To evaluate the long term effect of the corrective surgery in adult strabismus patients with visual impaired, and to study the stability of postoperative alignment and the influence factors.
Retrospective study the alignment, binocular visual, ocular movement and quality of life in 72 adult strabismus patients with visual impaired( the best corrective visual acuity less than 0.3 in one or both eyes). And to compare with these in 79 patients without visual impaired.
The age of patients in visual impaired group was 17~65(29.16±10.96) when underwent corrective surgery. Of these patients, 14 were esotropia with deviation 45.36±20.05PD(18~90PD),58 cases were exotropia with deviation 52.87±17.76PD(12~90PD).The age of patients in control group was 25.62±9.38(15~52) when underwent corrective surgery. Of these patients, 21 were esotropia with deviation 44.6±21.15PD(20~90PD) and 58 cases were exotropia with deviation 48.12±25.04PD(10~160PD). Forty-eight(66.7%, 48/72) and 66 (83.5%,66/79)were defined as “success” at the last follow-up in the visual impaired group and control group, respectively. The difference in success rate between the two group was significant( P=0.013).There were 3 patients and 34 patients achieved normal or partial stereo acuity in visual impaired and control group, respectively. The difference in stereo acuity between two group was significant(P<0.01).The scores of quality of life questionnaire were lower in the visual group than that in the control group(P<0.01).Of the 24 patients defined as “Not success” in the visual group, 22 cases were under-correction and 2 cases were over-correction. The deviation was shift toward to exotropia with 5.6PD(0~18PD) from the 1st post-operative day to the last follow-up in patients of visual group.
About two of three of patients with visual impaired can get long-term successful outcome with corrective surgery.while the stability of the alignment, the binocular vision and quality of life were worse than that in patients without visual impaired.
