Pachychoroid disease spectrum: review article.

PURPOSE: The aim of this article is to do a comprehensive literature review about the current understandings of the pachychoroid disease spectrum, describing its multimodal imaging analysis, pathophysiology, differential diagnosis, and current types of management. METHODS: This comprehensive literature review was performed based on a search on the PubMed database, of relevant pachychoroid published papers according to our current knowledge. DISCUSSION: The pachychoroid disease spectrum, according to some authors, includes the following: pachychoroid pigment epitheliopathy (PPE), central serous chorioretinopathy (CSC), pachychoroid neovasculopathy (PNV), polypoidal choroidal vasculopathy (PCV)/aneurysmal type 1 neovascularization (AT1), and more recently focal choroidal excavation (FCE) and peripapillary pachychoroid syndrome (PPS). Each one of these entities will be described and discussed in this article. CONCLUSION: Significant advances in multimodal imaging have enabled a better understanding of the typical choroidal changes in pachychoroid disease spectrum. The clinical knowledge and managing options about this disease significantly increased in the last years. However, it is still unclear why some eyes with typical pachychoroid disease phenotype show no evidence of RPE damage and subretinal fluid (uncomplicated pachychoroid) while others present progressive tissue damage, neovascularization, and atrophy.

Variants in HSD11B1 gene modulate susceptibility to diabetes kidney disease and to insulin resistance in type 1 diabetes.

BACKGROUND AND AIM: 11ß-Hydroxysteroid dehydrogenase 1 has been implicated in insulin resistance (IR) in the setting of metabolic disorders, and single nucleotide polymorphisms (SNPs) in its encoding gene (HSD11B1) have been associated with type 2 diabetes and metabolic syndrome. In type 1 diabetes (T1D), IR has been related to the development of chronic complications. We investigated the association of HSD11B1 SNPs with microvascular complications and with IR in a Brazilian cohort of T1D individuals. MATERIALS AND METHODS: Five SNPs were genotyped in 466 T1D individuals (57% women; median of 37 years old, diabetes duration of 25 years and HbA1c of 8.4%). RESULTS: The minor allele T of rs11799643 was nominally associated with diabetic retinopathy (OR = 0.52; confidence interval [CI] 95% = 0.28-0.96; P = .036). The minor allele C of rs17389016 was nominally associated with overt diabetic kidney disease (DKD) (OR = 1.90; CI 95% = 1.07-3.37; P = .028). A follow-up study revealed that 29% of the individuals lost ≥5 mL min-1 × 1.73 m2 per year of the estimated glomerular filtration rate (eGFR). In these individuals (eGFR decliners), C allele of rs17389016 was more frequent than in non-decliners (OR = 2.10; CI 95% = 1.14-3.89; P = .018). Finally, minor allele T of rs846906 associated with higher prevalence of arterial hypertension, higher body mass index and waist circumference, thus conferring risk to a lower estimated glucose disposal rate, a surrogate marker of insulin sensitivity (OR = 1.23; CI 95% = 1.06-1.42; P = .004). CONCLUSION: SNPs in the HSD11B1 gene may confer susceptibility to DKD and to IR in T1D individuals.

Successful Closure of an Idiopathic Macular Hole With Topical Therapy After Failed Surgery.

Purpose: To describe the successful closure of an idiopathic macular hole (MH) with topical therapy after surgery failed. Methods: A case report was evaluated and prospective literature review performed. Results: After surgery to correct an MH in a 57-year-old female patient failed, topical therapy was initiated. MH closure was successful using this modality. Conclusions: There are few reports in the literature describing successful closure of an idiopathic full-thickness MH with topical therapy after initial surgery fails. This reinforces the importance of the "hydration" hole in this disease. Characterization with optical coherence tomography may help determine which patients could benefit from topical treatment for MH closure and avoid costly and invasive surgical procedures.

Rs4862705 in the melatonin receptor 1A gene is associated with renal function decline in type 1 diabetes individuals.

