    ABSTRACT: Abstract Purpose: The purpose of this study was to measure the pressure difference between the anterior chamber (AC) and the vitreous cavity (VC) in eyes with and without pupillary block. Materials and methods: Seven vitrectomized porcine eyes were used. Infusion pressures of 10-80 mmHg were generated with a vented gas forced infusion system. Measurements of pressure were obtained with digital manometry connected to 25-gauge catheters from the AC and VC simultaneously. After increasing AC pressure to each target pressure, VC pressure was recorded, and vice versa. Inspection was performed with portable slit-lamp biomicroscopy to identify the development of pupillary block at the end of each experiment. Results: When the AC pressure was increased, the VC pressure obtained was similar to the AC pressure in all cases. When the VC pressure increased, the AC pressure obtained was similar to that at a VC pressure of less than 50 mmHg. When the VC pressure was increased rapidly to 60, 70, and 80 mmHg, the AC pressures obtained were 57.6 ± 1.0, 64.0 ± 0.8, and 69.6 ± 2.4 mmHg, respectively. Thus, the VC pressures obtained were 1.5, 5.9, and 9.1 mmHg higher than pressures obtained from AC with target pressures of 60, 70, and 80 mmHg, respectively (p = 0.027, 0.001, and 0.001, respectively). Pupillary block was observed in cases where the VC pressure was increased to more than 50 mmHg. Conclusions: The AC pressure could be significantly lower than the VC pressure in some eyes with pupillary block.

    ABSTRACT: Abstract Purpose: To evaluate the relationship between skin autofluorescence (SAF), which reflects the accumulation of advanced glycation end products (AGEs), and the severity of diabetic retinopathy (DR) in patients with type 2 diabetes. Methods: Sixty-seven eyes of 67 patients with type 2 diabetes were enrolled. Sixty-seven age-matched non-diabetic subjects served as controls. Diabetic patients were classified by the severity of their DR: no DR (NDR), non-proliferative DR (NPDR), and proliferative DR (PDR). SAF was measured with an autofluorescence reader. Results: SAF in the diabetes patients was significantly higher than in the controls (median 2.5 (interquartile range 2.3-2.7) and 1.8 (1.6-2.3) arbitrary unit (AU), respectively, p < 0.001). There was a statistically significant increase in SAF along with the increasing severity of DR (from NDR to NPDR: p = 0.034; NPDR to PDR: p < 0.01). Logistic regression analysis revealed that SAF (OR, 17.2; p < 0.05) was an independent factor indicating the presence of PDR. Conclusions: SAF has an independent relationship with PDR in patients with type 2 diabetes. SAF measurement with an autofluorescence reader is a non-invasive way to assess the risk of DR. SAF may, therefore, be a surrogate marker candidate for the non-invasive evaluation of DR.

    ABSTRACT: Abstract Purpose: To evaluate the fibrovascular in-growth of coralline and synthetic hydroxyapatite orbital implants by reporting the enhancement patterns on Gadolinium-Dietilen triamin penta acetic acid (Gad-DTPA) enhanced magnetic resonance imaging (MRI). Methods: The medical records of 26 patients who had undergone primary or secondary orbital implantation between April 2008 and February 2011 were reviewed. T1 weighted Gad-DTPA MRI was performed between 5 and 12 months (mean 9.2 ± 5.9 months) after implantation and graded as follows to evaluate the fibrovascular in-growth of the implants; grade 1 (rim enhancement), grade 2 (peripheral foci of enhancement, not including the center), grade 3 (central, non-homogenous enhancement), grade 4 (central, homogenous enhancement) and grade 5 (central, intense enhancement).Results were analysed according to vascularization patterns on Gad-DTPA MRI. Results: Central vascularization patterns (grade 3, 4 or 5) were seen 62.5% of coralline orbital implants and 46.1% of synthetic orbital implants. Central fibrovascular in-growth of the coralline implants were found significantly more than synthetic implants (p < 0.05). Central vascularization of coralline implants with primary implantation was 75% and with secondary implantation was 50%. Synthetic orbital implantation with primary surgery demonstrated 66.6% and synthetic orbital implantation with secondary surgery demonstrated 26.6% central vascularization pattern. In both natural coralline and synthetic implants, primary orbital implantation was demonstrated significantly better fibrovascular in-growth than secondary implantation (p < 0.05). Two patients with synthetic orbital implants had dehiscence that was repaired by using autogenous fascia lata. Conclusions: In both coralline and synthetic orbital implants, central vascular in-growth was observed much more with primary orbital implantation. This study indicates that coralline HA orbital implants significantly supply more rapid and homogenous vascularization than synthetic implants.

