1/40. Venous collateral remodeling in a patient with posttraumatic glaucoma.PURPOSE: To photographically document venous collateral development, remodeling, and regression in a patient with traumatic glaucoma. methods: Consecutive fundus photographs were evaluated, labeled, and correlated with the clinical history of a patient with unilateral posttraumatic glaucoma. RESULTS: This report photographically documents the appearance, remodeling, and subsequent disappearance of collateral vessels from venous occlusion on the surface of the optic disk in an eye with increased intraocular pressure and progressive glaucomatous cupping. CONCLUSIONS: Asymptomatic chronic obstruction of a branch retinal vein on the optic disk may cause venous collaterals to develop in the absence of retinal hemorrhages or other signs of venous occlusive disease. Increased intraocular pressure, arteriolarsclerosis, and glaucomatous cupping are risk factors for these occlusions.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/40. A case of glaucoma with choroidal hemangioma managed by nonpenetrating trabeculectomy.BACKGROUND: Nonpenetrating trabeculectomy was used in a patient with glaucoma complicated by diffuse choroidal hemangioma. CASE: A 12-year-old boy suffered from glaucoma with choroidal hemangioma in the left eye. intraocular pressure was 28 mm Hg and visual acuity was 0.04. Nonpenetrating trabeculectomy was then performed. OBSERVATIONS: Postoperative intraocular pressure was controlled at around 15 mm Hg with pilocarpine hydrochloride eye drops. visual acuity and visual field were preserved over 19 months after the operation. CONCLUSIONS: An increase in aqueous outflow resistance was considered to be the major mechanism in the rise in intraocular pressure, based on distinct dilatation and tortuosity of the episcleral blood vessels and congestion of Schlemm's canal. Therefore, construction of aqueous drainage by nonpenetrating trabeculectomy was effective. Retaining the trabecular meshwork was also considered effective in controlling complications such as choroidal hemorrhage and postoperative flat anterior chamber.- - - - - - - - - - ranking = 5.5925017604701keywords = blood vessel, vessel (Clic here for more details about this article) |
3/40. Spontaneous expulsive suprachoroidal hemorrhage.PURPOSE: To present a 90-year-old patient with spontaneous expulsive suprachoroidal hemorrhage (SESCH). This unique case suggests a mechanism of SESCH, which is still under debate. methods: The patient, who had corneal inflammatory disease and diabetes mellitus, atherosclerosis, and glaucoma, presented with active ocular bleeding and expulsion of intraocular tissues. Almost the entire cornea was absent, except for several small and irregular areas in its periphery. Histopathologic evaluation of the eviscerated contents was performed. RESULTS: Clinicopathologic evaluation revealed acute inflammation of the corneal remains as well as intraocular inflammation. Inflammatory necrosis of choroidal vessels was evident. CONCLUSION: The findings point to the assumption that choroidal bleeding, secondary to vascular inflammatory necrosis, was the initial event in this case of spontaneous expulsive suprachoroidal hemorrhage. Presumedly, the intraocular pressure level was very high owing to continuous bleeding, which could result in a very large, rather than localized, tearing of the peripherally inflamed cornea.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/40. Glaucomatous optic nerve head changes with scanning laser ophthalmoscopy.PURPOSE: To determine whether there are angiographic differences among normal, preperimetric and advanced glaucoma eyes using indocyanine green angiography with SLO. This method was chosen because of its sensibility to detect peripapillary capillary vessels. methods: Scanning laser opthalmoscopy was preformed on normal eyes, preperimetric glaucomas and advanced glaucomas. MATERIAL: The authors used a confocal SLO (Heidelberg Retina Angiograph-HRA) CONCLUSION: Several changes may be seen on peripapillary capillary vessels at the different glaucomatous stages. DISCUSSION: In normal subjects HRT shows preservation of the disc/cup area ratio; indocyanine green angiography shows normal prepapillary plexus pattern on the neuroretinal rim and cup. Subjects on glaucomatous preperimetric stage reveal a decrease in the disc/cup area ratio as a result of an increase of the cup area secondary to a reduction of the neuroretinal rim area. ICG at this hipertensive stage shows an increase in prepapillary plexus visualization, which may be a consequence of increased blood flow while autoregulation is still operative. Subjects with advanced glaucoma show prominent decrease in the disc/cup area ratio as well as marked capillary droupout in ICG angiography.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
5/40. Multifocal choroiditis in patients with familial juvenile systemic granulomatosis.PURPOSE: To document clinical features of uveitis in patients with familial juvenile systemic granulomatosis. DESIGN: Retrospective chart review. methods: Ophthalmologic examination, medical history, and clinical course in 16 patients from eight families examined at six academic medical centers. RESULTS: Of the 16 patients, 15 had evidence of panuveitis with multifocal choroiditis. One patient had only an anterior uveitis. Ischemic optic neuropathy, presumably due to a small vessel vasculopathy, and retinal vasculopathy each occurred in one patient. Ocular complications were common, including cataracts in 11, glaucoma in six, band keratopathy in six, cystoid macular edema in six, and optic disk edema in six. All 16 patients had polyarthritis, and at least nine had skin rash. Often patients were misdiagnosed initially as having either juvenile rheumatoid arthritis or sarcoidosis. CONCLUSIONS: Familial juvenile systemic granulomatosis is an uncommon genetic disease characterized by polyarthritis and uveitis. panuveitis and multifocal choroiditis often may be present. patients with a diagnosis of juvenile rheumatoid arthritis but having a family history of the disease and multifocal choroiditis should be suspected of having familial juvenile systemic granulomatosis.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
