A case report of phacolytic glaucoma in lens cortex behind posterior capsule: A CARE-compliant article.

RATIONALE: Phacolytic glaucoma (PLG), a secondary open-angle glaucoma caused by high molecular weight proteins leaking through the capsule of a hypermature cataract. Leakage of liquefied lens cortex behind the posterior capsule is rare. In this paper, we review a case of phacolytic glaucoma in the lens cortex behind posterior capsule. PATIENT CONCERNS: This case report describes a 79-year-old male patient with a 7-year history of progressive blurred vision and a 1-day history of distended in his left eye. He underwent phacoemulsification combined with intraocular lens implantation at our facility 7 years ago. DIAGNOSES: The patient had lower vision (light perception vision) and increased intraocular pressure (IOP) (60 mmHg) in the left eye. Auxiliary inspection found that the left eye had deep anterior chamber depth (around 1 corneal thickness of the peripheral AC angle) as well as vitreous and aqueous humor opacity in the left eye. Combining the clinical symptoms and examinations, we made the diagnosis of PLG in the left eye. INTERVENTIONS: The patient underwent trabeculectomy and extracapsular cataract extraction of the left after a stable ocular condition, during the operation to see that white chyous cortex was visible under the posterior capsule and posterior capsule membrane of the lens was avulsed circularly. OUTCOMES: The postoperative condition was stable. During the follow up of 3 months, the IOP of the left eye was stable without ocular discomfort. LESSONS: This case reported a patient with phacolytic glaucoma in the lens cortex behind posterior capsule who underwent successful surgery, indicating spontaneous capsule rupture can occur in the posterior capsules in PLG and when this situation is detected during the operation, the posterior capsule tearing method can be applied to absorb the lens cortex sticking at the posterior surface of the posterior capsule.

Orbitofrontal cholesterol granuloma masquerading as frontal sinus mucoceles: report of two cases.

BACKGROUND: Two cases of orbitofrontal cholesterol granuloma masquerading as frontal sinus mucoceles were reported to understand image findings, clinical and histopathologic features of orbitofrontal cholesterol granuloma to improve its diagnosis and treatment. CASE PRESENTATION: Two East Asian patients aged 41 and 27 without personal or familial medical or trauma history presented with the common complaint of proptosis and inferomedial displacement of the eyeballs. The computed tomography (CT) of both cases showed an irregularly shaped, well-defined lesion in the left frontal bone associated with bony erosion. The lesions resulted in the bone absorption of frontal bone and orbital roof, which extended into the superior orbital space. Anterior orbitotomy through subbrow incision by drainage and curettage resulted in a curative outcome. The histopathological examination revealed inflammatory granulation tissues, fibrous capsule wall, cholesterol clefts with altered blood pigments, and calcifications, consistent with the diagnosis of cholesterol granuloma. No recurrence was observed for one year after surgery in one case and three years in the other. CONCLUSIONS: When the following features are observed: orbital CT exhibits cystic lesion with irregular bone destruction in the superolateral orbit, magnetic resonance imaging (MRI) depicts lesions are hyperintense signals on T1 weighted images (T1WI), and T2 weighted images (T2WI), and the contrast-enhanced imaging reveals that the most of tumor is showed a non-significant enhancement, orbitofrontal cholesterol granuloma should be considered.

Hammered silver appearance of the corneal endothelium in Fuchs uveitis syndrome: A case report.

BACKGROUND: Hammered silver appearance of the corneal endothelium is considered a characteristic change in iridocorneal-endothelial syndrome. Herein we report an interesting case of hammered silver appearance of the corneal endothelium in Fuchs uveitis syndrome (FUS). CASE SUMMARY: A 49-year-old man with progressive vision loss in the right eye for one year was admitted to our hospital. The clinical manifestations of the patient's right eye were mild conjunctival hyperemia, scattered stellate keratic precipitates on the corneal endothelium, normal depth anterior chamber, 2+ cellular reaction in the aqueous humor, diffuse iris depigmentation, absence of synechia, Koeppe nodules, opalescent lens, and vitreous opacity. FUS and a complicated cataract were diagnosed based on the typical clinical manifestations. The corneal endothelial changes were recorded in detail by slit-lamp examination, specular microscopy, and in vivo confocal microscopy before cataract extraction, revealing a hammered silver appearance of the corneal endothelium in the affected eye, a wide-band dark area, as well as irregular corneal endothelial protuberances and dark bodies of various sizes. Subsequently, the patient underwent phacoemulsification combined with intraocular lens implantation, and his postoperative visual acuity recovered to 1.0. CONCLUSION: Hammered silver appearance of the corneal endothelium in FUS, which is considered a more serious manifestation of endothelial damage, is rare and may be caused by many irregular protrusions in the corneal endothelium.

