Abstract
Despite advances in systemic care, diabetic disease of the eye (DDE) remains the leading cause of blindness worldwide. There is a critical gap of up-to-date, evidence-based guidance for ophthalmologists in Canada that includes evidence from recent randomized controlled trials. Previous guidance has not always given special consideration to applying treatments and managing DDE in the context of the healthcare system. This consensus statement aims to assist practitioners in the field by providing a spectrum of acceptable opinions on DDE treatment and management from recognized experts in the field. In compiling evidence and generating consensus, a working group of retinal specialists in Canada addressed clinical questions surrounding the four themes of disease, patient, management, and collaboration. The working group reviewed literature representing the highest level of evidence on DDE and shared their opinions on topics surrounding the epidemiology and pathophysiology of diabetic retinopathy and diabetic macular edema; diagnosis and monitoring; considerations around diabetes medication use; strategic considerations for management given systemic comorbidities, ocular comorbidities, and pregnancy; treatment goals and modalities for diabetic macular edema, non-proliferative and proliferative diabetic retinopathy, and retinal detachment; and interdisciplinary collaboration. Ultimately, this work highlighted that the retinal examination in DDE not only informs the treating ophthalmologist but can serve as a global index for disease progression across many tissues of the body. It highlighted further that DDE can be treated regardless of diabetic control, that a systemic approach to patient care will result in the best health outcomes, and prevention of visual complications requires a multidisciplinary management approach. Ophthalmologists must tailor their clinical approach to the needs and circumstances of individual patients and work within the realities of their healthcare setting.

Abstract
INTRODUCTION Anti-vascular endothelial growth factor (anti-VEGF) agents may occasionally need to be considered for sight-threatening macular pathology in pregnant and breastfeeding women. This is controversial due to the dearth of data on systemic side effects for mother and child. We aimed to expand the evidence base to inform management. METHODS Retrospective case series of pregnant and breastfeeding women treated with intravitreal anti-VEGF injections at Oxford Eye Hospital between January 2015 and December 2022. In addition, we conducted a systematic review and combined eligible cases in a narrative synthesis. RESULTS We treated six pregnant women with anti-VEGF for diabetic macular oedema(DMO) (n = 5) or choroidal neovascularisation (CNV) (n = 1). Four received ranibizumab whilst two (not known to be pregnant) received aflibercept. Patients known to be pregnant underwent counselling by an obstetric physician. Five pregnancies resulted in live births. Combining our cases with those previously published, treatment of 41 pregnant women (42 pregnancies) are reported. Indications for treatment included CNV (n = 28/41,68%), DMO (n = 7/41,17%) and proliferative diabetic retinopathy (n = 6/41,15%). Bevacizumab (n = 22/41,54%) and ranibizumab (n = 17/41,41%) were given more frequently than aflibercept (n = 2/41,5%). Many (n = 16/41,40%) were unaware of their pregnancy when treated. Most pregnancies resulted in live births (n = 34/42,81%). First trimester miscarriages (n = 5/42,12%) and stillbirths (n = 3/42,7%) mostly occurred in women with significant risk factors. CONCLUSION Intravitreal anti-VEGF injections may not necessarily compromise obstetric outcomes, although clear associations cannot be drawn due to small numbers and confounders from high rates of first trimester miscarriages in general and inherently high-risk pregnancies. It may be worth considering routinely investigating pregnancy and breastfeeding status in women of childbearing age prior to each injection, as part of anti-VEGF treatment protocols.

Abstract
Diabetic macular edema (DME) is a common complication of diabetes mellitus and a leading cause of visual impairment worldwide. It is defined as the diabetes-related accumulation of fluid, proteins, and lipids, with retinal thickening, within the macular area. DME affects a significant proportion of individuals with diabetes, with the prevalence increasing with disease duration and severity. It is estimated that approximately 25-30% of diabetic patients will develop DME during their lifetime. Poor glycemic control, hypertension, hyperlipidemia, diabetes duration, and genetic predisposition are recognized as risk factors for the development and progression of DME. Although the exact pathophysiology is still not completely understood, it has been demonstrated that chronic hyperglycemia triggers a cascade of biochemical processes, including increased oxidative stress, inflammation, activation of vascular endothelial growth factor (VEGF), cellular dysfunction, and apoptosis, with breakdown of the blood-retinal barriers and fluid accumulation within the macular area. Early diagnosis and appropriate management of DME are crucial for improving visual outcomes. Although the control of systemic risk factors still remains the most important strategy in DME treatment, intravitreal pharmacotherapy with anti-VEGF molecules or steroids is currently considered the first-line approach in DME patients, whereas macular laser photocoagulation and pars plana vitrectomy may be useful in selected cases. Available intravitreal steroids, including triamcinolone acetonide injections and dexamethasone and fluocinolone acetonide implants, exert their therapeutic effect by reducing inflammation, inhibiting VEGF expression, stabilizing the blood-retinal barrier and thus reducing vascular permeability. They have been demonstrated to be effective in reducing macular edema and improving visual outcomes in DME patients but are associated with a high risk of intraocular pressure elevation and cataract development, so their use requires an accurate patient selection. This manuscript aims to provide a comprehensive overview of the pathology, epidemiology, risk factors, physiopathology, clinical features, treatment mechanisms of actions, treatment options, prognosis, and ongoing clinical studies related to the treatment of DME, with particular consideration of intravitreal steroids therapy.

