Do infants with isolated congenital sixth nerve palsy require comprehensive work-up? A retrospective cohort and review of the literature.

PURPOSE: The purpose of this study is to describe a case series of infants with isolated congenital sixth nerve palsy (ICSNP) and suggest a management algorithm based on our experience and a review of the literature. METHODS: A retrospective cohort design was used. The clinical database of a single tertiary medical center was reviewed to identify all patients diagnosed with ICSNP from January 2020 to November 2022. Data were collected as follows: demographic parameters, age at initial presentation, presenting symptoms and signs, findings on ophthalmic and neurologic examinations, findings on follow-up, and outcome. RESULTS: Six patients were included. All were born at term. The average gestational weight was 3675.7 ± 262.7 g. Three mothers had gestational diabetes. Five deliveries necessitated labor induction either by oxytocin (n = 4) or by membrane stripping followed by oxytocin (n = 1). One had also gone a forceps assisted delivery. Symptoms were noticed in all newborns by their parents within the first week of life. Ophthalmological and neurological examinations were otherwise unremarkable apart of one patient with a head turn to the side of the involved eye. Four patients underwent brain imaging that were unremarkable. All abduction deficits resolved by 1 to 3 months of age. Follow up examinations were unremarkable (mean follow up 14.3 ± 5.0 months, range 4-23). CONCLUSIONS: This case series, together with previous reports, support ICSNP's benign nature. We suggest an initial basic work-up that solely includes ophthalmological and neurological examinations which will be elaborated in case of any additional pathologic findings or if ICSNP does not fully resolve by 3 months.

Incidental Unilateral Macular Lesions in Children.

BACKGROUND: This study aims to examine the rare entity of unilateral macular lesions in the pediatric population and describe the distinct diagnoses and characterizations related to these findings. METHODS: A retrospective cohort design. The database of the ophthalmology clinic in a tertiary medical center was reviewed to identify all children with incidental unilateral macular findings, examined during 2016 through 2021. RESULTS: Twenty children were included. Mean age was 7.8 ± 3.4 years, 50% were girls. The most common macular lesion was torpedo maculopathy (50%), followed by pigmentary changes (25%), discoid maculopathy (15%), macular scar and combined hamartoma of the retina and retinal pigment epithelium (RPE) (5% each). None of the lesions changed after a mean follow-up duration of 2.3 ± 1.5 years. Visual acuity in the involved eye was equal to that in the contralateral eye in 90% of patients and did not change from initial to final visit. CONCLUSION: Incidental unilateral macular lesions in the pediatric population are usually benign, stable, and do not affect vision. Long-term follow-up is advised, as vision-threatening alterations may appear. [Ophthalmic Surg Lasers Imaging Retina 2023;54:346-352.].

Predictors for surgical intervention in orbital complications of pediatric rhinosinusitis.

OBJECTIVES: Orbital complications are the most common complication of acute rhinosinusitis, especially among pediatric patients. While most cases are treated with antibiotics alone, severe presentation may demand surgical intervention. Our goal was to determine which factors predict the need for surgery and to investigate the role of computerized tomography in the decision process. METHODS: A retrospective review of all children hospitalized between 2001-2018 with orbital complications of acute rhinosinusitis in a university-affiliated children's hospital. RESULTS: A total of 156 children were included. Mean age was 7.9 years (1-18 years). Twenty-three children (14.7%) were surgically treated, and the rest were conservatively treated. High fever, ophthalmoplegia and diplopia in association with minimal or no response to conservative treatment were predictive for surgical intervention, as well as higher inflammatory indices. Eighty-nine children (57%) underwent imaging during hospitalization. Presence of a subperiosteal abscess, as well as its size and its location were not found to be predictors for surgery. CONCLUSION: Clinical and laboratory findings in association with minimal or no response to conservative treatment predict the need for surgical intervention in cases of orbital complications of acute rhinosinusitis. As Computerized Tomography scans can have long-term implications in the pediatric population, caution and patience should be practiced when deciding on the timing of imaging in this population. Thus, close clinical and laboratory monitoring should lead the decision-making process in these cases and imaging should be reserved for when the decision for surgery has been made.

Academic benchmark of highly influential ophthalmologists listed in the ophthalmology power list.

