Purpose: This multicenter, epidemiological, cross-sectional study aimed to estimate the annual cumulative incidence of major macular diseases that cause visual impairment and require therapeutic intervention in the routine care of Greece.
Methods: The study was carried out between December 2012 and May 2015 in 20 ophthalmology clinics. Over a one-year recruitment period per study site, all treatment naïve adult patients newly diagnosed with wet age-related macular degeneration, visual impairment due to diabetic macular edema or macular edema secondary to retinal vein occlusion requiring therapeutic management and who had not been diagnosed or treated for the same disease in the past were enrolled after providing informed consent.
To compare surgically induced astigmatism (SIA) of different surgeons, who perform the same main incision. Two hundred and seventy eyes underwent cataract surgery with phacoemulsification by four different surgeons (A, B, C, and D). A 3-step, 3.

Capsular bag distension syndrome is a very rare complication of cataract surgery. Most cases occur after uneventful phacoemulsification with continuous curvilinear capsulorhexis and implantation of an intraocular lens in the capsular bag. The entity presents with reduction of visual acuity and myopic shift in the early-to-late postoperative period.

During pregnancy seroconversion occurred and positive titers of antitoxoplasmic antibodies (immunoglobulin M and G) were found in the mother, in the third trimester. She received treatment with spiramycin.

Due to the severity of the underlying disease, it was not possible to reduce the corticosteroid dose. After initial unsuccessful treatment with an intravitreal injection of ranibizumab, low-fluence photodynamic therapy was performed, followed by gradual tapering of the corticosteroids.

In this study, we validate a novel lysyl oxidase-like 1 (LOXL1) genotyping method, investigate the previously reported association of LOXL1 with XFS/XFG, and evaluate apolipoprotein E (APOE) and methylenetetrahydrofolate reductase (MTHFR) polymorphisms as genetic risk factors for both conditions in our population.
Methods: Blood samples were collected from 82 patients with XFG, 69 patients with XFS, 52 patients with primary open-angle glaucoma (POAG), and 107 controls.
Background And Objective: To investigate the morphological substrate of the changes in visual function in eyes with retinitis pigmentosa and good visual acuity using spectral-domain optical coherence tomography (SD-OCT).
Patients And Methods: A total of 30 eyes of 17 patients with retinitis pigmentosa and visual acuity of 20/40 or better underwent contrast sensitivity and color vision testing. The retinal thickness at the fovea and macula and the length of the photoreceptor inner/outer segment (IS/OS) junction were assessed by SD-OCT.
Background And Aims: Extraintestinal manifestations of inflammatory bowel disease (IBD) can involve the orbit and the optic nerve. Although these manifestations are rare, they can be particularly serious as they can lead to permanent loss of vision. The aim of the review is to present the existing literature on IBD-related optic nerve and orbital complications.

Patients And Methods: Two patients with conjunctival tumors were examined and treated in the University Eye Clinic and diagnosed in the University Pathology Department, University Hospital of Ioannina, Greece. The first patient was a 48-year-old man presenting with an extended papillomatous lesion in bulbar conjunctiva covering part of the cornea of his right eye.
Purpose: To present various forms of uveitis and/or retinal vasculitis attributed to Bartonella infection and review the impact of this microorganism in patients with uveitis.
Methods: Retrospective case series study. Review of clinical records of patients diagnosed with Bartonella henselae and Bartonella quintana intraocular inflammation from 2001 to 2010 in the Ocular Inflammation Department of the University Eye Clinic, Ioannina, Greece.
Purpose: Evaluation of contrast sensitivity in patients with beta-thalassemia major and sickle cell disease which undergo regular transfusions and chelation therapy with desferrioxamine (DFX).
Materials And Methods: We studied contrast sensitivity in 48 eyes (24 patients) with beta-thalassemia major (group A) and in 42 eyes (21 patients) with sickle cell disease (group B), compared to 60 eyes of 30 healthy individuals (control group). Contrast sensitivity was measured using B-VAT II-SG Mentor Video Aquity Tester.
Purpose: To present the technique of a modified deep sclerectomy, which we will call "reversed" deep sclerectomy (RDS) and the results and our observations of its use in patients with open angle glaucoma (OAG) and with or without cataract extraction (phacoemulsification).
Materials And Methods: This prospective study included 132 eyes which underwent RDS: 37 eyes (group A) with uncontrolled OAG and 95 eyes (group B) with OAG and visually significant cataract. Mean pressure preoperatively for group A was 24.
Purpose: To determine whether the removal of the inner wall of Schlemm's canal (external trabeculectomy) improves the effectiveness of a modified method of deep sclerectomy (DS), which we will call "reversed" deep sclerectomy (RDS).
Materials And Method: We conducted a prospective study of two groups of patients. Group A included 22 eyes of 18 patients with open angle glaucoma (OAG) under maximum medical treatment, which underwent RDS - a modified method of performing DS - with the removal of the inner wall of Schlemm's canal (external trabeculectomy) and without using any implant.
Objective: To evaluate the characteristics and visual prognosis of juvenile idiopathic arthritis-associated uveitis (JIA).
Methods: A retrospective review was performed on 56 patients who met the criteria for JIA to identify those with uveitis and related complications. Patients were referred to and were examined in the Pediatric Department of the University Hospital of Ioannina, between 1995 and 2007.
Introduction: Cavernous hemangiomas of the orbit are benign vascular malformations, commonly encountered in adults. Although they are infrequent in pediatric population their diagnosis and course are of a great significance, mainly because they can cause visual disturbances such as amblyopia that can ensue, and secondarily due to their cosmetic and psychological effect. Special attention is required in follow up and treatment.

Methods: Phacoemulsification was performed in 22 rabbit eyes, and two different IOL types (Acrysof SA60 AT and Akreos Disc) were implanted. These IOLs had the same optic geometry (square edged) but different material and design.
Background: Protein Z is a glycoprotein that acts as a co-factor for the inhibition of activated coagulation factor X. Protein Z circulating in abnormal levels has been associated with increased risk for acute ischemic events. Non-arteritic Anterior Ischemic Optic Neuropathy (N-AION) is caused by acute ischemic infarction of the optic nerve head, supplied by the posterior ciliary arteries.

Primary non-Hodgkin's lymphomas of the conjunctiva are uncommon. They are almost exclusively extranodal marginal zone B-cell lymphomas/mucosa-associated lymphoid tissue lymphomas. In this study, we report an extremely rare case of conjunctival mantle cell lymphoma in a 78-year-old man, presenting as a unilateral epibulbar mass.

Methods: Fifty-two surgically excised pterygia and seven normal conjunctivae were immunohistochemically studied applying the streptavidin-biotin method in paraffin-embedded tissue sections.
Purpose: To assess implantation of an Artisan aphakic intraocular lens (IOL) in cases with subluxated lenses due to Marfan syndrome.
Methods: Retrospective study of a small case series comprised of seven eyes (two children and three adults) with subluxated lenses due to Marfan syndrome that underwent lens extraction and Artisan aphakic IOL implantation. Best spectacle-corrected visual acuity and endothelial cell status were the key elements of follow-up examinations.
