“…The study group was recruited among patients who were admitted because of POAG to the Department of Ophthalmology and Visual Rehabilitation, University Hospital WAM, Central Veteran Hospital in Lodz, Medical University of Lodz, Poland. The criteria for inclusion of subjects in the study group with primary open-angle glaucoma (POAG) was diagnosis of POAG by an ophthalmologist in accordance with the applicable criteria for diagnosing the disease (documented raised intraocular pressure, documented changes in the optic disc correlating with changes in visual eld) [14,15].…”

Objective The aim of the study is to assess the nutrition of patients with glaucoma and the relationship between the adopted nutrition models, the degree of overweight and obesity, and primary open angle glaucoma. Background Glaucoma is a serious eye disease, which, without proper treatment, can lead to total blindness. It affects 70 mln people in the world, and has been defined by WHO (World Health Organization) as significant burden for the 21st century society. Elevated intraocular pressure is the most important factor of occurrence and progression of the disease. Suboptimal health-related behaviors, including inadequate diet of glaucoma patients are suggested as additionalfactors contributing to development of the disease. Material and methods 625 adults aged 45 years or older were enrolled in the study. The study group comprised 312 subjects diagnosed with Primary Open-Angle Glaucoma [POAG], including 238 women [W]- 76% equal to 476 eyes and 74 men [M]- 24% which is 148 eyes. Control group consisted of 313 subjects with no glaucoma diagnosis – including 202 women [W - 64%, 404 eyes] and 111 men [M - 36%, 222 eyes]. General data, including anthropometric indices and Body Mass Index [BMI] [kg/m2], was collected during the interview with the patient including original questionnaire. The daily nutrition of the study subjects was analysed based on the Questionnaire obtained from the Computer Program - Diet 2.0 developed at the National Food and Nutrition Institute in Warsaw. Nutritional value and composition of consumed meals were also assessed. Results The analysis of the obtained data showed changes regarding obesity and diet-related factors between POAG and control group. Below are mentioned most interesting results. Obesity [BMI>30] was found to be significantly more prevalent among subjects with POAG, regardless of gender [p<0,00000]. The distribution of the number of meals consumed per day was statistically significantly different between the POAG and control group [p=0.001321]. The meals of men with glaucoma were found to be richer in saturated [p=0,001] and unsaturated fats [p=0,023] as well as cholesterol [p=0,039] compared to the dishes consumed by men in the control group. Analysis of the components of meals consumed by women in POAG group showed significant differences compared to women in the control group as to both their number and "size" (grammage) of ingredients [p<0,02]. The results showed that women with POAG ate statistically more frequently 3 meals per day, consuming higher amount of ingredients such as cholesterol and animal and vegetable proteins. Total daily energy values consumed by the subjects with glaucoma were higher than in the control group, although statistically significant values were observed only among women with glaucoma [p<0,0001]. The level of energy obtained from fat consumption was higher among both men [p=0,016] and women with glaucoma [p=0,04] than in the control group. The percentage of energy obtained from alcohol consumption was higher among subjects with glaucoma, with statistically significant differences observed only among women [p=0,0044]. Conclusion POAG correlated with inadequate nutrition model and overweight as well as obesity of subjects. The population of patients with glaucoma, unlike the general healthy adult population, was characterized by higher values of: body weight, BMI and total daily energy obtained from meals, as well as different daily meal components, fewer meals consumed, greater energy supply derived from fat compared to protein, lower water intake and larger alcohol ingestion in the female population. Concluding from the results of this research, it is recommended to intensify the education of POAG patients in terms of proper nutrition. Such action may have beneficial impact on prevention, occurrence and modification of the course of POAG. Apparently, further research is needed to determine the role of efficacy and safety of diet modification and nutritional supplementation in the treatment of glaucoma.

“…Standard automated perimetry (SAP) and frequency doubling perimetry (FDP) are two alternate technologies available to quantify the extent and degree of visual field loss due to glaucoma. 1 The Humphrey visual field analyzer (HVF) with SAP (750 I series; Carl Zeiss Meditec, Dublin, CA, USA) estimates differential light sensitivity using white targets and is considered as the gold standard in evaluating the visual field. 1,2 The frequency doubling perimetry (FDP) (Welch Allyn, Skaneateles Falls, NY, USA, and Carl Zeiss Meditec, Dublin, CA, USA) utilizes low-spatial-frequency sinusoidal grating target.…”

SITA standard testing with Humphrey visual field analyzer versus full threshold testing with frequency doubling perimetry: a comparison of patient preference and perception

Purpose: To compare patient preference for Swedish Interactive Threshold Algorithm (SITA) standard 24-2 protocol in Humphrey visual field analyzer (HVF) and full threshold N-30 protocol in frequency doubling perimetry (FDP) by primarily evaluating their perception about the test procedure and test targets along with surveying the factors that influence the patient concentration during perimetry and elements that determine the level of perimetry task difficulty. Methods: This study enrolled a subset of subjects from the Chennai Glaucoma Study. Each subject underwent a comprehensive ophthalmic examination after which they were randomly allocated to perform HVF and FDP with a 30-minute interval between the two procedures. SITA standard 24-2 protocol in HVF and full threshold N-30 protocol in FDP were used. This was followed by the administration of a questionnaire that mainly assessed the components such as (a) the patient preference for test procedure and test targets, (b) the factors influencing the patient concentration during perimetry performance, and (c) the impression about the level of perimetry task difficulty. The patient responses from the survey for each of the subcategories were obtained and analyzed using Chi-square test. Results: A total of 42 subjects with a mean age of 59.7 (SD 9.7) years were included, among which 18 (42.86%) were male and 24 (57.14%) were female. Thirty-two (76.19%) subjects felt both FDP and HVF were easy to perform, eight subjects (19.05%) felt that both perimetry techniques were difficult to perform, and two subjects (4.76%) found FDP procedure was easier than HVF, whereas the distribution was not statistically significant (Chi-square, p = 0.7). Pressing the button as a response to peripheral stimulus perception and inability to maintain steady central fixation for prolonged duration were the most commonly reported factors that influenced the level of difficulty of the perimetry tasks. A dark room ambience set for performing HVF was preferred by 32 (76.20%) subjects. Conclusion: There was no significant difference in the patient preference for test procedure and peripheral test targets. A black central fixation as in FDP and dark room ambience set for HVF were preferred.

“…Increased intraocular pressure is the main risk factor in the occurrence of glaucoma, but the existence or absence of an increased intraocular pressure does not define this disease. Glaucoma is characterized by the progressive destruction of optic nerve fibers, which is responsible for the transmission of visual information from the eye to the brain [1].…”

Our study aimed to determine pain levels and the state of welfare connected to laser-based procedures in the treatment of patients diagnosed with uncontrolled glaucoma. The study group included 100 eyes of 100 patients diagnosed with glucoma, 50 of them being treated with micropulse transscleral laser cyclophotocoagulation, and the other 50 eyes being treated with continuous transscleral laser cyclophotocoagulation. We used visual analog scale to gather information from each patient. After analysing the individual information the following results were obtained: the pain level for the micropulse transscleral laser cyclophotocoagulation was 60.23 mm, signifying moderate pain; and the pain score for the continuous transscleral laser cyclophotocoagulation was 76.34 mm, corresponding to moderate-intense pain. Pain level generated by minimally invasive laser procedures is discussed.
