Post-mortem iris recognition (PMIR) is a recently developed area of expertise falling into the broader category of biometric methods utilizing human iris features for the purpose of automatic or semi-automatic establishing or confirming one's identity. Yet, contrary to traditional iris recognition applied to living individuals, post-mortem biometrics presents forensic experts and scientists with challenges that have previously been unknown and require novel approaches and development of new skills. This paper summarizes the current state of the art of research in this area, both with respect to studies exploring the feasibility of iris recognition in a forensic setting, as well as the challenges still pervasive in the scientific community and potential ways to overcome them.

Normally, these tend to revert when one stops fixating on a near object. Spasm of the near reflex (SNR) is a pathological phenomenon, which manifests itself by the persistence of the above-mentioned adjustments, which prevents the eye from returning to its relaxed state.

Methods: In this study, we compare the diagnostic and prognostic values of conjunctival and oral biopsies analyzed by DIF in patients with MMP. Sixteen patients with MMP and mucosal involvement as a predominant symptom were classified into three groups based on the clinical picture.
Objective: Visual snow (VS) is a rare clinical entity in neuro-ophthalmology. It is described as the presence of flickering dots affecting the whole visual field, often compared by patients to snow or pixelated television static. Importantly, it can be an alarming symptom for many patients, lowering their quality of life.
