We report a 50-year-old male with PDR whose pattern scanning laser (Pascal®) procedure was complicated by an accidental foveal burn. On initial evaluation, the best-corrected visual acuity of the affected eye was 20/40. Fundoscopy revealed multiple laser burns in the macula, one of which crossed the fovea. The optical coherence tomography (OCT) showed an inadvertent burn at the foveal region and multiple parafoveal laser spots with the disrupted corresponding external limiting membrane (ELM), ellipsoid (EZ), and interdigitation zones. The patient underwent serial follow-up examinations. Six months after laser therapy, vision significantly recovered and improved to 20/20 in the affected eye. The results of follow-up OCT imaging showed that the ELM defect had fully recovered and the EZ defect had become smaller, as an unexpected and rare outcome. As a rare and interesting condition, laser burns around the foveal region seem to have the chance of retinal recovery over time. However, in most of the similar conditions, these accidental foveal laser burns lead to permanent severe visual impairment. Therefore, well-trained physicians must do retinal laser procedures.","PeriodicalId":437914,"journal":{"name":"Latin American Journal of Ophthalmology","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129614354","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several retinal and choroidal diseases have been characterized using this index. However, no study has established the association of CVI with myopic traction maculopathy (MTM). This study aimed to investigate the association of CVI with different stages of surgically resolved MTM. We performed a consecutive, interventional, one-surgeon, and case-series study of 6 eyes of six patients enrolled between April 2017 and June 2022. One normal emmetropic eye (emmetropic control), one healthy myopic vision (healthy myopic control), and four surgically resolved myopic eyes at different stages of MTM (surgery group) were evaluated using OCT. The OCT images were binarized, and the total choroidal area (TCA, mm2), vascular luminal area (LA, mm2), and choroidal stromal area (SCA, mm2) were quantified using ImageJ software. The CVI (%) was calculated as the ratio of LA to TCA. The primary outcome measure was the association of the CVI with the best-corrected visual acuity in either of the study eyes. The baseline patient characteristics were similar (P > 0.05), except for visual acuity, which was better in the control eyes (P < 0.05). The CVI was 68.2% in the emmetropic control eye and 61.5% in the healthy myopic vision, whereas the mean CVI in the surgical group was 47.8% (40.9–53.3, min to max) (P = 0.07).","PeriodicalId":437914,"journal":{"name":"Latin American Journal of Ophthalmology","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128885722","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
