Ocular contusion followed by hyphema is very common ophthalmologic problem. Aim: to determinate basic epidemiologic characteristics, comorbidity of other ocular findings, as well as complications associated with different grade of hyphema. Method: 55 patients with hyphema and ocular contusion were examinated. Results. Male had hyphema almost four times more often then women (80%:20&); workers (34.5%), afterward pensioners (20%) and pupils (18.2%) were the most often injured. The most frequent causes were the wood (43.6%), stone (10.9%) and vegetable foreign body (9.1%), The first grade of hyphema was demonstrated at 30 patients (54.5%), the second at 16 (29.1%), the third at 6 (10.9%) and the fourth at 3 (5.5%). The most frequent associated ocular findings regarding to segments were the following : haematoma palpebrarum, subconjunctival hemorrhage, erosio corneae and haemophthalmus. Secondary glaucoma was the most common ocular complication and it was finding at one patient with the first stage of hyphema but at all patients with the fourth grade of hyphema. Conclusion: grade of hyphema is directly proportional with a grade of ocular complications and frequency of associated ocular findings.

Chemical injuries of the eye i.e. causoma means 4% up to 10% of all ocular trauma cases. Purpose: to determinate basic socio-epidemiologic characteristics of patients who has been hospitalized due to causoma. Method: prospective case control study carried on 54 patients who havå been treated at Department of Ophthalmology Health Center K.Mitrovica and Clinic of Eye Disease in Nis. Results: in total, 40 male and 14 women were injured (mean age 41.8 years). The bricklayers, painters and construction-workers are the most frequent injured. Injuries caused by alkalis were significant prevailing in relation to those caused by acids (64.8% vs. 35.2). Monocular causoma were almost twice more frequent. Accident as a manner of injury was in 96.3% of all cases. Men were injured by caustic lime and sulphuric acid while women were injured by sodium hydroxide, hydrochloric acid and acetate acid. More serious clinical appearance had a patients with injuries caused by explosion of accumulator because of associated mechanical injuries of the eye.

Any kind of ocular lens opacification is well known as cataract. Most cataracts are age-related, so called senile cataract. Cataractogenesis as process involves either pathological and natural aging processes. Chronical oxidative stress is considered as primary factor in age-related cataractogenesis. In this study we measured concentration of lipid hydroperoxides, sulfhydril groups (SH) and entire antioxidative capacity,as well as ocular superoxide dismutase and catalase activity in 11 subjects with diabetes mellitus (DM) type 2 and cataract and in 39 nondiabetic subjects with senile cataract. All patients underwent complete ophthalmological examination before they were surgically treated by phacoemulsifications. 0 During the intervention, aqueous sample in volume 0,2 was aspirated and refrigerated in -20 C and preparated for further biochemical analysis. Parameters of antioxidative power in diabetic subjects with cataract have decreased values (sulfhydril groups and antioxidative potential - FRAP test) in aqueous while one of lipid peroxidation product has increased value (lipid hyperoxide). Aqueous catalase activity in subjects with diabetes and senile cataract is remarkably higher compared with nondiabetic subjects (p<0.0.5). Oxydative stress and antioxidative capacity are well known risk factor in cataractogenesis but in DM 2 patients, oxydative stress is more intensive than in control group.

Visual acuity in the patients who suffered from end stage renal disease (ESRD) on hemodialysis (HD) treatment is essential prerequisite of good life quality. PURPOSE: to evaluate the prevalence and causes of visual impairment at the patients on HD. METHOD: 71 patients on HD were assessed with this study. The main outcomes were best corrected visual acuity and primary cause of visual impairment. RESULTS: statistical significance obtained for the followed refraction errors: 42 % of patients had hyperopia (p<0.000; 95% CI 0.36-0.48) and 15% of them myopia (p=0.030; 95% CI 0.11-0.19) as well as low vision (amblyopia) at 6% (p=0.024; 95%CI 0.03-0.09). CONCLUSION: it's necessarily to provide regular monitoring of all patients on HD. Prevalence of refractive errors and visual impairment is more often among patients on HD then on general population