6/40. Acute glaucoma in hemorrhagic fever with renal syndrome (nephropathia epidemica).Bilateral eyelid edema, chemosis, conjunctival injection and hemorrhages, shallowing of the anterior chamber with transitory myopia, and acute glaucoma were observed in three patients with hemorrhagic fever with renal syndrome (nephropathia epidemica). One patient had anterior uveitis with posterior synechiae. Two patients had congestion of retinal venules and retinal edema, and one patient had small retinal hemorrhages. fluorescein angiography revealed early leakage of the conjunctival capillaries and delayed filling of the lower retinal arterioles with retinal edema. The acute glaucoma subsided rapidly. The myopia disappeared slowly with a gradual deepening of the anterior chamber after onset of the diuretic phase of the illness. In nephropathia epidemica, the transitory shallowing of the anterior chamber, myopia, and acute glaucoma are due to lesions in the small blood vessels of the ciliary body, resulting in its swelling, with relaxation of the zonules and forward movement of the lens.- - - - - - - - - - ranking = 5.5925017604701keywords = blood vessel, vessel (Clic here for more details about this article) |
7/40. Late histopathological findings of neodymium:YAG laser iridotomies in humans.We studied three sector iridectomy specimens from three patients who had undergone neodymium:YAG (Nd:YAG) laser iridotomies 3 to 5 years earlier for treatment of imminent angle closure glaucoma. The specimens were obtained during cataract extraction and were examined by light and transmission electron microscopy. In all iris specimens, the edges of the iridotomy sites consisted of loosely arranged melanocytes, fibrocytes, and vessels. In the iris stroma, there were numerous pigment-laden cells. The iris vessels appeared to be intact; there were no fibrinous aggregates, no inflammatory response or scarring, nor any signs of proliferation of the iris pigment epithelium. Our findings suggest that in humans, iris wound healing after Nd:YAG laser iridotomy occurs without induction of fibrous scars or proliferation of the iris pigment epithelium. This indicates that there is no tendency toward late closure of the iridotomy sites.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
8/40. A case of developmental glaucoma presenting with abdominal colic and subnormal intraocular pressure.A healthy baby boy presented with abdominal colic. He was subsequently noted to have enlarged, edematous corneas. A clinical diagnosis of developmental glaucoma was made despite ocular hypotony. Trabeculectomies were designed to include peripheral cornea. This served as a biopsy to confirm the diagnosis and as a surgical treatment for the condition. Morphological examination of the outflow system revealed findings compatible with a diagnosis of developmental glaucoma: a hypoplastic trabecular meshwork which contained an abundance of abnormal collagenous tissue in the extracellular spaces and the presence of endothelial cells overlying a continuous collagenous membrane. In the iris stroma there were numerous abnormal blood vessels, with a paucity of mural contractile cells.- - - - - - - - - - ranking = 5.5925017604701keywords = blood vessel, vessel (Clic here for more details about this article) |
9/40. Preserved vision despite distinct retinal edema in central retinal artery occlusion.BACKGROUND: In subtotal central retinal artery occlusion (CRAO), distinct retinal edema with acute onset irreversible visual loss is common. - methods: Clinical observation, fluorescein angiogram. - PATIENT: A 69-year-old patient presented with acute visual loss of his right eye. risk factors for CRAO were arterial hypertension and diabetes mellitus. A further factor was a 60% stenosis of the right and a 90% stenosis of the left internal carotid arteries. - RESULT: Visual acuity at initial examination was 20/32 despite pronounced central retinal edema with characteristic cherry red spot of the macula. fluorescein angiography demonstrated early filling of retinal vessels, only perfusion of the inferior macular vessels was delayed. Two months later retinal edema resolved and central visual acuity was 20/25. - CONCLUSION: In this patient, retinal edema most likely resulted from a transient retinal ischemia. Spontaneous reperfusion occurred early enough to allow functional recovery in the ischemic retina.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
10/40. Multiple retinal hemorrhage following anterior chamber paracentesis in uveitic glaucoma.PURPOSE: We describe the occurrence of a massive retinal hemorrhage following anterior chamber paracentesis in uveitic glaucoma. methods: A 33-year-old man who suffered from uveitic glaucoma was transferred to our hospital. The lOP in both his eyes was documented to vary between 11 mmHg and 43 mmHg and remained at a continuously high level for 7 months despite maximally tolerable medical treatment. A paracentesis was performed bilaterally to lower the IOP. RESULTS: Immediately after the paracentesis, massive retinal hemorrhages occurred in the left eye. Multiple round blot retinal hemorrhages with white centers occurred in the equator and peripheral retina, and small slit hemorrhages were observed in the peripapillary area. A fluorescence angiography(FAG) showed no obstruction of retinal vessels but a slightly delayed arteriovenous time in the left eye. CONCLUSIONS: It is important to be aware that patients who have a persistent relatively high IOP are at an increased risk of developing decompression retinopathy due to paracentesis and filtering surgery.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
