Epidemiological trends in 1452 cases of retinoblastoma from the Surveillance, Epidemiology, and End Results (SEER) registry.

OBJECTIVE: To assess retinoblastoma epidemiological trends in the Surveillance, Epidemiology, and End Results (SEER) registry. METHODS: All cases of retinoblastoma in the SEER database from 1973 to 2009 were identified. Kaplan-Meier survival analyses were performed for pathological grade, patient age, sex, year of diagnosis, and treatment modality. Cox proportional hazards regression assessed the impact of patient and tumour characteristics on survival. RESULTS: 1452 cases of retinoblastoma were analyzed. The mean patient age at diagnosis was 1.44 years. The tumour was unilateral in 71.0% and bilateral in 29.0%. The mean follow-up was 129.1 months. Overall survival increased during the study interval. Patients with bilateral tumours were diagnosed at an earlier age (0.46 years) than patients with unilateral disease (1.77 years; p < 0.0001). Bilateral retinoblastoma (90.3% 10-year overall survival) was associated with decreased overall survival than unilateral retinoblastoma (96.1% 10-year overall survival). Bilateral retinoblastoma was also associated with an increased incidence of nonocular malignancies (7.8%) compared with unilateral retinoblastoma (1.3%; p < 0.0001). Grade 1 tumours were diagnosed at a younger age (0.94 years) than grade 3 (2.24 years) and grade 4 tumours (2.14 years; p < 0.0001). Lower grade and lower stage tumours were independently associated with increased survival. In multivariate Cox proportional hazards analysis, T stage and laterality were the only covariates that correlated with overall survival. CONCLUSIONS: There appear to be associations between retinoblastoma tumour features such as tumour stage, pathological grade, and laterality with patient characteristics such as age at diagnosis, overall survival, and second malignancies.

SMOKING IS A RISK FACTOR FOR PROLIFERATIVE VITREORETINOPATHY AFTER TRAUMATIC RETINAL DETACHMENT.

PURPOSE: To determine the incidence of retinal redetachment due to proliferative vitreoretinopathy after open-globe trauma in smokers and nonsmokers. METHODS: A total of 892 patients comprising 893 open-globe injuries, in whom 255 eyes were diagnosed with a retinal detachment, and 138 underwent surgical repair were analyzed in a retrospective case-control study. Time to redetachment was examined using the Kaplan-Meier method and analysis of risk factors was analyzed using Cox proportional hazards modeling. RESULTS: Within one year after retinal detachment surgery, 47% (95% CI, 39-56%) of all 138 repaired retinas redetached because of proliferative vitreoretinopathy. Being a smoker was associated with a higher rate of detachment (adjusted hazard ratio 1.96, P = 0.01). As shown in previous studies, the presence of proliferative vitreoretinopathy at the time of surgery was also an independent risk factor for failure (adjusted hazard ratio 2.13, P = 0.005). Treatment with vitrectomy-buckle compared favorably to vitrectomy alone (adjusted hazard ratio 0.58, P = 0.04). Only 8% of eyes that redetached achieved a best-corrected visual acuity of 20/200 or better, in comparison to 44% of eyes that did not redetach (P < 0.001). CONCLUSION: Proliferative vitreoretinopathy is a common complication after the repair of retinal detachment associated with open-globe trauma, and being a smoker is a risk factor for redetachment. Further study is needed to understand the pathophysiologic mechanisms underlying this correlation.

PARS PLANA VITRECTOMY COMBINED WITH CATARACT EXTRACTION: A Comparison of Surgical Outcomes Using Single-Piece and Multipiece Foldable Intraocular Lenses.

