Clinical outcomes and optical performance of four differentmultifocal intraocular lenses

Background/aim: The purpose of the present study was to evaluate clinical outcomes and optical performance of 4 different multifocal intraocular lenses (IOLs). Materials and methods: Ninety eyes of 51 patients who received Reviol MFM 611, Reviol MFM 625, Acri.LISA, and ReSTOR SN6AD3 multifocal IOLs after cataract surgery were retrospectively evaluated. The patients were similar in terms of age, sex, cataract hardness and axial length. The mean outcome measures were uncorrected and corrected distance visual acuity (UDVA, CDVA), distance-corrected intermediate and near visual acuity (DCIVA, DCNVA), intra or postoperative complications, and contrast sensitivity (CS) results under mesopic conditions. The mean follow up period was 10.5 months (range: 6 12 months). Results: All cases were within ± 0.75 D of emmetropia. Postoperative increase in UDVA and DCNVA was statistically significant in all groups. The Acri.LISA group showed slightly lower DCIVA compared with the other IOLs. CS was clinically similar between the groups. None of the patients developed any early or late postoperative complication or neuroadaptation problem, which necessitated explantation of the lens. Conclusion: All four multifocal lens designs provided satisfactory visual functions and CS results in patients who fulfilled the criteria for multifocal lens implantation

Nodular Scleritis and Sweet Syndrome

Sweet’s syndrome (Acute febrile neutrophilic dermatosis) is a rare skin disorder characterized by fever, neutrophilic leucocytosis, and erythematous skin nodules. Patients are usually middle-aged women presenting with painful skin lesions. This syndrome is known to have extra-cutaneous manifestations involving the joints, kidneys, liver, and lungs. In this article, the authors aim to present a case of Sweet’s syndrome with ocular involvement. (Turk J Ophthalmol 2013; 43: 286-8

Evaluation of Macular Thickness and Retinal Nerve Fiber Layer by Optical Coherence Tomography in Cases with Strabismic and Anisometropic Amblyopia

Pur po se: To measure the macular and retinal nerve fiber layer (RNFL) thicknesses using optical coherence tomography (OCT) in amblyopic eyes of unilateral strabismic and anisometropic patients and to compare the results with those of their normal eyes and with a control group. Ma te ri al and Met hod: 30 strabismic and 30 anisometropic amblyopic patients who were followed by Atatürk Training and Research Hospital Strabismus section between September 2009 and February 2010 and 30 healthy children who were examined in the out-patient clinic were included in the study. The amblyopic eyes of the amblyopic patients were compared with their normal eyes andwith the right eyes of the healthy patients. After detailed ophthalmologic examination, macular thickness, central foveal, parafoveal and perifoveal volumes and RNFL thickness of the cases were measured with OCT and compared statistically. A p-value of less than 0.05 was accepted as statistically significant. Re sults: Foveal volume of the amblyopic eyes of strabismic and anisometropic amblyopic cases (0.20mm3; 0.21mm3, respectively) was statistically higher than in the control group (0.19 mm3) (p=0.002).As the level of amblyopia increased, there was an increase in foveal volume. Central foveal thickness (CFT) of the amblyopic eyes of strabismic and amblyopic patients (258 μm and 260 μm, respectively) was higher than in the control group (244 μm), which was statistically significant difference (p=0.010). Similarly, as the level of amblyopia increased, there was an increase in CFT. When strabismic and amblyopic cases were compared, no statistical difference was observed between foveal volumes (central-parafoveal-perifoveal) and CFT results (p>0.05). There was no difference in RNFL thickness of strabismic, anisometropic and control cases (p>0.05). In addition, no significant difference was detected between the normal eyes of the amblyopic patients and the control group (p>0.05). Dis cus si on: Although the primary site of deficit is in the visual cortex in amblyopia, secondary changes occur in the retina as well. While RNFL thickness does not differ from that in normal eyes, the thickness and volume of the fovea of amblyopic eyes are higher than in normal individuals. As a result, amblyopia not only affects the visual cortex, but gives rise to secondary changes at retinal level. (Turk J Ophthalmol 2011; 41: 318-24

Evaluating of Tear Meniscus Parameters with Optical Coherent Tomography in Dry-Eye Patients

Purpose: To evaluate the changes in meniscus parameters with optical coherence tomography (OCT) after treatment and consider the correlation between the OCT parameters and dry-eye tests. Material and Method: Thirty-two dry-eye patients and 30 healthy individuals were included. Visual acuities, biomicroscopic evaluation, Schirmer-I test, tear-break-up time (T-BUT), and lower-tear meniscus parameters measured with OCT were evaluated. Ocular surface disease index (OSDI) was performed. The measurements were repeated on the 10th day and 1st month of the treatment. Lower tear meniscus height (LTMH), depth (LTMD), area (LTMA) and α-angle were measured. The tear meniscus parameters of the dry-eye group were compared with the control group before treatment, and the correlation between the dry-eye tests and OCT measurements were evaluated. The change in the results of the dry-eye tests and OCT measurements with treatment were assessed. Results: There was statistically no significant difference between the age and gender of the patients in groups. Before treatment the mean Schirmer-I test, TBUT and OSDI scores were different. The LTMH and LTMA were higher in the control group. In the dry-eye group before treatment, there was a negative correlation between the OSDI score and OCT parameters, however, no meaningful correlation was observed between any other test and OCT parameters. Although there were no change in LTMD and α-angle with treatment, the 1st month values of LTMH and LTMA were significantly higher from the pre-treatment and 10th day values. Discussion: When diagnosing dry-eye, TBUT and OSDI scores were found to be more effective compared to Schirmer-I test for the diagnosis of dry eye. Although not adequate by itself, tear meniscus parameters measured with OCT, LTMH and LTMA, may be helpful for evaluating the efficacy of treatment, and the correlation of these two parameters with the OSDI score may increase the objectivity while questioning the symptoms.
