PURPOSE: To perform a glaucoma work-up in infants with congenital Zika syndrome (CZS). PATIENT AND METHODS: This cross-sectional study included 188 eyes of 107 children (1.1 ± 0.3▒y [range, 0.3-1.8▒y]) with CZS. The confirmation of the syndrome was possible in 77/107 (72.0%) of the enrolled infants based on positive immunoglobulin M antibody capture enzyme-linked immunosorbent assay for Zika virus in the cerebrospinal fluid. All infants underwent a complete ophthalmic examination and bilateral fundus imaging was captured using a wide-angle digital fundus camera (RetCam™; Natus Medical Inc...

To report observations of horizontal corneal diameter (HCD) and central corneal thickness (CCT) changes in premature infants with stable optic disc cupping and intraocular pressures (IOPs). The HCD and CCT at term serve as a baseline for premature infants.Sixty-three premature infants were enrolled in a prospective case series. HCD, CCT, and IOP were measured. RetCam images of the optic discs were used to evaluate the cup-disc ratio (CDR) and read by an independent masked observer. Data were collected at between preterm (32-36 weeks) and again at term (37-41 weeks) postconceptual age...

BACKGROUND: The prevalence of ocular abnormalities of newborn in China has seldom been reported. To report the implementation of digital imaging in ocular screening of all newborns in multiple centres in China and to describe the abnormal findings of fundus examination, we did the cross-sectional study. METHODS: Fundus examinations were performed on newborns within the 42 days after birth using a RetCam wide-field digital imaging system. Digital images of the posterior pole, superior, nasal and temporal retinal fields of each participant were taken...

Retinopathy of Prematurity (ROP) is a retinal vasproliferative disorder disease principally observed in infants born prematurely with low birth weight. ROP is an important cause of childhood blindness. Although automatic or semiautomatic diagnosis of ROP has been conducted, most previous studies have focused on "plus" disease, which is indicated by abnormalities of retinal vasculature. Few studies have reported methods for identifying the "stage" of ROP disease. Deep neural networks have achieved impressive results in many computer vision and medical image analysis problems, raising expectations that it might be a promising tool in automatic diagnosis of ROP...

OBJECTIVES: To evaluate the diagnostic accuracy of a digital fundus photographic system that consists of taking fundus photographs by a trained technician using a RetCam® shuttle and interpreting fundus images by an expert to detect Retinotapthy of Prematurity requiring treatment (ROP-RT) which defined as type I ROP according to the Early Treatment for ROP study (ETROP). MATERIALS AND METHODS: One hundred infants were examined by (1) an expert ophthalmologist experienced in ROP care using indirect ophthalmoscopy; (2) digital wide-field imaging by a trained technician using a RetCam® shuttle and images were sent remotely for interpretation by two ophthalmologists experienced in ROP care (Reader A, and Reader B); and (3) local ophthalmologists using indirect ophthalmoscopy...

BACKGROUND AND OBJECTIVE: To determine whether retinopathy of prematurity (ROP) that persists beyond a postmenstrual age (PMA) of 45 weeks has abnormalities that can be documented by fundus photography or fluorescein angiography (FA). PATIENTS AND METHODS: Fundus photographs and FAs were reviewed for all premature infants who underwent FA for persistent ROP after 45 weeks PMA. RESULTS: Of the 487 infants who were screened for ROP, 16 (3.3%) demonstrated ROP beyond 45 weeks...

BACKGROUND: Retinal hemorrhage (RH) is one of the hallmarks of abusive head trauma (AHT); however, RH is also encountered with normal vaginal deliveries (NVD) and thus presents the clinician with a diagnostic dilemma. The purpose of this study was to compare RHs in AHT with those of NVD. METHODS: Records of with AHT and NVD infants with RH evaluated from 2013 to 2015 were reviewed retrospectively. Pattern, size, extent, and severity were compared using RetCam images...

PURPOSE: To design software with a novel algorithm, which analyzes the tortuosity and vascular dilatation in fundal images of retinopathy of prematurity (ROP) patients with an acceptable accuracy for detecting plus disease. METHODS: Eighty-seven well-focused fundal images taken with RetCam were classified to three groups of plus, non-plus, and pre-plus by agreement between three ROP experts. Automated algorithms in this study were designed based on two methods: the curvature measure and distance transform for assessment of tortuosity and vascular dilatation, respectively as two major parameters of plus disease detection...

PURPOSE: We sought to document the difference in the vitreoretinal configuration of Stage 4 retinopathy of prematurity (ROP) in photocoagulated and treatment naive eyes undergoing vitrectomy and to correlate it with surgical complexity. METHODS: Consecutive eyes posted for vitrectomy with Stage 4 ROP were documented preoperatively using a RetCam for the presence of peripheral traction (PT), presence of central traction just outside the arcades, and presence of traction extending to the lens...

OBJECTIVE: To analyze posterior segment findings in term and premature infants using the RetCam image database. METHODS: RetCam images taken of infants born between January 2012 and December 2015 were reviewed. Group 1 included infants with posterior segment findings other than retinopathy of prematurity (ROP). Group 2 included infants with mild-to-severe ROP. The baseline characteristics, anterior segment findings, and percentage of infants who received treatment were compared among the 2 groups...

PurposeTo investigate whether the observed international differences in retinopathy of prematurity (ROP) treatment rates within the Benefits of Oxygen Saturation Targeting (BOOST) II trials might have been caused by international variation in ROP disease grading.MethodsGroups of BOOST II trial ophthalmologists in UK, Australia, and New Zealand (ANZ), and an international reference group (INT) used a web based system to grade a selection of RetCam images of ROP acquired during the BOOST II UK trial. Rates of decisions to treat, plus disease grading, ROP stage grading, ROP zone grading, inter-observer variation within groups and intra-observer variation within groups were measured...
