Lower eyelid retraction repair using autologous auricular scapha cartilage.

PURPOSE: To assess the efficacy of lower eyelid retraction surgery utilizing autologous auricular scapha cartilage (located within the anterior surface groove between the helix and anti-helix) and to present the surgical outcomes in a patient cohort. METHODS: Medical records of 21 patients who underwent lower eyelid retraction surgery with scapha cartilage were retrospectively reviewed. Retractions, present for an extended duration (6 months to 20 years), exhibited 1 mm or more inferior scleral show, attributed to prior lower eyelid blepharoplasty, facial palsy, or as a normal anatomical variation. Surgical interventions included lateral canthotomy, cantholysis, incision of the subtarsal conjunctiva-lower eyelid retractors, lower eyelid retractor lysis, cartilage graft suturing to the defect area without conjunctival cover, and tightening of the lateral canthal corner in all patients. RESULTS: A total of 29 eyelids in 21 patients underwent surgery without intraoperative complications. Over a mean follow-up period of 11 months (range: 6-30 months), lower lid retraction improved in 96.5% of eyelids. Postoperative margin-to-reflex distance measurements (MRD2) significantly decreased compared to preoperative values (p = 0.001; p < 0.01). Average improvements in MRD2-a (midpupil to lower lid) and MRD2-b (lateral limbus to lower lid) were 1.77 ± 0.80 and 2.04 ± 0.81, respectively (p = 0.001; p < 0.01). Four eyelids (4/29) required revision due to canthal corner loosening, with correction necessitating periosteal flaps. All four patients had previously undergone two or more repairs elsewhere. The graft was visible in two lids but did not require further revision. One patient experienced mild helix deformity at the donor site, which did not warrant additional intervention. CONCLUSION: In cases of lower lid retraction associated with middle/posterior lamellar shortening, utilizing an autologous auricular scapha cartilage spacer graft offers notable benefits. These advantages comprise straightforward harvesting with minimal donor site complications, stability without experiencing shrinkage, a softer texture in comparison to posterior cartilage, a concave shape that facilitates proper fitting on the globe, and its autologous nature.

An Atypical Paediatric Optic Nerve Sheath Meningioma.

A 16-year-old male presented with a three year history of right proptosis. All other ocular findings were normal. Imaging demonstrated a large, calcified, contrast-enhancing mass in the apical orbit. The tumour had high gallium-68-DOTATATE uptake and low 18F-2-fluoro-2-deoxy-D-glucose uptake. An incisional biopsy revealed a diagnosis of psammomatous optic nerve sheath meningioma (ONSM). One year later stereotactic radiotherapy was performed due to tumour growth. Tumour size and visual acuity remained stable in the six months after treatment. This case differs from previously reported paediatric ONSMs by its histo-clinical characteristics (exophytic-calcified mass, visual preservation, psammomatous histology).

Horizontal Gaze Palsy with Progressive Scoliosis: A Case Report and Literature Review.

Horizontal gaze palsy with progressive scoliosis (HGPPS) is a rare autosomal recessive disorder. The ROBO 3 gene mutation is responsible for the disease. We present a boy aged 12 years who was admitted for scoliosis surgery who had also had horizontal gaze palsy since birth. His brainstem abnormalities were compatible with the syndrome of HGPPS. HGPPS is one of the rare congenital diseases of childhood. Horizontal gaze palsy, ametropia, and progressive scoliosis are the main findings of the disease. This syndrome should be kept in mind for both ophthalmologists and orthopaedic surgeons in patients who present with gaze palsy and scoliosis. Early diagnosis of scoliosis makes it possible to treat the disease at an early stage, and early diagnosis of ametropia is important in the prevention of amblyopia.

Mode of delivery, birth weight and the incidence of congenital nasolacrimal duct obstruction.

AIM: To study any possible association of congenital nasolacrimal duct obstruction (CNLDO) with mode of delivery, birth weight and gestational age. METHODS: We retrospectively reviewed charts of all patients (n=2591) under the age of 3y who were born between April 2015 and May 2017 and were examined at the Ophthalmology Clinic of Emsey Hospital Istanbul, Turkey. We identified patients (n=105) who were diagnosed as CNLDO. The mode of delivery, birth weight and gestational age along with any adverse event during or after delivery or any other health history were determined. Birth statistical data were obtained from the hospital's medical records database. RESULTS: Gestational age of babies who were born via cesarean section (CS) was lower than gestational age of babies who were born via normal spontaneous vaginal delivery (NSVD; P=0.002). Babies who were born via CS were found to have 3.75 times higher risk of developing NLDO when compared to babies who were born via NSVD (OR=3.754). CONCLUSION: There is a possible association between CS and CNLDO.

Sixth nerve palsy following botulinum toxin injection for facial rejuvenation.

BACKGROUND: Botulinum toxin A (BTX) has been widely used for a variety of facial esthetic procedures within the last couple of decades. Efficacy and safety of BTX for facial rejuvenation has been extensively studied in multiple randomized prospective controlled trials. Focal weakness is among the most commonly reported adverse effects. Adverse reactions tend to occur most commonly due to errors in dosing formulation and errors with the techniques of the application. No serious long-term complications have been reported. MAIN OBSERVATION: We present the case of a 52-year-old female presenting with diplopia one week following the injection of BTX for facial rejuvenation at glabella, forehead and crow's feet areas. CONCLUSIONS: Injection of BTX adjacent to periorbital area may be associated with extra-ocular muscle paralysis.

Intraorbital foreign bodies: Clinical features and outcomes of surgical removal.

BACKGROUND: The present study is an evaluation of clinical features and management outcomes of patients operated on for intraorbital foreign bodies (FBs). METHODS: Medical records of 24 patients who underwent surgery for intraorbital FBs within a 10-year period were reviewed. RESULTS: Twenty patients (83%) were male and 4 (17%) were female (mean age: 28 years; range: 4-69 years). Ten patients (42%) presented within 48 hours of injury, 7 (29%) within 3 days to 1 month, and 7 (29%) more than 1 month after injury. FBs were inorganic in 19 patients (79%), and organic in 5 (21%). Major ocular morbidities were orbital cellulitis (n=5), traumatic optic neuropathy (n=3), globe perforation (n=2), and rupture of rectus muscle (n=2). FBs could be completely removed in all cases. Mean follow-up time was 26 months (range: 1 month-10 years). CONCLUSION: Intraorbital FBs are usually inorganic and metallic, and occur more frequently in young males. Orbital cellulitis, considered typical for organic FBs, may also occur with metallic that perforate lacrimal sac or paranasal sinuses. With appropriate caution, intraorbital FBs can be removed safely with current orbitotomy techniques.
