1/16. Herpes zoster sine herpete presenting with hyphema.PURPOSE: To report a case of herpes zoster sine herpete presenting with hyphema. methods: A 69-year-old man was referred for traumatic hyphema and corneal edema in his left eye after a sandblast exposure three weeks previously. Slit-lamp examination demonstrated hyphema, anterior chamber inflammation, mid-dilated pupil, impaired corneal sensation, and high intraocular pressure, without any facial skin lesions. iris fluorescein angiography revealed tortuosity and extensive occlusion of iris vessels. The patient was treated with oral acyclovir and intensive topical steroids with a presumed diagnosis of severe herpes zoster uveitis. RESULTS: Clinical findings improved dramatically within several days. Typical sectorial iris atrophy with pupillary sphincter dysfunction and complete loss of corneal sensation developed after the resolution of intraocular inflammation. CONCLUSION: herpes zoster should be considered in patients with uveitis and hyphema even in the absence of typical skin rash.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
2/16. Recurrent hyphema in an aphakic child: Swan syndrome.In 1973, Swan described 3 patients who developed hyphema months to years after uncomplicated cataract surgery. He noted focal vascularization from an ingrowth of episcleral vessels at the cataract wound site, resulting in recurrent intraocular bleeding. Swan syndrome has been reported following intracapsular cataract extraction, extracapsular cataract extraction (including clear corneal incisions), iridocyclectomy, and glaucoma filtering procedures. patients typically present with sudden painless blurred vision, often upon awakening, which may or may not be preceded by physical strain or trauma. Other patients are asymptomatic and diagnosed with hyphema or anterior chamber red blood cells on routine examination. The hyphema often resolve spontaneously, making later diagnosis difficult. Gonioscopic visualization of the abnormal wound vessels is necessary for diagnosis. Without active bleeding, however, the fibrovascular tuft may be easily overlooked. We report a case of Swan syndrome in a 16-month-old boy after cataract extraction was performed. To our knowledge, Swan syndrome has not been reported in the pediatric population. Children represent a significant proportion of patients undergoing anterior segment surgery and Swan syndrome should be considered in the differential diagnosis of hyphema in this population.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
3/16. anterior chamber hemorrhage during cataract surgery in Lowe syndrome.This article reports a spontaneous intracameral bleeding at the end of cataract surgery in both eyes of two patients with Lowe syndrome. Extracapsular cataract extraction with anterior vitrectomy and posterior capsulotomy, using the anterior chamber maintainer (ACM), was performed in both eyes of two patients. At the conclusion of the surgery, when the ACM was removed, spontaneous bleeding occurred into the anterior chamber and spread into the vitreous cavity. The hemorrhage resolved spontaneously over varying periods of time. We propose that bleeding occurred from damage to iris vessels in the abnormal angle in our patients with Lowe syndrome when the ACM was removed with a concomitant decrease in intraocular pressure.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
4/16. Spontaneous hyphema and vessel anomaly.We describe a case of spontaneous hyphema, in which results of fluorescein angiography revealed that the condition was caused by anomalous iris vessels. A cavernous hemangloma of the ipsilateral orbit was discovered. We stress the importance of performing fluorescein angiography in all cases of spontaneous hyphema.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
5/16. Bleeding during gonioscopy after deep sclerectomy.PURPOSE: To show a new complication after deep sclerectomy (DS). methods: We described two eyes of two patients with open-angle glaucoma and cataract who were operated on of an uneventful phacoemulsification and DS with SK-gel implantation. RESULTS: Bleeding during gonioscopic examination occurred in both eyes 7 and 8 months after combined surgery. The blood originated from the vessels around the Descemet window, and was probably due to manipulation or rocking of the goniolens. Pressure was immediately applied to the gonioscopic lens and the hyphema was interrupted. CONCLUSION: These cases show the presence of new vessels around the Descemet window after DS with SK-gel. Bleeding from the Descemet window vessels can occur during gonioscopy even months after DS. We recommend conducting a careful gonioscopic examination in patients who have undergone DS to avoid this complication.- - - - - - - - - - ranking = 3keywords = vessel (Clic here for more details about this article) |
6/16. Central retinal vein occlusion and iris neovascularization hemorrhage.Although there have been few direct observations, the etiology of spontaneous hyphema in patients with retinal or ocular hypoxia is assumed to be hemorrhage from a neovascular iris vessel. This paper reports observed hemorrhage from such a rubeotic iris in a patient with central retinal vein occlusion, diabetes, hypertension, peripheral vascular disease and chronic open-angle glaucoma. Bleeding was spontaneous with dilation, but stopped within 24 hours without treatment, leaving only traces of inferior angle blood staining. The two types of central retinal vein occlusion, and suggestions for their management, are also discussed.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
7/16. Spontaneous hyphaema and corneal haemorrhage as complications of microbial keratitis.Hyphaema developed spontaneously in 16 of 458 patients with microbial keratitis treated at two centres on the East and West Coasts of the united states. Chronic corneal conditions were often present, and three cases had rubeosis iridis. Inflamed iris vessels were assumed to be the source of the haemorrhage. The hyphaemas tended to persist longer than is usual, particularly when coincident with a hypopyon. Recurrent hyphaemas are reported in two patients from outside this series. Spontaneous corneal haemorrhage was seen in three cases. Subepithelial bleeding settled rapidly, but a combined midstromal and pre-Descemet's haematoma cleared more slowly. Anterior segment bleeding was significantly associated with advanced age, female sex, infection with Gram-positive organisms, and hypopyon.- - - - - - - - - - ranking = 1keywords = vessel (Clic here for more details about this article) |
8/16. argon laser treatment of an abnormal angle vessel producing recurrent hyphema.Spontaneous hyphema has been linked to many conditions. We describe a patient with recurrent spontaneous hyphema caused by an abnormal angle vessel without associated rubeosis iridis, glaucoma, or other vascular abnormalities as documented by iris fluorescein angiography. After treatment with several sessions of argon laser photocoagulation, the patient has remained asymptomatic during ten months of follow-up.- - - - - - - - - - ranking = 5keywords = vessel (Clic here for more details about this article) |
9/16. argon laser photocoagulation of inner wound vascularization after cataract extraction.A 64-year-old man had vascular ingrowth of a surgical wound resulting in recurrent hyphema and pupillary block glaucoma three years after cataract extraction. argon laser photocoagulation of an abnormal vessel in the inner lip of the wound resulted in complete clearing of a chronic hyphema, with a four-month follow-up. We used 500-micron laser spots of 2,000 mW and 0.5 seconds' duration to closr the vessels. This approach is recommended for its relative safety and simplicity.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
10/16. Intraocular hemorrhage from vascularization of the cataract incision.In a survey of 58 aphakic eyes examined 5 to 10 years after surgery, 12% had episcleral vessels in the inner aspect of the cataract incision and almost half of these eyes showed evidence of mild intraocular hemorrhage. Analysis of these and 33 other eyes indicates that argon laser treatment is only temporarily effective in preventing intraocular hemorrhage. Limbal cryotherapy is effective in a one- to four-year follow-up. While these vessels are a common cause of transient intraocular hemorrhage in aphakic eyes, serious sequelae are rare and treatment is usually unnecessary.- - - - - - - - - - ranking = 2keywords = vessel (Clic here for more details about this article) |
