【Title】 Treatment of Dry Eye Disease - Current recommendations according to DEWS III report

【Journal】 Klin Monbl Augenheilkd

【Authors】 Christina Jacobi

【Summary】 This review summarizes current recommendations for dry eye disease (DED) management based on the 2025 DEWS III report. DED is a multifactorial, symptomatic ocular surface disorder involving tear film instability, hyperosmolarity, inflammation, and neurosensory abnormalities. Given its diverse causes and clinical manifestations, management requires detailed history-taking and differentiated diagnostic assessment. Rather than relying exclusively on a stepwise treatment algorithm, current recommendations emphasize individualized, etiology-oriented combination therapy. Particular attention is directed toward identifying systemic contributing factors, recognizing neuropathic pain components, and promoting interdisciplinary collaboration to optimize patient care.

【Title】Dry Eye Symptoms Among Adults Aged 40 Years and Older in Gaza During Humanitarian Crisis: Prevalence and Associated Factors

【Journal】Disaster Med Public Health Prep

【Authors】Mohammed Aljarousha; Mohd Zulfaezal Che Azemin; et al.

【Summary】This community-based cross-sectional study surveyed 296 adults aged ≥40 years in Gaza during the humanitarian crisis. Using the Arabic Ocular Surface Disease Index (OSDI), the study found that 97.3% reported dry eye symptoms. Living in tents and being aged ≥70 years were associated with slightly higher symptom prevalence. Higher psychological distress scores were associated with greater symptom severity, while participants in the South/displaced group reported a greater symptom burden than those surveyed in the North. The findings highlight the high burden of dry eye symptoms in this sample, although the convenience sampling design and lack of direct environmental exposure measurements limit generalizability and causal interpretation.

【Title】The eyes and Parkinsonian syndromes

【Journal】Rev Neurol (Paris)

【Authors】B S Chen; D S Sandlin; V Biousse

【Summary】This review examines ophthalmic manifestations of Parkinsonian degenerative syndromes, including Parkinson disease, progressive supranuclear palsy, multiple system atrophy, corticobasal degeneration, and dementia with Lewy bodies. Key features include ocular motor abnormalities, eyelid dysfunction, dry eye disease, visual hallucinations, and visuospatial impairment, which may affect quality of life, functional independence, and fall risk. Recognizing these manifestations may support differential diagnosis and identify treatable visual problems. Management approaches include ophthalmological assessment, orthoptic interventions, refractive correction, and ocular surface treatment. Emerging tools such as retinal imaging, quantitative eye movement analysis, and tear biomarkers may improve diagnosis and monitoring, although their clinical utility remains under investigation.