Aim: The pathogenesis of chronic diabetes complications has oxidative stress as one of the major elements, and single-nucleotide polymorphisms (SNPs) in genes belonging to antioxidant pathways modulate susceptibility to these complications. Considering that melatonin is a powerful antioxidant compound, our aim was to explore, in a longitudinal cohort study of type 1 diabetes (T1D) individuals, the association of microvascular complications and SNPs in the gene encoding melatonin receptor 1A (MTNR1A). Methods: Eight SNPs in MTNR1A were genotyped in 489 T1D individuals. Besides cross-sectional analyses of SNPs with each one of the microvascular complications (distal polyneuropathy, cardiovascular autonomic neuropathy, retinopathy, and diabetic kidney disease), a longitudinal analysis evaluated the associations of SNPs with renal function decline in 411 individuals followed up for a median of 8 years. In a subgroup of participants, the association of complications with urinary 6-sulfatoxymelatonin (aMT6s) concentration was investigated. Results: The group of individuals with a renal function decline ≥ 5 mL min-1 1.73 m-2 year-1 presented a higher frequency of the A allele of rs4862705 in comparison with nondecliners, even after adjustment for confounding variables (OR = 1.84, 95% CI = 1.20-2.82; p = 0.0046). No other significant associations were found. Conclusions: This is the first study showing an association between a variant in a gene belonging to the melatonin system and renal function decline in the diabetic setting.

Central retinal artery occlusion secondary to presumed traumatic carotid artery dissection in a healthy child.

PURPOSE: To describe a rare case of a 13 years-old healthy child that presented CRAO secondary to carotid artery dissection, which occurred after a neck rotation movement. METHODS: Case report with prospective literature review. PATIENTS: One patient described in the case report. RESULTS: Not applicable. DISCUSSION/CONCLUSION: Internal carotid artery dissection is a rare condition, specially in children, that can lead to serious cerebral-ocular ischemic events. It may occur due to direct vessel trauma or spontaneously. Prompt imaging screening is of paramount importance because early antithrombotic treatment or surgical intervention may significantly reduce the incidence of devastating ischemic events, such as stroke or central retinal artery occlusion.

Enlightening new underpinnings in hydration retinal folds.

PURPOSE: To describe and value a peculiar alteration typically found in rhegmatogenous retinal detachment raising news foundations of its role in the photoreceptors and visual prognosis. DESIGN: Case description and rationale formulation. SUBJECTS: An isolated case. INTERVENTION: We report a case of a 52-year-old male patient complaining of sudden visual acuity (VA) loss in the left eye. Fundoscopic findings revealed rhegmatogenous retinal detachment, macula off, and an isolated horseshoe tear in the infero-temporal periphery. Spectral-domain optical coherence tomography (SD-OCT) evinced prominent hydration retinal folds. MAIN OUTCOME MEASURES: Restructuring of the retinal layers, visual acuity and complaints. RESULTS: The patient underwent scleral buckling surgery with complete re-attachment of the retina and significant improvement of the hydration retinal folds. In addition, there was resolution of visual symptoms, with a final VA of 20/30. CONCLUSIONS: We speculate that the increase in arc length of the outer retina generates a centripetal force towards the fovea. Its association with the higher density of photoreceptors in this region, generates resistance in the water inflow, preventing swelling and cellular damage of the central photoreceptors.

Pain Perception of Patients Undergoing Laser Panretinal Photocoagulation: Comparison of Single-Spot Versus Multispot Techniques.

BACKGROUND AND OBJECTIVE: To compare pain intensity with single-spot versus multispot technique in laser panretinal photocoagulation, using a 532-nm, solid-state laser system. MATERIALS AND METHODS: This was a prospective, interventional, randomized, single-masked comparison trial. Patients received two types of intervention: conventional single-spot technique, with an exposure time of 150 ms, and multispot technique, done with an exposure time of 20 ms, Both techniques used power sufficient to produce visible gray-white burns, and spot size of 20 µm. Participants received both treatments in the same eye, each one in one hemiretina, and were randomized to receive first single- or multispot technique and to the initial site of treatment. We assessed pain intensity using a numerical pain scale immediately after completion of each treatment. RESULTS: A significantly lower pain scale was observed with the multispot when compared with the single-spot technique (coefficient [Coef]: -1.61; 95% CI, -2.49 to -0.74; P < .001), which was not affected by treatment order, the hemiretina treated, or treatment duration (P > .05). Among demographic characteristics, multiracial patients had a pain scale 1.25 greater than that of White patients (Coef: 1.25; 95% CI, 0.47 to 2.04; P = .002), but there is no effect of age or sex on the pain scale (P > .05). Regarding treatment duration, a shorter procedure was also observed in the multispot technique (Coef: -1.13; 95% CI, -1.43 to -0.82; P < .001), and it was not affected by order of treatment (P = .098), hemiretina (P = .327), pain (P = .141), or demographic data, such as age, sex, and race (P > .05). CONCLUSION: The use of the multispot technique, with a short pulse duration (20 ms), is significantly less painful and less time-consuming for patients with proliferative retinopathy compared with the conventional single-spot technique using an exposure time of 150 ms.

