This study aimed to explore the clinical, radiological, and pathological characteristics of intraocular cysticercosis due to Taenia solium metacestode infection. Total 8 patients diagnosed with intraocular cysticercosis at the Red Cross Hospital of Yunnan Province, China were examined retrospectively. Patients with clear dioptic media had undergone fundus chromophotography. All patients underwent B ultrasonography of the ocular region (CT) successive scanning of the orbit and cerebral tissues. Parasites were extracted surgically and then examined pathologically. The fundus chromophotography showed a white and condensing scolex package in the vesicle. The B ultrasonic examination showed a vesicle-like echogenic mass in the vitreous chamber, in which the high-level echo spot was the cysticercus scolex. The pathological examinations showed that the vesicle wall exhibited hyaline degeneration, inflammatory cell infiltration, neuroglial fiber, and glial cell proliferation layers from the inside to the outside. The scolex is round and is composed of the outer tissue (the body wall) and the inner furrow tissue; these tissues migrated together. Primordially differentiated sucking discs were found in one case, but no hooklets were found. The inner scolex tissue was folded like a paper flower. The severity of intraocular disease is closely correlated with the pathophysiological processes of the cysticercus worm. Pathological examination of the intraocular lesions can help to evaluate the course of the disease as well as to provide a scientific basis for effective antiparasitic medication.

PURPOSE: To compare preoperative and postoperative ocular biometry in patients with iris-fixated phakic intraocular lens (pIOLs): Artisan and Artiflex. MATERIALS AND METHODS: This study included 40 eyes with Artisan and 36 eyes with Artiflex pIOL implants. Anterior chamber depth (ACD) and axial length (AL) were measured by applanation ultrasonography (A-scan) and partial coherence interferometry (IOLMaster) preoperatively and 3 months after pIOL implantation. RESULTS: ACD measurements after Artisan or Artiflex pIOL implantation were smaller than preoperative measurements. Specifically, the difference after Artisan pIOL implantation was -1.07+/-0.17 mm by A-scan and -0.08+/-0.08 mm by IOLMaster. The difference after Artiflex pIOL implantation was -1.31+/-0.15 mm by A-scan and -0.05+/-0.07 mm by IOLMaster. After Artisan pIOL implantation, differences in AL measurements by A-scan were insignificant (difference: -0.03+/-0.15 mm), whereas postoperative AL measurements by IOLMaster were significantly longer than preoperative measurements (difference: 0.12+/-0.07 mm). After Artiflex pIOL implantation, AL measurements by both A-scan and IOLMaster were significantly longer than preoperative measurements (difference: 0.09+/-0.16 mm by A-scan and 0.07+/-0.10 mm by IOLMaster). In the Artiflex group, differences in AL measurements by A-scan correlated with the central thickness of the Artiflex pIOL. CONCLUSION: ACD and AL measurements were influenced by iris-fixated phakic IOL implantation.

Orbital metastasis from hepatocellular carcinoma is very rare, with only 14 biopsy-proven cases from hepa tocellular carcinoma cases reported in English literature and three cases reported in Korea. Common symptoms of orbital metastasis are proptosis, visual loss, ocular pain and oculomotor dysfunction. For its precise diagnosis, we can perform fine needle aspiration biopsy, orbit CT or MRI, and ultrasonography. Radiotherapy is the mainstay in the treatment of orbital metastasis. In addition, chemotherapy, hormonal therapy and surgical intervention can play a role in the treatment of orbital metastasis according to the primary cancer and symptoms. However, the prognosis of orbital metastasis is poor. We report herein a rare case of a patient with orbital metastasis from hepatocellular carcinoma, which was treated with various modalities that included resection, and who had good clinical and radiological responses to radiation therapy and sorafenib (Nexavar, Bayer HealthCare).

A 68-year-old woman presented with pain in her left eye. Necrosis with calcium plaques was observed on the medial part of the sclera. Aspergillus fumigatus was isolated from the culture of the necrotic area. On systemic work-up including serum and urine electrophoresis studies, the serum monoclonal protein of immunoglobulin G was detected. The patient was diagnosed with monoclonal gammopathy of undetermined significance and fungal scleritis. Despite intensive treatment with topical and oral antifungal agents, scleral inflammation and ulceration progressed, and scleral perforation and endophthalmitis developed. Debridement, antifungal irrigation, and tectonic scleral grafting were performed. The patient underwent a combined pars plana vitrectomy with an intravitreal injection of an antifungal agent. However, scleral and intraocular inflammation progressed, and the eye was enucleated. Aspergillus fumigatus was isolated from the cultures of the eviscerated materials. Giemsa staining of the excised sclera showed numerous fungal hyphae.

Retinoblastoma, the most common primary intraocular malignancy of childhood, usually presents in the first three years of life. Atypical presentation of retinoblastoma can masquerade as virtually any ocular or orbital pathology, which may lead to diagnostic dilemmas especially in the presence of other systemic diseases. We report a 20-month-old boy who was diagnosed with coronary aneurysm as a complication of Kawasaki disease, and presented with sudden left eye redness. His mother noticed the presence of white pupillary reflex three months earlier. Atypical acute ocular presentation secondary to Kawasaki disease was initially suspected, but the presence of multiple calcification and mild proptosis on imaging suggested characteristics of advanced retinoblastoma. Histopathological examination of the enucleated eye, which revealed a classical rosette pattern appearance, confirmed the diagnosis. Atypical presentations of retinoblastoma are usually associated with advanced disease. The presence of other systemic conditions further complicates the diagnosis. Early diagnosis is important to reduce the mortality and morbidity.

