  • The changes of retinal thickness in idiopathic macular hole eyes after vitrectomy combined with internal limiting membrane peeling surgery

    ObjectiveTo observe the changes of retinal thickness in idiopathic macular hole eyes after vitrectomy combined with internal limiting membrane peeling. MethodsThe study included 40 eyes in 40 consecutive patients with idiopathic full-thickness macular holes who underwent vitrectomy and internal limiting membrane peeling. There were 10 males (10 eyes) and 30 female (30 eyes), the average age was (63.60±6.26) years, the average disease duration was (6.00±3.53) months. All patients were examined by spectral-domain optical coherence tomography to measure the foveal retinal thickness, parafoveal retinal thickness and every quadrant in 1, 3, 6 months after surgery. ResultsCompared foveal retinal thickness after 1 month with 3 month, the difference was significant (F=4.527, P=0.013). But foveal retinal thickness were not significantly different in 3 months and 6 months after surgery (F=2.031, P=0.971). The difference of average parafoveal retinal thickness between 1 month, 3 months and 6 months after surgery was not significant (F=2.011, P=0.139). The retinal thickness of the operated eyes were not significantly different from the normal fellow eyes in 1 month after surgery (t=0.651, P=0.519). And the foveal retinal thickness of the operated eyes and the normal fellow eyes are significantly different in 3 months and 6 months after surgery (t=-2.563, -2.524; P=0.015, 0.016). The thickness of temporal were thicker than other quadrant in 1 month, 3months and 6 months after surgery (t=-3.701, -4.612, -4.125; P=0.014, 0.006, 0.009). ConclusionThere is a transient increase in the foveal retinal thickness after macular hole surgery.

  • The changes of macular microstructure in large idiopathic macular hole after vitrectomy combined with internal limiting membrane transplantation or internal limiting membrane peeling

    ObjectiveTo observe the different changes of macular microstructure in patients with large idiopathic macular hole (IMH) treated with vitrectomy combined with internal limiting membrane (ILM) transplantation or not. MethodsForty eyes in 40 consecutive patients with giant IMH (≥500 μm) were included in the study. Twenty eyes received vitrectomy with ILM transplantation (ILM transplantation group) and others with ILM peel off (ILM removal group). During the operation, a proper size of the ILM was removed and filled in the bottom of the macular hole. The age, duration of disease and the ocular laterality of the two groups of patients were not statistically significant (P>0.05). Minimum resolution angle in logarithmic (logMAR) best corrected visual acuity (BCVA) and frequency domain optical coherence tomography (SD-OCT) scan were examined. There was no statistically significant difference in logMAR BCVA, average defect diameter of photoreceptor ellipsoid (IS/OS) and average defect diameter of external limiting membrane (ELM) between two groups (t=0.128, 1.452, 1.321; P>0.05). The logMAR BCVA and SD-OCT were examined on 1, 3, 6, 12 months postoperatively. ResultsOn 1 month after the surgery, there was no statistically significant difference in logMAR BCVA, average defect diameter of IS/OS and average defect diameter of ELM between two groups (t=1.226, 1.435, 1.018; P>0.05). On 3, 6, 12 months after the surgery, compared with ILM removal group, the logMAR BCVA (t=2.059, 2.871, 2.415) increased and the average defect diameter of IS/OS (t=2.070, 2.110, 2.121) and ELM (t=2.034, 3.647, 3.556) significantly reduced in ILM transplantation group (P<0.05). On 1 month after the surgery, there was statistically significant difference in CRT between two groups (t=2.113, P<0.05). On 3, 6, 12 months after the surgery, there was no statistically significant difference in CRT between two groups (t=0.428, 0.847, 0.849; P>0.05). ConclusionCompared with vitrectomy combined with ILM peeling surgery, the diameter of IS/OS and ELM defect were significantly decreased after vitrectomy combined with ILM transplantation in the patients with large IMH.