Clinical characteristics and prognosis of orbital solitary fibrous tumor in patients from a Chinese tertiary eye hospital.

BACKGROUND: Solitary fibrous tumor (SFT) is predominant within the pleura but very rare in the orbit, which is why the diagnosis of orbital SFT poses challenges in clinical practice. Accordingly, an integrated approach that incorporates specific clinical features, histological, histopathological, and immunohistochemical (IHC) examinations, and molecular analyses is warranted. AIM: To retrospectively explore the clinical and imaging characteristics, treatment, outcomes of a series of patients with orbital SFT. METHODS: We conducted a retrospective review of a series of patients diagnosed with a histopathologic orbital SFT treated at a single institution. All data on demogra/phics, clinical characteristics, imaging, treatment, postoperative histopathological and IHC examinations, and prognosis were collected. RESULTS: In total, 13 patients were enrolled, 7 (53.8%) of whom had the tumor located in the superomedial quadrant of the orbit. Computed tomography revealed a solitary ovoid lesion in 10 (76.9%) patients and irregular lesion in 3 (23.1%) patients. Magnetic resonance imaging results were as follows: On T1 weighted images, 3 (23.1%) patients had hypointense mixed signals, whereas 10 (76.9%) patients showed isointense mixed signals; on T2 weighted images (T2WI), 3 (23.1%), 4 (30.8%), and 6 (46.2%) patients exhibited hypointense mixed, isointense mixed, and hyperintense signals, respectively. Notably, 12 (92.3%) patients showed significant enhancement, whereas there were patchy slightly enhanced areas in the tumor. All patients were treated by surgery. IHC analysis demonstrated that the tumor cells were immunoreactive for CD34, CD99, STAT-6, and vimentin in all patients. The lesions showed Ki-67 positivity < 5% in 1 (7.7) patient, 5%-10% in 10 (76.9%), and > 10% in 2 (15.4%). Two (15.4%) patients exhibited tumor recurrence. CONCLUSION: The clinical manifestations and radiologic characteristics of orbital SFT are diverse and not specific. Accurate diagnosis and treatment require detailed radiological and histopathological/IHC evaluation.

Primary orbital monophasic synovial sarcoma with calcification: A case report.

BACKGROUND: Synovial sarcoma is a malignant mesenchymal neoplasm with variable epithelial differentiation. Most synovial sarcoma cases are reported in young adults and can arise in any body site. Notably, primary orbital synovial sarcoma is rare. CASE SUMMARY: An 8-year-old east Asian girl with 1-month history of gradual painless proptosis and lacrimation of the right eye was admitted. The patient presented with painless proptosis, downward eyeball displacement, and upward movement disorders. According to clinical manifestations, imaging examinations and postoperative immunohistochemical examinations, the diagnosis was monophasic synovial sarcoma with calcification. The patient underwent anterior orbitotomy procedure for removal of the right orbital mass under general anesthesia. The diagnosis of monophasic synovial sarcoma with calcification was confirmed finally through histological and immunohistochemical exam. The follow-up period was 6 mo, and no recurrence was observed during this period. CONCLUSION: Primary orbital monophasic synovial sarcoma with calcification is a rare sarcoma, and clinical manifestations and imaging results are not specific. The tumor may present similar features as a benign tumor. Comprehensive analysis of clinical, radiological, and pathological findings is critically important for making the right diagnosis. Conventional treatment approach for synovial sarcoma is surgical resection with adjuvant or neoadjuvant radiotherapy, which is highly effective for localized tumors.

Secondary glaucoma with anterior chamber cholesterolosis: Case series.

