Retinal afferent ingrowth to embryonic neural transplants in the adult rat superior colliculus may represent either sprouting of intact axons or the regeneration of transected axons. If ingrowth represents regeneration of damaged retinofugal axons, then lesions that axotomize more retinofugal axons at the transplantation site should induce greater retinal afferent ingrowth. Alternately, if ingr...

Trans-differentiation to a transfer-cell morphology is characterized by the localized deposition of wall ingrowth papillae that protrude into the cytosol. Whether the cortical microtubule array directs wall ingrowth papillae formation was investigated using a Vicia faba cotyledon culture system in which their adaxial epidermal cells were spontaneously induced to trans-differentiate to transfer ...

This is a case report about the anterior segment findings of epithelial ingrowth in a young female patient after penetrating trauma. The patient underwent multiple surgeries after penetrating trauma and epithelial ingrowth was noted on regular follow-up. Epithelial ingrowth was noted along the inner surface of corneal endothelium along with the presence of cysts. These findings suggest that epi...

AIMS/BACKGROUND To correlate the histopathology of an excised choroidal neovascular membrane (CNV) with the clinical and angiographic findings in a 32-year-old woman with pseudotumour cerebri and a peripapillary CNV with subfoveal extension. METHODS The patient's visual acuity was assessed by individuals experienced in low vision refraction and who were not members of the surgical team. The C...

fibrovascular polyps are rare, pedunculated, tumor-like lesions that are usually found in the esophagus; occurrence in the stomach is very rare. to our knowledge, sonographic and ct findings of a fibrovascular polyp in the stomach have never been reported. here, we report a case of a fibrovascular polyp that was identified in the gastric antrum and prolapsed into the duodenal bulb. sonography r...

BACKGROUND We classified iatrogenic retinal break formation during 20-gauge pars plana vitrectomy for proliferative diabetic retinopathy into three types according to the mechanism of development, and evaluated the association of each type with postoperative complications. This is the largest series of such patients published to date. METHODS This was a retrospective comparative study of 760 ...

purpose : to compare postoperative anatomical sclerotomy sites of transconjunctival sutureless vitrectomy (tsv) with conventional 20-gauge vitrectomy methods : in this prospective, nonrandomized study 30 consecutive patients divided in 2 groups: group i, 15 eyes from 15 patients underwent conventional 20-gauge and group ii, 15 eyes from 15 patients underwent tsv (23, 25-gauge) pars plana vitrec...

PURPOSE To investigate the matrix metalloproteinase (MMP) species and their activation associated with the pathogenesis of proliferative diabetic retinopathy (PDR). METHODS Sandwich enzyme immunoassays were used to measure concentrations of MMP-1, -2, -3, -7, -8, -9, and -13 in vitreous samples from patients with PDR and nondiabetic vitreoretinal diseases. To evaluate activation ratios of the...

normal 0 false false false en-us x-none ar-sa microsoftinternetexplorer4 background: to investigate the reasons for p ostvitrectomy diabetic vitreous hemorrhage (pdvh), and to analyze the time of pdvh onset, the treatment of pdvh, the visual outcome of the treatment, and factors that affect visual acuity after treatment. materials and methods: overall, 292 eyes from 236 patients with proliferat...
