Introduction. According to the level of intraocular pressure (IOP), open angle glaucoma is divided into high tension glaucoma (HTG) and normal tension glaucoma (NTG). Objective. To determine if there are differences in the distribution of patients by age and sex between NTG and HTG. Methods. Our prospective study included 30 patients with NTG and 30 with HTG. A complete eye examination was performed. The examination included measuring of intraocular pressure by Goldmann applanation tonometry, examination of optic disc head by indirect ophthalmoscopy with Volk 90 D lens and visual field examination using the Octopus program. Results. The average damage of visual field in the group of patients with NTG was 8.14?4.43 dB, while in the group with HTG it was 7.40?2.84 dB (p>0.05). The average age of the group of patients with NTG was 66?11.58 years, while among those with HTG the average age was 59.7?11.63 years (p<0.01). Among the patients with NTG there were three times more women than men (?2=9.124; p<0.01), while in the group of patients with HTG there were more men than women, but without statistically significant difference between the tested groups (?2=1.851; p>0.05). Conclusion. Open angle glaucoma is a disease of elderly population. According to our results, risk factors for this disease can be age and sex. NTG is more frequently present than HTG among elderly population and females.

The Impact

Purpose. To compare the impact of visual field (VF) testing on intraocular pressure (IOP) change trends between healthy subjects and glaucoma patients. Methods. We recruited healthy volunteer subjects who did not have previous ocular diseases and open-angle glaucoma patients who were medically controlled well. IOP in both eyes of each participant was measured by using a noncontact tonometer at five time points: before, immediately after (0 minute), and 10, 30, and 60 minutes after the standard automated perimetry. Repeated measures ANOVA was used to analyze the effect of VF testing on IOP change trends in healthy and glaucoma eyes. Results. Forty healthy subjects (80 eyes) and 31 open-angle glaucoma patients (62 eyes) were included for the study. The baseline IOP of healthy and glaucoma eyes was 16.11 ± 3.01 mmHg and 15.78 ± 3.57 mmHg, respectively. After the VF testing, the IOP in healthy eyes was decreased by 1.5% at 0 minute, 6.5% at 10 minutes (P<0.001), 6.6% at 30 minutes (P<0.001), and 7.0% at 1 hour (P<0.001), indicating that this reduction was sustained for at least 1 hour. However, the IOP in glaucoma eyes was increased by 12.7% at 0 minute (P<0.001) and, then, returned towards initial values 1 hour after the VF testing. Conclusions. IOP change trends after VF field testing between healthy subjects and glaucoma patients were quite different. VF testing led to a mild and relatively sustained IOP decrease in healthy subjects, whereas IOP in open-angle glaucoma patients tended to significantly increase immediately after VF testing and, then, returned to pretest values after 1 hour. These findings indicate that the factors of VF testing should be considered in the clinical IOP measurements.

Glaucoma Treatment

The United Kingdom Glaucoma Treatment Study (UKGTS) was a randomized, triple-masked, placebo-controlled trial comparing topical latanoprost, a prostaglandin analogue, with placebo in patients with newly diagnosed, previously untreated open-angle glaucoma (OAG). Compared to placebo, the latanoprost group showed a large, statistically significant reduction in the rate of glaucomatous visual field deterioration by 24 months. The UKGTS was the first placebo-controlled trial to show visual field preservation through lowering of intraocular pressure with topical drugs in patients with OAG, and the first to show the visual field–preserving effect of a topical prostaglandin analogue.

Glaucoma Treatment

The Collaborative Initial Glaucoma Treatment Study (CIGTS) was a randomized clinical trial to determine whether patients with newly diagnosed open-angle glaucoma (OAG) were managed better by initial treatment with medications (using a stepped regimen of medications starting initially with a topical beta-blocker) or by immediate filtration surgery (trabeculectomy with or without 5-fluorouracil). Although the surgery group achieved a lower mean intraocular pressure (IOP) than the medication group, both groups had similarly low rates of visual field progression. Three measures of IOP fluctuation over extended time, the range of IOP, the standard deviation of IOP, and the maximum IOP, seem to play an important role in visual field progression The results showed that more aggressive treatment was warranted when undue elevation or variation in IOP measures is observed.