Mesenchymal stem cell secretome ameliorates over-expression of soluble fms-like tyrosine kinase-1 (sFlt-1) and fetal growth restriction (FGR) in animal SLE model. J Matern Fetal Neonatal Med 2023; 36:2279931. [PMID: 37953255 DOI: 10.1080/14767058.2023.2279931] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2023] [Accepted: 10/31/2023] [Indexed: 11/14/2023]
Abstract
INTRODUCTION In the near future, stem cell research may lead to several major therapeutic innovations in medical practice. Secretome, a "by-product" of stem cell line cultures, has many advantages. Its easiness of storage, usage, and fast direct effect are some of those to consider. Fetal growth restriction (FGR) remains one of the significant challenges in maternal-fetal and neonatal medicine. Placentation failure is one of the most profound causal and is often related to increasing sFlt-1 in early pregnancy. This study aimed to investigate hUC-MSC secretome in ameliorating sFlt-1 and how to improve outcomes in preventing FGR in an animal model. MATERIALS AND METHODS Pristane-induced systemic lupus erythematosus (SLE) in a mouse model was used to represent placentation failure and its consequences. Twenty-one mice were randomized into three groups: (I) normal pregnancy, (II) SLE, and (III) SLE with secretome treatment. Pristane was administered in all Groups four weeks prior mating period. Secretome was derived from human umbilical cord mesenchymal stem cells (hUC-MSC) conditioned medium on the 3rd and 4th passage, around day-21 until day-28 from the start of culturing process. Mesenchymal stem cell was characterized using flow cytometry for CD105+, CD90+, and CD73+ surface antigen markers. Immunohistochemistry anlysis by using Remmele's Immunoreactive Score (IRS) was used to quantify the placental sFlt-1 expression in each group. Birth weight and length were analyzed as the secondary outcome. The number of fetuses obtained was also calculated for pregnancy loss comparison between Groups. RESULTS The administration of secretome of hUC-MSC was found to lower the expression of the placental sFlt-1 significantly in the pristane SLE animal model (10.30 ± 1.40 vs. 4.98 ± 2.57; p < 0.001) to a level seen in normal mouse pregnancies in Group I (3.88 ± 0.49; p = 0.159). Secretome also had a significant effect on preventing fetal growth restriction in the pristane SLE mouse model (birth weight: 354.29 ± 80.76 mg vs. 550 ± 64.03 mg; p < 0.001 and birth length: 14.43 ± 1.27 mm vs. 19.00 ± 1.41 mm), comparable to the birth weight and length of the normal pregnancy in Group I (540.29 ± 75.47 mg and 18.14 ± 1.34 mm, p = 0.808 and = 0.719). Secretome administration also showed a potential action to prevent high number of pregnancy loss as the number of fetuses obtained could be similar to those of mice in the normal pregnant Group (7.71 ± 1.11 vs. 7.86 ± 1.06; p = 0.794). CONCLUSIONS Administration of secretome lowers sFlt-1 expression in placenta, improves fetal growth, and prevents pregnancy loss in a mouse SLE model.

[PMID: 37898362 DOI: 10.1016/j.preteyeres.2023.101219] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2023] [Revised: 10/12/2023] [Accepted: 10/13/2023] [Indexed: 10/30/2023]
Abstract
Randomised clinical trials (RCTs) are generally considered the gold-standard for providing scientific evidence for treatments' effectiveness and safety but their findings may not always be generalisable to the broader population treated in routine clinical practice. RCTs include highly selected patient populations that fit specific inclusion and exclusion criteria. Although they may have a lower level of certainty than RCTs on the evidence hierarchy, real-world data (RWD), such as observational studies, registries and databases, provide real-world evidence (RWE) that can complement RCTs. For example, RWE may help satisfy requirements for a new indication of an already approved drug and help us better understand long-term treatment effectiveness, safety and patterns of use in clinical practice. Many countries have set up registries, observational studies and databases containing information on patients with retinal diseases, such as diabetic macular oedema (DMO). These DMO RWD have produced significant clinical evidence in the past decade that has changed the management of DMO. RWD and medico-administrative databases are a useful resource to identify low frequency safety signals. They often have long-term follow-up with a large number of patients and minimal exclusion criteria. We will discuss improvements in healthcare information exchange technologies, such as blockchain technology and FHIR (Fast Healthcare Interoperability Resources), which will connect and extend databases already available. These registries can be linked with existing or emerging retinal imaging modalities using artificial intelligence to aid diagnosis, treatment decisions and provide prognostic information. The results of RCTs and RWE are combined to provide evidence-based guidelines.

Abstract
Pregnancy is a medical condition in which the physiological changes in the maternal body and the potential impact on the developing fetus require a cautious approach in terms of drug administration. Individual treatment, a thorough assessment of the extent of the disease, and a broad knowledge of the therapeutic options and different routes of administration of ophthalmic drugs are essential to ensure the best possible results while minimizing risks. Although there are currently several routes of administration of drugs for the treatment of eye diseases, even with topical administration, there is a certain amount of systemic absorption that must be taken into account. Despite continuous developments and advances in ophthalmic drugs, no updated data are available on their safety profile in these contexts. The purpose of this review is both to summarize the current information on the safety of ophthalmic treatments during pregnancy and lactation and to provide a practical guide to the ophthalmologist for the treatment of eye diseases while minimizing harm to the developing fetus and addressing maternal health needs.

Abstract
INTRODUCTION This study aimed to provide information on modifiable and non-modifiable risk factors for the progression and development of diabetic retinopathy (DR) and diabetic macular edema (DME). This retrospective chart review case-control study was designed to provide perspective on clinical variables. METHODS Single-center study analysis was completed with chart review, identifying 50 patients (100 eyes) ultimately included in the final analysis. Included patients were women with type 1 or 2 diabetes that entered prenatal care and had a delivery from January 2010 to December 2022. The primary outcome measure was clinical variables between progression and no progression groups. Data were analyzed via χ2 analysis and independent samples t test when appropriate. Significantly different variables were further analyzed by binary logistic regression. RESULTS The DR progression group had significantly higher prepregnancy HbA1c levels (9.9) when compared to the no progression group (8.5, p value 0.028). DR progression group also had higher rates (51.9%) of full-term births. The DME progression group had significantly higher rates of type 2 diabetics (100%) compared to the no progression group (30.9%, p value 0.029). Hypertension treatment before (81.8%; p value 0.008) pregnancy was also more common in the DME progression group. Intravitreal injections were more common in patients with visual acuity deterioration (26.7%, p value 0.046). The average number of fetal complications was significantly higher in the visual acuity non-worsening group (1.1) compared to the progression group (0.5, p value 0.04). These variables were not statistically significant after entry into multivariate analysis. DISCUSSION Severity and treatment of retinopathy before pregnancy, type of diabetes, and blood pressure control are all significant factors affecting the progression and development of severe ocular complications in pregnancy.

