Management of severe persistent fetal vasculature: case series and review of the literature.

PURPOSE: Persistent fetal vasculature (PFV) is a unique ocular disorder usually presenting early in life. The unregressed embryonal hyaloid vasculature poses a risk of severe ocular complications leading to decreased visual acuity. Surgery is the mainstay of therapy in complicated cases. We describe the clinical presentation and surgical treatment of PFV managed at our center from 2012 to 2015. METHODS: The study is a case series comprised eight patients who were diagnosed with complicated severe PFV. All were managed with a tailored surgical approach. The clinical characteristics, medical and surgical treatment, and follow-up findings of each case are described. RESULTS: There were six males and two females. Surgical intervention involved anterior or posterior vitrectomy, lens extraction, and intraocular lens implantation. Hyaloid stalk removal with release of ciliary traction was variably utilized in selected cases. Endodiathermy controlled intraocular bleeding, and intraocular scissors proved helpful in anterior PFV for disinserting the ciliary process from an abnormally thickened posterior lens capsule. Visual outcomes differed in each case, depending on multiple clinical factors. CONCLUSION: Severe complex PFV presents a therapeutic challenge. A tailored surgical approach with meticulous postoperative management is essential for visual rehabilitation.

Analysing the ocular biometry of new-born infants.

PURPOSE: To model and analyse the ocular biometry of new-born infants. METHODS: This work is based on previously published data of a cohort of 66 new-born infants aged 0-3 days. After exclusion of seven myopic subjects, the available retinoscopy, keratometry and ultrasound biometry data were analysed, along with calculated parameters such as lens power and whole eye power. RESULTS: Male infants have significantly flatter corneas that female infants (Mann-Whitney U test, p < 0.001), which was associated with a difference in gestational age between genders (multiple linear regression; p = 0.043). No other gender-based differences were seen. Corneal curvature (Pearson, r = 0.575; p < 0.001), lens power (r = -0.681; p < 0.001), and anterior chamber depth (r = 0.654; p < 0.001) were all correlated to axial length, but not refraction (r = -0.114; p = 0.42). Most ocular parameters were associated with gestational age (linear regression analysis; p < 0.05), rather than birth length, birth weight, fertilization method or parental myopia (all p > 0.05), suggesting scaled eye growth during the last weeks before birth. Multivariate Gaussian analysis demonstrated that a statistical eye model can be defined that generates synthetic data that is significantly equal to the original data (non-parametric Mann-Whitney test for equality; all p < 0.05), with similar variability (non-parametric Levene test; all p > 0.05). CONCLUSION: The eye undergoes a scaled growth until birth, at which time male and female infants have similar values. The models presented may serve as an early biometry reference.

Difficulty in Distinguishing Posterior Reversible Encephalopathy Syndrome, Hypoxic-Ischemic Insult, and Acute Toxic Leukoencephalopathy in Children.

AIM: This study aims to describe our experience of unique pediatric neurological cases and associated difficulty in differentiating posterior reversible encephalopathy syndrome (PRES) from hypoxic-ischemic insult (HII), and acute toxic leukoencephalopathy (ATL). METHODS: The study included three children with a clinical picture suggestive of PRES, HII, and ATL of different etiologies who were diagnosed and treated at a tertiary pediatric medical center in 2011 to 2014. RESULTS: All patients presented with blindness following seizures with asphyxia/aspiration in a syndromatic child, too-rapid lipid infusion in a child with acute lymphoblastic leukemia, and repeated vomiting in a child with cerebral palsy, hydrocephalus, and malfunction of ventriculoperitoneal shunt. All patients had cortical blindness and high-signal foci in the cortical and subcortical regions on magnetic resonance imaging. All children improved. CONCLUSIONS: Familiarity with the clinical and radiological characteristics of neurological conditions leading to reversible cortical blindness is essential for diagnosis and management. Distinguishing PRES from HII and ATL can be challenging. Our cases most likely combined these etiologies, with the first patient diagnosed with PRES with HII, the second with PRES with ATL, and the third with focal HII. Given the diversity of the findings and the unclear prognostic significance, studies of the pathophysiology of PRES are warranted.

Medical And Surgical Management Of Orbital Cellulitis In Children.

