- A cross-sectional population-based study of 1636 subjects over 40 years of age from the South Region of Brazil showed that the awareness of glaucoma disease was considerably lower (3.4%) than that of Systemic Arterial Hypertension (SAH) (58.7%) and of diabetes (10.9%). Six (10.7%) glaucoma cases were already aware of their diagnosis, while 700 (72.9%) SAH cases and 161 (90.4%) diabetes cases were already aware of their diseases (p<.001, chi-square test). The low rate of previous glaucoma diagnosis represents a public health problem that must be tackled in order to reduce the burden of glaucoma blindness in developing countries. (Lisandro M.

- In a randomised, controlled clinical trial, glatiramer acetate was studied in patients with severe nonproliferative or early proliferative diabetic retinopathy. Thirteen patients (23 eyes) were included in the study group and thirteen patients (24 eyes) were included in the control group. OCT showed a statistically significant difference in retinal nerve fibre layer (RNFL) thickness in the inferior peripapillary region and, in the control group, average thickness with thinner measurements at one-year post-PRP. Glatiramer acetate may have a neuroprotective effect on the RNFL following photocoagulation for diabetic retinopathy. (Augusto Paranhos Jr, Sao Paulo, Brazil)
- In a prospective analysis, 88 eyes of 88 OH or OAG patients were submitted to modified Diurnal Tension Curve (mDTC). IOP was measured at 8:00 am, 11:00 am, 14:00 pm and 16:00 pm. It was followed by the Water Drinking Test (WDT). IOP peaks detected by the WDT, diurnal fluctuation and IOP measurements during each time point of the mDTC presented excellent reproducibility.

- Chronic treatment with melatonin in an experimental model of glaucoma in rats prevented functional alterations and decreased the vulnerability of retinal ganglion cells to the deleterious effects of ocular hypertension, probably by antagonizing the effect of ocular hypertension on glutamatergic and nitridergic systems and on oxidative damage. (Florencia Lanzani, Buenos Aires, Argentina)
- In a cross-sectional study, patients with obstructive sleep apnea syndrome (OSAS) were compared with controls (patients with audition deficiencies). The prevalence of glaucoma was not statistically significant in relation to the control group. The most prevalent glaucoma diagnosis in the OSAS group was normal pressure glaucoma.
