With 6-man Chess essentially solved, the available 6-man Endgame Tables (EGTs) have been scanned for zugzwang positions where, unusually, having the move is a disadvantage. Review statistics together with some highlights and positions are provided here: the complete information is available on the ICGA website. An outcome of the review is the observation that the definition of zugzwang should b...

PURPOSE To evaluate peripapillary acute zonal occult outer retinopathy in a 67-year-old man. METHODS Images were obtained using fundus photography, fluorescein angiography (FA) and indocyanine green angiography (ICGA), fundus autofluorescence (FAF) imaging, and optical coherence tomography (OCT). Visual field testing and multifocal electroretinogram (mfERG) were also performed to evaluate ret...

PURPOSE To report the effect of subthreshold transpupillary thermotherapy (TTT) in treating serous detachment of the neurosensory retina secondary to chronic central serous chorioretinopathy (CCSC). METHODS Seven eyes from five patients with CCSC, persistent serous detachment of the neurosensory retina and a clinical course of between 12 and 60 months were treated. All eyes received large-spo...

This study investigated the efficacy of multiple intraoperative monitoring techniques including indocyanine green angiography (ICGA), somatosensory evoked potential (SSEP) and motor evoked potential (MEP) in the clinical outcome of microneurosurgical treatment for anterior circulation cerebral aneurysm. Fifty-two anterior circulation cerebral aneurysms (Hunt and Hess [H&H] grades 0, 1 or 2) fro...

Purpose. To investigate the prevalence and characteristics of focal choroidal excavation (FCE) concurrent with central serous chorioretinopathy (CSC) using multimodal imaging. Methods. This was a retrospective single-institution study. Clinical features and multimodal imaging findings were analyzed in eyes with CSC and FCEs, using imaging methods including optical coherence tomography (OCT), OC...

Purpose: To evaluate the short-term efficacy of intravitreal anti-VEGF (Lucentis) and sub-tenon injection of triamcinolone acetonide for choroidal neovascularization (CNV) associated with multifocal choroiditis (MC). Methods: Eight eyes of 8 patients treated with intravitreal anti-VEGF and posterior sub-tenon injection of Triamcinolone Acetonide (TA) for subfoveal or juxtafoveal CNV associated ...

PURPOSE To describe a case of choroidal osteoma with choroidal neovascularization (CNV) that was successfully treated with two intravitreal injections of bevacizumab (IVB). DESIGN AND METHODS Case report on a 12-year-old Japanese girl who presented with a sudden decrease in vision in her left eye. At the first visit, 2 days after the onset of her symptoms, her visual acuity (VA) in her left e...

The optical coherence tomography (OCT) and indocyanine green angiography (ICGA) findings of a 58-year-old male with acute syphilitic posterior placoid chorioretinitis are reported herein. Best-corrected visual acuity was 20/150 in the right eye (OD) and 20/30 in the left eye (OS) at presentation. On funduscopy, there was a central subretinal placoid yellowish lesion in OD. VDRL and serum FTA-AB...

Purpose To assess the occurrence of choroidal neovascularization (CNV) secondary to chronic central serous chorioretinopathy (CSCR) using optical coherence tomography angiography (OCTA) and correlate these findings with choroidal thickness (CT). Materials and Methods This retrospective study included 25 consecutive patients (43 eyes), mean age 48.12 ± 7.8 years, diagnosed with persistent CSCR...

Purpose We investigated the application of contrast-enhanced ultrasound (CEUS) to quantify vascular perfusion in two animal models of choroidal melanoma. Methods B16F10 and choroidal melanoma cell line (OCM1) melanoma xenografts were implanted into the cyclodialysis cleft of rabbits' right eyes. Fundus photography, indocyanine green angiography (ICGA), B-mode ultrasound, and CEUS were used to...
