1/53. Production of anterior segment ischemia.Anterior segment ischemia changes can occur without detachment of any muscles. The most common cause of such ischemic changes of the anterior segment is the removal of too many rectus muscles in one operation. Twenty dog eyes and eight monkey eyes were subjected to the disinsertion and detachment of various combinations of extraocular muscles. They were sacrificed at intervals from 30 to 90 days. During the observation period, they were observed for gross and slit lamp changes. The enucleated eyes were studied microscopically for signs of ischemic and necrotic changes. Two patients who were studied, observed, and treated for anterior segment ischemia following muscle surgery are described. The changes which occur after muscle surgery are extensive and include corneal edema, cataract, chemosis, corneal changes, decreases in intraocular pressure, decreases in outflow or glaucoma and frank necrosis. The variables which lead to this reaction is described in detail. Also, some unanswered queries, such as the duration of the reaction and the time interval of the reaction after multiple muscle surgeries, are discussed.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
2/53. Early acute aseptic iritis after cataract extraction.Severe iritis which occurs within the first five days after cataract extraction may be categorized as (1) bacterial endophthalmitis, (2) toxic iritis, or (3) aseptic iritis. These entities can sometimes be distinguished because of their clinical features. If bacterial endophthalmitis is suspected, anterior chamber paracentesis should be considered and appropriate antibiotic treatment should be initiated. Acute iritis may result from the introduction of toxic agents into the eye, and may follow the use of products sterilized with ethylene oxide. Early acute aseptic iritis probably occurs more often than has previously been recognized. Response to intensive anti-inflammatory treatment is usually prompt and dramatic. The judicious use of cryoextraction and the careful manipulation of intraocular tissues may minimize the incidence and the severity of postoperative inflammation.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
3/53. Prolonged prodrome, systemic vasculitis, and deafness in Cogan's syndrome.Cogan's syndrome is a rare, multisystem disease which occurs predominantly in children and young adults. It was originally described as the combination of interstitial keratitis and audiovestibular disturbance, but other forms of ocular disease, as well as systemic vasculitis, have since been recognised as part of the syndrome. diagnosis can be difficult if the various manifestations occur separately, but early recognition is important because prompt treatment may prevent deafness. Two cases are presented here illustrating the features of this disease, and providing histological evidence of systemic vasculitis in both.- - - - - - - - - - ranking = 10.475244981161keywords = keratitis, ocular (Clic here for more details about this article) |
4/53. Is Posner Schlossman syndrome benign?PURPOSE: To determine the clinical course of patients with Posner Schlossman syndrome (PSS). DESIGN: Retrospective noncomparative case series. PARTICIPANTS: Fifty-three eyes of 50 patients. methods: The case notes of all patients with PSS seen at the uveitis Clinic of singapore National eye Centre were reviewed for evidence of glaucoma damage and risk factors. MAIN OUTCOME MEASURES: Visual field and optic disc changes consistent with glaucoma. RESULTS: There were 28 men and 22 women, and their mean age at onset was 35 years. Fourteen eyes (26.4%) were diagnosed to have developed glaucoma as a result of repeated attacks of PSS. patients with 10 years or more of PSS have a 2.8 times higher risk (95% confidence interval 1.19-6.52) of developing glaucoma compared with patients with less than 10 years duration of the disease. Nine eyes (17%) underwent glaucoma filtering surgery with antimetabolites. Their postoperative follow-up ranged from 15 to 50 months (mean, 37 months). Four eyes continued to have episodes of iritis after surgery, and one of these eyes had elevated intraocular pressure during the event. CONCLUSIONS: A significant number of patients with PSS have glaucoma develop over time, and they need to have their optic disc appearance and visual fields carefully monitored.- - - - - - - - - - ranking = 0.5keywords = ocular (Clic here for more details about this article) |
5/53. Diffuse lamellar keratitis associated with iritis 10 months after laser in situ keratomileusis.A 35-year-old man developed diffuse lamellar keratitis (DLK) 10 months after laser in situ keratomileusis (LASIK). The DLK was associated with acute iritis, not with manipulation of the LASIK flap or epithelium. This case supports the hypothesis that DLK is a nonspecific inflammatory response of the cornea rather than a specific agent causing the syndrome.- - - - - - - - - - ranking = 49.876224905806keywords = keratitis (Clic here for more details about this article) |
