RESUMO

BACKGROUND: Ocular ischemic syndrome is not a common condition so most of these cases are often misdiagnosed or treated as a different entity. Therefore, it is very important for the ophthalmologists to have this condition in mind as a differential so that the patients can be diagnosed and treated as early as possible. A 42 years female presented with painless, progressive diminution of vision in right eye over the period of 1 month. She doesn't give any history of redness of eyes, fever or trauma. There is no history of diabetes mellitus or hypertension as well. On examination, vision in right and left eyes was 1.78 and 0.30 Log Mar Units respectively. On anterior segment examination, revascularization of iris (1o 4 'o'clock hrs) in right eye was noted. On dilated fund us copy, revascularization of disc (1/3rd) was present in right eye. Cotton wool spots blot hemorrhages and micro aneurysms were also noted in right eye. Likewise, attenuation of arteries were noted on both sides. Fund us fluorescent angiography revealed delayed artery covetous and venous phase. Carotid Doppler was done which showed complete occlusion of right common carotid and bilateral internal carotid artery. These findings lead to the diagnosis as ocular ischemic syndrome so she was then referred to the cardiologist who further confirmed that no active intervention was required at present. The patient was planned for right eye pan retinal photocoagulation (PRP) and was completed in 2 sittings and was asked to follow up regularly. CONCLUSION: Early diagnosis and management is very important for uncommon conditions such as ocular ischemic syndrome to prevent further complications.

RESUMO

PURPOSE: The aim of the current study was to compare visco-trabeculotomy (VT) with standard trabeculectomy with mitomycin C (Trab-MMC) in the treatment of quiescent neovascular glaucoma (NVG). METHODS: The study was conducted on 51 eyes of 51 patients presenting with NVG and treated at an Ophthalmic Center in Egypt between March 2014 and April 2017. All study eyes were subjected to a standard protocol of intravitreal injection of ranibizumab followed by panretinal photocoagulation. Eyes were then randomized to either VT or Trab-MMC. Study eyes were followed up for at least 18 months. Success was defined as an intraocular pressure of ≤21 mm Hg and without vision-threatening complications. Complications were noted. RESULTS: The mean ±â€ŠSD (range, median) age of the study patients was 54.1 ±â€Š6.4 (40-67, 54.5) and 52.4 ±â€Š8.8 (38-66, 53) years in the VT (26 eyes) and Trab-MMC (25 eyes) groups, respectively (P = 0.45). The mean ±â€ŠSD (range, median) intraocular pressure (IOP) of the study eyes was 45.19 ±â€Š2.97 (39-52, 45.5) and 45.64 ±â€Š3.56 (3-53, 45) mm Hg on maximal medical therapy in the VT and Trab-MMC groups, respectively (P = 0.61). At 18 months' follow-up, the mean ±â€ŠSD (range, median) IOP of the study eyes was 18.19 ±â€Š2.0 (16-23, 17) and 19.92 ±â€Š2.6 (18-26, 19) mm Hg in the VT and Trab-MMC groups, respectively (P = 0.004). There was no difference in postoperative antiglaucoma medication between the 2 groups (P = 0.62). Complications included hyphema and Descemet split in the VT group and an IOP spike in the Trab-MMC group. Success rates were 84.6% and 80% in the VT and Trab-MMC groups, respectively (P = 0.726). CONCLUSIONS: Both VT and Trab-MMC groups are effective in reducing the IOP in cases of NVG after control of neovascularization with anti-vascular endothelial growth factor and pan retinal photocoagulation.

RESUMO

Idiopathic retinal vasculitis, aneurysms and neuroretinitis (IRVAN) syndrome is a disease characterized by multiple retinal macroanurysms, neuroretinitis and ischemia in peripheral vessels, which are difficult to diagnose and cause visual loss if delayed. It consists of 5 stages and causes irreversible vision loss with severe complications after stage 2. In this report, photodiagnosis and combined treatment are defined in a Turkish patient with IRVAN syndrome during 6 months of follow-up. Fundus fluorescein angiography (FFA) showed that bilateral aneurysms in retinal vessels as well as aneurysms and ischemic regions were observed in the inferotemporal retina of the left eye. Argon laser photocoagulation was performed to ischemic regions at the left eye. 2 months later best corrected visual acuities were 20/20 and counting fingers from 1 m in the right and left eyes, respectively. Fundus and OCT images showed that an increase in exudations was observed at the left eye and intravitreal injection of dexametasone implant was considered. Three months after initial presentation, best corrected visual acuities were 20/20 and counting fingers from 2 m in right and left eyes, consequetively. In the last fundus and OCT images, the exudations decreased and disappeared on left eye. In this patient, we could not detect an increase in vision due to damage of photoreceptor cells because of subretinal exudation. In the shed-light of this case, the combination therapy seems to improved the anatomical and functional outcomes in IRVAN syndrome however close follow-up and frequent examinations should be prioritized.

