RESUMEN
PURPOSE: Dermatochalasis is a common disorder of the elderly, often requiring upper blepharoplasty. Although it is mainly accepted as a process of aging, its clinical and histological findings vary among patients. The aim of this study was to classify types of dermatochalasis based on their clinical and histological findings. METHODS: This retrospective study included patients with dermatochalasis who had undergone senile blepharoplasty at a single center. Clinical parameters such as margin-to-reflex distance 1 (MRD1), eyelid contour, visual field, and pre-existing medical conditions were assessed. Histological analysis was conducted of eyelid tissues stained with hematoxylin and eosin (H&E) and D2-40 to evaluate dermal edema, inflammation, lymphatic changes, and stromal depth. RESULTS: This study included 67 eyes of 35 patients. The mean age of the patients was 69.0 ± 8.3 years, and the average MRD1 was 1.8 ± 1.3 mm. In correlation analysis, two distinct types of dermatochalasis based on the histological findings were identified: lymphangiectasia-dominant and stromal edema-dominant types. The difference between nasal and temporal side MRD1(NT-MRD1) showed the area under the ROC curve of 0.718 of for distinguishing the two histological types of dermatochalasis was 0.718. CONCLUSION: Our novel classification of senile dermatochalasis based on morphological and histological analysis provides insights into the underlying pathology and may help to predict surgical outcomes and complications.

BACKGROUND: To analyze the morphologic and functional change in traumatic optic neuropathy (TON) divided by the mechanism of optic nerve injury. METHODS: A retrospective analysis of 58 patients who were diagnosed as monocular TON from February 2015 to August 2021 was conducted at in CHA Bundang Medical Center in Seongnam, South Korea. The patients visited the clinic of the department of ophthalmology for more than 6 months and at least 4 times during this period. RESULTS: 44 patients were classified as blunt TON patients, and 14 patients were surgical TON patients. The visual acuity showed significant decrease in traumatic eyes at the first visit after injury compared to fellow eyes and maintained the injured status during the 1-year follow-up period in blunt TON. In surgical TON, the visual acuity slightly improved during 1 month follow-up period. RNFL thickness tended to be decreased at 1 month after first visit blunt TON patients, which was earlier than surgical TON patients. GCIPL thickness showed earlier decreased than RNFL thickness in both blunt and surgical TON patients. CONCLUSIONS: In both blunt and surgical TON eyes, there was a notable thinning in both RNFL and GCIPL, with particularly remarkable reduction in GCIPL in early phase. Therefore, analyzing each retinal layer thickness using OCT in conjunction with assessing visual function would be necessary. This combined approach is not only crucial for understanding clinical courses of each TON, but also predicting the morphological and functional deteriorations in TON.

PURPOSE: We investigated the cytologic findings of primary acquired nasolacrimal duct obstruction (PANDO) based on the thin-prep cytology method using sheath-guided dacryoendoscopy. METHODS: A retrospective review was conducted of 66 cases from 50 patients who were diagnosed with PANDO. Slit-lamp examination, the lacrimal irrigation test, and dacryocystography were performed for the evaluation of PANDO. The dacryocystography (DCG) findings were classified into primary and secondary change. Each patient was treated with transcanalicular dacryoplasty using catheter sheath-guided dacryoendoscopy (RUIDO Fiberscope, Fiber Tech Co., Ltd., Tokyo, Japan) and obtained cytologic specimens. The liquid-based thin-prep cytology method was used for the analysis of histopathology. RESULTS: The cellular detection rate was as follows: epithelial cells with 56 cases (84.8%), 33 cases (50.0%) with inflammatory cells, 1 case (1.5%) with mucin, and bacterial colonies with 2 cases (3.0%). In the dacryoendoscopic findings, all cases of a presence of pus were related to the detection of the columnar epithelium (p = 0.026), while there was no statical significance according to the presence of an epithelial cell. In the DCG findings, the PANDOs with the secondary change showed a higher detection rate than those with the primary change (p = 0.005), and columnar epithelial cells were observed (p = 0.011). The detection rate of inflammatory cells was 50.0% (33/66) and all inflammatory cells were lymphocytes but it was not correlated with clinical findings. One case of mucin (1.5%) and 2 cases of bacterial colonies (3.0%) were presented using liquid-based thin-prep cytology analysis. The overall success rate of transcanalicular dacryoplasty and silicone intubation was 86.4%. CONCLUSION: Liquid based thin prep cytology can be used to analyze histopathological changes of lacrimal passage in PANDO without invasive biopsy. These cytologic findings of lacrimal passage provide a better understanding of the pathogenesis of lacrimal passage in patients with PANDO.

