چکیده

Non‐dilating pupils due to anterior segment inflammation in uveitis commonly interfere with a proper fundus examination. Ultrawide field fundus imaging (UWFI, Optos 200 TxTM; Optos PLC., Dunfermline, Scotland, United Kingdom) uses a confocal scanning laser ophthalmoscope. The aim of this manuscript is to describe the utility of UWFI in cases of uveitis with non‐ dilating pupils. Consent was taken from all the patients and the declaration of Helsinki was followed during patient care. A 32‐year‐old woman (Case 1) had smal l pupils in both eyes. She had 5/60 vision in both eyes with bilateral early posterior subcapsular cataracts [Figure 1a], and cystoid macular edema. The UWFI enabled us to document the associated vitritis [Figure 1b]. No other retinochoroidal lesion or vasculitis was seen. Thus, a diagnosis of intermediate uveitis was made. A 43‐year‐old woman (Case 2) with acquired immunodeficiency syndrome and a CD4 count of 33 presented with bilateral perception of light and inaccurate projection of rays. Both eyes had posterior synechiae, right eye had an early cataract [Figure 2a] and left eye had a mature cataract. Further, UWFI Ultrawide Field Imaging in Uveitic Non‐dilating Pupils

Use of Malyugin Pupil Expansion Ring in Femtosecond Laser-assisted Cataract Surgery

Non dilating narrow pupils are a challenge for cataract surgeons. The Malyugin pupil expansion device (Microsurgical Technology) has several advantages over traditional iris retractor hooks or other pupil dilating devices [1]. This is a disposable, square shaped implant, made of polypropylene with four circular scrolls that engage the pupillary margin at equidistant points providing a balanced ...

Pupil-mimicry conditions trust in partners: moderation by oxytocin and group membership

Across species, oxytocin, an evolutionarily ancient neuropeptide, facilitates social communication by attuning individuals to conspecifics' social signals, fostering trust and bonding. The eyes have an important signalling function; and humans use their salient and communicative eyes to intentionally and unintentionally send social signals to others, by contracting the muscles around their eyes...

Pupil Mimicry Correlates With Trust in In-Group Partners With Dilating Pupils.

During close interactions with fellow group members, humans look into one another's eyes, follow gaze, and quickly grasp emotion signals. The eye-catching morphology of human eyes, with unique eye whites, draws attention to the middle part, to the pupils, and their autonomic changes, which signal arousal, cognitive load, and interest (including social interest). Here, we examined whether and ho...

Quality and learning curve of handheld versus stand-alone non-mydriatic cameras

PURPOSE Nowadays, complex digital imaging systems allow detailed retinal imaging without dilating patients' pupils. These so-called non-mydriatic cameras have advantages in common circumstances (eg, for screening or emergency purposes) but present limitations in terms of image quality and field of view. We compare the usefulness of two non-mydriatic camera systems (ie, a handheld versus a stand...
