Risk of retinopathy in women with pregnancy-induced hypertension: a nationwide population-based cohort study of 9-year follow-up after delivery. Am J Obstet Gynecol MFM 2023; 5:100985. [PMID: 37119970 DOI: 10.1016/j.ajogmf.2023.100985] [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: 02/02/2023] [Revised: 04/19/2023] [Accepted: 04/21/2023] [Indexed: 05/01/2023]
Abstract
BACKGROUND The retina is potentially associated with several physiological, hormonal, and metabolic changes during pregnancy. The few available epidemiologic studies of ocular changes in pregnancy have mainly concerned retinopathies. Pregnancy-induced hypertension, which leads to ocular manifestations including blurred vision, photopsia, scotoma, and diplopia, might induce reactive changes in the retinal vessels. Although several studies have suggested the existence of pregnancy-induced hypertension-related retinal ocular disease, there are few large cohort studies on this topic. OBJECTIVE This study aimed to investigate the risk of major retinal diseases including central serous chorioretinopathy, diabetic retinopathy, retinal vein occlusion, retinal artery occlusion, and hypertensive retinopathy in the long-term postpartum stage according to the presence of previous pregnancy-induced hypertension in a large cohort based on the Korean National Health Insurance Database. STUDY DESIGN On the basis of Korean health data, 909,520 patients who delivered from 2012 to 2013 were analyzed. Among them, patients who had previous ocular diseases or hypertension and multiple births were excluded. Finally, 858,057 mothers were assessed for central serous chorioretinopathy (ICD-10: H35.70), diabetic retinopathy (ICD-10: H36.0, E10.31, E10.32, E11.31, E11.32, E12.31, E13.31, E13.32, E14.31, E14.32), retinal vein occlusion (ICD-10: H34.8), retinal artery occlusion (ICD-10: H34.2), and hypertensive retinopathy (ICD-10: H35.02) for 9 years after delivery. Enrolled patients were divided into 2 groups: 10,808 patients with and 847,249 without pregnancy-induced hypertension. The primary outcomes were the incidence of central serous chorioretinopathy, diabetic retinopathy, retinal vein occlusion, retinal artery occlusion, and hypertensive retinopathy 9 years after delivery. Clinical variables were age, parity, cesarean delivery, gestational diabetes mellitus, and postpartum hemorrhage. In addition, pregestational diabetes mellitus, kidney diseases, cerebrovascular diseases, and cardiovascular diseases were adjusted. RESULTS Postpartum retinal disease during the 9 years after delivery and total retinal diseases showed higher rates in patients with pregnancy-induced hypertension. In detail, the rates of central serous chorioretinopathy (0.3% vs 0.1%), diabetic retinopathy (1.79% vs 0.5%), retinal vein occlusion (0.19% vs 0.1%), and hypertensive retinopathy (0.62% vs 0.05%) were higher than those found in patients without pregnancy-induced hypertension. After adjusting for confounding factors, pregnancy-induced hypertension was associated with development of postpartum retinopathy, with a >2-fold increase (hazard ratio, 2.845; 95% confidence interval, 2.54-3.188). Furthermore, pregnancy-induced hypertension affected the development of central serous chorioretinopathy (hazard ratio, 3.681; 95% confidence interval, 2.667-5.082), diabetic retinopathy (hazard ratio, 2.326; 95% confidence interval, 2.013-2.688), retinal vein occlusion (hazard ratio, 2.241; 95% confidence interval, 1.491-3.368), and hypertensive retinopathy (hazard ratio, 11.392; 95% confidence interval, 8.771-14.796) after delivery. CONCLUSION A history of pregnancy-induced hypertension increases the risk of central serous chorioretinopathy, diabetic retinopathy, retinal vein occlusion, and hypertensive retinopathy according to 9-year long-term ophthalmologic follow-up.

Abstract
OBJECTIVES Diabetic retinopathy is a common microvascular complication of diabetes. Despite that, there are few studies in the literature to address pregnancy, delivery, or neonatal outcomes among women with diabetic retinopathy. METHODS We conducted a retrospective study using the Health Care Cost and Utilization Project-Nationwide Inpatient Sample Database over 11 years from 2004 to 2014. A delivery cohort was created using ICD-9 codes. ICD-9 code 250 or 249 was used to extract the cases of maternal diabetic retinopathy. A multivariant logistic regression model was used to adjust for statistically significant variables (p-value ≤ .05). RESULTS There were a total of 9,096,788 deliveries during the study period. Of those, 86 615 pregnant women were found to have Diabetes Mellites (DM). Diabetic retinopathy was present in 1233 of the patients with DM. Diabetic retinopathy increased the likelihood of developing pregnancy-induced HTN (p < .0001), Preeclampsia (p < .0001), and Preeclampsia and eclampsia superimposed on preexisting HTN (p < .0001). In addition, in women with DM, the presence of diabetic retinopathy increased the risk of Preterm delivery (p = .002), cesarean section (p < .0001), requiring transfusion (p < .0001), and undergoing hysterectomy (p = .001), and were less likely to have a spontaneous vaginal delivery (p < .0001). However, the presence of diabetic retinopathy in women with DM did not increase the risk of the fetus being small at delivery, having intrauterine fetal demise, or congenital anomalies. CONCLUSION Women with diabetic retinopathy should be counseled about their increased risk of pregnancy-induced HTN, preeclampsia, premature delivery, cesarean section, transfusion, and hysterectomy.

Abstract
Despite being a physiological condition, human pregnancy is known to cause numerous complications that can endanger the life of the mother and the fetus alike. While the majority of complications are mostly limited within the peripartum period, more and more information is available about persistently higher short- and long-term cardiovascular risk after a pregnancy complicated by a hypertensive disorder. There is evidence that women after gestational hypertension or preeclampsia are more likely to develop arterial hypertension, coronary atherosclerosis, myocardial infarction, stroke, peripheral artery disease, and even diabetes mellitus and venous thromboembolism years after the target pregnancy. This has urged some authors to view hypertensive disorders of pregnancy as a "stress test" for the maternal organism that unmasks latent endothelial dysfunction. An explanation is sought in the presence of common risk factors and underlying pathological pathways with cardiovascular diseases, although a certain etiological mechanism for the development of hypertensive disorders in pregnancy has not been established yet. More attention is needed towards the follow-up of women after a hypertensive pregnancy as it could be an opportunity for early prevention of cardiovascular diseases.