Large inferior retinectomies for proliferative vitreoretinopathy in silicone oil-filled eyes.

BACKGROUND: To describe the anatomical and functional outcomes and late complications in patients who developed inferior proliferative vitreoretinopathy (PVR) in silicone oil-filled eyes and who required reoperation with large inferior retinectomy. METHODS: This is a single-center, retrospective, interventional case series analysis. The study involved 18 individuals with tractional retinal re-detachment due to PVR development inferiorly in eyes who had undergone prior pars plana vitrectomy and silicone oil as a tamponade. All patients included in the study underwent secondary surgery with large inferior retinectomy (from 120° to 270°) and silicone oil filling. RESULTS: The mean follow-up period was 44.0 ± 31.5 (± SD) months (range: 4 to 96 months. The anatomical success, defined as the complete reattachment of the retina until the last follow-up, was observed in 88.9% of the cases. The postoperative visual acuity ranged from 20/100 to hand motion at 60 cm. Only two cases (11.1%) did not achieve anatomical success at the last follow-up due to recurrent PVR and retinal re-detachment (one including hypotony). All of the patients were pseudophakic. The PVR grade, as well as the presence of PVR prior to primary surgery, showed no statistical correlation with BCVA, the extent of retinectomies, and final macular status. There was a statistically significant correlation between "Final BCVA" and "Initial BCVA" (r = 0.654) and between "Final BCVA" and "Extent of Retinectomy" (r = 0.615). CONCLUSIONS: Reoperation in eyes filled with silicone oil may be required when PVR is developed. Secondary surgery in these cases with large inferior retinectomy and silicone oil implantation may reach good anatomical success with low rates of late complications, besides improving visual acuity. A better BCVA at the time of re-RD diagnosis and cases of retinectomies with greater extensions showed a positive correlation with better functional outcomes. Trial registration Research Ethics Committee of the Suel Abujamra Institute reviewed and approved this study protocol (approval number, 5.404.961).

Fingerprint sign in Vogt-Koyanagi-Harada disease: a case series.

BACKGROUND: The tomographic finding, which has been called the "fingerprint sign" in en face reconstructions, seems to be the result of a variety of processes that cause distension of the outer plexiform layer (OPL) and the Henle fiber layer (HFL). The aim of this paper is to describe the appearance of concentric rings at the OPL/HFL interface visualized using en face reconstructions of cross-sectional optical coherence tomography images of patients with Vogt-Koyanagi-Harada disease. METHODS: Retrospective analysis of images of six eyes of three patients obtained by cross-sectional OCT imaging and en face reconstruction at the level of the OPL/HFL interface. RESULTS: All eyes presented with a dentate or saw-tooth pattern of the OPL/HFL interface on cross-sectional OCT with corresponding concentric rings on en face OCT reconstruction, consistent with the recently published "fingerprint sign". Initial OPL/HFL interface changes were observed between the first and fourth months after treatment and resolution of VKHD associated serous retinal detachments. These OPL/HFL interface changes have persisted for many years following the resolution of the active inflammation. CONCLUSIONS: Changes in the OPL/HFL interface can be identified following successful treatment of VKHD. These included both a dentate or saw-tooth pattern on cross-sectional imaging and concentric rings or the "fingerprint sign" on en face reconstructions. These changes persisted for many years despite disease quiescence.