PURPOSE: To assess whether complication rates are comparable between phacovitrectomy using multipiece lenses versus single-piece foldable intraocular lenses. METHODS: Single-center, multisurgeon retrospective comparative consecutive interventional case series. Two hundred and seventy-one patients undergoing combined phacovitrectomy performed during a single session at a university-based ophthalmology practice from 2004 to 2013 were identified, of whom 184 met study inclusion criteria; 56.4% patients had diabetes mellitus. RESULTS: There was no difference in the total incidences of postoperative complications between combined surgery using single-piece and multipiece intraocular lenses (P = 0.80) or among individual complications between the 2 groups, including synechiae (2.7 vs. 5.3%; P = 0.61), pupillary capture (0.7 and 2.6%; P = 0.36), and lens subluxation (1.4 and 0%; P > 0.99). There was no difference in the incidences of complications in patients with diabetes mellitus compared with nondiabetic patients undergoing phacovitrectomy (P = 0.13). Complication rates did not differ between single-piece and multipiece lenses with the use of postoperative intravitreal tamponade (P = 0.67). CONCLUSION: Single-piece, acrylic intraocular lenses are associated with a low rate of surgical complications after combined phacovitrectomy and represent an acceptable alternative to multipiece foldable intraocular lenses under the circumstances and using the surgical techniques implemented in this study.

Epidemiological trends in uveal melanoma.

BACKGROUND: There has been a recent evolution in the management of uveal melanoma in regard to prognostic evaluation and treatment modalities. This study aims to evaluate the epidemiological trends of uveal melanoma since 1973 by using the Surveillance, Epidemiology, and End Results (SEER) Registry. METHODS: A total of 7043 uveal melanoma cases from the SEER database were retrospectively analysed, spanning 1973 to 2009. The main outcome measures were disease specific and overall patient survival. RESULTS: The mean patient age at diagnosis was 61.4 years, which has increased over the last 37 years. The mean follow-up interval was 85.9 months. The proportion of tumours demonstrating spindle cell histology has decreased. Spindle cell tumours yielded superior disease-specific survival to epithelioid and mixed tumours. The median age at diagnosis of spindle cell tumours (60 years) was significantly younger than epithelioid tumours (65 years) and mixed tumours (64 years old; p < 0.0001). In a Cox proportional hazards regression analysis, tumour histology, T stage and age at diagnosis were associated with disease-specific survival. The prevalence of cutaneous melanoma was increased in patients with uveal melanoma, but the lifetime prevalence of other primary cancers was not appreciably increased. CONCLUSIONS: The SEER data set demonstrates epidemiological trends in patient age at diagnosis and tumour histology over the last 37 years. Several patient and tumour characteristics are predictors of disease-specific survival. These findings have implications for disease surveillance and prognostic counselling.

Feasibility and efficacy of a mass switch from ranibizumab (Lucentis) to bevacizumab (Avastin) for treatment of neovascular age-related macular degeneration.

PURPOSE: To assess the feasibility and potential obstacles of a departmental switch from ranibizumab (Lucentis, Genentech, South San Francisco, CA) to bevacizumab (Avastin, Genentech) for the treatment of neovascular age-related macular degeneration (AMD). METHODS: A total of 154 eyes treated for wet AMD with ranibizumab or bevacizumab were examined over a 10-month period. The treatment protocol was monthly induction therapy followed by injections as needed for macular edema or subretinal fluid on optical coherence tomography, new hemorrhage or edema on examination, worsening vision, or leakage on fluorescein angiography. Central subfield thickness and pinhole vision were the main treatment outcomes. Study windows were compared using t tests and Mann-Whitney U tests. Statistical significance was defined as a P value of <0.05. RESULTS: The majority of patients (88%) were willing to accept a bevacizumab injection. There was no difference in frequency of injection, central subfield thickness, visual outcome, or endophthalmitis rate between the ranibizumab and bevacizumab groups. A small subset of patients (4.5%) appeared to respond more favorably to ranibizumab than bevacizumab. CONCLUSIONS: Bevacizumab appears to be a cost-effective alternative to ranibizumab for the treatment of neovascular AMD. Patients previously treated with ranibizumab are typically willing to switch to bevacizumab. In the overwhelming majority of patients, there is no major decline in clinical status. However, select patients may respond better to ranibizumab injections.