Abstract
Background: Pre-eclampsia is a serious consideration for women with type 1 diabetes mellitus (T1DM) planning pregnancy. Risk stratification strategies, such as biomarkers measured in the first trimester of pregnancy, could help identify high-risk women. The literature on T1DM-specific pre-eclampsia biomarkers is expanding. We aimed to provide a narrative review of recently published evidence to identify the most promising biomarker candidates that could be targeted for clinical implementation in existing PE models. Methods: A search using MeSH terms was carried out of Medline, EMBASE, Maternity and Infant Care, Web of Science, and Scopus for relevant papers published since 2015 inclusive and in English. The time limit was applied from the publication of the preceding systematic review in this field. Included studies had pre-eclampsia as a primary outcome, measured one or more serum, plasma or urine biomarkers at any time during pregnancy, and had a distinct group of women with T1DM who developed pre-eclampsia. Studies with pre-eclampsia as a composite outcome were not considered. No restrictions on study types were applied. A narrative synthesis approach was adopted for analysis. Results: A total of 510 records were screened yielding 18 eligible studies relating to 32 different biomarkers. Higher first-trimester levels of HbA1c and urinary albumin were associated with an increased risk of pre-eclampsia development in women with T1DM. Urinary neutrophil gelatinase-associated lipocalin and adipokines were novel biomarkers showing moderate predictive ability before 15 gestational weeks. Two T1DM-specific pre-eclampsia prediction models were proposed, measuring adipokines or urinary neutrophil gelatinase-associated lipocalin together with easily attainable maternal clinical characteristics. Contradicting previous literature, pre-eclampsia risk in women with T1DM was correlated with vitamin D levels and atherogenic lipid profile in the context of haptoglobin phenotype 2-2. Pregnancy-associated plasma protein-A and soluble endoglin did not predict pre-eclampsia in women with T1DM, and soluble Fms-like tyrosine kinase 1 only predicted pre-eclampsia from the third trimester. Conclusion: Maternally derived biomarkers reflecting glycemic control, insulin resistance and renal dysfunction performed better as PE predictors among women with T1DM than those derived from the placenta. These biomarkers could be trialed in current PE prediction algorithms to tailor them for women with T1DM.

Abstract
BACKGROUND The rise in the global prevalence of diabetes, particularly among younger people, has led to an increase in the number of pregnant women with preexisting diabetes, many of whom have diabetes-related microvascular complications. We aimed to estimate the magnitude of the risks of adverse pregnancy outcomes or disease progression in this population. METHODS AND FINDINGS We undertook a systematic review and meta-analysis on maternal and perinatal complications in women with type 1 or 2 diabetic microvascular disease and the risk factors for worsening of microvascular disease in pregnancy using a prospective protocol (PROSPERO CRD42017076647). We searched major databases (January 1990 to July 2021) for relevant cohort studies. Study quality was assessed using the Newcastle-Ottawa Scale. We summarized the findings as odds ratios (ORs) with 95% confidence intervals (CIs) using random effects meta-analysis. We included 56 cohort studies involving 12,819 pregnant women with diabetes; including 40 from Europe and 9 from North America. Pregnant women with diabetic nephropathy were at greater risk of preeclampsia (OR 10.76, CI 6.43 to 17.99, p < 0.001), early (<34 weeks) (OR 6.90, 95% CI 3.38 to 14.06, p < 0.001) and any preterm birth (OR 4.48, CI 3.40 to 5.92, p < 0.001), and cesarean section (OR 3.04, CI 1.24 to 7.47, p = 0.015); their babies were at higher risk of perinatal death (OR 2.26, CI 1.07 to 4.75, p = 0.032), congenital abnormality (OR 2.71, CI 1.58 to 4.66, p < 0.001), small for gestational age (OR 16.89, CI 7.07 to 40.37, p < 0.001), and admission to neonatal unit (OR 2.59, CI 1.72 to 3.90, p < 0.001) compared to those without nephropathy. Diabetic retinopathy was associated with any preterm birth (OR 1.67, CI 1.27 to 2.20, p < 0.001) and preeclampsia (OR 2.20, CI 1.57 to 3.10, p < 0.001) but not other complications. The risks of onset or worsening of retinopathy were increased in women who were nulliparous (OR 1.75, 95% CI 1.28 to 2.40, p < 0.001), smokers (OR 2.31, 95% CI 1.25 to 4.27, p = 0.008), with existing proliferative disease (OR 2.12, 95% CI 1.11 to 4.04, p = 0.022), and longer duration of diabetes (weighted mean difference: 4.51 years, 95% CI 2.26 to 6.76, p < 0.001) compared to those without the risk factors. The main limitations of this analysis are the heterogeneity of definition of retinopathy and nephropathy and the inclusion of women both with type 1 and type 2 diabetes. CONCLUSIONS In pregnant women with diabetes, presence of nephropathy and/or retinopathy appear to further increase the risks of maternal complications.

Abstract
PURPOSE OF REVIEW The aim of this study was to summarize common eye changes that may occur during pregnancy, and how pregnancy may affect preexisting eye conditions such as glaucoma and diabetic retinopathy. Challenges and complexities surrounding the treatment of these eye conditions during pregnancy are also highlighted. RECENT FINDINGS Refractive changes are common and may persist in the postpartum in patients with keratoconus. Although new medical and surgical glaucoma treatments are available, their safety in pregnancy is unknown. Limited use of topical and systemic glaucoma therapies is recommended, with a preference for selective laser trabeculoplasty as first line treatment in appropriate cases. The impact of pregnancy on diabetic retinopathy remains unclear. Although anti-vascular endothelial growth factor agents are first-line treatment for sight-threatening diabetic retinopathy, their effect on the developing foetus remains unknown and are therefore best avoided in the first and second trimesters. Noninfectious uveitis tends to become less active during pregnancy, allowing the potential tapering of systemic therapy and the use of local topical or injected corticosteroid treatment for active disease as required. SUMMARY Significant changes can occur to the eye during pregnancy, wherein the optimal treatment for many ocular conditions remains uncertain, highlighting the need for further research to develop clear recommendations that best balance the need to preserve the mother's sight, and the health of the developing foetus. The need for preconception planning, and collaborative multidisciplinary care between the obstetrician, physician, ophthalmologist and paediatrician is paramount.

