the critical role ophthalmologists may play in the diagnosis of this potentially devastating disease.

PURPOSE: To determine the incidence of and the risk factors for the development of retinal pigment epithelial (RPE) tears after intravitreal bevacizumab (Avastin) injection for the treatment of exudative age-related macular degeneration (AMD). METHODS: A retrospective, multicentre, consecutive interventional case series of all patients with subfoveal exudative AMD treated with intravitreal bevacizumab between August 2005 and April 2007. The main outcome measures were pre- and post-RPE tear visual acuity and choroidal neovascular membrane lesion types, incidence of tears and time from first injection until development of the tear. RESULTS: A total of 920 eyes with exudative AMD were treated with intravitreal bevacizumab. Fifteen eyes from 15 patients developed a RPE tear for an incidence of 1.6%. The average patient age was 79 years. Fourteen of the fifteen eyes (93%) had an occult subfoveal choroidal neovascular membrane. Forty-seven per cent (7/15) of the RPE tears occurred within the first 6 weeks of treatment, and all tears occurred within the first 18 weeks of treatment initiation. The mean pre-injection visual acuity was 20/100 with a mean post-tear visual acuity of 20/200. In all 10 eyes in which the tear involved the fovea, the final visual acuity was poor. Six of the 15 eyes continued with bevacizumab/ranibizumab (Lucentis) injections after tear development, and four of these six eyes continued to have visual improvement. CONCLUSION: RPE tears occur after intravitreal bevacizumab injections for exudative AMD in approximately 1.6% of eyes and can cause severe vision loss. Maintenance of therapy may help preserve vision after RPE tear development.
