Lacrimal Obstruction in Craniosynostosis: Anatomical and Genetic Risk Factors.

PURPOSE: To investigate whether patients with craniosynostosis exhibit higher rates of nasolacrimal duct obstruction (NLDO) and to explore potential risk factors. METHODS: Retrospective review including all craniosynostosis patients treated at both the Divisions of Ophthalmology and Plastic, Reconstructive, and Oral Surgery at The Children's Hospital of Philadelphia between 2009 and 2020 was conducted. Synostosis characteristics, lacrimal disorders, and genetic data were collected. Main outcome measures were the rate of NLDO and associations with anatomical and syndromic/genetic risk factors. RESULTS: The total of 767 participants had a mean age of 2.8 ± 3.8 years, 465 (60.6%) were males, 485 (63.2%) had no syndromic association; 631 (82.3%) had one major suture involved, 128 (17%) had involvement of 2 to 4 major sutures, and 429 (55.9%) underwent craniofacial surgery. Forty-eight (6.2%) patients had NLDO, which more prevalent in the genetic/syndromic group (11.0% vs. 3.5%, respectively, p < 0.001), with the highest prevalence observed in patients with Apert syndrome (n = 4, 30.8%). The genetic variants most associated with NLDO were EFNB1 (n = 1, 100%) and FGFR2 (n = 6, 19.4%). There was no association between NLDO and the number or types of sutures involved or a history of craniofacial surgery. CONCLUSIONS: Nasolacrimal duct obstruction is more common in patients with craniosynostosis compared to the general population. Having a putative syndrome or a putative genetic variant and female sex were risk factors for NLDO. Ophthalmic evaluations for all craniosynostosis patients and careful assessments of any symptoms of tearing are recommended.

Outcome of Primary Monocanalicular Stent Placement in Pediatric Down Syndrome Patients with Congenital Nasolacrimal Obstruction.

PURPOSE: Congenital Nasolacrimal duct obstruction (CNLDO) is a relatively common problem in children with Down syndrome (DS). Probing and irrigation (PI) with monocanalicular stent intubation may be less successful than in non-DS patients, thus raising some concerns regarding the preferred treatment in this population. We aimed to analyze the surgical outcome of PI along with monocanalicular stent intubation in children with DS compared with non-DS patients. METHODS: Retrospective cohort study. Thirty-five eyes of 19 children with DS and 1,472 eyes of 1,001 children without DS underwent PI-monocanalicular stent intubation as a primary treatment for CNLDO. All patients were operated on by a single surgeon at the Children's Hospital of Philadelphia between 2009 and 2020. The main outcome measure was a surgical success, defined as the resolution of symptoms after surgery. RESULTS: A total of 1,020 patients were included, 48% females; mean age of 1.9 ± 1.4 years. The mean follow-up time was 35.0 months. The DS patients group consisted of 19 patients. Higher rates of right nasolacrimal duct obstruction and bilateral obstructions were observed in the DS group (100% vs. 73.2%; p = 0.006, and 84.2% vs. 46.8%; p = 0.001, respectively). Patients with DS had a lower success rate (57.1% vs. 92.4%; p < 0 .0001). The median time to failure was 3.1 months in the DS group, and 5.2 months in the group of patients without DS. The hazard ratio comparing DS to the no-DS outcome was 6.6 (95% CI: 3.2-13.7; p < 0.001). CONCLUSIONS: CNLDO in DS is more likely to be bilateral and less likely to resolve after primary monocanalicular stent placement.

Silicone sling frontalis suspension for congenital ptosis: Outcome of 174 consecutive cases.