Abstract
The management of diabetic retinopathy (DR) has evolved considerably over the past decade, with the availability of new technologies (diagnostic and therapeutic). As such, the existing Royal College of Ophthalmologists DR Guidelines (2013) are outdated, and to the best of our knowledge are not under revision at present. Furthermore, there are no other UK guidelines covering all available treatments, and there seems to be significant variation around the UK in the management of diabetic macular oedema (DMO). This manuscript provides a summary of reviews the pathogenesis of DR and DMO, including role of vascular endothelial growth factor (VEGF) and non-VEGF cytokines, clinical grading/classification of DMO vis a vis current terminology (of centre-involving [CI-DMO], or non-centre involving [nCI-DMO], systemic risks and their management). The excellent UK DR Screening (DRS) service has continued to evolve and remains world-leading. However, challenges remain, as there are significant variations in equipment used, and reproducible standards of DMO screening nationally. The interphase between DRS and the hospital eye service can only be strengthened with further improvements. The role of modern technology including optical coherence tomography (OCT) and wide-field imaging, and working practices including virtual clinics and their potential in increasing clinic capacity and improving patient experiences and outcomes are discussed. Similarly, potential roles of home monitoring in diabetic eyes in the future are explored. The role of pharmacological (intravitreal injections [IVT] of anti-VEGFs and steroids) and laser therapies are summarised. Generally, IVT anti-VEGF are offered as first line pharmacologic therapy. As requirements of diabetic patients in particular patient groups may vary, including pregnant women, children, and persons with learning difficulties, it is important that DR management is personalised in such particular patient groups. First choice therapy needs to be individualised in these cases and may be intravitreal steroids rather than the standard choice of anti-VEGF agents. Some of these, but not all, are discussed in this document.

Abstract
INTRODUCTION Pregnancy is a risk factor for progression of diabetic retinopathy (DR). Despite the common opinion about the regression of DR after childbirth, it is possible for the disease to progress aggressively, which can cause loss of visual functions when treated untimely. PURPOSE To present clinical cases with different course of development of DR in pregnant women with type 1 diabetes mellitus (DM1). MATERIAL AND METHODS Five pregnant women with DM1 lasting more than 8 years were examined. Glycemic level of all patients was higher than normal (glycated hemoglobin (HbA1c) of more than 6.1%). Ophthalmologic examination was carried out including fundus photography, optical coherence tomography (OCT) of the macular area, Angio-OCT. RESULTS The most significant factors in the progression of DR in pregnant women are DR1 compensation, severity and stabilization of DR during the preconception period, presence of a concomitant pathology. Timely detection of signs of progression of DR and therapeutic measures taken during pregnancy, in particular laser coagulation, were shown to stabilize the course of the disease and prevent loss of vision in pregnant women with DM1. CONCLUSION Clinical course of DR in pregnancy can vary between absence of manifestation, stabilization, and progression. Progression of DR during pregnancy is determined by a number of factors including compensation of DM during the preconception period and throughout pregnancy, severity and stabilization of retinopathy during the preconception period, and presence of a concomitant pathology. Timely detection of the signs of DR progression and its treatment, in particular laser coagulation of the retina, can help stabilize the course of the disease during pregnancy. The course of DR may be aggressive in some pregnant women involving progression in the postpartum period, which warrants active monitoring of patients with retinopathy after childbirth.

Abstract
Purpose We report 2 cases of young diabetic mothers with pre-eclampsia and no previously documented visual deficits prior to pregnancy who were found to have profound retinal circulation loss during the postpartum period. Observations Fluorescein angiogram in both cases documented profound ischemia of retinal and macular circulation with resulting severe vision loss, leading to legal blindness. Conclusions and Importance While Pre-eclampsia and Eclampsia are well known clinical entities with potentially grave effects on both the mother and child, there is little information about the possible combined effects of diabetes and Pre-eclampsia/Eclampsia on the retinal circulation. We aim to raise awareness about this devastating association with a need for aggressive monitoring and prompt treatment of similar patients to potentially avoid poor visual outcomes.

Abstract
BACKGROUND The potential influence of pregnancy and parity on the risk of chronic diabetic complications is a matter of great concern and constant discussion. This aspect seems relevant and should be the subject of thorough discussion with the woman planning childbirth. INTRODUCTION Current data concerning the impact of pregnancy and parity covers primarily retinopathy and nephropathy, while the aspects of neuropathy and macrovascular complications are unsatisfactorily documented. Majority of studies focus on single complication only, while the number of papers assessing this problem in a complex setting is limited. The available body of evidence concerns mainly the short-term impact of pregnancy on diabetic chronic complications while the data concerning the longer perspective are scarce. Moreover, the results found in the available literature are conflicting. The aim of the study was to summarize all available data concerning the longer impact of parity on the chronic complications in the women with type 1 diabetes. METHODS PubMed database has been searched between October 2013 and September 2018 and all relevant papers were selected. This review summarizes data on the impact of pregnancy and parity on chronic complications in type 1 diabetic women. RESULTS Current data assessing this matter in a complex way are limited, and the available results are controversial. It seems however that pregnancy itself may rather influence pre-existing diabetic complication than affect risk of its development. Additionally, evidence suggests that any deleterious changes appearing during pregnancy are transient and tend to remit after delivery. CONCLUSION It seems that neither pregnancy nor parity affects the risk of diabetic chronic complications in the longer perspective.

Abstract
Purpose The objective of this study is to evaluate pattern of diabetic retinopathy (DR) during pregnancy in females with pregestational diabetes mellitus (DM). Methods This is an ambispective observational cohort study conducted at an Indian tertiary care centre. A total of 50 pregnant females with pregestational DM were included while those with gestational DM were excluded from the study. Ocular examination (inclusive of fundus photography) was conducted and systemic parameters (inclusive of Glycated hemoglobin) were assessed during each of the 3 trimesters and 3 months postpartum. The prevalence and progression of DR during pregnancy in the study cohort were the main outcome measures. Results Three of the 50 patients had type 1 DM while 47 had type II DM. All the patients with type I DM were insulin dependent while 19 patients with type II DM were insulin dependent. Overall prevalence of DR was 8% (4/50); 2 cases had nonproliferative DR (NPDR), and 2 had proliferative DR (PDR). During the study period, worsening was seen in both the patients with PDR and one required vitrectomy. Mean visual acuity in patients with PDR decreased from 0.77 logMAR units at presentation to 1.23 logMAR at final follow-up. There was no change in the mean visual acuity of patients with NPDR. None of the patients with NPDR converted to PDR. There was no new onset DR in the patients without DR at presentation. Assessment of risk factors for DR revealed significantly higher duration of DM (14 ± 6.32 years vs. 3.43 ± 1.43 years, P = 0.0008). The median age was also higher in the DR patients (31 years vs. 29 years, P = 0.32). Conclusion No new onset cases were seen during the course of pregnancy and no conversion from NPDR to PDR was seen; however, a worsening of the two PDR cases was observed. No cases of DR were seen in noninsulin-dependent DM. None of the four participants with DR showed a spontaneous resolution of DR postpartum. Patients with PDR and long-standing DM require careful observation during pregnancy. A registry of diabetic mothers should be set up for development of guidelines for managing such cases.

