OBJECTIVE To describe the presence of crystalline opacities located at the level of the inner retina in patients with chronic retinal detachment. METHODS We reviewed the clinical records, fundus photographs, and fluorescein angiograms of patients with superficial retinal crystals in the presence of a chronic retinal detachment. RESULTS Eleven eyes in 11 patients with chronic retinal detachm...
RETINAL detachment or the appearance of retinal cysts after the occlusion of large retinal vessels has rarely been described in the literature, although Duke-Elder (1940) mentioned cystic degeneration as invariably following obstruction of the central retinal vein. Norn (1961) described a case of a central retinal cyst which followed a thrombosis of the central retinal vein. Arques (1960) repor...
PURPOSE The present study aims to investigate the number and characteristics of retinal detachment with atopic dermatitis (AD) in these 20 years, and the number of the first visit AD outpatients in almost the same period. METHODS A retrospective review of 101 consecutive surgically treated retinal detachments with AD patients from 1992 to 2011 was conducted. Retinal detachments were divided i...
In a consecutive series of 470 cases of rhegmatogenous retinal detachment 25 (5%) were found to have shifting subretinal fluid (SRF) at the preoperative examination. The study showed that the association between SRF and rhegmatogenous retinal detachment is unusual but not rare. Shifting SRF was most often associated with aphakic and longstanding retinal detachment, and found in cases in which t...
Retinal detachment in adults with posterior segment coloboma is thought to be rhegmatogenous. Vitrectomy techniques are therefore used therapeutically. There is indirect evidence that subretinal fluid in retinal detachment, associated with optic nerve cavitation, is cerebrospinal fluid (CSF). We report 2 pediatric cases, referred for the management of coloboma-related retinal detachment, that p...
I believe this manuscript is well-written and informative. The setting of the manuscript concerning where this clinical investigation was performed, Nagoya, Toyama, or Baltimore, and which institutional review board approve this study were unclear. The author described significantly less incidence of postoperative retinal detachment after 360 prophylactic laser treatment. However, the informati...
INTRODUCTION Rhegmatogenous retinal detachment (RRD) is the most common form of retinal detachment, where a retinal "break" allows the ingress of fluid from the vitreous cavity to the subretinal space, resulting in retinal separation. It occurs in about 1 in 10,000 people a year. METHODS AND OUTCOMES We conducted a systematic review and aimed to answer the following clinical questions: What a...
BACKGROUND The purpose of this study was to evaluate the extension and traction effects of posterior vitreous detachment (PVD) complicated with retinal tears using spectral domain optical coherence tomography (OCT) and B-scan ultrasonography. METHODS Complete ophthalmological examination, B-scan ultrasonography and spectral domain OCT were performed in patients with acute PVD and retinal tear...
PURPOSE To investigate the possibility that cell death in retinal detachment may occur by reactivation of apoptotic programmed cell death mechanisms. METHODS Unilateral retinal detachments were created in adult cats using 0.25% sodium hyaluronate; detached and control retinas were studied at different intervals. Internucleosomal DNA fragmentation (one of the landmarks of apoptosis) was invest...