OBJECTIVE: The purpose of this study was to identify features of orbital cellulitis that predict response to conservative treatment without surgical intervention and factors associated with a decision for surgery. PATIENTS AND METHODS: The medical files of patients diagnosed with orbital cellulitis at a tertiary medical center in central Israel between 1995 and 2010 were reviewed for clinical data, diagnosis, complications, and type of treatment. Comparison was made between patients treated with antibiotics and patients treated with antibiotics and surgery. RESULTS: Fifty-one patients (35 male) with a mean age of 6.1 years were identified. Main clinical signs included fever (mean 38.5°C), proptosis (82.3%), extraocular motility restriction (74.5%), and ocular pain (41.1%). Forty-one patients were successfully treated with antibiotics and 10 required endoscopic sinus surgery. On between-group comparison, the surgery group had severe eye pain (p = 0.009), severe proptosis (P = 0.02), longer intravenous antibiotic treatment (13.2 vs. 9.2 days, p = 0.04), and several imaging findings. Additional factors associated with surgical intervention included older children, subperiorbital abscess, larger dimension of the abscess (mean 15 mm), involvement of frontal sinuses and findings of intraorbital air bubbles. There was no visual deterioration in either group and no late sequelae. CONCLUSION: Factors associated with surgery included age older than 9 years, severe ocular pain, severe proptosis, and subperiorbital large abscess. These may be used for early identification of patients at risk of failure of only medical management.

Intravitreal bevacizumab as supplemental treatment or monotherapy for severe retinopathy of prematurity.

PURPOSE: To investigate the benefit of intravitreal bevacizumab as supplemental or primary treatment for retinopathy of prematurity. METHODS: The files of nine consecutive infants treated with intravitreal bevacizumab for bilateral severe posterior retinopathy of prematurity were reviewed. RESULTS: Gestational age was 24 weeks to 27 weeks, and birth weight was 660 g to 1,131 g. Indications for treatment were retinopathy of prematurity progression from Stage 3 to 4A or 2 to 3 with extraretinal neovascularization despite laser treatment; active neovascular Stage 4A disease after laser and cryo-treatment; anterior segment neovascularization and bleeding after laser treatment; and aggressive posterior disease with tunica vasculosa lentis and vitreous haze, which prevented laser treatment. One patient (two eyes) underwent lens-sparing vitrectomy after bevacizumab treatment; one eye acquired macular fold. One patient underwent bilateral scleral buckle. Bevacizumab treatment was associated with subsidence of the active vascular component in all eyes. Anatomical results were favorable in 17 eyes. There were no local or systemic complications. CONCLUSION: Intravitreal bevacizumab may serve as a supplemental therapeutic agent for severe laser-refractory retinopathy of prematurity or as monotherapy when media opacities preclude diode laser photocoagulation or the patient is too sick for lengthy laser treatment.

Ocular complications in children and adolescents following renal transplantation.

Ocular complications after renal transplantation are common in adults. Nevertheless, data regarding these complications in children are insufficient. The purpose of the present study was to assess ocular morbidity in pediatric renal graft recipients. A retrospective observational study of 71 patients aged 11.2 +/- 5.5 yr was conducted. Mean duration of follow-up was 5.6 +/- 3.5 yr. A total of 16 ocular complications were found in 12 (17%) of the patients. Three patients suffered from more than one complication. Cataract was the most common finding (six patients, 8.4%) followed by swollen disk and hypertensive retinopathy in four patients (5.7%) each and increased intra-ocular pressure in two patients (3%). Mean time interval between transplantation and occurrence of first abnormal ocular finding was 37 +/- 34.5 months. The follow-up time was significantly longer in patients with ophthalmological problems than in those without complications (7.8 yr vs. 5.2 yr, p < 0.02). No statistically significant association was found between the occurrence of ocular complications and the age of the patients at transplantation, donor source, duration of dialysis prior to transplantation, previous corticosteroid therapy or presence of acute rejection episodes. The results of the study point to the importance of regular concurrent ophthalmological follow-up in pediatric renal graft recipients to reduce/prevent ocular morbidity.

Evaluation of ocular motility deviation changes in exotropic patients after cycloplegic eye drops versus prism adaptation test.

