Conclusão: A complexidade da lesão está associada ao sucesso anatômico e funcional finais, e o resultado do teste de Zappia-Milder guarda relação com a queixa de epífora.

ABSTRACT Objective: To assess the clinical-epidemiological profile of patients with eyelid trauma associated with lacrimal canaliculus laceration, factors related to trauma and surgical intervention, and to evaluate post-surgical anatomical and functional success. Methods: A retrospective and longitudinal analytical study was conducted, in which chart analysis was performed for patients with eyelid trauma and associated canalicular injury, who were operated on from January 1, 2015, to July 31, 2022. Patients were selected and contacted for in-person evaluation and tests to analyze post-surgical anatomical and functional success. Results: We selected 84 patients, and 28 of them attended the in-person evaluation. Anatomical success was achieved in 64.3% of them, and functional success in 60.71% of the cases. Age was associated with trauma traumatic mechanism. Conclusion: Injury complexity is associated with final anatomical and functional success, and the result of the Zappia-Milder test is related to patients' complaints of epiphora.

Management of periocular keratinocyte carcinomas with Mohs micrographic surgery and predictors of complex reconstruction: a retrospective study

Abstract Background Skin cancer is the most frequent cancer worldwide and the most frequent periocular tumor. Keratinocyte Carcinomas (KC) located in periorificial areas, such as periocular tumors, are considered high-risk tumors. Mohs Micrographic Surgery (MMS) is considered the first line for the treatment of high-risk KC, providing a lower recurrence rate than conventional wide excision. Objective To describe the clinical-pathological features of periocular KC treated with MMS in a tertiary university center in Chile. Methods A single-center, retrospective study of patients with KC located on the periocular area, that underwent MMS between 2017‒2022. MMS details were recorded. Results One hundred thirteen patients with periocular carcinomas were included. The mean age was 59 ± 13 years; 52% were women. The most frequent location was the medial canthus (53%), followed by the lower eyelid (30.1%). The most frequent BCC histology was the nodular variant (59.3%). Regarding MMS, the average number of stages was 1.5 ± 0.7, and 54% of the cases required only 1 stage to achieve clear margins. To date, no recurrence has been reported. Tumors larger than 8.5 mm in largest diameter or 43.5 mm2 were more likely to require complex reconstruction. Study limitations Retrospective design and a relatively low number of patients in the SCC group. Possible selection bias, as larger or more complex cases, may have been referred to oculoplastic surgeons directly. Conclusion The present study confirms the role of MMS for the treatment of periocular KCs. Periocular KCs larger than 8.5 mm might require complex reconstruction. These results can be used to counsel patients during pre-surgical visits.

Evaluation of Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum

ABSTRACT Purpose: To assess Meibomian gland dysfunction using meibography in patients with xeroderma pigmentosum and correlate with ocular surface changes. Methods: This cross-sectional study evaluated patients with xeroderma pigmentosum. All patients underwent a comprehensive and standardized interview. The best-corrected visual acuity of each eye was determined. Detailed ophthalmic examination was conducted, including biomicroscopy examination of the ocular surface, Schirmer test type I, and meibography, and fundus examination was also performed when possible. Meibomian gland dysfunction was assessed by non-contact meibography using Oculus Keratograph® 5M (OCULUS Inc., Arlington, WA, USA). Saliva samples were collected using the Oragene DNA Self-collection kit (DNA Genotek Inc., Ottawa, Canada), and DNA was extracted as recommended by the manufacturer. Factors associated with abnormal meiboscores were assessed using generalized estimating equation models. Results: A total of 42 participants were enrolled, and 27 patients underwent meibography. The meiboscore was abnormal in the upper eyelid in 8 (29.6%) patients and in the lower eyelid in 17 (62.9%). The likelihood of having abnormal meiboscores in the lower eyelid was 16.3 times greater than that in the upper eyelid. In the final multivariate model, age (p=0.001), mutation profile (p=0.006), and presence of ocular surface malignant tumor (OSMT) (p=0.014) remained significant for abnormal meiboscores. For a 1-year increase in age, the likelihood of abnormal meiboscores increased by 12%. Eyes with OSMT were 58.8 times more likely to have abnormal meiboscores than eyes without ocular surface malignant tumor. Conclusion: In the final model, age, xeroderma pigmentosum profile, previous cancer, and clinical alterations on the eyelid correlated with a meiboscore of ≥2. Meibomian gland dysfunction was common in patients with xeroderma pigmentosum, mainly in the lower eyelid. The severity of Meibomian gland dysfunction increases with age and is associated with severe eyelid changes.

