limbal dermoid

BACKGROUND: To report a case of a 4-year-old patient with Goldenhar syndrome. CASE PRESENTATION: The author presents a rare case report involving a 4-year-old boy with multiple malformations. A comprehensive examination showed that the patient primarily had a limbal dermoid. He also has bilateral microtia and ear canal deformities. The skull CT scan and spine X-ray showed Maxillofacial Abnormalities and scoliosis. Whole Exome Sequencing revealed potential gene variations related to microtia...

The present study reports the case of a superficial limbal dermoid surgically treated without suture by using a new technique of lamellar keratoplasty with allogenic lenticule from small incision lenticule extraction. The limbal lesion area was circumscribed by a trephine marker and lamellae were peeled off the anterior corneal stroma and sclera. After excision of the dermoid, the liquid on the bed was dried as much as possible and an appropriate stromal lenticule was attached to the implant bed without fibrin glue or suture...

BACKGROUND: Paediatric conjunctival lesions are rare and diverse. Though often indolent and asymptomatic, they can in some cases be sight or life-threatening. Awareness of concerning features of conjunctival lesions is key to optimal management. We aim to provide insight into management of paediatric conjunctival lesions though a review of cases in our service in last 12 years. METHODS: We present a retrospective analysis of our population-based cohort of children with conjunctival lesions presenting to our regional service in Belfast between 2011 and 2022 inclusive...

PURPOSE/AIM: To report the birth prevalence and natural history of congenital corneal opacities among a population-based cohort of children. MATERIALS AND METHODS: The medical records of patients <5 years diagnosed with a congenital onset corneal opacity while residing in Olmsted County, Minnesota, from January 1, 1977, through December 31, 2016, were retrospectively reviewed. RESULTS: Fourteen patients were diagnosed with a congenital corneal opacity during the 40-year study period for a birth prevalence of 1 in 5188 live births...

Limbal dermoid is a congenital benign tumor of the limbus which is often managed by surgery if necessary. In dermoid lesions involving the deep stroma, tumor excision and reconstruction of the anterior segment with amniotic membrane transplantation or keratoplasty may be required. Herein, we present a case of deep limbal dermoid treated with surgical resection and lamellar keratoplasty using microkeratome-assisted anterior lamellar graft.

BACKGROUND: To report a long-term outcome of the novel combined surgical method of complete excision, corneal tattooing, and a sutureless limbal conjunctival autograft for limbal dermoid. METHODS: All patients who were referred to our clinic for limbal dermoid, and underwent a combined surgery of complete excision, corneal tattooing, and a sutureless limbal conjunctival autograft were retrospectively reviewed. The surgery was performed by one surgeon, and all clinical information was obtained during a seven-year follow up period...

AIM: To observe the clinical efficacy of the combined use of small incision lenticule extraction (SMILE)-derived lenticule patches in corneal dermoid excision, with fixation of the lenticule patches assisted by fibrin glue. METHODS: Seventeen eyes of 17 patients with corneal dermoid were treated with dermoid removal combined with SMILE-derived lenticule transplantation. All lenticule patches were fixed by fibrin glue. Ocular changes were assessed using slit lamp microscopy and anterior-segmental optical coherence tomography...

The transparency of the cornea is critical to its role in transmitting light. Loss of corneal transparency results in visual impairment. Corneal pigmentation results from melanin accumulation in the epithelial cells of the cornea. Differential diagnosis for corneal pigmentation include corneal sequestrum, corneal foreign body, limbal melanocytoma, iris prolapse, and dermoid. These conditions must be excluded to reach a diagnosis of corneal pigmentation. A myriad of ocular surface conditions are associated with corneal pigmentation, including qualitative and quantitative tear film deficiency, adnexal disease, corneal ulceration, and breed-related corneal pigmentation syndromes...

PURPOSE: Ocular surface lipodermoids with corneal involvement may require surgical intervention; if deep, ocular surface reconstruction with lamellar corneal tissue or amniotic membrane may be needed. We describe a staged technique using autologous ipsilateral simple limbal epithelial transplantation. METHODS: After verifying sparing of Descemet membrane, the conjunctival portion of the lipodermoid was debulked in the first stage. Six weeks later, the corneal portion was excised, followed by autologous ipsilateral simple limbal epithelial transplantation to promote rapid reepithelialization of the residual stromal bed...