Orbital fibroblasts (OFs) in thyroid-associated ophthalmopathy (TAO) are differentiated from pre-adipocytes and mature adipocytes; increased lipid and fat expansion are the major characteristics of ophthalmic manifestations. Human placental mesenchymal stem cells (hPMSCs) were reported to immunomodulate pathogenesis and suppress adipogenesis in TAO OFs. Here, we prepared transforming growth factor ß (TGFß, 20 ng/mL)-treated hPMSCs (TGFß-hPMSCs) in order to enhance anti-adipogenic effects in vitro and in TAO mice. TAO OFs were grown in a differentiation medium and then co-cultured with hPMSCs or TGFß-hPMSCs. TAO OFs were analyzed via quantitative real-time polymerase chain reaction, Oil red O staining, and western blotting. The results showed that TGFß-hPMSCs reduced the expression of adipogenic, lipogenic, and fibrotic genes better than hPMSCs in TAO OFs. Moreover, the adipose area decreased more in TAO mice injected with TGFß-hPMSCs compared to those injected with hPMSCs or a steroid. Further, TGFß-hPMSCs inhibited inflammation as effectively as a steroid. In conclusion, TGFß-hPMSCs suppressed adipogenesis and lipogenesis in vitro and in TAO mice, and the effects were mediated by the SMAD 2/3 pathways. Furthermore, TGFß-hPMSCs exhibited anti-inflammatory and anti-fibrotic functions, which suggests that they could be a new and safe method to promote the anti-adipogenic function of hPMSCs to treat TAO patients.

BACKGROUND: To investigate the lacrimal drainage system (LDS) from the punctum to the inferior meatus and the clinical outcomes of transcanalicular endoscopic dacryoplasty and silicone intubation through dacryoendoscopy in patients with primary acquired nasolacrimal duct obstruction (PANDO). METHODS: We conducted a retrospective chart review of 203 cases from 156 patients who underwent dacryoendoscopy (FT-203F; Fibertech Co., Tokyo, Japan) and sheath-guided silicone intubation for PANDO from December 2014 to March 2018. Clinical characteristics, tear meniscus height, irrigation test, dacryocystographic findings, and dacryoendoscopic findings related to clinical factors and surgical outcomes were evaluated. RESULTS: The study population consisted of 44 males and 119 females (mean age, 60.4 ± 13.6 years). The mean epiphora duration was 3.8 ± 4.8 years. Dacryoendoscopic findings revealed that the following factors were associated with LDS obstruction (% cases): mucus, 39.9%; fibrotic membrane, 19.2%; stones, 9.4%; granulation, 8.9%; and stenosis, 2.7%. The locations of obstruction were as follows (% cases): nasolacrimal duct, 35.7%; canaliculus, 33.0%; sac, 27.6%; and inferior meatus, 3.5%. The types of LDS obstruction were classified into two groups: secretory group (n = 118) that included mucus, stones, and granulation, and structural group (n = 85) associated with the membrane and stenosis; the pattern of them was divided into focal (n = 134) and diffuse (n = 76). The overall success rate was 86.2%. The success rate of the structural group (95.3%) was significantly higher than that of the secretory group (79.7%) (p = 0.001). All membranous obstruction cases at the inferior meatus were treated successfully, regardless of the irrigation test results. The success rate of the focal group (93.1%) was significantly higher than that of the diffuse group (74.0%) (p = 0.003). CONCLUSIONS: Dacryoendoscopic findings were informative regarding the clinical factors leading to LDS in PANDO patients. Mucus and stones in the lacrimal sac were common findings of functional lacrimal duct obstruction. Membranous obstruction and stenosis could be managed by recanalization under direct visualization. Transcanalicular endoscopic dacryoplasty and silicone intubation is considered to be a safe and effective procedure, sparing the patient from bony destruction in selected cases of PANDO.