Glycated haemoglobin A1c as a predictor of preeclampsia in type 1 diabetic pregnant women: A systematic review and meta-analysis. Pregnancy Hypertens 2018; 14:49-54. [PMID: 30527118 DOI: 10.1016/j.preghy.2018.04.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/09/2017] [Revised: 03/20/2018] [Accepted: 04/06/2018] [Indexed: 02/01/2023]
Abstract
OBJECTIVE To examine the relationship between the increase of glycated haemoglobin A1c (HbA1c) levels and the risk of preeclampsia in pregnant with type 1 diabetes mellitus; and to determine from which trimester the increase of HbA1c levels better predicts the risk of suffering preeclampsia in type 1 diabetic pregnant women. METHODS We systematically searched MEDLINE, EMBASE, the Cochrane Central Register of Controlled Trials, the Cochrane Database of Systematic Reviews and Web of Science databases, from inception to May 2017, for observational studies addressing the association of HbA1c levels with preeclampsia. Fixed effects models were used to compute pooled estimates of odds ratio (OR) and respective 95% confidence intervals (95% CI) for preeclampsia in type 1 diabetic pregnant women. Additionally, subgroup analyses were performed based on pregnancy trimester. RESULTS Five published studies were included in the systematic review and meta-analysis. There was an increase in the risk of preeclampsia with a 1% increase of HbA1c during pregnancy (OR = 1.38; 95% CI 1.26-1.52, I2=0.0%). When analyses were performed based on pregnancy trimester to estimate the risk of preeclampsia with a 1% increase of HbA1c, pooled OR estimates were 1.37 (95% CI 1.24-1.51, I2=0.0%) for the first trimester and 1.67 (95% CI 1.44-1.93, I2=0.0%) for the second/third trimester. CONCLUSION HbA1c is a reliable predictor of preeclampsia in type 1 diabetic pregnant women. Our findings highlight the importance of including HbA1c measurements in the first antenatal visit to control the risk of preeclampsia in pregnant women.

Abstract
Pregnancy is needed for the perpetuation of the human species, and it leads to physiological adaptations of the various maternal organs and systems. The eye, although a closed space, also undergoes some modifications, most of which are relatively innocuous, but they may occasionally become pathological. For women, pregnancy is a susceptibility period; however, for many obstetricians, their knowledge of the ocular changes that occur during pregnancy tends to be limited. For this reason, this is a important area of study as is necessary the development of guidelines to approach those changes. Of equal importance are the knowledge of the possible therapies for ophthalmological problems in this period and the evaluation of the mode of delivery in particular conditions. For this article, an extensive review of the literature was performed, and a summary of the findings is presented.

Abstract
The prevalence of diabetes in pregnancy is increasing. Pre-existing diabetes is present in 1 in 167 pregnancies in Australia, divided equally between type 1 and type 2 diabetes. Diabetic retinopathy is a leading cause of blindness in women during their childbearing years, and pregnancy increases the short-term risk of diabetic retinopathy progression. We examine the risk factors for progression of diabetic retinopathy during pregnancy including duration of diabetes, baseline level of retinopathy, level of glycaemic control and hypertension. We also examine current screening and management guidelines and their levels of evidence, current treatment options for diabetic retinopathy and avenues for further research.

Abstract
Progression of retinopathy and nephropathy in women with diabetes occurs, at least temporarily, during pregnancy and postpartum. However, normotensive pregnancy seems to have no detrimental effects regarding the long-term progression of any microvascular complication. Increased risk from pregnancy induced hypertension without proteinuria and with proteinuria (pre-eclampsia) relates mainly to the association with kidney disease in diabetes, and poor glycemic control. A history of pre-eclampsia or pregnancy induced hypertension is an important prognostic factor for micro- and macro-vascular complications later in life. Data regarding the long-term effects of hypertensive pregnancies on late complications of diabetes suggest that women with diabetes should be monitored regularly and nephroprotective treatment initiated early.

Abstract
Long-standing hyperglycemia frequently leads to vasculopathy. Microvascular disease is characterized by retinopathy and nephropathy, while macrovascular involvement can affect coronary arteries. Diabetic autonomic neuropathy, when present, is generally associated with retinal and/or renal involvement. Early identification of these diabetic complications allows appropriate counseling and early treatment. Among women with diabetic vasculopathy, nephropathy, chronic hypertension, preeclampsia, preterm delivery, and fetal growth restriction are frequently observed. Furthermore, women with impaired renal function in early pregnancy have increased risk of long-term deterioration of glomerular filtration rate. Proliferative retinopathy can progress during pregnancy and 1 year after delivery, but long-term effects are not likely to occur. When coronary artery disease or gastroparesis diabeticorum are present, excessive maternal and fetal morbidity is observed. When modern management is synchronized with early medical care, favorable maternal and perinatal outcomes can be expected.

Abstract
Preeclampsia is diagnosed in women presenting with new onset hypertension accompanied by proteinuria or other signs of severe organ dysfunction in the second half of pregnancy. Preeclampsia risk is increased 2- to 4-fold among women with type 1 or type 2 diabetes. The limited number of pregnant women with preexisting diabetes and the difficulties associated with diagnosing preeclampsia in women with proteinuria prior to pregnancy are significant barriers to research in this high-risk population. Gestational diabetes mellitus (GDM) also increases preeclampsia risk, although it is unclear whether these two conditions share a common pathophysiological pathway. Nondiabetic women who have had preeclampsia are more likely to develop type 2 diabetes later in life. Among women with type 1 diabetes, a history of preeclampsia is associated with an increased risk of retinopathy and nephropathy. More research examining the pathophysiology, treatment, and the long-term health implications of preeclampsia among women with preexisting and gestational diabetes is needed.

