A rare case of unilateral orbital schwannoma arising from the
infraorbital nerve is presented. An excision biopsy with complete
removal of the mass in the inferior orbit was performed. A
definitive diagnosis was made on histopathological examination.
The clinical and histological features of schwannoma are
discussed. A need for early removal of such tumors is
recommended to prevent complications.
Sir, Foveoschisis after vitrectomy for myopic macular hole with secondary retinal detachment Macular foveoschisis is a recently identified cause for visual loss in pathological myopia. 1 Factors contributing to foveal splitting include vitreoretinal traction, chorioretinal atrophy, axial elongation, and recently, arteriolar traction. 2,3 We report a foveoschisis that occurred many years after surgery for retinal detachment (RD) associated with a myopic macular hole.
Case reportA 49-year-old lady presented to us with decreased vision OS for 2 months. Best-corrected visual acuities (BCVAs) were 6/12 (À11 þ À2 Â 90) OD and hand motions
The case of a 44-year-old woman who was under treatment for bilateral recurrent anterior uveitis with chronic cystoid macular edema for two and a half years. She presented with an acute visual decline in her left eye, and was found to have a lamellar macular hole in the right eye and a full-thickness macular hole in the left eye. She underwent vitrectomy, internal limiting membrane peeling and perfluoropropane (C(3)F(8)) gas tamponade with simultaneous cataract extraction in the left eye. Her best-corrected visual acuity improved from 4/60 to 6/36 postoperatively, with closure of macular hole. Four months following vitrectomy, she developed cystoid macular edema in the operated eye, with a drop in vision to 6/60. An intravitreal injection of triamcinolone acetonide resulted in recovery of visual acuity 6/24, which was maintained till the last follow-up.
Increased lens thickness in the absence of anterior segment arrest seems to be the major contributing factor for myopia in ROP.This change may be associated with altered neuroectodermal development in ROP.
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.