PURPOSE: To evaluate changes in ocular motility deviation with cycloplegic eye drop examination compared to the prism adaptation test in patients with strabismus. METHODS: The medical charts were reviewed of all patients who underwent primary strabismus surgery in our center from December 2013 to July 2015. Data collected included demographics, medical history, and findings on pre-operative ophthalmic/orthoptic examination. Ocular motility deviation was measured before instillation of cycloplegic eye drops, immediately after maximal dilation (end point), and 10 and 20 min later. Prism adaptation test readings were taken at baseline, immediately after prism removal (end point), and 10 and 20 min later. RESULTS: A total of 43 patients had complete pre- and post-operative evaluations. Our analysis focused only on the exotropic patients (n = 33). On cycloplegics, there was no significant difference in ocular motility deviation between baseline and end point for distance and near (p = 0.584, p = 0.468, respectively). On prism adaptation test, comparison of ocular motility deviation between baseline and end point was statistically significant for distance and near (p = 0.002, p = 0.001, respectively). Changes remained significant 10 min after the end point for near (p = 0.011). Comparison at the end points between the tests revealed statistical significance for distance and near, favoring the prism adaptation test (p = 0.001 and p < 0.001, respectively). This significance was maintained even after 10 min for near (p = 0.036). CONCLUSION: The prism adaptation test is preferred over cycloplegic eye drops for the evaluation of maximal reserve of distance/near motility before surgical correction of exotropia.

Horizontal Deviations in Congenital Brown Syndrome.

PURPOSE: To report the incidence of horizontal deviations requiring surgical correction in patients with congenital Brown syndrome. METHODS: In a retrospective study, the medical records of all children who underwent a surgical correction of congenital Brown syndrome at Schneider Children's Medical Center of Israel from 1998 to 2016 were reviewed, analyzing the presence of preoperative primary position horizontal misalignment. RESULTS: Overall, 19 eyes (8 right and 11 left eyes) of 16 patients (7 males, 9 females; mean age: 4.2 ± 2.6 years) were included in this study. Fourteen patients (88%) had surgery for correction of a compensatory head position, including 8 patients (50%) with a head tilt and 6 patients (38%) with a chin-up position, and 2 patients had surgery for primary position hypotropia. All of them underwent a weakening procedure of the superior oblique tendon, by either Z-tenectomy (81%, n = 13) or suture elongation of the superior oblique tendon (19%, n = 3). Fifty-six percent of patients (n = 9) had primary position horizontal deviation before surgery, including 50% (n = 8) exodeviations, ranging from exophoria of 4 prism diopters (PD) to exotropia of 30 PD, and one esotropia of 14 PD. Fifty percent of patients (n = 8) had surgery to correct the horizontal deviation by a recession of either one (31%, n = 5) or two (19%, n = 3) muscles. Mean preoperative horizontal deviation (9.3 ± 3.4 PD) decreased significantly following surgery (1.7 ± 1 PD, P = .001) (paired t test). CONCLUSIONS: Significant horizontal misalignment is often present in patients with congenital Brown syndrome and its correction should be considered at the time of surgery.

Early structural status of the eyes of healthy term neonates conceived by in vitro fertilization or conceived naturally.

PURPOSE: To evaluate the effects of in vitro fertilization (IVF) on early development of the eye in full-term healthy infants. METHODS: A case-control study was performed. The study sample included full-term infants born from March 1 to August 14, 2006, in the Neonatal Department of Helen Schneider Women's Hospital, Rabin Medical Center. Data were collected on sex, gestational age, birth weight, Apgar score, head circumference, body length, and mode of conception (IVF/natural). A full ophthalmologic examination was performed, including measurement of intraocular pressure, keratometry, ultrasound biometry, pachymetry, and funduscopy. RESULTS: Sixty-six infants (132 eyes) were examined; 32 were conceived by IVF, and 34 were conceived naturally. Girls accounted for 56% of the IVF group and 44% of the natural conception group. There were no statistically significant differences between the groups in sex, gestational age, head circumference, intraocular pressure, axial length, anterior chamber depth, and lens thickness. The IVF infants had lower birth weight and body length than the infants born by natural conception (P = 0.032, t-test). Their keratometric and pachymetric values were also higher, but when birth weight and length were controlled, this difference remained statistically significant only for infants with a birth weight of less than 3000 g and a body length of less than 48.5 cm. CONCLUSIONS: IVF apparently has no effect on early development of the eyes in full-term infants. The steeper corneal curvature and greater central corneal thickness in a subset of smaller IVF infants may reflect delayed corneal maturation.