Human pluripotent stem cell-derived neural progenitor cells (NPCs) have the potential to recover from nerve injury. We previously reported that human placenta-derived mesenchymal stem cells (PSCs) have neuroprotective effects. To evaluate the potential benefit of NPCs, we compared them to PSCs using R28 cells under hypoxic conditions and a rat model of optic nerve injury. NPCs and PSCs (2 × 106 cells) were injected into the subtenon space. After 1, 2, and 4 weeks, we examined changes in target proteins in the retina and optic nerve. NPCs significantly induced vascular endothelial growth factor (Vegf) compared to age-matched shams and PSC groups at 2 weeks; they also induced neurofilaments in the retina compared to the sham group at 4 weeks. In addition, the expression of brain-derived neurotrophic factor (Bdnf) was high in the retina in the NPC group at 2 weeks, while expression in the optic nerve was high in both the NPC and PSC groups. The low expression of ionized calcium-binding adapter molecule 1 (Iba1) in the retina had recovered at 2 weeks after NPC injection and at 4 weeks after PSC injection. The expression of the inflammatory protein NLR family, pyrin domain containing 3 (Nlrp3) was significantly reduced at 1 week, and that of tumor necrosis factor-α (Tnf-α) in the optic nerves of the NPC group was lower at 2 weeks. Regarding retinal ganglion cells, the expressions of Brn3a and Tuj1 in the retina were enhanced in the NPC group compared to sham controls at 4 weeks. NPC injections increased Gap43 expression from 2 weeks and reduced Iba1 expression in the optic nerves during the recovery period. In addition, R28 cells exposed to hypoxic conditions showed increased cell survival when cocultured with NPCs compared to PSCs. Both Wnt/ß-catenin signaling and increased Nf-ĸb could contribute to the rescue of damaged retinal ganglion cells via upregulation of neuroprotective factors, microglial engagement, and anti-inflammatory regulation by NPCs. This study suggests that NPCs could be useful for the cellular treatment of various optic neuropathies, together with cell therapy using mesenchymal stem cells.

PURPOSE: We investigated the etiology of punctal stenosis based on the histopathological features of puncta and clinical correlations in punctal stenosis patients. METHODS: A retrospective review was conducted of 69 cases from 38 patients who were diagnosed with punctal stenosis. Slit-lamp examination, the lacrimal irrigation test, dacryocystography, and spectral domain-optical coherence tomography were performed for the evaluation of punctal occlusions. For treatment, punctoplasty using a punch biopsy with or without silicone tube insertion and histopathological examinations were performed. RESULTS: The pathological features of the punctal membranes were classified into two types of epithelia: squamous (95.7%, 66/69) and columnar (4.3%, 3/69). The squamous epithelial specimens were divided into three groups: fibrous tissue (66.8%, 48/69), goblet cells (21.8%, 48/69), and keratinization (4.3%, 3/69). Most of the subepithelial pathology was fibrosis (82.6%, 57/69), and inflammation was noted in 17.4% (12/69) of the patients. Subepithelial fibrosis was the most common pathological feature in patients exhibiting stenosis with a squamous epithelium, while inflammation was more strongly correlated with patients with a columnar epithelium. However, there was no correlation between the histopathological findings and treatment outcomes. CONCLUSION: Our histopathological findings suggest that primary fibrosis of the stenotic punctum was caused by intrinsic inflammation of the puncta rather than spreading from the conjunctiva or eyelid. Punctoplasty was effective in treating punctal stenosis, regardless of the epithelial type.