OBJECTIVE: To review the academic benchmark of highly influential ophthalmologists listed in the ophthalmology '2020 Power List'. METHODS: In this cross-sectional study, the academic profiles, achievements, and bibliometric profiles of all ophthalmologists listed in the 'Power List of 2020', regarded as the most influential figures in ophthalmology today, were analysed. RESULTS: Ninety-five ophthalmologists were studied, after excluding 10 non-ophthalmologist figures that are also listed. Their mean age is 63 ± 11.7 years, with a strong male predominance (84.2%, n = 80 males, P < 0.001). All have a medical doctorate degree, and 31% (n = 29) have a Philosophy Doctor (PhD) degree. Fifty-three percent (n = 51) are graduates of medical schools in the United States (US). However, non-US ophthalmologists have a higher percentage of PhD degrees (41%, 18/44) vs. US ophthalmologists (22%, 11/51, P = 0.069), and also a longer duration of post-residency training (5.8 ± 3.1 vs. 1.8 ± 0.9 years, P < 0.001). The most common subspecialty was cataract and anterior segment surgery (42%, n = 40). The mean and standard deviation of the total number of papers published by ophthalmologists were 307.4 ± 226.3, with a mean citation record of 11,835.7 ± 13,330.5, and a mean h-index of 46.9 ± 27.9. CONCLUSIONS: The ophthalmologists listed on the 'Power List of 2020' are leaders with high accomplishments and an established interest in research evidenced by a high record of publications and an exceptional bibliometric profile. The list contains more US figures with a gender disparity, demonstrating a greater difficulty for international ophthalmologists, especially women, in achieving this high level of recognition.

A modified pediatric ocular trauma score for predicting visual outcome post open globe injury.

PURPOSE: To construct a new pediatric ocular trauma score for predicting visual outcome after open globe injuries (OGI) and to compare it to the ocular trauma score (OTS) and pediatric ocular trauma score (POTS). METHODS: This is a retrospective chart review study. For each case, the following data were collected: demographics, mechanism of the injury, initial ophthalmologic findings, presented and last follow-up visual acuity (VA), ocular treatments, and final ocular findings. We then analyzed the risk factors for the poor visual outcome (VA ≤ 20/200), and a modified pediatric ocular trauma score (MPOTS) was constructed accordingly and compared to the OTS and POTS for predicting poor outcome. Finally, a different cohort of pediatric OGIs was used for score validation. RESULTS: Forty-five cases were included, significant predicting factors for poor visual outcome were initial VA ≤ 20/200, zone 2-3 locations of injury, presence of retinal detachment, vitreous hemorrhage, hyphema, and iris prolapse at initial presentation. The calculated Spearman correlation coefficients between each system score and poor visual outcome were OTS 0.56, POTS 0.57, and MPOTS 0.64 (P < 0.001 for all). A total of 71 new cases were used as validation cohort, and calculated Spearman correlation coefficients between each system score and poor visual outcome were: OTS 0.50, POTS 0.51, and MPOTS 0.53 (P < 0.001 for all). CONCLUSIONS: We suggest a new scoring system for predicting poor final visual outcomes after OGI's in children, which is simpler and more clinically suitable for this study population. It was found to be a better predictor of visual outcome in this scenario compared with existing scoring systems.

Periodic Eye Examinations among Ophthalmologists: Attitudes, Performance, and Barriers for Compliance.

BACKGROUND: Preventive eye care is a preferred practice that includes recommended regular eye examinations, which is not always followed. OBJECTIVE: This study examined attitudes of ophthalmologists toward routine eye examinations, analyzed compliance with their own eye examinations, and described reasons for non-compliance. METHODS: This was a cross-sectional study involving an online survey, sent to all members of the Israeli Ophthalmological Society (IOS) asking their personal opinions concerning routine eye care, self-performance of these tests, and reasons for non-compliance. RESULTS: A total of 243 responses were received (59% males, mean age 52 years) representing 40% of IOS members. 98% of respondents think that adults should be routinely screened for eye diseases, most commonly annually (52%) or every two years (36%); however, only 55% of ophthalmologists reported having themselves a routine eye check in the past 3 years, which is significantly lower than their spouse (68%, P = 0.003). Recommendations for routine eye examinations were always higher than their actual performance regardless of the responding ophthalmologists' gender, age or country of birth. Furthermore, female gender was found to be a negative predictor of having these examinations. Pupil dilation was performed in 38% of ophthalmologists' testing, even though 80% of them think it is necessary for a complete examination. 'Lack of time' (35%) and 'forgetfulness' (31%) were the main reasons provided by ophthalmologists as an explanation for not having regular eye testing. CONCLUSIONS: Ophthalmologists typically recognize the importance of preventive eye care, recommending periodic eye examinations for their patients; however, self-performance of these evaluations by the ophthalmologists themselves is much lower.