Retinopathy of prematurity in assisted versus natural conception and singleton versus multiple births.

OBJECTIVES: To determine whether the incidence and severity of retinopathy of prematurity (ROP) differs between infants conceived naturally and those born after assisted conception, and to analyze the impact of singleton versus multiple gestation on ROP. DESIGN: Comparative case series. PARTICIPANTS: The study group consisted of 363 infants with a birth weight (BW) of < or =1500 g who were hospitalized in the neonatal unit of a single tertiary-care center between 1998 and 2000. METHODS: Data on gestational age (GA), BW, type of pregnancy (singleton/multiple), and type of conception (natural/assisted) were recorded, in addition to the ophthalmological results. Ophthalmological examinations were performed routinely at 4 weeks and repeated later, depending on the severity of the findings. MAIN OUTCOME MEASURES: Presence and stage of ROP were compared between infants conceived naturally and those conceived by assisted technology, and between singleton and multiple-birth infants. RESULTS: Mean GA at birth was 29.4 weeks (standard deviation, 2.5; range, 23-36). Two hundred four neonates (56.2%) were conceived naturally and 159 were conceived by assisted conception, either in vitro fertilization (IVF) alone (n = 119 [32.85%]) or IVF combined with drug treatment (n = 40 [11%]). Sixty-four infants in the natural conception group were the product of multiple pregnancies, as were 103 infants in the assisted conception group. Retinopathy of prematurity was noted in 159 of 363 infants (43.8%): 89 conceived naturally (71% singletons, 28% twins, and 17% triplets) and 70 born by assisted conception (70% singletons, 47% twins, and 33% triplets). There was no significant difference in either occurrence or severity of ROP between the natural conception and assisted conception groups. Singletons had a significantly higher rate of advanced ROP (stages II-III) (30.2%) than twins (23.1%), triplets, and quadruplets (10.6%) (P = 0.024). On multiple regression analysis, low GA and BW were the variables most significantly associated with ROP. CONCLUSIONS: In our sample, assisted conception per se did not appear to be a risk factor for ROP. Singleton babies with a birth weight of < or =1500 g were more prone to develop ROP stages II and III than twins or triplets. Gestational age and BW were the most significant factors associated with ROP.

Surgical and functional results of augmented superior oblique muscle z-tenotomy in patients with superior oblique overaction and Brown's syndrome.

BACKGROUND AND OBJECTIVE: To compare the effectiveness of augmented superior oblique Z-tenotomy (SOZT) with fixed standard SOZT in canceling preoperative superior oblique overaction associated with A pattern anisotropia or V pattern in Brown's syndrome. PATIENTS AND METHODS: Sixteen consecutive patients with superior oblique overaction or Brown's syndrome were treated by removal of a triangular piece of the superior oblique tendon near its insertion (augmented SOZT). Outcome was compared with 20 consecutive historical controls after standard SOZT. RESULTS: The decrease in superior oblique overaction in the right and left eyes and fundus intorsion and the collapse of A pattern anisotropia were more significant for patients with superior oblique overaction (P = .003, P = .007, P = .05, P = .0015, respectively) and patients with Brown's syndrome (P = .025, P = .03, and P = .05, respectively). No study patient with superior oblique overaction and A pattern anisotropia required reoperation compared with 5 of 14 controls (37.5%); rates for patients with Brown's syndrome were 0 for the study group and 3 of 6 (50%) for the control group. CONCLUSIONS: Augmented SOZT is superior to standard SOZT for correcting superior oblique overaction, intorsion, A or V pattern, and stereopsis. It is not associated with complications or reoperation. The size of the Z-tenotomy can be modified according to the intraoperative assessment to achieve symmetric results.

Insulinlike growth factor I affects ocular development: a study of untreated and treated patients with Laron syndrome.