PURPOSE: Hyaluronic acid gel (HAG) fillers provide a versatile and safe correction method for a sunken superior sulcus (SS) resulting from soft tissue volume loss occurring with aging, previous surgery, or enophthalmos related to trauma or phthisis bulbi. The purpose of this study was to report the long-term clinical outcomes of filler injection for soft-tissue augmentation in patients with a deep SS. DESIGN: Retrospective, interventional case series METHODS:: The medical records of 27 patients (32 eyes) with deep superior sulci were reviewed. Twenty injections of hyaluronic acid fillers (Restylane; Q-med AB, Uppsala, Sweden) were performed in the retrobulbar (RB) area, and 15 injections were performed in the SS. Pre- and post-treatment photographs were taken. MAIN OUTCOMES MEASURES: Visual acuity for seeing eyes, intraocular pressure, exophthalmos measurement, marginal reflex distance 1, interpalpebral fissure, tarsal platform show, and SS hollowing depth grade RESULTS:: Enophthalmos corrections were 1.3â±â0.8âmm (Pâ<â0.001) and the SS hollowing grade decrease was 1.2â±â0.9 (Pâ<â0.01) after 1 month of RB injection. Enophthalmos corrections were 0.1â±â0.4âmm (Pâ=â0.317) and the SS sunkeness grade decrease was 1.7â±â0.8 (Pâ<â0.001) after 1 month of SS injection. The amount of filler to correct enophthalmos of 1âmm was 0.83â±â0.53âmL using the RB injection. Using Kaplan-Meier survival analysis, the mean period of maintenance for deep SS correction was 9.1 months for RB injections and 8.5 months for SS injections. CONCLUSION: Retrobulbar (RB) hyaluronic acid gel (HAG) injections corrected enophthalmos and a deep SS, while SS injections corrected only a deep SS. These 2 techniques of RB and direct sulcus injection are safe and effective methods for the correction of a deep SS.

PURPOSE: This study aims to investigate the surgical outcomes of a novel epiblepharon correction method based on the pathologic features of epicanthal tissue. The correlation between the pathology and clinical presentations was also studied. METHODS: This retrospective study included 72 eyelids of 36 children with epiblepharon and epicanthal folds. From July 2013 to March 2016, epicanthal tension-releasing procedure of subdermal fibrinolysis with orbicularis oculi ring myotomy were performed in 36 children. Photographs before and after operation were analyzed with Image J program. A clinical severity of the epiblepharon was scored based on the lower eyelid skin fold height (mild to severe). Subdermal fibrosis index was defined as the portion of fibrosis in low power field (× 40) and eyelid contour was assessed with custom software (MATLAB). Eighty eyelids without eyelid pathology were analyzed to establish the normal eyelid contour. The epicanthal tissues were classified into three categories: mild, moderate, and severe fibrosis. RESULTS: The mean age of the patients was 5.5 years. Intercanthal distance (ICD) ratio was defined as Inner ICD (IICD)/outer ICD (OICD). The IICD/OICD was 0.41 in the severe epiblepharon group that is significantly longer compared to that of the mild epiblepharon group (0.38). Subdermal fibrosis index was higher in severe epiblepharon group. Eyelid contour was normalized and the cilia touch was resolved after the epicanthal tension-releasing procedure. CONCLUSION: Epicanthal tension-releasing procedure with orbicularis oculi ring myotomy achieved favorable surgical outcomes. Clinical correlations with pathologic findings and satisfactory results of the procedure suggest that medial epicanthal fibrosis is the main pathologic feature causing epiblepharon and epicanthal folds.