Allelic variations in genes belonging to glutathione system increase proliferative retinopathy risk in type 1 diabetes individuals.

AIMS: Given the participation of oxidative stress in the pathogenesis of diabetic complications, we evaluated, in type 1 diabetes (T1D) individuals, the association between diabetic retinopathy (DR) and functional single nucleotide polymorphisms (SNPs) in regulatory regions of two genes belonging to the antioxidant glutathione (GSH) system: rs17883901 in GCLC and rs713041 in GPX4. METHODS: A cross-sectional case-control study included 288 individuals (61% women, 34[±11] years old, diabetes duration of 22[±9] years, mean [±SD]) sorted according to DR stages: absence of DR (ADR), non-proliferative DR (NPDR) and proliferative DR (PDR). SNPs were genotyped by real-time PCR using fluorescent labelled probes. Logistic regression models with adjustment for confounding covariates were employed. RESULTS: The presence of at least one T-allele of rs17883901 in GCLC was an independent risk factor for PDR (OR 4.13, 95% CI 1.38-13.66, p = 0.014) in a polytomous regression model (PDR versus ADR). The presence of at least one T-allele of rs713041 in GPX4 conferred protection against PDR (OR 0.30, 95% CI 0.11-0.80, p = 0.017) in female T1D individuals. CONCLUSION: The functional SNPs rs17883901 and rs713041 modulate the risk for PDR in the studied population of T1D individuals, widening the spectrum of candidate genes for this complication.

Genetic variants in DNMT1 and the risk of cardiac autonomic neuropathy in women with type 1 diabetes.

AIMS/INTRODUCTION: Epigenetics participate in the pathogenesis of metabolic memory, a situation in which hyperglycemia exerts prolonged deleterious effects even after its normalization. We tested the hypothesis that genetic variants in an epigenetic gene could predispose to diabetes complications. MATERIAL AND METHODS: We assessed the frequency of five single-nucleotide polymorphisms in the gene encoding deoxyribonucleic acid methytransferase 1 (DNMT1; rs8112895, rs7254567, rs11085721, rs17291414 and rs10854076), and their associations with diabetic kidney disease, retinopathy, distal polyneuropathy and autonomic cardiovascular neuropathy in 359 individuals with long-term type 1 diabetes. RESULTS: None of the single-nucleotide polymorphisms studied was significantly associated with the presence of chronic complications in the overall population. However, after sex stratification, the minor allele C of rs11085721 conferred risk for cardiovascular neuropathy in women after adjustment for confounding variables (odds ratio 2.32; 95% confidence interval 1.26-4.33; P = 0.006). CONCLUSIONS: The fact that heterozygous mutations in DNMT1 are associated with hereditary sensory autonomic neuropathy provides plausibility to the present finding. If confirmed in independent samples, it suggests that genetic variants in epigenetic genes might predispose to more or fewer epigenetic changes in the face of similar metabolic derangements triggered by hyperglycemia, constituting the "genetics of epigenetics" for microvascular diabetes complications.

Thioredoxin interacting protein expression in the urinary sediment associates with renal function decline in type 1 diabetes.

AIMS: Thioredoxin interacting protein (TXNIP), an inhibitor of antioxidant thioredoxin (Trx), is upregulated by hyperglycemia and implicated in pathogenesis of diabetes complications. We evaluated mRNA expressions of genes encoding TXNIP and Trx (TXN) in urinary sediment and peripheral blood mononuclear cells (PBMC) of type 1 diabetes (T1D) patients with different degrees of chronic complications. METHODS: qPCR was employed to quantify target genes in urinary sediment (n = 55) and PBMC (n = 161) from patients sorted by presence or absence of diabetic nephropathy (DN), retinopathy, peripheral and cardiovascular neuropathy; 26 healthy controls and 13 patients presenting non-diabetic nephropathy (focal and segmental glomerulosclerosis, FSGS) were also included. RESULTS: Regarding the urinary sediment, TXNIP (but not TXN) expression was higher in T1D (p = 0.0023) and FSGS (p = 0.0027) patients versus controls. Expressions of TXNIP and TXN were higher, respectively, in T1D patients with versus without DN (p = 0.032) and in those with estimated glomerular filtration rate (eGFR) < 60 versus ≥60 mL/min/1.73 m(2) (p = 0.008). eGFR negatively correlated with TXNIP (p = 0.04, r = -0.28) and TXN (p = 0.04, r = -0.30) expressions. T1D patients who lost ≥5 mL/min/1.73 m(2) yearly of eGFR presented higher basal TXNIP expression than those who lost <5 mL/min/1.73 m(2) yearly after median follow-up of 24 months. TXNIP (p < 0.0001) and TXN (p = 0.002) expressions in PBMC of T1D patients were significantly higher than in controls but no differences were observed between patients with or without chronic complications. CONCLUSIONS: TXNIP and TXN are upregulated in urinary sediment of T1D patients with diabetic kidney disease (DKD), but only TXNIP expression is associated with magnitude of eGFR decline.

