PURPOSE: The aim of this report was to describe multimodal ocular imaging findings in a patient who presented with a ruptured retinal arterial macroaneurysm (RAM) associated with toxoplasmic Kyrieleis arteriolitis. METHODS: We report the case of a 64-year-old man with a history of systemic hypertension and dense amblyopia of the left eye who presented with decreased vision and new floaters in the left eye. Color fundus photography, spectral-domain optical coherence tomography, fluorescein angiography, and indocyanine green angiography were used as diagnostic imaging tools...

REVIEW
Tedi Begaj, Shlomit Schaal
Unprotected and prolonged exposure to ultraviolet (UV) light from sunlight, lasers, and arc welding leads to outer retinal damage. The photoreceptors and retinal pigment epithelium located in the posterior pole are particularly susceptible to this radiation. Classically known as solar retinopathy, this disorder frequently affects young individuals who have clear lenses and a propensity toward observing solar eclipses. Various imaging techniques aid the clinician in diagnosis, even if patients cannot recall an exposure event...

PURPOSE: To describe the contribution of multimodal imaging in the various stages of Stargardt disease (STGD). PATIENTS AND METHODS: We retrospectively reviewed 46 eyes of 23 STGD patients with identified ABCA4 mutations. All patients underwent a complete ophthalmic examination, spectral-domain optical coherence tomography (SD-OCT), fundus autofluorescence (FAF), fluorescein angiography (FA) and Indocyanine green angiography (ICGA). RESULTS: The mean age of patients was 25...

Purpose: Recent progress in retinal laser therapy has centered upon using thermal stress below damage threshold or selective destruction of targeted tissue layers as a stimulus for retinal repair. Temporal modulation, including micropulse, is thought to increase the selectivity of laser treatment, but has not been carefully analyzed. We measure and model the tissue response to continuous-wave (CW) and micropulse laser to evaluate the advantages and drawbacks of temporal modulation. Methods: Thresholds of ophthalmoscopic visibility, which indicates damage to photoreceptors, and fluorescein angiography (FA), indicating damage to retinal pigment epithelium (RPE), were measured with 577-nm laser in rabbits for duty cycles ranging from 3% to 100% (CW) and pulse envelopes of 20 and 200 ms...

BACKGROUND: PAX6 is a master gene of ocular development and postnatal ocular equilibrium. Congenital aniridia is the hallmark of PAX6 gene haploinsufficiency (Chr. 11 p. 13), but PAX6-associated aniridia is a profound, progressive pan-ocular developmental disorder often leading to blindness. Limbal stem cell insufficiency and corneal findings in PAX6 syndrome: There is congenital visual impairment with advancing loss of vision mainly due to secondary glaucoma and to corneal blindness caused by limbal stem cell insufficiency (LSCI)...

We describe a case of a 65-year old man diagnosed with retinal vasoproliferative tumour secondary to posterior uveitis. The fluorescein angiography shows an interesting meteor-like leak emanating from the tumour and rising towards the superior retina in the later frames of the angiogram. Pictorially, we call it the "Retinal Meteor" and also describe the possible mechanism for this pattern of leakage.

The use of imaging for age-related macular degeneration (AMD) depends on how it benefits clinical management and on reimbursement. The latter should relate to the former. This review assesses how different forms of AMD can be imaged and what information this provides. For nonneovascular AMD high-resolution optical coherence tomography (OCT), autofluorescence, and near infrared imaging can identify the type of drusen, such as reticular pseudodrusen, which influences prognosis, and the amount of atrophy, for which phase 3 trials are underway...

PURPOSE: To investigate the influence of hormone therapy with tamoxifen or estrogens on morphological changes in macular telangiectasia (MacTel) type 2 patients as revealed clinically in multiple imaging modalities. METHODS: Patients with a history of tamoxifen or estrogen use were selected from the cohort of the MacTel Study. A race-, age- and best-corrected visual acuity-matched group of MacTel participants not under hormone therapy served as the comparison group...