Abstract
The aim of this observational study was to evaluate screening and progression of diabetic retinopathy during pregnancy in women with pregestational diabetes attending five antenatal centres along the Irish Atlantic seaboard. An adequate frequency of screening was defined as at least two retinal evaluations in separate trimesters. Progression was defined as at least one stage of deterioration of diabetic retinopathy and/or development of diabetic macular edema on at least one eye. Women with pregestational diabetes who delivered after 22 gestational weeks (n = 307) were included. In total, 185 (60.3%) had an adequate number of retinal examinations. Attendance at prepregnancy care was associated with receiving adequate screening (odds ratio 6.23; CI 3.39-11.46 (P < 0.001)). Among those who received adequate evaluations (n = 185), 48 (25.9%) had retinopathy progression. Increasing booking systolic blood pressure (OR 1.03, CI 1.01-1.06, P = 0.02) and greater drop in HbA1c between first and third trimesters of pregnancy (OR 2.05, CI 1.09-3.87, P = 0.03) significantly increased the odds of progression. A significant proportion of women continue to demonstrate retinopathy progression during pregnancy. This study highlights the role of prepregnancy care and the importance of close monitoring during pregnancy and identifies those patients at the highest risk for retinopathy progression.

Abstract
The purpose of this paper is to review male-female differences in the incidence and prevalence of diabetes and diabetic retinopathy. These differences will be established primarily through results from our present research and a review of related literature. Previously, we have demonstrated that neuroretinal dysfunction can be used to predict the location of future retinopathy up to three years before it is manifest. Our current research suggests that, for type 2 diabetes, the normal differences in neuroretinal function between nondiabetic males and females under 50 years of age are altered in patients with type 2 diabetes. Furthermore, local neuroretinal function in type 2 diabetes is more abnormal in adult males compared with adult females. The literature also suggests that there are male-female differences in the occurrence of diabetes. In adolescence, the incidence of type 1 diabetes is greater in males, whereas in type 2 diabetes, the incidence is greater in females. This excess of females in type 2 diabetes shifts to a more equal incidence between the two sexes in adults. In addition, advanced retinopathy in type 1 diabetes appears to be more common in males, and the presence and severity of diabetic retinopathy at the time of diagnosis in type 2 diabetes appears to be more associated with male sex. Although the reasons for male-female differences identified in this review are unknown, sex appears to be a significant factor in certain aspects of diabetes incidence and diabetic retinopathy.

Abstract
Diabetic women carry a 2-4 times increased risk of a hypertensive pregnancy compared to non-diabetic people. This risk is related to presence of diabetic nephropathy, but also poor glycaemic control. Efforts to improve glycaemic control have decreased perinatal morbidity and mortality related to diabetic nephropathy. Despite good glycaemic control, overt nephropathy is associated with a variety of pregnancy complications, such as fetal growth restriction and pre-eclampsia. General population studies show that women with a history of pre-eclampsia are more prone to develop cardiovascular disease later in life than women with a history of normotensive pregnancy. Furthermore, recent data regarding the long-term effects of hypertensive pregnancies on late diabetic complications indicate that these women should be followed and treatment should be started early. In this review we summarize data on risk factors and long-term effects of hypertensive pregnancies on late diabetic complications that may be of clinical relevance in the prevention of these complications.

Abstract
Objective: To assess whether glycemic control, soluble fms-like tyrosine kinase 1 (sFlt1) and placental growth factor (PlGF) were associated with the development of preeclampsia (PE) or gestational hypertension (GHTN) in women with preexisting diabetes. Methods: Maternal circulating angiogenic factors (sFlt1 and PlGF) measured on automated platform were studied at four time points during pregnancy in women with diabetes (N = 159) and reported as multiples of the median (MOM) of sFlt1/PlGF ratio (median, 25th–75th percentile) noted in non-diabetic non-hypertensive control pregnant population (N = 139). Diagnosis of PE or GHTN was determined by review of de-identified clinical data. Results: PE developed in 12% (N = 19) and GHTN developed in 23% (N = 37) of the women with diabetes. Among diabetic women without PE or GHTN, median sFlt1/PlGF levels at 35–40 weeks was threefold higher than in non-diabetic controls [MOM 3.21(1.19–7.24), p = 0.0001]. Diabetic women who subsequently developed PE had even greater alterations in sFlt1/PlGF ratio during the third trimester [MOM for PE at 27–34 weeks 15.18 (2.37–26.86), at 35–40 weeks 8.61(1.20–18.27), p ≤ 0.01 for both windows compared to non-diabetic controls]. Women with diabetes who subsequently developed GHTN also had significant alterations in angiogenic factors during third trimester; however, these findings were less striking. Among women with diabetes, glycosylated hemoglobin (HbA1c) during the first trimester was higher in subjects who subsequently developed PE (7.7 vs 6.7%, p = 0.0001 for diabetic PE vs diabetic non-PE). Conclusions: Women with diabetes had a markedly altered anti-angiogenic state late in pregnancy that was further exacerbated in subjects who developed PE. Altered angiogenic factors may be one mechanism for the increased risk of PE in this population. Increased HbA1c in the first trimester of pregnancies in women with diabetes was strongly associated with subsequent PE.

Abstract
OBJECTIVE Our objective was to formulate a clinical practice guideline for the management of the pregnant woman with diabetes. PARTICIPANTS The Task Force was composed of a chair, selected by the Clinical Guidelines Subcommittee of The Endocrine Society, 5 additional experts, a methodologist, and a medical writer. EVIDENCE This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. CONSENSUS PROCESS One group meeting, several conference calls, and innumerable e-mail communications enabled consensus for all recommendations save one with a majority decision being employed for this single exception. CONCLUSIONS Using an evidence-based approach, this Diabetes and Pregnancy Clinical Practice Guideline addresses important clinical issues in the contemporary management of women with type 1 or type 2 diabetes preconceptionally, during pregnancy, and in the postpartum setting and in the diagnosis and management of women with gestational diabetes during and after pregnancy.