Epidemiological trends in malignant lacrimal gland tumors.

OBJECTIVE: To describe epidemiological trends in lacrimal gland malignancies in the United States. STUDY DESIGN: Retrospective database review. SETTING: Multicenter registry. SUBJECTS AND METHODS: A total of 702 malignant tumors of the lacrimal gland from the Surveillance, Epidemiology, and End Results database were included in the study. Disease-specific and overall survival were the primary outcome measures. Kaplan-Meier survival curves were generated for multiple patient and tumor characteristics, including race, histology, TNM tumor stage, age at diagnosis, radiotherapy, gender, and tumor grade. Cox proportional hazards regression was performed to assess the impact of patient and tumor characteristics on survival. RESULTS: Lymphoma (58.0%), adenoid cystic carcinoma (13.4%), adenocarcinoma (3.8%), and mucoepidermoid carcinoma (3.6%) accounted for most tumors. Lymphoma was associated with more favorable survival rates, while adenocarcinoma, adenoid cystic carcinoma, and mucoepidermoid carcinoma were associated with worse prognosis. There was a steady increase in the proportion of lymphoma diagnosed since 1973. In a multivariate Cox proportional hazards regression model, tumor histology remained as the only covariate correlated with disease-specific survival. CONCLUSION: Patient characteristics and survival rates differ between lymphoma, adenoid cystic carcinoma, adenocarcinoma, and mucoepidermoid carcinoma. The proportion of lacrimal gland cancer diagnosed as lymphoma has steadily increased over time. Cox proportional hazards regression analysis demonstrated tumor histology as one of the most important factors in patient survival. These results augment our understanding of the expected disease course of lacrimal gland malignancies.

Predictors and outcomes of ocular hypertension after open-globe injury.

PURPOSE: Evaluate predictors and outcomes of ocular hypertension after open-globe injury. PATIENTS AND METHODS: This is a retrospective, case-control study reviewing records of consecutive patients with open-globe injuries treated at Massachusetts Eye and Ear Infirmary between February 1999 and January 2007. Of 658 patients treated, 382 had at least 2 months of follow-up and sufficient data to be included. Main outcome measures are visual acuity, intraocular pressure (IOP), and type of glaucoma intervention employed. RESULTS: Sixty-five (17%) patients developed ocular hypertension defined as IOP≥22 mm Hg at >1 visit or requiring treatment. Increased age (P<0.001), hyphema (0.025), lens injury (P<0.0001), and zone II injury (P=0.0254) are risk factors for developing ocular hypertension after open-globe injury. Forty-eight (74%) patients with ocular hypertension were treated medically, 8 (12%) underwent filtering or glaucoma drainage device surgery, 5 (8%) had IOP normalization with observation, while 4 (6%) required anterior chamber washout with no other glaucoma surgery. Patients with ocular hypertension had an average maximum IOP=33.4 mm Hg at a median follow-up of 21 days, with most patients maintaining normal IOP at all follow-up time points. Visual acuity improved over time with median acuity of hand motions preoperatively, and 20/60 at 12 and 36 months. CONCLUSIONS: Ocular hypertension is a significant complication after open-globe injury that sometimes requires surgical intervention. Predictive factors can alert physicians to monitor for elevated IOP in the first month after trauma. Most patients with traumatic ocular hypertension had improved visual acuity and IOP normalization over time.

Radiotherapy in parotid acinic cell carcinoma: does it have an impact on survival?

