PURPOSE To investigate the anatomic and electrophysiologic changes of the macula and the optic nerve in patients with Parkinson disease (PD) without visual impairment. METHODS Thirty-two eyes of 16 patients with PD (group A) without visual impairment were tested. Visual acuity was 20/20 or better and visual fields as well as color vision testing results(More)
Purpose To evaluate retinal thickness and function in eyes with tilted disc syndrome with optical coherence tomography (OCT) and multifocal electroretinogram (mfERG). Methods Twenty-one eyes of 12 patients (4 males and 8 females) with tilted disc were studied with OCT3 and mfERG and compared with 40 eyes of 20 age and sex-matched control subjects. The(More)
We report a case of simultaneous bilateral nonarteritic anterior ischemic optic neuropathy (NAION) due to sildenafil use. A 55-year-old man with an unremarkable medical history presented simultaneous bilateral NAION 8 months after continuous use of sildenafil 4-5 times a month. At presentation, visual acuity (VA) was 0.7 in the right eye (RE) and 0.9 in the(More)
BACKGROUND   The aim was to evaluate the correlation between the anatomical and functional outcomes before and after treatment of uveitic macular oedema. METHODS   Thirty-three eyes of 33 patients with uveitic macular oedema were included in the present study. Visual acuity (VA), optical coherence tomography (OCT) and multifocal electroretinogram (mfERG)(More)
PURPOSE To report our results and to evaluate the longterm effect of capsular tension ring (CTR) insertion in eyes with large traumatic zonular dialysis that underwent phacoemulsification with posterior chamber (PC) intraocular lens (IOL) implantation. METHODS This prospective study included 17 eyes of 17 consecutive patients with cataract and large(More)
BACKGROUND The aim was to evaluate the macular structure and function in children with human immunodeficiency virus (HIV) disease without cytomegalovirus retinitis or visual symptoms. METHODS Thirty-eight eyes of 19 HIV-positive children (Group A) were examined. Group B included 20 (40 eyes) age- and sex-matched control subjects. Each individual underwent(More)
PURPOSE To investigate multifocal visual evoked potentials (mfVEP) of the amblyopic and fellow eye in amblyopia due to anisometropia. METHODS We recorded mfVEP in both eyes of 15 anisometropic amblyopic patients and 15 normal control subjects. The responses from the central 7.0 degrees arc of the visual field were measured, and changes in latency and(More)
We report a case of a human leukocyte antigen B27 (HLA-B27)-negative patient with cystoid macular edema (CME) and ankylosing spondylitis (AS) after treatment with triamcinolone acetonide. The patient complained of deterioration of visual acuity of the right eye during the last 10 days. At presentation visual acuity of the right eye was 0.2, and the(More)
Purpose To report a case of a tilted disc syndrome associated with choroidal neovascularization. Methods A 55-year-old male patient presented with blurred vision and metamorphopsia of the left eye. He underwent complete ophthalmologic examination, fluorescein angiography, optical coherence tomography (OCT) and multifocal-electroretinogram (mf-ERG). Results(More)
We report three subjects of a Greek family affected by triple A syndrome (AAAS). All patients underwent complete ophthalmic examination, full-field electroretinogram (ERG), visual evoked responses (VER), optical coherence tomography (OCT) and molecular analysis of the AAA gene. All patients had alacrima. In two of them, the proband and her brother,(More)
