Objective To evaluate the cytokine profile in tear and aqueous humor in primary open-angle glaucoma before trabeculectomy and correlate preoperative cytokine levels with the surgical outcome. Methods Prospective study. Twenty-nine patients with primary open-angle glaucoma undergoing primary trabeculectomy were included. Levels of 27 cytokines were measured in tear an aqueous humor using the Bio-Plex Pro Human Cytokine 27-Plex Immunoassay kit (Bio-Rad Laboratories, Hercules, CA, USA). Results 29 patients who underwent trabeculectomy were included and their first-year follow-up visits were recorded. Mean age was 76.0 ± 7.0 years (range 56–84), mean intraocular pressure was 18.2 ± 3.6 mmHg and mean number of topical medications was 2.3 ± 0.9. At the one-year visit, 5 patients were classified as surgical failure. In aqueous humor, preoperative cytokine levels of regulated on activation normal T cell expressed and secreted (RANTES) were significantly higher in those patients with surgical failure at one year. IL-8 in tear and interferon gamma-induced protein (IP-10) in aqueous humor correlated positively with one-year IOP reduction. No statistically significant correlations were found with changes in visual field mean defect or global peripapillary retinal nerve fiber layer thickness (all, p >0.05). Conclusions Preoperative RANTES levels in aqueous humor as well as other cytokines could serve as useful biomarkers for trabeculectomy outcome.

Summary Background Glaucoma is a highly prevalent eye disease related to optic nerve lesions and visual field defects. Primary Open-Angle Glaucoma (POAG) is a type of glaucoma that occurs frequently with unknown etiology. In this study, we investigated the serum levels of selenium, selenoprotein P1, glutathione, hemolysate glutathione peroxidase1 (GPx1) activity and aqueous humour selenium in POAG patients. Methods Ninety sex- and age-matched subjects (POAG patients; n=45 and, controls; n=45) with the controlled confounders (smoking, hypertension and alcohol beverages) were recruited on clinical histories and exams. The serum and aqueous humour selenium levels were measured using GFAAS technique. The serum selenoprotein P1 level was assayed with the ELISA method. The hemolysate GPx1 activity and serum reduced glutathione level were also measured using known colorimetric techniques. Results The serum selenium (P=0.01) and selenoprotein P1 (P<0.001) levels were significantly high in POAG patients. Furthermore, the aqueous humour selenium level was significantly high among patients as compared to controls (64.68±13.07 vs. 58.36±13.76 ng/mL, P=0.02). The results did not show a significant difference (P=0.36) in the hemolysate GPx1 activity between the groups. The cutoff points for intraocular pressure (IOP) and serum selenoprotein P1 parameters were estimated to be 39 mmHg (sensitivity 97.5%; 1-specificity 6.5%) and 188 mg/mL (sensitivity 93.5%; 1-specificity 14%), respectively.

The purpose of this study was to investigate the aqueous humour of glaucomatous and non-glaucomatous patients by freeze-controlled crystallisation qualitatively to detect a possible difference. Aqueous humour was taken from 20 patients with different kinds of glaucoma (11 primary open-angle glaucoma, eight pseudo-exfoliation glaucoma, one pigmentary glaucoma) and compared with samples from 40 patients with cataracts and to samples from seven patients with cataract and glaucoma; 1μl of each sample was applied to a microscope slide and put in a deep-freezer at a constant temperature of -20°C for 24 hours. During this time, the water evaporated and distinct crystal patterns developed. These patterns were examined stereo-microscopically, stored digitally and compared with each other. Many distinct crystals of different sizes and formations were obtained. No obvious differences in the crystal patterns could be found between the three groups (patients with glaucoma, cataract or cataract and glaucoma). As a multifactorial disease, open-angle glaucoma is characterised by specific changes to the trabecular meshwork cells with an accumulation of deposits of extracellular matrix. Since the trabeculum is rinsed consistently by aqueous humour, changes of the compounds might influence these cells. Alterations concerning this were published. In contrast to the ferning test, one of several methods of examining fluids with patterns that are highly dependent on temperature and humidity, our examinations with freeze-controlled crystallisation at a constant and controlled temperature of – 20°C gave more valid results. In our study we could not find obvious differences in the crystal patterns of patients with cataract, glaucoma or cataract and glaucoma.
