The purpose of this study was to review our clinical experience with 132 idiopathic orbital inflammation cases seen between 1971 and 1994. Clinical charts of the patients were evaluated retrospectively. Patient age ranged from 5 to 80 (mean 46.5) years. The follow-up period was between 6 to 172 (mean 42.8) months. Proptosis (82%), motility restriction (54%), visual acuity loss (38%) were the three more common presenting signs. The diagnosis was made by open biopsy in 96 cases and clinically in 36 cases. Radiologic patterns of involvement were available for 84 cases. Diffuse inflammatory disease (40 cases) was the most frequent radiologic pattern followed by myositis (21 cases) and dacryoadenitis (14 cases). Focal encapsulated mass (5 cases), Tolosa-Hunt syndrome (2 cases) perineuritis (1 case) and periscleritis (1 case) were the other types of orbital pseudotumors. The response to treatment was known for 60 of the 84 radiologically classified cases. High-dose oral corticosteroid treatment was successful in 35 out of 60 (58.3%) cases and radiotherapy in 9 out of 14 (64.3%) cases resistant to corticosteroids. One resistant case responded to cyclophosphamide and 2 cases with focal mass lesions were treated with orbitotomy. Four additional cases had spontaneous remission. Overall, 51 out of 64 patients (79.7%) had an eventual good outcome. In conclusion, we found open biopsy to be a safe and reliable procedure in orbital pseudotumors with the exclusion of acute phase cases. The success rate of treatment for this group of orbital disorders is high with the exception of certain disease patterns.
Oculogyric crisis is an acute dystonic reaction of the ocular muscles characterized by bilateral dystonic elevation of visual gaze lasting from seconds to hours. This reaction is most commonly explained as an adverse reaction to drugs such as antiemetics, antipsychotics, antidepressants, antiepileptics, and antimalarials. Although the incidence of metoclopramide-induced acute dystonic reactions has been reported as 25% in children, there have been few published cases on oculogyric crisis in general. It is important to be able to recognize this ocular side effect because, without a thorough patient history, symptoms can be confused with other diseases such as versive seizures, paroxysmal tonic upward gaze, and encephalopathy. In this paper, we report a case of oculogyric crisis induced by metoclopramide.
Asteroid hyalosis may be found together with systemic diseases and such patients must be evaluated systematically for diabetes mellitus, hypertension and hyperlipidemia. Asteroid hyalosis can also cause artefactual lowering of axial length measurement, leading to significant error in calculations of intraocular lens power. This must be kept in mind before cataract surgery.
BackgroundThe aim of this study was to compare the effect of W-shaped skin (WS) and linear skin (LS) incisions on cutaneous scar tissue formation in patients who have undergone bilateral external dacryocystorhinostomy.MethodsSixteen patients (14 females and two males) with acquired bilateral nasolacrimal duct obstruction were included in this prospective, interventional comparative study. LS incision was applied to one side and WS skin incision to the other side. The skin incisions were assessed 6 months after each procedure by the patients themselves and by two ophthalmologists who were unaware of the skin incision shape and side. Scar tissue that was not recognized under the same light conditions and in the same room from a 100 cm distance was recorded as grade 1. Minimally visible scar tissue was assessed as grade 2, moderately visible scar tissue as grade 3, and easily visible scar tissue as grade 4.ResultsThe mean scar assessment scores recorded by the first ophthalmologist were 2.50±0.82 for the LS group and 1.25±0.45 for the WS group (P<0.001). The second ophthalmologist’s assessment scores were 2.25±0.86 for the LS group and 1.25±0.45 for the WS group (P<0.001). The mean patient self-assessment score for the incision scars was 2.44±1.03 for the LS group and 1.56±0.73 for the WS group (P<0.001).ConclusionCompared with LS incision, WS incision resulted in less cutaneous scar tissue formation in patients who have undergone bilateral external dacryocystorhinostomy.
Retinal atrophy is well known in adult-onset multiple sclerosis but remains unexplored in children. We aimed to determine retinal nerve fiber layer thickness and macular volume in pediatric patients, with and without optic neuritis and their relations with visual evoked potentials. We also examined macular volume changes at month 12. Retinal nerve fiber layer thickness of all quadrants and macular volume were measured in 28 relapsing remitting multiple sclerosis eyes and 30 control eyes using optical coherence tomography and were found reduced in patients compared with controls. This reduction was more prominent in eyes with longer time interval from optic neuritis. Retinal nerve fiber thickness was lower in eyes with delayed visual evoked potentials. Visual evoked potential amplitudes were reduced in affected eyes compared to patients without optic neuritis. Macular volume reduced nonsignificantly in patients at month 12. Retinal atrophy occurs in pediatric multiple sclerosis, and previous optic neuritis accelerates this atrophy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
