Associated Factors Analysis For Predicting Anatomical Outcomes And Postoperative Visual Acuity After Vitrectomy For Idiopathic Macular Hole

Objective:To evaluate the associated factors for predicting anatomical outcomes and postoperative visual acuity of idiopathic macular hole(IML)after vitrectomy.Methods:A total of 35 eyes in 35 IMH patients underwent a virectomy?ILM peeling and gas filling surgery were included in this study.The patients included 34 females and 1 males,with the mean age of(59.6±5.4)years.The slit lamp?indirect ophthalmoscope?best corrected vision acuity and spectral domain optical coherence tomography(SD-OCT)were measured for all the patients.The base diameter(BASE)?height(H)?minimum diameter(MIN)?diameter of IS/OS absence(DIOA).Anatomical outcomes were divided into 3 levels based on the results of their OCT pictures.A:good healing;B:bridge-shaped healing;C:poor healing.Postoperative visual acuity were divided into 3 groups:Visual improved group?Visual unchanged group?Visual decreased group.The mean follow-up time was(8.7±4.4)months.The multiple factors related with predicting anatomical outcome and visual acuity including age,sex,preoperative corrected vision acuity,BASE,H,MHCI,MIN,THI,DHI were analyzed.Results:A total of 35 eyes in 35 IMH patients underwent a virectomy?ILM peeling and gas filling surgery were included in this study.The patients included 34 females and 1 males,with the mean age of(59.6±5.4)years.The slit lamp?indirect ophthalmoscope?best corrected vision acuity and spectral domain optical coherence tomography(SD-OCT)were measured for all the patients.The base diameter(BASE)?height(H)?minimum diameter(MIN)?diameter of IS/OS absence(DIOA).Anatomical outcomes were divided into 3 levels based on the results of their OCT pictures.A:good healing;B:bridge-shaped healing;C:poor healing.Postoperative visual acuity were divided into 3 groups:Visual improved group?Visual unchanged group?Visual decreased group.The mean follow-up time was(8.7±4.4)months.The multiple factors related with predicting anatomical outcome and visual acuity including age,sex,preoperative corrected vision acuity,BASE,H,MHCI,MIN,THI,DHI were analyzed.Conclusion:(1)MHCI has the best correlation with anatomical outcomes,It can be considered a key factor for predicting anatomical outcomes of IMH after vitrectomy.(2)preoperative DIOA?preoperative BCVA(logMAR)?THI can be considered key factors for predicting postoperative BCVA(logMAR).(3)BCVA has a significantly correlation with DIOA directly,no matter preoperative or postoperative.The length of DIOA is the key fact for predicting BCVA.
