OBJECTIVE:
To investigate the value of hand-held retinal optometer and optical coherence tomography (OCT) in predicting postoperative visual acuity in patients with age-related cataract and idiopathic macular epiretinal membrane.
METHODS:
We retrospectively analyzed the data of patients undergoing phacoemulsification combined with intraocular lens implantation for age-related cataract in our hospital from January, 2019 to April, 2020.Preoperative examination detected idiopathic macular epiretinal membrane in 45 of the patients (52 eyes) with lens opacity grade C2N2P1 according to LOCSⅡ lens opacity classification criteria.Based on the thickness of the macular fovea, the eyes were divided into group A (9 eyes) with macular thickness < 300 μm by OCT examination, group B (25 eyes) with macular thickness of 300 to 400 μm, and group C (18 eyes) with macular thickness >400 μm.The best corrected visual acuity and retinal visual acuity before operation and the best corrected visual acuity on the first day and at 3 months after the surgery were compared among the 3 groups.The consistency between the preoperative retinal vision and the best corrected vision at 3 months after the surgery was analyzed.
RESULTS:
The best corrected visual acuity at one day and 3 months after the surgery differed significantly from that before the surgery in all the 3 groups (
CONCLUSIONS
For patients with cataract and idiopathic macular epiretinal membrane, phacoemulsification combined with intraocular lens implantation can improve postoperative vision.Hand-held retinal optometer can accurately assess postoperative vision in patients with stage C2N2P1 cataract.Patients with a macular thickness >400 μm caused by idiopathic macular epiretinal membrane are likely to have poor postoperative visual outcomes.

PURPOSE: To discuss the unique morphology and origin of epiretinal proliferation associated with macular hole (EPMH) occasionally observed in full-thickness macular hole (FT-MH) or lamellar hole (LH) and to introduce the perifoveal crown phenomenon encountered when removing this unusual proliferative tissue. METHODS: Sixteen patients showing EPMH in spectral domain-optical coherence tomography were selected from 212 patients diagnosed with MH, LH, FT-MH, impending MH, macular pseudohole, or epiretinal membrane between January 2013 and December 2014. Of the 212 patients included for clinical analysis, 33, 23, 11, 7, and 190 exhibited LH, FT-MH, impending MH, macular pseudohole, and epiretinal membrane, respectively. We reviewed visual acuity, macular morphology, and clinical course. Surgical specimens were analyzed histologically. RESULTS: EPMH presented as an amorphous proliferation starting from the defective inner/outer segment (IS/OS) junction covering the inner macula surface. Among the 16 patients with EPMH, 11 underwent vitrectomy, and all exhibited the intraoperative perifoveal crown phenomenon. EPMH tissue was sampled in three patients, one of whom had more tissue removed than intended and showed delayed recovery in visual acuity. Despite hole closure, IS/OS junction integrity was not successfully restored in four of 11 patients. Five patients were followed-up without surgical intervention. Visual acuity slightly decreased in three patients and did not change in one patient, while the remaining patient was lost during follow-up. Among the three perifoveal crown tissues obtained, two were successfully analyzed histologically. Neither tissue showed positivity to synaptophysin or S-100 protein, but one showed positivity to cytokeratin protein immunohistochemical staining. CONCLUSIONS: EPMH exhibited a distinct but common configuration in spectral domain-optical coherence tomography. An epithelial proliferation origin is plausible based on its configuration and histological analysis. Perifoveal crown phenomenon was observed when removing EPMH during vitrectomy.

OBJECTIVES: To assess the inadvertent intraocular retention of perfluorocarbon liquid (PFCL) after vitreoretinal surgery and their complications. METHODS: We retrospectively reviewed the medical records of 108 patients who underwent vitreoretinal surgeries using intraoperative PFCL (perfluoro-n-octane (C8F18), 0.69 centistoke at 25degrees C, PERFLUORN(R), Alcon, USA) and the removal of PFCL through fluid-air exchange. The analysis was focused on the occurrence of intraocular retained PFCL, diagnoses,surgicalprocedures,andcomplications. RESULTS: Retinal detachment (51 cases, 47%) was the most common surgery which used PFCL intraoperatively. Other causes were vitreous hemorrhage (24 cases, 22%), posteriorly dislocated lens (22 cases, 21%), and trauma (11 cases, 10%). Intraocular PFCL was found in a total of 9 (8.3%) eyes. PFCL bubbles remained in anterior chamber and vitreous cavity were observed in 4 cases and subretinal retained PFCL was observed in 5 cases. Three of 5 cases of subretinal PFCL exhibited in subfoveal space. Among the three subfoveal cases, macular hole developed after PFCL removal in 1 case, epiretinal membrane in the area where had been PFCL bubble. However, we observed no complications in 1 case of subfoveal PFCL that was removed by surgery. PFCL in anterior chamber and vitreous cavity were in 4 cases. CONCLUSIONS: The presence of subfoveal PFCL might affect visual and anatomic outcomes. However, subfoveal PFCL may induce visual complications, and therefore requires special attention.