Abstract
To investigate whether pre-eclampsia (PE) or pregnancy-induced hypertension (PIH) predicts the development of severe diabetic retinopathy (SDR) in type 1 diabetes. Altogether, 203 women with type 1 diabetes who were followed during pregnancy were re-examined within the Finnish Diabetic Nephropathy Study. After excluding patients with pre-pregnancy hypertension and those who had had laser treatment or whose retinopathy was graded as proliferative at the index pregnancy, 158 were prospectively studied. As a surrogate marker for SDR, retinal laser photocoagulation was used. The time from pregnancy to SDR (N = 21) or follow-up was 16 years (interquartile range, 11-19). HbA1c was repeatedly measured both during pregnancy and follow-up. Women with prior PE (26 % vs. 6 %, P = 0.003) or PIH (24 % vs. 6 %, P = 0.008) had more often incident SDR during follow-up compared to those with normotensive pregnancy. The hazard ratios (HR) remained associated with the progression to SDR after adjustment for duration of diabetes and diabetic nephropathy in a Cox regression analysis [PE: 3.5 (95 % CI 1.1-10.9); P = 0.03 and for PIH: 3.2 (1.1-9.8); P = 0.04]. The association between PIH and incident SDR did not change after inclusion of mean HbA1c, measured during pregnancy (all 3 trimesters) and serial HbA1c measurements during follow-up, 3.5 (1.1-11.8; P = 0.03). However, in a similar model, the HR for PE was no more significant 2.0 (0.6-6.8; P = NS). The results suggest that women with type 1 diabetes and a hypertensive pregnancy have an increased risk of severe diabetic retinopathy later in life.

Abstract
Pregnancy-associated retinal diseases are conditions that may occur uniquely in pregnancy or, more commonly, general conditions that may worsen or alter during pregnancy as a result of hematologic, hormonal, metabolic, cardiovascular, and immunologic changes. Diabetic retinopathy (DR) is by far the most common retinal condition that is altered by pregnancy. However, there are currently no widely accepted, precise clinical guidelines regarding its management during pregnancy. At present it is not possible to predict who will regress and who will progress without treatment. Some of the variation in progression of DR in pregnancy may be a result of well-known risk factors such as hypertension or inadequate glycemic control prior to pregnancy. Other pregnancy-associated retinal diseases are relatively uncommon, and their treatments are poorly characterized. Pre-existing conditions include the white dot syndromes, such as punctuate inner choroidopathy and ocular histoplasmosis syndrome, as well as chorioretinal neovascularization from many other etiologies. Retinal and chorioretinal disorders that can arise during pregnancy include central serous chorioretinopathy and occlusive vasculopathy such as retinal artery occlusion (Purtschers-like retinopathy) and retinal vein occlusion. There remains a small group that appear to be unique to pregnancy, with pre-eclampsia- and eclampsia-associated retinopathy, disseminated intravascular coagulopathy, or amniotic fluid embolism being the best described. In angiogenic retinal diseases outside of pregnancy, the use of anti-vascular endothelial growth factor (anti-VEGF agents) has proven helpful. There are no safety data about the use of anti-VEGF agents during pregnancy, and conventionally the proposed interventions have been laser photocoagulation and systemic or intravitreal injections of steroids. Most of the literature on the treatment of pregnancy associated-chorioretinal neovascularization is anecdotal.

Abstract
India leads the world with largest number of diabetics earning the dubious distinction of "the diabetes capital of the world." Diabetes is associated with maternal and perinatal morbidity and mortality. The number of pregnant women with pre-existing diabetes is increasing, mainly from an increase in type 2 diabetes, but also an increase in type 1 diabetes. Overall, type 1 diabetes accounts for approximately 5% to 10% of all diabetes outside of pregnancy, and in pregnancy put together with type 2 account for 10% of diabetic pregnancies. Management of the pregnant diabetic woman is a complex task that ideally begins before conception. Specific attention is required for diabetic pregnancies in different trimesters of pregnancy. Diabetes, especially type 1 diabetes, can be a challenge in pregnancy, but with education, close monitoring, and latest therapeutic modalities, these women can have healthy newborns. Close attention to diet, glycemic control, metabolic stresses, and early diagnosis and monitoring of complications can make pregnancy a successful experience for women with diabetes. A MedLine search was done to review relevant articles in English literature on diabetes and pregnancy, and specific issues related to pregnancy in type 1 diabetes were reviewed.

Abstract
The prevalence of preexisting diabetes in pregnancy is increasing largely because of an increase in type 2 diabetes. Outcomes of diabetic pregnancies for mother and newborn have improved greatly in recent decades from advances in understanding the disease process, improved education, and new treatment modalities delivered in a team approach. Nausea and vomiting from pregnancy and pregnancy-associated insulin resistance can make glycemic control a challenge. Care of women with preexisting diabetes demands careful monitoring in the preconception, prenatal, and peripartum periods.

Abstract
Hypertensive disorders in pregnancy can be chronic, pregestational or just diagnosed before the 20th week, or newly diagnosed in the second half of pregnancy. Any type of hypertension is more frequent in diabetic pregnancies with a different distribution among different types of diabetes. Most of the evidence is for pre-eclampsia associated with a marked increase in primary caesarean section, preterm birth and more need for neonatal intensive care. Different risk factors and pregnancy outcomes would support the hypothesis that pre-eclampsia and gestational hypertension might be largely separate entities, but this position is not unanimously accepted. Chronic hypertension increases with age and duration of diabetes, predicting increased rates of prematurity and neonatal morbidity, especially when associated with superimposed pre-eclampsia. Long-term consequences are observed in women whose pregnancy was complicated by hypertension such as chronic hypertension and cardiovascular diseases.

Abstract
Diabetic retinopathy should be carefully monitored during certain risk situations. Indeed, diabetic retinopathy in pregnant type 1 diabetic patients can rapidly progress and threaten vision, as in other situations such as puberty, glycemic equilibration, or ocular surgery. During pregnancy, five major risk factors for progression have been identified: pregnancy itself, diabetic retinopathy grade at baseline, duration of diabetes, important glycated hemoglobin reduction, and high blood pressure. These factors must be taken into account when planning pregnancy in diabetic patients and during the follow-up of their diabetic retinopathy. Diabetic women should be counseled about the risks of progression of their disease before planning pregnancy. Careful eye examination before and during the first trimester should be done in these patients, in order to detect severe non-proliferative diabetic retinopathy and/or high-risk diabetic retinopathy and perform rapid laser treatment if needed. Follow-up visit frequency should be adapted to the severity of the diabetic retinopathy. Very few authors have studied diabetic macular edema during pregnancy. This complication can spontaneously regress postpartum and should not be treated too rapidly.

