ABSTRACT
Purpose@#To evaluate the results of the frontalis sling operation using a silicone rod for the correction of ptosis in patients with third nerve palsy with a focus on corneal safety. @*Methods@#Patients with third nerve palsy who underwent the frontalis sling operation using a silicone rod between 2008 and 2019 were included in this study. The medical records of all patients were reviewed, and their clinical characteristics and postoperative outcomes were analyzed. In this retrospective, interventional case series, the main outcome measures were eyelid contour, eyelid height by margin reflex distance, and corneal status. @*Results@#Twenty-four eyes of 18 patients (12 male and six female patients) were included. The mean age at the time of surgery was 35.1 years (range, 5–64 years). Twelve patients underwent a unilateral ptosis operation, and six patients received a bilateral ptosis operation. The mean follow-up period was 32.1 months (range, 2–87 months). Most patients (21 of 24 eyes, 88%) showed poor Bell’s phenomenon on preoperative examination. Satisfactory eyelid height and eyelid contour were achieved in almost all patients (mean postoperative margin reflex distance, +1.2 mm) postoperatively. Although corneal erosions were detected for several months in eight of 24 eyes after surgery, these findings were well controlled medically with artificial tear eye drops and ointments. @*Conclusions@#Frontalis sling surgery using a silicone rod can safely and effectively correct ptosis without severe corneal complications in patients with third nerve palsy. Our study outlines a new method to define the postoperative safety outcome by specifically focusing on categorized corneal status.
ABSTRACT
PURPOSE: To evaluate the efficacy and safety of BOTULAX® in subjects with essential blepharospasm.METHODS: In this study, a total of 250 subjects with essential blepharospasm were enrolled at 15 investigational sites and a total of 220 subjects completed the study. The efficacy and safety were evaluated at weeks 4 and 16 after treatment compared with baseline. In total, 240 subjects were enrolled, treated with the investigational product, and evaluable for the primary efficacy assessment at week 4 after treatment; these subjects were included in the intention-to-treat (ITT) population. With the ITT set as the main efficacy set, efficacy assessment included Jankovic rating scale (JRS), functional disability score, investigator evaluation of global response and quality of life. Safety assessment including the incidence of adverse events was also performed.RESULTS: In terms of the primary efficacy endpoint (i.e., change in JRS total score at week 4 after treatment from baseline [ITT set]), mean change indicated a statistically significant reduction (p < 0.0001) and demonstrated the non-inferiority of the test drug to similar drugs. In terms of the secondary efficacy endpoints, mean change in JRS total score at week 16 after treatment and mean change in functional disability score at weeks 4 and 16 after treatment both exhibited a statistically significant reduction compared with baseline (p < 0.0001 for all). Among the 249 subjects treated with the investigational product in this study, 44 (17.67%) experienced 76 treatment emergent adverse events but no serious adverse events were observed.CONCLUSIONS: Based on the study results, BOTULAX® is considered to be an effective and safe treatment for essential blepharospasm.

BACKGROUND: To present our experience on orbital and periorbital tissue changes after proton beam radiation therapy (PBRT) in patients with intraocular tumors, apart from treatment outcomes and disease control. METHODS: Medical records of 6 patients with intraocular tumors who had been treated with PBRT and referred to oculoplasty clinics of two medical centers (Seoul National University Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center) from October 2007 to September 2014 were retrospectively reviewed. The types of adverse effects associated with PBRT, their management, and progression were analyzed. In anophthalmic patients who eventually underwent enucleation after PBRT due to disease progression, orbital volume (OV) was assessed from magnetic resonance (MR) images using the Pinnacle3 program. RESULTS: Among the six patients with PBRT history, three had uveal melanoma, and three children had retinoblastoma. Two eyes were treated with PBRT only, while the other four eyes ultimately underwent enucleation. Two eyes with PBRT only suffered from radiation dermatitis and intractable epiphora due to canaliculitis or punctal obstruction. All four anophthalmic patients showed severe enophthalmic features with periorbital hollowness. OV analysis showed that the difference between both orbits was less than 0.1 cm before enucleation, but increased to more than 2 cm3 after enucleation. CONCLUSION: PBRT for intraocular tumors can induce various orbital and periorbital tissue changes. More specifically, when enucleation is performed after PBRT due to disease progression, significant enophthalmos and OV decrease can develop and can cause poor facial cosmesis as treatment sequelae.

