To determine whether binocular B class driving licence (BBCDL) holders over 50 years old are in compliance with the BBCDL criteria for visual acuity, to determine the age-based prevalence of ophthalmological disorders reducing visual acuity in this group, and to investigate whether periodic ophthalmological examinations are needed in licence holders over 50 years of age.
This prospective study enrolled 451 adults over 50 years old having a BBCDL. The study subjects were categorized into 3 age groups as group 1 (51-60 years), group 2 (61-70 years), and group 3 (over 71 years).
The mean age of the subjects was 60.02±7.27 years; 338 (74.9%) were male and 113 (25.1%) were female. The BBCDL criteria were met by 353 (78.3%) subjects whereas 98 (21.7%) subjects did not meet them. Eighty-four (85.7%) of 98 patients not meeting BBCDL criteria still drove. The mean age of the subjects meeting BBCDL criteria (58.82±6.77 years) was significantly lower than the subjects not meeting them (64.34±7.40 years) (p<0.001). The most common pathologies in the individuals still driving despite not meeting BBCDL criteria were senile cataract (38.5%) and diabetic retinopathy (23.1%) in group 1, senile cataract (55.3%) and diabetic retinopathy (14.9%) in group 2, and senile cataract (63.6%) and senile macular degeneration+senile cataract (18.2%) in group 3.
More than a fifth of individuals over 50 years old did not meet the BBCDL criteria, due predominantly to senile cataract, and the majority of these individuals continue to drive. Therefore, we believe that individuals over 50 years old who have a BBCDL should undergo periodic ophthalmological examinations.
确定50岁以上的双眼B类驾驶执照（BBCDL）持有者是否符合BBCDL的视力标准，确定该群体中因眼科疾病导致视力下降的年龄别患病率，并调查50岁以上的执照持有者是否需要定期进行眼科检查。
这项前瞻性研究纳入了451名持有BBCDL的50岁以上成年人。研究对象被分为3个年龄组，即第1组（51 - 60岁）、第2组（61 - 70岁）和第3组（71岁以上）。
研究对象的平均年龄为60.02±7.27岁；男性338名（74.9%），女性113名（25.1%）。353名（78.3%）受试者符合BBCDL标准，而98名（21.7%）受试者不符合。98名不符合BBCDL标准的患者中，有84名（85.7%）仍在开车。符合BBCDL标准的受试者的平均年龄（58.82±6.77岁）显著低于不符合标准的受试者（64.34±7.40岁）（p<0.001）。尽管不符合BBCDL标准但仍在开车的个体中，最常见的病变在第1组为老年性白内障（38.