BACKGROUND AND OBJECTIVE: New imaging methods provide novel insights into the pathogenesis of acute posterior multifocal placoid pigment epitheliopathy (APMPPE). PATIENTS AND METHODS: Four patients (eight eyes) in acute, subacute, and late phases of the disease were analyzed with multi-modal imaging methods including optical coherence tomography angiography (OCTA), structural OCT, fundus photography, and fundus autofluorescence. One patient was observed during the entire disease course...

PURPOSE: To investigate vascular perfusion and foveal avascular zone area in the superficial capillary plexus (SCP) and deep capillary plexus (DCP) after intravitreal aflibercept therapy in central retinal vein occlusion eyes and their association with best-corrected visual acuity. METHODS: Thirty-five subjects with central retinal vein occlusion and macular edema were evaluated. After macular edema resolution following intravitreal aflibercept, subjects underwent optical coherence tomography angiography to measure SCP and DCP perfusion and the foveal avascular zone within a 3 × 3-mm area...

PURPOSE: To compare the detection rate of choroidal neovascularization (CNV) in treatment-naive neovascular age-related macular degeneration by swept source optical coherence tomography angiography (SS-OCTA, Topcon's DRI Triton) working at 1,050 nm wavelength versus fluorescence angiography. METHODS: Cross-sectional analysis of 156 eyes (107 neovascular age-related macular degeneration and 49 dry AMD) in 98 patients, previously diagnosed by multimodal imaging using fluorescein (FA) and indocyanine green angiography (Heidelberg's Spectralis) in a tertiary retina center, evaluated by SS-OCTA 4...

OCT angiography provides a combination of vascular and structural information. In contrast to conventional fluorescein angiography, there is no need for dye injection to give an image of choroidal neovascularisation. Although there is currently no classification of OCT angiography, different neovascular patterns can be observed, with criteria for activity. In the future, OCT angiography may help us to understand pathophysiological mechanisms and to develop therapeutic strategies.

PURPOSE: Optical coherence tomography angiography (OCTA) can visualize the vascular status of the choriocapillaris noninvasively and separately from the other vascular beds. We describe focal ischemia in the choriocapillaris and reperfusion of the area in hypertensive choroidopathy using en-face OCTA. CASE: A 32-year-old woman diagnosed with pregnancy-induced hypertension presented with acute anorthopia in the right eye after delivery via Caesarian section. Fundus examination showed an Elschnig's spot and serous retinal detachment (SRD) in the inferior perifoveal region...

PURPOSE: To evaluate the efficacy of intravitreal bevacizumab in the treatment of choroidal neovascularization (CNV) secondary to angioid streaks. METHODS: We conducted a prospective study in the ophthalmology department of Hassan II university hospital in Fez, including 12 eyes of 7 patients with CNV associated with angioid streaks. We injected 8 eyes with bevacizumab 1.25mg; best corrected visual acuity (BCVA), fundus examination, fluorescein angiography and optical coherence tomography were performed and analyzed for all patients before and after treatment...

Susac Syndrome is a rare entity, characterized by a triad of subacute encephalopathy, retinal artery occlusion and sensorineural hearing loss. It is more common in women and the age of onset fluctuates between 9-58 years of age. The pathogenesis is presented as microangiopathic changes at the cerebral, retinal and cochlear levels associated with an autoimmune mechanism. We present the case of a 31-year-old woman who started with a diffuse headache, puerile behavior, bradylalia and somnolence. As the disease progressed, she had auditory deficit and arterial obstruction of the right temporal retinal branch in retinal fluorescein angiography...

IMPORTANCE: Retinal artery occlusion (RAO) is a medical emergency associated with a high risk of cerebral vascular accident and other cardiovascular events. Among patients with non-arteritic RAO, a retinal embolus is observed in approximately 40% of cases. Fundus examination and retinography are not reliable to predict the nature of the emboli. OBSERVATIONS: We report three consecutive cases of central and branch RAO that were investigated with fundus autofluorescence, fluorescein angiography and color retinal photographs...
