PURPOSE This study investigates the efficacy of an intravitreal gas injection in inducing a posterior vitreous detachment (PVD) in patients with clinically significant diabetic macular edema refractory to laser therapy. METHODS A local ethics committee-approved technique of an intravitreal injection of pure perfluoropropane gas (C(3)F(8)) was performed for all participants. After a period of ...

Case 1 A 51-year-old diabetic visited us for diabetic retinopathy screening. Left eye fundus examination was limited due to asteroid hyalosis (AH) [Fig. 1a]. Optical coherence tomography (OCT) of left eye demonstrated asteroid bodies with posterior vitreous detachment (PVD) [Fig. 1b]. Left eye OCTA revealed multiple black areas in all slabs resembling capillary drop out areas [Fig. 1c-e]. The b...

BACKGROUND To describe the prevalence and associations of posterior vitreous detachment (PVD) in a rural adult Chinese population. METHODS All eligible subjects were requested to carry out a comprehensive eye examination; PVD was a pre-specified outcome variable and was determined via biomicroscopical examination (slit-lamp biomicroscopy) with a +90-D preset lens after mydriasis. Prevalence w...

Multiple posterior segment complications can occur after LASIK. Posterior vitreous detachment, macular holes, retinal hemorrhages, retinal detachment, and several other complications have been described. A case of posterior vitreous detachment with epiretinal membrane in a young adult after LASIK is reported. LASIK surgeons must be aware of the possibility of posterior segment complications aft...

Despite recent anatomical successes of surgical treatment for rhegmatogenous retinal detachment (RRD), reattachment fails in 1.1-2.5% of cases [1-3]. In addition, even in cases of reattachment, some patients continue to show poor functional results [1, 2]. Prevention of RRD is therefore undoubtedly desirable. We retrospectively examined subjective signs in patients who underwent surgery for RRD...

Ocriplasmin (Jetrea®) is a recombinant protease used to treat vitreomacular traction. To gain insight into vitreoretinal observations reported after ocriplasmin treatment, we have developed an in vivo porcine ocriplasmin-induced posterior vitreous detachment (PVD) model in which we investigated vitreoretinal tissues by optical coherence tomography, histology, and cytokine profiling. Eight weeks...

Vitreous floaters are one of the most common complain ophthalmological patients. The aetiology includes pathological process (vitreous haemorrhages, injuries, diabetics or uveitis) and also natural age-related changes in vitreous body. Diagnosis treatment depends on severity symptoms. Process posterior detachment requires particularly careful monitoring, because potential complications such as ...

Herein we present the spectral-domain optical coherence tomographic (SD-OCT, Heidelberg Spectralis; Heidelberg Engineering, Heidelberg, Germany) image of an 80-year-old male patient with partial posterior vitreous detachment (PVD). Tractional forces from the vitreous body pull retinal layers by means of vitreoretinal adhesions.1,2 This high-resolution SD-OCT image illustrates how traction eleva...
