Aims: To compare the pressure inside and outside the pig eye in relation to the location of cannulation for the injection of liquid into the anterior or vitreous chamber. Method: Eleven enucleated pig eyes were used. 46 measurements of intraocular pressure IOP were taken with a Perkins tonometer when the eye was cannulated in the anterior chamber. 49 measurements were taken when the eye was can...

In 3 cases of keratoplasty in aphakic eyes 4--8 months after surgery a gradual flattening of the anterior chamber was observed. During the initial postoperative months there was no suggestion of any impending complication. No synechiae at the anterior chamber angle were present, the anterior vitreous face had remained intact without being in contact with the posterior corneal surface, and the i...

Total superoxide dismutase (SOD) activity was examined in the anterior humor of 32 diabetic patients and 34 nondiabetic controls during cataract extraction. Median age (95% confidence interval) was 77.5 yr (73.3-81.0) and 79.3 yr (76.0-83.2), respectively. The SOD activity also was examined in posterior vitreous sampled peroperatively in 10 diabetics with proliferative retinopathy and post-mort...

PURPOSE To investigate the contribution of the individual ocular components, i.e. anterior chamber depth, lens thickness and vitreous chamber depth, to total axial length in patients with esotropic amblyopia. METHODS The study population consisted of 74 children, aged between 5 and 8 years: thirty-seven patients with esotropic amblyopia and 37 healthy volunteers (control group). The participa...

PURPOSE To investigate the distribution of axial length, anterior chamber depth, lens thickness, vitreous chamber depth, and central corneal thickness in children at different age groups. METHODS We studied 364 eyes in 182 children with ages between 1 and 12 years. Axial length, anterior chamber depth, lens thickness, and vitreous chamber depth were measured by ultrasound biometry. Central co...

purpose: to describe the association between optic disc traction and non-arteritic anterior ischemic optic neuropathy (naion). methods: eighty three eyes of 83 patients with naion were evaluated by optical coherence tomography (oct) for detecting vitreous adhesion to the optic nerve head with separation from adjacent retina (partial posterior vitreous detachment). those who were negative for su...

We have shown previously that FGF induces lens epithelial cells in explant culture to proliferate, migrate and differentiate into fibre cells in a progressive concentration-dependent manner. In situ, these processes occur in a distinct anterior-posterior pattern in clearly defined regions of the lens. Thus anterior-posterior differences in the bio-availability of FGF in the lens environment may...

BACKGROUND Atypical serous chorioretinopathy can present with symptoms similar to those of other pachychoroid diseases; however, a proper differential diagnosis will prevent unnecessary intensive treatments. To this end, we report on the shallowness of anterior chamber and transitory anterior vitreous cells in a patient with atypical severe serous retinal detachment. CASE PRESENTATION A 42-ye...

BACKGROUND To assess the sensitivity, specificity, positive predictive value and negative predictive value of anterior chamber tap for the diagnosis of bacterial endophthalmitis on a population with high prevalence. METHODS Retrospective, single centre, case series study. We reviewed all medical records with clinical diagnosis of bacterial endophthalmitis in our hospital from January 1st, 200...

Vitreous loss is a serious complication of cataract surgery. Following vitreous loss it is common practice to perform a primary implantation of an anterior chamber lens (AC-IOL). We retrospectively analysed 642 consecutive cases of cataract extraction performed between 1983 and 1986 with special attention to those patients in whom vitreous loss occurred and an AC-IOL was placed. There were 27 s...
