Convergence insufficiency (CI) is a common and distinct binocular vision disorder. However, there is a lack of consensus regarding the treatment most appropriate for Cl. Possible treatment modalities include base-in prism, pencil pushup therapy (PPT), reading glasses, home-based vision therapy/orthoptics (HBVT), and office-based vision therapy/orthoptics (OBVT). The purpose of this study was to investigate the care process for Cl by surveying eyecare professionals regarding the most common treatment modalities used by both optometrists and ophthalmologists across the United States.
Surveys requesting doctors to indicate which treatment(s) they prescribed and believed to be most effective for symptomatic CI patients were mailed to 863 optometrists and 863 ophthalmologists in the United States.
Fifty-eight percent of the optometrists responded to the survey; the most common treatment prescribed was PPT (36%) followed by HBVT (22%) and OBVT (16%). For the ophthalmologists (who had a 23% response rate), the most common treatment prescribed was PPT (50%) followed by HBVT (21 %) and base-in prism (10%).
This survey suggests that most eyecare practitioners prescribe PPT as the initial treatment for CI.
集合不足（CI）是一种常见且独特的双眼视觉障碍。然而，对于最适合CI的治疗方法尚未达成共识。可能的治疗方式包括底向内棱镜、铅笔俯卧撑疗法（PPT）、阅读眼镜、家庭视觉治疗/视光学（HBVT）和门诊视觉治疗/视光学（OBVT）。本研究的目的是通过调查眼保健专业人员关于美国验光师和眼科医生最常用的治疗方式，来研究CI的护理过程。
向美国863名验光师和863名眼科医生邮寄调查问卷，要求医生指出他们为有症状的CI患者开的并认为最有效的治疗方法。
58%的验光师回复了调查；最常用的治疗方法是PPT（36%），其次是HBVT（22%）和OBVT（16%）。对于眼科医生（回复率为23%），最常用的治疗方法是PPT（50%），其次是HBVT（21%）和底向内棱镜（10%）。
这项调查表明，大多数眼保健从业者将PPT作为CI的初始治疗方法。