Abstract Introduction : Juvenile myoclonic epilepsy (JME) is an epileptic syndrome with onset in childhood and adolescence with myoclonus, absences, and generalized tonic-clonic seizures. Reflex stimuli such as sensitivity to light or photosensitivity, eyelid opening and closing, and praxis induction produce epileptiform discharges and seizures. These reflex triggers are not all system atically studied. Objective : Examine reflex features in patients with JME. Methods : One hundred adolescents and adults with JME who received different anti-seizure treatments were evaluated consecutively. A standard electroen cephalogram was performed with an intermittent light stimulation (SLI) protocol and another for the evaluation of praxias through neurocognitive activity (CNA). The statistical analysis was descriptive and of correlation with a p > 0.05. Results : Current age was 28+/-11 (14-67). The seizure began at 15 years +/-3 (Range 8-25 years). They pre sented myoclonus and generalized tonic-clonic seizures in 58%. 50% received valproic acid and 31% continued with seizures. Epileptiform discharges at rest 20%; hy perventilation 30%; eyelid opening and closing 12%; photoparoxysmal response in SLI 40%; CNA 23%. Higher percentage of discharges and delay in performing CNA in those who presented seizures. Valproic acid com pared to other drugs did not demonstrate superiority in seizure control. Conclusions : These findings confirm the importance of studying reflex traits for diagnosis, follow-up, and therapeutic control.

Reconstrucción palpebral postumorectomía. Presentación de un caso / Lower eyelid reconstruction after lumpectomy. A case report

Algunos pacientes en la tercera edad desarrollan con frecuencia diversas enfermedades, entre ellas se encuentra el cáncer de piel y la predisposición a la aparición de tumores, tanto en los párpados como en la conjuntiva. Entre los tumores epiteliales malignos se destacan: el carcinoma basocelular y el carcinoma epidermoide; con menor frecuencia, el carcinoma de células de Meibomio y el melanoma palpebral, y raramente, el carcinoma de células de Merkel. Por esta causa, se realizó la presentación de un caso clínico que recibió tratamiento en el Servicio de Cirugía Plástica del Hospital Vladimir Ilich Lenin, de Holguín, al cual se le aplicó la técnica de Mustardé por presentar tumor del párpado inferior. El objetivo fue presentar un paciente con reconstrucción palpebral postumorectomía y mostrar su resultado funcional y estético postoperatorio. Este caso evolucionó satisfactoriamente, sin aparición de complicaciones transoperatorias o postoperatorias.

Some elderly patients frequently develop various diseases, including skin cancer as well as a predisposition to the appearance of tumours, both in the eyelids and conjunctiva. Basal cell carcinoma and epidermoid carcinoma stand out among the malignant epithelial lesions; meibomian cell carcinoma and palpebral melanoma which are less common, and Merkel cell carcinoma rarely known. We present a male patient who received treatment in the plastic surgery service at "Vladimir Ilich Lenin" Hospital, in Holguín, to which Mustardé technique was applied for a tumour of the lower eyelid. An eyelid reconstruction was performed after lumpectomy which allowed us to show a postoperative functional and aesthetic result. This case evolved satisfactorily, without the appearance of intraoperative or postoperative complications.