6/53. Placement of a collagen glaucoma drainage device to control intraocular pressure and chronic iritis secondary to juvenile rheumatoid arthritis.A patient with juvenile rheumatoid arthritis and chronic iritis is reported with intraocular pressure near 30 mm Hg and previous episodes of intraocular pressure as high as 50 mm Hg despite maximally tolerated medical therapy. Because of the potential risk involved with a full-thickness filtration procedure, it was decided that a nonpenetrating deep sclerectomy would be appropriate, followed by placement of a collagen glaucoma drainage device to maintain aqueous outflow. Immediately postoperatively, intraocular pressure was stabilized. At 24 months postoperatively, intraocular pressure was well controlled at 15 mm Hg with patient receiving only Lotemax. No significant complications were noted at any point in the postoperative course. Because of the patient's predisposition for serious complications frequently associated with trabeculectomy, nonpenetrating deep sclerectomy with the collagen glaucoma drainage device was an effective alternative for this patient.- - - - - - - - - - ranking = 4keywords = ocular (Clic here for more details about this article) |
7/53. Peripheral keratitis associated with chronic myelomonocytic leukemia.PURPOSE: To describe a case of peripheral keratitis in a patient with an acute exacerbation of chronic myelomonocytic leukemia (CMML). METHOD: Case report and review of the literature. RESULTS: This is the second reported case of peripheral keratitis in a patient with CMML. The previously reported patient presented with peripheral keratitis that led to the diagnosis of leukemia. Our patient had an established diagnosis of CMML, and peripheral keratitis occurred during an acute exacerbation of his chronic leukemia. The keratitis resolved with topical corticosteroids in our patient. CONCLUSION: leukemia should be included in the differential diagnosis of peripheral keratitis. Elevated white blood cell count with abnormal differential in a patient with peripheral keratitis may help to establish a diagnosis of leukemia or identify an acute exacerbation of chronic leukemia.- - - - - - - - - - ranking = 109.72769479277keywords = keratitis (Clic here for more details about this article) |
8/53. An unusual case of late ocular changes after lightning injury.We describe a case of late ocular changes after lightning injury. One year after the injury, complete ankyloblepharon, severe dry eye, corneal opacity, healed iritis and mature cataracts were noted in both eyes of the patient.- - - - - - - - - - ranking = 2.5keywords = ocular (Clic here for more details about this article) |
9/53. Ocular manifestations of electrical injury: a case report and review of the literature.PURPOSE: To report a case of electrical shock resulting in multiple ocular manifestations, including anisocoria, acute bilateral iritis, bilateral cataracts, and macular cyst formation, and to provide a review of the literature on electrically induced ocular injuries. methods: Case report and review of the literature. RESULTS: The case presented demonstrates a sequential occurrence of anisocoria, bilateral cataract formation, iritis, and macular cyst formation, with resolution following medical and surgical treatment. CONCLUSIONS: Electrically induced injuries can have many ocular manifestations that may occur simultaneously or sequentially, occasionally occurring later than the inciting event. The most common ocular finding is cataract formation.- - - - - - - - - - ranking = 2keywords = ocular (Clic here for more details about this article) |
10/53. Endogenous pneumococcal endophthalmitis followed by pneumococcal-induced uveitis.BACKGROUND: We describe the case of a fulminant bilateral endophthalmitis occurring in a patient, who had 9 years earlier a splenectomy for an idiopathic thrombocytopenic purpura. history AND SIGNS: A 40-year-old woman, back from a trip to morocco, presented with high fever, rapid decrease in visual acuity and loss of consciousness. Medical examination revealed a pneumococcal meningitis and bilateral endophthalmitis. THERAPY AND OUTCOME: endophthalmitis was treated with local and intravitreal antibiotics injections (vancomycin and amikacin). Repeated parabulbar betamethasone injections were performed. Intravenous (iv) methylprednisolone pulses were followed by oral steroid therapy while systemic antibiotics were given (ceftriaxone and vancomycin). In spite of this therapy, fundus examination was impossible because the anterior chamber was filled with fibrin. A cataract developed with severe vitritis and we could observe a progressive narrowing of the anterior chamber. The patient underwent a bilateral vitrectomy and lensectomy. The retina had no lesion. No bacteria were found in the vitreous culture. Evolution was characterized by an increased ocular pressure due to anterior synechiae. visual acuity remained under 1/10. The severe ocular inflammation could be the result of a mixed mechanism including an infectious followed by a severe immune response against bacterial components. CONCLUSIONS: This case report is rare. To our knowledge, only 3 similar cases have been reported in the literature.- - - - - - - - - - ranking = 1keywords = ocular (Clic here for more details about this article) |