OBJECTIVE: Acinic (or acinar) cell carcinoma (ACC) represents approximately 10% of salivary gland malignant tumors and most commonly occurs in the parotid gland. It carries a propensity for locoregional and distant metastasis. Although it is selectively used as an adjuvant in this tumor, radiotherapy (RT) has not been sufficiently examined in large population studies for survival impact. DESIGN: Retrospective database review. SETTING: Tertiary care center. PATIENTS: A total of 1241 cases of parotid ACC in the Surveillance, Epidemiology, and End Results (SEER) Program database from 1988 to 2007 were identified and analyzed. INTERVENTIONS: Comparison groups were surgery and surgery plus RT. Kaplan-Meier survival curves were generated for oncologic stage and histologic grade. MAIN OUTCOME MEASURES: Overall survival. RESULTS: A total of 969 patients had sufficient staging data for inclusion. When comparing surgery with surgery with adjuvant RT, there was no statistical difference in overall survival when stratifying for stage I (P = .57), stage II (P = .37), stage III (P = .25), and stage IV (P = .24) tumors. Similarly, adjuvant RT did not demonstrate a survival advantage when stratified by histologic grade of tumor. The highest-grade and highest-stage tumors were fewer in number, however. CONCLUSIONS: To our knowledge, this study represents the largest cohort of patients treated for ACC of the parotid. Adjuvant RT does not seem to provide a significant survival advantage for early-stage or lower-grade parotid ACC. Radiotherapy for highest-stage and highest-grade tumors requires further study.

Surgical rehabilitation of the open globe injury patient.

PURPOSE: To describe the long-term surgical course of patients with open globe injury. DESIGN: Retrospective case series. METHODS: Patients with open globe injuries (848 in total) treated surgically at the Massachusetts Eye and Ear Infirmary between 2000 and 2009 were retrospectively reviewed. Data from presentation, initial repair, and follow-up surgery were analyzed. RESULTS: Among 848 injuries, 1415 surgical procedures were performed. The mean follow-up time was 19.7 months, including 6017 visits. On average, patients required 1.7 surgeries and 7.1 follow-up visits. Factors predicting follow-up surgery included more severe ocular trauma score, worse prerepair visual acuity, retinal hemorrhage, anterior vitrectomy at primary repair, pars plana vitrectomy at primary repair, and lensectomy at primary repair. Patients with zone II injury, hemorrhagic choroidal detachment, and a history of previous ocular surgery tended to require follow-up surgery less frequently. Patients requiring a second surgery tended to have worse visual acuity at presentation and postrepair. Postoperative visual outcomes were worse for patients who underwent vitreoretinal follow-up surgery, likely because of mechanism of injury. Variables associated with inferior visual outcome were worse prerepair visual acuity, postoperative afferent pupillary defect (APD), old age, scleral laceration, and retinal detachment. CONCLUSION: Open globe injuries require significant surgical follow-up. Patients requiring multiple operations tended to have worse postoperative visual acuity. Patients who underwent vitreoretinal surgery had overall worse visual outcomes. While the first year of surveillance appears to be pivotal in the course of an open globe injury, these patients can expect long-term care from comprehensive and subspecialty ophthalmologists.

Systems biology-based analysis implicates a novel role for vitamin D metabolism in the pathogenesis of age-related macular degeneration.