Abstract
Objectives: Intraocular administration of vascular endothelial growth factor (VEGF) inhibitors may be associated with pregnancy loss. However, little is known about intraocular anti-VEGF therapy during pregnancy. Here, we conducted a pharmacovigilance study using a spontaneous reporting database to evaluate the relationship between intraocular VEGF inhibitors and pregnancy loss. Methods: We used the JAPIC AERS database which is composed of the Food and Drug Administration Adverse Event Reporting System (FAERS) dataset preprocessed by the Japan Pharmaceutical Information Center (JAPIC) to investigate the VEGF inhibitors ranibizumab, aflibercept, and bevacizumab. Disproportionality analyses were conducted for VEGF inhibitors and pregnancy loss. The lower limit of the 95% confidence interval (CI) of the reporting odds ratio (ROR) > 1 and a minimum of three reported cases of pregnancy loss were the detection criteria used in the current study. Results: In the FAERS, 19 pregnancy loss cases were reported for ranibizumab with an ROR of 4.44 (95% CI: 2.42-8.16), 6 for intraocular bevacizumab with an ROR of 32.25 (95% CI: 3.88-267.9), and 4 for intraocular aflibercept with an ROR of 5.37 (95% CI: 1.34-21.49). All these drugs met the detection criteria. Conclusion: Potential safety signals of pregnancy loss were obtained from intraocular administration of VEGF inhibitors during pregnancy. These signals should be validated using a causal design study.

Abstract
BACKGROUND Diabetic retinopathy (DR) is the leading cause of blindness in the working-age population, and it increases in severity during pregnancy. METHODS Systematic review of literature from PubMed, Cochrane Library and Web of Science using keywords 'diabetic retinopathy' and 'pregnancy' and 'progression' from inception to 2021 was completed. Included studies were (1) peer-reviewed observational studies addressing progression/development of DR in pregnancy, (2) provided the number of diabetic patients that developed/progressed in DR during pregnancy, and (3) included differential data on variables between progression and non-progression groups. This was applied by two independent researchers and referred to a third researcher as necessary. Twenty-seven of the original 138 studies met this criterion. Data were pooled and analysed using fixed-effects in meta-analysis. RESULTS From 27 studies, 2537 patients were included. Pre-eclampsia [Risk Ratio (RR) 2.62 (95% CI = 1.72, 4.00)] and hypertension treatment during pregnancy [RR 2.74 (95% CI = 1.72, 4.00)] were significantly associated with the development/progression of DR. HbA1c at baseline [MD 0.82 (95% CI = 0.59, 1.06)], duration of diabetes [mean difference (MD) 5.97 (95% CI = 5.38, 6.57)], and diastolic blood pressure at baseline [MD 3.29 (95% CI = 0.46, 6.12)] were all significantly higher in the progression group while only mean birth weight [MD -0.17 (95% CI = -0.31, -0.03)] was significantly higher in the non-progression group. CONCLUSIONS This study fills a gap in the literature and provide physicians with more information on the risk factors associated with the progression of DR in pregnancy and how to counsel this vulnerable patient population appropriately.

Association between Obstetric Complications and Intravitreal Anti-Vascular Endothelial Growth Factor Agents or Intravitreal Corticosteroids. J Pers Med 2022; 12:jpm12091374. [PMID: 36143159 PMCID: PMC9501719 DOI: 10.3390/jpm12091374] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2022] [Revised: 08/22/2022] [Accepted: 08/23/2022] [Indexed: 11/16/2022] Open
Abstract
This nationwide population-based cohort study aimed to describe the use of intravitreal injections (IVTs) of anti-vascular endothelial growth factor (anti-VEGF) agents and corticosteroids in pregnant women in France and to report on the incidence of obstetric and neonatal complications. All pregnant women in France who received any anti-VEGF or corticosteroid IVT during pregnancy or in the month preceding pregnancy from 1 January 2009 to 31 December 2018 were identified in the national medico-administrative databases. Between 2009 and 2018, there were 5,672,921 IVTs performed in France. Among these IVTs, 228 anti-VEGF or corticosteroid IVTs were administered to 139 women during their pregnancy or in the month preceding their pregnancy. Spontaneous abortion or the medical termination of pregnancy occurred in 10 women (16.1%) who received anti-VEGF agents and in one (3.1%) of the women who received corticosteroids (p = 0.09). This is the first national cohort study of pregnant women treated with anti-VEGF or corticosteroid IVTs. We found a high incidence of obstetric complications in pregnant women treated with anti-VEGF or corticosteroid IVTs but could not demonstrate a statistically significant association between the intravitreal agents and these complications. These agents should continue to be used with great caution in pregnant women.

Transplacental Passage and Fetal Effects of Antineoplastic Treatment during Pregnancy. Cancers (Basel) 2022; 14:cancers14133103.

Abstract
Simple Summary In this paper we perform an introduction about pregnancy-associated cancer (PAC) and transplacental passage of antineoplastic agents. Furthermore, we describe therapeutic use and potential toxic effects of chemotherapeutic drug (alkylating agents, antimetabolites agents, anthracyclines, topoisomerase inhibitors, antimitotic agents, actinomycin-D, bleomycin) and targeted agents during pregnancy. This manuscript may be a useful and practical guide for the management of PAC, which is a challenge for clinicians that have to consider alike maternal benefits and fetal potential risks correlated to the antineoplastic treatment. Abstract The incidence of PAC is relatively infrequent among pregnant women. However, it has gradually increased in recent years, becoming a challenging area for clinicians that should take into account in the same way maternal benefits and fetal potential risks correlated to the antineoplastic treatment. None of the antineoplastic drugs is completely risk-free during the pregnancy, the timing of exposure and transplacental transfer properties influence the toxicity of the fetus. Despite the lack of guidelines about the management of PAC, several studies have described the use and the potential fetal and neonatal adverse events of antineoplastic drugs during pregnancy. We provide a review of the available literature about the transplacental passage and fetal effects of chemotherapy and targeted agents, to guide the clinicians in the most appropriate choices for the management of PAC.

