ObjectiveTo analyze the clinical characteristic, treatment and prognosis of traumatic macular holes resulted from ocular contusion. MethodsThe clinical data of 47 cases with traumatic macular hole was retrospectively reviewed. The general condition of the patients was summarized, optical coherence tomography and multifocal electroretinogram (mfERG) were used to evaluate anatomic and functional outcomes. The patients were divided into observation group and surgery group by the treatment they received, and the prognosis was evaluated. ResultsTraumatic macular hole occurs mainly in male. In the observation group, the mean diameter of macular hole was(490.0±86.9)μm. During the 12 month follow-up, the holes in 7 cases (33.3%) were closed spontaneously, Vision and diameters of 14 cases (57.1%) maintained stable for a long time, the vision of 1 case (3.3%) declined mildly and the diameter of 1 case (3.3%) enlarged slightly. Visual acuity was improved significantly at last follow-up (Z=-2.40, P < 0.05). The amplitudes of N1 wave of mfERG increased both in central fovea and macular area(t=13.30, 5.06;P < 0.05).These data suggests that the macular function was recovered well. In the surgery group, the mean diameter of macular hole was(643.3±125.0)μm and statistically larger than that of the observation group (t=-4.76, P < 0.05). At the last follow-up, visual acuity were not improved significantly (Z=-1.79, P > 0.05). The amplitudes of N1 wave in 6 cases (23.1%) improved merely and the difference was not statistically significant(t=1.98, P > 0.05).These data suggests that the macular function was recovered slightly only in a few patients. ConclusionsA part of the patients with smaller diameters of macular holes may close spontaneously, and they may get better visual acuity. Vitrectomy may help to close the macular holes in some severe cases, but the improvement of functional outcomes is not significant.
ObjectiveTo investigate the course of the idiopathic macular hole (IMH) clinically diagnosed as at stage Ⅰ-Ⅳ by optical coherence tomography (OCT), and analyze the relationship between the posterior vitreous detachment (PVD) and the course of IMH. MethodsHadn′t undergone any operation, periodical OCT were performed on 72 eyes of 58 patients with IMH at stage Ⅰ-Ⅳ confirmed by Gass standard and the features of OCT images.ResultsThe longest follow-up period was 43 months (average 13.4 months), and the examine times of OCT on each eye were between twice to 10 times (average 4.7 times). During the followup period, 23 eyes were in stage I in which 9 (39.1%) developed to stage II and 2 had recovered normal curve of fovea after PVD; 19 were in stage II in which 13 (68.4%) developed to Ⅲ-Ⅳ and 1 had closed hole after PVD; 11 were in stage III in which 5 (45.5%) developed to stage IV and 1 had partly closed hole 12 months later. The images of OCT showed that the process of macular hole was consistent with the course that vitreous depart from retina from the circumference of fovea till entire posterior detachment.Fifteen affected eyes in this series of patients had undcrygong surgical treatment due to serious progression of IMH in follow-up period. ConclusionsThere is a close relationship between the formation and development of macular hole and the occurrence of PVD. OCT can show the progress of the macular hole directly and offer an important technique in diagnosis, classification and surgical treatment of IMH. (Chin J Ocul Fundus Dis, 2005,21:79-82)
Objective To evaluate and compare the prognosis of idiopathic macular holes (IMH) and traumatic macular holes (TMH) treated by pars plana vitrectomy (PPV).Methods The clinical data of 72 IMH eyes and 55 TMH eyes, which were treated by PPV between November 2001 and December 2007, were retrospectively reviewed. The visual outcomes and macular anatomic closure were evaluated, and their relationships with prognostic factors including the size of macular hole (MH), preoperative visual acuity (VA) and duration of disease were analyzed.Results The closure rate of IMH (100.0%) was significant higher than that of TMH (85.5%) (P=0.001). The postoperative VA of IMH and TMH were (0.25plusmn;0.02) and (0.21plusmn;0.21) respectively,both significantly increased compare to their preoperative VA (t=-6.841,-4.093; P=0.000). VAincreased IMH and TMH eyes had same VA (chi;2=3.651,P=0.07). PrePPV VAge;0.1 IMH eyes had better outcomes than PrePPV VA<0.1 IMH eyes (chi;2=12.04, P=0.001), while PrePPV VA had no effects on TMH outcomes (chi;2=0.371,P=0.486). IMH eyes with small holes had better outcomes (t=2.476,P=0.016), and TMH eyes with small holes had better closure (t=-4.042, P<0.001). The duration of disease had no significant influence on TMH visual (chi;2=0.704, P=0.401) and anatomic (chi;2=0.166, P=0.684) outcomes. Conclusions PPV is an effective treatment for MH. The closure rate of IMH is higher than that of TMH. The diameter of MH and preoperative VA are major factors for IMH outcomes, and the duration of disease and preoperative VA have no effects on postoperative VA in TMH.

Appropriate classification and staging is the basis for the diagnosis and treatment of idiopathic macular hole (IMH). According to the appearance of vitreous and retina determined by optical coherence tomography, IMH can be classified as primary or secondary IMH, and IMH with or without vitreous attachment; Vitreous attachment can be further classified as vitreomacular adhesion or vitreomacular traction. According to the measured horizontal diameter, IMH can be classified as large, middle and small IMH. This new classification system and comprehensive parameters improve the traditional Ⅳ-stage theory, with a better description of the occurrence and development of IMH process. It should be used as the general principal to guide IMH classification, evaluation of surgical indications, selection of operative method, and estimation of surgical outcome. Ganglion cell damage caused by internal limiting membranes (ILM) peeling is the major concern in the IMH vitreoretinal surgery. For complicated and large IMH, inverted ILM flapping can improve the closure rate; ILM peeling and postoperative face-down posture are not necessary for IMH less than 250um in diameter. The current vitreoretinal surgery trend to treat IMH is personalized surgical treatment, following the existing evidence-based medical evidence, and based on the new classification information, ocular and systemic features of each patient.