Vitamin D has been shown to have anti-angiogenic properties and to play a protective role in several types of cancer, including breast, prostate and cutaneous melanoma. Similarly, vitamin D levels have been shown to be protective for risk of a number of conditions, including cardiovascular disease and chronic kidney disease, as well as numerous autoimmune disorders such as multiple sclerosis, inflammatory bowel diseases and type 1 diabetes mellitus. A study performed by Parekh et al. was the first to suggest a role for vitamin D in age-related macular degeneration (AMD) and showed a correlation between reduced serum vitamin D levels and risk for early AMD. Based on this study and the protective role of vitamin D in diseases with similar pathophysiology to AMD, we examined the role of vitamin D in a family-based cohort of 481 sibling pairs. Using extremely phenotypically discordant sibling pairs, initially we evaluated the association of neovascular AMD and vitamin D/sunlight-related epidemiological factors. After controlling for established AMD risk factors, including polymorphisms of the genes encoding complement factor H (CFH) and age-related maculopathy susceptibility 2/HtrA serine peptidase (ARMS2/HTRA1), and smoking history, we found that ultraviolet irradiance was protective for the development of neovascular AMD (p = 0.001). Although evaluation of serum vitamin D levels (25-hydroxyvitamin D [25(OH)D]) was higher in unaffected individuals than in their affected siblings, this finding did not reach statistical significance. Based on the relationship between ultraviolet irradiance and vitamin D production, we employed a candidate gene approach for evaluating common variation in key vitamin D pathway genes (the genes encoding the vitamin D receptor [VDR]; cytochrome P450, family 27, subfamily B, polypeptide 1 [CYP27B1]; cytochrome P450, family 24, subfamily A, polypeptide 1 [CYP24A1]; and CYP27A1) in this same family-based cohort. Initial findings were then validated and replicated in the extended family cohort, an unrelated case-control cohort from central Greece and a prospective nested case-control population from the Nurse's Health Study and Health Professionals Follow-Up Studies, which included patients with all subtypes of AMD for a total of 2,528 individuals. Single point variants in CYP24A1 (the gene encoding the catabolising enzyme of the vitamin D pathway) were demonstrated to influence AMD risk after controlling for smoking history, sex and age in all populations, both separately and, more importantly, in a meta-analysis. This is the first report demonstrating a genetic association between vitamin D metabolism and AMD risk. These findings were also supplemented with expression data from human donor eyes and human retinal cell lines. These data not only extend previous biological studies in the AMD field, but further emphasise common antecedents between several disorders with an inflammatory/immunogenic component such as cardiovascular disease, cancer and AMD.

Characteristics of traumatic cataract wound dehiscence.

PURPOSE: To characterize the clinical course of cataract wound dehiscence. DESIGN: Retrospective, comparative case series. METHODS: Charts of open globe injuries (848 injuries in 846 patients) treated surgically at the Massachusetts Eye and Ear Infirmary between 2000 and 2009 were retrospectively reviewed. Time from original surgery to wound dehiscence, type of initial surgery, Ocular Trauma Score, age, gender, mechanism of injury, and visual acuity were analyzed. RESULTS: Of 846 patients with 848 open globe injuries, 63 experienced cataract wound dehiscence. The majority of these cataract wounds (89%) were extracapsular cataract extraction (ECCE), with only 7 (11%) phacoemulsification wounds. The mean patient age in the wound rupture group was 78.2 years. Female patients comprised the majority (67%) of this subpopulation. The most common mechanisms of injury were fall (65%), blunt trauma (23%), and motor vehicle accident (7%). The median raw ocular trauma score was 47 in wound dehiscence patients. Visual acuity at presentation was light perception in the wound dehiscence group. The best postoperative visual acuity was significantly worse in the wound dehiscence group (hand motion) than in the remaining patients (20/40; P=.0002). When considering the phacoemulsification patients alone, these patients fared much better, with a median postoperative vision of 20/60. CONCLUSIONS: Despite recent advances in cataract surgery, wound dehiscence remains a significant source of visual disability, mainly in the geriatric population. Rupture ECCE wound patients have a poor visual prognosis. Fortunately, patients with phacoemulsification site dehiscence appear to regain the majority of their vision after open globe repair.

Malignant eccrine spiradenoma: a meta-analysis of reported cases.

BACKGROUND: Malignant eccrine spiradenoma is an aggressive sweat gland tumor with poorly understood behavior and no currently accepted therapeutic regimen. METHODS: An individual patient data meta-analysis with Kaplan­Meier survival curves was performed on 72 reported cases of malignant eccrine spiradenoma. RESULTS: In 35 patients with no distant metastasis, local resection resulted in 100% disease-free survival. Of 7 patients with lymph node but no distant metastasis treated with surgical resection and lymph node dissection, 6 patients remained disease-free at final follow-up evaluation. For the 24 cases with confirmed distant metastatic disease, patient survival did not significantly differ between local resection and surgery with adjuvant chemoradiotherapy (P = .8763). CONCLUSIONS: Heightened awareness is recommended among surgeons likely to treat this entity. An aggressive surgical approach is supported in the absence of metastasis. When lymph nodes are not clinically involved, sentinel node may have a role followed by lymph node dissection in patients with a positive node.