PURPOSE: To compare the intraocular pressure (IOP) measured using Goldmann-applanation tonometry (GAT) and Tonopen® tonometry and to evaluate the factors influencing the measurement difference in patients with thyroid-associated ophthalmopathy (TAO)-related restrictive strabismus. METHODS: In 50 eyes of 50 patients who were diagnosed with TAO, IOP measurements were taken using both GAT and a Tonopen® and were subsequently compared between the devices. Factors influencing the measurement difference between the devices were determined, including the restriction of eyeball movement, eyeball deviation, exophthalmometry, central corneal thickness, refractive errors, and blood thyroid hormone levels. RESULTS: In the TAO patients, the GAT-measured IOP was higher than for Tonopen® (16.1 ± 4.7 vs. 13.8 ± 4.5 mmHg, respectively, p < 0.001). As the restriction of vertical eyeball movement increased, the IOP difference between the devices also increased (p = 0.037). The absolute IOP difference between the devices was positively correlated with restrictions in vertical eyeball movement (p = 0.027), degree of vertical strabismus (p = 0.021), and central corneal thickness (p ≤ 0.031). CONCLUSIONS: In patients with TAO accompanying vertical eyeball movement restriction, potential errors in IOP measurements should be considered between the different IOP-measuring devices.

PURPOSE: To analyze the features of lacrimal drainage system obstruction confirmed during external dacryocystorhinostomy surgeries and report the surgical outcomes. METHODS: We reviewed the medical records of a total of 769 cases who underwent external dacryocystorhinostomy for primary lacrimal drainage obstruction between 2005 and 2014. Data about detailed location and extent of obstruction were collected intraoperatively. The sites of obstruction were classified into nasolacrimal duct obstruction (NLDO), common canalicular obstruction (CCO), and canalicular obstruction. Lacrimal sac mucosa and lumen were grossly inspected, and the frequency of lacrimal sac changes, such as significant inflammation or fibrosis, was analyzed in cases of CCO or canalicular obstruction. The surgical success rate was also evaluated including effect of lacrimal sac status in the CCO and canalicular obstruction groups. RESULTS: Of 769 cases, primary NLDO with patent canaliculi was diagnosed intraoperatively in 432 cases (56.2%), CCO in 253 (32.9%), and canalicular obstruction in 84 (10.9%). Of 253 cases with CCO, 122 (48.2%) showed clear lacrimal sac lumen, and the other 131 (51.8%) showed significant inflammation or fibrosis of the lacrimal sac. In cases with canalicular obstruction, 35 of 84 (41.7%) showed a clear lacrimal sac, and the other 49 cases (58.3%) cases revealed mucosal changes of the lacrimal sac. The functional success rate was 87.5% for primary NLDO, 75.5% for CCO, and 72.6% for canalicular obstruction. In the CCO group, the functional success rate was lower in cases with significant lacrimal sac change (p = 0.044). CONCLUSIONS: Even in patients with CCO or canalicular obstruction, a large number of cases have lacrimal sac changes, and those changes were associated with lower functional success rate.

PURPOSE: Choristomas represent congenital overgrowth of normal tissues in an abnormal location. The simultaneous presence of epibulbar choristoma and microphthalmos has rarely been reported. The authors report a case of extensive epibulbar choristoma associated with microphthalmos. CASE SUMMARY: A 9-day-old boy with the left eyeball absent from birth was referred to our clinic. A large cornea-like structure covered by keratinized membrane was observed inside the eyelid aperture, therefore buphthalmos or corneal staphyloma with microphthalmos was presumed. At the age of 2 months, a large mass of central conjunctival sac protruded through the left eyelid aperture. Manual reduction could not return the tissue to its original site and the mass immediately protruded again. At the age of 9 months, orbital magnetic resonance imaging showed the small presumed ocular tissue behind the large mass of fat signal in the central anterior orbit, therefore, extensive epibulbar choristoma associated with microphthalmos was diagnosed. At 12 months of age, partial excision of the protruding portion of the mass was performed. Based on pathologic examination, the mass was determined to be a choristoma and cosmetically acceptable appearance with prosthesis was maintained for 10 months after the surgery. CONCLUSIONS: Because there is no vision in extensive choristoma associated with microphthalmos, the treatment goal is cosmetic improvement. Conjunctivoplasty following partial mass excision for prosthesis wearing is a good treatment option.

