Purpose: To report an occult intraocular foreign body mimicking choroidal melanoma.
Methods: Medical records and imagings of the patient were retrospectively reviewed.
Case Description: A 76-year-old male was referred to our ocular oncology clinic with a suspicious hyperpigmented retinal lesion in the left eye. Biomicroscopy showed aphakia and peripheral iridectomy in the left eye. Fundoscopy revealed a pigmented, slightly elevated lesion on the macula of the left eye surrounded by diffuse atrophy. B-scan ultrasonography showed a preretinal hyperechoic lesion with posterior shadowing. There was no choroidal mass in B-scan or optical coherence tomography (OCT) imaging. On further questioning, it was disclosed that the patient had been hit by an iron fragment in the left eye forty years ago.
Conclusion: Choroidal melanoma is a vision- and life-threatening intraocular malignant tumour. Various neoplastic, degenerative, and inflammatory conditions can simulate choroidal melanoma. A previous history of penetrating ocular trauma should lead the surgeon to re-evaluate a diagnosis of melanoma.

Background/aim: Mucosa-associated lymphoid tissue (MALT) lymphomas occur in not only the ocular adnexa, but rarely in the sclera or uvea. Histopathological confirmation contributes to a better understanding of the pathogenesis and treatment. We report a case of uveoscleral MALT lymphoma with angle-closure glaucoma.

Objective: This study compared ocular and cervical vestibular evoked myogenic potentials (oVEMP and cVEMP) among individuals with Parkinson's disease (PD) without dizziness, with nonspecific dizziness (dizziness without orthostatic hypotension), or with dizziness combined with orthostatic hypotension.
Materials And Methods: We prospectively analyzed 30 of each of the three types of individuals who were admitted to Yongchuan Hospital of Chongqing Medical University (Chongqing, China) between June 2022 and April 2023. The three groups received oVEMP and cVEMP measurements using an electromyography-evoked potential system.
Naturalistic reading of multi-page texts elicits spatially extended modulation of oscillatory activity in the right hemisphere.

The study of the cortical basis of reading has greatly benefited from the use of naturalistic paradigms that permit eye movements. However, due to the short stimulus lengths used in most naturalistic reading studies, it remains unclear how reading of texts comprising more than isolated sentences modulates cortical processing. To address this question, we used magnetoencephalography to study the spatiospectral distribution of oscillatory activity during naturalistic reading of multi-page texts.

Significance: Artificial tears remain the cornerstone for managing dry eye disease. The current study's real-world efficacy test of carboxymethylcellulose (CMC), polyethylene glycol (PEG) 400, or sodium hyaluronate (SH)-based lubricants highlights their similar effects on noninvasive tear film parameters over the short term. However, patients reported better relief with SH-based lubricants.

The pupillary direct and consensual reflex is an important non-invasive quick assessment of the neurological state of the eye. Currently, there is no cheap and affordable recording tool for screening and documentation of a relative afferent pupillary defect. We describe how to construct a frugal, do-it-yourself handheld scotopic binocular pupillometer device called Pupilmate.