Geriatric traumatic open globe injuries.

PURPOSE: To characterize the pattern of ocular trauma in the geriatric population. DESIGN: Retrospective, comparative case series. PARTICIPANTS: Eight hundred forty-six consecutive patients comprising 848 open globe injuries, of which 166 injuries occurred in geriatric patients (defined as 65 years old or older at the time of injury), with the remaining patients serving as control subjects. METHODS: Charts of open globe injuries (848 in total) treated surgically at the Massachusetts Eye and Ear Infirmary between January 2000 and April 2009 were retrospectively reviewed. MAIN OUTCOME MEASURES: Ocular Trauma Score, age, gender, mechanism of injury, zone of injury, site of injury, time of day, visual acuity at presentation, and best post-repair visual acuity were analyzed. RESULTS: Of 848 open globe injuries, 166 occurred in the geriatric population. The mean patient age in the geriatric group was 79.8 years. Females comprised most (58%) of this subpopulation. The most common mechanisms of injury were fall (65%), blunt trauma (16%), and motor vehicle accident (6%). The geriatric traumas tended to happen in late morning or late at night. There were no cases of endophthalmitis and fewer instances of enucleation in this group. The median raw Ocular Trauma Score was 47 in the geriatric population, compared with 70 in the younger subset (P < 0.0001). The injuries more often were in zones II and III in the geriatric population compared with the nongeriatric population (P < 0.0001). The geriatric patients were much more likely to have undergone previous intraocular surgery (P < 0.0001), which consisted of primarily cataract procedures. Visual acuity at presentation was significantly worse in the geriatric population than the nongeriatric population (P<0.0001). Similarly, the best postoperative visual acuity was worse in the elderly group than the younger group (P < 0.0001). CONCLUSIONS: The elderly represent a unique, yet neglected ocular trauma population. The pattern of ophthalmic injury and outcome differs greatly between the geriatric and nongeriatric populations. A better understanding of these injuries is necessary to improve prevention and treatment strategies for potentially devastating open globe injuries in this susceptible population.

Characteristics and outcomes of work-related open globe injuries.

PURPOSE: To evaluate the characteristics and outcomes of patients treated for open globe injuries sustained at work and to compare these results to patients injured outside of work. DESIGN: Retrospective chart review of 812 consecutive patients with open globe injuries treated at the Massachusetts Eye and Ear Infirmary between 1999 and 2008. METHODS: A total of 146 patients with open globe injuries sustained at work were identified and their characteristics and outcomes were compared with the rest of the patients in the database. RESULTS: Of the patients injured at work, 98% were men, and the average age of the patients was 35.8 years (17-72 years). The most common mechanism of injury was penetrating trauma (56%); 38 patients examined had intraocular foreign bodies (IOFB). Nine work-related open globe injuries resulted in enucleation. There was a higher incidence of IOFBs (P = .0001) and penetrating injuries (P = .0005) in patients injured at work. Both the preoperative (P = .0001) and final best-corrected visual acuity (P = .0001) was better in the work-related group. The final visual acuity was better than 20/200 in 74.1% of cases of work-related open globe injuries. However, there was no difference observed in the rate of enucleations (P = .4). CONCLUSIONS: Work-related injuries can cause significant morbidity in a young population of patients. Based on average patient follow-up and final visual acuity, those injured at work do at least as well as, if not potentially better than, those with open globe injuries sustained outside of work. While the statistically higher rate of IOFB in the work population is not surprising, it does emphasize the importance of strict adherence to the use of eye protection in the workplace.

Comprehensive analysis of complement factor H and LOC387715/ARMS2/HTRA1 variants with respect to phenotype in advanced age-related macular degeneration.