Abstract
Purpose To evaluate the clinical course of idiopathic multifocal choroiditis (MFC) and punctate inner choroidopathy (PIC) and the efficacy and safety of treatment options during pregnancy. Methods Patients with MFC or PIC and a pregnancy in 2011–2019 from two academic centres were enrolled. For the most recent pregnancy, data on best‐corrected visual acuity (BCVA) before and after pregnancy, relapse rate in pregnancy and postpartum period and obstetric, maternal and neonatal outcomes were collected. Treatment regimens consisted of a wait‐and‐see regime and an immunosuppressive treatment regime with systemic corticosteroids and/or azathioprine, both combined with intravitreal antivascular endothelial growth factor injections when indicated. Results Sixteen women (26 affected eyes) were included. Median Snellen BCVA was 20/19 before pregnancy and 20/18 after delivery. In seven pregnancies a wait‐and‐see regime and in nine pregnancies an immunosuppressive treatment regime was carried out. Fourteen intravitreal anti‐VEGF injections were given in six pregnancies. The relapse rate during pregnancy was 44% and in the postpartum period 31%. Maternal/obstetrical and fetal complications occurred in 31% and 13% of the pregnancies, respectively. Fifteen healthy children were born and one pregnancy ended in a stillbirth in a patient with a complicated obstetrical history. One patient treated with azathioprine developed intrahepatic cholestasis of pregnancy (ICP). Conclusions Among women with MFC and PIC BCVA remained stable during pregnancy despite a relapse rate of 44% in pregnancy. No major maternal, obstetric and fetal complications occurred in pregnant patients treated with systemic corticosteroids, azathioprine or intravitreal anti‐VEGF injections, though one patient developed ICP while treated with azathioprine.

Abstract
Objective: The objective of this work was to present two unusual cases of central serous chorioretinopathy (CSC) and the chosen therapeutic method. Materials and methods: In this article, two cases of CSC in pregnant patients were described. Results: The first case was a 35-year-old patient in the 16th week of pregnancy and the second one was a 26-year-old patient in the 20th week of pregnancy. Due to the contraindications associated to pregnancy, the therapeutic method chosen was subthreshold micropulse laser photocoagulation. The functional and anatomical evolution was very good in both patients. Discussion: In both cases, treatment of the disease was preferred to prevent important photoreceptor losses. After the treatment, very good anatomical and functional results were obtained. Conclusions: The micropulse laser is an effective solution for treating CSC. It is the only safe therapeutic solution during pregnancy. CSC can be associated with pregnancy, without necessarily suggesting pre-eclampsia. Abbreviations: CSC = central serous chorioretinopathy, SRF = subretinal fluid.

Abstract
In the modern world, myopia continues to be one of the most common refractive errors and is considered a socially signifi cant problem, since it is a common cause of decreased vision. In connection with the growth of myopia, the risk of developing complications in the fundus increases, leading to the development of degenerative changes in the retina and an irreversible decrease in visual functions in young and middle-aged people. One of these complications is myopic choroidal neovascularization, which leads to a progressive, irreversible decrease in visual acuity and poor prognosis, and the process is often bilateral in nature. The tactics of managing patients with such complications has been determined: antiangiogenic therapy is used – intravitreal therapy with anti-VEGF drugs, which is currently the fi rst choice therapy for this pathology. But in some cases, antiangiogenic therapy is contraindicated, and the question arises about the tactics of managing such patients. The aim: to study treatment options for myopic choroidal neovascularization in patients with myopia in different situations.Material and methods. The paper presents two clinical observations of patients with mChNV, considers the tactics of their management. The patients underwent standard ophthalmological examination, optical coherence tomography (OCT) and OCT-Angio (OPTOPOL Technology, Poland).Conclusions. Women with myopia planning pregnancy need a thorough examination not only by a clinician, but also by an ophthalmologist, since it is necessary to take into account not only the degree of myopia and choose the optimal delivery method, but also to study the state of the retina for the timely diagnosis of degenerative changes in the fundus.

Abstract
Purpose: Intravitreal anti-vascular endothelial growth factor (VEGF) injection therapy has emerged as the mainstay of treatment in the management of diabetic macular edema (DME) today. Various systemic risk factors have to be considered before initiating anti-VEGF therapy. The aim of our study was to form a consensus on various systemic factors to consider before starting anti-VEGF therapy for DME. Methods: A questionnaire was created and sent across to various retina specialists across India. A Google™ form with various questions pertaining to what systemic parameters would one consider before giving anti-VEGF therapy for DME was sent to each of them by email/WhatsApp™/direct telephonic interview. Results: Of the 650 retina specialists contacted, 322 responded to the questionnaire. There was no difference in responses between private and institutional practitioners. The majority would consider RBS (85%), HbA1c (61%), blood pressure (63%), and renal function (57%) as a routine before administering the anti-VEGF injection, while the majority would not consider hemoglobin (63%) or lipid profile (55%) of the patient as a routine practice prior to administering the injection. Conclusion: In our study, most VR specialists prefer to consider RBS, HbA1c, BP, and renal profile (creatinine) routinely prior to anti-VEGF injection. We suggest that it is important to consider blood pressure control, glycemic control, HbA1c, Hb, lipid profile, and renal profile (UACR, eGFR, and creatinine) prior to anti-VEGF therapy in all diabetic patients and to discuss the need for statins in patients with dyslipidemias with the physician.

Abstract
Diabetes mellitus (DM) is a noncommunicable disease reaching epidemic proportions around the world. It affects younger individuals, including women of childbearing age. Diabetes can cause diabetic retinopathy (DR), which is potentially sight threatening when severe nonproliferative DR (NPDR), proliferative DR (PDR), or sight-threatening diabetic macular oedema (STDME) develops. Pregnancy is an independent risk factor for the progression of DR. Baseline DR at the onset of pregnancy is an important indicator of progression, with up to 10% of women with baseline NPDR progressing to PDR. Progression to sight-threatening DR (STDR) during pregnancy causes distress to the patient and often necessitates ocular treatment, which may have a systemic effect. Management includes prepregnancy counselling and, when possible, conventional treatment prior to pregnancy. During pregnancy, closer follow-up is required for those with a long duration of DM, poor baseline control of blood sugar and blood pressure, and worse DR, as these are risk factors for progression to STDR. Conventional treatment with anti-vascular endothelial growth factor agents for STDME can potentially lead to foetal loss. Treatment with laser photocoagulation may be preferred, and surgery under general anaesthesia should be avoided. This review provides a management plan for STDR from the perspective of practising ophthalmologists. A review of strategies for maintaining the eyesight of diabetic women with STDR with emphasis on prepregnancy counselling and planning, monitoring and safe treatment during pregnancy, and management of complications is presented.

