We present a case of retinitis pigmentosa with vitreoretinal traction-associated retinal detachment. The retinal detachment was detected in the nasal periphery. No retinal breaks and no active vascular leakage were observed by fundus scopy and fluorescein angiography, respectively. However, 8 months later, the tractional retinal detachment was spontaneously resolved with posterior vitreous deta...

OBJECTIVE To document the spontaneous resolution of retinal detachment developing after macular hole surgery. METHODS We identified all patients who developed a postoperative retinal detachment after undergoing macular hole surgery at Washington University School of Medicine, St Louis, Mo; the surgery was performed by one of us (L.V.D.P. or H.J.K.) between 1991 and 1996. RESULTS Six of 73 e...

Between 1975 and 1989, 11 eyes were treated for retinal detachments with both peripheral and full thickness macular breaks. Long term retinal reattachment was dependent on successful closure of peripheral retinal breaks. Direct treatment of the macular break was necessary in only one case, which redetached 3 months after vitrectomy. Vitrectomy is not the initial treatment of choice for uncompli...

the doruneh fault is one of the longest and most prominent faults in iran. however, only two recorded historical earthquakes with magnitudes more than 7 might be related to this fault. for getting more information on this fault more investigation in different fields are required. fault displacement is one of the most important parameters needed to explore the fault activity. in this study, with...

For a graph G, a detachment operation at a vertex transforms the graph into a new graph by splitting the vertex into several vertices in such a way that the original graph can be obtained by contracting all the split vertices into a single vertex. A graph obtained from a given graph G by applying detachment operations at several vertices is called a detachment of graph G. We consider a detachme...

(paper pages 133-156) zagros active fold-thrust belt lies on the northern margin of the arabian continental crust it is a young fold-thrust mountain belt currently shortening, thickening and uplifting as a result of the collision of the arabian and iranian plates. rethickening of crust during collisional orogenies could have been carried out by reversal of fault motion along the mesozoic normal...

The relationship between retinal detachment and posterior lens capsule rupture in pseudophakic patients was studied. Records of patients with pseudophakic retinal detachment who were admitted to Siriraj Hospital from 1992 to 2004 were reviewed. The patients were divided into 2 main groups: 1) The study group (pseudophakic retinal detachment) 79 eyes (78 cases) which was subdivided into group 1a...

the nnw-trending dena fault, with 140 km length, cuts the major structures of zagros fold-thrust belt in borujen region. the fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. this study presents a new interpretation for the kinematics of dena fault based on field evidence....

purpose : evaluating the effects of memantine on visual function after scleral buckling for rhegmatogenous retinal detachment (rrd) methods : in a double blind prospective randomized clinical trial, 61 patients with clinical diagnosis of less than 4 weeks macula-off rrd who had successful scleral buckle surgery had been selected and divided into two randomized groups. thirty of them received 5 ...
