1/56. Rotoextractor evacuation of total hyphema.hyphema was created in ten albino rabbits and removed within an hour by the Douvas Rotoextractor. All the blood was gone from each eye within 48 hours and there was no evidence of damage to iris, cornea or lens after six weeks. One patient underwent Douvas Rotoextractor removal of a hyphema that was causing increased intraocular pressure and corneal staining. Three months postoperatively, vision was 6/7.5 and intraocular pressure was controlled.- - - - - - - - - - ranking = 1keywords = pressure (Clic here for more details about this article) |
2/56. Endocapsular hematoma: report of a case following glaucoma surgery in a pseudophakic eye.The authors describe a case of an endocapsular hematoma that occurred in a 69-year-old pseudophakic diabetic male following mitomycin C (MMC) augmented trabeculectomy for neovascular glaucoma (NVG). The clinical course of the patient is described, and the unique features of this case are presented and discussed. The endocapsular hematoma absorbed in 6 weeks with conservative management. The patient regained the preoperative visual acuity of 20/30, and his intraocular pressure was controlled without any glaucoma medication. The iris neovascularization regressed. This case is the first report of an endocapsular hematoma following glaucoma filtering surgery in a pseudophakic eye with neovascular glaucoma.- - - - - - - - - - ranking = 0.5keywords = pressure (Clic here for more details about this article) |
3/56. Transpupillary argon laser cyclophotocoagulation in the treatment of traumatic glaucoma.PURPOSE: A patient with traumatic glaucoma who underwent transpupillary argon laser cyclophotocoagulation for management of uncontrolled intraocular pressure (IOP) despite maximally tolerated medical therapy is discussed. methods: In this patient, pars plana vitrectomy, lensectomy, and removal of 180 degrees of necrotic iris had been performed after a blunt trauma with a bungee cord. Six weeks after surgery, the patient presented with an IOP of 40 mmHg despite therapy with three aqueous suppressants. The patient refused further surgical intervention and opted for transpupillary argon laser cyclophotocoagulation (talc). The laser setting was 1,000 mW, with a 50-micron spot size for 0.1 second. A total of 293 laser exposures through a Goldmann contact lens was administered to all visible ciliary processes over 180 degrees where iris structures were absent. RESULTS: Ten weeks after talc, the patient's IOP remained controlled with medications at 16 mmHg, and visual acuity had improved to 20/25 with an aphakic contact lens. CONCLUSION: In selected patients whose ciliary processes are visible with indirect gonioscopy due to the defect in the iris, talc may be an effective alternative cyclodestructive procedure to lower IOP when conventional medical or laser treatments are not successful.- - - - - - - - - - ranking = 0.5keywords = pressure (Clic here for more details about this article) |
4/56. hyphema caused by a metallic intraocular foreign body during magnetic resonance imaging.PURPOSE: To report a 63-year-old man with a retained intraocular foreign body who developed a hyphema during magnetic resonance imaging (MRI) of the brain. methods: Case report and review of the current literature on ocular injury caused by intraocular foreign bodies when subjected to an electromagnetic field. RESULTS: Our patient underwent a brain MRI, and the intraocular foreign body caused a hyphema and increased intraocular pressure. The presence and location of the intraocular foreign body were determined by computed tomography (CT). CONCLUSION: magnetic resonance imaging can cause serious ocular injury in patients with ferromagnetic intraocular foreign bodies. This case demonstrates the importance of obtaining an occupational history, and, when indicated, a skull x-ray or CT to rule out intraocular foreign body before an MRI study.- - - - - - - - - - ranking = 0.5keywords = pressure (Clic here for more details about this article) |
5/56. 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 = 0.5keywords = pressure (Clic here for more details about this article) |
6/56. Transcorneal oxygen therapy for glaucoma associated with sickle cell hyphema.PURPOSE: To study three patients with glaucoma caused by sickle cell hyphema who were successfully treated with transcorneal oxygen therapy. methods: case reports. Three patients with increased intraocular pressure caused by sickle cell hyphema were administered transcorneal oxygen therapy using humidified oxygen at a flow rate that ranged from 1 to 3 l/minute. RESULTS: All three patients had a dramatic reduction in their intraocular pressure within hours of receiving oxygen therapy. No complications were associated with the oxygen therapy. CONCLUSION: Transcorneal oxygen therapy can reduce intraocular pressure in patients with glaucoma from sickle cell hyphema. Further study is warranted to evaluate this new therapy.- - - - - - - - - - ranking = 1.5keywords = pressure (Clic here for more details about this article) |