Abstract
AIMS To determine the progression of diabetic retinopathy in pregnant women with diabetes offered tight glycaemic and blood pressure control. METHODS A prospective study of 102 (87%) out of 117 consecutive pregnant women with Type 1 diabetes for median 16 years (range 1-36) and HbA(1c) 6.7% (4.9-10.8) in early pregnancy. Fundus photography was performed at 8 and 27 weeks. Retinopathy was classified in five stages. Diabetic macular oedema was classified as present in a mild form or as clinically significant macular oedema (CSMO). Progression was defined as at least one stage of deterioration of retinopathy and/or development of macular oedema in at least one eye. Sight-threatening progression was defined as loss of visual acuity>or=0.2 on Snellen's chart or laser treatment performed during pregnancy due to proliferative retinopathy or CSMO. RESULTS Diabetic retinopathy was present at inclusion in at least one eye in 64 (63%) women and proliferative retinopathy and macular oedema were present in nine and 16 women, respectively. Progression of retinopathy occurred in 28 (27%) women. Sight-threatening progression occurred in six women; in three, visual acuity deteriorated and four required laser treatment. Sight-threatening progression was associated with presence of macular oedema (P=0.007), impaired visual acuity (P=0.03) and higher blood pressure (P=0.016) in early pregnancy, but not with HbA1c, decline in HbA1c, or prevalence of severe hypoglycaemia. CONCLUSIONS Loss of visual acuity and the need for laser treatment during diabetic pregnancy remain clinical problems associated with presence of macular oedema, visual impairment and higher blood pressure in early pregnancy.

Abstract
Pregnancy may be associated with several ocular changes, including the development of new ocular conditions or modifications of existing conditions. The most common ocular condition modified by pregnancy is diabetic retinopathy. Pregnancy is associated with an increased risk of development and progression of diabetic retinopathy. The factors associated with its progression include the pregnant state itself, duration of diabetes, amount of retinopathy at conception, blood glucose control, and the presence of coexisting hypertension. Although the rate of regression of diabetic retinopathy at the end of pregnancy or the postpartum period is high, careful monitoring of these patients is necessary to optimize the vision and pregnancy outcomes.

Abstract
PURPOSE The incidence and risk factors for progression of retinopathy during pregnancy in women with type 1 diabetes mellitus were retrospectively evaluated. METHODS Fifty-four insulin-dependent diabetic patients at a teaching hospital in Saudi Arabia were followed throughout the pregnancy/puerperium with serial ophthalmic examination. Dilated fundus examination was performed in each trimester and puerperium. RESULTS Progression of diabetic retinopathy in the study occurred in 13/54 (24%) patients--2/22 (9.1%) patients had no diabetic retinopathy initially, 4/20 (20%) had non-proliferative diabetic retinopathy (NPDR) and 7/12 (58.3%) had proliferative diabetic retinopathy (PDR). Of the eight patients with PDR who had no laser treatment before pregnancy, six (75%) showed progression but only one of the four patients who had PDR and laser treatment prior to pregnancy experienced progression of retinopathy. Eight patients in total received panretinal photocoagulation to arrest the progression of retinal disease during pregnancy and only one of them had laser treatment prior to pregnancy. CONCLUSION Laser photocoagulation for severe NPDR or early PDR prior to pregnancy may protect against rapid progression of PDR. Visual impairment resulting from progression of PDR can be prevented by aggressive laser treatment during pregnancy. Duration of diabetes>15 years, poor glycaemic control and hypertension are high-risk factors in the progression of diabetic retinopathy in pregnancy.

Abstract
AIMS/HYPOTHESIS Our aim was to study whether pre-eclampsia and pregnancy-induced hypertension are predictors of diabetic nephropathy in type 1 diabetic women. MATERIALS AND METHODS A total of 203 type 1 diabetic women, who were pregnant between 1988 and 1996 and followed at the Department of Obstetrics and Gynaecology in Helsinki, were re-assessed after an average of 11 years within the nationwide, multi-centre Finnish Diabetic Nephropathy Study. Diabetic nephropathy was defined as microalbuminuria, macroalbuminuria or end-stage renal disease. RESULTS Patients with prior pre-eclampsia had diabetic nephropathy more often than patients with a normotensive pregnancy (diabetic nephropathy vs normal albumin excretion rate: 41.9% vs 8.9%; p<0.001), whereas patients with a history of pregnancy-induced hypertension did not (10.3% vs 8.9%; p=0.81). CHD was more prevalent in patients with a history of pre-eclampsia than in patients with a normotensive pregnancy (12.2% vs. 2.2%; p=0.03). Pre-eclampsia (odds ratio [OR] 7.7, 95% CI 1.6-36.1; p=0.01) and HbA(1c) (OR 2.0, 95% CI 1.1-3.8; p<0.05) were associated with incident diabetic nephropathy even when adjusted for follow-up time, BMI, smoking, diabetes duration and age. CONCLUSIONS/INTERPRETATION These data suggest that a history of pre-eclamptic pregnancy but not pregnancy-induced hypertension is associated with an elevated risk of diabetic nephropathy.

Abstract
Without strict glycemic control, diabetic pregnancies are frequently complicated by spontaneous abortion, stillbirth, or congenital malformation. Retrospective studies have been largely reassuring that pregnancy does not accelerate morbid outcomes in women with diabetic vascular disease. Improved outcomes of high-risk pregnancy in women with pregestational, type 1, or type 2 diabetes mellitus remain challenging, depending on a comprehensive and multidisciplinary team approach and extensive preconception counseling.

Abstract
During the past decades our understanding about the clinical impact of diabetes has changed. We now know for certain that a good (read : near normal) glycemic control is necessary to prevent chronic complications of this disease in women regardless of the type of diabetes. Pregnancy is a specific situation whereby a "near normal" control is wanted not only for the patient but also for the fetus. Several studies have shown a correlation beween glycemic control and complications of pregnancy. Reaching optimal glycemic control is mandatory even before the pregnancy starts, considering the time window of occurance of the severe foetal congenital malformations (first weeks of pregnancy). The role of pre-conception care is emphasized. Optimal control in type 1 and type 2 diabetic patients can best be reached through intensive insulin therapy, but reaching normoglycemia is mainly limited by the occurence of hypoglycemia. The introduction of the new insulin analogues is an important step in our arsenal to achieve control using multiple daily insulin injections, but Novorapid and Lantus have not yet been approved for use in pregnancy. Insulin pumps are often used in pregnant patients, allowing an even better glycemic control with less hypoglycemia. An absolute requirement for CSII therapy to be successful is patient education and motivation by an experienced team.