RESUMO

Objective: To identify the proportion of eyes with recurrence of diabetic macular edema, six months after focal photocoagulation. Method: Non-experimental, analytical, cross-sectional and prospective study in patients with diabetic macular edema treated with focal photocoagulation. The proportion and 95% confidence intervals (95% CI) of eyes with recurrence of edema were identified; the distribution of anatomical variables and visual acuity was compared between eyes with and without recurrence, using Mann-Whitney's U. Results: 145 eyes were evaluated, and only 10 (95%CI: 2.8-11) had a recurrence. Center point thickness and center field thickness means were higher in eyes with recurrence than in eyes without it, but the difference of change mean betwwen groups was not statistically significant. Conclusion: The proportion of recurrent diabetic macular edema recurrence six months after successful focal photocoagulation was lower than the one reported for other treatments of diabetic macular edema, and by recent studies that used photocoagulation.

RESUMO

La oclusión combinada de arteria y vena central de la retina es poco común en adultos y aún más rara en pacientes jóvenes, siendo las vasculitis y los trastornos tromboembólicos las principales etiologías identificadas. La mayoría de los pacientes tiene un pronóstico sombrío debido al inevitable desarrollo de pérdida visual irreversible y glaucoma neovascular (GNV). Presentamos el caso de un paciente de 14 años de edad que acudió aquejando pérdida visual súbita e indolora en el ojo izquierdo. La mejor agudeza visual corregida fue de percepción de luz, mostrando una exploración oftalmológica y fluorangiográfica característica de oclusión mixta de arteria y vena central de la retina del ojo izquierdo. Las alteraciones encontradas en la exploración física y en los estudios de laboratorio permitieron el diagnóstico de lupus eritematoso sistémico (LES) y síndrome antifosfolípidos. El paciente recibió tratamiento con esteroides y anticoagulante por vía oral, presentando hemorragia vítrea 7 días después debido a tiempos de coagulación prolongados. Para prevenir la aparición de GNV, se inició tratamiento con ranibizumab intravítreo y posteriormente se realizó vitrectomía y endofotocoagulación retiniana. De acuerdo con nuestro conocimiento, este es el primer caso de un paciente masculino pediátrico con LES y oclusión mixta publicado en la literatura, y a su vez el primer caso tratado con antiangiogénicos que no ha desarrollado GNV a 12 meses de seguimiento


Combined central retinal artery and vein occlusion is uncommon in adults and even more so in young people. The main origins are vasculitis and thromboembolic disorders. The prognosis is poor due to irreversible visual loss and the development of neovascular glaucoma (NVG). A 14 year-old male arrived at the clinic complaining of sudden and painless visual loss in the left eye. Best corrected visual acuity was light perception with clinical and fluoro-angiographic findings characteristic of combined central retinal artery and vein occlusion in his left eye. The findings in the systemic and laboratory studies led to a diagnosis of systemic lupus erythematosus (SLE) and antiphospholipid syndrome. The patient received treatment with steroids and oral anticoagulant. Seven days later, due to prolonged coagulation time, he presented with a vitreous haemorrhage. He was then treated with intravitreal ranibizumab in order to prevent NVG. Afterwards, vitrectomy and retinal endophotocoagulation were performed. To the best of our knowledge, this is the first presentation of a male, paediatric with SLE and combined occlusion to be published in the literature, and is also the first case treated with antiangiogenic agents that has not developed NVG at 12 months of follow-up