PURPOSE: To find preoperative simple geometric parameters to predict the outcome of lamellar keratoscleroplasty in patients with corneal limbal dermoids. METHODS: We retrospectively analyzed the data of 30 patients with limbal dermoids who underwent lamellar keratoscleroplasty and were followed up for more than 6 months. Seven geometric parameters were used to analyze the relationship with postoperative visual acuity, astigmatism, and scar formation and investigated for their influence on postoperative outcome...

Goldenhar syndrome is a rare congenital disorder. Limbal dermoid associated with this syndrome can cause high astigmatism and amblyopia in children. We report significant reduction in astigmatism, after limbal dermoid excision with lamellar keratoplasty, in a rare case of Goldenhar syndrome. A three-year-old female patient, with left-sided limbal dermoid with high astigmatism and amblyopia, was referred to us for visual rehabilitation. The patient had left-sided limbal dermoid and preauricular appendages. Oral examination revealed bifid labial frenum, a deep antegonial notch on the left side of the mandible and missing left upper central incisor teeth...

We present a case of SCALP syndrome, which was diagnosed in a male infant with the characteristic findings of sebaceous nevi, central nervous system malformations, aplasia cutis congenita, limbal dermoid, and giant congenital melanocytic nevi, or pigmented nevi. We identified a germline compound heterozygous DOCK6 mutation and a somatic mosaic NRAS Q61R mutation in the giant congenital melanocytic nevus. This report will increase clinician awareness of SCALP syndrome and augment the literature in characterizing this rare syndrome, including its genetic background...

In this report we illustrate the ophthalmologic assessment of two patients affected by Proteus Syndrome (PS), an extremely rare genetic disorder. Case #1 describes a 26 year old male patient followed for multiple ophthalmic anomalies: a limbal dermoid cyst, a unilateral cataract, bilateral nystagmus, severe myopia and unilateral optic nerve head drusen. Case #2 describes a 20 year old female patient referred to our Ophthalmology Department for a routine ophthalmologic evaluation after being treated for 3 years with Miransertib (an experimental AKT-pathway inhibitor)...

We examined the refractive characteristics and related factors of amblyopia in pediatric patients with limbal dermoids undergoing lamellar keratoscleroplasty. Forty-one children (mean age: 56.15 ± 22.47 months) were enrolled. Cycloplegic refraction, corneal topography, and anterior segment photography were performed. The corneal topographic and distribution characteristics of the refractive state were summarized, and the relationship between limbal dermoid invasion size and the refractive state was analyzed...

PURPOSE: To evaluate the presenting complaints, surgical management, surgical outcomes, complications, and postoperative visual acuity following limbal dermoid excision. DESIGN: Retrospective cohort study. METHODS: Medical records of patients with limbal dermoid presenting between January 2012 and December 2020 were retrieved to extract data regarding demographics, presenting profiles including the best-corrected visual acuity (BCVA), symptoms, anterior segment examination, and refraction...

Proteus syndrome is a very rare disorder with progressive, asymmetrical, and disproportionate overgrowth of body parts with a highly variable phenotype. It is associated with mosaicism for the recurrent heterozygous somatic gain-of-function variant c.49G>A (p.Glu17Lys) in the protein kinase AKT1. We report on a girl with a progressive intraosseous lipoma of the frontal bone and additional, nonspecific features including mild developmental delay, strabism, and a limbal dermoid of the left eye. She did not fulfill the criteria for a clinical diagnosis of Proteus syndrome...

Limbal dermoid (LD) is a congenital ocular tumor that causes amblyopia and damages visual acuity (VA) and visual function. This study evaluated the therapeutic efficacy of perceptual learning (PL) toward improving contrast sensitivity function (CSF) and VA. A total of 25 children with LD and 25 normal children were compared in terms of CSF and VA. The LD group was further randomly allocated into two arms: nine underwent PL combined with patching and eight underwent patching only; eight patients quit the amblyopia treatment...

This is a case series study that reported the management outcomes of five cases of limbal dermoid that were managed during infancy and childhood. Oculoauriculovertebral dysplasia or Goldenhar syndrome was present in one of the infants treated. Limbal dermoid, preauricular skin appendages, Duane's disease, tetralogy of Fallot, and sacral agenesis were all present. The limbal dermoid was the only finding in the other patients. Although some limbal dermoid didn't affect the vision, others can affect the vision by inducing astigmatism leading to amblyopia in children...
