This paper presents an improved co-evolution genetic algorithm (ICGA), which uses the methodology of game theory to solve the mode deception and premature convergence problem. In ICGA, groups become different players in the game. Mutation operator is designed to simulate the situation in the evolutionary stable strategy. Information transfer mode is added to ICGA to provide greater decision-mak...

Skin flap vascularity is a critical determinant of aesthetic results in autologous ear reconstruction. In this study, we investigate the use of intraoperative laser-assisted indocyanine green angiography (ICGA) as an adjunctive measure of skin flap vascularity in pediatric autologous ear reconstruction. Twenty-one consecutive pediatric patients undergoing first-stage autologous total ear recons...

Purpose To describe management of residual branch vascular network (BVN) in polypoidal choroidal vasculopathy (PCV) by thermal laser photocoagulation of feeder vessel. Observations Case report of sixty-four year old female with polypoidal choroidal vaculopathy (PCV) with moderate response to seven doses of intravitreal ranibizumab, six doses of intravitreal bevacizumab and one session of phot...

AIMS Drusen are rarely observed in patients < 50 years of age. Two types of early onset drusen (EOD) are commonly described: basal laminar drusen (BLD) and drusen associated with Malattia Leventinese (ML). Our purpose was to classify the phenotype of EOD on the basis of fundus examination, and fluorescein angiography (FA) and indocyanine green angiography (ICGA) features. METHODS We performed...

Purpose To determine the prevalence of subclinical nonexudative neovascularization and associated choroidal vascular changes in the fellow eyes of patients presenting with unilateral typical exudative AMD (tAMD) or polypoidal choroidal vasculopathy (PCV) using indocyanine green angiography (ICGA) and swept-source (SS) optical coherence tomography angiography (OCT-A). Methods We recruited pati...

Purpose The purpose of this study was to compare optical coherence tomography angiography (OCTA) and indocyanine green angiography (ICGA) for the assessment of corneal neovascularization (CoNV). Methods Patients with CoNV extending at least 3 mm into the cornea were included. All patients underwent corneal imaging at the same visit. Images were recorded using the AngioVue OCTA system (Optovue...

Aim: To evaluate and compare the fluorescein (FA) and indocyanine green angiographic (ICGA) findings, and to investigate the choroidal involvement in Behçet’s disease. Methods: FA and ICGA were performed on 112 eyes of 62 patients with Behçet’s disease, between November 1993 and July 2002, using Topcon IMAGEnet Digital System. Patients were aged 16–50 years; 48 (77.4%) were male and 14 (22.6%) ...

Aims and Background: Compromise in blood supply and failure in tissue transfer are associated with excessive resource costs in plastic surgery. The ability to detect impaired blood supply on the table would contribute to major cost savings for the health care system. Indocyanine green imaging (ICGA) holds promise as a simple method with a high sensitivity and specificity for assessing blood flo...

AIM To observe the choroidal microstructure in polypoidal choroidal vasculopathy (PCV) using high-penetration optical coherence tomography (HP-OCT) with a long-wavelength light source that visualises tissue beneath the retinal pigment epithelium (RPE) and deep choroid, and to compare the findings with those of indocyanine green angiography (ICGA). METHODS In this retrospective, non-invasive, ...

PURPOSE To assess the respective involvement of retina versus choroid in presumed ocular tuberculosis (POT) in a non-endemic area using dual fluorescein (FA) and indocyanine green angiography (ICGA). METHODS We retrospectively analyzed cases diagnosed with POT at the Centre for Ophthalmic Specialized Care, Lausanne, Switzerland. Angiography signs were quantified using an established dual FA a...
