未经评估:评估早期白内障患者的主观视觉功能并评估其手术适应症。
UNASSIGNED:将眼睛分为对照组(无白内障的A组)和两个早期白内障组(2.0≤OSI<3.0的B组和3.0≤OSI<4.0的C组)。客观散射指数(OSI),调制传递函数截止频率(MTF截止),和Strehl比率(SR)值用于测量目标视觉功能。对比敏感度(CS)和问卷得分(QOL和VF-14)表征了主观视觉功能。比较三组的上述视觉功能。分析B组和C组术后视觉功能,评估手术效果。
未经评估:本研究包括92名受试者(126只眼)。B组各项客观视功能均明显优于C组(均P<0.01),但不如A组(均P<0.01)。除1.5c/dCS外,A组主观视功能明显优于B、C组(均P<0.05),但是B组和C组之间没有显着差异。至于B组和C组接受手术的眼睛,术后所有视功能明显改善(P<0.05),除1.5c/dCS外,C组术后三组间差异无统计学意义。
UNASSIGNED:OSI<3.0的早期白内障患者的主观视功能可能受损,其客观视功能在统计学上优于OSI≥3.0的患者。与OSI≥3.0的患者一样,这些患者可以从手术中受益。主观视觉功能可作为这些患者的手术指征。
UNASSIGNED: To evaluate the subjective visual functions of early cataracts patients and assess their surgical indications.
UNASSIGNED: Eyes were separated into a control group (Group A without cataract) and two early cataracts groups (Group B with 2.0 ≤ OSI < 3.0 and Group C with 3.0 ≤ OSI < 4.0). The objective scatter index (OSI), modulation transfer function cut-off frequency (MTF cut-off), and Strehl ratio (SR) values were applied to measure objective visual functions. The contrast sensitivity (CS) and scores of the questionnaires (QOL and VF-14) characterized subjective visual functions. Above visual functions were compared among three groups. Postoperative visual functions in Group B and C were analyzed to assess the outcome of surgery.
UNASSIGNED: Ninety two subjects (126 eyes) were included in the study. All objective visual function in Group B were significantly better than Group C (all P < 0.01), but worse than Group A (all P < 0.01). Except for 1.5 c/d CS, subjective visual function in Group A were significantly better than Group B and C (all P < 0.05), but there was no significant differences between Group B and C. As for eyes that underwent surgery in Group B and C, all visual functions significantly improved after surgery (P < 0.05), except for 1.5 c/d CS in Group C. There were no significant differences among the three groups after surgery.
UNASSIGNED: The subjective visual function can be impaired in early cataracts patients with OSI < 3.0, whose objective visual functions were statistically better than patients with OSI ≥ 3.0. These patients can benefit equally from surgery as patients with OSI ≥ 3.0. Subjective visual functions can be used as surgical indications for these patients.