OBJECTIVE: To evaluate the ocular dimensions in patients with primary growth hormone receptor insensitivity (Laron syndrome [LS]) and to study the effect of supplemental insulinlike growth factor I (IGF-I) on ocular growth. DESIGN: Retrospective case series. PARTICIPANTS: Twelve patients with LS, 8 untreated (LS group) and 4 treated (LS-T group) with supplemental IGF-I, and 30 healthy controls. METHODS: Ocular dimensions and refraction were measured, and a full ophthalmologic examination was performed. MAIN OUTCOME MEASURES: Differences in the average ocular dimension data among IGF-I-treated patients, untreated ones, and controls. RESULTS: The average axial length of eyes in the LS group was 21.94 mm (standard deviation [SD], 0.81). Corresponding values for the LS-T and control group eyes were 22.53 mm (SD, 1.74) and 23.20 mm (SD, 1.35) respectively. The average anterior chamber depth of eyes in the LS group was 2.55 mm (SD, 0.26). Corresponding values for eyes in the LS-T and control groups were 3.48 mm (SD, 0.09) and 3.84 mm (SD, 0.16) respectively. The average lens thickness of eyes in the LS group was 4.56 mm (SD, 0.36). Corresponding values for the LS-T and control groups were 3.77 mm (SD, 0.23) and 3.51 mm (SD, 0.25), respectively. The average corneal curvature of eyes in the LS group was 46.9 diopters (D) (SD, 2.32). Corresponding values for the LS-T and control groups were 47.6 D (SD, 2.83) and 44.4 D (SD, 1.5), respectively. CONCLUSIONS: Insulinlike growth factor I seems to be an important regulator of ocular growth as documented in patients with primary growth hormone insensitivity. The mechanism of this observation should be investigated further.

Estimation of prevalence and incidence rates and causes of blindness in Israel, 1998-2003.

BACKGROUND: The prevalence and incidence of blindness in Israel appear to be comparable to other western countries. Comparisons are difficult because of different definitions of blindness, and the uniqueness of the Israeli Registry of the Blind. OBJECTIVE: To characterize the population who were registered as Blind in Israel in the years 1998-2003 and estimate the prevalence and incidence of blindness by age and causes of blindness. METHODS: A retrospective review of the annual report of the national Registry of the Blind in Israel between 1998 and 2003 identified 21,585 blind persons who received a certificate for blindness. Blind persons are identified by ophthalmologists throughout Israel and referred to the Registry of the Blind if they have a visual acuity of 3/60 or worse, or a visual field loss of <20 degrees in their better eye. This report includes prevalence data on 21,585 persons enrolled in this review still alive and living in Israel in 2003. We estimated the prevalence rate of blindness nationwide and the incidence rate for each cause of blindness for every year. RESULTS: The main leading causes of blindness in Israel in 1998 were (in percent of the total number of newly registered patients): age-related macular degeneration (20.1%), glaucoma (13.8%), myopic maculopathy (12%), cataract (10.4%), diabetic retinopathy and maculopathy (10.1%), and optic atrophy (7.9%), and in 2003, 28%, 11.8%, 7.4%, 6.5%, 14.4% and 6.5% respectively. CONCLUSIONS: The results indicate that the incidence of age-related macular degeneration, diabetic retinopathy and maculopathy in Israel is increasing, while that of glaucoma, myopic maculopthy, optic atrophy and cataract is decreasing.

Ocular growth in premature infants conceived by in vitro fertilization versus natural conception.

PURPOSE: To evaluate the possible effect of in vitro fertilization (IVF) on early development of the eye in premature infants. METHODS: Biometric and keratometric values, intraocular pressure, and retinal vascular status were assessed in a cohort of 133 premature infants. These values were compared between premature infants conceived by IVF or naturally, and the relationship between these parameters and postconceptional age and weight at examination were evaluated. RESULTS: The sample consisted of 133 premature infants, 62 (46.6%) born by IVF and 71 (53.4%) by natural conception. Postconceptional age at examination was 28 to 46 weeks. In both groups, axial length, anterior chamber depth, and corneal radius correlated with the postconceptional age and weight at examination and followed a linear growth pattern. Lens thickness changed very slightly. The rate of retinal vascularization correlated with the postconceptional age as well. No correlation was found between intraocular pressure and corrected age or weight at examination. There was no difference between the study and control groups in any of the biometric or keratometric parameters or in intraocular pressure, according to two-way analysis of variance. CONCLUSIONS: IVF apparently does not affect early ocular growth, intraocular pressure, changes in corneal curvature, or retinal vascularization in premature infants. These findings may aid ophthalmologists in assessing ocular dimensions in this patient population.

