Abstract:
Objective To compare the occurrence of the peripheral retinal degeneration in macular hole due to high myopia (>-6.00 D) and trauma.Methods Data of 106 patients (106 eyes) with macular hole undergoing vitrectomy operation were analyzed,and they were divided into two groups according to myopic refractive degree:group A (68 eyes of 68 patients with high myopia) and group B (38 eyes of 38 patients with trauma).The peripheral retinas of all patients were examined carefully through preoperative three-mirror contact lens test and intraoperative the vitrectomy surgery.Results There were 52 eyes with peripheral retinal degeneration in group A,accounting for 76.47%,while group B had 8 eyes with peripheral retinal degeneration,accounting for 21.05% in group B.The occurrence rates of peripheral retinal degeneration between the two groups approached significant difference (x2 =30.48,P =0.000).Among 52 eyes with retinal degeneration in the retina of the group A,non-oppressed whitening degeneration presented in 42 eyes,and the detection rate was 61.76%,lattice degeneration was in 44 eyes,with the detection rate of 64.71%,cystic degeneration in 19 eyes,with the detection rate of 27.94% and other types of degeneration in 15 eyes,with the detection rate of 22.06%.There were 8 eyes with retinal degeneration in the retina of the group B,and non-oppressed whitening degeneration presented in 6 eyes,with the detection rate of 15.79%,lattice degeneration was in 7 eyes,with the detection rate of 18.42%,cystic degeneration in 4 eyes,with the detection rate of 10.53% and other types of degeneration in 2 eyes,with the detection rate of 5.26%.Conclusion The occurrence rate of peripheral retinal degeneration in traumatic patients is obvious lower than that in patients with high myopia.