Abstract
OBJECTIVE To evaluate the progression of retinopathy during pregnancy and postpartum in (insulin-dependent) women with type 1 diabetes treated with insulin lispro or with regular human insulin. RESEARCH DESIGN AND METHODS A prospective open study of 69 pregnant women with diabetes was performed. A total of 36 of the women were treated with insulin lispro (lispro group) and 33 were treated with conventional short-acting human insulin (regular insulin group). The retinopathy level was estimated by color fundus photography every trimester and postpartum. Glycemic control during pregnancy, hypoglycemia (blood glucose level <3 mmol/l) in 24-h glucose profile, blood pressure, and proteinuria were registered. RESULTS HbA(1c) values were similar at baseline in the first trimester but thereafter were lower in the lispro group than in the regular insulin group throughout pregnancy (P = 0.022, repeated-measures ANOVA). The number of hypoglycemic episodes did not differ between the treatment groups. In multivariable logistic regression analysis with retinopathy severity (Diabetes Control and Complications Trial level) in the third trimester as the dependent variable, only nulliparity qualified as a predictor in the model [Exp(B) = 4.0, 95% CI 1.1-13.7, P = 0.030]. Factors such as duration of diabetes, type of insulin used, mean HbA(1c) level throughout pregnancy, blood pressure (systolic or diastolic), preeclampsia in the current pregnancy, smoking, or prepregnancy planning did not explain the retinopathy progression. CONCLUSIONS Insulin lispro improves glycemic control during diabetic pregnancy compared with regular insulin with no adverse impact on progression of diabetic retinopathy.

Abstract
UNLABELLED Visual changes in pregnancy are common, and many are specifically associated with the pregnancy itself. Serous retinal detachments and blindness occur more frequently during preeclampsia and often subside postpartum. Pregnant women are at increased risk for the progression of preexisting proliferative diabetic retinopathy, and diabetic women should see an ophthalmologist before pregnancy or early in the first trimester. The results of refractive eye surgery before, during, or immediately after pregnancy are unpredictable, and refractive surgery should be postponed until there is a stable postpartum refraction. A decreased tolerance to contact lenses also is common during pregnancy; therefore, it is advisable to fit contact lenses postpartum. Furthermore, pregnancy is associated with a decreased intraocular pressure in healthy eyes, and the effects of glaucoma medications on the fetus and breast-fed infant are largely unknown. TARGET AUDIENCE Obstetricians & Gynecologists, Family Physicians. LEARNING OBJECTIVES After completion of this article, the reader will be able to list the various ocular changes that occur during pregnancy, summarize the ocular disturbances that occur with preeclampsia and diabetes, and describe the management of some ocular problems during pregnancy.

Abstract
AIMS To evaluate the impact of pregnancy on the progression of diabetic retinopathy in women with Type 1 diabetes mellitus and to identify risk factors for the progression of retinopathy during pregnancy. METHODS One hundred and seventy-nine pregnancies in 139 women with pregestational Type 1 diabetes were studied prospectively between January 1990 and December 1998. Dilated fundal examination was performed at booking, 24 weeks and 34 weeks or 4-6 weekly if retinopathy present at booking. Data were collected on glycaemic control (HbA(1c)) throughout pregnancy. RESULTS Progression to proliferative retinopathy was seen in four (2.2%) pregnancies while moderate progression was seen in a further five (2.8%) pregnancies. Progression of retinopathy was significantly increased in women with duration of diabetes 10-19 years compared with duration < 10 years (10% vs. 0%; P = 0.007) and in women with moderate to severe background retinopathy at booking (30% vs. 3.7%; P = 0.01). Although HbA(1c) at booking was higher (7.5% vs. 6.6%; P = 0.08) and the fall in HbA(1c) between booking and 24 weeks was greater (1.6% vs. 1.2%; P = 0.2) in those women showing progression of retinopathy, these changes were not significant. CONCLUSIONS Progression of retinopathy in pregnancy was uncommon (5.0% pregnancies) but was significantly more common in women with duration of diabetes > 10 years and in women with moderate to severe retinopathy at baseline. Laser therapy was needed in 2.2% pregnancies, which is much lower than that reported in earlier studies. Diabet. Med. 18, 573-577 (2001)

Abstract
OBJECTIVE To assess the effect of pregnancy on the development and progression of retinopathy and microalbuminuria in type 1 diabetes. RESEARCH DESIGN AND METHODS We conducted longitudinal analyses of the Diabetes Control and Complications Trial (DCCT), a multicenter controlled clinical trial that compared intensive treatment with conventional diabetes therapy and studied 180 women who had 270 pregnancies and 500 women who did not become pregnant during an average of 6.5 years of follow-up. Women assigned to the conventional treatment group were changed to intensive therapy if they were planning pregnancy or as soon as possible after conception. Fundus photography was performed every 6 months, and the urinary albumin excretion rate (AER) was measured annually. RESULTS Compared with nonpregnant women, pregnant women had a 1.63-fold greater risk of any worsening of retinopathy from before to during pregnancy (P < 0.05) in the intensive treatment group; the risk was 2.48-fold greater for pregnant vs. not pregnant women in the conventional group (P < 0.001). In the conventional group, the odds of > or =3-step progression from the baseline retinopathy level was >2.9-fold among pregnant vs. not pregnant women (P = 0.003). The odds ratio (OR) peaked during the second trimester (OR = 4.26, P = 0.001) and persisted as long as 12 months postpregnancy (OR = 2.87, P = 0.005). The level of AER during pregnancy in the intensive group, but not in the conventional group, was significantly elevated from the level at baseline, albeit in the normal range. Although individual patients had transient worsening of retinopathy during pregnancy, even to the proliferative level, at the end of the DCCT, mean levels of retinopathy and albuminuria in subjects who had become pregnant were similar to those in subjects who had not become pregnant within each treatment group. CONCLUSIONS Pregnancy in type 1 diabetes induces a transient increase in the risk of retinopathy; increased ophthalmologic surveillance is needed during pregnancy and the first year postpartum. The long-term risk of progression of early retinopathy and albumin excretion, however, does not appear to be increased by pregnancy.