Single intravitreal bevacizumab injection effects on contrast sensitivity in macular edema from branch retinal vein occlusion.

PURPOSE: To evaluate the effect of a single intravitreal bevacizumab injection on visual acuity, contrast sensitivity and optical coherence tomography-measured central macular thickness in eyes with macular edema from branch retinal vein occlusion. METHODS: Seventeen eyes of 17 patients with macular edema from unilateral branch retinal vein occlusion were treated with a single bevacizumab injection. Patients were submitted to a complete evaluation including best corrected visual acuity, contrast sensitivity and optical coherence tomography measurements before treatment and one and three months after injection. Visual acuity, contrast sensitivity and optical coherence tomography measurements were compared to baseline values. RESULTS: Mean visual acuity measurement improved from 0.77 logMAR at baseline to 0.613 logMAR one month after injection (P=0.0001) but worsened to 0.75 logMAR after three months. Contrast sensitivity test demonstrated significant improvement at spatial frequencies of 3, 6, 12 and 18 cycles/degree one month after injection and at the spatial frequency of 12 cycles/degree three months after treatment. Mean ± standard deviation baseline central macular thickness (552 ± 150 µm) reduced significantly one month (322 ± 127 µm, P=0.0001) and three months (439 ± 179 µm, P=0.01) after treatment. CONCLUSIONS: Bevacizumab injection improves visual acuity and contrast sensitivity and reduces central macular thickness one month after treatment. Visual acuity returns to baseline levels at the 3-month follow-up, but some beneficial effect of the treatment is still present at that time, as evidenced by optical coherence tomography-measured central macular thickness and contrast sensitivity measurements.

Prophylaxis and treatment of cystoid macular edema after cataract surgery / Profilaxia e tratamento do edema macular cistoide após cirurgia de catarata

Macular cystoid edema is one of the major causes of decreased vision after cataract surgery. The inflammatory process appears to be the main causal factor of the edema. The major risk factors are: surgical complications, previous retinal diseases, diabetes, uveitis and use of prostaglandins drops. The diagnosis is clinically, but fluorescein angiography and optical coherence tomography are also important to detect swelling and assist in differential diagnosis. Although pre-operative prophylaxis do not have scientific evidence, it is recommended especially in cases with risk factors. The initial treatment includes a combination of both topic corticosteroid and nonsteroidal anti-inflammatory. Chronic and refractory cases can be managed with alternatives treatment, such as intravitreal triamcinolone and anti-angiogenic. This article aims to discuss various aspects of pseudophakic macular cystoid edema.

O edema macular cistoide é uma das principais causas de baixa de visão após cirurgia de catarata. O processo inflamatório parece ser o principal fator causal do edema. São considerados fatores de risco complicações cirúrgicas, doenças retinianas prévias, diabetes, uveítes e uso de colírios de prostaglandinas. O diagnóstico é feito clinicamente, mas a angiografia fluoresceínica e a tomografia de coerência óptica também são ferramentas importantes para detectar o edema e auxiliar no diagnóstico diferencial. Apesar da profilaxia pré-operatória não ter evidência científica, ela é preconizada especialmente nos casos com fatores de risco. O tratamento inicial é realizado com associação de corticoide e anti-inflamatório não hormonais tópicos. Os casos crônicos e refratários têm diversas alternativas de tratamento, sendo o uso de triancinolona e antiangiogênicos intravítreos as mais utilizadas. Este artigo se propõe a discutir diversos aspectos do edema macular cistoide pseudofácico.

