The daily (400 mg/day) and cumulative dose (100 g) combined with the length of therapy is associated with the toxicity. Toxic effects may also be observed at lower maintenance doses, as observed in this patient. This case indicates that multi-organ toxicity due to amiodarone may develop even with short-term use and a low maintenance dose. Having been off the medication for two months, it is expected that the deposition pattern will diminish, as is the case for the vast majority of patients.","PeriodicalId":39864,"journal":{"name":"Asian Journal of Ophthalmology","volume":"17 1","pages":"170-172"},"PeriodicalIF":0.0,"publicationDate":"2020-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44791413","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}

Visual acuity was initially 20/20 upon resolution of the hyphema but worsened to 20/40 a year after, presumably due to a developing cataract. Periodic dilated fundus examinations revealed no hypotony maculopathy or choroidal effusions. Prior to phacoemulsification, ultrasound biomicroscopy (UBM) revealed 360 degrees of mild peripheral choroidal effusions. During phacoemulsification, after intraocular lens insertion, direct gonioscopy revealed a supero-nasal cyclodialysis cleft (2 clock hours) and this was repaired intraoperatively with direct cyclopexy through a partial thickness scleral flap. Postoperatively, the vision improved to 20/20 without correction and the IOP normalized to 16 to 18 mmHg. \u0000Conclusion: Chronic hypotony post-trauma may be asymptomatic and the cause may not be clinically evident and may be detected by UBM (choroidal effusion).

Subgroup analyses between low myopia (refraction -3.00 D to -6.00 D), and high myopia (> -6.00 D to -8.00 D) and pathologic myopia (more than -8.00 D) were done. Macular and RNFL thickness were measured by a SD-OCT and axial length (AL) with non-contact biometry. \u0000Results: Of 156 eyes, 88/156 (56%) had low-moderate myopia, 68/156 (44%) had high-pathologic myopia. There were 67/156 (43%) male and 89/156 (57%) female subjects. Mean central foveal subfield thickness measurements were 264 ± 24 μm for low myopia, 258 ± 17 μm for moderate myopia, 253 ± 25 μm for high myopia, and 218 ± 48 μm for pathologic myopia. Mean RNFL thickness measurements were 105.62 ± 3.89 μmfor low myopia, 97.6 ± 2.45 μm for moderate myopia, 85.9 ± 3.87 μm for high myopia, and 75.14 ± 3.89 μm for pathologic myopia.