PURPOSE: To review indications and clinical outcomes in a series of orbitocranial tumors treated surgically through a transorbital extradural approach without craniotomy. METHODS: In this retrospective case series, all patients who underwent surgery through a transorbital extradural approach without craniotomy for benign orbitocranial tumors involving the dura or extending into the anterior or middle cranial fossae were analyzed. RESULTS: Twenty-seven patients (20 females and 7 males) were included. Median age was 47.0 years (range: 6-74 years) and median follow-up time was 43.5 months (range: 3-148 months). The median preoperative best-corrected visual acuity (logMAR) was improved from 0.35 (range: 0-2.6) to 0.1 (range: 0-2.6) at the last follow-up (p < 0.03). The mean ± SD preoperative exophthalmos significantly decreased from 20.4 ± 3.4 mm to 13.1 ± 3.5 mm at the last follow-up visit (p < 0.01). Four postoperative complications were noted and included one case each of ptosis, numbness, diplopia (transient for 6 months), and cranial nerve VI palsy (transient for 4 months). CONCLUSIONS: The transorbital extradural approach provides access to the deep orbit and adjacent extradural cranial spaces. Benign orbital tumors that have eroded through the orbital roof, are located in the orbital apex abutting the anterior cavernous sinus and tumors requiring debulking are all processes that can be potentially approached through the transorbital extradural route. Compared to open craniotomy, the incision is smaller, the access more direct and specific risks of open craniotomy are reduced.

PURPOSE: To investigate the effect of epiblepharon surgery on motor and sensory function in children with epiblepharon and concomitant strabismus. METHODS: Among 564 patients who underwent epiblepharon correction surgery from May 2016 to April 2023, 45 children who were examined for strabismus were included in the study. Preoperative and postoperative visual acuity, refraction, and angle of deviation were analyzed. For those with significant angle of deviation, additional stereopsis, sensory fusion, and returning time were retrospectively investigated. The angle of deviation was examined by one examiner at distance and near. RESULTS: The mean age of 45 children (18 boys and 27 girls) was 6.8 ± 2.9 years. Fifteen had significant strabismus at the time of epiblepharon surgery. Visual acuity improved in both the total and strabismus groups. Improvement in stereopsis and fusion was also observed in the strabismus group. The angle of deviation showed no difference in both groups. CONCLUSIONS: Epiblepharon could affect ocular manifestations of strabismus as shown in this study. The authors suggest strabismus treatment be continued after epiblepharon surgery, with improved sensory function. Further evaluation with larger groups is needed in the future.

To analyze the clinical characteristics of mucinous obstruction diagnosed by dacryoendoscopy and compared the cytological changes with membranous obstruction using a modified liquid-based thin prep cytology method. A retrospective chart review was conducted on 53 eyes of 51 patients with mucus obstruction based on dacryoendoscopic findings from January 2022 to October 2022. Liquid-based thin-prep cytology was performed by irrigating the inside of the nasolacrimal drainage system with saline during dacryoendoscopy-guided silicone tube intubation. Pathological findings were analyzed through a comparison of mucinous obstruction with membranous obstruction as determined by dacryoendoscopic findings. The modified liquid-based thin prep cytology technique had a higher cytology detection rate across all cases. Mucinous obstruction exhibited a significantly higher number of successful canalicular irrigation test cases compared to membranous obstruction. In mucinous obstruction, epithelial squamous cells were more frequently detected in pre-sac obstruction, whereas columnar epithelial cells were predominant in post-sac obstruction. Inflammatory cells showed a stronger correlation with primary change and post-sac obstruction. Bacterial colonies were observed exclusively in cases of mucinous obstruction. The use of a modified liquid-based thin prep cytology method enables the examination of histopathological changes in the lacrimal passage in primary acquired nasolacrimal duct obstruction (PANDO), particularly in cases of mucinous obstruction, without the need for invasive biopsies. These findings enhance the understanding of the etiopathogenesis of mucinous obstruction, complementing knowledge of membranous obstruction in PANDO.

