A primate eye affected by postoperative infectious endophthalmitis was studied early in the course of the disease. Retinal perivasculitis, vitreoretinal adhesions along the inflamed vessels, and traction of the partially separated posterior vitreous on the retina at the adhesion sites were observed. It is suggested that such vitreoretinal junction pathology may be responsible for the developmen...

Snowflake Vitreoretinal Degeneration (SVD) is associated with the R162W mutation of the Kir7.1 inwardly-rectifying potassium channel. Kir7.1 is found at the apical membrane of Retinal Pigment Epithelial (RPE) cells, adjacent to the photoreceptor neurons. The SVD phenotype ranges from RPE degeneration to an abnormal b-wave to a liquid vitreous. We sought to determine how this mutation alters the...

PURPOSE To describe enhanced vitreous imaging for visualization of anatomic features and microstructures within the posterior vitreous and vitreoretinal interface in healthy eyes using swept-source optical coherence tomography (SS-OCT). The study hypothesis was that long-wavelength, high-speed, volumetric SS-OCT with software registration motion correction and vitreous window display or high-dy...

PURPOSE To investigate vision-related quality of life (VR-QOL) in patients undergoing vitrectomy for various vitreoretinal disorders and to evaluate the relationship between VR-QOL and visual function. METHODS The study included 100 normal control subjects and 299 patients with various vitreoretinal disorders including proliferative diabetic retinopathy (PDR), diabetic macular edema (DME), br...

Objective: The evaluation of intraocular pressure (IOP) after vitreoretinal surgery is critical to ensure the normal function of the eye. The purpose of this study was to determine the incidences and risk factors of early postoperative IOP elevation after vitreoretinal surgery. Method: Data were collected and retrospectively analyzed from 150 patients (150 eyes) who received vitreoretinal surge...

objective: to determine the sensivity and specifity of ocular ultrasonography in detecting vitreoretinal lesion prior to deep vitrectomy in patients with opaque media. method: the hospital records of patients undergoing deep vitrectomy in a defined period at shiraz khalili hospital were reviewed. sonographic reports given by a sonologist and operation reports given by a vitreoretinal fellowship...

IMPORTANCE Intraocular lymphomas represent a diverse group of hematologic malignant neoplasms involving different tissues within the eye. Predominant involvement of the retina and vitreous without uveal infiltration in systemic lymphoma, mimicking a primary vitreoretinal lymphoma, is extremely rare. Our study emphasizes the importance of systemic evaluation in addition to central nervous system...

BACKGROUND The vitreoretinal interface is the border of the cortical vitreous and the inner surface of the retina. The adhesion of the cortical vitreous to the ILM, namely vitreoretinal adhesion, involves a series of complex molecular adhesion mechanisms and has been considered as an important pathogenic factor in many vitreoretinal diseases. The presence of type VI collagen at the vitreoretina...

OBJECTIVES To evaluate the demographics, surgical indications and clinical results of patients with repositioned or explanted intraocular lens (IOL) in a tertiary referral eye hospital. MATERIALS AND METHODS Forty-eight eyes of 48 patients that underwent surgery to exchange or reposition the IOL at Ulucanlar Eye Training and Research Hospital between 2009 and 2013 were included in the study. ...

PURPOSE Geographic atrophy (GA) is the end-stage manifestation of atrophic age-related macular degeneration (AMD). The disease progresses slowly over time, eventually causing loss of central vision. Its cause and pathomechanism are not fully known. Previous studies have suggested that vitreoretinal traction (VRT) may contribute to the progression of neovascular AMD. The aim of this study was to...