Abstract
PURPOSE OF REVIEW Diabetes can be associated with profound visual loss due to several mechanisms. As the duration of diabetes and blood glucose levels increase, these changes become more severe. The proliferation of new blood vessels, vitreous hemorrhage, and tractional retinal detachments may ultimately result and can be devastating to visual function. New advances, including anti-vascular endothelial growth factor (VEGF) medications and innovative microsurgical instruments, have provided additional methods for the management of diabetic retinopathy in the clinic and in the operating room, leading to improved outcomes. RECENT FINDINGS Advances in earlier treatment of proliferative diabetic retinopathy, especially with anti-VEGF injections, allow for a reduction in severity, improved vision, and more controlled and successful surgery. Modern surgical techniques and instrumentation have also allowed for improved patient outcomes. Future research into sustained delivery and release of anti-VEGF, reducing the need for frequent in-office injections, may prove to be additionally beneficial. Over the last decade, anti-VEGF has become an increasingly common treatment modality for the management of proliferative diabetic retinopathy, vitreous hemorrhages, and tractional retinal detachments. Further research is needed to determine the ideal method of delivery and timing of the treatment.

Abstract
Diabetic macular edema (DME) is the main cause of visual impairment associated with diabetic retinopathy (DR) and macular laser, during approximately three decades, and was the single treatment option. More recently, intravitreous injections of anti-angiogenics and corticosteroids modified the treatment paradigm associated with significant vision improvements. Nevertheless, not all patients respond satisfactorily to anti-VEGF or corticosteroid injections, so an adequate treatment choice and a prompt switch in therapeutic class is recommended. Several algorithms and guidelines have been proposed for treating center involving DME to improve patients’ vision and quality of life. However, in Portugal, such guidelines are lacking. The present review aimed to provide guidelines for the treatment options and patient monitorization in the management of center-involving DME. We recommend anti-vascular endothelial growth factor (VEGF) as first-line therapy after a clinical evaluation accompanied by a rigorous metabolic control. Depending on the response obtained after 3–6 monthly intravitreal injections we suggest switching outside the class in case of a non-responder, maintaining the anti-VEGF-therapy in responders to anti-angiogenics. The treatment regimen for Dexamethasone intravitreal implant (DEXii) should be pro-re-nata with bi-monthly or quarterly monitoring visits (with a scheduled visit at 6–8 weeks after DEXii for intraocular pressure control). If a patient does not respond to DEXii, switch again to anti-VEGF therapy, combine therapies, or re-evaluate patients diagnose. There is a resilient need to understand the disease, its treatments, regimens available, and convenience for all involved to propose an adequate algorithm for the treatment of diabetic retinopathy (DR) and DME in an individualized regimen. Further understanding of the contributing factors to the development and progression of DR should bring new drug discoveries for more effective and better-tolerated treatments.

Abstract
INTRODUCTION Anti-angiogenesis therapy with intravitreal anti-VEGF agents is now the standard-of-care treatment for myopic choroidal neovascularization (CNV). AREAS COVERED We provide a critical review of the safety of all the anti-VEGF agents currently used for treating myopic CNV including ranibizumab, aflibercept, conbercept, bevacizumab, and ziv-aflibercept. EXPERT OPINION Anti-VEGF therapy for myopic CNV with the currently available anti-VEGF drugs generally have favorable safety outcomes in the short-term. Nonetheless, ocular adverse events following anti-VEGF therapy for myopic CNV may develop and these include worsening or new development of myopic traction maculopathy, increased risk of retinal detachment, and progression of chorioretinal atrophy. Clinicians should be aware of these potential complications and evaluate them before and after anti-VEGF therapy.

Abstract
The aim of this review article is to summarize the available literature on physiologic and pathologic ocular changes during pregnancy and the effect of diseases in pregnancy. A literature search was conducted using PUBMED, MEDLINE, and Cochrane library in English. In addition, the cited references in the published articles were manually reviewed for the relevant results. Pregnancy encompasses a multitude of changes in all body systems, including the visual system of the female. The changes can be physiological, i.e., changes occurring in the lids and adnexa, cornea, conjunctiva, changes in tear film composition and intraocular pressure, retina, choroid, and visual field. Pathological changes in a pregnant woman's eye include changes related to preeclampsia and eclampsia, central serous chorioretinopathy, retinal artery or vein occlusions, and disseminated intravascular coagulation. Preexisting diseases like diabetic retinopathy, Graves' disease, idiopathic intracranial hypertension, various inflammatory conditions can undergo changes in their course during pregnancy. Ophthalmic medications can have an effect on both mother and the baby and hence should be used cautiously. In addition, intrauterine infections play a major role in causing inflammation in the eye of the baby. Hence, vaccination of the mother prior to pregnancy plays an important role in preventing intrauterine infections in the neonate. A regular eye examination in the perinatal period plays a vital role in recognizing ophthalmic pathologies which might require a prompt medical intervention. Pathological ocular diseases should be discriminated from physiologic changes to establish an individualized treatment or preventive plan. This approach to ocular benefits of treatment to the mother should always weigh against the potential harm to the fetus.