RESUMO

BACKGROUND/AIMS: To characterise neuroretinal atrophy in retinal vein occlusion (RVO). METHODS: We included patients with central/branch RVO (CRVO=196, BRVO=107) who received ranibizumab according to a standardised protocol for 6 months. Retinal atrophy was defined as the presence of an area of retinal thickness (RT) <260 µm outside the foveal centre. Moreover, the thickness of three distinct retinal layer compartments was computed as follows: (1) retinal nerve fibre layer to ganglion cell layer, (2) inner plexiform layer (IPL) to outer nuclear layer (ONL) and (3) inner segment/outer segment junction to retinal pigment epithelium. To characterise atrophy further, we assessed perfusion status on fluorescein angiography and best-corrected visual acuity (BCVA), and compared these between eyes with/without atrophy. RESULTS: 23 patients with CRVO and 11 patients with BRVO demonstrated retinal atrophy, presenting as sharply demarcated retinal thinning confined to a macular quadrant. The mean RT in the atrophic quadrant at month 6 was 249±26 µm (CRVO) and 244±29 µm (BRVO). Individual layer analysis revealed pronounced thinning in the IPL to ONL compartment. Change in BCVA at 6 months was similar between the groups (BRVO, +15 vs +18 letters; CRVO, +14 vs +18 letters). CONCLUSIONS: In this exploratory analysis, we describe the characteristics of neuroretinal atrophy in RVO eyes with resolved macular oedema after ranibizumab therapy. Our analysis shows significant, predominantly retinal thinning in the IPL to ONL compartment in focal macular areas in 11% of patients with RVO. Eyes with retinal atrophy did not show poorer BCVA outcomes.

RESUMO

Diabetic macular oedema (DMO) is a common complication of diabetic retinopathy and may lead to severe visual loss. In this review, we describe the pathophysiology of DMO and review current therapeutic options such as macular laser photocoagulation, anti-vascular endothelial growth factor agents, and steroid implants with a focus on the new fluocinolone acetonide implant, ILUVIEN®. The results of the Fluocinolone Acetonide in Diabetic Macular Edema (FAME) studies are also presented together with the results of real-world studies to support the clinical use of ILUVIEN® in achieving efficient resolution of DMO and improving vision and macular anatomy in this challenging group of patients.

RESUMO

A female patient presented with stable chronic thrombocytopaenia with large platelets, sensorineuronal deafness and renal impairment. Her treatment was refractory to intravenous immunoglobulins (IVIG) and steroids for a putative diagnosis of immune thrombocytopaenic purpura (ITP). She underwent genetic testing which revealed a MYH9 mutation in-keeping with a diagnosis of Epstein Syndrome. Subsequently to this she developed globally constricted fields on Goldmann visual field testing. MRI pituitary was unremarkable but she was diagnosed with a pituitary microprolactinoma secondary to raised prolactin in the blood responsive to carbegoline therapy. She subsequently developed retinal haemorrhages and recurrent vitreous haemorrhages due to neovascularisation. Fluorescein angiography revealed the extent of the neovascularisation and microvascular ischaemia. She underwent pan-retinal photocoagulation (PRP) to treat the ischaemic stimulus which resulted in regression of the new vessels and cessation of vitreous haemorrhages. There are no previous reported cases of microvascular retinal disease in the literature in the context of Epstein Syndrome, and this is the first report of successful treatment with PRP.

RESUMO

BACKGROUND: Age-related macular degeneration (AMD) is the third largest cause of blindness worldwide, accounting for 8.7% of all cases. A considerable number of preventive or therapeutic interventions have been used for AMD. OBJECTIVE: This study presents a critical view of the interventions that have been assessed through Cochrane systematic reviews. DESIGN AND SETTING: Review of systematic reviews, conducted in the Discipline of Evidence-Based Medicine, Escola Paulista de Medicina (EPM), Universidade Federal de São Paulo (UNIFESP). METHODS: Review of Cochrane systematic reviews about interventions for AMD. RESULTS: The 18 systematic reviews included assessed the effects of surgical techniques, laser/photo/radiotherapy, intravitreal injections, systemic drugs and phytotherapy/vitamins/supplements. CONCLUSION: The Cochrane systematic reviews found evidence that use of bevacizumab, ranibizumab, pegaptanib, laser photocoagulation, photodynamic therapy and multivitamin compounds may present some benefits for treating AMD. There was insufficient evidence for supporting the use of macular translocation, submacular surgery, steroid implantation, radiotherapy, intravitreal aflibercept, interferon alfa, statins or omega-3 fatty acids for treating AMD; or the use of multivitamin antioxidant vitamins or mineral supplementation for preventing AMD. Future randomized controlled trials are imperative to reduce the uncertainty in several clinical questions regarding AMD.