Comparison of the effect of tea tree oil eye gel with standard treatment in patients with anterior blepharitis: An open-label clinical trial

Purpose: Daily cleansing of eyelids is very important to carry out a successful blepharitis treatment. However, there are no therapeutic guidelines for blepharitis. The aim was to compare the symptomatic relief of anterior blepharitis using Blephamed eye gel, a cosmetic product, versus standard treatment. Methods: The study was a prospective, interventional open label clinical trial at a university?based hospital. The test population was subjects aged 18–65 years who presented with mild to moderate anterior blepharitis. Eyelid hygiene was applied twice a day. At each visit, a detailed assessment of symptomatology was carried out. A two?way repeated measure mixed model ANOVA was used to compare two groups by time. Results: In total, 61 patients with mean age of 60.08 ± 16.69 years were enrolled in the study including 30 patients in standard group and 31 patients in Blephamed group. Two groups did not differ in terms of age (P = 0.31) and eye laterality (P = 0.50). The baseline scores of erythema, edema, debris, and symptoms as well as total score were similar between two groups (all P values >0.50). Two groups became different for all these parameters at day 45 (all P values <0.001). Significant interaction was detected between time and intervention groups for all severity parameters of blepharitis as well as total score (all P values <0.001). Conclusion: Eyelid hygiene with Blephamed more significantly decreased symptoms of anterior blepharitis compared to standard treatment.

Giant Eyelid Eccrine Hidrocystoma: A Case Report

Aims: To report a case of a rare giant eyelid eccrine hidrocystoma confirmed on histopathological examination and successful surgical excision with no recurrence.Presentation of Case: A young male presented with a mass over his eyelid which was gradually increasing in size, leading to drooping of the upper eyelid with no other associated symptoms. The mass 20x15x10 mm was present over the upper lid, non-mobile, non-tender, and firm. On the CT scan, a well-defined round to oval hypodense cystic mass was seen to be originating from the left upper eyelid. The cyst was excised and sent for histopathological analysis. The histological appearance of cystic spaces lined by cuboidal epithelium and containing mucinous fluid was suggestive of eccrine hidrocystoma. There was no recurrence till 2 months of follow-up.Conclusion: Eccrine hidrocystomas are 1-6 mm in size, generally 4 mm, and cysts larger than 10 mm are rare. Larger cysts have been described as “giant eccrine hidrocystoma.” Giant eyelid eccrine hidrocystoma is an unusual condition of the eyelid that must be considered in the differential diagnosis of eyelid tumours. They can be managed by complete surgical excision although recurrences are found to be common.

Assessments of the ocular surface and meibomian gland morphology in patients with treatment-naive acne vulgaris / Avaliação da superfície ocular e da morfologia das glândulas meibomianas em pacientes com acne vulgar virgens de tratamento

ABSTRACT Purpose: To investigate ocular surface and meibomian glands in patients with treatment-naive acne vulgaris. Methods: The Ocular Surface Disease Index (OSDI) questionnaire, invasive tear film breakup time, fluorescein staining of the ocular surface, and Schirmer II test were performed for all subjects. Total eyelid and meibomian gland secretion scores were assessed. Non-contact meibography was performed with the Sirius corneal topographic device. Results: The right eyes of 35 patients with acne vulgaris and 35 healthy volunteers were included the study. While the OSDI and staining scores were significantly higher in the acne group than in the control group (p=0.01 and p=0.003, respectively), the invasive tear film breakup time and Schirmer measurements were significantly lower in the acne group (p=0.000 and p=0.003, respectively). The total eyelid and meibomian gland secretion scores were also higher in the acne group than in the control group (p=0.003 and p=0.000, respectively). On the morphological evaluation of the meibomian glands, the thickening, thinning, tortuosity, and presence of ghost areas were statistically significantly more common in the acne vulgaris group than in the control group (p=0.000, p=0.001, p=0.05, and p=0.006, respectively). The percentage of the meibomian gland loss area was significantly high in the acne vulgaris group on both upper and lower meibography. The meibomian gland loss area positively correlated with total eyelid and meibomian gland secretion scores. Conclusion: Acne vulgaris may have a predisposition to meibomian gland dysfunction and ocular surface damage. Early recognition of meibomian gland and ocular surface alterations seems important, especially in acne vulgaris cases for which oral isotretinoin treatment is planned.

