AIM: To observe the clinical effect of phacoemulsification and posterior chamber intraocular lens ( IOL) implantation in the treatment of unilateral high myopia combined with age-related cataract.
METHODS: A retrospective clinical study was carried out in a single ophthalmology center. All patients diagnosed of unilateral high myopia with age- related cataract were performed phacoemulsification and posterior chamber IOL implantation. The axial length of operation eye was ≥27mm, and the axial length of unoperated fellow eye was≤25mm. Visual acuity and complications were followed up for 1, 7d, 1, 3mo postoperative.
RESULTS:Thirty-three patients with average age 68. 8±9. 26 (41-87) y were enrolled in this study, 7 cases were men, 26 cases were women. The mean axial length of operation eyes was 29. 44±1. 80(27. 1-32. 71) mm and the mean axial length of unoperated fellow eyes was 23. 39±0.92 ( 21. 72 - 24. 90 ) mm. The average axial length difference of binocular eyes was 6. 06±1. 97(2. 78-9. 92) mm. The best corrected visual acuity ( BCVA ) increased from 0. 02±0. 02(light perception~0. 12) preoperatively to 0. 20±0. 20 ( 0. 02 - 0. 8 ) at 3mo postoperatively. There was statistically significant difference (t= -5. 278, P<0. 05). Among the 10 patients whose axial length difference of binocular eyes was 2. 01 - 5. 00mm, 60% of their postoperative BCVA were >0. 3. Among the 13 patients with binocular axial length difference of 5. 01-7. 00mm, 46.2% of BCVA were >0. 3,46.2% achieved 0. 05-0. 25. Another 10 patients of binocular axial length difference between 7. 01-9. 99mm, 90% of BCVA were <0. 3, of which 40% were<0. 05. No complications occurred during operative and postoperative .
CONCLUSION: Phacoemulsification and posterior chamber IOL implantation can effectively improve the postoperative visual acuity and it is safe for unilateral high myopic patients combined with age-related cataract. The recovery of visual acuity is related with binocular axial length difference.

BACKGROUND:There have been many studies on the diagnosis of osteoporotic vertebral compression fractures. However, there are few studies on the diagnostic methods of fracture in different periods. OBJECTIVE:To comparatively analyze the application value of high-intensity magnetic resonance imaging (MRI) and single photon emission computed tomography combined with CT scan image fusion (SPECT-CT) in the diagnosis of osteoporotic vertebral compression fractures. METHODS:Clinical data of 35 patients with osteoporotic vertebral compression fractures were retrospectively analyzed, including 56 vertebrae. There were 14 males and 21 females, with an average age of 72.6 years. The course of disease was within 3 weeks in 22 patients, belonging to acute fractures. The course of the disease was between 4 and 12 weeks in 10 patients, belonging to the subacute fractures. The course of disease was 6 months in 3 patients, belonging to the fracture healing period. Al patients were tested with high-intensity MRI and SPECT-CT examination, and were treated with vertebroplasty or percutaneous kyphoplasty. The Fisher exact method was used to compare the two diagnostic methods in the diagnosis of vertebral fracture. RESULTS AND CONCLUSION:(1) In the 56 responsible vertebral bodies, 32 vertebral bodies belonged to the acute-stage fractures, and 24 vertebral bodies belonged to the non-acute-stage fractures. In al the fractures, MRI diagnosed 49 segments;SPECT-CT diagnosed 52 segments. The sensitivity of SPECT-CT testing was higher than MRI, and its specificity was less than MRI. There was a high consistency of diagnosis between fractures. (2) In the 32 acute vertebral fractures, the two tests diagnosed 29 segments. The sensitivity of SPECT-CT was higher than that of MRI, but its specificity was lower than that of the MRI. There was a high consistency between the diagnoses of fractures. (3) In the 24 non-acute vertebral fractures, MRI diagnosed 20 segments;SPECT-CT diagnosed 23 segments. SPECT-CT was more sensitive than MRI;the specificity of SPECT-CT was lower than MRI. There was a high consistency between the two diagnoses of fractures. (4) There was a high consistency in the MRI and SPECT-CT examination to determine the fracture of different periods of responsibility of the vertebral body, but the sensitivity of SPECT-CT is higher than MRI examination;SPECT-CT is an effective inspection method in the diagnosis of vertebral fractures.