RESUMO

RATIONALE: Report a case of bilateral multiple retinal hamartomas (RAHs) in a patient with tuberous sclerosis complex (TSC) and introduced a new method (subthreshold micropulse laser photocoagulation) for the treatment of RAHs. PATIENT CONCERNS: A 20-year-old man with TSC complained of decreased vision and metamorphosia in both eyes for 2 months. At presentation, visual acuity (VA) was 20/32 in the right eye and 20/40 in the left eye. Fundus photographs, optical coherence tomography, fundus fluorescein angiography (FFA), and indocyanine green angiography indicated multiple RAHs in both eyes. DIAGNOSES: Bilateral retinal astrocytic hamartomas. INTERVENTIONS: In the right eye, 577 nm photocoagulation was adopted to treat the RAHs with obvious fluorescein leakage in FFA. The paramacular RAHs were treated by subthreshold micropulse mode to minimize the damage to macula. Photocoagulation therapy was administrated in the left eye after 1 dose of intravitreal ranibizumab treatment. OUTCOMES: After photocoagulation therapy (including subthreshold micropulse laser photocoagulation for the paramacular RAHs in both eyes), the VA improved to 20/25 OD and 20/32 OS with no recurrence of exudation. LESSONS: About 577 nm photocoagulation for the peripheral RAHs in combination with subthreshold micropulse laser photocoagulation for RAHs in the macular zone is a good option for multiple RAHs in patients with TSC.

RESUMO

Introdução: As patologias vasculares acometem com alta incidência as regiões de cabeça e pescoço. Quando essas acometem a região oral, nota-se predileção por lábios, língua e comissura bucal, com predominância no sexo feminino. Objetivo: Analisar sobre as lesões vasculares orais, enfatizando as características clínicas, métodos de diagnósticos e abordagem terapêutica. Métodos: Trata-se de uma revisão literária, com busca bibliográfica, realizada nas bases de dados eletrônicos PubMED/Medline, Lilacs, Science Direct e SciELO (Scientific Eletronic Library), utilizando os descritores: Hemangioma, Malformações vasculares, escleroterapia e fotocoagulação, em português, inglês e espanhol, obtendo 262 artigos completos, dos quais 18 foram utilizados como base científica apropriada para tal tema, obedecendo aos critérios de inclusão e exclusão. Resultados: As lesões vasculares orais caracterizam-se clinicamente como lesões únicas do tipo nódular ou mancha, cuja coloração varia do vermelho intenso ao roxo e de tamanho variável. Para diagnosticar essas lesões, utilizam-se comumente exames clínicos associados à diascopia, sem na maioria dos casos necessitarem de exames complementares. A intervenção terapêutica justifica-se devido às deformidades estéticas, possíveis sangramentos, ulcerações e infecções. Para tais alterações, existem diversas modalidades terapêuticas, incluindo escleroterapia, crioterapia, remoção cirúrgica e terapia de fotocoagulação a laser. Conclusão: As lesões vasculares orais exibem caracteristicas clinicas peculiares, apresentando-se como nódulos ou manchas, cuja coloração varia do vermelho intenso ao roxo. A diascopia é a manobra semiotécnica mais utilizada e confiável para o estabelecimento do diagnóstico clínico dessas lesões. A utilização de soluções esclerosantes apresenta-se como o tratamento mais descrito na literatura, seguido da fotocoagulação a laser(AU)

Introduction: Vascular disorders affect the head and neck regions with high incidence. When they affect the oral region, there is a predilection for lips, tongue and mouth commissure, predominantly in the female. Objective: To analyze oral vascular lesions, emphasizing the clinical characteristics, diagnostic methods and therapeutic approach. Methods: A bibliographic review was carried out in the databases PubMED/Medline, Lilacs, Science Direct andSciELO (Scientific Electronic Library). We used the descriptors hemangioma, vascular malformations, sclerotherapy and photocoagulation, in Portuguese, English and Spanish. We obtained 262 complete articles, of which 18 were used as appropriate scientific basis for this topic, based on the inclusion and exclusion criteria. Results: Oral vascular lesions are clinically characterized as single lesions of the nodes or blotches, whose color varies from deep red to purple and are of variable size. In order to diagnose these lesions, clinical examinations associated with the periodontal disease are commonly used, although in most cases they do not require complementary examinations. The therapeutic intervention is justified due to aesthetic deformities, possible bleeding, ulcerations and infections. For such changes, there are several therapeutic modalities, including sclerotherapy, cryotherapy, surgical removal and laser photocoagulation therapy. Conclusions: Oral vascular lesions show peculiar clinical characteristics, presenting as nodules or spots, whose coloration varies from intense red to purple. Diascopy is the most used and reliable semi-technical method for establishing the clinical diagnosis of these lesions. The use of sclerosing solutions is the most described treatment in the literature, followed by laser photocoagulation(AU)