RESUMO Objetivo: Todos os indivíduos responderam ao questionário Ocular Surface Disease Index (OSDI) e tiveram avaliados o tempo de ruptura do filme lacrimal pelo método invasivo, a coloração da superfície ocular com fluoresceína e o teste de Schirmer II. Foram ainda avaliados o escore palpebral total e o de secreção das glândulas meibomianas. Foi realizada meibografia sem contato com um dispositivo topográfico corneano Sirius. Métodos: Todos os indivíduos responderam ao questionário Ocular Surface Disease Index (OSDI) e tiveram avaliados o tempo de ruptura do filme lacrimal pelo método invasivo, a coloração da superfície ocular com fluoresceína e o teste de Schirmer II. Foram ainda avaliados o escore palpebral total e o de secreção das glândulas meibomianas. Foi realizada meibografia sem contato com um dispositivo topográfico corneano Sirius. Resultados: Foram incluídos no estudo os olhos direitos de 35 voluntários com acne vulgar e 35 saudáveis. Os escores do Ocular Surface Disease Index e da coloração foram significativamente maiores no grupo com acne em comparação com o grupo controle (p=0,01 e p=0,003, respectivamente), mas o tempo de ruptura do filme lacrimal pelo método invasivo e as medidas do teste de Schirmer II foram significativamente menores (p=0,000 e p=0,003, respectivamente). O escore palpebral total e o escore de secreção das glândulas meibomianas também foram maiores no grupo com acne que no grupo controle (p=0,003 e p=0,000). Na avaliação morfológica das glândulas meibomianas, o espessamento, o afinamento, a tortuosidade e a presença de áreas fantasmas nas glândulas foram mais comuns no grupo acne vulgar que no grupo controle, com significância estatística (p=0,000, p=0,001, p=0,05 e p=0,006 respectivamente). A porcentagem da área de perdas das glândulas meibomianas foi significativamente mais alta no grupo com acne vulgar, tanto na meibografia superior quanto na inferior. A área de perda das glândulas meibomianas demonstrou uma correlação positiva com o escore palpebral total e com o escore de secreção das glândulas meibomianas. Conclusão: A acne vulgar pode levar a uma predisposição para a disfunção das glândulas meibomianas e para danos na superfície ocular. Parece ser importante reconhecer precocemente as alterações das glândulas meibomianas e da superfície ocular, especialmente nos casos de acne vulgar para os quais se planeja o tratamento oral com isotretinoína.

Evaluation of post-operative dry eye in upper and lower eyelid reconstruction: A cross-sectional study

Purpose: In cases of eyelid malignancies requiring full thickness excisional biopsy followed by reconstruction of the created defect, the Meibomian glands are lost. Post?operative varying degrees of dry eye disease (DED) are expected in such patients. The aim was to evaluate the objective and subjective statuses of DED in cases of full thickness eyelid reconstruction following excisional biopsy because of malignancies. Methods: This was a cross?sectional pilot study. Objective and subjective dry eye parameters are assessed in cases of full thickness eyelid reconstruction following excisional biopsy because of malignancies in 37 eyes at 6 months post?operative follow?up. Analysis of variance and Chi square test were used for statistical analysis. Results: When compared with fellow eye, all the parameters were found to be statistically significant (P < 0.0). Subjective assessment of dry eye by ocular surface disease index (OSDI) scoring did not corroborate with the objective data (p 0.00). Lower eyelid reconstruction showed a minimum number of dry eye cases (P > 0.05). Conclusion: Prevalence of post?operative dry eye is more with increasing percentage of full thickness upper eyelid reconstruction. Disparity was found between objective and subjective parameters of dry eye in patients requiring varying percentages of upper eyelid reconstruction because of malignancies.

