1/16. Ultrasound biomicroscopy in the diagnosis and management of pars planitis caused by caterpillar hairs.PURPOSE: To report the use of ultrasound biomicroscopy in the detection of caterpillar hairs in the pars plana in a patient with unilateral pars planitis. METHOD: Ultrasound biomicroscopic imaging of the anterior segment of the eye. RESULTS: Ultrasound biomicroscopy located a hair in the posterior chamber at the first visit and five more in the pars plana 1 month later. This finding was confirmed intraoperatively. CONCLUSION: Ultrasound biomicroscopy is useful in the diagnosis and management of unilateral pars planitis of uncertain cause.- - - - - - - - - - ranking = 1keywords = planitis, par (Clic here for more details about this article) |
2/16. vitreous hemorrhage is a common complication of pediatric pars planitis.OBJECTIVE: To report the prevalence of vitreous hemorrhage in pars planitis and to compare the prevalence of hemorrhage for children and adults with the disease. DESIGN: A retrospective, cross-sectional observational study. PARTICIPANTS: One hundred eighteen consecutive patients with pars planitis who were evaluated at the oregon health and science University uveitis Clinic between September 1985 and April 2000. METHOD: A review of clinical records. MAIN OUTCOME MEASURES: For all patients, we recorded presence or absence of vitreous hemorrhage, as well as laterality and cause. Children were defined as being age 16 years or younger at diagnosis, and adults were defined as being aged 17 years or older at diagnosis. RESULTS: Fourteen percent of patients with pars planitis experienced vitreous hemorrhage. persons with hemorrhage were significantly younger at the time of disease diagnosis than persons without hemorrhage (P = 0.040). The difference in prevalence of vitreous hemorrhage between children (28%) and adults (6%) was statistically significant (P = 0.003). The difference in prevalence of hemorrhage as a presenting feature between children (20%) and adults (1%) was also statistically significant (P = 0.001). CONCLUSIONS: Children with pars planitis are more likely than adults to experience vitreous hemorrhage. pars planitis should be considered in the differential diagnosis of pediatric vitreous hemorrhage.- - - - - - - - - - ranking = 1.288612095138keywords = planitis, par (Clic here for more details about this article) |
3/16. Lower eyelid herniation of orbital fat may complicate periocular corticosteroid injection.PURPOSE: To report a case of lower eyelid herniation of orbital fat occurring after periocular corticosteroid injection. DESIGN: Interventional case report. methods: A 44-year-old man with asymmetrical pars planitis complicated by right cystoid macular edema was treated with multiple right orbital floor injections of triamcinolone through the lower eyelid. RESULTS: Right lower eyelid orbital fat herniation occurred during the course of the treatment. CONCLUSION: A herniation of orbital fat may complicate the injection of corticosteroid through the lower eyelid.- - - - - - - - - - ranking = 0.143179121682keywords = planitis, par (Clic here for more details about this article) |
4/16. Inflammatory bowel disease (Crohn's disease) in a Spanish patient with pars plana exudates: report of a new case and review of the literature.Several ocular manifestations have been found in Crohn's disease patients, most often affecting the anterior segment. This paper presents the case of a young woman with pars plana exudates in whom Crohn's disease was later diagnosed. To the authors' knowledge, this is only the second report of Crohn's disease and concomitant pars plana exudates.- - - - - - - - - - ranking = 0.42277580972396keywords = par (Clic here for more details about this article) |
5/16. Peripheral retinoschisis and exudative retinal detachment in pars planitis.PURPOSE: To review and describe bullous retinoschisis and exudative retinal detachment in patients with pars planitis. methods: Retrospective, multicenter study of patients with pars planitis who presented with retinoschisis and exudative retinal detachments. RESULTS: The authors describe 13 eyes of 9 patients with pars planitis who presented with inferior peripheral retinoschisis and/or exudative retinal detachment. Four patients were male; five were female. patients' ages ranged from 8 years to 35 years (median, 12 years). The follow-up interval ranged from 1 month to 10 years (median, 4 years). These peripheral retinal elevations had a tendency to remain stable, although those with telangiectatic vessels or vasoproliferative tumors occasionally demonstrated an increase in accumulation of exudate. Treatment of such eyes with cryotherapy, or low-dose plaque radiotherapy, resulted in vasoproliferative tumor and telangiectatic vessel regression, absorption of the hard exudate, and resolution of the retinal elevation in four of five eyes. One patient had spontaneous regression of the retinoschisis cavity over a 4-year period. CONCLUSION: patients with pars planitis may present with bullous retinoschisis and/or exudative retinal detachment. These findings may be related to a Coats disease-like vascular response (telangiectatic vessels and vasoproliferative tumors) secondary to chronic inflammation. Treatment of the vascular leakage tended to result in resolution of the detachment and/or schisis.- - - - - - - - - - ranking = 1.145432973456keywords = planitis, par (Clic here for more details about this article) |