Orbital Cellulitis in a Pediatric Population - Experience From a Tertiary Center.

OBJECTIVE: To describe our experience in treating children afflicted with orbital cellulitis. METHODS: A retrospective analysis of hospital records of children afflicted with orbital cellulitis was conducted between 2005-2018. Clinical, laboratory and radiology characteristics as well as management, microbiological data, and outcomes were collected. RESULTS: Of the 94 patients, painful restriction of ocular motility was observed in 37.2% and proptosis in 34%, whereas, only 18% of the children presented with both classical signs. Children aged older than 9 years presented with markedly elevated inflammatory markers i.e., leukocytosis and C-reactive protein (CRP). Only a minority (12, 12.4%) required functional endoscopic sinus surgery. CONCLUSION: Our data support the general approach that orbital cellulitis should be initially managed conservatively with close monitoring; since, only a minority of patients require surgical intervention.

Elevated intraocular pressure in children with acute lymphoblastic leukaemia: A prospective study.

Most childhood acute lymphoblastic leukaemia (ALL) protocols include high-dose steroid therapy. However, the known potential of high-dose steroids to significantly elevate intraocular pressure (IOP) and lead to glaucomatous optic neuropathy has not been intensively investigated in children with ALL. Moreover, as children with ALL do not routinely undergo IOP measurements, the need for IOP monitoring and therapy is unknown. We prospectively measured IOP in 90 children with newly diagnosed ALL attending a tertiary paediatric haematology/oncology centre, at diagnosis and at the middle and end of induction therapy. Ocular hypertension (IOP > 21 mm Hg) at any time point was documented in 64 children (71%), and the prevalence increased during induction. Thirty-six children (40%) had elevated IOP at ALL diagnosis before therapy initiation, and stratification to non-standard ALL was a risk factor. IOP reduction therapy was administered to 13 children (14%); none required surgery. Values normalised in all cases. On multivariate logistic regression analysis, dexamethasone therapy was a significant risk factor for ocular hypertension. High body mass index was an additional risk factor in children with elevated IOP at ALL diagnosis. Routine evaluation of IOP during steroid therapy is very important in children with ALL to ensure early intervention which may prevent permanent ocular damage.

Ophthalmologists and WhatsApp: Teleophthalmology is already here.

PURPOSE: To estimate the extent of WhatsApp utilization using text and media messages for inter-physician consultations among ophthalmologists (residents and specialists) at various clinical settings and its perceived benefits for ophthalmologists and their patients. We also aimed to detect obstacles that concern ophthalmologists when using WhatsApp as a consultation platform. METHODS: This was a cross-sectional study using a self-administered survey through Google Forms, which was sent to 660 practicing ophthalmologists during April to May 2020. RESULTS: One hundred and ninety-two ophthalmologists completed the questionnaire, 151 of which (78.6%) were specialists and 41 (21.4%) were residents. Most ophthalmologists reported using WhatsApp at least once a day for both personal and professional use. Residents reported lower rates of contacting patients using WhatsApp than specialists (1.51 ± 0.98 vs 2.72 ± 1.32, p < 0.001). Respondents reported WhatsApp consultations frequently replaced referrals of patients to other physicians, with a median of once a week. 97.8% of residents and 91.4% of specialists reported the ability to share media is a major advantage of WhatsApp over other medias, followed by rapid responses for consultations. CONCLUSION: Many ophthalmologists already use WhatsApp as a tool for professional consultations with other providers, mainly thanks to its simplicity and wide availability. Residents use it more frequently than specialists, and ranked it higher when asked how much WhatsApp has improved the clinical setting. Policy makers should address concerns brought up by physicians, such as documentation in medical records and proper compensation for consulting ophthalmologists during and after work hours.