Double transposition flap for lower eyelid reconstruction: case report of a new surgical approach / Retalho de dupla transposição para reconstrução de pálpebra inferior: relato de caso de uma nova abordagem cirúrgica

Introduction: Non-melanoma tumors frequently affect the lower palpebral region and constitute a challenge for reconstructing the surgical wound without causing functional or aesthetic changes. Primary closure is generally impossible, and flaps are preferred over grafts as they generate less eyelid retraction. This article aims to describe a new surgical reconstruction technique. Method: A modified McGregor flap technique is described for correcting a surgical defect greater than 50% of the anterior lamella of a recurrent basal cell carcinoma lesion in the lower eyelid. Results: The patient was evaluated on the 7th, 14th, 21st, and 45th postoperative days. She presented a good functional and aesthetic response to the technique used. Conclusion: Using the double transposition flap, we demonstrate a new technique for closing defects larger than two-thirds in the lower eyelid.

Introdução: Os tumores não melanomas acometem frequentemente a região palpebral inferior e consistem em um desafio para a reconstrução da ferida operatória sem ocasionar alteração funcional ou estética. O fechamento primário geralmente não é possível e os retalhos são preferenciais aos enxertos por gerarem menor retração palpebral. Este artigo tem como objetivo descrever uma nova técnica de reconstrução cirúrgica. Método: Descreve-se técnica modificada do retalho de McGregor para correção de defeito cirúrgico maior que 50% da lamela anterior, de lesão recidivada de carcinoma basocelular localizada em pálpebra inferior. Resultados: Paciente foi avaliada no 7º, 14º, 21º e 45º dia de pós-operatório. Apresentou boa resposta funcional e estética com a técnica utilizada. Conclusão: Demonstramos uma nova técnica de fechamento de defeitos maiores do que dois terços na pálpebra inferior através do retalho de dupla transposição.

Lupus Vulgaris Coexisting with Sinonasal Tuberculosis and Tuberculous Dacrocystitis.

We describe the case of a 72-year-old female diabetic who presented with epiphora and purulent discharge from the right eye for the past 2 years and multiple skin lesions over the right upper eyelid and right arm for 1 year. Computed tomography of the paranasal sinuses revealed mucosal thickening in the frontal and ethmoidal sinuses, with a polypoidal mass from the right side of the nasal septum and dacrocystitis. The histopathology of the skin lesion was suggestive of lupus vulgaris (LV). There was no evidence of pulmonary tuberculosis. This case was a rare coexistence of LV with sinonasal tuberculosis and dacrocystitis.

Reconstrucción palpebral luego de una resección total por cáncer / Palpebral reconstruction after total resection due to cancer

Introducción: La incidencia de los tumores malignos palpebrales varía según las diferentes razas. Su frecuencia aumenta con la edad y su aparición está relacionada con factores genéticos, virales y ambientales. Objetivo: Presentar un caso con una lesión tumoral en el párpado inferior al que se le realizó la reconstrucción palpebral luego de una resección parcial por cáncer con técnica combinada que incluyó Mustardé e injerto de mucosa. Presentación de caso: Paciente masculino de 76 años de edad con antecedentes de salud. Hace un año atrás comenzó a presentar una lesión endurada en el párpado inferior izquierdo hacia el canto interno del ojo, que fue aumentando de volumen, con una ulceración posterior. En el examen físico se observó una lesión ulcerada y sucia de aproximadamente 2 ( 2,5 cm, que comprometía los 2/3 mediales del parpado inferior, incluyendo la vía conducto lagrimal. Tras la intervención quirúrgica la extirpación creó un defecto correspondiente a la ausencia en todos los planos anatómicos en casi la totalidad del párpado inferior izquierdo, por lo que se planeó un colgajo de avance de la mejilla. El estudio histopatológico confirmó un carcinoma epidermoide completamente resecado. Conclusiones: Esta cirugía combinada permitió una exéresis amplia del tumor con el margen oncológico requerido y la sustitución aproximada de las estructuras del párpado. Se lograron una funcionabilidad adecuada y una cubierta del globo ocular óptima en su porción inferior, además de armónico con el contralateral(AU)