BACKGROUND: Frontalis suspension (FS) is the treatment of choice in congenital ptosis with poor levator function. We report the surgical outcome of FS using a double triangle configuration of silicone slings in children. METHODS: A retrospective cohort study of all paediatric patients with simple myogenic congenital ptosis repaired with FS over a 12-year period (2009-2020). Each silicone sling was secured by simple knots. Pre- and post-operative margin reflex distance (MRD1 ) measurements were determined from clinical photographs using ImageJ Software. Main outcome measures were improvement in eyelid height, eyelid asymmetry, reoperation rate and timing. RESULTS: One hundred and thirty nine patients (174 eyes) were included, with 35 (25%) having bilateral surgery. Mean (±SD) age was 1.4 ± 1.9 years. Mean follow up time was 32 ± 20.5 months. Sixteen patients (11%) had a history of previous ptosis repair surgery. Mean MRD1 improved by an average of 1.5 mm. The final MRD1 in the group of patients who did not have a second procedure was a mean of 2.1 mm. The MRD1 difference between both eyes in all unilateral cases improved from 2.5 mm preoperatively to 1.2 mm at final visit (p < 0.001). In the 123 cases without a history of previous ptosis surgery, repeat ptosis repair was performed in 37 (30%) patients, 34.9 ± 19.9 months after the initial procedure. Overall, repeat repair was performed in 47 patients (34%). CONCLUSIONS: Double triangle silicone sling frontalis suspension has a favourable outcome in two-thirds of paediatric patients with simple myogenic congenital ptosis. Failed cases can be addressed with a second repair, using either autogenous fascia lata or a second silicone sling.

"Blepharophimosis-plus" syndromes: Frequency of systemic genetic disorders that also include blepharophimosis.

BACKGROUND: To determine the frequency of isolated blepharophimosis-ptosis-epicanthus inversus syndrome (BPES) versus systemic genetic disorders in patients presenting with blepharophimosis. METHODS: Retrospective clinical records review. The records of all patients with blepharophimosis seen in the Division of Ophthalmology at the Children's Hospital of Philadelphia during a 12-year-period (2009-2020) were reviewed for medical history, clinical examination findings and results of genetic analyses. RESULTS: The 135 patients identified with blepharophimosis included 72 females (53%) and 63 males (47%) whose mean ± standard deviation age at first visit was 3.5 ± 6.4 years (range 0-39.8 years). Sixty-seven of the patients (50%) had undergone genetic testing for FOXL2 gene mutation. Fifty-four (81%) harboured FOXL2 gene mutations and 13 (19%) did not. Altogether, 126 patients (93%) had a final diagnosis of isolated BPES. The remaining nine (7%) had syndromic diagnoses ("blepharophimosis-plus"), including Dubowitz syndrome (n = 2), Ohdo syndrome (n = 1), 22q11.2 duplication (n = 1) and 3q22 deletion (n = 2). Three patients with multiple congenital anomalies remain undiagnosed. CONCLUSIONS: Blepharophimosis is an eyelid feature occurring most commonly in isolation due to FOXL2 gene mutation, but can also be a harbinger of multisystem disease not exclusive to isolated BPES, as observed in 7% of cases in this series. The ophthalmologist is often the first to recognise these unique features, and must consider and rule out non-BPES syndromes before establishing a diagnosed classic BPES. A comprehensive genetic evaluation is, therefore, indicated in all cases.

Management of Pediatric Acute Dacryocystitis.

PURPOSE: To analyze the clinical presentation, course, and management in a large cohort of pediatric acute dacryocystitis subjects and to examine whether hospitalization and urgent surgical intervention are indeed mandatory. METHODS: A retrospective analysis of all pediatric subjects diagnosed with dacryocystitis at the Children's Hospital of Philadelphia over a 12-year period (2009-2020). RESULTS: One-hundred sixty-nine pediatric acute dacryocystitis patients were included in this study. Management included admission in 117 cases (69%). Sixty-eight patients (40%) were treated medically with no surgical intervention, 75 cases (44%) required urgent surgical intervention, and 26 additional cases (15%) required surgery due to persistent tearing symptoms after medical management. The urgent procedures included most commonly: 1) endonasal examination and microdebridement of intranasal cysts in 26 cases (35%); 2) probing and irrigation without examination and microdebridement, with or without stent intubation, in 30 cases (40%); and 3) dacryocystorhinostomy (13 endonasal and 4 external) in 17 cases (23%). CONCLUSIONS: Management of pediatric acute dacryocystitis should be tailored individually for each case. Hospital admission and early surgical intervention are not mandatory, as 31% of cases resolved without admission, and 56% without early surgical intervention. Although a specific age cutoff is not plausible, hospital admission for younger patients is more commonly advocated. When surgical intervention is indicated, endonasal examination and microdebridement of any associated intranasal cyst and probing with possible stenting are the initial procedures of choice. Dacryocystorhinostomy is reserved for more complex obstructions. Although pediatric acute dacryocystitis is an infection with serious potential problems, when managed appropriately, complications are rare.

Complex Stenoses and CT Features of the Nasolacrimal Canal in Congenital Nasolacrimal Duct Obstruction.