RATIONALE: The presence of cholesterol crystals in the anterior chamber is extremely rare, and secondary glaucoma with cholesterol crystals in the anterior chamber, reported in the literature, is even rarer. This paper reports 3 cases of secondary glaucoma with cholesterol crystals in the anterior chamber. PATIENT CONCERNS: Three patients were admitted to the hospital because of ocular distension and blindness. Ocular examination on admission indicated high intraocular pressure, and crystalline gold substances were observed in the anterior chamber. DIAGNOSIS: Based on clinical manifestations and an aqueous fluid smear, absolute glaucoma and anterior chamber cholesterol crystals were diagnosed. INTERVENTIONS: In the first case, transscleral ciliary photocoagulation was performed; in the last 2 cases, trabeculectomy combined with extracapsular cataract extraction was performed. OUTCOMES: The follow-up period was 11 to 15 months. Intraocular pressure was stable in 2 patients treated with surgery, and no cholesterol crystals were observed in the anterior chamber. The intraocular pressure increased in 1 patient treated with laser, and a small amount of cholesterol crystals was still observed in the anterior chamber. LESSONS: Anterior chamber cholesterol crystallization is extremely rare and cannot be treated if it does not cause other lesions. However, glaucoma occurred in all 3 cases in this study, and intraocular pressure increased in 1 case after laser treatment and remained stable in 2 cases after surgical treatment. Therefore, the treatment plan for anterior chamber cholesterol crystallization in glaucoma requires further discussion.

Surgical correction of severe congenital ptosis using a modified frontalis muscle advancement technique: A single-arm trial.

PURPOSE: To describe our experience with a modified frontal muscle advancement flap to treat patients with severe congenital ptosis. METHODS: Analysis of the clinical charts of 154 patients who underwent a modified frontal muscle advancement flap. The FM was exposed by a crease incision. The FM flap was created by deep dissection between the orbicularis muscle and orbital septum from the skin crease incision to the supraorbital margin and subcutaneous dissection from the inferior margin of the eyebrow to 0.5 cm above the eyebrow. No vertical incision was made on the FM flap to ensure an intact flap wide enough to cover the entire upper tarsal plate. Contour, symmetry of height, marginal reflex distance (MRD1), and complications were assessed. Mean follow-up was 10 months. RESULTS: The mean patient age was 7.6 ± 5.6 (range, 2-18) years. The mean MRD1 was 3.2 ± 1.3 mm after the operation. All bilateral cases achieved symmetry and optimal lid contour; 17 unilateral cases were under corrected, with a success rate of 89.0%. Complications such as entropion, exposure keratitis, FM paralysis, frontal hypoesthesia, severe haematoma, and entropion were not observed in our series. CONCLUSION: A modified frontal muscle advancement flap produced a high success rate with a clear field of vision, mild trauma, and few complications. This technique is relatively simple and should be considered for correcting severe congenital ptosis.Date of registration: 29-03-2020Trial registration number: ChiCTR2000031364Registration site: http://www.chictr.org/.

Orbital schwannoma with calcification treated by intracapsular excision: A case report.

RATIONALE: Orbital schwannoma is a relatively rare orbital tumor, and calcification of the lesion is rarely found in the orbit. We report a case of orbital schwannoma which was characterized by calcification in the orbital muscle cone, and was cured by intracapsular excision. PATIENT CONCERNS: A 54-year-old female with a complaint of a mass in the left orbit during a magnetic resonance imaging examination and symptom of dizziness 6 months before, presented with painless exophthalmos and vision decline in the left eye. DIAGNOSES: According to clinical manifestations, imaging examinations and postoperative immunohistochemical examinations, the diagnosis was orbital schwannoma, with calcification in the muscle cone. INTERVENTIONS: The patient was treated by intracapsular excision of the left orbit. We removed the intracapsular mass and most part of the cyst wall in order to prevent orbital apex syndrome. OUTCOMES: The diagnosis of schwannoma with calcification was confirmed finally through histological and immunohistochemical exam. The patient was followed up for 28 months and the orbital CT scan showed that there were no significant lesions found in the orbital muscle cone. LESSONS: Understanding clinical, imaging diagnostic, and histopathological features of rare orbital schwannoma with calcification will facilitate timely diagnosis and treatment of this condition. The intracapsular excision can help in avoiding complications.