PURPOSE: To evaluate the accuracy of postoperative refractive outcomes of combined phacovitrectomy for epiretinal membrane (ERM) in comparison to cataract surgery alone. MATERIALS AND METHODS: Thirty-nine eyes that underwent combined phacovitrectomy with intraocular lens (IOL) implantation for cataract and ERM (combined surgery group) and 39 eyes that received phacoemulsification for cataract (control group) were analyzed, retrospectively. The predicted preoperative refractive aim was compared with the results of postoperative refraction. RESULTS: In the combined surgery group, refractive prediction error by A-scan and IOLMaster were -0.305+/-0.717 diopters (D) and -0.356+/-0.639 D, respectively, compared to 0.215+/-0.541 and 0.077+/-0.529 in the control group, showing significantly more myopic change compared to the control group (p=0.001 and p=0.002, respectively). Within each group, there was no statistically significant difference in refractive prediction error between A-scan and IOLMaster (all p>0.05). IOL power calculation using adjusted A-scan measurement of axial length based on the macular thickness of the normal contralateral eye still resulted in significant postoperative refractive error (all p<0.05). Postoperative refraction calculated with adjusted axial length based on actual postoperative central foveal thickness change showed the closest value to the actual postoperative achieved refraction (p=0.599). CONCLUSION: Combined phacovitrectomy for ERM resulted in significantly more myopic shift of postoperative refraction, compared to the cataract surgery alone, for both A-scan and IOLMaster. To improve the accuracy of IOL power estimation in eyes with cataract and ERM, sequential surgery for ERM and cataract may need to be considered.

We report a case of complete surgical resolution of Valsalva retinopathy that manifested as a premacular hemorrhage involving a membrane followed by a macular hole (MH) resulting from the first vitrectomy. A 20-year-old female patient was referred to our hospital due to sudden vision loss in the left eye. Her best-corrected visual acuity (BCVA) in the left eye was hand motion. Fundus photographs and optical coherence tomography (OCT) revealed a premacular hemorrhage. Nine weeks later, the BCVA in the left eye had returned to 20 / 100 and the premacular hemorrhage had completely resolved, but residual sub-internal limiting membrane deposits and a preretinal membrane were present. The preretinal membrane was removed by core vitrectomy and preretinal membrane peeling, but the foveal deposits could not be excised. Two weeks after the first vitrectomy, the deposits resolved spontaneously, but a full-thickness MH was present. Six months after a second vitrectomy with fluid-gas exchange, the BCVA in the left eye had improved to 20 / 25 and OCT showed that the MH had closed. This case illustrates the possibility of MH formation following vitrectomy for Valsalva retinopathy.

OBJECTIVETo assess efficacy of membrane peeling combined with intravitreal injection of bevacizumab in the treatment of macular epiretinal membrane.
METHODSFrom January, 2012 to June, 2013, 33 patients (33 eyes) with the diagnosis of macular epiretinal membrane underwent vitreous surgery and membrane peeling. The patients were randomly divided into intravitreal bevacizumab group (IVB group) and non-intravitreal bevacizumab group (non-IVB group). All the patients underwent standard three-port vitrectomy and peeling of epiretinal membrane, with intravitreal injection of 1.5 mg bevacizumab at the end of operation in IVB group. The best corrected visual acuity and optical coherence tomography (OCT) were examined before and after the treatment. The patients were followed up for 3-14 months (mean 6.5 months).
RESULTSMacular epiretinal membranes were successfully peeled during operation in all the patients without postoperative intraocular infection or bleeding. Fifteen eyes received vitrectomy combined with intravitreal injection of bevacizumab, and 18 underwent only vitreous operation and membrane peeling. At the end of the follow up, the visual acuity improved in 11 eyes (73.3%) in IVB group, as compared to 13 eyes (72.2%) in the non-IVB group (P=0.627). Central macular thickness decreased by 143∓62 µm in IVB group and by 96∓28 µm in non-IVB group, showing a significant difference between the two groups (t=5.564, P<0.01).
CONCLUSIONVitrectomy and membrane peeling combined with intravitreal injection of bevacizumab can promote the recovery of macular morphology but not visual function, and its clinical use still needs to be tested in a long-term and large-sample randomized controlled study.

PURPOSE: To assess the clinical outcomes in idiopathic epiretinal membrane (ERM) patients after vitrectomy and ERM removal with or without additional indocyanine green (ICG)-assisted internal limiting membrane (ILM) peeling. METHODS: The medical records of 43 patients with an idiopathic ERM that underwent vitrectomy and ERM removal between July 2007 and April 2010 were reviewed. The patients were divided into two groups: triamcinolone-assisted simple ERM peeling only (group A, n = 23) and triamcinolone-assisted ERM peeling followed by ICG staining and peeling of the remaining internal ILM (group B, n = 20). RESULTS: No difference was found between the two groups in terms of visual acuity, macular thickness, P1 amplitude or implicit time on multifocal-electroretinogram (mfERG) at six and 12 months postoperatively. In group B, ICG staining after ERM peeling demonstrated that the ILM had been removed together with the ERM in 12 eyes (60%), and all 12 eyes showed punctate retinal hemorrhages during ERM peeling. There was no recurrence of an ERM in either group. CONCLUSIONS: Additional procedures involving ICG staining and ILM peeling during ERM surgery do not appear to have an additive effect on the clinical outcomes in terms of visual acuity, retinal function based on mfERG, or recurrence rate.