PURPOSE: To study the CT appearance of the nasolacrimal canal (NLC) in cases of congenital nasolacrimal duct obstruction (CNLDO) where there is a tactile sensation of a hard contact (HC) stop in the duct preventing stent intubation. METHODS: The authors retrospectively reviewed all consecutive cases of chronic CNLDO observed between 2003 and 2018 in which an apparent HC obstruction prevented nasolacrimal intubation. CT scans were reviewed to determine the cause of probing failure: distal stenosis, loss of parallelism of the NLC walls, abnormal angulations or an adjacent obstacle blocking tear outflow. RESULTS: Nine patients (12 sides) met the following criteria: CNLDO + HC + probing failure. The mean age at the time of the first HC was 3.9 years (range: 0.8-8.1 years) and at the time of a second confirmation of HC with subsequent dacryocystorhinostomy was 7.8 years (range: 4.1-9.2 years). Nasolacrimal duct opacification was noted in 33% of cases (4/12). Abnormalities of the NLC occurred in 8 of the 12 cases of CNLDO (8/12 = 66.6%) and on the asymptomatic side in 1 case (1/6 = 16.6%). A canine tooth bud situated in the same plane as the NLC was observed in 9 cases of CNLDO (9/12 = 75%) and on the asymptomatic side in 2 cases (2/6 = 33.3%). CONCLUSIONS: HC noted during probing is a sensitive but relatively nonspecific sign which, nevertheless, does indicate either a complex obstruction or at least potential intubation difficulties. As confirmed by CT imaging, a significant anatomical variant is not necessarily predictive of epiphora, but nevertheless may complicate the intubation procedure.The authors describe hard contact palpation during probing for CLNDO and its relationship to anatomic location and etiologies of obstruction in the nasolacrimal canal by CT imaging.

Simultaneous Versus Sequential Ptosis and Strabismus Surgery in Children.

PURPOSE: The authors sought to compare the clinical outcomes of simultaneous versus sequential ptosis and strabismus surgery in children. METHODS: Retrospective, single-center cohort study of children requiring both ptosis and strabismus surgery on the same eye. Simultaneous surgeries were performed during a single anesthetic event; sequential surgeries were performed at least 7 weeks apart. Outcomes were ptosis surgery success (margin reflex distance 1 ≥ 2 mm, good eyelid contour, and good eyelid crease); strabismus surgery success (ocular alignment within 10 prism diopters of orthophoria and/or improved head position); surgical complications; and reoperations. RESULTS: Fifty-six children were studied, 38 had simultaneous surgery and 18 sequential. Strabismus surgery was performed first in 38/38 simultaneous and 6/18 sequential cases. Mean age at first surgery was 64 months, with mean follow up 27 months. A total of 75% of children had congenital ptosis; 64% had comitant strabismus. A majority of ptosis surgeries were frontalis sling (59%) or Fasanella-Servat (30%) procedures. There were no significant differences between simultaneous and sequential groups with regards to surgical success rates, complications, or reoperations (all p > 0.28). CONCLUSIONS: In the first comparative study of simultaneous versus sequential ptosis and strabismus surgery, no advantage for sequential surgery was seen. Despite a theoretical risk of postoperative eyelid malposition or complications when surgeries were performed in a combined manner, the rate of such outcomes was not increased with simultaneous surgeries. Performing ptosis and strabismus surgery together appears to be clinically effective and safe, and reduces anesthesia exposure during childhood.

Orbital/Periorbital Plexiform Neurofibromas in Children with Neurofibromatosis Type 1: Multidisciplinary Recommendations for Care.