Combined rectus muscle transposition with posterior fixation sutures for the treatment of double-elevator palsy.

PURPOSE: To evaluate the surgical and functional results of full horizontal tendon rectus muscle transposition to the superior rectus (SR) insertion, augmented by posterior fixation sutures, in patients with double-elevator palsy (DEP). DESIGN: Retrospective nonconcurrent interventional comparative case series. PARTICIPANTS: Fourteen consecutive patients with DEP. INTERVENTION: Six patients treated for DEP by vertical transposition of the horizontal muscles to the SR insertion (Knapp procedure) were compared with 8 patients treated by the Knapp procedure combined with fixation of the transposed muscles to the sclera, adjacent to the SR, with nonabsorbable sutures. MAIN OUTCOME MEASURES: Postoperative ocular alignment, ductions, binocular functions, and rate of reoperation. RESULTS: Ocular deviation: Mean distance and near deviations decreased by 84% and 83%, respectively (P = 0.012), in the augmented-surgery group versus 48% and 47%, respectively (P = 0.03), in the standard-surgery group. Duction: Mean elevation deficiency in abduction and adduction improved by 64% and 65%, respectively (P = 0.01), in the augmented surgery group versus 42% and 55% (P = 0.02) in the standard group. Binocular functions: 3 patients (37%), all in the study group, gained binocular function. Reoperation was required in 5 patients (83.3%) in the control group. The difference in postoperative improvement between the groups was statistically significant for all 4 parameters. No postoperative complications or duction anomalies were observed during the follow-up period of 15.4 months (standard deviation, 5.5). CONCLUSIONS: The augmented Knapp procedure with superior posterior fixation suture is the preferred surgical treatment for patients with DEP. Its use in this series avoided the need for multiple surgeries on other extraocular muscles.

Full vertical rectus muscle transposition combined with medial posterior fixation sutures for patients with adduction deficiency.

PURPOSE: To compare the surgical and functional results of full tendon rectus muscle transposition to the medial rectus muscle augmented with posterior medial fixation sutures in patients with adduction deficiency (ADD) and Duane's syndrome type 2. DESIGN: Retrospective nonconcurrent interventional comparative case series. PARTICIPANTS: Twelve consecutive patients with ADD and Duane's syndrome type 2. INTERVENTIONS: Six patients treated by the full tendon rectus muscle transposition procedure alone were compared with 6 patients treated by the full tendon rectus muscle transposition combined with posterior medial fixation sutures. MAIN OUTCOME MEASURES: Postoperative ocular alignment, duction improvement, binocular functions, and reoperation. RESULTS: In the augmented surgery group, mean distance and near deviation decreased by 74.5% and 74%, respectively, versus 56% and 59%, respectively, in the control group (P = 0.007 and 0.02, between-group comparison for distance and near deviation, respectively). Mean duction improved in 73% of the study group compared with 52% of controls (P = 0.025). No postoperative complications or duction anomalies were observed during follow-up in the entire cohort; reoperation was needed in 1 patient in the study group and in all 6 patients in the control group. CONCLUSIONS: The augmented full vertical rectus muscle procedure is a beneficial surgical approach for patients with ADD and Duane's retraction syndrome type 2, reducing the need for multiple extraocular muscle surgery.

Ocular injury in children from exploding microwaved eggs.

PURPOSE: To report an ocular injury caused by exploding microwave-cooked eggs. DESIGN: Case reports. METHODS: Two children exposed to exploding microwaved eggs were examined for facial burns and ocular trauma. RESULTS: One patient sustained mild corneal epithelial damage in both eyes and eyelid burn, which were treated conservatively. The other, injured in the same event, had symblepharon and moderate keratopathy requiring intensive lysis. CONCLUSIONS: Physicians should be alerted to the potential risk of vision-threatening ocular injury from exploding microwaved foods, and the public should be educated not to cook eggs in microwave ovens.