Ocular Trauma Caused by Confetti Cannons.

BACKGROUND: Eye trauma is an unfortunate and often preventable cause of vision loss. Confetti cannons are common causes of injury. Awareness of ocular hazards of confetti cannons remains low because of limited reports describing ophthalmic injuries following their use. OBJECTIVES: To describe outcomes of ocular trauma caused by confetti cannons and to increase recognition of their ocular risks. METHODS: A retrospective analysis was conducted of eye injuries caused by confetti cannons presenting to a single medical center between 2016 and 2020. Data collected included age, gender, eye injured, ocular damage, visual outcome, and details of surgeries performed. RESULTS: Overall, six consecutive patients (2 males, mean age 19.5 ± 9.74 years) were identified and studied. In all patients only one eye was injured (3 right eyes) during a private celebration, most commonly (n=5) to a bystander while in the vicinity of a cannon operated by someone else. Most common eye injuries included corneal erosion (n=4), traumatic hyphema (n=4), and retinal edema (n=3). Mean initial logMAR visual acuity in the injured eye was 0.73 ± 0.18, improving to 0.25 ± 0.16 at the final visit (P = 0.125). Two patients underwent eye surgery due to their trauma: one to repair globe penetration and another to undergo intravitreal injection of tissue plasminogen activator and C3F8 for submacular hemorrhage, followed 8 months later by intravitreal bevacizumab injection for choroidal neovascularization. CONCLUSIONS: Confetti cannons pose hazards that can cause severe ocular trauma resulting in permanent vision loss. Increasing awareness of device hazards is necessary to prevent eye injuries.

External lumbar drainage in progressive pediatric idiopathic intracranial hypertension.

OBJECTIVE: Pediatric idiopathic intracranial hypertension (IIH) is characterized by increased intracranial pressure despite normal cerebrospinal fluid and neuroimaging findings. Initial management is typically medical; however, nearly 10% of children will eventually require surgery for persistent headache and/or vision loss. External lumbar drainage, which is a considerably safer treatment option, has not been adequately analyzed in children with medically refractory IIH. METHODS: The authors conducted a single-institution retrospective analysis of children with medically refractory IIH who had undergone external lumbar drain (ELD) placement because of worsening papilledema, reflected as increased retinal nerve fiber layer (RNFL) thickness on optical coherence tomography (OCT) testing. The main outcome measures were effects of external lumbar drainage on papilledema resolution, symptoms, and vision. RESULTS: The authors analyzed the medical records of 13 children with IIH (11 girls, mean age 15.0 ± 2.3 years) whose mean CSF opening pressure was 45.5 ± 6.8 cm H2O. In all children, the average global RNFL thickness in both eyes significantly increased at ELD placement (right eye 371.8 ± 150.2 µm, left eye 400.3 ± 96.9 µm) compared with presentation thickness (right eye 301.6 ± 110.40 µm, left eye 350.2 ± 107.7 µm) despite acetazolamide medical therapy (20-30 mg/kg/day), leading to ELD placement after 9.5 ± 6.9 days (range 3-29 days). After ELD insertion, there was headache resolution, gradual and continuous improvement in optic disc thickness, and preservation of good vision. CONCLUSIONS: ELD placement in children with medically refractory IIH who demonstrated worsening papilledema with increased RNFL thickening on OCT testing typically results in symptom relief and disc edema resolution with good visual outcome, often preventing the need for additional definitive surgeries that carry greater failure and morbidity risks.

Comparison of keratometry data using handheld and table-mounted instruments in healthy adults.

