Association Between Visual Acuity, Ocular Pathology and Refractive Error with Computer Vision Syndrome: Cross Sectional University Study in Kenya

Abstract

Background: Numerous factors have been shown to reduce symptomatic and non-symptomatic forms for computer vision syndrome. However, little is known on the impact among computer users diagnosed with severe symptoms of computer vision syndrome. The study assessed whether reduced visual acuity, ocular pathology and refractive error are associated with computer vision syndrome. Methods: A cross sectional university based study in Kenya. Seven hundred and eighty three participants were included in the study. Visual acuity was determined using snellens chart and converted to logMAR chart. Ocular pathology was determined through comprehensive examination using a slit lamp. Computer vision syndrome was determined using a validated questionnaire. Finally Retinoscopy was conducted to determine the type of refractive error. Results: Participants with refractive error above ± 0.50 dioptres had a greater odds, multivariate adjusted ratio 0.73 (95% CI 0.63-0.90) for developing computer vision syndrome. Similar to visual acuity with multivariate adjusted odds ratio of 0.31 (95% CI 0.24-0.47) and ocular pathologies being significantly associated with computer vision syndrome (p=.04). Ocular condition like sub conjunctival hemorrhage was not significantly associated with computer vision syndrome (P=.12). Conclusion: Reduced visual acuity, presence of ocular pathology and refractive error were associated with greater likelihood of computer vision syndrome. Particularly among those who had never had optical correction. Eye care providers are well placed to come up with proper diagnosis of CVS.

Perbedaan Tingkat Kelelahan Mata Pada Mahasiswa Dengan Gangguan Refraksi Dan Tanpa Gangguan Refraksi

“…Penelitian pendukung dengan analisis multivariat didapatkan hasil nilai OR= 7,883 (1,637), artinya responden yang memiliki kelainan refraksi mata memiliki peluang 7,883 kali untuk mengalami kejadian kelelahan mata dibanding responden yang tidak memiliki kelainan refraksi mata. 17 Perbedaan hasil odds ratio dengan penelitian Arianti (2017) dengan hasil OR penelitian tersebut lebih tinggi karena adanya perbedaan dari desain, karakteristik subjek dan pengukuran yang dilakukan. 14 Berdasarkan frekuensi mahasiswa dengan kelelahan mata sebanyak 57 orang didapatkan hasil tingkat kelelahan mata rendah pada penderita gangguan refraksi sebanyak 6 orang (42,9%), tingkat kelelahan mata sedang pada penderita gangguan refraksi sebanyak 20 orang (87%) dan mahasiswa kedokteran dengan gangguan refraksi mengalami tingkat kelelahan mata kategori berat sebanyak 16 orang (80%).…”

“…Gejala-gejala astenopia muncul lebih minimal pada gangguan refraksi yang telah dikoreksi. 17 Perbedaan tingkat kelelahan mata pada mahasiswa kedokteran dengan gangguan refraksi dan tanpa gangguan refraksi. Belum banyak penelitian yang membahas mengenai perbedaan tingkat kelelahan mata pada mahasiswa dengan gangguan refraksi dan tanpa gangguan refraksi, sehingga penelitian ini diharapkan dapat menjadi dasar untuk memecahkan isu tersebut.…”