    ABSTRACT: Abstract Purpose/Aim: Endocan is a proteoglycan specifically secreted by endothelial cells, is a marker of angiogenesis and endothelial cell activation in response to proangiogenic signals. The aim of this study was to measure the levels of endocan in the vitreous fluid from patients with proliferative diabetic retinopathy (PDR) and to correlate its levels with clinical disease activity and the levels of the angiogenic biomarkers vascular endothelial growth factor (VEGF), soluble vascular endothelial-cadherin (sVE-cadherin) and soluble endoglin (sEng). In addition, we investigated the expression of endocan and correlated it with the level of vascularization in PDR epiretinal membranes. Materials and methods: Vitreous samples from 44 PDR and 29 non-diabetic patients were studied by enzyme-linked immunosorbent assay. Epiretinal membranes from 14 patients with PDR were studied by immunohistochemistry. Results: Endocan, VEGF, sVE-cadherin and sEng levels were significantly higher in PDR patients than in non-diabetic patients (p < 0.001; p = 0.002; p < 0.001; p = 0.001, respectively). Endocan levels were significantly higher in patients with active PDR than in patients with inactive PDR and non-diabetic patients (p < 0.001). There were significant positive correlations between endocan levels and the levels of VEGF (r = 0.574, p < 0.001) and sVE-cadherin (r = 0.498, p < 0.001). In epiretinal membranes, vascular endothelial cells and myofibroblasts expressed endocan. There was a significant positive correlation between the number of blood vessels expressing CD34 and the number of blood vessels expressing endocan (r = 0.933, p < 0.001). Conclusions: Our findings suggest that upregulation of endocan expression in PDR could be a reflection of endothelial cell activation associated with angiogenesis.

    ABSTRACT: Granulocyte colony stimulating factor (GCSF) is a potent hematopoietic factor that stimulates the growth of neutrophil granulocyte precursors, and also regulates the differentiation and survival of neutrophils by inhibiting apoptosis. Incidentally, GCSF is also known to act as an endogenous ligand for brain cells, counteracting acute neuronal degeneration and contributing to long-term plasticity of progenitor cells after cerebral ischemia. Since GCSF was recently reported to be present in retinal ganglions, we examined its expression in retinal pigment epithelial (RPE) cells, which, together with retinal neurons, arise from the same underlying precursor cells.

    ABSTRACT: PURPOSE: To determine serum vascular endothelial growth factor 165 (VEGF165) levels and the association of the complement factor H gene (CFH) Y402H polymorphism in patients with exudative age-related macular degeneration (AMD) in comparison to unaffected control subjects. METHODS: Sixty-six AMD patients and 66 healthy age- and gender-matched controls were included in this case-control study. The serum VEGF165 was assayed by ELISA (R&D). Genotypes were determined by polymerase chain reaction-restriction fragment length polymorphism analysis. Chi-squared tests were used regarding the polymorphism, a t-test regarding the VEGF-levels. RESULTS: Levels of serum VEGF165 were similar in both groups (p-value = 0.2112). Genotype frequency differed significantly between patients with exudative AMD and the healthy control group (p  =  0.003136). The serum VEGF165 levels were similar irrespective of the presence of the CFH Y402H polymorphism (p  =  0.4113) and independent of the specific genotype (p  =  0.9634). CONCLUSION: In the present study, exudative AMD is not associated to serum VEGF165 levels; furthermore, our data does not establish a statistical link between VEGF165 and the CFH Y402H polymorphism.

    ABSTRACT: In a group of chickens studied after lid suture in the first month post hatching an unusually high myopia was found (n = 8 eyes; average: -21.87 Diopters). The non-operated eyes of these chicks had the same optical properties (n = 4; +0.93 Diopters) as the eyes of the normal control chicks (n = 12; +0.81 Diopters). Although enlargement of the whole eye occurred, the main determinant was an axial elongation (operated eyes, 18.0 mm; nonoperated, 13.7 mm; normal controls, 14.7 mm). The axial change involves an enlargement of the posterior as well as the anterior segments of the eye. Despite several structural characteristics specific to chicks, their eyes can serve as a model for myopia research.