PURPOSE: To compare keratometry data between the handheld Retinomax K-plus 3 and the table-mounted IOLMaster 700. METHODS: Healthy adult volunteers were prospectively recruited to the study. All participants underwent 3 consecutive keratometry measurements using the Retinomax K-plus 3 and a single biometry assessment using the IOLMaster 700. Differences between the Retinomax K-plus 3 and the IOLMaster 700 were assessed using Wilcoxon test for paired samples, Spearman correlation, Bland-Altman and mountain plots. RESULT: Twenty-eight healthy subjects with a median age of 37 years (interquartile range (IQR) 28-44 years) were included in the study. The median mean keratometry (mean K) reading was higher using the Retinomax K-plus 3 (44.04D; IQR 42.96-45.61D) compared to the IOLMaster 700 (43.78D; IQR 43.22-44.90D, p < 0.01), with a mean difference of 0.18D (95% confidence interval (CI) 0.11-0.23D). Mean K readings were highly correlated between the 2 devices (r = 0.995, p < 0.01). Bland-Altman plots showed 95% limits of agreement between -0.14D and 0.49D. Frequency histogram of mean K reading differences between the Retinomax K-plus 3 and the IOLMaster 700 showed that 56% of cases were between ± 0.2D, 93% of cases were between ± 0.4D and all cases were between ± 0.5D. Mean corneal astigmatism measurement was higher using the Retinomax K-plus 3 (1.01 ± 0.40D) compared to the IOLMaster 700 (0.77 ± 0.36D), with a mean difference of 0.23 ± 0.37D (p < 0.01) between the devices. CONCLUSIONS: A good agreement exists between the Retinomax K-plus 3 and the IOLMaster 700 regarding keratometry readings. This enables cataract surgeons to safely use the Retinomax K-plus 3 device when indicated.

Incidence of non-glaucomatous ocular disease in patients with asymmetric optic disc cupping.

PURPOSE: To evaluate the incidence of non-glaucomatous ocular disease in patients with asymmetric optic disc cupping. METHODS: A retrospective case series, including consecutive patients with cup-to-disc ratio (CDR) asymmetry greater than 0.2. All patients underwent a complete neuro-ophthalmological examination, automated perimetry with the Humphrey 24-2 visual fields program. Retinal nerve fibre layer thickness was measured by optical coherence tomography (OCT). The results of neuroimaging, macular OCT and blood tests were recorded as well. Patients were assigned a diagnosis of glaucomatous optic neuropathy (GON) or non-glaucomatous disease (NGD). The main outcome measure was the rate of non-glaucomatous ocular disease. RESULTS: A total of 120 (67 males) patients with a mean age of 71.1 ± 12.5 years met the inclusion criteria and were included in this study. The mean asymmetry in CDR between the eyes was 0.3 ± 0.13 (range, 0.2-0.9). Twenty patients (16.6%) had a visual field defect not typical for glaucoma and positive relative afferent pupillary defect was found in 24 patients (20%). Six patients were found to have newly diagnosed non-glaucomatous ocular disease: maculopathy in three patients, retinopathy in one patient and traumatic optic neuropathy in two patients. Patients with NGD were significantly younger than the patients with GON (59.8 ± 23.3 vs. 71.3 ± 11.5 years, P = 0.001). Optic disc pallor was found in 4/93 patients with glaucoma compared to 3/6 with newly diagnosed non-glaucomatous disease (4.7% vs. 50.0%, P = 0.03). CONCLUSIONS: Asymmetric optic disc cupping can be associated with non-glaucomatous disease and may warrant neuro-ophthalmological evaluation, especially in younger patients or those with optic disc pallor.

Trametinib for orbital plexiform neurofibromas in young children with neurofibromatosis type 1.

INTRODUCTION: Plexiform neurofibromas (PNF) in neurofibromatosis type 1 (NF1) are usually diagnosed in childhood and can grow rapidly during this period. In 10% of patients, PNF involve the orbital-periorbital area and may cause visual problems including glaucoma, visual loss from amblyopia (deprivational, strabismic, or refractive), optic nerve compression, or keratopathy. Ptosis, proptosis, and facial disfigurement lead to social problems and decreased self-esteem. Complete surgical removal involves significant risks and mutilation, and regrowth after debulking is not uncommon. Inhibitors of the RAS/MAPK pathway have recently been investigated for their activity in PNF. We administered the oral MEK inhibitor trametinib to five young children with NF1 and PNF of the orbital area, with visual compromise and progressive tumor growth; and followed them clinically and by volumetric MRI. METHODS: Treatment was initiated at a mean age of 26.8 months (SD ± 12.8) and continued for a median 28 months (range 16-51). Doses were 0.025 mg/kg/day for children aged > 6 years and 0.032 mg/kg/day for those aged < 6 years. RESULTS: Volumetric MRI measurements showed a reduction of 2.9-33% at 1 year after treatment initiation, with maximal reductions of 44% and 49% in two patients, at 44 and 36 months, respectively. No change in visual function was recorded during treatment. One child reported decreased orbital pain after 2 weeks; and another, with involvement of the masseters, had increased ability to chew food. Toxicities were mostly to skin and nails, grades 1-2. CONCLUSIONS: Trametinib can decrease tumor size in some young children with orbital PNF and may prevent progressive disfigurement.

