Abstract:
Objective To observe the relationship between morphology of ciliary body and glaucoma with ultrasound biomicroscopy (UBM). Methods Eighty shallow-anterior chamber patients and 80 normal-anterior chamber patients were enrolled as shallow-anterior chamber group and control group, respectively. All patients were greater than 40 years old. The shallow-anterior chamber group included 28 patients of acute angle-closure glaucoma (AACG subgroup), 26 patients of chronic angle-closure glaucoma (CACG subgroup), and 26 patients of primary angle-closure suspects (PACS subgroup). Both eyes of all patients were checked with UBM, and position of each eye on sagittal and coronal section of superior, nasal, inferior and temporal were recorded. Then ciliary process height (CPH), ciliary process thickness (CPT), ciliary process interval (CPI), ciliary process number (CPN), A angle and α angle were measured. Furthermore, the difference between shallow-anterior chamber group and control group, the difference between AACG, CACG and PACS subgroup were compared, as well as the difference between PACS subgroup and control group, and the correlation between A angle and α angle was analyzed. Results Compared with control group, CPH and CPT of shallow-anterior chamber group increased, while CPI, CPN, A angle and α angle decreased (P＜0.05). Except CPH and CPN between CACG and PACS subgroup, there were significant differences of parameters between subgroup of AACG, CACG and PACS (P＜0.05). CPH of PACS subgroup increased than those of control group, while CPI, CPN, A angle and α angle decreased (P＜0.05). There was positive correlation between A angle and α angle. Conclusion Morphologic parameters of ciliary process may be sensitive indexes which can early screen primary angle-closure glaucoma.
