Visual outcomes and complications of congenital cataract surgery

Corresponding author at: Department of Ophthalmology, 14, rue Paul-Gaffarel, 21000 Dijon, France. This work is issued from the oral presentation during the 123rd congress of the French Ophthalmological Society.International audiencePURPOSE: To describe the visual results and postoperative complications of congenital cataract surgeries performed between 2005 and 2016. METHODS: A retrospective consecutive case series of congenital cataract surgeries was carried out at the Dijon University Hospital in France. Intraocular lens implantation was primary or secondary according to age. Pre- and post-operative assessment was performed through ophthalmologic consultations with orthoptic measurements. Visual function and adverse events were recorded. RESULTS: Fifty-six consecutive procedures were evaluated in 37 infants. Overall, 26.8% of patients had unilateral cataracts, and 73.2% had bilateral cataracts. Median age at surgery was 1.0 years [IQR (interquartile range): 0.3-5.2] and 2.7 years [IQR: 0.4-9.5] for unilateral and bilateral cataracts, respectively. Median best-corrected visual acuity (BCVA) at the last follow-up was 0.5logMAR [IQR: 0.2-0.8] and 0.1logMAR [IQR: 0.0-0.8] for the unilateral and bilateral group, respectively. Posterior capsule opacification (PCO) was the primary postoperative complication: 60.0% in unilateral cataract and 46.3% in bilateral cataracts (P=0.019). Median follow-up was 2.0 years [IQR: 1.0-5.0]. CONCLUSION: Congenital cataract surgery appears to be safe and effective when combined with early, conscientious amblyopia treatment. Bilateral congenital cataracts had better visual outcome than unilateral cataract

Retinopathy of prematurity screening: evaluation of a first screening

Purpose: Retinopathy of prematurity (ROP) screening concerns preterm infants born before 32 weeks of amenorrhea and/or weighting less than 1500 grams. First screening occurs usually 4 to 6 weeks after birth and always after 31 weeks of amenorrhea. The purpose of this study was to investigate the number of examinations performed before the first signs of retinopathy, in order to determine the best time for first screening.Methods: This retrospective study enrolled preterm infants born before 32 weeks of amenorrhea and/or weighting less than 1500 grams in the University Hospital of Dijon, France, between 11/15/2012 and 12/31/2013. All preterm babies benefited from a ROP screening by fundus photography with a wide field camera. First screening was realized 4 to 6 weeks after birth and after 31 weeks of amenorrhea. All photographs were analysed. Population characteristics, number of examinations before first signs of retinopathy, term at first examination, at first signs of retinopathy and at the most severe signs of retinopathy were noted.Results: Hundred and eight preterm infants were enrolled; 33 were affected by ROP. Median [IQR] term was 29.6 [27.0 ; 31.0] weeks of amenorrhea. Median weight was 1118 [915 ; 1431] grams. Median number of examinations in preterm infants with ROP was 7 [4 ; 9]. Median term at first screening, at first signs of retinopathy and at more severe signs of retinopathy were 31.7 [30.9 ; 32.1], 33.7 [32.3 ; 35.0], 36.9 [35.6 ; 37.9] weeks of amenorrhea, respectively. Median number of examinations before first signs of retinopathy was 1 [1 ; 2]. In 25 preterm infants weighting less than 1000 grams, median term at first signs of retinopathy was 33.3 [32.3 ; 34.6], versus 34.8 [34.3 ; 35.2] in 8 preterm infants weighting more than 1000 grams (p=0.03).Conclusions: In ROP, the time of first screening is not well defined. According to our series, a first screening at 33 weeks of amenorrhea seems optimal

Prevalence of age-related macular diseases in an old French population (the MONTRACHET Study)

National audiencePurpose To describe the prevalence of age‐related macular diseases in a French population‐based study (the Montrachet study) older than 74 years. Methods The Three City study (3C) was a prospective study including 9294 patients aged of 65 years or more from three French cities (Dijon, Bordeaux, and Montpellier) at enrolment in 1999. After 10 years of follow‐up, an eye examination was proposed to participants of the 3C cohort in Dijon and 1153 participants were included in the so‐called Montrachet study. All patients underwent a complete eye examination including nonmydriatic color retinal photographs. The photographs were classified according to the type of abnormality (intermediate soft drusen, large soft distinct or indistinct drusen, reticular drusen or large area of soft drusen reaching 500 µm in diameter, hyperpigmentation or hypopigmentation), and their location (central or pericentral) using the classification of the Multi‐ethnic Study of Atherosclerosis (MESA) and that used in the Rotterdam Study. Patients were then classified into 3 categories: early age‐related macular degeneration (AMD), late AMD (atrophic or neovascular). Results Data were available for 1069 patients: 396 men (37.0%) and 673 women (63.0%). The mean age was 82.2 ± 3.8 years. The prevalence of healthy subjects was 56.0%. Stages 1, 2 and 3 accounted for 32.6%, 7.7% and 1.5%, respectively. The late AMD stages represented 2.2% (24 patients). Smoking was not significantly associated with AMD categories. Conclusions The prevalence of AMD grading in our population is consistent with the literature. The classification of participants according to different macular abnormalities may predict the populations at risk of developing an advanced grade and can help to adapt the management. The relationship with other risk factors will be the next step of this analysis

Screening for retinopathy of prematurity: Insight into optimizing screening

International audiencePurpose: To determine the factors influencing the time from preterm birth and retinopathy of prematurity (ROP) detection to optimize the timing of the initial screening. Methods: This multicenter retrospective study enrolled preterm infants born before 32 weeks of gestational age (GA) and/or weighing less than 1,500 g between January 1, 2011, and December 31, 2015. ROP screening was performed using fundus photography with a wide-field camera. Population a nd follow-up characteristics were recorded. Results: Among the 1,266 preterm infants observed, 795 were retained for analysis. One hundred seventy-four (21.6%) cases of ROP were detected with the first examination performed at 32.3 +/- 1.6 weeks of postmenstrual age (PMA) and 5.4 +/- 1.0 weeks of postnatal age (PNA). The first signs of ROP were detected at 34.0 +/- 1.9 weeks of PMA and 7.2 +/- 1.8 weeks of PNA, respectively. In the multivariate analysis, an older GA, a longer duration of mechanical ventilation, and a lower birth weight were correlated with a longer time between preterm birth and ROP detection (p < 0.0001, p < 0.0001, and p = 0.0359, respectively). Conclusion: The first examination for ROP screening should be individualized to fit the first screening examination as closely as possible to the first signs of ROP in order to avoid unnecessary examinations without missing ROP