Neuroimaging in Children with Ophthalmological Complaints: A Review.

Pediatric patients are commonly referred to imaging following abnormal ophthalmological examinations. Common indications include papilledema, altered vision, strabismus, nystagmus, anisocoria, proptosis, coloboma, and leukocoria. Magnetic resonance imaging (MRI) of the brain and orbits (with or without contrast material administration) is typically the imaging modality of choice. However, a cranial CT scan is sometimes initially performed, particularly when MRI is not readily available. Familiarity with the various ophthalmological conditions may assist the radiologist in formulating differential diagnoses and proper MRI protocols afterward. Although MRI of the brain and orbits usually suffices, further refinements are sometimes warranted to enable suitable assessment and accurate diagnosis. For example, the assessment of children with sudden onset anisocoria associated with Horner syndrome will require imaging of the entire oculosympathetic pathway, including the brain, orbits, neck, and chest. Dedicated orbital scans should cover the area between the hard palate and approximately 1 cm above the orbits in the axial plane and extend from the lens to the midpons in the coronal plane. Fat-suppressed T2-weighted fast spin echo sequences should enable proper assessment of the globes, optic nerves, and perioptic subarachnoid spaces. Contrast material should be given judiciously, ideally according to clinical circumstances and precontrast scans. In this review, we discuss the major indications for imaging following abnormal ophthalmological examinations.

Academic background, professional experience, and research achievements of United States academic ophthalmology leadership.

PURPOSE: To characterize the academic background, professional experience, and scholarly achievements of United States (US) academic ophthalmologists serving in leadership positions. METHODS: This is a cross-sectional study. An online search of publicly available resources was conducted for demographics, background, research productivity, and academic appointments of academic ophthalmologists in leadership positions: chairperson (CP), vice chair (VC), service director (SD), and program director (PD). RESULTS: Five hundred and fifty-one academic ophthalmologists in leadership positions were analyzed. A male predominance was found in all positions, ranging from 86% male CPs to 68% of SDs. Eighty-nine percent were graduates of US medical schools, and 97% completed their residency in a US ophthalmology program. Harvard Medical School and The Johns Hopkins University School of Medicine and their affiliated programs were the most frequently attended by leaders. The most common subspecialties among leaders were surgical retina (21%), cornea (18%), and glaucoma (16%). Overall, 18% of leaders are endowed professors, 34% are full professors, 25% are associate professors, and 20% are assistant professors. Overall, 28% of department leaders were residents and 16% were fellows in their current program. Chairpersons, followed by their vice, are the most academically proficient leaders within their departments, having the largest number of publications and h, hc, hm, and AWCR bibliometric indices. CONCLUSIONS: Ophthalmology leaders in all positions are highly accomplished with an established interest in research. Typically, CPs and their VCs have a longer duration of professional experience with a greater research output and a superior median academic appointment. Gender discrepancies within leadership positions are evident.

Demographic, clinical features, and outcomes of pediatric non-penetrating ocular foreign bodies.

