| Abstract |
|
Macular hole can be quantitated by measuring its diameter, depth and volume with Heidelberg retina tomograph(HRT). In this study, effectiveness of macular hole surgery was investigated using HRT. Patients with good preoperative visual acuity showed better visual improvement after surgery. The macular holes of stage 1 and stage 2 had better visual prognosis than those of stage 3 and stage 4. Idiopathic holes had better visual prognosis than traumatic holes. Following surgery, the diameters of the macular holes were significantly decreased in eyes with postoperative visual improvement, and significantly increased in eyes with decrease in visual acuity. The diameter of a macular hole is a good indicator for the correlation of vision in macular hole surgery. Initial visual acuity and stage of macular holes were the most significant prognostic factors. |
