Rheumatoid arthritis is a chronic multisistemic disease of an unknown cause characterised by persistens inflammatory synovitis which results in destruction cartilage and bone erosions. RA is a systemic disease with various out of joint manifestations of different clinical importance, among which rheumatoid knots, rheumatoid vasculitis, pleuropulmonal and ophthalmological manifestations are the most prominent ones. The most frequent changes of the eye in patients with RA are keratoconjunctivitis sicca (KCS), episcleritis and scleritis and ulcerous keratitis. Out of 70 examined patients, 52 (74.3%) are female, and 18 (25.7%) of male sex (ratio 4:1), average age 56.47. In 18 (25.71%) RA diseased patients eye changes found are as folows: secondary Sjögren syndrom, that is keratoconjunctvitis sicca in 18.57%, only in female patients, episcleritis nodosa and scleritis in 4.29%; 2.86% in male and 1.43% female patients and ulcerous keratitis in 2.86% RA diseased patients. 

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.

Ankylosing spondylitis is a chronic rheumatoid inflammation with characteristic synovitis of sacroiliac joints and vertebrae of spinal column and fewer coxofemoral and glenohumeral and periferal joints. The disease is of an unknown etiology and shows strong correlation with histocompatibile antigene HLA-B27 wich is found in 90% AS diseased patients. Acute anterior uveitis is the most frequent extra-articular manifestation, it can precede spondylitis and is found in at least 20% AS diseased patients. Acute anterior uveitis is mostly bilateral, with recidives and in inadequate treatments results in complicate cataract and secondary glaucoma. Out of 41 patients with ankylosing spondylitis 36 (87.8%) is of male , and 5 (12.1%) female sex (ratio 9:1). The youngest patient was 25 and the oldest 69 years of age, average age of the diseased was 38.45. Acute anterior uvetis is found in 11, that is 26.8% diseased patients. The length of uveitis is approximately 28+/- 10 days. In 7 patients (63.64%) AAU is found in both eyes. Out of 11 patients with with AAU, 3 patients (27.27%) had more than first attack,7 (63.64%) had 1-5 recidives, and only 1 patient had more than 5 recidives. The most frequent type of exudation is serofibrose (77.78%), then follows fibropurulent-hypopyon (16.67%) and serose (5.55%). Out of 18 eyes, in 14 (77.78%) back synechies were formed. However, these synechies are in most cases broken by the use adequate therapy.

Seronegative arthropathy represents group of rheumatic diseases which affects younger patients, more often male. Ocular findings are numerous such as conjunctivitis, iridocyclitis, and they are a part of extraarticular clinical manifestations. Acute anterior uveitis, as most common ocular manifestation, could be a sole or associated morbidity condition at the forme of systemic diseases.

Exudative age-related macular degeneration is leading cause of irreversible vision loss in developed countries. Subfoveal localisation of choroidal neovascular membrane is the most difficult form for treatment. At the last three years, the new group of agens well-known as anti-VEGF agens was approved for treatment of exudative AMD. In that purpose, intravitreally administrated agens is recommended. Efficacy and safety of anti-VEGF agens were proved in short-time follow up period.

Diabetic retinopathy, particularly diabetic maculopathy, are leading cause of visual loss in the world.Purpose: to estimate type of diabetic maculopathy in patients with diabetic retinopathy. Method: hospital based study. 118 patients with diabetic retinopathy underwent complete ophthalmologic examination ( mean age 58,1 years, male 78, female 40; 7% were diabetes type 1 patients; 46% had nonproliferative diabetic retinopathy (NPDR) and 54% had proliferative diabetic retinopathy (PDR). Results: 88 patients (74% of all) had diabetic maculopathy. The most common type of diabetic maculopathy was diffuse (60% of all patients ), afterward focal (33% patients) ischemic maculopathy (both with PDR) had two patients (3%) and five patients had mixtus (7%) . Conclusions: diffuse diabetic maculopathy is the most common type of maculopathy both in NPDR and PDR

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
