HAS SNELLEN CHART LOST THE BATTLE TO ETDRS IN CATARACT SURGERY VISUAL ACUITY EVALUATION?

This study was designed to explore practical differences between visual acuity (VA) scores measured on Snellen chart ETDRS chart, to grade cataracts using LOCS III system, and to compare VA on both charts depending on cataract grade and type. Prospective evaluation of uncorrected and best-corrected visual acuity was carried out on the eye scheduled for cataract surgery preoperatively and postoperatively on the Snellen and ETDRS charts. The study was carried out at Department of Eye Diseases, Clinical Center of Serbia, during a two-year period.

Genetic Variations in Patients with Recurrent Herpes Simplex Keratitis.

: Recurrent herpes simplex keratitis (HSK) is the most common cause of corneal blindness in the developed world. A relationship between host gene polymorphisms and the recurrence of herpes simplex virus (HSV) infection has previously been proposed. Thus, the aim of this study was to investigate a potential association between the host genotype and recurrent HSK.

The evaluation of short- and long-term stability studies for brimonidine in aqueous humor by DPV/BDDE method-possible application for direct assay in native samples.

A novel voltammetric method was developed for brimonidine (BRIM) determination in deproteinized aqueous humor, simplifying preparation of biological samples for analysis for stability studies. The differential pulse voltammetric (DPV) method using boron doped diamond electrode (BDDE), based on characteristic oxidation peaks, was proposed and successfully applied. The linearity range was within 5.

Is the Use of Refrigerated Fixed Combination of Dorzolamide 2%-Timolol 0.5% (COSOPT) Associated with Less Ocular Discomfort: A Pilot Study.

Purpose: To test the hypothesis that the use of refrigerated fixed combination of dorzolamide 2% plus timolol 0.5% solution (COSOPT) is associated with less ocular discomfort compared with the use of this solution kept at room temperature.

Methods: In this prospective comparative study, 30 primary open-angle patients and 30 healthy subjects filled in the questionnaire on symptoms (Ocular Surface Disease Index) and subjective stinging feeling scale (1-10), at the start of study and 30 days after continuous use of refrigerated fixed combination or placebo eye drops.

Spectral analysis of intraocular pressure pulse wave in ocular hypertensive and primary open angle glaucoma patients.

Context: In attempt to find an alternative way to determine conversion from ocular hypertension to primary open angle glaucoma (POAG) (besides visual field and optic disc changes), we analyzed intraocular pressure (IOP) pulse wave in spectral domain.

Aims: The aim of this study was to test the potential differences in spectral content of IOP pulse wave between ocular hypertension and POAG patients, which could indicate conversion.

Settings And Design: Cross-sectional study designed to test the differences in the spectral content of pressure pulse wave between nontreated ocular hypertensive and nontreated, freshly diagnosed POAG patients.

Human external ophthalmomyiasis caused by Lucilia sericata Meigen (Diptera: Calliphoridae)--a green bottle fly.

Ophthalmomyiasis externa is the result of infestation of the conjunctiva by the larval form or maggots of flies from the order Diptera. If not recognized and managed appropriately, it can be complicated by the potentially fatal condition ophthalmomyiasis interna. Ophthalmomyiasis externa is mainly caused by the sheep bot fly (Oestrus ovis).

Influence of intravitreal injection of bevacizumab on systemic blood pressure changes in patients with exudative form of age-related macular degeneration.

Introduction: The aim of our study was to examine blood pressure (BP) changes in hypertensive and nonhypertensive patients after intravitreal bevacizumab injections and to assess whether intravitreal bevacizumab carries an associated vascular risk in patients with exudative ocular disease. We also aimed to estimate the influence of gender.

Methods: The study included 57 patients with age-related macular degeneration who received an intravitreal injection of 1.

Spectral analysis of intraocular pressure pulse wave in open angle glaucomas and healthy eyes.

Purpose: To investigate the spectral content of intraocular pressure (IOP) pulse wave by advanced spectral signal processing of continuous IOP readings obtained by dynamic contour tonometry.

Patients And Methods: A non-interventional case-control study included 20 healthy subjects, 20 previously untreated primary open angle glaucoma patients, and 20 previously untreated normal tension glaucoma patients. The continuous IOP reading obtained by dynamic contour tonometry was submitted to Fast Fourier Transform signal analysis and further statistical data processing.

Duane type I retraction syndrome associated with Wyburn-Mason syndrome.

Purpose: Our aim is to report the co-existence of Duane's retraction syndrome and Wyburn-Mason syndrome, a rare condition characterized by arteriovenous malformations (AVMs) in the central nervous system and retina.

Methods: An 11-year-old boy was referred for evaluation of strabismus present since birth. On examination his uncorrected visual acuity was 6/6 in each eye, with small angle left eye esotropia in the primary position, ipsilateral face turn, abduction deficit, lid fissure narrowing in adduction and widening in abduction; plus typical features of left-sided type I Duane syndrome were present.

Comparison of postoperative pain and satisfaction after dacryocystorhinostomy in patients operated on under local and general anesthesia.

Background: There has been only 1 study on postoperative pain after external dacryocystorhinostomy (DCR) that compared pain between 2 groups of patients; 1 group received local anesthesia and the other received general anesthesia. To further characterize the relationship between these 2 types of anesthesia and postoperative pain, we designed a study in which a single patient received these 2 different anesthesia modalities for a short interval on 2 different sides.

Material/methods: There were 50 participants in this study.

Pain during external dacryocystorhinostomy with local anesthesia.

Background: External dacryocystorhinostomy (DCR) is often performed under local anesthesia (LA) without adequate knowledge of the pain experienced by the patient.

Material/methods: We subdivided our surgical technique into stages easily understood by the patients (introducing cotton tipped applicators, performing parabulbar injection, creating the incision, bone cracking (opening the ostium), manipulating the nose, intubating, closing the wound, and packing with gauze). A total of 50 patients ranging in age from 31 to 83 years of age (63.

Is nail fold capillaroscopy useful in normotensive and primary open angle glaucoma? A pilot study.

Purpose: Vascular dysregulation is deemed a significant risk factor in glaucoma occurrence and progression. Capillaroscopy of the blood vessels on the finger nail-fold is a method that can provide information regarding the state of the vascular system at the capillary level. The aim of this pilot study was to determine whether there are significant differences in the morphological characteristics of the peripheral blood vessels in normotensive glaucoma and primary open angle glaucoma.