PURPOSE: Data regarding ocular foreign body (FB) in the pediatric population is sparse. The purpose of this study is to describe the demographic features and the outcomes of pediatric non-penetrating ocular FB. METHODS: The charts of all children with non-penetrating ocular FB who presented at a tertiary medical center between 2011 and 2018 were retrospectively reviewed. Data analyzed included demographics, ocular FB site, the need for general anesthesia, or sedation for FB removal and clinical outcomes. RESULTS: Three hundred and fifty-two children (58.8% boys) with a mean age of 7.7 ± 3.7 years were included. Two hundred and fifty-one (71.3%) children presented on the same day of injury. Patients with developmental delay presented more often with restlessness than patients without developmental delay (p < 0.0001). One hundred and forty-six (41.5%) of FBs were found on the conjunctiva, 128 (36.4%) under the eyelid, and 62 (17.6%) on the cornea. In 19 (4.5%) cases, general anesthesia or sedation was required for FB removal. A multivariate analysis identified young age (OR 0.976, 95% CI 0.961-0.992, p = 0.003), corneal FB (OR 50.84, 95% CI 10.08-256.37, p < 0.0001), and developmental delay (OR 18.56, 95% CI 1.22-283.45, p = 0.036), as significant predictors for the need of general anesthesia or sedation. Among patients with corneal FB, in two (3.2%) cases, the corneal FB was complicated by infectious keratitis, resulting in mild corneal scar. CONCLUSION: The rate of general anesthesia for non-penetrating ocular FB removal in children is low. Children presenting with non-penetrating ocular FB have good prognosis without long-term complications.

Ahmed Valve Tube Extension in Pediatric Glaucoma.

PRéCIS:: Ahmed valve tube extender showed good long-term outcomes for retracted tubes in pediatric glaucoma. The procedure is safe with limited complications. PURPOSE: To analyze the long-term outcomes of Ahmed valve tube extension in pediatric glaucoma patients. PATIENTS AND METHODS: This study analyzed the records of all children who underwent surgery involving extension of a pediatric Ahmed valve tube, treated at a tertiary medical center between 2007 and 2018. Surgical success was defined as intraocular pressure between 6 and 22 mm Hg and reduced by at least 20% from its preoperative value, with or without intraocular pressure lowering medications, without additional surgical procedures and without vision loss. RESULTS: Fourteen eyes of 11 children were treated with the Ahmed tube extender during the study period. Mean age of all children was 5.7±4.7 years (range, 3 mo to 16 y). The most common type of glaucoma was congenital glaucoma (n=6, 42.9%). The mean age at the time of initial valve implant was 2.39±3.89 years and the mean duration from initial insertion to the extension was 3.39±2.95 years. The mean follow-up was 72.8±43.3 months (range, 12 to 140 mo), with 85.7% followed for >2 years. The mean survival was 34.1±37.2 months after the extension. Three surgeries (21.4%) were primary failures, 8 patients (57.1%) failed during follow-up (mean, 40.6±44.4 mo after the extension; range, 1 to 125 mo), whereas 3 patients (21.4%) maintained the successful outcome until their last follow-up visit (mean, 37.7±24.1 mo; range, 12 to 70 mo). CONCLUSIONS: The Ahmed valve extender can often save a retracted or obstructed tube. The procedure has limited complications and long-term efficacy in one third of the patients.

When pediatric acute acquired comitant esotropia is not caused by a neurological disease.

BACKGROUND: Acute acquired comitant esotropia (AACE) is a relatively rare type of pediatric strabismus, often described as a possible presentation of intracranial pathology. The risk of having neurological disease in isolated AACE is not clear, because many previously published cases had other neurological or ophthalmological abnormalities. The purpose of this study was to analyze the incidence of neurological abnormalities in children presenting with AACE and otherwise normal neurological and ophthalmological evaluations. METHODS: The medical records of consecutive patients >4 years of age with AACE examined by a single practitioner from 2014 to 2018 were reviewed retrospectively. The main outcome measure was the presence of neurological disease. Children with duction deficits, incomitant esodeviations, and hyperopia of >2.00 D were excluded. RESULTS: A total of 20 children (11 males; mean age, 9.8 ± 4.1 years) were included. Mean esodeviation was 29.5Δ ± 14.8Δ (range, 10Δ-55Δ). All had an otherwise normal ophthalmological and neurological evaluations. Of the 20, 19 (95%) had normal brain neuroimaging. One child that did not have neuroimaging was followed over 2 years without developing any neurological sequelae. CONCLUSIONS: In our study cohort, pediatric AACE not accompanied by other ophthalmic and neurological abnormalities was not a manifestation of intracranial pathology. In such cases, the decision to perform neuroimaging should take into account other factors, including caregivers' preferences and availability for close monitoring.