7/56. Transient intraocular pressure elevation after trabeculotomy and its occurrence with phacoemulsification and intraocular lens implantation.PURPOSE: To elucidate the characterization of intraocular pressure (IOP) spike after trabeculotomy, and after the combined procedure of phacoemulsification and aspiration (PEA) and intraocular lens (IOL) implantation. methods: Included in this study were 39 patients (53 eyes) with primary open-angle glaucoma with IOPs uncontrolled even with anti-glaucoma medication. We conducted a retrospective study for the following two groups: patients who underwent trabeculotomy alone (25 eyes) and patients undergoing trabeculotomy combined with PEA and implantation of an IOL (28 eyes). RESULTS: In 7 (28%) of the 25 eyes after trabeculotomy alone and 7 (25%) of the 28 eyes after the combined procedure, transient IOP elevation was found postoperatively. The incidence of hyphema-related IOP spike was significantly higher in eyes after trabeculotomy alone (16%) than after the combined procedure (0%). After removal of the blood present in the anterior chamber in eyes with hyphema-related IOP spikes, the IOP levels were well controlled. CONCLUSIONS: hyphema-related IOP spike is one of the common complications in eyes after trabeculotomy alone, and the combined procedure decreases the incidence of this complication. It is thought that removal of prolonged massive hyphema is effective as treatment for hyphema-related IOP spike.- - - - - - - - - - ranking = 2.5keywords = pressure (Clic here for more details about this article) |
8/56. 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 = 0.5keywords = pressure (Clic here for more details about this article) |
9/56. Hemorrhagic Descemet's membrane detachment as a complication of deep sclerectomy: a case report.PURPOSE: To report a case that developed hemorrhagic Descemet's membrane detachment after deep sclerectomy. PATIENT AND methods: Case report. A 63-year-old diabetic patient suffering from uncontrolled chronic open-angle glaucoma with full medication, underwent an uneventful deep sclerectomy operation combined with intraoperative mitomycin-C. RESULTS: On the second postoperative day, a hemorrhagic Descemet's membrane detachment (HDDM) was observed. The hemorrhage showed rapid absorption rate during the first two weeks along with reduction of the HDDM. After this period of time the rate of blood absorption was decreased. The Descemet's membrane reattached completely six months after surgery without any intervention but a paracentral corneal scar was present. The bleb was not functionally impaired during the whole postoperative period, and intraocular pressure remained stable at the level between 12 and 15 mmHg without medication. CONCLUSION: Hemorrhagic Descemet's membrane detachment should be considered as a potential complication of deep sclerectomy.- - - - - - - - - - ranking = 0.5keywords = pressure (Clic here for more details about this article) |
10/56. An unusual case of uveitis-glaucoma-hyphema syndrome.PURPOSE: To report a case of uveitis-glaucoma-hyphema (UGH) syndrome in which anterior chamber paracentesis led to the diagnosis of sickle cell trait. DESIGN: Observational case report. methods: A 43-year-old Cuban pseudophakic male was seen multiple times over a 3-year period complaining of floaters and blurry vision in his left eye. He was noted to have an inferotemporally displaced posterior chamber intraocular lens and recurrent microhyphemas with elevated intraocular pressure (IOP) readings between 29 and 46 mm Hg with each episode. He was diagnosed with UGH syndrome. Posterior chamber intraocular lens explantation and anterior chamber washout was performed. The aqueous fluid was submitted for cytopathologic examination. RESULTS: Postoperatively, the patient's symptoms resolved and he had no further hemorrhages or elevated IOP readings. Cytopathology of the aspirate revealed sickled red blood cells. CONCLUSIONS: Microscopic examination of aqueous fluid can be a valuable tool in diagnosing ophthalmic manifestations of systemic disease.- - - - - - - - - - ranking = 0.5keywords = pressure (Clic here for more details about this article) |
