PURPOSE To evaluate the validity of a novel fully automated three-dimensional (3D) method capable of segmenting the choroid from two different optical coherence tomography scanners: swept-source OCT (SS-OCT) and spectral-domain OCT (SD-OCT). METHODS One hundred eight subjects were imaged using SS-OCT and SD-OCT. A 3D method was used to segment the choroid and quantify the choroidal thickness ...

Two patients with multifocal choroiditis similar or identical to POHS are presented. Colour photographs and fluorescein angiography document the occurrence of de novo lesions in the originally involved eye. The cases also demonstrate the development of new choroidal lesions within the originally involved eye, the early evolution of the "basic choroidal lesion", and the need for fluorescein angi...

Evolution of an osteoma may result in neurosensory detachment, deossification, and choroidal neovascularization (CNV). The authors report a rare case of choroidal osteoma with CNV associated with a deep non-conforming focal choroidal excavation. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:944-947.].

Choroidal melanoma is one of the most malignant tumors organ vision, development which associated with risk metastasis and possibility death, indicates relevance search application effective methods treatment this pathology. To date, in choroidal melanoma, preference given to organ-preserving aimed at achieving local control over tumor. One promising techniques photodynamic therapy, a method ba...

Age-related macular degeneration (AMD) is a major cause of irreversible blindness. Choroidal structural changes seem to be inevitable in AMD pathogenesis. Our study revealed associated choroidal microstructural changes in AMD eyes.The aim of the study was to compare choroidal microstructural changes in eyes with AMD of different stages.The study was a retrospective, cross-sectional case series....

We studied the possible role of the choroidal circulation in stabilizing the temperature environment of the retina and the retinal pigment epithelium. Temperature measurements were taken from the retina and choroid of the monkey eye while the ambient illumination and choroidal blood flow were varied. The results showed that the choroidal circulation plays a significant role in dissipating heat ...

PURPOSE To update the findings from the Choroidal Neovascularization Prevention Trial (CNVPT) with respect to resolution of drusen, incidence of choroidal neovascularization, and visual function. DESIGN A multicenter, randomized, controlled, pilot clinical trial. PARTICIPANTS The 120 patients enrolled in the CNVPT. Patients had signs of choroidal neovascularization or retinal pigment epithe...

In ophthalmology, as in medicine generally, there has been a rapid development of treatment to combat infections and allergic conditions, but the choice of therapy for degenerative, hereditary conditions is-admittedly-just as small as before. The proportionate role played by the genetic degenerative eye lesions as causative factors of blindness, or impaired vision, has thus greatly increased. R...

Papadopoulou et al are to be congratulated for submitting an informative article regarding the management of small choroidal melanoma with pertinent discussion and various educational points to remember. We were, however, surprised, not to find the use of OCT (optical coherence tomography) as part of the management to help the diagnosis or in the discussion section. The authors correctly highli...

PURPOSE To study the changes in the choroidal layers thickness with age in a healthy population using swept-source optical coherence tomography. METHODS Retrospective data analysis of a subgroup of eyes from a previous single-center, prospective, cross-sectional, noninterventional study. One hundred and sixty-nine healthy eyes were evaluated using swept-source optical coherence tomography. In...