Abstract
Pregnancy is associated with increased risk of progression of diabetic retinopathy (DR), the greatest risk of worsening occurs during the second trimester of pregnancy and persists as long as one year after the childbirth. The risk factors include duration of the diabetes, insufficient metabolic control, severity of DR at the time of conception and presence of coexisting vascular disease, such as arterial hypertension, and pregnancy itself. The recommendations for retinopathy screening in pregnancy vary significantly. A dilated fundus exam should be done in the beginning of pregnancy, the next follow-up throughout pregnancy depends on the severity of ocular findings. The cooperation of multi-disciplinary team consisting of ophthalmologist, obstetrition and endocrinologist is essential to provide the best health care. The authors present a case report of a pregnant woman with type 1 diabetes mellitus (DM), who had a progression of DR and diabetic macular edema (DME) in both eyes during pregnancy. She has had DM for 24 years and has been treated with insulin. The patient was examined at the 23rd week of the second pregnancy (first pregnancy was terminated because of missed miscarriage). The diagnosis of advanced proliferative DR and advanced DME in both eyes was made so we performed panretinal laser photocoagulation of the retina of both eyes. Despite that the ocular findings got worse and we found vitreous haemorrhage in the left eye. We performed pars plana vitrectomy (PPV) of the left eye at the 28th week of pregnancy, nevertheless the DME got worse in both eyes, so we recommended to terminate the pregnancy at the 31st week because of the risk of loss of vision. The visual acuity of the left eye improved, but suddenly there was vitreous haemorrhage in the right eye after the delivery. We indicated PPV of the right eye, the outcome of the surgery was satisfying. We still take care about this patient.

Abstract
Background Choroidal neovascularization (CNV) in pregnancy has rarely been described. A differential diagnosis between inflammatory, idiopathic, and myopic CNV may be challenging. Moreover, there is no consensus on management, and therapeutic options may be further limited by patient and physician concerns about potential risk to the fetus. Herein, we report a case of inflammatory CNV during pregnancy and describe a previously unreported management approach with retrobulbar triamcinolone injections. Case presentation A 36-year-old woman presented with vision loss and metamorphopsia in her right eye while 21 weeks pregnant. She was diagnosed with an inflammatory CNV based on the following multimodal imaging findings: a type 2 lesion with the “pitchfork sign” on OCT, along with the absence of tomographic signs of myopic CNV, and the presence on autofluorescence of multiple hyper-autofluorescent spots, interpreted as focal areas of inflammation at the level of the outer retina and inner choroid. The patient refused oral corticosteroids and any intravitreal injection therapies. Therefore, she was treated with two trans-Tenon’s retrobulbar injections of triamcinolone acetonide after explaining the procedure and acquiring consent. The treatment resulted in a regression of inflammatory signs and a reduction of neovascular activity. No adverse events occurred for the mother or the baby, neither during the pregnancy nor after delivery. Conclusion Inflammatory CNV may be rarely associated with pregnancy. The correct diagnosis is crucial to allow the consideration of all possible management options. To the best of our knowledge, this is the first reported case of treatment with retrobulbar triamcinolone injections. This may represent a suitable therapeutic option in the absence of any other therapeutic approaches.

Abstract
PURPOSE Anti-vascular endothelial growth factor (VEGF) medications are widely used for treatment of a number of vitreoretinal disorders. However, the evidence for their effect on fetal and maternal health during pregnancy is very limited. The goal of this article is to accumulate evidence for the indications of anti-VEGF medications during pregnancy and their effects on maternal and fetal health. METHODS Review of literature regarding anti-VEGF administration during pregnancy and using PubMed database without language or date limit. RESULTS The main indications for treatment with intravitreal anti-VEGF medications include choroidal neovascularization (CNV) followed by retinal vascular occlusion (RVO) and complications of diabetes such as neovascular glaucoma, diabetic retinopathy (DR) and diabetic macular edema (DME). Among anti-VEGF medications, only ranibizumab and bevacizumab have been used during pregnancy with latter by far more than the former. CONCLUSION Women of childbearing age should be consulted regarding the potential adverse effects of anti-VEGF medications on fetal health and the risk of early pregnancy loss. They should be strongly encouraged to use appropriate contraceptive methods during treatment. A timely obstetrics consultation may help in this situation. Attempt for pregnancy should be withheld for at least 3 months following last injection of ranibizumab and aflibercept, and for at least 6 months following last injection of bevacizumab.

Abstract
PURPOSE To report the clinical course and treatment outcomes of a patient with central retinal vein occlusion (CRVO) with severe macular edema in early pregnancy. METHODS Interventional case report. RESULTS A 39-year-old woman with gestational diabetes mellitus and a 15-pack year smoking history presented at 7 weeks gestation with decreased vision due to CRVO with marked macular edema. One month later visual acuity had decreased to 20/400 and macular edema had worsened to a central subfield thickness of 1432 µm. She was treated with a single intravitreal dexamethasone implant at 16 weeks gestation. She responded well with visual acuity improving to 20/40+ and complete resolution of macular edema. At 33 weeks gestation the cystoid macular edema recurred but the patient refused treatment. The cystoid macular edema spontaneously resolved 3 weeks postpartum but recurred 3 months later with visual acuity worsening to 20/50. This macular edema resolved completely after a single 1.25 mg bevacizumab injection. She required no further treatment and 23 months later her macula was dry with visual acuity of 20/25. Her baby was healthy. CONCLUSIONS Although pregnancy appears to aggravate CRVO-associated macular edema, the visual loss may be reversible. Intravitreal steroid appears to be effective during pregnancy with no apparent systemic or fetal complications. Young patients with RVO and center-involving macular edema may stabilize with minimal treatment.

Abstract
Drug delivery into the vitreous chamber remains a great challenge in the pharmaceutical industry due to the complex anatomy and physiology of the eye. Intravitreal injection is the mainstream route of drug administration to the posterior segment of the eye. The purpose of this review is to assess the current literature about the widening use of the intravitreal 0.7 mg dexamethasone (Dex) implant, and to provide a comprehensive collection of all the ocular disorders that benefit from Dex administration. Although anti-vascular endothelial growth-factors (VEGFs) have been largely indicated as a first-choice level, the Dex implant represents an important treatment option, especially in selected cases, such as vitrectomized eyes or patients in whom anti-VEGF failed or are contraindicated. In this article, the safety profile as well as the list of the possible complications related to intravitreal Dex injection are also discussed.

