[en] Out of 124 CT (computerized tomography) examinations made by the Ophtalmological Department of the Regional Hospital in Usti nad Labem during the last threee years, in 10 cases orbits with the presence of intraocular foreign bodies were examined. Experience is reported assembled during the mentioned applications of CT in the diagnosis of intraocular foreign bodies. Advantages but also certain limitations are discussed of the localization of foreign bodies using CT. In two out of 10 cases the foreign body was located by CT incorrectly. In the remaning eight cases the CT examination was a great asset and contributed greatly to successful operation (50% of patients with vision of 6/6). (author). 13 figs., 1 tab., 10 refs

[en] Description of a 4 year old girl with acute lymphatic leukeamia in total bone marrow remission, with infiltrations in iris and uveitis, complicated by hypopisn and raised intraocular pressure. A diagnostic paracentesis of the anterior chamber was performed with a cytologic diagnosis established. With radiation of the anterior segment of the eye the leukaemic infiltration of the iris, hypopion and glaucoma cleared. It appears that a barrier perhaps exists which does not allow for full penetration of the iris by cytostatics so that residual leukaemic cells remain after initial therapy

[en] Annual clinical eye examinations have been performed on the CRHL Segment III beagles since inception of the study. It is now possible to present the estimated cumulative incidence probabilities for selected ocular lesions based on the complete set of data. Although there appears to be relatively little difference between most experimental groups, there is some evidence that ocular lesions may be more frequent in dogs irradiated at 28 or 55 days postcoitus (dpc) or 2 days postpartum

[en] Macular telangiectasia type 2 (Mac Tel 2) is a bilateral disease of unknown cause with characteristic changes of the retinal vasculature. To the best of our knowledge, we could not find any reported cases of Mac Tel 2 with retinal arterial macroaneurysm (RAM). Our aim is to report a case of Mac Tel 2 with RAM.

[en] The purpose of this m anuscript is to present the use of CT in the evaluation of 42 cases of orbital lesions studied at the National Institute of Cancer in an one year and half period. Correlation with clinical and pathological data was performed and the results compared with those of the literature. Four cases of rare lesions are shown: alveolar soft tissue sarcoma, giant cell tumor and hematogenic metastatic deposits of a clear cell sarcoma and epidermoid carcinoma. The value of CT in the evaluation of all orbital masses is emphasized. (author)

[en] Objective: Eye-tracking devices have become widely used as clinical assessment tools in a variety of applied-scientific fields to measure saccadic eye movements. With the emergence of multiple static and dynamic devices, the concurrent need for algorithm development and validation is paramount. Approach: This review assesses the prevalence of current saccade detection algorithms, their associated validation methodologies and the suitability of their application. Medline, Embase, PsychInfo, Scopus, IEEEXplore and ACM Digital Library databases were searched. Two independent reviewers and an adjudicator screened articles describing the detection of saccades from raw infrared/video-based eye-tracker data. Main results: Thirteen articles were screened and met the inclusion criteria. Overall, the majority of reviewed saccadic detection algorithms used simple velocity-based classifications with static eye-tracking systems. Studies demonstrated validity but are limited by the static nature of testing. Heterogeneity in system design, proprietary and bespoke algorithmic methods used, processing strategies, and outcome reporting is evident. Significance: This paper suggests the use of a more standardised methodology to facilitate experimental validity and improve comparison of results across studies. (topical review)