Introduction: The incidence of palpebral malignant tumors varies according to different races. Its frequency increases with age and its occurrence is related to genetic, viral and environmental factors. Objective: To present a case with a tumor lesion in the lower eyelid, who underwent palpebral reconstruction after a partial resection due to cancer with a combined technique including Mustardé and mucosal graft and its clinical evolution. Case presentation: 76-year-old male patient with a medical history. One year ago he began to present an indurated lesion on the left lower eyelid towards the inner canthus of the eye that was increasing in volume, with subsequent ulceration. Physical examination revealed an ulcerated and dirty lesion of approximately 2 ( 2.5 cm involving the medial 2/3 of the lower eyelid, including the lacrimal duct. After surgery the excision created a defect corresponding to the absence in all anatomic planes in almost the entire left lower eyelid, so a cheek advancement flap was planned. Histopathologic study confirmed a completely resected epidermoid carcinoma. Conclusions: This combined surgery allowed wide excision of the tumor with the required oncologic margin and approximate replacement of the eyelid structures. Adequate functionality and optimal eyeball cover was achieved in its lower portion, as well as harmonic with the contralateral one(AU)

Relationship between actinic keratosis and malignant skin lesions on the eyelid / Relação entre ceratose actínica e lesões cutâneas malignas na pálpebra

ABSTRACT Purpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.

RESUMO Objetivo: Avaliar as possíveis variáveis relacionadas à ceratose actínica e lesões malignas cutâneas nas pálpebras. Métodos: Estudo prospectivo de pacientes com lesões palpebrais suspeitas de malignidade. Os participantes foram submetidos à biopsia por trépano (punch) de 2-mm em dois pontos opostos da lesão como método diagnóstico e os resultados foram comparados com o estudo histopatológico da peça excisada cirurgicamente. Aqueles que apresentaram ceratose actínica como resultado foram divididos em dois grupos (ceratose actínica associada com malignidade e ceratose actínica isolada) e foram comparados de acordo com as variáveis: idade, tempo de doença, maior diâmetro, área do tumor, classificação de Fitzpatrick, gênero, localização e acometimento da margem palpebral. A análise de cluster também foi realizada. Resultados: Foram analisadas 174 lesões e 50 delas tinham ceratose actínica como componente do tumor. Ceratose actínica esteve associada ao Carcinoma Espinocelular em 22% dos casos e ao Carcinoma Basocelular em 38%, mostrando que ambos podem ter ceratose actínica adjacente. A análise estatística não encontrou diferença entre as variáveis. A análise de cluster identificou quatro grupos e mostrou que lesões malignas no canto medial tinham maiores diâmetro e área. Acometimento da margem na pálpebra inferior relacionou-se em 100% com malignidade, enquanto a ausência de acometimento da margem mostrou menor chance de malignidade. Conclusões: Lesões maiores de ceratose actínica no canto medial e lesões com acometimento da margem palpebral inferior têm maiores chances de associação com malignidade.

Research progress on the relationship between lid-wiper epitheliopathy and dry eye / 国际眼科杂志(Guoji Yanke Zazhi)

Lid-wiper epitheliopathy(LWE)refers to the corresponding pathological changes in the palpebral conjunctiva after the skin-mucosa junction area of the palpebral margin, and staining occurs after using dyes such as fluorescein sodium or lissamine green. Current studies suggest that LWE mainly results from the increase of friction between the lid wiper and the ocular surface. The specific mechanism of LWE is not clear, but the common causes include wearing contact lenses, abnormal tear film, blink abnormalities and inflammation. Clinical studies have found that LWE appears when the conventional dry eye index is negative, so the diagnosis of LWE plays an important role in the early diagnosis and treatment of dry eye. However, there are few studies on the correlation between LWE and dry eye in clinical practice. Based on the existing clinical studies, the etiology, pathogenesis, clinical manifestations and treatment of LWE are introduced, and the research progress of LWE and dry eye is reviewed, hoping to provide reference for further investigation and the clinical application of LWE.