    ABSTRACT: Brook trout, tile fish, and squirrel fish lenses were investigated to determine if the observed optical properties can be related to their morphology. The three distinctly different birefringent regions in teleost lenses are reflected in three lens fiber patterns of the cortex, transition zone, and the nucleus. The cortex and nucleus, which display a regular, rectangular contour with limited interdigitating associations, exhibit positive birefringence, whereas the transition zone, which displays extensive membrane interlocking projections, exhibits negative birefringence. Thus, in the transition zone, the larger membranous area dominates the balance between orientation and form birefringence. This parallels previous work in fish lenses which indicates that the transition zone is also the most labile region to temperature (freeze-thawing) and pressure variations.

    ABSTRACT: Purpose. To determine whether tranilast, N-(3,4-dimethoxycinnamoyl) anthranilic acid, influences cell proliferation and collagen synthesis by rabbit Tenon’s capsule fibroblasts (TFs) and corneal stromal fibroblasts (CFs). Methods. Rabbit TFs and CFs (7000 cells/well) were cultured in F-12 nutrient mixture supplemented with 1% FBS, plus 0, 3, 30, or 300 µM tranilast, and the number of cells was counted 72 hrs later. To determine the effect of tranilast on collagen synthesis, cells at confluence were cultured in a medium containing 0, 3, 30, or 300 µM tranilast and labeled with 3 H -proline, and the amount of radioactivity incorporated into collagenase-sensitive proteins was measured. Results. At 300 µM, tranilast decreased the number of TFs by about 27% and the number of CFs by about 45%, but had no effect on cell viability. The same concentration of tranilast reduced TFs collagen synthesis and CFs collagen synthesis. Conclusions. Tranilast may inhibit scar formation after trabeculectomy for glaucoma and after excimer laser photorefractive keratectomy.

    ABSTRACT: Experiments were designed to investigate the effects of lens calcium on the Na/K pump since elevated calcium and sodium often accompanies lens opacification. An increase in lens calcium was accomplished by culturing lenses in calcium-rich media at 21 degrees C in the absence of poisons which might directly alter sodium transport. Calcium loaded lenses were subsequently incubated at 37 degrees C in a normal culture medium to assess membrane transport function. A five-fold increase in total lens calcium to 1.45mM, resulting in a 4% increase in membrane bound calcium, had little effect on the cation pump. However, an increase in lens calcium by a factor of 100 caused a 4-fold increase in membrane bound calcium, a 50% decrease in (Na/K)-ATPase activity, and a 40% decrease in 86Rb uptake after an incubation period of 20 hrs. Details of the mechanism of enzyme inhibition remain obscure, but the data suggest the inhibition is predominantly irreversible and does not involve an interaction between calcium and ATP.

    ABSTRACT: To determine the effect of age on the extent of pathogenesis of Staphylococcus keratitis in the mouse. Corneas of young and aged mice (BALB/c, A/J, and C57BL/6) were scarified and topically inoculated with S. aureus. Slit lamp examination (SLE) and histopathology were performed, and bacterial colony forming units and myeloperoxidase activity were determined. SLE scores of infected eyes of aged mice were significantly higher at days 1 and 3 postinfection (PI) as compared to infected young mice. Histopathological changes observed in all aged mice were more severe than those in young mice. Young BALB/c and A/J mice demonstrated minimal signs of keratitis by day 3 PI, whereas aged mice of both strains demonstrated severe keratitis by day 3. Young C57BL/6 mice showed no clinical signs of keratitis, whereas aged C57BL/6 mice demonstrated moderate keratitis. Aged mice with S. aureus keratitis demonstrated increased pathology as compared to young mice.

