RESUMEN
BACKGROUND: Angiosarcoma is an extremely rare malignant tumor. So far, only about 42 cases of angiosarcoma involving the eyelids have been reported. Eyelid angiosarcoma occurs more frequently in elderly Caucasian males and is prone to misdiagnosis. We present a case report in a young Asian male patient with eyelid angiosarcoma that was misdiagnosed as a chalazion. CASE PRESENTATION: A 46-year-old South Korean male with no underlying disease had a right lower lid mass. The lesion was initially misdiagnosed as a chalazion at a local clinic, but a diagnosis of eyelid angiosarcoma was made after the first biopsy trial. PET-CT was performed to ensure that there was no metastasis in the whole body. Surgical excision with enough surgical margin was used alone for treatment and reconstruction was performed with a tarsoconjunctival advancement flap (modified Hughes procedure), which helped ensure good cosmesis. No recurrence was observed 4 years and 5 months after the surgery. CONCLUSIONS: The current study presents the first case of chalazion-mimicked eyelid angiosarcoma in a young Asian male aged under 50 years. This case shows that even if a benign eyelid disease is suspected in a young patient, an incisional biopsy must be performed to confirm whether the lesion is malignant. Since the prognosis is good for the case of eyelid angiosarcoma, if there is no clear evidence of distal metastasis, surgical resection should be performed with an enough safety margin.

PURPOSE: To report the clinical features, treatment, and outcome of 11 patients with orbital schwannoma in Korean patients. METHODS: The medical records of 11 orbital schwannoma patients treated between April 2007 and April 2021 were retrospectively reviewed. The demographic data, clinical characteristics, radiological features, and outcomes were reviewed. RESULTS: The mean age at the time of diagnosis was 49.00 ± 14.45 years. The most common initial symptom was ocular protrusion (n = 7), and other symptoms were decreased visual acuity ( n = 5), restriction of eye movement ( n = 4), swelling ( n = 3), and pain ( n = 2). Locations of tumors were superomedial; followed by the orbital apex and inferolateral. The most common shape seen in our patients was beads like multilobulated appearance; followed by a round, oval, fusiform, and dumbbell shape. MRI of T1-weighted revealed isointense or hypointense, whereas the T2-weighted indicated hyper or isointense lesion. Five patients had optic neuropathy at presentation, and 1 of them showed improved vision after surgery. Complete or incomplete excision was performed for all. Surgical complications include decreased vision and paraesthesia. There has been no recurrence to date. CONCLUSIONS: Orbital schwannoma is a rare disease and it is difficult to distinguish it from other orbital tumors because the initial symptoms are nonspecific. Differential diagnosis by combining the shape, location, and contrast enhancement findings seen on computed tomography and magnetic resonance imaging can be helpful in surgical treatment. Complete excision gives the best results without recurrence, but if the patient is in an inaccessible location, only surgery to reduce the volume can satisfy the patient without recurrence.

OBJECTIVE: To report the clinical features of 20 patients with malignant melanoma and to evaluate the survival and prognosis of patients with malignant melanoma in Korea. METHODS AND ANALYSIS: The medical records of 20 patients with malignant melanoma treated between March 2004 and March 2020 were reviewed retrospectively. The demographic data, clinical characteristics, and outcomes were also reviewed. Outcome measures included local recurrence, metastasis, and tumor-related mortality. Prognostic factors associated with recurrence, metastasis, and survival were analyzed using a Cox proportional hazards model. RESULTS: Among the 20 patients with periocular malignant melanoma, 4 (20%) showed local recurrence during follow-up (6.61â±â6.36 years). The 1-, 5-, and 10-year recurrence rates were 5%, 10.3%, and 24.1%, respectively. 10 (50%) patients developed distant metastasis, mainly involving lung, brain, parotid gland and spine. The 1-, 5-, and 10-year rates of metastasis were 5%, 10.9%, and 35.7%, respectively. Significantly fewer metastases were detected following initial extensive surgical excision (Pâ=â0.04). 8 (40%) patients died of malignant melanoma. The main risk factor for mortality was tumor thickness (HR: 3.88, Pâ<â0.01). Based on Kaplan-Meier survival estimates, the 1-, 5-, and 10-year tumor-related survival rates were 75.8%, 55.6%, and 55.6%, respectively. CONCLUSION: Tumor thickness is a significant prognostic factor affecting the survival rate. It is important to reduce the metastatic rate via extensive resection without leaving any residual tumor in the margin during surgery.