TOPIC: Children and adults with neurofibromatosis type 1 (NF1), a common autosomal dominant condition, manifest a variety of ophthalmologic conditions. Plexiform neurofibromas (PNs) involving the eyelid, orbit, periorbital, and facial structures (orbital-periorbital plexiform neurofibroma [OPPN]) can result in significant visual loss in children. Equally important, OPPNs can cause significant alteration in physical appearance secondary to proptosis, ptosis, and facial disfigurement, leading to social embarrassment and decreased self-esteem. CLINICAL RELEVANCE: Although NF1 is a relatively common disease in which routine ophthalmologic examinations are required, no formal recommendations for clinical care of children with OPPNs exist. Although medical and surgical interventions have been reported, there are no agreed-on criteria for when OPPNs require therapy and which treatment produces the best outcome. METHODS: Because a multidisciplinary team of specialists (oculofacial plastics, pediatric ophthalmology, neuro-ophthalmology, medical genetics, and neuro-oncology) direct management decisions, the absence of a uniform outcome measure that represents visual or aesthetic sequelae complicates the design of evidence-based studies and feasible clinical trials. RESULTS: In September 2013, a multidisciplinary task force, composed of pediatric practitioners from tertiary care centers experienced in caring for children with OPPN, was convened to address the lack of clinical care guidelines for children with OPPN. CONCLUSIONS: This consensus statement provides recommendations for ophthalmologic monitoring, outlines treatment indications and forthcoming biologic therapy, and discusses challenges to performing clinical trials in this complicated condition.

Childhood Optic Nerve Glioma: Vision Loss Due to Biopsy.

Two children without neurofibromatosis type 1 presented with unilateral decreased vision and MRI revealing optic nerve tumors. In the first case, chemotherapy was initiated empirically for presumed optic pathway glioma, but the lesion increased in size with associated clinical worsening, raising concern for a possible alternate diagnosis. Biopsy of the involved optic nerve resulted in worsening of vision due to a branch retinal artery occlusion and showed a grade I pilocytic astrocytoma. In the second case, sudden symptom onset and rapid tumor growth prompted an optic nerve biopsy, resulting in vision loss due to a central retinal artery occlusion and revealing grade I pilocytic astrocytoma. In both cases, tissue diagnosis did not alter the course of management. Instead, biopsy was associated with additional vision loss, highlighting the risk of biopsy in children with isolated optic nerve tumors and imaging that is most consistent with an optic pathway glioma.

Orbital and Periorbital Extension of Congenital Dacryocystoceles: Suggested Mechanism and Management.

Orbital and periorbital extension of congenital dacryocystoceles is rarely observed in neonatal infants. The authors describe 4 cases of congenital dacryocystocele that presented with extension to the orbital and periorbital regions. The first 3 newborns underwent marsupialization of the orbital and periorbital dacryocystoceles with aspiration of the purulent material followed by nasolacrimal duct probing after radiographic evidence of diffuse orbital or periorbital expansion. The fourth patient was successfully treated with an external dacryocystorhinostomy with excision of the enlarged cystic walls. Transconjunctival orbitotomy with sac marsupialization followed by nasolacrimal intubation can provide immediate and permanent resolutions of this unusual complication in most instances. External dacryocystorhinostomy may be required, however, when the orbital or periorbital dacryocystocele is complicated by acute or recurrent dacryocystitis.

Alveolar rhabdomyosarcoma masquerading as embryonal subtype: the value of modern molecular diagnostic testing.

A 3-year-old child presented with a history of conjunctivitis in her OS. She had hyperglobus of the OS and a palpable mass in the left inferior orbit. An urgent MRI revealed an enhancing mass in the left orbit. The patient underwent an incisional biopsy with pathologic assessment most consistent with embryonal rhabdomyosarcoma. However, subsequent molecular genetic testing of the biopsy specimen was positive for the PAX3/PAX7-FKHR chimeric gene, indicating the tumor was actually an alveolar rhabdomyosarcoma. The patient received a more intensive chemotherapy regimen and also was treated with proton-beam radiotherapy. After chemotherapy and proton irradiation, the patient's tumor shrank considerably, and she remained in remission at over 3 years of follow up. This patient illustrates the new tools at the disposal of the orbital specialist including molecular genetic testing and proton-beam irradiation to diagnose and treat orbital rhabdomyosarcoma.

Endoscopic dacryocystorhinostomy: the keys to surgical success.