Abstract
Objective Treatment of coronavirus disease 2019 is mostly symptomatic, but a wide range of medications are under investigation against severe acute respiratory syndrome coronavirus 2. Although pregnant women are excluded from clinical trials, they will inevitably receive therapies whenever they seem effective in nonpregnant patients and even under compassionate use. Methods We conducted a review of the literature on placental transfer and pregnancy safety data of drugs under current investigation for coronavirus disease 2019. Results Regarding remdesivir, there are no data in pregnant women. Several other candidates already have safety data in pregnant women, because they are repurposed drugs already used for their established indications. Thus, they may be used in pregnancy, although their safety in the context of coronavirus disease 2019 may differ from conventional use. These include HIV protease inhibitors such as lopinavir/ritonavir that have low placental transfer, interferon that does not cross the placental barrier, and hydroxychloroquine or chloroquine that has high placental transfer. There are also pregnancy safety and placental transfer data for colchicine, steroids, oseltamivir, azithromycin, and some monoclonal antibodies. However, some drugs are strictly prohibited in pregnancy because of known teratogenicity (thalidomide) or fetal toxicities (renin-angiotensin system blockers). Other candidates including tocilizumab, other interleukin 6 inhibitors, umifenovir, and favipiravir have insufficient data on pregnancy outcomes. Conclusion In life-threatening cases of coronavirus disease 2019, the potential risks of therapy to the fetus may be more than offset by the benefit of curing the mother. Although preclinical and placental transfer studies are required for a number of potential anti-severe acute respiratory syndrome coronavirus 2 drugs, several medications can already be used in pregnant women.

Abstract
Pregnancy is a normal state of physiological stress that induces significant changes in the human body, some of which can potentially affect the visual system. The pregnant state may exacerbate pre-existing ocular disorders (i.e. diabetic retinopathy or central serous retinopathy). Moreover, other systemic conditions related to pregnancy can induce ophthalmic disorders affecting the retina and the choroid, some of which are of acute nature. Increasing awareness and improving collaboration between ophthalmologists, obstetricians and internists can play a pivotal role in the management of complex conditions during pregnancy. Special attention should be given while prescribing medications or deciding about other diagnostic or therapeutic techniques. The purpose of this review is to summarise the physiologic and pathologic effects of pregnancy in the eyes, highlighting the most acute clinical entities that may be threatening for the vision or even the life of the mother and her baby.

Abstract
The aim of this article is to provide an overview of characteristics and principles of use of dexamethasone implant in patients with diabetic macular edema (DME). The condensed information about patient selection, dosing, and postinjection management is provided to make the clinician’s decisions easier in real-life practice. DME is a common complication of diabetes and the leading cause of visual loss in the working-age population. Inflammation plays an important role in the pathogenesis of DME. The breakdown of the blood–retinal barrier involves the expression of inflammatory cytokines and growth factors, including vascular endothelial growth factor (VEGF). Steroids have proved to be effective in the treatment of DME by blocking the production of VEGF and other inflammatory cytokines, by inhibiting leukostasis, and by enhancing the barrier function of vascular endothelial cell tight junctions. Dexamethasone intravitreal implant has demonstrated efficacy in the treatment of DME resistant to anti-VEGF therapy and in vitrectomized eyes. Data from clinical trials suggest that dexamethasone implant can be considered as first-line treatment in pseudophakic eyes. Dexamethasone implant is also the first-line therapy in patients not suited for anti-VEGF therapy, pregnant women, and patients unable to return for frequent monitoring. It has been shown that the maximum effect of dexamethasone implant on visual gain and retinal thickness occurs approximately 2 months after injection. Various treatment regimens are used in real-life situations, and reported reinjection intervals were usually <6 months. The number of retreatments needed decreased over time. Treatment algorithms should be personalized. Postinjection management and follow-up should consider potential adverse events such as intraocular pressure elevation and cataract.

Abstract
The aim of this case report was to describe a miscarriage which occurred 6 days after an intravitreal Ranibizumab (IVR) injection. A 24-year-old female patient with type 1 diabetes diagnosed with diabetic macular edema in her left eye planned for 3 injections of IVR at one-month intervals. She had been receiving insulin injections 3 times a day and her Hemoglobin A1C (HbA1c) was in the approximate range of 6-7%. An ophthalmologic examination revealed that the patient's Snellen corrected distance visual acuity (CDVA) was 10/10 in her right eye and 3/10 in her left eye. The patient was unaware of her pregnancy at the time of initial injection. Two days after the first injection, she found out that she was 5 weeks pregnant. This was the first pregnancy for the patient and there were no risk factors for miscarriage rather than diabetes. Six days after the injection, she was admitted to the hospital due to severe abdominal pain and vaginal bleeding. Miscarriage was diagnosed and she underwent curettage procedure. We concluded that pregnancy tests should be administered prior to intravitreal injection for female patients of reproductive age, and patient testimony should not be the sole reason to dismiss the possibility of pregnancy.

Abstract
INTRODUCTION Cancer during pregnancy is a rare but challenging condition. More women delay childbearing and consequently the incidence of cancer during pregnancy is constantly increasing. EVIDENCE ACQUISITION An extensive electronic search was performed in PubMed and Scopus. Only studies written after 1985 were considered eligible for this review. Abstracts, conference papers, book chapters, animal studies, commentaries as well as editorials articles were excluded from this review. EVIDENCE SYNTHESIS Cancer treatment during pregnancy is possible, but both maternal and fetal conditions need to be preserved. Randomized clinical trials are not feasible and current evidence are mainly based on case-series, small case reports and expert opinion. Cervical and ovarian cancers are the most common gynecological cancers diagnosed during pregnancy. Surgery and chemotherapy after the first trimester seem to be relatively safe for the newborn. Platinum-based chemotherapy administered during the 2nd-3rd trimester showed comparable adverse effects in newborns to those in the general population. Babies exposed to antenatal chemotherapy might be more likely to develop small for gestational age and NICU admission, than babies not exposed. CONCLUSIONS Management of pregnant women with cancer should be performed in specialized cancer centers and all cases should be discussed with a multidisciplinary approach. In the present review, we discuss the current recommendations for the management of pregnancies complicated by cancer and neonatal outcomes.