6/16. An immunohistochemical study of the 'snowbank' in a case of pars planiti.PURPOSE: To characterize the extracellular matrix and cellular components of a 'snowbank' removed during vitreous surgery for treatment of retinal detachment complicating pars planitis. methods: The 'snowbank' was examined using immunohistochemical techniques and a panel of monoclonal and polyclonal antibodies directed against glial fibrillary acidic protein (GFAP), cytokeratin, alpha smooth muscle actin, tenascin, laminin, fibronectin, and collagen types I, II, and III. RESULTS: The 'snowbank' was acellular except on the uveal side where there were cytokeratin-positive retinal pigment epithelial cells. There were no cells positive for the glial cell marker GFAP and the myofibroblast cell marker alpha smooth muscle actin. The extracellular matrix of the 'snowbank' contained tenascin and collagen types I, II, and III. There was no immunoreactivity for laminin and fibronectin. CONCLUSION: These results on the immunohistochemical components of the 'snowbank' may be useful in clarifying the nature of the chronic inflammatory process in pars planitis. They indicate extensive tissue repair and remodeling, leading to major loss of function.- - - - - - - - - - ranking = 0.56820878317997keywords = planitis, par (Clic here for more details about this article) |
7/16. Valsalva retinopathy: diagnostic challenges in a patient with pars-planitis.PURPOSE: To describe a case of Valsalva retinopathy in a patient with pars-planitis and to discuss its management. methods: We present a case of a 19-year-old male with a six-month history of bilateral intermediate uveitis, referred for evaluation of recent-onset spontaneous bilateral vitreous hemorrhages. Clinical evaluation and fluorescein angiography were negative for the presence of neovascularization. On closer questioning the patient revealed that he had his most recent symptoms after heavy weight lifting. RESULTS: The patient was instructed to avoid heavy weight lifting. Over the next two months, vitreal hemorrhages had resolved. However, despite the treatment with systemic prednisone, the patient's intermediate uveitis was still active, and cystoid macular edema had developed. Therefore, we proceeded to systemic immunomodulatory therapy, which controlled the inflammation and preserved vision in each eye. CONCLUSIONS: Although a very rare cause, valsalva maneuver should be included in the differential diagnosis of bilateral vitreous hemorrhages. Ophthalmologists should advise patients with known eye problems that can predispose to vitreal hemorrhages to refrain from it.- - - - - - - - - - ranking = 0.71589560841001keywords = planitis, par (Clic here for more details about this article) |
8/16. pars planitis in father and son.The authors examined a family in which father and son presented with pars planitis. Both of them and the paternal grandparents were HLA typed; no association between hla antigens and pars planitis was found.

9/16. Lens implant surgery in pars planitis.Intraocular lens (IOL) implantation is usually contraindicated in eyes with active inflammation, but patients with "burned-out" pars planitis also may be considered as candidates. Fifteen of 16 eyes in eight patients underwent extracapsular cataract extraction (ECCE) with posterior chamber IOL (PC IOL) implantation combined with pars plana vitrectomy for both cataracts and chronic cystoid macular edema (CME); 60% achieved visual acuity of 20/40 or better. Even with "low-grade" inflammation in these patients, however, a persistent veil of debris accumulated over the posterior and anterior surface of the IOL. One patient (patient 2) required 27 YAG procedures for two eyes, and another required 11 YAG procedures and eventual removal of the IOL. Another patient required surgical "brushing-off" of the IOL and vitrectomy. Even in eyes with "burned-out" uveitis, a continual low-grade inflammation may complicate the use of IOL implantation.- - - - - - - - - - ranking = 0.786358243364keywords = planitis, par (Clic here for more details about this article) |
10/16. Familial pars planitis.pars planitis is an intraocular inflammatory disorder which usually affects children or young adults and is characterized by vitreous cells and debris ('snowballs'), exudate, and 'snowbank' formation along the pars plana, variable periphlebitis, and cystoid macular edema. Although no inheritance pattern has been defined, familial cases of pars planitis have been reported. This report describes pars planitis in two sisters, one of whom had evidence of demyelinating disease at presentation. The literature on familial pars planitis is reviewed. To the author's knowledge this is the first case of familial pars planitis as the presenting sign of possible demyelinating disease.- - - - - - - - - - ranking = 1.288612095138keywords = planitis, par (Clic here for more details about this article) |