Clinical course and outcome of uveitis in children.

PURPOSE: We sought to evaluate the clinical course, complications, and visual outcome of pediatric uveitis. METHODS: Our sample included 38 consecutive children with uveitis treated between 1986 and 2002: 15 with idiopathic uveitis, 10 with Behcet disease, 9 with juvenile rheumatoid arthritis, 4 with other diagnoses. The last group was excluded from the analysis because of its small size. Appropriate ophthalmologic and laboratory examinations were obtained. Treatment consisted of topical, periocular, or systemic steroids with or without immunosuppression. RESULTS: Complications occurred in all 3 groups, although they tended to be more severe in the patients with juvenile rheumatoid arthritis. Visual acuity improved from presentation to final examination; the difference was statistically significant for the patients with idiopathic uveitis (P < 0.0005) and Behcet disease (P = 0.004). CONCLUSIONS: These findings support an intensive treatment approach to childhood uveitis. The visual prognosis is good even in patients with a severe clinical course.

Ultrasonographic demonstration of the superior ophthalmic vein in the orbit of premature infants with and without retinopathy of prematurity.

Retinopathy of prematurity (ROP), which develops due to abnormal retinal vascularization in premature babies, can lead to irreversible vision loss. B-scan ocular ultrasonography is a noninvasive examination which makes it possible to image the eye and orbit. Our purpose was to echographically assess the orbit of premature babies with and without retinopathy of prematurity (ROP), with a focus on the superior ophthalmic vein (SOV) which is normally not detected by orbital ultrasound. A prospective study design was used after approved by the local institutional review board. ROP was diagnosed by routine ophthalmoscopic exam. Orbital ultrasound was performed by a single experienced ophthalmologist and ultra-sonographer who was masked to the routine ROP screening results. The results of the ophthalmoscopic exam were compared to the orbital ultrasound findings. The study group was divided into those diagnosed with ROP and those not diagnosed with ROP and were found to be comparable by age and weight at the time of the US examination. The SOV was dilated in 21 of 22 eyes (95.4%) with ROP and in only 5 of 32 eyes (15.6%) without ROP. The present study suggests an association between ROP and dilatation of the SOV.

Swedish interactive thresholding algorithm fast for following visual fields in prepubertal idiopathic intracranial hypertension.

OBJECTIVE: To examine the reliability of Swedish Interactive Thresholding Algorithm Fast (SITA Fast) visual fields (VFs) in prepubertal idiopathic intracranial hypertension (IIH) and to compare whether age, gender, or severity of visual outcome influenced the reliability of VF tests. DESIGN: Prospective, longitudinal cohort study. PARTICIPANTS: Twenty-six prepubertal children (<11 years of age; mean age, 7.2 years) with IIH. TESTING: Children were prospectively followed up using a child-oriented program, which included SITA Fast VF tests. Age, gender, and severity of visual outcome were correlated with reliability of performance on SITA Fast VFs using a 1-way analysis of variance, point-biserial correlation, and the chi-square test for independence of observation. MAIN OUTCOME MEASURES: Statistical analyses results that correlated the reliability of SITA Fast VFs with age, gender, and visual outcome. RESULTS: Three children were treated at the age of 2 years and were unable to perform automated VF tests. Four children were treated at the age of 4 years, 3 of whom were able to perform repeatable reliable SITA Fast VF tests. Forty-two eyes of 21 children had an average SITA Fast test time of 4.5 minutes for each eye, compared with 8 minutes using the Fastpac strategy. Age was not associated with reliability scores of SITA Fast tests (F = 0.971, not significant [ns]). Gender did not influence the reliability of SITA Fast VF tests (chi-square((1)) = 0.669, ns), nor did severity of visual outcome (chi-square((2)) = 3.348, ns). Visual deficits were observed in 55% of patients at presentation and in 27% of patients after resolution of papilledema. CONCLUSIONS: The SITA Fast VF tests can be performed from age 4 years and offer a reliable method for shortening test time. A child-oriented follow-up program, which entails a shortened testing time, may improve outcome in prepubertal IIH.