BACKGROUND: The purpose of this study is to analyze and classify morphological features of the nasolacrimal duct (NLD) through 3D reconstruction to help understand the causes and treatment of NLD obstruction. METHODS: In this study, we included 63 males and 55 females who underwent autopsy without NLD obstruction with ages ranging from 20 to 78 years. The NLD was defined from the lacrimal fossa to the opening of the BNLD to the inferior meatus, and all continuous CT images showing the NLD were selected. Segmentation was performed semi-automatically, and the reconstruction and measurement of NLD was performed using the Mimics program. RESULTS: Overall NLD length, bony nasolacrimal duct (BNLD) length, anteroposterior and transverse diameters at the entrance to the BNLD, anteroposterior and transverse smallest diameters of the BNLD, BNLD volume, and lacrimal sac BNLD angle were significantly higher in males than females (p < .05). BNLD direction in the coronal plane was slightly more likely to be inward. The most common type in both sexes was cylinder type (42.0%), males were more likely to have lower-thicker types (34.1%), and females more likely to have upper-thicker types (22.7%). CONCLUSION: There were sex differences in NLD measurements, and females had significantly smaller NLDs. These results may partially explain the increased prevalence of primary acquired NLD obstruction in females. The BNLD tends toward the midline, and inclines posteriorly.

Exosomes contain proteins, lipids, RNA, and DNA that mediate intercellular signaling. Exosomes can contribute to the pathological processes of various diseases, although their roles in ocular diseases are unclear. We aimed to isolate exosomes from tear fluids (TF) of patients with Thyroid eye disease (TED) and analyze the exosomal proteins. TFs were collected from eight patients with TED and eight control subjects. The number of TF exosomes were measured using nanoparticle-tracking analysis. The expression of specific proteins in the purified exosome pellets were analyzed using a Proteome Profiler Array Kit. Cultured normal orbital fibroblasts were incubated with TF exosomes from patients with TED and control subjects, and changes in inflammatory cytokine levels were compared. TF exosomes from TED patients showed more exosomes than the control subjects. The expression levels of exosomal proteins vitamin D-binding (VDB) protein, C-reactive protein (CRP), chitinase 3-like 1 (CHI3L1), matrix metalloproteinase-9 (MMP-9), and vascular adhesion molecule-1 (VCAM-1) were significantly increased in patients with TED, compared to those of controls. Orbital fibroblasts exposed to TF exosomes from patients with TED showed significantly higher levels of interleukin (IL)-6, IL-8, and monocyte chemoattractant protein-1 (MCP-1) production than those treated with control TF exosomes. Specific proteins showed higher expression in exosomes from TED patients, implying that they may play keys roles in TED pathogenesis.