Background: Graves' ophthalmopathy (GO) is characterized by upper eyelid retraction (UER), the most prevalent clinical sign. We aimed to assess the clinical efficacy of a multimodal combination of steroids, 5-fluorouracil (5-FU), and botulinum neurotoxin A (BoNT-A) injections in managing UER with GO and analyze the clinical factors in relation to the injection response. Methods: A total of 37 eyes from 23 patients were enrolled for UER with GO. At the endocrinology clinic, the patients were referred to the ophthalmology clinic after taking antithyroid medication for an average of 5.76 months (13 patients), while 10 patients were initially diagnosed with GO and referred to the endocrinology clinic for management of the thyroid hormone function. They performed an orbital computed tomography (CT) scan and measured the cross-sectional area of the orbit, orbital fat, and each extra ocular muscle (EOM) except for the inferior oblique muscle 4 mm behind the eyeball. Each of the EOMs and orbital fat were calculated as a ratio to the total orbit area. A total of 0.1 cc of triamcinolone (40 mg/mL), dexamethasone (5 mg/mL), 5-FU, and BoNT-A (2.5 units) was injected transconjunctivally. Medical records were examined and photographs were utilized to assess MRD1, inferior palpebral fissure (IPF), and lid lag during down gaze before and after the injection. The patients were divided into two groups: responders (more than 1 mm decrease in MRD1 after injection) and non-responders. During the follow-up period (11.0 ± 11.6 months), any potential adverse effects were monitored. Results: CAS decreased from 3.0 ± 0.8 to 1.4 ± 0.5 after the injection, and MRD1 decreased from 5.0 ± 0.9 mm to 4.5 ± 1.3 mm. Sixty percent of the patients were responders. Before and after the injection, the difference between IPF and MRD1 in responders was 0.60 ± 1.10 mm and 0.90 ± 0.90 mm, respectively, whereas, in non-responders, it was -0.57 ± 0.88 mm and -0.15 ± 0.75 mm, respectively. In the responders, pre-injection IPF and FT4 were significantly higher (p < 0.05). Responders had a larger EOM cross-sectional area (153.5 ± 18.0 mm2), including a larger lateral rectus muscle cross-sectional area (37.6 ± 9.7 mm2) than non-responders (132.0 ± 27.9 mm2; 29.1 ± 8.1 mm2). In responders, the treatment effect on IPF and MRD1 remained consistent at 1.2 ± 3.4 mm and 1.2 ± 1.6 mm, respectively, during the latest follow-up assessment. Conclusions: The combination injection of corticosteroids, 5-FU, and BoNT-A would be effective, especially, in patients with hyperthyroidism and an elongated IPF. Additionally, an increase in EOM cross-sectional area on CT, up to 150 mm2, may serve as an additional positive indicator for the use of multimodal injections in UER with GO.
RESUMEN
Background/Objectives: IgG4-related ophthalmic disease (IgG4-ROD), characterized by lymphoplasmacytic infiltration, fibrosis, and elevated IgG4 levels, presents diagnostic challenges while offering insights into immune-mediated inflammatory disorders. The aim of this study was to comprehensively examine the clinical features and outcomes of IgG4-ROD. Materials and Methods: A retrospective study was conducted on 33 patients diagnosed with IgG4-ROD, fulfilling the American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) criteria. The demographic characteristics of the IgG4-ROD patients were compared with those of 37 patients diagnosed with IgG4-related disease (IgG4-RD) in departments other than ophthalmology (IgG4-nonROD) at the same hospital during the same period. The patients diagnosed with IgG4-ROD were initially treated with glucocorticosteroid (GCS) monotherapy, GCS combined with steroid-sparing agents (SSAs; mycophenolate mofetil, azathioprine, hydroxychloroquine), biologic agent (rituximab) monotherapy, or watchful waiting. The primary outcome was the assessed treatment response at 6 months, and the secondary outcome was the evaluation of recurrence at 1 year after initial treatment. A response was evaluated as the absence of ocular signs and symptoms, either clinically or radiologically. Results: Eyelid swelling (17 patients, 51.5%) was the most common symptom, and lacrimal gland (17 patients, 51.5%) was the most frequent site of involvement. The response rate for GCS monotherapy was 33.3% (3 out of 9 patients), while the response rate for GCS combined with SSA was 60.0% (9 out of 15 patients). The lacrimal gland group demonstrated a significantly higher treatment response compared to the non-lacrimal gland group (66.7% vs. 20.0%, p = 0.013), and the combination of GCS and SSA resulted in a significantly higher treatment response than the GCS monotherapy (77.8% vs. 33.3%, p = 0.045). The group including hydroxychloroquine (HCQ), which comprised 5 out of 33 patients (15.2%), showed no recurrence at 1 year. Conclusions: The combination therapy of GCS and SSA for IgG4-ROD can be considered an effective treatment approach and HCQ could be considered as a potential adjunctive therapy for IgG4-ROD.