OBJETIVO: Avaliar o efeito de uma única injeção intravítrea de bevacizumabe na função visual, sensibilidade ao contraste, em olhos com edema macular causado por oclusão de ramo venoso retiniano. MÉTODOS: Dezessete olhos de 17 pacientes com edema macular unilateral causado por oclusão de ramo venoso retiniano foram tratados com uma única injeção intravítrea de bevacizumabe. Pacientes previamente foram submetidos a exame ocular completo, sensibilidade ao contraste, variável de maior interesse, melhor acuidade visual corrigida e tomografia de coerência óptica e foram reavaliados no 1º e 3º mês de seguimento. RESULTADOS: O teste de sensibilidade ao contraste demonstrou melhora significante nas frequências espaciais 3, 6, 12 e 18 ciclos/grau (c/g) no primeiro mês de seguimento e na frequência espacial 12 c/g após o 3º mês de tratamento. A média da acuidade visual melhorou de 0,77 no pré-tratamento para 0,61 logMAR no 1º mês de seguimento (P=0,0001), com piora ao final do 3º mês, 0,75 logMAR. A média da espessura foveal central (552 ± 150 µm) reduziu significantemente no 1º (322 ± 127 µm, P=0,0001) e 3º (439 ± 179 µm, P=0,01) mês de seguimento. CONCLUSÃO: No edema macular causado por oclusão de ramo venoso retiniano, uma única injeção intravítrea de bevacizumabe melhora a sensibilidade ao contraste, acuidade visual e reduz a espessura foveal central após 1 mês de tratamento. Após 3 meses de seguimento, ainda é possível observar benefício com o tratamento, como foi evidenciado pela sensibilidade ao contraste e a medida da espessura foveal central à tomografia de coerência óptica.

Crises glaucomatociclíticas: relato de seis casos / Glaucomatocyclitic crisis: six cases report

Esse trabalho apresenta seis pacientes portadores de crises glaucomatociclíticas. Cada paciente apresentou crises recorrentes e unilaterais de elevaçäo aguda da PIO associada a discreta ciclite. os sintomas em cada crise foram desproporcionalmente pequenos para os níveis pressóricos medidos e os sinais congestivos eram discretos. A duraçäo de cada crise variou de dois dias a três semanas e todos os episódios responderam a medicaçäo antiglaucomatosa e antiinflamatória. A despeito das múltiplas crises os pacientes näo desenvolveram defeitos de campo visual e a escavaçäo do disco óptico aumentou em apenas dois pacientes. Num destes foi documentada a associaçäo com glaucoma crônicodddddd simples. Uma particularidade observada foi a presença de dois alcoólatras na casuística sendo que um referia que suas crises eram desencadeadas por grandes ingestöes alcoólicas. Foi utilizada em alguns pacientes a profilaxia com indometacina ou tropicamida tópica, mas a efetividade dessas drogas em prevenir novas crises foi duvidosa.

Ferimentos perfurantes oculares no Hospital das Clínicas da Faculdade de Medicina da Universidade de Säo Paulo. O que mudou nos últimos 27 anos / Ocular penetrating wounds in the Hospital das Clínicas of the University of Säo Paulo. The changes in the last 27 years

Foi realizado um estudo retrospectivo de 95 olhos de 92 pacientes com ferimento perfurante ocular admitidos na Clínica Oftalmológica do Hospital das Clínicas da FMUSP entre maio de 1996 a março de 1997.77.2 por cento dos pacientes eram do sexo masculino, a faixa etária mais acometida foi de zero a 40 anos (85.9 por cento). O principal agente causador foi o acidente automobilístico(29.5 por cento), seguido pelos acidentes domésticos, pelos ferimentos causados pela violência e pelos acidentes de trabalho(22.1 por cento,22.1 por cento e 20 por cento respectivamente). Medidas preventivas parecem ter modificado pouco o perfil das causas desses ferimentos no nosso serviço nas últimas décadas, embora sua incidência total tenha diminuído nos últimos cinco anos.