BACKGROUND: Radiation therapy (RT) is the treatment of choice in patients with low-grade ocular adenexal mucosa-associated lymphoid tissue lymphoma (OAML) and many of them experience post-RT dry eye with varying severity. The purpose of the present study was to investigate ocular effects of RT on meibomian glands and dry eye by directly visualizing structural changes. Secondly, we focused on the comparison of two groups of patients according to tumor location and radiation technique. METHODS: Sixty-four eyes with OAML of conjunctiva, orbit, lacrimal gland, or lacrimal sac were grouped into conjunctival lymphoma and "orbital-type" lymphoma (i.e., orbit, lacrimal gland, and lacrimal sac). Subjects were investigated for morphological changes in meibomian glands by meiboscore grading system. Radiation technique was examined and Ocular Surface Disease Index (OSDI) questionnaire, Schirmer's test, tear film break-up time (TBUT), slit lamp examination of corneal surface and lid margin abnormality were conducted before and after RT. RESULTS: The increase in meiboscore was statistically significant over time after RT in both groups (P < 0.001). The extent of increase in meiboscore was significantly greater in the "orbital-type" lymphoma group than in the conjunctival lymphoma group (P < 0.001). The changes in OSDI, TBUT, corneal fluorescein staining score and lid margin abnormality score after RT were significantly different across two groups (P = 0.042, 0.001, 0.035 and 0.001, respectively). Schirmer's value decreased after RT in both groups. Dry eye symptoms were most severe right after RT in both groups, but a gradual resolution was noted in most patients with conjunctival lymphoma, whereas symptoms persisted in "orbital-type" lymphoma patients. The OSDI score and corneal fluorescein staining score were positively correlated with meiboscore in "orbital-type" patients at post-RT 6 months (r = 0.43, P = 0.04; r = 0.39, P = 0.03, respectively). CONCLUSIONS: Patients with OAML had different degrees of morphological changes in meibomian glands according to tumor location and radiation technique. "Orbital-type" lymphoma patients are more likely to experience severe injury to meibomian glands, which eventually leads to persistent dry eye. Patients with "orbital-type" lymphoma should be well informed of post-RT damage on meibomian glands and persistent dry eye.

BACKGROUND: To evaluate the prevalence of blepharoptosis among Korean adults and the characteristics of blepharoptosis patients, and to determine an appropriate age threshold for recommending blepharoptosis evaluation. METHODS: The Korean National Health and Nutrition Examination Survey (KNHANES-V) was conducted in 2010-2012. We extracted data on 17,878 Korean adults aged more than and equal to 19 years included in KNHANES-V, and determined blepharoptosis prevalence according to age, to determine the cutoff age for recommending blepharoptosis evaluation. We also determined the possible association between blepharoptosis and obesity parameters, such as body mass index (BMI) and waist circumference (WC). RESULTS: There was astrong association between older age and the prevalence of blepharoptosis. The cutoff age for recommending blepharoptosis evaluation was 63 years for males, 70 years for females, and 66 years for all patients. Patients with a high BMI and large WC had a higher prevalence of blepharoptosis in all age groups except for those aged over 80 years. The association of blepharoptosis with BMI according to age group showed that in the 50-59 and 60-69 years age groups, blepharoptosis prevalence and BMI were higher. However, in the 70-79 and 80-89 years age groups, extremely obese patients (BMI > 30) showed a decreased blepharoptosis prevalence. CONCLUSIONS: Moderate to severe blepharoptosis can result in poor visual function and exacerbate headaches and depression, leading to decreased quality of life. This study proposed an appropriate age threshold for recommending evaluation of patients with blepharoptosis among the general population of Korea.

Tumor metastasis to the eyelids is very rare. The authors report the first case of a neuroendocrine tumor that originated from the ampulla of Vater in the gastrointestinal tract and metastasized to the eyelid. The patient with a hospice care was referred to the authors' eye clinic after presenting with a palpable mass on the left eyelid and blinking discomfort. He was previously diagnosed with a neuroendocrine tumor arising from the ampulla of Vater. The eyelid tumor was simply removed to relieve discomfort, and histological and immunophenotypic evaluation of the resected eyelid mass showed a poorly differentiated neuroendocrine tumor with large cell types, similar to specimens from the duodenum.

A liposarcoma of the orbit is extremely rare and a metastatic liposarcoma of the orbit is even rarer. Histologically, metastatic tumors frequently resemble the appearance of the primary lesion or may be less differentiated. In the present paper, we report on a case of a metastatic liposarcoma of the orbit and brain in which dedifferentiated transformation occurred from the primary tumor. The primary liposarcoma was a myxoid liposarcoma in the thigh, which had been resected 6 years ago. The metastatic orbital liposarcoma was poorly differentiated compared to the primary tumor and the tumor in the brain was even more poorly differentiated and anaplastic than the tumor in orbit. The tumor in the orbit and brain was completely removed and postoperative radiotherapy and chemotherapy were performed.

