Abstract
Methods::
In a consecutive series of 21 patients (21 eyes) with traumatic macular holes, visual acuity in international standard, flatten intraocular pressure and fundus examination were checked; Optical coherence tomography (OCT) was used to check the structure of macular holes; Mutifocal ERG and P-VEP in some cases were also detected. Following-up time was4~12 months.
Results::
At the first consultation of the 21 cases, the detected hole diameters of OCT were from 60 to 1207 um (average 468 um). Visual acuity was from 0.1 to 0.3. 18 patients first visited to a doctor among 2 month after traumatized. Among of them, 7 cases (7 eyes) were pure macular holes, and all spontaneously closured. Their vision increased up to 0.4~0.9. 14 cases (14 eyes) combined the different vitreous hemorrhage and choroidal-retinal hemorrhage. The open clear-edged macular hole weren’t closured, and retina was not detachment. The retinal pigment epithelium (RPE) of fundus was atrophy. 3 cases were diagnosed macular hole 10 and 20 years respectively, their visual function and anatomical structure of macular weren’t changed obviously. There were irregular organized cords under and above the retina of fundus.
Conclusions::
Traumatic macular hole mainly occur among the young, their vision and the rate of retina detachment was low. The tissue regeneration of young is strong and purely traumatic macular hole really has a high spontaneous cure rate. The close follow-up were the first choice of treatment for this disease. The spontaneous cure rate of macular hole was influenced by the retinal hemorrhage and severe choroidal-retinal contusion. The medical usefulness and vitreous retinal surgery of the treatment and the above standpoint needs the big sample to be further researched.