PURPOSE: To describe a surgical technique for endoscopic endonasal dacryocystorhinostomy. METHODS: A consecutive case series of adult endoscopic dacryocystorhinostomy surgery was reviewed. The specific surgical approach of uncinectomy with or without septoplasty and anterior middle turbinectomy was noted. Postoperative follow up including endoscopic examination and results were documented. RESULTS: A total of 300 cases were included (271 patients) with average age of 66 (range 24-94). An uncinectomy was performed in 285 of 300 (95%) cases, a septoplasty in 82 of 300 (27%) cases and an anterior middle turbinectomy performed in 225 of 300 (75%) cases. Postoperative bleeding that required nasal packing occurred in 2 of 300 (0.6%) cases. Persistent nasolacrimal symptoms after surgery occurred in 18 of 300 (6.0%) cases with an average follow up of 28 months (range 1-70). Postoperative nasolacrimal symptoms were attributed to a persistent lacrimal sac (sump syndrome) in 1 of 300 (0.3%) cases, a mucocele recurrence in 2 of 300 (0.6%) cases, and scarring at the rhinostomy in 15 of 300 (5.0%) cases. CONCLUSIONS: Endoscopic endonasal dacryocystorhinostomy is an effective treatment for nasolacrimal duct obstruction. An uncinectomy, septoplasty, and anterior middle turbinectomy contribute to the optimal clearance of the common canaliculus and ultimate surgical success.

Punctal Atresia As a Clinical Indicator of Systemic Genetic Anomalies.

BACKGROUND: Punctal atresia or agenesis (PA) is a rare congenital anomaly characterized by the absence or closure of the tear duct puncta, potentially linked to systemic genetic anomalies. The necessity of a genetic workup based solely on the presence of PA remains uncertain. This study investigates a cohort of PA patients, examining the prevalence and types of associated syndromes. METHODS: A retrospective medical records review of all patients diagnosed with PA at the Children's Hospital of Philadelphia between 2009-2023 was conducted, analyzing medical histories and genetic testing results. Primary outcomes included the prevalence of systemic syndromes, while secondary outcomes focused on the variety of associated syndromes. RESULTS: Forty-four patients were included, of which 31 were male (70%) with a mean ± SD age 3.3 ± 3.3 years. Overall, 87 puncta in the study cohort were affected, and 26 cases (59%) were bilateral. Systemic abnormalities or genetic syndromes were identified in 19 patients (43%), with the most common being Ectodermal Dysplasia and Down syndrome. Additional rare syndromes were demonstrated. No significant association was found between systemic abnormalities and gender, bilaterality, or the number of puncta involved. CONCLUSIONS: A high incidence of systemic syndromes (43%) was observed in the study cohort. In individuals with PA who also exhibit extraocular disease, systemic evaluation and genetic workup should be considered. Syndromic diagnoses identified in our cohort also include: Branchio-oto-renal syndrome, 22q11.2 deletion syndrome, 1q21.1 microdeletion syndrome, NF1, monosomy 4q and trisomy 6q, which represent novel associations. The lack of correlation between PA's phenotypic severity and systemic abnormalities highlights the need to obtain a comprehensive medical history and consider a systemic workup in PA patients.

Management of congenital nasolacrimal duct obstruction in down syndrome.

BACKGROUND: Congenital nasolacrimal duct obstruction (CNLDO) is common in Down Syndrome (DS), and more difficult to treat. Our purpose was to describe the management of CNLDO in paediatric patients with DS. METHODS: Retrospective cohort study. Medical chart review of all DS patients diagnosed with CNLDO at the Division of Ophthalmology at the Children's Hospital of Philadelphia during a 12-year period (2009-2020). Main outcome measures included: Surgical interventions, primary probing outcome, rate of dacryocystorhinostomy (DCR) and/or conjunctivodacryocystorhinostomy (CDCR), and overall success. RESULTS: 126 patients (236 eyes) were included, mean age of 1.8 ± 2.1 years (range 0.1-11.3 y), 110 (87%) had bilateral CNLDO. Mean follow-up time was 41 months. 84 patients (67%) underwent at least one surgical intervention; the mean number of surgical interventions in this group was 1.8 ± 1.4 per patient (range, 1-6). The most common primary intervention was probing (n = 74, 88%), mostly (n = 57, 68%) with monocanalicular silicone intubation. Probing with silicone intubation had a higher success rate compared to probing alone (P = 0.002). Twenty (24% of 84) patients underwent DCR/CDCR during the follow-up period. Complete resolution was achieved in 123 patients (98%). CONCLUSIONS: CNLDO in Down syndrome is associated with high rates of bilateral obstructions and with less favourable surgical outcomes. Many patients ultimately require a more robust surgical intervention such as DCR or CDCR. The use of monocanalicular stent in initial probing was associated with a higher success rate, and would appear to be appropriate in all CNLDO-DS cases.

Cryptophthalmos: associated syndromes and genetic disorders.

