Observation of changes after peripheral retinal injury by cosmetic laser, using wide-field scanning laser ophthalmoscope: A case report

We report a case of peripheral retinal injury caused by a 1064-nm Nd:YAG: neodymium-doped yttrium aluminum garnet. Patient concerns: A 27-year-old Asian woman was admitted with scotoma symptoms in her right eye. The patient was a skin care technician. Three days before admission, a laser beam had struck her eye while she was preparing for a laser procedure. Diagnosis: During fundus examination, a subretinal hemorrhage with disc diameter (DD) of 4.0 and a preretinal hemorrhage of 2.5 DD in its center were found in the 2 o’clock position of the peripheral retina in the right eye. Interventions: We monitored the injury for> 6 months, first using fluorescein angiography, then wide-field scanning laser ophthalmoscopy and optical coherence tomography. Oral steroids and vitamins were administered. Outcomes: During the 6-month follow-up period, blood from the initial sub- and preretinal hemorrhage, as well as vitreous hemorrhage, were all absorbed. Retinal detachment was not observed as scar formation and adhesions had occurred. No interventions were considered necessary. Lessons: When treating a patient who has experienced laser eye injury, the possibility of peripheral retinal injury should be considered. Peripheral retinal injury caused by 1064-nm Nd:YAG: neodymium-doped yttrium aluminum garnet has a relatively good prognosis, suggesting that it will not progress to retinal detachment.

We report the case of a 22 year-old male with a clinical picture of 4 months onset of headaches, deafness, and a decrease of vision in the left eye. His mother mentioned he also had changes in behaviour and mood. The magnetic resonance scan of the brain showed multiple hyper-intense lesions in the knee of the corpus callosum. The hearing test reported a neurosensory deafness. In the ophthalmoscopy, a retinal infarction was observed in the nerve fibre layer in the left eye, which was confirmed using optical coherence tomography. The fluorescein angiography showed multiple foci of hyperfluorescence of the arteriole walls, ar...

Abstract BACKGROUND/IMS: To compare the retinal vessel diameter measurements obtained from the swept-source optical coherence tomography angiography (OCTA; Plex Elite 9000, Carl Zeiss Meditec, USA) and adaptive optics ophthalmoscope (AOO; RTX1, Imagine Eyes, France). METHODS: Fifteen healthy subjects, 67% women, mean age (SD) 30.87 (6.19) years, were imaged using OCTA and AOO by a single experienced operator on the same day. Each eye was scanned using two OCTA protocols (3×3 mm2 and 9×9 mm2) and two to five AOO scans (1.2×1.2 mm2). The OCTA and AOO scans were scaled to t...

This article reviews emerging technologies in retinal imaging, including their scientific background, clinical implications and future directions. Recent findings Fluorescence lifetime imaging ophthalmoscopy is a technology that will reveal biochemical and metabolic changes of the retina at the cellular level. Optical coherence tomography is evolving exponentially toward higher resolution, faster speed, increased portability and more cost effective. Adaptive optics scanning laser ophthalmoscopy fluorescein angiography will provide unprecedented detail of the retinal vasculature down to the level of capillaries, enabling...

ConclusionThe clinical presentation and genetic studies confirmed a diagnosis of Cockayne syndrome in both sisters caused by compound heterozygous mutations in theERCC8 gene on chromosome 10. Multimodal ocular imaging and systemic findings revealed wide phenotypic variability between the affected siblings.

Authors: Foote KG, Roorda A, Duncan JL Abstract Choroideremia (CHM) is associated with progressive degeneration of the retinal pigment epithelium (RPE), choriocapillaris (CC), and photoreceptors. As animal models of CHM are lacking, most information about cell survival has come from imaging affected patients. This chapter discusses a combination of imaging techniques, including fundus-guided microperimetry, confocal and non-confocal adaptive optics scanning laser ophthalmoscopy (AOSLO), fundus autofluorescence (FAF), and swept-source optical coherence tomography angiography (SS-OCTA) to analyze macular sensitivity,...

This study used a murine model to test the hypothesis that intravitreal injection of human CD34 + stem cells harvested from bone marrow (BMSCs) can have protective effects in eyes with diabetic retinopathy. Streptozotocin-induced diabetic mice (C57BL/6J) were used as a model for diabetic retinopathy. Subcutaneous implantation of Alzet pump, loaded with Tacrolimus and Rapamycin, 5 days prior to intravitreal injection provided continuous systemic immunosuppression for the study duration to avoid rejection of human cells. Human CD34 + BMSCs were harvested from the mononuclear cell fraction of bone marrow from a health...

We present a case series in which 5 eyes of 3 patients with Eales disease were evaluated by using retinal fluorescein angiography with 30 º, 50º, and 150º lenses in a laser-scanning ophthalmoscope. These cases highlight the usefulness of wide-field fluorescein angiography in the diagnosis and follow-up of peripheral ischemic retinal areas in Eales disease, which enables better follow-up than possible with conventional fluorescein a ngiography images.RESUMO A angiografia de campo amplo permite avaliar áreas periféricas com melhor qualidade e proporciona maior foco profundo, melhorando a imagem d...

Purpose: To investigate the difference in choroidal hyperpermeability (CH) assessed using digital fundus camera (DFC) and scanning laser ophthalmoscope (SLO) and its effect on photodynamic therapy (PDT) outcomes in chronic central serous chorioretinopathy. Methods: Midphase indocyanine green angiography (ICGA) images were acquired using both DFC and SLO in 38 consecutive eyes with chronic central serous chorioretinopathy in this retrospective study. Scanning laser ophthalmoscope-ICGA was taken immediately after DFC-ICGA. Photodynamic therapy was applied to the area of CH associated with subretinal fluid (CH-SRF). The ...

Polypoidal choroidal vasculopathy (PCV) is a clinical syndrome with unique indocyanine green angiography (ICGA) features of typical nodular hyperfluorescence that was initially thought to be an intrachoroidal vascular abnormality. Confocal scanning laser ophthalmoscopic ICGA has shown that the associated branching vascular network (BVN) is similar to occult choroidal neovascularization angiographically. The advent of spectral-domain optical coherence tomography (OCT) has shown that the BVN is indistinguishable from type 1 choroidal neovascularization (CNV), occupying the space between the retinal pigment epithelium and the...
