Perceptual distortion in homonymous paracentral scotomas.

Background: Cortical remapping after peripheral or central visual deafferentation alters visual perception, but it is unclear whether such a phenomenon impinges on areas remote from a scotoma. To investigate this question, we studied variations of perceptual spatial distortion in the visual field of patients with homonymous paracentral scotoma.

Methods: Two patients with right inferior homonymous paracentral scotoma were asked to describe their perception of a series of figures showing two isometric vertical lines symmetrically located on either side of a fixation point.

Bilateral multifocal retinal pigment epithelium detachments associated with systemic corticosteroids.

Purpose: To report an unusual case of central serous chorioretinopathy (CSC), presenting as bilateral and multifocal isolated serous retinal pigment epithelium detachments (RPEDs) following corticosteroid treatment.

Methods: An otherwise healthy 39-year-old man was evaluated for visual loss following blunt trauma of his right eye (RE). The patient underwent complete bilateral ophthalmologic examination, including optical coherence tomography and fluorescein (FA) and indocyanine green angiography (ICGA).

[OCT Visante observation of the progression of a perforated neurotrophic cornea ulcer treated with amniotic membrane grafts].

Introduction: The optical coherence tomography (OCT) Visante provides easy, high-resolution observation free of contact with the cornea and anterior segment. We present the progression of a neurotrophic corneal ulcer treated with amniotic membrane grafts studied with this system.

Methods: A 71-year-old patient with facial nerve paresis secondary to vestibular schwannoma surgery presented with a neurotrophic perforated corneal ulcer.

[Evaluation of the anterior chamber depth after cataract surgery with OCT Visante].

Introduction: OCT Visante allows the visualisation of the anterior segment structures and particularly of the irido-corneal angle by a non-contact method. We made a prospective study on 14 patients to demonstrate by OCT Visante the changes of irido-corneal angle and depth of the anterior chamber after cataract surgery.

Patients And Methods: 14 eyes of 14 patients have undergone a phacoemulsification of the cataract with posterior chamber lens implantation.

Primary vitrectomy without scleral buckling for pseudophakic rhegmatogenous retinal detachment.

Purpose: To report the anatomic and functional results of primary vitrectomy without scleral buckling for the treatment of pseudophakic rhegmatogenous retinal detachment (PsRD).

Design: Prospective, nonrandomized surgical technique study.

Methods: One hundred eyes of 98 patients with PsRD were operated by vitrectomy alone.