PURPOSE: Cryptophthalmos is a rare congenital condition caused by anomalous eyelid development where the eyelid folds do not develop or fail to separate. Cryptophthalmos can be unilateral or bilateral and can occur in isolation or as part of an underlying syndrome. We aim to identify genetic syndromes associated with cryptophthalmos to facilitate genetic diagnosis. METHODS: We performed a retrospective medical record review of all patients diagnosed with cryptophthalmos followed at a single center between 2000 and 2020. The analysis included medical history, clinical examination findings, and genetic testing results. RESULTS: Thirteen patients were included, 10 (77%) males, mean age of 2.4 years. Eight (61%) had bilateral cryptophthalmos, and 4 (31%) had complete cryptophthalmos. Associated ocular abnormalities included corneal opacities (13/13, 100%), upper eyelid colobomas (12/13, 92%), and microphthalmia/clinical anophthalmia (3/13, 23%). All cases of complete cryptophthalmos had bilateral disease. An underlying clinical or molecular diagnosis was identified in 10/13 (77%) cases, including Fraser syndrome (n = 5), amniotic band syndrome (n = 1), FREM1-related disease (n = 1), Goldenhar versus Schimmelpenning syndrome (n = 1), MOTA syndrome (n = 1), and CELSR2-related disease (n = 1). CONCLUSION: This is the first report of a possible association between cryptophthalmos and biallelic CELSR2 variants. Children with cryptophthalmos, especially those with extra-ocular involvement, should be referred for comprehensive genetic evaluation.

The surgical management and outcomes of kissing nevi of the eyelids.

PURPOSE: To describe the clinical characteristics, surgical technique, and outcomes in patients with kissing nevi who underwent surgical management in two tertiary referral centers. METHODS: Medical chart review was conducted for all patients who underwent surgical repair in Moorfields Eye Hospital and The Children's Hospital of Philadelphia. Demographics, medical history, lesion characteristics, surgical intervention, and outcomes were collected. Main outcome measures were surgical interventions as well as functional and cosmetic outcomes. RESULTS: Thirteen patients were included. Mean age at presentation was 23.46 years (±19.35,4-61), and the mean number of surgeries per patients was 1.9 (±1.3,1-5). Initial procedure included incisional biopsy in three cases (23%) and complete excision and reconstruction in 10 cases (77%). Surgery involved the upper and lower anterior lamella in all cases, the upper posterior lamella in 4 patients (31%), and the lower posterior lamella in 2 patients (15%). Local flaps were utilized in 3 cases and grafts in 5 cases. Complications included: trichiasis (n = 2, 15%), lower eyelid ectropion (n = 2, 15%), mild ptosis (n = 1, 8%), and upper/lower punctal ectropion (n = 1, 8%). Twelve patients (92%) were satisfied with the final functional and cosmetic outcome. No recurrence or malignant transformation were observed in any patient. CONCLUSION: The surgical management of kissing nevi can be challenging, and commonly includes the use of local flaps or grafts, often requiring multiple interventions. The approach should be based on lesion size and location, proximity and involvement of key anatomical landmarks, as well as individual facial characteristics. Surgical management has a favorable functional and cosmetic outcome in the majority of patients.

Outcome of silicone sling frontalis suspension in children with simple congenital and complex ptosis.

OBJECTIVE: To compare the outcome of silicone sling frontalis suspension (FS) surgery in children with simple congenital ptosis and children with complex ptosis. DESIGN: A retrospective cohort study. PARTICIPANTS: All pediatric patients who underwent silicone sling FS surgery between 2009 and 2020 at a single centre. METHODS: Patients were divided based on etiology into simple congenital ptosis and complex congenital ptosis. Pre- and postoperative margin-to-reflex distance (MRD1) measurements were determined from clinical photographs. Main outcome measures were assessed as differences in improvement in eyelid height and reoperation rate between the groups. RESULTS: Two-hundred and eight children were included: 139 simple and 69 complex cases, with 83 females (40%). Mean (±SD) age at intervention was 1.9 ± 2.9 years. Complex cases included blepharophimosis epicanthus inversus syndrome (n = 35), Marcus Gunn jaw-winking syndrome (n = 12), oculomotor palsy (n = 8), congenital fibrosis of extraocular muscles (n = 3), chronic progressive external ophthalmoplegia (n = 3), and others. Mean MRD1 improved by an average of 1.6 mm in both groups. Repeat ptosis correction was performed in 50 of 171 patients (29%) without a history of failed ptosis procedures, and this rate was similar between simple and complex cases. Children under 3 years of age had higher rates of repeat ptosis repair than older children (n = 59 of 175 [34%] vs n = 5 of 33 [15%]; p = 0.03, χ2 test). CONCLUSIONS: Silicone sling FS has a favourable outcome in 70% of pediatric patients. Preoperative and final MRD1 and reoperation rates were similar between both groups, suggesting that despite the higher complexity in atypical cases, the outcome is similar.

