Soal selidik kendalian kendiri indeks fungsi visual (VF14) dan korelasinya dengan akuiti visual koreksi terbaik pada warga emas

Kajian ini dilakukan untuk menentukan skor kendalian kendiri indeks fungsi visual (VF14) dan korelasinya dengan akuiti visual koreksi terbaik pada warga emas. Subjek kajian ialah warga emas berumur 60 tahun ke atas yang mengambil bahagian dalam kajian yang sedang dijalankan iaitu“Model Perlindungan Neuro Bagi Penuaan Sihat Di Kalangan Warga Emas (TUA). Akuiti visual diukur dengan menggunakan carta logMAR. Penilaian soal selidik kendalian kendiri diukur menggunakan Indeks Fungsi Visual (VF14) berbahasa Melayu yang telah diubah suai. Seramai 482 (93.05%) daripada 518 subjek kajian telah mengambil bahagian dalam kajian ini. Purata umur subjek kajian ialah 69.18 ± 5.67 tahun dan purata akuiti visual koreksi terbaik ialah logMAR 0.21 ± 0.17. Purata skor VF14 ialah 89.65 ± 13.19. Perempuan mempunyai purata skor VF14 yang lebih rendah jika dibandingkan dengan lelaki (skorperempuan89.21 ± 12.76, skorlelaki90.11 ± 13.65) tetapi tidak ada perbezaan secara statistik (z= -1.09, p= 0.277). Terdapat korelasi yang sederhana tetapi signifikan antara skor VF14 dan akuiti visual koreksi terbaik (r = -0.412, p < 0.01). Kesimpulannya, akuiti visual koreksi terbaik sahaja tidak boleh digunakan sebagai indikator untuk menjelaskan perubahan skor VF14. Kajian ini menunjukkan ia hanya menyumbang kepada 17.2% kepada perubahan skor VF14. Gabungan banyak faktor lain seperti faktor sosio demografik (bangsa, status pendidikan dan masalah kesihatan), sensitiviti kontras dan stereopsis perlu diambil kira apabila menilai fungsi visual yang diukur dengan VF14

Refractive error and visual acuity of elderly Chinese in Selangor and Johor, Malaysia

The first aim of this study was to determine the refractive error and visual acuity of Chinese elderly age 60 and above in Selangor and Johor, Malaysia. The second aim was to determine the percentage of elderly with vision impairment. Participants of this study were from the on-going population-based longitudinal study on neuroprotective model for healthy longevity (TUA) among Malaysian older adults using multistage random sampling. A total of 259 Chinese elderly aged 60 and above from state of Selangor and Johor agreed to participate. Refractive error was determined using autorefractometer Retinomax K-plus followed by subjective refraction. Best corrected visual acuity (VA) was measured using logMAR chart. Analysis was performed on data of 202 participants and the remaining 57 were excluded. Overall percentage of refractive error was higher for hyperopia (54%) compared to myopia (23.2%). High percentage of astigmatism was noted for all age groups (> 50%). Both gender showed similar distribution of refractive status. Mean overall VA was 0.24 ± 0.17 logMAR (≅ 6/9–) and mean VA declined with age. Overall, the percentage of elderly having at least mild vision impairment (> 0.3 logMAR or 6/12) was higher (62.9%) compared to normal vision (≤ 0.3 logMAR). However, percentage of vision impairment (VI) was highest in the mild category compared to others and only one participant had severe VI. This study found a high percentage of Chinese elderly with refractive error. The most common type of refractive error was hyperopia. A high proportion of them had mild vision impairment followed by moderate VI even with best correction. Vision impairment could affect daily life functioning and this effect can be further explored in the future