PURPOSE: To investigate periorbital lipogranuloma cases that developed after autologous fat injection and to determine various treatment outcomes from these cases. METHODS: This retrospective study involved 27 patients who presented with periocular mass (final diagnosis of lipogranuloma) and had history of facial autologous fat injection. The collected data included information on patient sex, age, clinical presentation, number and site of fat injections, interval between injections, duration from injection to symptom onset, fat harvesting site, use of cryopreservation, and treatment outcome. RESULTS: The most common presenting symptom was palpable mass (92.6%), followed by blepharoptosis and eyelid edema. The mean time from injection to symptom onset was 13.6 +/- 29.2 months (range, 2 to 153 months). Patients were managed by intralesional triamcinolone injection (six patients) and surgical excision (three patients); 18 patients were followed without treatment. Among the six patients who underwent intralesional triamcinolone injection, five showed complete resolution, and one showed partial resolution. Among the 18 patients who were followed without management, three showed spontaneous resolution over a 5-month follow-up period. CONCLUSIONS: Lipogranuloma can develop in the eyelid after autologous fat injection into the face. Both surgical excision and intralesional triamcinolone injection yield relatively good outcomes. Simple observation can be a good option because spontaneous resolution can occur in a subset of patients.

PURPOSE: To report a case of eyeball displacement into the ethmoid sinus followed by early surgical intervention and good visual recovery. CASE SUMMARY: A 46-year-old female visited our hospital after she injured the right side of her face. Her visual acuity could not be measured and computed tomography revealed displacement of the right eyeball into the ethmoid sinus, as well as right medial orbital wall fracture and rupture of the right medial rectus muscle. She underwent surgical reduction of the herniated eyeball and surgical correction of the medial orbital wall fracture within 20 hours after the accident. Eighteen months after the surgery, visual acuity of the right eye improved from light perception to 20/28, and her color vision and visual field of the right eye improved to normal range. CONCLUSIONS: Displacement of the eyeball in the orbital wall fracture is very rare, and eyeball displacement into the ethmoid sinus is even rarer. We achieved good visual outcome through early surgical intervention. The early anatomical reduction of the displacement and wall fracture may promote improved final visual outcome in other similar cases.

PURPOSE: The incidence and clinical correlation of MALT1 translocation and chromosomal numerical aberrations in Korean patients with ocular adnexal mucosa associated lymphoid tissue (MALT) lymphoma have not yet been reported. We investigated the incidence and clinicopathologic relationship of these chromosomal aberrations in ocular adnexal MALT lymphomas in a Korean population. METHODS: Thirty ocular adnexal MALT lymphomas were investigated for the t(11;18) API2-MALT1, t(14;18) IgH-MALT1 translocations and chromosomes 3 and 18 aneuploidies using fluorescence in situ hybridization. Patient medical records were reviewed retrospectively for information on demographics and clinical characteristics, including treatment response. RESULTS: The MALT1 gene rearrangement was found in one out of 30 cases. The t(14;18) IgH-MALT1 translocation was demonstrated in only one case (3.3%), and the t(11;18) API2-MALT1 translocation was not found in any of the cases. Trisomy 3 was observed in three ocular adnexal MALT lymphomas (10.0%), and five cases showed trisomy 18 (16.7%). Translocation positive cases also showed trisomy 18. One case of tumor relapse showed trisomy 18 only in the recurrent biopsies. There were no statistically significant correlations between chromosomal aberrations and clinical characteristics and treatment responses. CONCLUSIONS: Translocations involving the MALT1 gene are not common in Korean ocular adnexal MALT lymphomas. The t(14;18) translocation was detected in only one out of 30 cases, and the t(11;18) translocation was not found at all. Furthermore, the chromosomal aberrations found in this study had no prognostic implications.

PURPOSE: Recent reports suggest the association of human papilloma virus (HPV) with retinoblastoma. This study was performed to elucidate whether HPV infection is related to retinoblastoma among Koreans. METHODS: A total of 54 cases diagnosed with retinoblastoma were enrolled from Seoul National University Children's Hospital and Seoul Metropolitan Government-Seoul National University Boramae Medical Center. Presence of human papilloma viral DNA was detected by in situ hybridization in formalin-fixed paraffin-embedded retinoblastoma tissues using both probes against high- and low risk HPV types. RESULTS: The mean age at diagnosis was 22.0 months (range, 1.1 to 98.0 months), and the mean age at enucleation was 27.8 months (range, 1.5 to 112.7 months) among the 54 patients with retinoblastoma. HPV was not detected in any of the retinoblastoma samples using either high risk or low risk HPV probes. CONCLUSIONS: Our study, being the first study in the Korean population, proposes that HPV infection may have no causal relationship with retinoblastoma in Koreans.