RESUMEN
Purpose: We report a patient who initially visited the ophthalmology clinic for a vision loss diagnosed with Erdheim-Chester Disease (ECD). Observations: ECD is a rare non-Langerhans cell histiocytosis characterized by multisystemic organ involvement and poor prognosis. Our patient had complete vision loss due to prominent orbital involvement before any systemic symptoms appeared. This case demonstrates variable clinical manifestations of ECD. Conclusions and importance: Painless bilateral proptosis with poor response to steroid treatment should prompt consideration for ECD and systemic evaluation. In addition, in the absence of typical clinical manifestations, a thorough evaluation of the biopsy can be crucial for an accurate diagnosis.
RESUMEN
The possible genetic variants associated with blepharospasm (BSP) and facial dystonia have been investigated. Although genetic variants associated with BSP have been extensively studied, the contribution of single-nucleotide polymorphisms towards this condition remains poorly understood. In addition, the etiology of BSP remains to be fully elucidated. Therefore, the present study aimed to assess the role of polymorphisms in the torsin 1A (TOR1A), dopamine receptor D (DRD)2 and DRD5 genes in South Korean patients with BSP. Furthermore, the role of genetic variants of these three aforementioned genes was investigated. A prospective case-control study was established, where 56 patients with BSP and 115 healthy controls were recruited at the Department of Ophthalmology of CHA Bundang Medical Center (Seongnam, South Korea) using single nucleotide polymorphisms analysis by real-time PCR. The TOR1A rs1182CC/DRD5 rs6283TC genotype combination was found to be associated with decreased BSP risk [adjusted odds ratio (AOR), 0.288; P=0.013]. DRD5 rs6283 was observed to be associated with the periocular type of BSP in the co-dominant (for the TC genotype; AOR, 0.370; P=0.029) and dominant models (AOR, 0.406; P=0.029). The recessive model of TOR1A rs1801968 (AOR, 0.245; P=0.030), and the recessive (AOR, 0.245; P=0.029) and over-dominant models (AOR, 2.437; P=0.019) of DRD2 rs1800497 were found to be associated with superior responses to botulinum neurotoxin A (BoNT) treatment. By contrast, dominant (AOR, 0.205; P=0.034) and additive (AOR, 0.227; P=0.030) models of DRD5 rs6283 were associated with poor responses to BoNT treatment. To conclude, these results suggested that DRD2 rs1800497 can confer genetic susceptibility to BSP responses to BoNT treatment, whereas the TOR1A rs1182CC/DRD5 rs6283TC genotype combination appeared to contribute to the association with BoNT efficacy in BSP.
RESUMEN
(1) Background: We aim to find a novel blink parameter in nasolacrimal duct obstruction (NDO) patients and analyze parameters that could reflect subjective symptoms and objective indicators at the same time through a blink dynamic analysis. (2) Methods A retrospective study was conducted with 34 patients (48 eyes) who underwent lacrimal passage intubation (LPI) and 24 control groups (48 eyes). All patients' blink patterns were measured using an ocular surface interferometer before and after LPI, including total blink (TB) and partial blink (PB) and the blink indices blink time (BT), lid closing time (LCT), closure time (CT), lid opening time (LOT), interblink time (IBT), closing speed (CS) and opening speed (OS). The tear meniscus height (TMH) was measured, and the questionnaire "Epiphora Patient's Quality of Life (E-QOL)," which includes daily activity restriction as well as static and dynamic activities, was completed. (3) Results: Compared to CT and the ratio of CT during BT (CT/BT) in control (89.4 ± 20.0 msec, 13.16%), those in NDOs were longer (140.3 ± 92.0 msec, 20.20%) and were also related to TMH. After LPI, CT and CT/BT were recovered to 85.4 ± 22.07 msec, 13.29% (p < 0.001). CT and CT/BT showed a positive correlation with the E-QOL questionnaire score, particularly with dynamic activities. (4) Conclusions: CT and CT/BT, which are objective indicators associated with subjective symptoms of patients, are considered new blink indices for the evaluation of NDO patients with Munk's score.