PURPOSE: To determine the pathogenesis of transient myopia after blunt eye trauma. METHODS: In one patient, the refraction of both eyes (the left eye was injured, but the right eye was not) was measured with an autorefractometer. The cycloplegic refraction was measured at the early stage of trauma and again 3 months after the blunt eye injury. The angle and depth of the anterior chamber, the ciliary body, and the choroids were examined by ultrasound biomicroscopy (UBM) over 3 months. The depth of the anterior chamber, the thickness of the lens, and the axial length were measured by A-scan ultrasonography in both eyes. During the 3 months after the injury, we made comparisons between the menifest and the cycloplegic refractions, the depths of anterior chambers, the thickness of the lenses, the axial lengths, and the UBM-determined appearances of the angles and depths of the anterior chambers, the ciliary bodies, and the choroids in both eyes. RESULTS: We suspect that the depth reduction in the anterior chamber, the increase in anterior to posterior lens diameter, and the edema in the ciliary body are all related to the change in the refractive power following the blunt trauma. CONCLUSIONS: Ultrasound biomicroscopy (UBM) and ultrasonography of the anterior segment in the eye may be helpful to diagnose and confirm changes in the refractive power that occur after trauma.

PURPOSE: To report a case of endogenous endophthalmitis due to Aeromonas hydrophila in a patient with distal common bile duct carcinoma and biliary sepsis. METHODS: A 72-year-old woman with distal common bile duct carcinoma, obstructive jaundice, diabetes mellitus, and hypertension had a 1-day history of blurred vision, redness, and eye discharges in the right eye. An ophthalmic examination showed no light perception vision, increased intraocular pressure, severe corneal edema, severe anterior chamber reaction, exudative membranes on the anterior lens surface, and severe vitreal reaction. There was no ocular history of trauma, infection, or surgery in either eye. RESULTS: Under the impression of endogenous bacterial endophthalmitis, immediate intraocular cultures and intravitreal antibiotic injections were performed, but the anterior chamber reaction, and the ultrasonogram findings were deteriorated. Evisceration was undertakened because of extrusion of the intraocular contents, and Aeromonas hydrophila was isolated by intraocular culture. CONCLUSIONS: Endogenous endophthalmitis due to Aeromonas hydrophila is rare, but has a rapid clinical course and a poor prognosis, despite of prompt diagnosis and management.

INTRODUCTIONThe aim of this study was to investigate the role of ultrasound biomicroscopy (UBM) in imaging anterior segment foreign bodies and compare it with conventional B-scan ultrasound and computed tomography (CT).

MATERIALS AND METHODSThe charts of 18 eyes with anterior segment foreign bodies were reviewed. The rates of detection of foreign bodies using ultrasound, CT scan and UBM were compared.

RESULTSThe foreign body detection rates were 36.5% by ultrasound, 88.9% by CT scan, and 94.4% by UBM. The diagnosis of presence of a foreign body using UBM was made based on high reflective echoes causing shadowing or reverberations. In 7 eyes, UBM detected injury to the zonules, guiding the operative procedure. In the 8 eyes for which all tests were performed, rates of detection of foreign bodies were 25% (2/8) with ultrasound, 87.5% (7/8) with CT, and 100% (8/8) with UBM.

CONCLUSIONUBM is a valuable adjunct for the accurate localisation of small foreign bodies, including cilia. It offers a higher detection rate than that provided by ultrasound and CT scan.

Objective: This study correlated the patterns of ocular B- and A-scans of intraocular retinoblastoma (RB) with corresponding histopathology sections. It aimed to establish a more objective basis for determining intraocular retinoblastoma by ultrasonography (UTZ) and to determine the degree of malignancy and viability of the tumor cells. Methods: New cases of retinoblastoma seen at the University of the Philippines-Philippine General Hospital (UP-PGH) from January 1994 to December 2003 were reviewed. Included were patients who underwent enucleation and whose eyeballs were processed at the UP Institute of Ophthalmology. Those with good quality ocular ultrasonographs (UTZ) and clear matching histopathologic sections were finally selected. Findings were correlated and analyzed.Results: Retinoblastoma (RB) showed multiplicity of lesions on UTZ corresponding to multiple lesions on histopathology. The following characteristic patterns were seen: Very malignant RB or pseudorosettes: fine, grainy densities on B-scan with short to medium broad spikes on A-scan ("V-W" pattern). Moderate differentiation with moderate necrosis and early calcific plaques: fine, dense grainy opacities on B-scan with multiple thin, high spikes admixed with tall, broad spikes of calcium deposits on A-scan. Well-differentiated RB with compact viable cells and no necrosis: large, white densities on B-scan with an initial high spike and high internal reflectivity, sometimes "plateauing," on A-scan with no calcific deposits. Complete tumor necrosis with calcific plaques: echolucent space with dense, white, plaque-like opacities on B-scan; flat or low spikes mixed with tall, broad spikes corresponding to calcium plaques on A-scan. Normal vitreous, serous subretinal fluid, or recent hemorrhage: echolucent area on B-scan with flat or low spikes on A-scan. Conclusion: The three most frequent findings in intraocular retinoblastoma were calcific plaques with liquefaction necrosis, multiplicity of lesions, and pseudorosettes. Ocular ultrasound of retinoblastoma showed good histopathologic correlation.