Imbalance between myopic shift and the minimum amplitude of accommodation: a hypothesis for the pathogenesis of ocular hypertension secondary to drug-induced bilateral acute ciliochoroidal effusion / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To report 5 cases with drug-induced bilateral acute ciliochoroidal effusion(DBACE)and myopic shift, with or without ocular hypertension(OHT), summarize patients' clinical characteristics and recovery process of DBACE, and investigate the possible pathophysiological mechanism.METHODS:A retrospective observational case study conducted from June 2017 to February 2021. The included patients were subjected to a series of ocular examinations listed as follows: 1)best corrected visual acuity; 2)intraocular pressure(IOP); 3)slit-lamp microscopy; 4)fundus photography; 5)ultrasound biomicroscopy(UBM); 6)subjective optometry; 7)axial length and anterior chamber depth. All patients were followed up every 2d until the diopters were completely restored to the state before the disease onset.RESULTS:In total, 5 patients aged 10-45 years old, including 3 female and 2 male patients, were enrolled in this study. All patients were bilaterally involved(5/5), and had myopic shift(5/5), of whom 3 patients had OHT(3/5). With the increase of age, myopic shift decreased, while OHT increased. Based on OHT, the dynamic aggravation process of DBACE was subdivided into 2 stages, stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). With the deterioration of DBACE, when myopic shift approached or exceeded the minimum amplitude of accommodation(MAA), IOP gradually rose, and DBACE progressed from stage 1 to stage 2. With the recovery of DBACE after discontinuing the suspicious drugs, DBACE in stage 2 first returned to stage 1, and then returned to normal.CONCLUSION:Pathophysiological mechanism of DBACE was subdivided into 2 stages, including stage 1(myopic shift without OHT)and stage 2(myopic shift with OHT). The transition between the two stages depends on the imbalance between myopic shift and MAA.

Correction of the first and second degree of upper eyelid depression with orbital septal fat anatomic reduction in blepharoplasty / 中华医学美学美容杂志

Objective:To investigate the method and effect of anatomic reduction of orbital septum fat in blepharoplasty to correct the first and second degree of upper eyelid depression.Methods:From January 2019 to January 2021, the data of patients with first and second degree upper eyelid depression admitted to Beijing Anzhen Hospital, Capital Medical University were retrospectively analyzed. Orbital septum was fully exposed and cut in blepharoplasty, the orbital fat of upper eyelid central group and the medial group were dissected and seperated to form the fat flap pedicled on the medial side. The fat flap was rotated 180° to the medial side and fixed with the orbital fat of the medial group to correct the upper eyelid depression. Complications such as infection, hematoma, fat liquefaction, nodules and orthers were observed after surgery. Questionnaire was used to investigate the satisfaction of patients, with 1-4 points indicating dissatisfaction, general satisfaction, satisfaction and very satisfaction, respectively.Results:A total of 62 patients were included, all patients were female, aged 18-44 years, wit mean 27 years. All patients were bilateral upper eyelid depression. After 6 months of follow-up, the curvature of the double eyelid line was smooth, the width and narrowness of double eyelid were natural, and the upper eyelid depression was significantly improved. Satisfaction survey showed that 60 cases were very satisfied and 2 cases were satisfied. Wound infection was occurred in 1 case, and was cured after dressing change. Scar hyperplasia was observed in 2 cases, which was obviously alleviated after external treatment with anti-scar hyperplasia drugs. No fat liquefaction, nodule and other complications occured.Conclusions:For the first and second degree of upper eyelid depression, it can be corrected by anatomic reduction of orbital septal fat in blepharoplasty. The operation is simple, with fewer complication and high satisfaction.