BACKGROUND: To demonstrate that the Corvis ST could be used to quantify the biomechanical parameters of the orbital soft tissues by measuring and comparing whole eye movement (WEM) using the Corvis in normal eyes and in eyes of patients with Graves ophthalmopathy. METHODS: Forty four eyes of 44 ophthalmologically normal subjects and 28 eyes of 28 patients with Graves ophthalmopathy were included in the study. After Corvis test, the examiners recorded WEM by air puff. In the patients with Graves ophthalmopathy, the partial correlation coefficient adjusted for age and gender was calculated to analyze the correlation between exopthalmometry and WEM. Same analysis was repeated for the correlation between and the cross sectional area (%) of the extraocular muscles in the orbit CT and WEM. RESULTS: WEM was 0.314 ± 0.083 mm in the normal subjects and 0.227 ± 0.079 mm in the Graves ophthalmopathy group (p = 0.000). The exophthalmometry was not significantly correlated with WEM after adjusting for age and gender (R = 0.083, p = 0.688). In the 21 Graves ophthalmopathy patients examined by orbit CT, after adjusting for age and gender, WEM significantly decreased as the cross sectional area (%) of the extraocular muscles in the orbit increased (R = - 0.461, p = 0.047). CONCLUSIONS: WEM by Corvis could be used to quantify the biomechanical parameters of the orbital soft tissue. However, it is unclear whether WEM effectively represents the orbital biomechanical parameters, because WEM is only 0.6% of the orbital depth.

The present study evaluated the surgical outcomes of intraconal cavernous venous malformation according to their location in 4 right-angled sectors. Data regarding the surgical method and approach, surgical outcome, and postoperative complications were retrospectively analyzed for 18 patients with intraconal cavernous venous malformations that were surgically treated at the authors' center between March 2006 and May 2017. The lesion location was defined using 2 perpendicular lines connecting the optic disc and the 4 surrounding rectus muscles in the coronal plane, which resulted in the formation of 4 right-angled sectors (upper-outer quadrant, upper-inner quadrant, lower-inner quadrant, and lower-outer quadrant). Accordingly, there were 3, 3, 8, and 4 lesions in the upper-outer, upper-inner, lower-outer, and lower-inner quadrants, respectively. Ten patients received anterior orbitotomy and 8 received lateral orbitotomy. There were no recurrences during the follow-up period. All patients exhibited reduced proptosis after surgery. Vision improved in 4 patients and remained unchanged in 14. Five patients experienced ocular movement limitation (1 permanent and 4 temporary), 1 developed an inferomedial blowout fracture, 2 developed a temporary sensory deficit, and 1 developed temporary ptosis. The authors' findings suggest that intraconal cavernous venous malformations most frequently occur in the lower-outer quadrant. Although most lesions can be removed via anterior orbitotomy, large lesions located near the orbital apex or on the orbital wall require lateral orbitotomy. Ocular movement limitation is a common complication and can become permanent in rare cases, necessitating close monitoring. Lesion location and surgical approach do not seem to influence the postoperative complication rate.

PURPOSE: To report long-term surgical outcomes of Cutler-Beard reconstructive surgery in patients with large full-thickness upper eyelid defects following malignant tumor excision. METHODS: The medical records of 5 consecutive patients with full-thickness upper eyelid defects following tumor resection who underwent Cutler-Beard surgery were reviewed retrospectively between April 2005 and November 2018. Surgical procedure comprises 2 stages: first, complete tumor resection followed by bridged full-thickness lower eyelid advancement flap; second, separation of the closed eyelid with eyelid margin repair 7 to 9 weeks later. Postoperative anatomical, functional and cosmetic outcomes, and complications were evaluated during follow-up at 22 to 77 months. RESULTS: Patients were in the age group of 49 to 75 years, including 3 (60%) females and 2 (40%) males. Three of the 5 patients (60%) exhibited sebaceous cell carcinoma and 2 (40%) showed squamous cell carcinoma. Three patients (60%) underwent Cutler-Beard surgery after recurrence of primary carcinoma following previous operation. Three patients underwent revision surgery with entropion, 2 underwent correction for wound dehiscence and 1 was treated with symblepharon lysis. No serious or permanent ocular complications were observed during the operation or follow-up with the patients. The procedure resulted in good aesthetic quality and acceptable sequelae at the donor site. CONCLUSIONS: Cutler-Beard procedure for the reconstruction of large and full-thickness upper eyelid defects is an effective procedure with satisfactory long-term results, although a few patients may require minor revision surgery.

