SUMMARY Strabismus is a common disorder in which eyes are not aligned with their optical axis, resulting in an abnormal binocular interaction, thus leading to amblyopia. Accordingly, early detection and diagnosis are mandatory. Despite technology development and constant knowledge growth, the foundations of physiology and the diagnosis of strabismus were set back in the 19 th or early 20 th century and have not changed since. In this paper, a novel, properly tested and evaluated eye-tracking based method for manifest strabismus diagnosis is presented. The evaluation showed the aforementioned method to have both high sensitivity and specificity in detecting manifest strabismus without the need for a skilled examiner, thus being suitable for population screening and highlighting the need for future research regarding testing of latent strabismus.

Acute optic neuritis has the age and sex adjusted incidence of 1-5/100,000 in general population. It is mostly a disorder affecting young Caucasian women (31-32 years). Patients present to a wide range of clinicians including general practitioner, emergency physician, ophthalmologist, neurologist, etc. There are two main clinical presentations of optic neuritis, typical and atypical. It is of great importance to distinguish these two types of optic neuritis in order to detect the underlying etiology and plan appropriate and timely treatment. We present a young female patient (36 years) admitted to Department of Ophthalmology due to visual loss on the left eye. Magnetic resonance imaging showed demyelinating lesions in frontal and parietal lobe, periventricularly, in mesencephalon and right cerebellar hemisphere, and left optic neuritis; magnetic resonance angiography was normal. The patient's history revealed renal dysfunction, hypothyroidism, and miscarriage in the 6 th month of pregnancy due to eclampsia, and Fabry disease in family (mother and two sisters). She was transferred to the Department of Neurology for further evaluation of the demyelinating disorder of the central nervous system. The patient received corticosteroid therapy (methylprednisolone 1 g) for 5 days with regression of visual disturbances on the left eye. After this acute treatment, the question of definitive diagnosis remained, along with further treatment of the underlying cause. Considering renal dysfunction, miscarriage, arterial hypertension, positive genetic and biochemical testing for Fabry disease in close relatives (mother), we suspected that she also had Fabry disease. She was tested and the results were positive. We concluded that optic neuritis was the first sign of Fabry disease in this case, reflecting acute atypical neuroinflammatory disease.

An unruptured giant intracranial aneurysm of the internal carotid artery may tend to present with late ocular symptoms. This is the case of a 58-year-old female patient with a giant unruptured aneurysm of the right internal carotid artery. The patient presented with exclusively progressive reduction of visual acuity and visual field defects due to the mass effect of the growing aneurysm. The rupture of the aneurysm occurred before planned treatment. Clinical suspicion and timely recognition as well as prompt treatment play an important role in the final outcome of the management of giant unruptured intracerebral aneurysms.
