Portable color retinography findings in COVID-19 patients admitted to the ward.

Retinal lesions, including cotton-wool exudates, microbleeds, vascular occlusions and vasculitis, occur in a minority of Coronavirus Disease-19 (COVID-19) patients. Retinal assessments using retinography can help document these lesions. The objective of this work was to identify retinal changes in patients admitted to the ward with a positive Real Time Quantitative Polymerase Chain Reaction (RT-qPCR) exam for COVID-19. A cross-sectional, observational study was carried out of patients with mild and moderate symptoms admitted to the Hospital de Base in São José do Rio Preto. The Eyer® portable retinal camera (Phelcom® Technologies) was used to evaluate 30 male and 21 female patients. The ages ranged from 21 to 83 years (mean: 47 years). Systemic arterial hypertension was identified in 21 (41.2 %) and diabetes mellitus in 12 (23.5 %) patients. Six (11.7 %) reported worsening visual acuity, however, none of these patients had ocular findings to justify this complaint. Ten patients (19.6 %) had intraretinal hemorrhages; one (1.9 %) had cotton-wool exudates and seven (13.7 %) had dilations of veins. Thirteen patients (25.4 %) had vascular tortuosity and six (11.7 %) had pathological arteriovenous crossings. Portable retinography is useful to evaluate patients admitted to isolation wards due to COVID-19. It is important to remember that some of the patients investigated had comorbidities like diabetic maculopathy and systemic arterial hypertension. Hence, some care should be taken in attributing these observations uniquely to COVID-19 infection.

[Ocular toxicity caused by tamoxifen: case report]. / Toxicidade ocular causada pelo tamoxifeno: relato de caso.

To report tamoxifen ocular toxicity. The best visual acuity was measured in both eyes with Snellen chart, slit-lamp examination of anterior segment, refraction, dilated fundus examination, fluorescein angiography and retinography in a 63-year-old patient, female, white, using tamoxifen 20 mg/day for 4 years, with 20/70 and 20/40 corrected visual acuity. The anterior segment examination showed corneal linear subepithelial opacity inferior to the visual axis and nuclear and posterior cortical cataract (1+/4) in both eyes. Fundus examination showed alteration of macular color in both eyes. Fluorescein angiography presented hyperfluorescence in the macular area at an early phase (window defect). Report of keratopathy and maculopathy caused by tamoxifen.

[Ocular toxicity caused by chloroquine: case report]. / Toxicidade ocular causada pela cloroquina: relato de caso.

To report a case of ocular toxicity due to chloroquine. The best visual acuity was measured in both eyes with the Snellen chart. Slit-lamp examination of anterior segment, refraction, dilated fundus examination, fluorescein angiography and retinography was done in a 53-year-old patient, female, with rheumatoid arthritis. She had used chloroquine during 6 years and had stopped for 1 year when she came to our service. She had best corrected visual acuity of 20/200 and 20/40. Slit-lamp examination showed intraocular lens in right eye and nuclear cataract (1+/4) in the other, and bilateral corneal subepithelial opacity inferior to the visual axis. Fundus examination showed macular area with retinal pigment epithelium atrophy. Fluorescein angiography showed a bull's eye maculopathy. Report of a typical keratopathy and maculopathy caused by chloroquine.

Toxicidade ocular causada pelo tamoxifeno: relato de caso / Ocular toxicity caused by tamoxifen: case report

O objetivo desse trabalho é relatar um caso de toxicidade ocular pelo tamoxifeno. Para isso, aferiu-se a melhor acuidade visual corrigida de ambos os olhos em tabela de Snellen. Foram realizados biomicroscopia do segmento anterior, refração, oftalmoscopia, angiofluoresceinografia e retinografia numa paciente de 63 anos, sexo feminino, cor branca, em uso de tamoxifeno 20 mg/dia há 4 anos, com acuidade visual corrigida de 20/70 e 20/40. A biomicroscopia do segmento anterior apresentava ceratopatia verticilata e catarata nuclear e cortical posterior de 1+/4 em ambos os olhos. A oftalmoscopia, foi verificado alteração do brilho macular de ambos os olhos. E a angiofluoresceinografia mostrou hiperfluorescência na área macular em fase precoce (defeito em janela). Relata-se um caso de ceratopatia e maculopatia causadas pelo tamoxifeno.

Toxicidade ocular causada pela cloroquina: relato de caso / Ocular toxicity caused by chloroquine: case report

Relatar um caso de toxicidade ocular causada pela cloroquina. Aferiu-se a acuidade visual de ambos os olhos em tabela de Snellen. Foram realizados biomicroscopia do segmento anterior, refração, oftalmoscopia, angiofluoresceinografia e retinografia numa paciente de 53 anos, sexo feminino, portadora de artrite reumatóide. Fez uso de cloroquina por 6 anos e havia parado há um ano, quando veio ao nosso serviço. Apresentava acuidade visual corrigida de 20/200 e 20/40. A biomicroscopia do segmento anterior apresentava lente intra-ocular no olho direito e catarata nuclear 1+/4+ no olho esquerdo, com opacidade corneana subepitelial inferior ao eixo visual em ambos os olhos. A oftalmoscopia, apresentava mácula com aspecto de tacho batido (atrofia do epitélio pigmentar da retina). A angiofluoresceinografia mostrou maculopatia com aspecto de olho de boi. Relata-se um caso típico de ceratopatia e maculopatia causados pela cloroquina.