The evaluation of morphological changes of the acini in the meibomian glands is important for the diagnosis and management of dry eye related to meibomian gland dysfunction. While several tools have been developed to detect meibomian gland structure, infrared imaging is generally used in clinical settings. Unlike the lipid component analysis of tear film in which quantitative analysis is possible, the meibomian glands are limited to qualitative analysis because of the low image quality of the diagnostic tools. This review describes diagnostic tools, especially in terms of morphological evaluation of the acini, which are visualized by the existence of lipid within them.

BACKGROUND: To report six cases of CD34+ fibroblastic mesenchymal tumours, which are uncommon neoplasms in the orbit. CASE PRESENTATION: Six patients presenting with proptosis and palpable mass who were later diagnosed with fibrous solitary tumours, fibrous histocytoma or haemangiopericytoma in the orbit were included. All patients received radiologic examinations and surgical excision for histopathology and immunohistochemistry examinations. Five patients had no recurrence after a minimum follow-up of 12 months. One patient (case 6) experienced recurrence twice, and had debulking surgeries each time. At present, the patient still has remnant tumour in the orbit, but no growth has been detected during the past two years. The tumour size will be closely monitored. CONCLUSIONS: Even though fibroblastic tumours are rarely found in the orbit, they can present as a palpable mass with proptosis. Complete surgical excision is important for long-term prognosis, and immunohistochemical study is helpful for confirming pathologic diagnosis.

BACKGROUND: Cyclic strabismus is a very rare condition of ocular motility characterized by alternating strabismus and orthotropia. We report a patient with a 48-h cycle of vertical deviation associated with dysthyroid ophthalmopathy that spontaneously resolved. CASE PRESENTATION: A 40-year-old woman experienced sudden onset vertical double vision. She had already been diagnosed with hyperthyroidism. Asymmetric enlargement of the inferior and medial rectus muscles was demonstrated in her left eye on computed tomography, and was compatible with dysthyroid ophthalmopathy. She clearly described the "every-other-day" pattern of diplopia that spontaneously switched around 8 o'clock every night. She exhibited left hypotropia of 35 prism diopters on a bad day, and 7 prism diopters on a good day. CONCLUSIONS: This case illustrates that cyclic vertical deviation may spontaneously resolve along with the course of the underlying diseases that initiated the cyclic deviation, especially in patients with conditions involving motor component changes such as dysthyroid ophthalmopathy.

BACKGROUND: We examined the effect of surgical repair on the pattern of refractive errors in Korean patients with congenital blepharoptosis. METHODS: We reviewed the clinical records of 54 patients with congenital blepharoptosis who attended our hospital from 2006 to 2012 and underwent a detailed refractive examination before and after ptosis repair surgery. Among them, 21 of the patients whose refractive data was available for both before and after the surgery were included in order to observe the effect of ptosis repair surgery on refractive error characteristics. The astigmatism groups were divided into three subgroups: with-the-rule (WTR), against-the-rule (ATR), and oblique astigmatism (OA). We also evaluated the severity of astigmatism. RESULTS: Before surgery, the ptotic eyes had more severe astigmatism and a greater percentage of OA than the fellow eyes. The changes in astigmatism magnitude before and after surgery were not significant, but the proportion of subjects with OA increased significantly. In ptotic eyes, amblyopia was found in 14 eyes (20.9 %). 3 eyes (4.5 %) were from solely occlusive visual stimulus deprivation due to severe ptosis, and 11 eyes were from refractive errors. Among refractive errors, amblyogenic astigmatism made up to the largest proportion of patients (8 patients, 11.9 %). CONCLUSIONS: Ptotic eyes had more severe astigmatism and more OA than fellow eyes. Amblyogenic astigmatism was more common in ptotic eyes. A change in astigmatism toward the OA axis was significantly detected after surgery, and that can be possible amblyogenic cause. Therefore, the correction of astigmatism before and after ptosis repair surgery is very important to prevent amblyopia.