We used the descriptors hemangioma, vascular malformations, sclerotherapy and photocoagulation, in Portuguese, English and Spanish. We obtained 262 complete articles, of which 18 were used as appropriate scientific basis for this topic, based on the inclusion and exclusion criteria. Results: Oral vascular lesions are clinically characterized as single lesions of the nodes or blotches, whose color varies from deep red to purple and are of variable size. In order to diagnose these lesions, clinical examinations associated with the periodontal disease are commonly used, although in most cases they do not require complementary examinations. The therapeutic intervention is justified due to aesthetic deformities, possible bleeding, ulcerations and infections. For such changes, there are several therapeutic modalities, including sclerotherapy, cryotherapy, surgical removal and laser photocoagulation therapy. Conclusions: Oral vascular lesions show peculiar clinical characteristics, presenting as nodules or spots, whose coloration varies from intense red to purple. Diascopy is the most used and reliable semi-technical method for establishing the clinical diagnosis of these lesions. The use of sclerosing solutions is the most described treatment in the literature, followed by laser photocoagulation(AU)

RESUMO

Propósito: Comunicar nuestros resultados con la ciclofotocoagulación transescleral con el láser diodo Micropulse(R) (Iridex) en el tratamiento del glaucoma. Métodos: Estudio retrospectivo en pacientes adultos con glaucoma con al menos 6 meses de seguimiento y solo una sesión de Micropulse(R). Se utilizó la misma técnica quirúrgica, el único parámetro de láser que podía variar fue el tiempo total de tratamiento (en segundos). Los parámetros restantes se mantuvieron fijos en 2 W de potencia y 0,5 ms (31,3%) de ciclo activo. Resultados: Se obtuvo un total de 22 ojos de 17 pacientes con glaucoma de diversos tipos y estadios (en su mayoría congénitos y pseudoexfoliativos). El tiempo medio de seguimiento fue 7,9 meses. La duración total del tratamiento varió de 100 a 180 segundos. Definición de éxito: 5 mmHg < presión intraocular (PIO) < 21 mmHg, y una reducción ≥ 20% del valor basal y no adición de inhibidores orales de la anhidrasa carbónica y no reoperación. La tasa de éxito global fue del 72,7% en el primer mes, del 54% a los 4 meses, del 41% a los 6 meses y del 27,3% en el seguimiento final. Los pacientes tratados con duraciones de tratamiento más prolongadas (180 s) lograron mejores resultados. La reducción promedio de la PIO en ojos exitosos fue del 36% (de 26,3 a 16,7 mmHg, DE: 4,58, p = 0,028). No se informaron complicaciones. Conclusiones: En una población heterogénea de glaucoma (principalmente de tipo congénito y pseudoexfoliativo) obtuvimos una baja tasa de éxito (27,3%) en el mediano plazo con una sola sesión de Micropulse(R)

Methods: Retrospective study in adult patients with glaucoma with at least 6 months of follow-up, and only one session of Micropulse (R). The same surgical technique was used in all cases. The only laser parameter that could vary was the total treatment duration (in seconds). The remaining parameters were fixed at 2 Watts of power and 0.5 ms (31.3%) of active cycle. Results: A total of 22 eyes of 17 patients with glaucoma of various types and stages were included (mainly congenital and pseudoexfoliation). The mean follow-up time was 7.9 months. The total treatment duration varied from 100 to 180 seconds. Definition of success: 5 mmHg < Intraocular pressure (IOP) < 21mmHg and a reduction of ≥ 20% of the baseline value and no addition of oral carbonic anhydrase inhibitors, and no re-operation. The overall success rate was 72.7% in the first month, 54% at 4 months, 41% at 6 months, and 27.3% at final follow-up. Patients with longer treatment durations (180 s) achieved better results. The mean reduction in IOP in successful eyes was 36% (from 26.3 to 16.7 mmHg, SD 4.58, P = .028). No complications were reported. Conclusions: In a heterogeneous population of glaucoma (mostly congenital and pseudoexfoliation types), a low success rate (27.3%) was obtained in the medium-term with a single session of Micropulse(R)