Abstract
Diabetes is a common chronic condition in women of reproductive age. Preconception care is crucial to reducing the risk of adverse maternal and fetal outcomes, such as hypertensive disorders, abnormal fetal growth, traumatic delivery and stillbirth, associated with poor glycemic control. Insulin is the preferred medication to optimize glucose control in women with pregestational diabetes. Frequent dose adjustments are needed during pregnancy to achieve glycemic goals, and team-based multidisciplinary care may help. Postpartum care should include lactation support, counseling on contraceptive options, and transition to primary care.

Abstract
Intravitreal injections (IVI) have become the most common intraocular procedure worldwide with increasing numbers every year. The article presents the most up-to-date review on IVI epidemiology and techniques. Unfortunately, important issues related to pre-, peri- and postinjection management lack randomized clinical trials for a final conclusion. Also, a great diversity of approaches exists worldwide. Therefore, expert consensus recommendations on IVI techniques are provided.

Abstract
PurposeRanibizumab is used in the treatment of choroidal neovascularization (CNV). Although systemic exposure to ranibizumab is low after ocular administration, its mechanism of action must be regarded as potentially teratogenic and embryo-fetotoxic. Women are advised to wait 3 months after the last dose of treatment with ranibizumab before conceiving. Little is known about the fetal side-effects of this drug.MethodsThree pregnant women were treated with ranibizumab. One patient had idiopathic CNV.ResultsAfter receiving injections at 10 and 21 weeks after her last menstrual period (LMP), she gave birth to a healthy child. The second patient had myopic choroidal neovascularization (mCNV) and was treated by a single injection at 17 weeks post LMP. She gave birth to a healthy child after an uneventful pregnancy. The third patient had CNV secondary to a punctuate inner choroiditis. The injection was performed at 8 weeks post LMP. This patient presented a cholestasis of pregnancy at 36 weeks post LMP and gave birth at 38 weeks post LMP to a child that did not present any malformations.ConclusionsThis case series describes three women who underwent intravitreal ranibizumab treatment during pregnancy without showing any obstetric, embryofetal or neonatal complications.

Abstract
Pregnancy leads to significant changes in the body, which potentially affect the retina. Pregnancy can induce disease, such as that seen in hypertensive retinopathy and choroidopathy. It can cause exudative retinal detachments in the HELLP syndrome (hemolysis, elevated liver enzymes and low platelets), disseminated intravascular coagulation (DIC), and thrombotic thrombocytopenic purpura (TTP), and provoke arterial and venous retinal occlusive disease. Pregnancy may also exacerbate pre-existing retinal disease, such as idiopathic central serous chorioretinopathy (ICSC) and diabetic retinopathy. Special consideration needs to be exercised when treating pregnant patients in choosing medications, as well as in selecting diagnostic modalities and surgical methods.

Abstract
Pathologic myopia is a leading cause of visual impairment. Development of myopic choroidal neovascularization (CNV) is one of the most common complications that leads to central vision loss in patients with pathologic myopia. If left untreated, it can cause scarring with expanding macular atrophy leading to irreversible visual loss in a period as short as 5 years. Advancements in multimodal imaging technology have furthered our understanding of the condition; however, further studies are necessary to extend its utility in the diagnosis of myopic CNV. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) therapy has become the standard-of-care and the recommended first-line treatment option for myopic CNV. Long-term studies have demonstrated that early treatment of confirmed myopic CNV cases with an intravitreal anti-VEGF agent is useful to avoid late-stage complications. This strategy has also been shown to achieve visual outcome improvements for up to 4 years and visual stabilization up to 6 years. This review article provides an overview of the current knowledge on myopic CNV and discusses recent updates in the diagnosis and management of the condition. Furthermore, treatment recommendations are provided based on the authors' expert opinions.

Abstract
There are a number of barriers that result in cancer patients not being referred for oncofertility care, which include knowledge about reproductive risks of antineoplastic agents. Without this information, clinicians do not always make recommendations for oncofertility care. The objective of this study was to describe the level of reproductive information and recommendations that clinicians have available in clinical trial protocols regarding oncofertility management and follow-up, and the information that patients may receive in clinical trials patient information sheets or consent forms. A literature review of the 71 antineoplastic drugs included in the 68 clinical trial protocols showed that 68% of the antineoplastic drugs had gonadotoxic animal data, 32% had gonadotoxic human data, 83% had teratogenic animal data, and 32% had teratogenic human data. When the clinical trial protocols were reviewed, only 22% of the protocols reported the teratogenic risks and 32% of the protocols reported the gonadotoxic risk. Only 56% of phase 3 protocols had gonadotoxic information and 13% of phase 3 protocols had teratogenic information. Nine percent of the protocols provided fertility preservation recommendations and 4% provided reproductive information in the follow-up and survivorship period. Twenty-six percent had a section in the clinical trials protocol, which identified oncofertility information easily. When gonadotoxic and teratogenic effects of treatment were known, they were not consistently included in the clinical trial protocols and the lack of data for new drugs was not reported. Very few protocols gave recommendations for oncofertility management and follow-up following the completion of cancer treatment. The research team proposes a number of recommendations that should be required for clinicians and pharmaceutical companies developing new trials.

Shared mechanism of teratogenicity of anti-angiogenic drugs identified in the chicken embryo model. Sci Rep 2016; 6:30038.

Abstract
Angiogenesis, the formation of new blood vessels, is essential for tumor growth, stabilization and progression. Angiogenesis inhibitors are now widely used in the clinic; however, there are relatively few published studies on the mechanism of their presumed teratogenic effects. To address this issue, we screened a variety of angiogenesis inhibitors in developing zebrafish and chicken embryo models to assess for developmental defects and potential teratogenic effects. We confirmed previous reports that sunitinib, sorafenib and TNP-470 are teratogenic and demonstrate that axitinib, pazopanib, vandetanib, and everolimus are also teratogens in these models. A dose response study identified the drugs inhibit HUVEC cell proliferation in vitro, and also target the developing blood vessels of embryos in vivo. This provides further evidence for the potential risk of fetal toxicity when using these drugs in a clinical setting, and emphasizes the importance of the development and maintenance of the vasculature in the embryo. We conclude that angiogenesis inhibitors, regardless of the molecular target, are teratogenic when exposed to chicken embryos.
