The role of inflammation in age-related macular degeneration (AMD) is well documented and the association of AMD with the inflammatory marker C-reactive protein (CRP) and members of the complement system underline the role of complements in AMD. Human complement factor...
Macular pigment and dark adaptation in older population with normal maculas

EYE - Vitreo-Retinal
Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

EYE - Neuro-ophthalmology
This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
Choroidal changes after horizontal strabismus surgery
The aim of this study was to investigate choroidal changes in the short-term by looking at the choroidal vascular layer after horizontal strabismus surgery. This was a retrospective study of 27 patients: 12 females and 15 males with mean age...The management of chronic central serous chorioretinopathy

Chorioretinal or choroidal folds are parallel striations involving the retina, retinal pigment epithelium (RPE), Bruch’s membrane, and inner choroid [1]. They can arise from compressive stress on these layers, and their presence often serves as a diagnostic marker for underlying...

EYE - Neuro-ophthalmology
This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...
The treachery of images – making sense of OCT imaging
In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...What’s next in retinal imaging? Faster, deeper and full-on
Fast-evolving technological leaps are opening the way toward clinically useful ocular coherence angiography, generating 3-dimensional microvasculature maps without intravenous dye injection, as well as whole-eye imaging, handheld patient-operated optical coherence tomography (OCT) devices and, for challenging vitreoretinal procedures, integrated intraoperative...Neurofibromatosis with multiple bilateral choroidal nevi and literature review

The aim is to present a case of neurofibromatosis type-1 (NF-1), also known as von Recklinghausen disease, who presented with bilateral multiple choroidal nodular nevi following chemotherapy and mastectomy for breast cancer. Neurofibromatosis type-1 presents as a wide range of...
25 years of OCT
David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...