    ABSTRACT: Purpose. We previously used mRNA differential display and identified a novel gene that is up regulated in the healing corneal epithelium. To understand the potential in vivo role of this gene, termed T4a, we cloned the full-length T4a cDNA and investigated its temporal and spatial transcription expression in healing rat corneas, as well as in developing cornea and skin. Methods. The displayed T4a cDNA was used to identify clones from a rat cDNA library derived from healing corneal epithelia. The cDNA clones were sequenced and the sequence was analyzed with the Blast program. In situ hybridization was performed using digoxigenin-labeled riboprobes and cryostat sections from healing and developing cornea as well as skin. Results. The T4a cDNA had 2538 bp with an open reading frame of 2178 bp, consistent with a conceptual translation product of 725 amino acid residues, a calculated molecular mass of 83.1 kD and theoretical pI of 6.93. Although T4a exhibited no sequence homology with known genes in the GenBank, it matched a large number of Expressed Sequence Tags (ESTs) from human, mouse and rat tissue cDNA libraries; more than half of the murine T4a ESTs were from embryonic DNA libraries. Sequence analysis revealed numerous phosphorylation and myristoylation sites in the deduced amino acid sequence of T4a. In the wounded rat cornea, intensive T4a mRNA staining was observed in the epithelium at all stages of re-epithelialization indicating that the expression of T4a is wound-related. In 7 day old mice, an abundant level of T4a transcripts was found in the epidermis and hair follicles, as well as in the corneal epithelial layer. High levels of T4a mRNA staining persisted in the developing postnatal corneal epithelia. In contrast, weak mRNA staining was only detected in the basal layer of the adult epidermis and corneal epithelium. Conclusion. These results indicate that T4a expression correlates with re-epithelialization of the cornea and maturation of the cornea and skin, suggesting a role for this gene in epithelial development, differentiation, and wound healing.

    ABSTRACT: The major objectives were to investigate functional expression of nucleoside transporters on the rabbit cornea and to delineate mechanism of corneal permeation of acyclovir (ACV) and idoxuridine (IDU). Methods. Transport studies were conducted with isolated rabbit corneas at 34 degrees C using [(3)H]thymidine, [(3)H]ACV and [(3)H]IDU. Thymidine transport across rabbit cornea comprised of saturable (K(m) = 14.9 +/- 9.7 microM and V(max) = 0.045 +/- 0.0087 nmol/min) and non saturable (k(d) = 0.00015 +/- 0.000013 microl/min) components. Both purine and pyrimidine nucleosides including inosine inhibited transport of [(3)H]thymidine. However, nucleobases adenine and thymine did not have any inhibitory effect on thymidine transport which was sodium dependent with a Na(+): thymidine coupling ratio of greater than 1 : 1 indicating that the nucleoside transporter is of the N3 type. Although IDU inhibited transport of [(3)H]thymidine, unlabeled IDU and thymidine did not inhibit [(3)H]IDU transport suggesting that IDU was binding to the transporter but was not translocated by it. ACV did not affect transport of [(3)H]thymidine. Moreover, thymidine, adenine or unlabeled ACV did not inhibit [(3)H]ACV transport. Permeability coefficients of ACV and IDU over a 4 fold concentration range did not show any significant difference confirming that these antiviral agents permeate the cornea by passive diffusional mechanism. Functional expression of a N3 type sodium dependent nucleoside transporter has been demonstrated on the rabbit cornea. Antiviral nucleoside analogs ACV and IDU are not substrates for this transporter and appear to permeate the cornea by simple passive diffusion.

    ABSTRACT: The interaction between several adrenergic agonists (epinephrine, norepinephrine and isoproterenol) and relatively specific beta 1- and beta 2-antagonists has been examined on fluid permeability of the isolated rabbit ciliary epithelium. A specific beta 1-antagonist (metoprolol) had little effect on the permeability increase induced by the agonists, whereas butoxamine (a specific beta 2-antagonist) caused an inhibition of the normal agonist-induced permeability increase. The data suggest that these three adrenergic agonists primarily affect the beta 2-receptor in the ciliary epithelium in order to induce their effects on fluid permeability.

    ABSTRACT: The axial dimensions of eyes of macaque monkeys which had experienced long term monocular or binocular eyelid closure were measured using ultrasonography. The axial length of the vitreous chamber and total eye were significantly increased in the sutured eye of 3 monkeys and significantly decreased in the sutured eye of 2 monkeys among the 6 monocularly lid sutured subjects. Binocular eyelid suturing induced large interocular differences in these ocular dimensions. We conclude eyelid suture interrupts the regulation of posterior segment growth. This usually results in axial elongation but may also produce axial shortening.