Patients with anophthalmic or phthisis socket suffer from cosmetic problems. To resolve those problems, the authors present the surgical outcomes of deep superior sulcus (DSS) augmentation using acellular dermal matrix in patients with anophthalmic or phthisis socket. The authors retrospectively reviewed anophthalmic or phthisis patients who underwent surgery for DSS augmentation using acellular dermal matrix. To evaluate surgical outcomes, the authors focused on 3 aspects: the possibility of wearing contact prosthesis, the degree of correction of the DSS, and any surgical complications. The degree of correction of DSS was classified as excellent: restoration of superior sulcus enough to remove sunken sulcus shadow; fair: gain of correction effect but sunken shadow remained; or fail: no effect of correction at all. Ten eyes of 10 patients were included. There was a mean 21.3â±â37.1-month period from evisceration or enucleation to the operation for DSS augmentation. All patients could wear contact prosthesis after the operation (100%). The degree of correction was excellent in 8 patients (80%) and fair in 2. Three of 10 (30%) showed complications: eyelid entropion, upper eyelid multiple creases, and spontaneous wound dehiscence followed by inflammation after stitch removal. Uneven skin surface and paresthesia in the forehead area of the affected eye may be observed after surgery. The overall surgical outcomes were favorable, showing an excellent degree of correction of DSS and low surgical complication rates. This procedure is effective for patients who have DSS in the absence or atrophy of the eyeball.

Ocular adnexal mucosa-associated lymphoid tissue lymphoma (OAML) has been recognized as most common primary orbital malignancy. However, little was known about the response criteria for OAML. Our aim was to suggest response criteria for nonconjunctival OAML; the response evaluation of which using the conventional response criteria is inappropriate. A retrospective chart review of 34 eyes from 30 patients diagnosed with nonconjunctival OAML was conducted, focusing on the change in tumor size based on linear bi-dimensional and three-dimensional methods in magnetic resonance imaging (MRI) of the orbit. The maximum tumor response period of each case was investigated, and the expected optimal response period was calculated using regression analysis. In 30 evaluable patients, the median time taken for the maximum tumor response was 6 months (range, 3-18). More than 75 % of patients attained maximal tumor response in 6 months after initial therapy for follow-up period, the median value of which was 30 months (range, 15-77). Based on the regression analysis, it took 4.7 months for the maximum diameter (2r) of tumor to decrease by 50 % of initial lesion size. We cautiously suggest that optimal response could be defined as 50 % reduction of the maximum diameter in 6 months since the treatment was initiated, and that only observation without additional therapy is enough for nonconjunctival OAML, if optimal response is achieved.

PURPOSE: We report the surgical outcomes of acellular human dermal allografts for repair of large conjunctiva defects in primary or secondary orbital implant insertion. METHODS: This retrospective chart review examined 12 eyes in 12 patients who underwent primary or secondary orbital implant insertion using Medpor® and acellular human dermal allografts to decrease conjunctival tension. Only patients with at least 6 months follow-up were included. The procedure was successful if there was no exposure until the last eye-clinic visit and the patient could wear a prosthesis. It failed if additional surgery was needed to correct the orbital implant exposure. RESULTS: The mean follow-up was 24.5 (range 6-54) months. Seven patients had primary orbital implant insertion, and five had secondary orbital implant insertion with acellular human dermal allografts. All enrolled patients had successful outcomes without exposure of the central conjunctiva. Two underwent additional surgery to correct fornix contracture and regain a cosmetically good prosthesis. Of these, one patient received additional acellular human dermal grafts and had a fair outcome. The other patient ultimately required fornix reconstruction with an autologous graft using oral mucosa. CONCLUSION: Orbital implant insertion with acellular human dermis grafts had good surgical outcomes. The procedure could be effective for patients with insufficient conjunctival tissue to cover an orbital implant and a high probability of developing orbital implant exposure if tension was created by excessive direct conjunctival closure.