Influence of exophthalmos on design of double eyelid incision / 中华医学美学美容杂志

Objective:To compare the postoperative effects of double eyelid surgery with different exophthalmos to find its influence on the surgery and necessary changes in preoperative design and during operation.Methods:A total of 50 female patients with single eyelid seeking beauty from June 2021 to March 2022 were selected from the Department of Plastic Surgery, Affiliated Hospital of Qingdao University. The ocular protrusion was measured by HETEL ophthalmostatometer before surgery. Both eyes at 12-15 mm were taken as normal group ( n=26), both eyes at 16-18 mm as mild protrusion group ( n=14) and both eyes at 19-22 mm as severe protrusion group ( n=10). All the patients were treated with double-eyelid surgery by orbital septum and unified postoperative nursing. Results:After six months of follow-up, there was no difference in eyelid width with closed eyes (all P>0.05). The width of double eyelid with open eyes in normal group was smaller than that in mild protrusion group ( F=23.23, all P<0.05), and the width of double eyelid with open eyes in mild protrusion group was smaller than that in severe protrusion group ( F=47.70, all P<0.05). There was no difference in the improvement rate of facial aesthetics among the three groups ( P>0.05). The " feeling of meet" and scar formation in the normal group were less than those in the mild protrusion group ( F=16.92, F=33.45, all P<0.05), and the " feeling of meet" and scar formation in the mild protrusion group were less than those in the severe protrusion group ( F=27.93, F=28.53, all P<0.05). The improvement rate of normal group was higher than that of mild and severe protrusion group (χ 2=7.25, 7.89, all P<0.05). There was no difference in the improvement rate between the mild and severe protrusion groups ( P>0.05). Conclusions:In clinical practice, it is necessary to make corresponding changes in the preoperative design and operation of double eyelid surgery for patients with high eyeball protrusion.

Clinical application of botulinum toxin type A in the treatment of thyroid-associated ophthalmopathy / 国际眼科杂志(Guoji Yanke Zazhi)

Thyroid-associated ophthalmopathy(TAO)is an autoimmune inflammatory disease involving multiple orbital tissues with a variety of clinical manifestations, which has serious effects on the life quality of patients.Interventions of TAO mainly include medical treatment to stabilize thyroid function, reduce inflammation and regulate immune function, as well as surgical treatment to relieve ocular symptoms. Botulinum toxin type A can paralyze muscles by blocking nerve impulse conduction at the neuromuscular junction, which is of certain therapeutic value for restrictive strabismus due to extraocular muscle involvement and upper eyelid retraction due to involvements of levator palpebrae superioris and Müller's muscle in TAO patients, especially when they have surgical contraindications, lack surgical opportunity, or refuse surgery. This paper reviews the application of botulinum toxin type A in the treatment of TAO, focusing on its pharmacological mechanism, dosage, effectiveness, and possible complications when treating restrictive strabismus and upper eyelid retraction, and discussing potential therapeutic values of botulinum toxin type A for intraocular pressure elevation, glabellar frown lines and dry eye caused by extraocular muscle compression in TAO patients, in order to provide a reference for clinical intervention.

Research progress of iatrogenic blepharoptosis repair after double eyelid surgery / 中国修复重建外科杂志

OBJECTIVE@#To summarize the etiology mechanism and treatment of iatrogenic blepharoptosis after double eyelid surgery in Asia.@*METHODS@#To extensively review the literature related to iatrogenic blepharoptosis after double eyelid surgery, and to summarize and analyze the related anatomical mechanism, existing treatment options, and indications.@*RESULTS@#Iatrogenic blepharoptosis is a relatively common complication after double eyelid surgery, sometimes it is combined with other eyelid deformities such as sunken upper eyelid and wide double eyelid, which makes it difficult to repair. The etiology is mainly caused by improper adhesion of tissues and scars, improper removal of upper eyelid tissue, and injury of a link of levator muscle power system. Whether blepharoptosis occurs after double eyelid surgery by incision or suture, it should be repaired by incision. The principles of repair include surgical loosening of tissue adhesion, anatomical reduction, and repair of damaged tissues. The key is to use surrounding tissues or transplanted fat to prevent adhesion.@*CONCLUSION@#When repairing iatrogenic blepharoptosis clinically, appropriate surgical methods should be selected based on the causes and severity of the blepharoptosis, combined with treatment principles, in order to achieve better repair results.
