1/7. pathology of a lepromatous eye.Histopathological examination of an enucleated eye from a lepromatous leprosy patient showed the cornea, ciliary body, and part of the choroid to be infiltrated by macrophages filled with mycobacterium leprae. The walls of blood vessels in the sclera, ciliary body and the anterior choroid demonstrated the presence of M. leprae, giving credence to the blood-borne entry of M. leprae into the eye. Unlike the eyes of experimental animals infected with M. leprae, histopathological study of this eye from a lepromatous leprosy patient demonstrated that M. leprae, although demonstrable in the anterior choroid, could not be found in the posterior parts of the eye, substantiating the claim that leprosy does not affect the posterior parts of the eye directly.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/7. corneal ulcer of the side port after phacoemulsification induced by acinetobacter baumannii.A 75-year-old man had clear corneal phacoemulsification using a temporal approach in the left eye. Two months after surgery, a focal corneal epithelial defect developed with infiltration near the lower limbus on the site of the side-port incision. The culture of corneal scrapping grew acinetobacter baumannii, which is resistant to most ordinary antibiotics in sensitivity tests. After appropriate antibiotic treatment, the ulcer healed gradually with vessel ingrowth. acinetobacter baumannii is usually found in nosocomial infection of immune-compromised patients in the intensive care unit. It is a rare pathogen of infectious keratitis. Our case, with its unusual infection site, may point to potential risk factors for this pathogen.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
3/7. vitreous hemorrhage as the initial presentation of postoperative endophthalmitis.PURPOSE: To describe a patient with postoperative endophthalmitis whose only abnormal finding at presentation was a vitreous hemorrhage. DESIGN: Interventional case report. methods: A 68-year-old diabetic woman underwent cataract extraction with intraocular lens implantation in the left eye. Three days after surgery, she had painless loss of vision, minimal anterior chamber inflammation, and dense vitreous hemorrhage in the left eye. RESULTS: On the fourth postoperative day, significant anterior chamber inflammation developed with fibrin and a hypopyon. During vitrectomy with intravitreal antibiotic injection, an area of retinitis surrounding an eroded retinal blood vessel was found. Cultures of undiluted vitreous fluid grew coagulase-negative staphylococcus organisms. The endophthalmitis resolved and 20 months later, her best-corrected visual acuity had improved to 20/40. CONCLUSION: Postoperative endophthalmitis may present as a vitreous hemorrhage, secondary to retinitis and erosion of a retinal blood vessel.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
4/7. Fluorescein angiographic findings in an infected scleral buckle.This report presents fluorescein angiographic (FA) findings in a patient with scleral buckle infection. Ten days following scleral buckling surgery, FA demonstrated dilated choroidal vessels over the buckle with leakage of fluorescein into the subretinal space. Irregular diffuse scleral thickening was noted on the computed tomography (CT). The findings of focal choroiditis with dilated leaky choroidal vessels seen on FA, or diffuse scleral thickening demonstrated by a CT may aid in establishing the diagnosis of scleral buckle infection.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/7. retinal vasculitis due to secondary syphilis.BACKGROUND: retinal vasculitis is one of the manifestations of ocular syphilis. CASE: A 29-year-old man was referred to our hospital with the complaint of sudden visual loss in the left eye lasting more than three weeks. OBSERVATIONS: Ophthalmoscopic examination showed retinal hemorrhages, edema, and sheathing of large retinal arteries and veins. fluorescein angiography revealed extensive occlusion of the affected retinal arteries, veins, and capillaries. Little evidence of uveitis or vitritis was observed. The fluorescent treponemal antibody-absorption test was positive, and the treponema pallidum hemagglutination titer was 1:10,240. The treatment with penicillin was effective, leading to resolution of the retinal hemorrhages and edema, although occlusion of the retinal vessels persisted. CONCLUSIONS: Vascular occlusion occurred simultaneously in large retinal arteries, arterioles, and capillaries as well as in segments of retinal veins, resulting in irreversible changes in the vascular walls.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/7. indocyanine green angiography anomalies in ocular syphilis.OBJECTIVE: To report indocyanine green (ICG) angiography anomalies in ocular syphilis. DESIGN: A noncomparative, interventional case series. PARTICIPANTS: Eight patients (16 eyes) affected by ocular syphilis. methods: All patients presenting with a diagnosis of active ocular syphilis between January 1994 and December 2001 were evaluated by a standard fluorescein and ICG angiography protocol. ICG angiography was repeated after completion of systemic antitreponemal and antiinflammatory treatment. RESULTS: ICG angiography anomalies were detected in 12 (75%) of 16 eyes. Two types of anomalies were observed: late-phase scattered hyperfluorescent spots (11 eyes) and persistent staining of retinal vessels (1 eye). Of these 12 eyes, 4 had no alteration by concomitant fluorescein angiography. When ICG angiography was repeated (5 /- 1 weeks after the beginning of treatment), ICG angiography anomalies disappeared. CONCLUSIONS: ICG angiography may be a valuable tool in the assessment of patients with active ocular syphilis. Retinal and choroidal vascular anomalies can be determined that would otherwise go undetected by funduscopy and/or fluorescein angiography. It can also be useful in monitoring antitreponemal therapy.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/7. Conjunctival injection, episcleral vessel dilation, and subconjunctival hemorrhage in patients with new tsutsugamushi disease.Tsutsugamushi disease is found in two types: classical and new. There have been very few reports describing the ocular findings in patients with the new form. We have described four patients with this type, selected according to their clinical and laboratory findings, including immunofluorescent titers and polymerase chain reaction results. Eyes were examined by standard ophthalmic procedures. Patient 1 had bilateral conjunctival injection and subconjunctival hemorrhage; patients 2-4 had conjunctival injection and episcleral vessel dilation bilaterally. We believe that conjunctival injection is found in most eyes of patients with new tsutsugamushi disease.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
