Background: Ocular morbidities associated with rheumatoid arthritis (RA) have not received much attention in Africa, particularly in sub-Saharan Africa. They are among the commonest (40%) extra-articular organ involvement in RA. If undiagnosed, there is a potential risk of them causing visual impairment or blindness. There is no documented study in Uganda on the magnitude of eye disorders among RA patients.
Aim: To determine the spectrum of eye disorders and associated factors among patients with RA attending Mulago National Referral Hospital.
Methods: A hospital based cross-sectional study was conducted among adults with RA attending the rheumatology clinic between July 2021 and September 2021. Clinical and sociodemographic data were collected, and ophthalmologic examinations were performed on all consenting participants. Modified Poisson regression with robust standard error was used to determine factors associated with eye disorders.
Results: Overall, 105 patients with RA were enrolled, of which, 53 (50.5%) had eye disorders. The commonest disorder (54.7%, n=29) was dry-eye syndrome. Factors that were significantly associated with eye disorders were age 36-55 years (aPR 1.56, =0.015), duration of RA >5 years (aPR 1.81, =0.001), use of hydroxychloroquine >5 years (aPR 1.77, =0.041), dose of oral steroids >10 mg/day (aPR 1.49, =0.034), and history of both diabetes and hypertension (aPR 1.87, =0.014).
Conclusion: The prevalence of eye disorders among patients with RA was high, with the commonest being dry-eye syndrome. We recommend that ocular examinations be performed on every patient at the time of RA diagnosis for early detection of eye disorders.

Purpose: To explore the potential correlation between subjective and measured visual function, as well as to analyse the influence of eye disease, socioeconomic factors and emotional dimensions.
Methods: Semi-structured interviews, physical examinations and functional tests (n = 1203). Demographics covered sex, marital status, education, household economy, smoking and alcohol.

Purpose: This study aimed to investigate the role of SIRT4 in retinal protection, specifically its ability to mitigate excitotoxic damage to Müller glial cells through the regulation of mitochondrial dynamics and glutamate transporters (GLASTs).
Methods: A model of retinal excitatory neurotoxicity was established in mice. Proteins related to mitochondrial dynamics, GLAST, and SIRT4 were analyzed on days 0, 1, 3, and 5 following toxic injury.

Purpose: To investigate the effect of Ca2+/calmodulin-dependent protein kinase II (CAMKII) δ subtypes (CAMK2D) on sodium iodate (NaIO3)-induced retinal degeneration in mice.
Methods: Bioinformatics analysis and Western blot experiments were used to screen the significantly differentially expressed genes in age-related macular degeneration (AMD) disease. CAMK2D knockdown and overexpression models were constructed by lentivirus (LV) infection of adult retinal pigment epithelial cell line-19 (ARPE-19) cells in vitro.

A 61-year-old male patient without prior history of ophthalmologic problems presented with pain and redness in the left eye associated with slowly progressive proptosis over the previous 6 months. The patient also had diplopia in rightward and downward gaze. There was no vision loss.

The organ of Corti, located in the inner ear, is the primary organ responsible for animal hearing. Each hair cell has a V-shaped or U-shaped hair bundle composed of actin-filled stereocilia and a kinocilium supported by true transport microtubules. Damage to these structures due to noise exposure, drug toxicity, aging, or environmental factors can lead to hearing loss and other disorders.
