ABSTRACT
Streff syndrome is a non-malingering visual disturbance commonly affecting near and color vision, which is prevalent in the younger population. This case report presents Streff-like syndrome in a middle-aged woman. A 47-year-old woman with underlying major depressive disorder presented with bilateral reduced vision and a constricted visual field for one week. These symptoms were accompanied by additional neurological complaints of headache, weakness, and numbness triggered after a stressful event that affected her work performance. Examinations revealed reduced vision more toward near, diminished red saturation, color vision deficiencies, and bilateral tubular visual fields. Notably, the relative afferent pupillary defect was negative, with both anterior and posterior segments normal. Neuroimaging and inflammatory workup results were within normal limits. An additional +1.00 lens improved her symptoms and visual acuities. Collaborative management involving psychiatry, neurology, and ophthalmology, including psychotherapy, led to significant symptom improvement. At the five-month follow-up, the patient experienced a complete resolution of her visual symptoms. Although Streff syndrome is a primary visual problem, additional psychogenic factors may add to variable cases. This case underscores the importance of recognizing stress-induced psychogenic manifestation, particularly in patients with underlying mental health conditions, and emphasizes an interdisciplinary management approach.
ABSTRACT
PURPOSE: To evaluate parents' performance in using the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) Vision Screening App (application) as a vision screening tool among preschool children and to evaluate the reliability of this app. METHODS: A total of 195 5- and 6-year-old preschoolers were recruited from children attending Hospital Selayang, Selangor, Malaysia, to test the app. Uncooperative children and those with visual acuity of >logMAR 0.6 were excluded. Results from parents and the screening doctor using the app (Lea symbols) to test visual acuity were compared to each other and to gold standard vision testing by an optometrist using the Lea symbols chart. RESULTS: Children 5 years of age represented 46.7% of the study population. The mean age of parents was 37.27 ± 7.68 years. Bland-Altman scatterplot agreement between assessors mainly was within the 95% confidence interval for bilateral eyes screening. Parents obtained a sensitivity of 86.6% (right vision) and 79.5% (left vision) and specificity of 78.9% (right vision) and 71.8% (left vision). Parents took a mean of 191.2 ± 70.82 seconds for bilateral screening. The intraclass correlation coefficient between optometrist and parents in bilateral eyes screening was good (P < 0.001). Cronbach's α for all three assessors was >0.7, indicating high internal reliability of the app. Most parents (178/195 [91.3%]) strongly agreed on the app's acceptability and ease of use. CONCLUSIONS: The AAPOS Vision Screening App used by parents is a promising tool for visual acuity screening among Malaysian preschool children and a reliable app for vision screening.
