Foveal and Extrafoveal Effects of Half-Dose Photodynamic Therapy in Chronic Central Serous Chorioretinopathy: A Cohort Study.

Purpose: To compare the efficacy and safety of foveal and extrafoveal half-dose photodynamic therapy (HD-PDT) for chronic Central Serous Chorioretinopathy (cCSC).

Methods: This retrospective, cohort study included cCSC eyes submitted to HD-PDT on foveal (F) or extrafoveal (E) areas. Patients were evaluated at baseline and 12 weeks after treatment for best corrected visual acuity (BCVA) and the following spectral-domain optical coherence tomography (SD-OCT) subfoveal parameters: central macular thickness (CMT), outer nuclear layer, external limiting membrane, ellipsoid zone, interdigitation zone, choroidal thickness and subretinal fluid (SRF).

Anatomical and functional results of ILM peeling vs. non-peeling in macula-off rhegmatogenous retinal detachment.

Purpose: To compare anatomical and functional results between internal limiting membrane (ILM) peeling and non-ILM peeling in macula-off rhegmatogenous retinal detachment (RRD).

Methods: We completed a retrospective cohort study of patients who underwent pars plana vitrectomy (PPV) due to macula-off RRD. ILM peeling (P) versus non-ILM peeling (NP) groups were compared regarding best-corrected visual acuity (BCVA), anatomical success, endotamponade, concomitant scleral band placement and BCVA gain for epiretinal membranes (ERM) resubjected to PPV.

Outer retinal layers as predictors of visual acuity in retinitis pigmentosa: a cross-sectional study.

Purpose: To evaluate the integrity of the outer retinal layers-outer nuclear layer (ONL), external limiting membrane (ELM), ellipsoid (EZ), and interdigitation band (IZ)-using spectral-domain optical coherence tomography and estimate their effect on visual acuity in retinitis pigmentosa (RP).

Methods: A cross-sectional study was performed in the Ophthalmology Department of Hospital de Braga, Portugal. Patients with RP followed in the Hospital de Braga during January to August 2017 were included.

Ophthalmologic Manifestations of Wolfram Syndrome: Report of 14 Cases.

Purpose: The aim of this study was to describe ophthalmological abnormalities in 14 cases of Wolfram syndrome belonging to 9 different families.

Methods: Patients were submitted to a complete ophthalmological, neurological, otorhinolaryngological, urological, and genetic evaluation.

Results: Our sample comprised 14 Caucasian patients belonging to 9 different families.

Functional impairment with minimal macular damage in femtosecond laser plasma injury: case report.

A 26 years old female patient was examined twenty-four hours after observing laser-induced plasma formation in a process of nanoparticle production complaining of bilateral central scotoma. The ophthalmologic evaluation included dilated fundus observation, fluorescein angiography, and optical coherence tomography (OCT). In the first assessment, visual acuity was 20/20 in the right eye and 20/25 in the left eye.
