Patient Information

Choroidal neovascularization in high myopia is one of the most feared ocular complications in highly myopic patients. Dr Julien Gozlan, an ophthalmologist and surgeon specializing in retinal diseases at Cabinet Ophtalmologique Paris – Auteuil, manages this macular condition using state-of-the-art diagnostic equipment including OCT and OCT angiography. This article details the pathophysiological mechanisms of myopic choroidal neovascularization, its symptoms, current diagnostic methods, treatment with intravitreal anti-VEGF injections, and long-term visual prognosis.

Retinal artery occlusion is an ophthalmological emergency characterised by sudden loss of vision, comparable to a stroke of the eye. This rare but serious condition results from the interruption of blood flow in an artery supplying the retina, causing ischaemia that can lead to irreversible damage within hours. Dr Julien Gozlan, retina specialist at Cabinet Ophtalmologique Paris – Auteuil, explains in this article the different forms of retinal artery occlusion, their causes, warning symptoms, diagnostic examinations performed (fundus examination, OCT, OCT angiography), emergency management, visual prognosis and the critical importance of the associated cardiovascular workup.

The pachychoroide spectrum encompasses a set of ocular pathologies sharing common abnormalities of the choroid, this vascular nourishing layer located beneath the retina. First described in 2013, this concept has profoundly changed our understanding of many retinal diseases. Dr Julien Gozlan, an ophthalmologist specializing in retinal diseases at Paris – Auteuil Ophthalmology Practice, offers you in this article a clear and accessible explanation of what pachychoroide is, the different pathologies that make up this spectrum, the examinations necessary for diagnosis and the available treatments.

Angioid streaks are a rare but potentially serious ocular condition caused by breaks in Bruch's membrane at the back of the eye. Dr Julien Gozlan, ophthalmic surgeon specializing in retinal diseases in Paris 16, regularly sees patients affected by this condition. In this article, we explain in simple terms what angioid streaks are, their causes, the symptoms that should raise concern, the examinations required for diagnosis, and the treatments available today to preserve your vision.

PAMM (Paracentral Acute Middle Maculopathy) is a recently identified ischemic retinal condition affecting the intermediate layers of the macular retina. Dr Julien Gozlan, ophthalmic surgeon specializing in retinal diseases and surgery in Paris 16, provides a comprehensive article on this still poorly recognized condition. We will cover the precise definition of PAMM, its pathophysiological mechanisms, identified risk factors, characteristic symptoms, modern diagnostic methods — particularly OCT and OCT angiography — as well as current management and long-term visual prognosis.

OCT angiography (or OCT-A) is a recent imaging technique that allows visualization of blood circulation in the retina and choroid without dye injection. It complements standard macular OCT and fluorescein angiography. Dr Julien Gozlan, ophthalmic surgeon in Paris 16, explains the principle, indications, and limitations of OCT angiography.

Indocyanine green angiography (ICG) is an imaging examination that highlights the choroidal circulation, located beneath the retina. Complementary to fluorescein angiography and macular OCT, indocyanine green angiography aids in diagnosing choroidal conditions and guides their treatment.

Fluorescein angiography is a retinal imaging examination that allows observation of blood circulation and identification of leaks, hemorrhages, or ischemia. Performed in the office, this examination helps establish a precise diagnosis and guide the treatment of macular conditions such as AMD, or retinal vascular disorders such as CRVO. Dr Julien Gozlan explains its principle, indications, procedure, and risks.

OCT (optical coherence tomography) is a retinal imaging exam that has become essential in ophthalmology. It allows highly precise analysis of the macula – the central area of the retina responsible for fine vision. Dr Julien Gozlan, ophthalmic surgeon in Paris 16, explains what macular OCT involves, when it is indicated, and how the examination is performed.
