Background/Aim. Primary open-angle glaucoma is a multifactorial and progressive neuropathy, characterised by the acquired loss of ganglion cells of the retina and their axons. One of the risk factors for primary open-angle glaucoma is myopia over 5 diopters (D). The aim of our work was to investigate two groups of patients with primary open-angle glaucoma and myopia by using confocal scanning laser ophthalmoscopy, and to find out if the size of refractive error influences optic disk morfometric characteristics. Methods. One hundred eyes of one hundred patients with primary open-angle glaucoma and myopia were involved in our study. All the patients were classified into two groups, the first one with myopia < 5 D, and the second one with myopia ≥ 5 D. The Heidelberg retina tomograph is a technique we used in our study. We analized morfometric parameters of patients optic discs, with the aim to find a correlation between the parameters in each group separeatly, and also to find differences between the same parameters from both groups. Results. There were significant differences in disc area, cup area, rim area and mean RNFL thickness between the two groups. The size of damage of neuroretinal rim in the group with high myopia was 27%, and in the group with lower myopia 14%. The most frequently damaged segment of neuroretinal rim in the patients with high myopia was nasal segment and in the patients with low myopia infero-temporal one. The least frequently damaged segment of neuroretinal rim in both groups was temporal one. Conclusion. Optic discs of glaucomatous patients with high myopia have bigger diameter, also bigger and more irregularly distributed damaged zone of neuroretinal rim, and also thinner retinal nerve fiber layer compared to glaucomatous patients with lower myopia.

Introduction. Congenital uveal ectropion (CEU) is a rare, non-progressive condition often accompanied with eyelid ptosis, anterior insertion of the iris, disgenesis of the iridocorneal angle and glaucoma. Case report. We present a case of a seven-year-old girl with a congential unilateral uveal ectropion and a secondary glaucoma which had daily variations from 13 up to 50 mm Hg. The patient had no other abnormalities of the iris or underlying systemic diseases. Introduced local anti-glaucomatous therapy initially normalized intraocular pressure (IOP), but failed to provide long term normalisation. Trabeculectomy normalized the IOP which resulted in the reduction of the cup/disc ratio and restitution of neuroretinal rim. The rim area increased to 1.716 mm2 (0.958 mm2 preoperative) rim volume, was 0.666 mm3 (0.195 mm3 preoperative) while cupdisc (C/D) ratio decreased to 0.330 (0.626 preoperative) as well as linear C/D=0.574 (0.791 preoperative). Neuroretinal rim (NR) was preoperatively preserved in the Ti segment, damaged in T, Ts, N, Ns segments, and borderline in the Ni segment. Postoperatively, neuroretinal rim was preserved in all segments. Conclusion. In the presented case trabeculectomy induced recovery of the nerve tissue of the optic nerve head which was confirmed by Haidelberg Retina Tomograph II (HRT II). The treatment results have been maintained during the follow-up period of nine years without topical or systemic antiglaucomatous therapy. Although CEU is a non-progressive and benign eye disease, associated glaucoma can cause severe optic nerve damage if not detected early and treated properly. As can be seen in the presented case, an adequate treatment can prevent and even reverse optic disc neuropathy. © 2018, Inst. Sci. inf., Univ. Defence in Belgrade. All rights reserved.

Outline of Cases This is a case series of five patients with CHC and RD who were successfully operated using one of two different surgical techniques: pars plana vitrectomy (PPV) + silicone oil internal tamponade and/or scleral buckle with encircling band with laser photocoagulation (SB+EB+LPC) around the coloboma. The purpose of this paper is to present how to successfully handle patients with CHC, who have concurrent retinal detachment in the same eye and to compare two different techniques and indications for the predominant use of one of them in a specific case.; Conclusion Both surgical techniques can be applied with equal success in the operation of retinal detachment in eyes with the chorioidal coloboma. Which one will be used depends only of the posterior segment of eye findings. We use scleral buckling in cases with RD accompanied by CHC when the peripheral break is evident and there are no breaks in the coloboma itself. We also perform, 2-3 days after surgery, laser burns around the coloboma, which is our modification of this technique. In all other cases it is indicated to perform PPV+silicon oil internal tamponade.; Introduction Choroidal coloboma is a congenital defect caused by an inadequate closure of embryonic fissure. About 40% of the eyes with the choroidal coloboma (CHC) develop the retinal detachment (RD). It is extremely difficult to manage these cases due to the lack of pigmentation at the site of choroidal coloboma. © 2014, Serbia Medical Society. All rights reserved.

Introduction/Objective Iridocorneal endothelial (ICE) syndrome incudes 3 clinical forms: progressive iris atrophy, Chandler’s syndrome, and Cogan–Reese syndrome. It is characterized by various degrees of iris atrophy, corneal endothelial changes, uveal ectropion, corectopia, peripheral anterior synechiae (PAS) and secondary glaucoma. The aim of the study was to illustrate forms of ICE syndrome, determine frequency of secondary glaucoma with emphasis on cases with uveal ectropion, analyze response to medicament treatment and the need for surgical treatment in intraocular pressure (IOP) control. Methods Patients underwent slit lamp examination, applanation tonometry, gonioscopy, ophthalmoscopy, Humphrey visual field testing and Heidelberg retina tomography. Patients were divided into two groups: group I, without uveal ectropion (22 patients) and group II, with uveal ectropion (14 patients). Results A total of 36 patients were examined in a 10-year period. The average age was 38 years, male to female ratio 1:2. Secondary glaucoma was confirmed in 26 (72.2%) patients, out of which 12 (54.5%) in group I and 14 (100%) in group II. PAS were more frequent in group II. In group I, mean initial IOP was 37 mmHg, and after medicament treatment 26 mmHg. Secondary glaucoma was controlled in 50% and remaining 50% underwent surgical treatment. In group II, mean initial IOP was 49 mmHg, and after medicament treatment 32 mmHg. All 14 patients (100%) underwent surgical treatment in order to achieve IOP control. Conclusion ICE syndrome is a rare, progressive disease, with high incidence of secondary glaucoma, which is more frequent in cases with uveal ectropion. In these cases, medicament treatment is not effective and trabeculectomy with antimetabolite application is necessary. © 2017, Serbia Medical Society. All rights reserved.

The analysis of ten unusual eye injuries, and the discussion of appropriate preventive measures. Ten patients hospitalized at the Clinic of Eye Diseases, Clinical Center of Serbia, Belgrade, in the period from January 2000. to December 2009. were presented. Following data were taken in account: sex and age of the patient, injured eye, the mechanism of injury, type of the injury, applied treatment and final visual acuity. The circumstances of the eye injuring of ten patients were described. The eye injuries in all cases occurred in a bizarre way and they were severe enough to require hospital admission. The surgery was necessary in seven patients. Three injured eyes resulted in blindness, and two additional had subnormal vision. In three quarters of discussed cases injuries can be avoided. It is necessary to implement protective measures constantly and consistently and to think about the possible consequences of certain activities. Particular attention should be paid on safety of children. The iatrogenic injuries require special consideration.