PURPOSE: To examine the interaction of genotypic variation of 16 single-nucleotide polymorphisms (SNP) in the complement factor H (CFH) and LOC387715/ARMS2/HTRA1 loci with clinical characteristics of age-related macular degeneration (AMD). DESIGN: Retrospective cohort study. METHODS: Eighty-four patients with neovascular AMD were genotyped using direct sequencing or Sequenom iPLEX technology. The Fisher exact test, Cochran-Mantel-Haenszel statistics, and Mann-Whitney U test were used to assess the effect of each SNP with respect to the following phenotypic manifestations: age at diagnosis, gender, affected eye, study and fellow eye visual acuity at diagnosis and at last follow-up, study eye best acuity during follow-up, presence of large drusen and retinal pigment epithelium (RPE) hyperpigmentation in study and fellow eye, choroidal neovascularization (CNV) angiographic subtype (classic vs occult), CNV size, presence of wet AMD in fellow eye, presence of dry AMD in fellow eye, and smoking history. RESULTS: Only SNPs in the LOC387715/ARMS2/HTRA1 (10q26) region were associated with disease phenotypes. The polymorphisms rs10664316 and rs1049331 were associated with a decreased risk of poor visual acuity during follow-up and at diagnosis; rs2672598 and rs2293870 were associated with a decreased risk of RPE hyperpigmentation; rs10664316 was associated with a decreased risk of RPE hyperpigmentation with large drusen in the study eye, but an increased risk of large drusen in the fellow eye; rs11200638 was associated with an increased risk of larger CNV; rs10490924 and rs11200638 were associated with younger age of diagnosis. CONCLUSIONS: Several polymorphisms examined in the LOC387715/ARMS2/HTRA1 locus, but none in the CFH region, correlated with specific phenotypic attributes of AMD.

Treatment of esthesioneuroblastoma: a 16-year meta-analysis of 361 patients.

OBJECTIVES/HYPOTHESIS: This study reviews the published outcomes related to surgical (open, endoscopic, and endoscopic-assisted) and nonsurgical treatment for esthesioneuroblastoma. STUDY DESIGN: Literature meta-analysis. METHODS: A meta-analysis of individual patient data for esthesioneuroblastoma publications between 1992 (the earliest identified description of endoscopic resection) and 2008 was conducted. A total of 49 journal articles, comprising 1,170 cases of esthesioneuroblastoma, were included in the study. Criteria for meta-analysis inclusion were five or more patients in a study with sufficient patient data resolution for analysis. Twenty-three studies comprising 361 patients met all inclusion criteria. The overall treatment and outcome at final follow-up of each patient was recorded. Patients were pooled according to treatment techniques and compared to one another using a Kaplan-Meier survival curve and the Mann-Whitney U test to examine differences in follow-up times and publication years. RESULTS: Log-rank tests showed a greater published survival rate for endoscopic surgery compared to open surgery (P = .0019), even when stratifying for publication year (P = .0018). There was no significant difference in follow-up time. Review of Kadish tumor staging for each modality showed larger tumors were more often treated with an open approach, but open and endoscopic survival measures were comparable. CONCLUSIONS: These results suggest that endoscopic surgery is a valid treatment method with comparable survival to open surgery. Further prospective analysis will be beneficial.

Enucleation for open globe injury.

PURPOSE: To report the experience of enucleation after open globe at an ophthalmic trauma referral center. DESIGN: Retrospective, observational study. METHODS: In an ophthalmic trauma referral center the charts of all patients having suffered an open globe injury between January 1, 2000 and June 30, 2007 were reviewed. Variables assessed were age, gender, type of injury (rupture or laceration [penetrating, intraocular foreign body, or perforating]), ocular trauma score, visual acuity, subsequent enucleation, indication for and timing of enucleation, presence of sympathetic ophthalmia, and length of follow-up. RESULTS: Among 660 open globe injuries, 55 have undergone enucleation (including 4 eviscerations), 11 primarily and 44 secondarily. Eyes with ruptures were significantly more likely to be enucleated than those with injuries attributable to lacerations (P < .001). The most common reason for secondary enucleation was a blind, painful eye. Two patients (0.3%) developed sympathetic ophthalmia and have maintained good vision in the sympathizing eye. CONCLUSIONS: The vast majority of open globes can be repaired without requiring primary enucleation. Secondary enucleation is most commonly carried out for pain. Eyes with no light perception can be closely observed if the patient chooses.

