RESUMO
OBJECTIVE: To study the prevalence of intraocular tumours detected by screening ultrasonography in eyes with opaque media. METHODS: Retrospective review of B-scan ultrasonography in eyes with opaque media and diagnosis of blindness or phthisis between January 1, 1994, and December 31, 2013. Ultrasounds for diagnostic purposes in acute endophthalmitis, retinal detachment, or vitreous hemorrhage were excluded. RESULTS: There were 119 blind eyes with opaque media examined with B-scan ultrasonography. Mean patient age was 59 years, with visual acuity of hand motions or worse in 89 eyes (74.8%), elevated intraocular pressure in 23 eyes (19.3%), and pain in 30 eyes (25.4%). Follow-up was ≥1 year in 69 eyes (58%) with a mean 64 months (median, 56 months; range, 12-129 months). Of these 69 eyes, ultrasound frequency was more often than annual in 2 eyes (2.9%), annual in 2 eyes (2.9%), every 13-60 months in 43 eyes (62%), every 61-120 months in 19 eyes (27.5%), and less often than every 120 months in 3 eyes (4.3%). Sixteen eyes with opaque media only received ultrasound at presentation, and 6 eyes had screening ultrasonography only prior to evisceration or enucleation. No intraocular tumours were detected in any eye during the study period. CONCLUSIONS: In this series, no intraocular tumours were detected by screening ultrasonography in eyes with opaque media. Larger studies with long-term follow-up are required to determine the utility and cost-effectiveness of serial ultrasonography monitoring. Ultrasound may have its highest utility in the setting of initial evaluation, clinical change, and preoperative work-up to avoid evisceration in the setting of occult malignancy.

PURPOSE: To describe the features of choroidal tumors on infrared (IR) imaging and to determine the diagnostic sensitivity and specificity of intratumoral choroidal vascular loops on IR imaging for circumscribed choroidal hemangioma (CCH). METHODS: Infrared and indocyanine green images of CCH, choroidal metastases, and choroidal melanomas were reviewed. The main outcome measure was the presence of intratumoral choroidal vascular loops and tufts on IR images. The secondary outcome measure was the presence of peritumoral vascular expansion on indocyanine green images. RESULTS: Intratumoral CCH vessels appear as dark beaded spaces on IR imaging; 95.5% of CCH had vascular loops compared with the controls of 65% in choroidal melanomas and 64% in choroidal metastases. The sensitivity of intratumoral vessels on IR for CCH was 95.4%. Subanalysis of six patients with CCH showed the presence of peritumoral vascular expansion on indocyanine green images. CONCLUSION: Infrared imaging delineates intratumoral vessels in choroidal tumors appearing as dark beaded loops and tufts. Vascular loops on IR imaging showed a high diagnostic sensitivity for CCH. The absence of these loops on IR can help rule out the diagnosis of CCH. Peritumoral vascular expansion on indocyanine green is an additional diagnostic tool that is helpful in the diagnosis of CCH.

Hematopoietic stem cell transplantation is important in the management of several lymphoproliferative and bone marrow disorders. Graft-versus-host disease (GVHD) involves inflammatory manifestations that arise after transplant and can affect many organs. Ocular manifestations of GVHD are common, and eye care providers must understand this disease entity. The ocular surface is most commonly involved, but GVHD can affect all parts of the eye. Ocular GVHD can be relapsing and remitting, can decrease quality of life, and can be challenging to diagnose and adequately treat. The diagnostic criteria for and grading of ocular GVHD continue to evolve. This review aims to summarize current definitions, clinical findings, diagnostic criteria, and management of ocular GVHD. The care of patients with ocular GVHD requires a multidisciplinary approach.