RESUMEN
In this retrospective study, we compared and analyzed two groups of patients who underwent silicone tube intubation (STI) to treat congenital nasolacrimal duct obstruction (CNDO). We employed dacryoendoscopy to visualize the lacrimal pathways of one group. In total, 85 eyes of 69 patients were included (52 of 41 patients in the non-dacryoendoscopy and 33 eyes of 28 patients in the dacryoendoscopy group). Clinical characteristics, dacryoendoscopic findings, and surgical outcomes were evaluated. The overall STI success rate was 91.8%, and the success rate was significantly higher in the dacryoendoscopy versus non-dacryoendoscopy group (97.0% and 88.5%, respectively). For patients < 36 months of age, the success rate was 100% (23 eyes). All patients with Hasner valve membranous obstructions were younger than 36 months and had structural obstructions of the lacrimal drainage system (LDS) (p = 0.04). However, in patients lacking Hasner valve obstructions, LDS secretory (50.0%) and structural (50%) obstructions occurred at similar rates, which did not vary by age. Dacryoendoscopy-assisted STI enhanced the therapeutic efficacy of CNDO and identified diverse CNDO etiologies beyond Hasner valve obstructions. These findings emphasize the potential advantages of dacryoendoscopy in surgical treatment for CNDO patients.
RESUMEN
PURPOSE: A systematic review of the literature on diagnostic and therapeutic indications, techniques, and complications of dacryoendoscopy (DE) was performed. METHODS: The authors performed a PubMed search of articles published in English on DE. Data were collected and classified according to the categories of the disease. The clinical outcomes and limitations were particularly analyzed. RESULTS: The lacrimal drainage system from the canaliculus to the inferior meatus could be examined based on the specific anatomical features by DE. The canalicular mucosa is smooth and brightly colored, the lacrimal sac shows covering mucosa with good vascularization and the nasolacrimal duct is lined with bright tubular mucosal folds. DE allows direct visualization of the detailed internal condition of the lacrimal disorders, to directly diagnose the site of obstruction with accuracy and address the causes and recanalize the lacrimal drainage system using assisted micro lacrimal surgical instruments in the tearing patients. CONCLUSIONS: Better visualization of the lacrimal canal with DE improves the understanding of physiology and precise identification of the obstructing lesions, both of which are the key to a comprehensive management for the tearing patients.

(1) Background: We constructed scores for moderate-to-severe and muscle-predominant types of Graves' orbitopathy (GO) risk prediction based on initial ophthalmic findings. (2) Methods: 400 patients diagnosed with GO and followed up at both endocrinology and ophthalmology clinics with at least 6 months of follow-up. The Score for Moderate-to-Severe type of GO risk Prediction (SMSGOP) and the Score for Muscle-predominant type of GO risk Prediction (SMGOP) were constructed using the machine learning-based automatic clinical score generation algorithm. (3) Results: 55.3% were classified as mild type and 44.8% were classified as moderate-to-severe type. In the moderate-to-severe type group, 32.3% and 12.5% were classified as fat-predominant and muscle-predominant type, respectively. SMSGOP included age, central diplopia, thyroid stimulating immunoglobulin, modified NOSPECS classification, clinical activity score and ratio of the inferior rectus muscle cross-sectional area to total orbit in initial examination. SMGOP included age, central diplopia, amount of eye deviation, serum FT4 level and the interval between diagnosis of GD and GO in initial examination. Scores ≥46 and ≥49 had predictive value, respectively. (4) Conclusions: This is the first study to analyze factors in initial findings that can predict the severity of GO and to construct scores for risk prediction for Korean. We set the predictive scores using initial findings.