Visual outcomes of vitreoretinal surgery in eyes with severe open-globe injury presenting with no-light-perception vision.

BACKGROUND: Severe ocular trauma causing no light perception (NLP) typically carries a dismal prognosis, and implies no further therapeutic intervention. We have identified a cohort of patients with verified NLP following open-globe injury who have recovered vision of light perception (LP) or better. We evaluated the outcomes of vitreoretinal surgery performed on eyes that were NLP post open-globe injury. METHODS: Retrospective review of outcomes of secondary vitreoretinal surgery performed at Massachusetts Eye and Ear Infirmary from 1 January 2001 to 31 December 2006 on all cases of open-globe repair (OGR) that had NLP prior to OGR or on the first post-operative day. RESULTS: A total of 648 cases of OGR were performed in the study period. Eighty-eight patients had NLP prior to OGR or on the first post-operative day after OGR. Twenty-three patients from the above group (26.1%) spontaneously recovered a vision of light perception (LP) or better. Eight of the 23 patients had a secondary vitreoretinal surgery. All eyes that did not undergo vitreoretinal surgery returned to NLP or became phthisical within 7 months. Among the eight eyes that underwent surgery, five had improvement, with vision ranging from hand motion to 20/70. Prognostic indicators for successful surgical outcome were hand motion or better vision prior to vitreoretinal surgery, recovery of vision within 5 days of OGR, and vitreoretinal intervention within 5 weeks of the initial open-globe injury. CONCLUSION: Patients with severe open-globe injury and NLP occasionally recover LP or better vision. These patients may regain useful vision after vitreoretinal surgery if prompt referral and intervention is attempted and if the spontaneous visual recovery occurs within the first week after OGR.

Measuring the effectiveness of laparoscopic antireflux surgery: long-term results.

OBJECTIVE: To evaluate long-term results and quality of life of patients undergoing laparoscopic antireflux surgery. DESIGN: A validated survey instrument, the Gastroesophageal Reflux Disease-Health-Related Quality-of-Life Scale (GERD-HRQL) was mailed to all patients who underwent laparoscopic fundoplications (LFs) from 1997 to 2006. Additional information was obtained regarding reintervention, satisfaction, and medication use. SETTING: Tertiary care referral center. PATIENTS: Four hundred five consecutive patients who underwent primary or redo LF from 1997 to 2006. MAIN OUTCOME MEASURES: GERD-HRQL score, reoperation rate, and antireflux medication use. RESULTS: A 54% response rate was obtained. Median follow-up was 60 months (range, 4-75 months). In patients who underwent primary LF, the mean (SD) GERD-HRQL score was 5.71 (7.99) (range, 0-45, with 0 representing no symptoms). Seventy-one percent of patients were satisfied with long-term results. Forty-three percent of patients took antireflux medications at some point following surgery; half of these patients had no diagnostic testing to document GERD recurrence. Only 3 patients (1.2%) required reoperation. Patients undergoing redo LF had higher GERD-HRQL scores (mean [SD], 14.25 [10.33]), lower satisfaction (35%), and greater probability of requiring antireflux medication (78%). Patients with body mass indexes (BMIs) (calculated as weight in kilograms divided by height in meters squared) between 25 and 35 had lower GERD-HRQL scores than thin (BMI < 25) and morbidly obese (BMI >/= 35) patients. CONCLUSIONS: Contrary to the medical literature, our results demonstrate that patients undergoing primary LF by an experienced surgical team have near-normal GERD-HRQL scores at long-term follow-up and low reoperation rates and are satisfied with their decision to undergo surgery. Results following redo LF are not as good, highlighting the importance of proper patient selection and surgical technique when performing primary LF.