PURPOSE: The purpose of this case report was to demonstrate evidence of indocyanine green angiography leakage consistent with choroiditis in a patient with scleroderma. METHODS: In this case report, the patient underwent a variety of tests and examinations, including systemic evaluation, full ocular examination, skin biopsy, indocyanine green, and fluorescein angiography testing. A 52-year-old man had blurred vision centrally in both eyes. Vision was 20/25 and 20/20. Posterior examination showed cotton-wool spots in both eyes. The patient met European League against Rheumatism (EULAR) criteria for scleroderma. RESULTS: Fluorescein angiography confirmed the presence of leakage from the retinal vessels. More importantly, indocyanine green angiography revealed choroidal vessel leakage in both eyes. This provided evidence of choroiditis before vessel obliteration. Previous studies have shown evidence of choriocapillaris obliteration. Choroidal vessel leakage, however, has not been reported in patients with scleroderma. CONCLUSION: The results of this case demonstrate the usefulness of indocyanine green angiography in detecting the presence of choroiditis in scleroderma.

BACKGROUND: Sarcoid-like reactions have been reported and confirmed by histopathology in patients with malignant disease. This series demonstrates the complex relationship of malignancy and sarcoidosis as pertaining to the eye, which, to the best of our knowledge, has not been previously reported in the literature. METHODS: Retrospective case study of five patients with sarcoid-like reactions. Patients 1 to 4 represent patients with ocular sarcoid-like reaction and systemic malignant disease. Patient 5 had ocular malignancy and systemic sarcoid-like reaction; workup revealed renal cell cancer. For each patient, other etiologies of nonnecrotizing granulomatous inflammation were excluded. RESULTS: Sarcoid-like reactions have been described in the literature when nonnecrotizing granulomas occur in association with malignancy and in the absence of multiorgan involvement as seen with systemic sarcoid. In our series, sarcoid-like reactions involved the vitreous in three patients, retina in one patient, and the choroid and lung in one patient. Sarcoid-like reaction preceded the diagnosis of malignancy in two patients, was found concomitantly with malignancy in one patient, and followed malignancy in two patients. Two patients had hematologic malignancy, one patient had endometrial carcinoma, one had renal cell carcinoma, and one patient had both renal cell carcinoma and uveal melanoma. Four patients had findings of nonnecrotizing granulomas confirmed by histopathology. CONCLUSION: Sarcoid-like reactions can occur in the eye, and ocular malignancies may incite sarcoid-like reaction. Ocular sarcoid-like reactions have paraneoplastic features in that they can occur at a site distant from malignancy and may precede, occur simultaneously with, or follow malignancy.

The purpose of this article is to demonstrate the utility of the large spot size (LSS) setting using a binocular laser indirect delivery system for peripheral ablation in children. One patient with bilateral retinopathy of prematurity received photocoagulation with standard spot size burns placed adjacently to LSS burns. Using a pixel analysis program called Image J on the Retcam picture, the areas of each retinal spot size were determined in units of pixels, giving a standard spot range of 805 to 1294 pixels and LSS range of 1699 to 2311 pixels. Additionally, fluence was calculated using theoretical retinal areas produced by each spot size: the standard spot setting was 462 mJ/mm2 and the LSS setting was 104 mJ/mm2. For eyes with retinopathy of prematurity, our study shows that LSS laser indirect delivery halves the number of spots required for treatment and reduces fluence by almost one-quarter, producing more uniform spots.

BACKGROUND: Low-dose aspirin reduces cardiovascular risk; however, monitoring over-the-counter medication use relies on the time-consuming and costly manual review of medical records. Our objective is to validate natural language processing (NLP) of the electronic medical record (EMR) for extracting medication exposure and contraindication information. METHODS: The text of EMRs for 499 patients with type 2 diabetes was searched using NLP for evidence of aspirin use and its contraindications. The results were compared to a standardised manual records review. RESULTS: Of the 499 patients, 351 (70%) were using aspirin and 148 (30%) were not, according to manual review. NLP correctly identified 346 of the 351 aspirin-positive and 134 of the 148 aspirin-negative patients, indicating a sensitivity of 99% (95% CI 97-100) and specificity of 91% (95% CI 88-97). Of the 148 aspirin-negative patients, 66 (45%) had contraindications and 82 (55%) did not, according to manual review. NLP search for contraindications correctly identified 61 of the 66 patients with contraindications and 58 of the 82 patients without, yielding a sensitivity of 92% (95% CI 84-97) and a specificity of 71% (95% CI 60-80). CONCLUSIONS: NLP of the EMR is accurate in ascertaining documented aspirin use and could potentially be used for epidemiological research as a source of cardiovascular risk factor information.
