PurposeTo compare the structural changes, clinical course, and treatment outcomes of vertical and horizontal vitreomacular traction (VMT) induced impending macular holes (IMHs) and full-thickness macular holes (FTMHs).MethodsIn this retrospective study, 23 and 32 cases of IMHs and FTMHs, respectively, were analyzed. The IMH cases were divided into two subgroups: IMH with and without foveal detachment. Vitreofoveal traction angles (TAs) between the inner retinal surface and posterior hyaloid were measured from horizontal and vertical optical coherence tomography (OCT) images by using the trigonometric function (the angle equals the arctangent of the height over the base) after adjustments for magnification factors...

PURPOSE: This study aimed to evaluate the relationship between macular structural changes and visual prognosis after pars plana vitrectomy (PPV) for proliferative diabetic retinopathy. METHODS: The study included 60 eyes that had undergone PPV. Macular optical coherence tomography (OCT) findings were classified into 5 groups preoperatively and 10 groups postoperatively. Best-corrected visual acuity (BCVA) were analyzed according to pre- and postoperative OCT. RESULTS: From the preoperative OCT, normal fovea with/without traction, normal fovea with preretinal hemorrhage, and tractional retinal detachment involving fovea showed an increase in BCVA after PPV (all p < 0...

Macular hole-associated retinal detachment in high myopia is described as a final stage in progression of myopic traction maculopathy (MTM).(1â€"3) Shimada et al(4) described the progressive stages of MTM from macular retinoschisis to serous retinal detachment in high myopia. Stage 4 MTM is characterised as disappearance of retinoschisis with progression to retinal detachment due to macular hole formation. It is hypothesised that vitreoschisis and abnormal vitreo-retinal interface create the premacular tangential traction...

A 31-year-old man presented to us with diminution of vision in the right eye which he noticed since 10 days, with a visual acuity of hand motions only. On examination, festooned pupil and a complicated cataract were noted with no view of the retina. Ultrasonography of the right eye showed retinal detachment in all quadrants with suspected areas of traction and membranes in the vitreous. Left eye examination revealed a normal anterior and posterior segment. Intraoperatively, he underwent a pars plana lensectomy following which an inferior large retinal haemangioma was noted with dilated and tortuous feeder artery and draining vein...

Inflammation is known to be involved in the progression of diabetic retinopathy. We have recently reported that vitreous levels of IL-4, IL-17A, IL-22, IL-31, and TNFα are higher than the respective serum levels in proliferative diabetic retinopathy (PDR) patients, and that vitreous levels of these cytokines are higher in PDR than in other non-inflammatory vitreoretinal diseases or uveitis associated with sarcoidosis. In the present study, we investigated inflammatory cytokines including Th17 cell-related cytokines in aqueous humor samples obtained from eyes with PDR, and analyzed the association between the aqueous humor and vitreous fluid levels of individual cytokines...

Ocular cysticercosis is a serious condition with a potential for complete vision loss if left untreated. Intravitreal cysticercosis is the most common ocular form of cysticercosis and is associated with retinal detachment, retinal traction, subretinal scarring and vitritis. To the best of our knowledge, there is no report of the occurrence of a live intravitreal cysticercosis with a full thickness macular hole (FTMH) in the literature. We here report a case of live intravitreal cysticercosis with a FTMH along with its management and intraoperative optical coherence tomography features of the live cysticercus...

Technical advancements have substantially extended the indications for surgery in diabetic retinopathy (DR) during the last 40 years, from the traditional indications including non-clearing vitreous hemorrhage, traction retinal detachment (RD), and traction-rhegmatogenous RD, to epiretinal membrane (ERM), vitreomacular traction, diffuse macular edema, neovascular glaucoma, and anterior hyaloid fibrovascular proliferation. The goals of vitreoretinal surgery in DR are multiple: clearing media opacities, release of traction (anteroposterior and/or tangential), segmentation and/or removal of traction bands, peeling of ERMs, hemostasis, laser photocoagulation, and tamponade of retinal breaks with gas or silicone oil...

Almost 25 years after its introduction, optical coherence tomography (OCT) is still a crucial test in the evaluation of patients affected by diabetic retinopathy. In this chapter, the authors provide an extensive overview of the posterior segment pathological changes induced by diabetes, characterized using OCT. OCT plays a key role in diabetic macular edema (DME) as it assesses related retinal changes both in a qualitative (i.e., DME pattern, presence and aspects of cysts, fluid localization, integrity, and reflectivity of retinal layers) and quantitative (i...
