Significance: Sarcoidosis is a variable, multisystem granulomatous disease, which can affect many organs including the lungs, lymph nodes, and eyes. It is difficult to differentiate sarcoidosis and tuberculosis because of their similar clinical and pathological features.
Purpose: This study aimed to describe a sarcoidosis case with typical ocular and systemic manifestations combined with suspected tuberculosis infection.
Case Report: A 30-year-old Chinese man, initially diagnosed with tuberculosis, presented with typical ocular sarcoidosis during antituberculosis therapy. The ocular surface, anterior chamber, anterior chamber angle, ciliary body, vitreous, optic disc, and lacrimal gland of the patient all exhibited manifestations of sarcoidosis, although optic disc involvement has rarely been reported. Typical ocular sarcoidosis manifestations and positive responses to corticosteroid therapy of the patient helped us reach the diagnosis of systemic sarcoidosis. The patient was followed up for 48 months and showed significant improvement of miliary nodules and lymph nodes in both lungs. However, the appearance of uveitis in the right eye persisted because of nonadherence to steroid treatment.
Conclusions: This case shows the importance of ophthalmic evaluation in the diagnosis and management of sarcoidosis and supports a possible role of Mycobacterium tuberculosis in the pathogenesis of sarcoidosis.

The surface of the eye is constantly exposed to the external environment and is affected by atmospheric conditions and air pollution, and dry eye is a typical ocular surface disease. The aim of this study is to determine whether there are seasonal differences in the number of dry eye operations in Japan and to investigate whether meteorological conditions and air pollutants are related to. The operations were examined using the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB) database from fiscal years 2019 to 2021.

Mutations in the gene ABCA4 coding for photoreceptor-specific ATP-binding cassette subfamily A member 4, are responsible for Stargardts Disease type 1 (STGD1), the most common form of inherited macular degeneration. STGD1 typically declares early in life and leads to severe visual handicap. Abca4 gene-deletion mouse models of STGD1 accumulate lipofuscin, a hallmark of the disease, but unlike the human disease show no or only moderate structural changes and no functional decline.

Introduction: While most head movements in daily life are active, most tools used to assess vestibular deficits rely on passive head movements. A single gain value is not sufficient to quantify gaze stabilization efficiency during active movements in vestibular deficit patients. Moreover, during active gaze shifts, anticipatory mechanisms come into play.

The fovea, a pit in the retina, is crucial for high-acuity vision in humans and is found in the eyes of other vertebrates, including certain primates, birds, lizards, and fish. Despite its importance for vision, our understanding of the mechanisms involved in fovea development remains limited. Widely used ocular research models lack a foveated retina, and studies on fovea development are mostly limited to histological and molecular studies in primates.

Mutations in the Rhodopsin (RHO) gene are the main cause of autosomal dominant retinitis pigmentosa (adRP), 84% of which are pathogenic gain-of-function point mutations. Treatment strategies for adRP typically involve silencing or ablating the pathogenic allele, while normal RHO protein replacement has no meaningful therapeutic benefit. Here, we present an adenine base editor (ABE)-mediated therapeutic approach for adRP caused by RHO point mutations in vivo.