RESUMO

Objective: To describe the implementation of a diabetic retinopathy referral network incorporating all levels of health care in La Libertad region, Peru. Method: The nongovernmental organization Orbis International and the Regional Institute of Ophthalmology established a network of primary, secondary and tertiary health-care facilities for diabetic retinopathy screening and treatment. The programme included the provision of three non-mydriatic retinal cameras for patient examination, the development of a flowchart to guide patient referrals, training of health personnel, investment in laser technology for treatment and the delivery of public awareness activities for blindness prevention and the need for timely screening. Findings: From 2014-2017, 11 849 patients with diabetes were screened within the diabetic retinopathy referral network. In primary-care centres, 6012 patients with diabetes mellitus were identified and 5632 patients were referred for diabetic retinopathy screening. A further 4036 patients directly attended two secondary-level hospitals and 2181 attended the tertiary-level hospital for screening. This represented a 138.1% increase in diabetic retinopathy screenings from a baseline of 4977 patients screened at the regional institute of ophthalmology over 2010-2013. A total of 2922 patients (24.7%) were found to have diabetic retinopathy and 923 (31.6%) were treated: 508 with laser photocoagulation, 345 with intravitreal bevacizumab and 70 with vitreoretinal surgery. Conclusion: Effective and timely treatment for diabetic retinopathy is possible when patient education, screening and care are fully integrated into the general health-care system across primary-, secondary- and tertiary-level facilities. This requires the integration of professionals at all levels and all relevant specialties.

RESUMO

The first surgical modalities to reduce aqueous humor production by damaging the ciliary body date back to the early twentieth century. Until recently, however, cyclodestructive procedures (e.g., cyclocryotherapy and transscleral diode laser photocoagulation) have been reserved as last option procedures in refractory glaucoma patients with poor visual potential. Emerging technologic innovation has led to the development of promising, safer and less destructive techniques, such as micropulse diode cyclophotocoagulation, endoscopic cyclophotocoagulation and ultrasound cyclodestruction. Consequently, an emerging paradigm shift is under way with the selection of these surgical options in eyes with less severe glaucoma and good visual potential. Although existing evidence has not, as yet, adequately defined the role and value of these procedures, their emergence is a welcome expansion of available options for patients with moderate-to-severe glaucoma. This article reviews the pertinent evidence on both established and evolving cyclodestructive techniques and describes their growing role in the management of glaucoma.

RESUMO

OBJECTIVE: To compare in daily practice efficacy and safety of standard 180-Watt GreenLight laser photoselective vaporization (PVP) and Thulium laser Vaporesection of the prostate (ThuVEP). MATERIALS AND METHODS: All men were evaluated with prostate volume, prostate-specific antigen, International Prostate Symptom Score, and maximum urinary flow. Patient global impression of improvement was evaluated with patient global impression of improvement scale for 6 months. Antiplatelet/anticoagulant therapy, operation time, 24-hour hemoglobin drop , length of catheterization, discharge day, early complications, and reoperation after 30 days were gathered. Differences between interventions were estimated using propensity scores to adjust for different patients characteristics. The propensity scores were estimated by fitting a stepwise logistic regression model with intervention type as the dependent variable and all the covariates. RESULTS: Five hundred five men underwent the surgical procedures (291 PVP and 214 ThuVEP). Mean age was 69.6 years. Mean prostate volume was 54 mL. Median operation time was 55 minutes. Median catheterization time was 2 days in both series. After matching, the postoperative stay was similar in both groups (2 days). Hemoglobin drop for 24 hours was statistically significantly lower in PVP (-0.5 vs -0.8 g/dL, P .002). Most of the complications were mild-to-moderate and comparable among groups. Δ Maximum urinary flow was similar 6-month after surgery before and after matching, whereas PVP group had a better improvement 12-month after surgery. 96.4% of all patients had an improvement of their symptoms, with no difference between groups, before and after matching. CONCLUSION: Our study demonstrated that PVP and ThuVEP are similar in term of complications and outcomes, with high patients' satisfaction.
