Aim. To find out the influence of learning effect on various reliability parameters and global indices of standard automated perimetry in cases of primary open angle glaucoma. Method. Thirty eyes of 30 patients of Primary Open Angle Glaucoma constituted material for this prospective observational study. All the patients underwent standard automated perimetry three times on three different days within one week on G program of Octopus Visual Field Analyzer. The details of reliability indices, global indices, and test duration were compiled and analyzed. Result. A male preponderance was observed with a mean age of 53.43 years. The mean false positive was found to be 11.13, 6.07, and 2.40 on visit 1, visit 2, and visit 3, respectively. The mean false negative was found to be 13.73, 9.33, and 6.30 on visit 1, visit 2, and visit 3, respectively. The mean fixation loss was found to be 7.53, 3.83, and 1.60 on visit 1, visit 2, and visit 3, respectively. The mean deviation was found to be -10.14, -5.75, and -3.11 on visit 1, visit 2, and visit 3, respectively. The pattern standard deviation was found to be 5.58, 4.63, and 4.35 on visit 1, visit 2, and visit 3, respectively. The mean test duration was found to be 7.68, 6.21, & 5.51 minutes for visit 1, visit 2 and visit 3, respectively. All the values were statistically highly significant except for the pattern standard deviation. Conclusion. At least three standard automated perimetry tests should be performed for all glaucoma patients in order to obtain a base line perimetry chart.

The authors are discussing over 80 articles that they have published in the last 5 years in the renowned ophthalmic journals worldwide, which have approached, for the first time in the ophthalmic literature, the following 4 topics: the acute central/ hemicentral retinal vein occlusion, the therapeutic interventions in the fellow eye of patients with unilateral malignant glaucoma, the persistent diabetic macular edema, and the current researches in patients with neovascular age-related macular degeneration.

Competition in health care services has been considered as a core component in the consumer value mechanism. In Romania, the emergence of private ophthalmology services has as outcome a positive-sum competition which focuses on prevention, diagnosis and treatment of eye related diseases and disorders and improved value. The purpose of this paper was to provide an insight into the knowledge used by consumers when they make a decision regarding a private ophthalmology service with a specific interest on competition. A research model was elaborated and included quality, price, and satisfaction as components influenced by competition from the consumers' perspectives. The model was validated using Structural Equation Modeling in SmartPLS. The sample was made up of 120 respondents and the sampling technique was quota. The structural model revealed that competition has a positive impact on satisfaction and explained 74% of its variance and also that competition has a positive impact on price and explained 7% of the variance. Moreover, using IPMA matrix analysis, the most powerful item of competition construct with an influence on satisfaction was the one related to the reputation of the private ophthalmology organization. Nonetheless, the key to gain competitive advantage stands in providing meaningful value to consumers using differentiation features such as high prices, reputation, and awareness on the services offered, greater availability, and the most important feature, innovation.

Retinal vein occlusion (RVO) is the second most common retinal vein disease with significant visual loss via thrombus or compression of vein wall. Thrombophilia is the predisposition to vascular thrombosis with the existence of genetic defect that leads to blood hypercoagulability. This report describes the case of a 55 year old male patient, with an active life who presented himself at the emergency room with acute visual lose, insidious and progressive visual field constriction, without any known history of neurological or vascular diseases. The examinations revealed unilateral optic nerve head edema, the fluorescein angiography was specific for nonischemic central retinal vein occlusion CRVO complicated with macular edema. Blood examinations has emphasized the presence of the heterozygous mutation A1298C in the methylenetetrahydrofolate reductase gene (MTHFR), the only one presented from the thrombophilia screen panel and a slightly elevated cholesterol level. During the follow-up period, the patient received anti-VEGF treatment (Bevacizumab, 3x 0.1 ml intravitreal injections) with improved visual acuity and amendment of macular edema. The complex etiology calls for interdisciplinary approach to determine better the cause of this ophthalmological disease. Although studies have found a correlation between some thrombophilia mutations and retinal vein occlusion, more studies that contain a larger number of patients are necessary in order to determine the final role of these gene variants.

Unlabelled: Selective laser trabeculoplasty--medium term efficacy and safety profile in open anlgle glaucoma or ocular hypertension treatment: SLT effect in reducing the intraocular pressure (IOP) in patients with open angle glaucoma or ocular hypertension.

Material and method: 70 eyes from 70 patients were included in the study in 2014 (12 months); the established design for this research was prospective and interventional. Patients received indication for SLT treatment as initial procedure or as adjuvant method in reducing the intraocular pressure when insufficient control with topical medication was noted. A single laser procedure was performed on 360 degrees. The result was verified and compared with baseline values of IOP at 1 month, 3 months respectively.

Results: IOP decreased at 1 month with 22.47% vs. baseline IOP and with 26.58% at 3 months. The IOP dynamics showed an additional 5.30% decrease between the intermediate and final values, with statistical significance for all the measured parameters (p = 0.001).

Conclusion: SLT applied on 360 degrees in a single session represents a safe and efficient procedure. The IOP decrease is marked at 1 month, but the effect continues until later, at 3 months interval after treatment. The higher the initial IOP was, the greater effect SLT has in decreasing the IOP level. Most frequently LST helps control the IOP, but rarely allows reducing or eliminating the glaucoma medication.

The purpose of this study is to review the current medical treatment and the new and better alternatives for patients with glaucoma. Glaucoma refers to a group of related eye disorders that have in common an optic neuropathy associated with visual function loss. It is one of the leading causes of irreversible blindness worldwide. Glaucoma can damage vision gradually so it may not be noticed until the disease is at an advanced stage. Early diagnosis and treatment can minimize or prevent optic nerve damage and limit glaucoma-related vision loss. Nowadays, research continues for the improvement of current medical treatment.

Iridocorneal endothelial (ICE) syndrome encompasses a group of rare ocular pathologies with unilateral involvement, frequently affecting young women. The disease complex includes essential iris atrophy, Chandler's syndrome, and Cogan-Reese syndrome. In the following article, we present a case of Iridocorneal endothelial syndrome in which a late diagnosis was made and who underwent surgery for advanced glaucoma.

This paper presents a few clinical cases of patients with high ametropies and/or anisometropia, who underwent one or two surgical procedures in our clinic, in order to obtain independence of glasses or contact lenses. Twenty cases of high ametropies were included in our study, with or without astigmatism, with transparent lenses, who presented in our clinic for surgical treatment to correct their refractive errors. Postoperatively, we analyzed the results and took decisions for each case in particular; sometimes a second surgical procedure was needed.
