Retinal nerve fibre layer thickness measurements in myopia by optical coherence tomography
Aim: Our study aimed to evaluate through OCT, in a homogeneous group of subjects with various degrees of myopia, the macular thickness and that of the RNFL with the purpose of highlighting the possible presence of a correlation between their impairment and the degree of myopia. Material and Methods : 83 students of the Faculty of Medicine were considered, distinguished into 4 groups, 3 of them according to the degree of myopia and the last group (control group) was made of emmetropic subjects. Each subject was submitted to a determination of visual acuity and refractive defect and evaluation of the thickness of the macular fibres and of the retinal nerve fibre layer (RNFL) through OCT (Stra…
Optic neuropathy caused by type A botulinic toxin
Purpose To report the development of an optical neuropathy after injection of type A botulinic toxin in a subject with blepharospasm. Methods Optical neuropathy was evaluated through a complete ophthalmologic examination consisting of bio-microscopy, tonometry and study of visual sharpness, colour test, visual field, OCT, fluorangiography and determination of VEPs. Results Intravenous therapy was begun with Metilprednisolone (20 mg/Kg/day) and Vitamin B6 associated with oral Citicoline, and there was a clear improvement down to normalization of the symptoms. After 6 months the Humphrey computerized visual field with central 30-2 program threshold test emphasised in ODx an upper half-field a…
Retinal myelinated nerve fibers associated with macular pseudohole
We report the case of a 24-year-old woman who presented unilateral extensive peripapillary myelinated nerve fibers associated with macular pseudohole and bilateral low myopia. Visual acuity, slit lamp biomicroscopy, automated perimetry, fundus color photography, and optical coherence tomography (Stratus® OCT) were performed. We discuss the clinical findings and diagnostic details of unilateral extensive peripapillary myelinated nerve fibers associated with macular pseudohole.
Variazione della pressione intraoculare durante le procedure diagnostiche endoscopiche
Obiettivo. Obiettivo del presente studio è stato quello di rilevare qualsiasi possibile variazione nella pressione intraoculare (PIO) in soggetti non glaucomatosi sottoposti a esami endoscopici come la gastroscopia o la colonscopia, al fine di valutare il ruolo della tensione mentale in tali cambiamenti. Metodi. La frequenza cardiaca e il tono oculare sono stati misurati prima e subito dopo le procedure endoscopiche e 30’ dopo la somministrazione di un antagonista delle benzodiazepine in 100 soggetti, 52 uomini e 48 donne, sottoposti a gastroscopia, colonscopia o entrambi gli esami nella stessa occasione. Risultati. La frequenza cardiaca è diminuita da 82,10±14,41 a 76,11±10,96 30’ dopo la …