A controlled study of topical 0.25% timolol maleate gel for the treatment of cutaneous infantile capillary hemangiomas.

PURPOSE: To evaluate the efficacy of topical 0.25% timolol maleate gel for the treatment of cutaneous infantile capillary hemangiomas. METHODS: A retrospective, consecutive, nonrandomized, comparative single-masked cohort study of all patients presenting with nonvision-threatening periocular infantile capillary hemangiomas between August 2007 and January 2011 was performed. Parents chose twice daily topical 0.25% timolol maleate gel or observation. Photographs were taken at all visits and subsequently evaluated by masked examiners for change in lesion size, color, and thickness. Lesions were clinically defined as superficial, mixed, or deep. The primary outcome was response to treatment at 2 months, categorized as good (size decreased .50%), moderate (decrease 0-50%), or poor (enlarged or caused visually significant ptosis or induced astigmatism). The secondary outcome was response at latest follow-up visit. RESULTS: Thirteen children received timolol, and 10 children were observed, with mean ages at presentation of 4.8 and 3.7 months (p 5 0.31), respectively. In the treated group, good response was observed in 8 (61.5%) infants, moderate response was seen in 4 (30.8%), and poor response was seen in one patient (7.7%). In the observed group, 0 (0%) demonstrated good response, one (10%) demonstrated moderate response, and 9 demonstrated poor response (90%) (p , 0.001). Responses were consistent on long-term follow-up (range 3-41 months). Both superficial (n 5 5; 100% good response) and mixed (n 5 7; 43% good, 57% moderate) lesions responded well to timolol; the one deep lesion did not. No adverse ocular or systemic effects were observed. CONCLUSIONS: Topical timolol maleate gel 0.25% is effective in treatment of nonvision-threatening infantile capillary hemangiomas with a superficial component. Response at 2 months is stable over time.

Recovery of Vision after Optic Nerve Sheath Fenestration in Children and Adolescents with Elevated Intracranial Pressure.

PURPOSE: To evaluate the effect of optic nerve sheath fenestration (ONSF) on the recovery of visual function in pediatric patients with optic disc swelling owing to increased intracranial pressure. DESIGN: Retrospective case series. METHODS: Medical chart review of all pediatric patients who underwent ONSF between 2009 and 2020 at the Children's Hospital of Philadelphia. Visual function was assessed at pre and postoperative visits. The main outcome measures were visual acuity, color vision, extraocular motility, visual field mean deviation, retinal nerve fiber layer thickness measured by optical coherence tomography. RESULTS: Fourteen pediatric patients (10 females; mean ± SD age of 14 ± 2.6 years; range, 8.5-17.5 years) were included. Five patients underwent bilateral surgeries. Ten patients were diagnosed with idiopathic intracranial hypertension. Of the 10 idiopathic intracranial hypertension patients, 3 had a previous history of weight gain and 2 of systemic steroid treatment; these can be referred to as pseudotumor cerebri. The mean ± SD follow-up length was 16.4 ± 12.3 months. VA improved from 20/138 to 20/68 in the operated eye (P = .0003) and from 20/78 to 20/32 in the nonoperated eye (P = .02). Color vision improved in the operated eye (P = .04), extraocular motility improved in the operated and nonoperated eye (P = .002 and P = .04 respectively). Visual field mean deviation improved in the operated (-23.4 dB to -11.5 dB, P < .0001) and nonoperated eye (-19.8 dB to -6.8 dB, P = .02). Retinal nerve fiber layer thickness improved in the operated eye (349.1 to 66.2 µm; P < .0001). The postoperative improvement was observed as early as the postoperative day 1. CONCLUSIONS: ONSF produces a rapid and persistent vision improvement in both the operated eye and the nonoperated eye. In children and young adults with papilledema and elevated intracranial pressure causing vision loss that is severe at presentation or refractory to standard medical management, ONSF should be considered.
