Surgical management of retinal detachment resulting from macular hole in a setting of high myopia

 PURPOSE:To evaluate the anatomical and visual outcomes of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and use of retinal tamponade for retinal detachments resulting from macular hole (MHRD) in highly myopic eyes. METHODS: Twenty-nine highly myopic patients (29 eyes) underwent PPV with ILM peeling and retinal tamponade for MHRD were enrolled. Demographics and best-corrected visual acuity (BCVA) were measured preoperatively and at final follow-up. Anatomical success and macular hole closure were analyzed. RESULTS:Patients' mean age of patients was 58.7 ± 10.6 years, mean follow-up was 11.7 ± 7.4 months. Twenty three eyes (23/26, 88.5%) undergoing primary PPV combined with ILM peeling had successful initial retinal reattachment, including 19 eyes (19/19, 100%) with silicone oil tamponade and in 4 eyes (4/7, 57.1%) with sulfur hexafluoride (C3F8) tamponade. Overall anatomical success was achieved in 27 eyes (27/29, 93.1%). The macular hole closure was observed in 17 eyes (17/26, 65.4%) with final anatomical success. Compared to preoperative BCVA, the mean postoperative BCVA in the eyes with anatomical success was significantly improved (P = 0.007, Wilcoxon signed rank test). CONCLUSION:As a primary or secondary procedure, PPV combined with ILM peeling and usage of retinal tamponade serves as an effective method for MHRD in highly myopic eyes.     

Silicone oil tamponade for persistent macular holes

BackgroundA variety of treatment strategies have been proposed for macular holes that persist or recur after surgery, and the debate about the best re-treatment approach is ongoing. To allow for a comparison with alternative surgical therapies, we assessed the anatomical and functional outcome of a temporary tamponade with conventional silicone oil in persistent or recurrent full-thickness macular holes.MethodsWe retrospectively investigated consecutive patients with full-thickness macular holes that persisted or recurred following vitrectomy with internal limiting membrane peeling and gas tamponade. All patients received re-treatment by temporary tamponade of silicone oil and were allowed free postoperative positioning. Anatomical closure rate was assessed by optical coherence tomography, and change of best-corrected visual acuity (BCVA) was analyzed.ResultsA total of 33 eyes of 33 consecutive patients were included. Macular hole closure following silicone oil tamponade was achieved in 30 of 33 eyes (90.9%). Median BCVA improved from 1.00 logMAR (interquartile range, 0.60–1.00) to 0.65 logMAR (0.49–1.00; p = 0.010) after silicone oil removal. In patients with macular hole closure, 61.3% exhibited functional improvement with median BCVA changing from 1.00 logMAR (0.70–1.00) to 0.60 logMAR (0.49–1.00; p = 0.0005). Mean minimal linear diameter of macular holes before primary surgery was 391.0 µm (±137.8; range 133–630), and 48.5% of macular holes were >400 µm in diameter.ConclusionsTreatment of persistent or recurrent full-thickness macular holes by temporary conventional silicone oil tamponade without postoperative positioning results in a high closure rate and a significant mean improvement of visual acuity.Subject terms: Outcomes research, Retinal diseases     

Episcleral macular buckling for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole

AIM:To evaluate anatomical and visual outcomes of episcleral macular buckling (EMB) for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole.METHODS: Five cases of EMB for initial failure of retinal reattachment after internal limiting membrane (ILM) peeling and silicone oil tamponade caused by myopic macular hole were retrospectively reviewed. A silicone sponge sutured directly across the macular region was performed on the silicone oil filled eyes. Silicone oil was removed no sooner than 1 month post-EMB. The duration of follow-up time after removal of silicone oil was more than 3 months.RESULTS: Retinas of five eyes were all reattached at the last follow-up. The postoperative vision ranged from counting fingers to 0.08.CONCLUSION: Anatomical results improved after EBM for posterior retinal detachment in silicone oil filled eyes associated with myopic macular hole, which was not evident for visual outcome.

Double peel using triamcinolone acetonide and trypan blue in the management of myopic macular hole with retinal detachment: a case–control study

Purpose: To evaluate the safety and efficacy of double peel using triamcinolone acetonide (TA) and trypan blue (TB) in removing epiretinal tissues in vitrectomy for myopic macular hole with retinal detachment (MHRD). Methods: Prospective interventional case control study. Patients with myopic MHRD underwent vitrectomy with TA‐assisted adherent cortical vitreous (ACV) removal followed by TB‐assisted internal‐limiting membrane (ILM) peeling and gas tamponade. The results were compared with historical control group without the use of any vital dye or TA. Results: Ten eyes of 10 study cases were compared with nine eyes of nine control cases. Mean axial length was 28.3 ± 1.4 mm and 29.6 ± 2.4 mm and mean follow‐up period was 15 months and 42 months for the study group and the control group, respectively. Reattachment rate was 70% in the study group and 44% in the control group. Mean logMAR visual acuity improvement was 0.02 at 6 months and 0.01 at 12 months for the study group (P < 0.05). Transient intraocular pressure rise was observed in seven eyes in the study group and five eyes in the control group. No other complication was noted. Conclusion: Double peel using TA and TB appeared safe and effective in facilitating removal of ACV and ILM in MHRD. It has higher surgical success rate compared with conventional vitrectomy with epiretinal membrane peeling and gas tamponade.     

Outcomes of the Perplexed Surgical Management of Retinal Detachment in Eyes with Coloboma

PurposeTo determine the anatomical and visual outcomes of retinal detachment in eyes with chorioretinal coloboma managed by pars plana vitrectomy, endolaser photocoagulation and silicone oil (SO) tamponade.MethodsRetrospective review of 29 eyes of 29 patients with retinal detachment associated with chorioretinal coloboma. All the cases were managed by vitrectomy procedures concluding with SO tamponade. Encircling band was placed based on pre-operative evaluation and/or surgeon’s discretion. Endolaser photocoagulation was applied around the peripheral retina, all around the peripheral breaks and around the colobomatous area. The outcome measures were evaluated with regard to functional and anatomical success.ResultsThe average age at the time of surgery was 21.76 ± 9.58 years (range, 10–50 years). The mean follow-up duration was 12.28 ± 4.8 months (range, 6–24 months). Primary attached retina was obtained in 21 / 29 (72.4%) eyes after single surgery. Re-detachment in 8 / 29 (27.6%) eyes which required revision surgery was the most frequent postoperative complication followed by raised intraocular pressure in 4 / 29 (13.8%) with SO in situ. Out of 29 eyes, 23 were followed up after the removal of SO. The mean duration of SO removal was 7.91 ± 3.9 months (range, 4–18 months). Implantation of encircling band, lens removal and cryotherapy provided no added advantage. At the final examination, improvement in vision was observed in 21 (72.4%) eyes and the anatomical attachment of the retina was attained in 27 (93.1%) eyes.ConclusionsComplete pars plana vitrectomy, endolaser photocoagulation along with SO tamponade is effective for retinal detachment associated with chorioretinal coloboma. This technique improves the anatomical outcome and helps in regaining significant visual acuity.     

Silicone oil removal after extended tamponade in proliferative diabetic retinopathy—a long range of follow-up

BackgroundTo investigate the anatomical and functional results of silicone oil (SO) removal after an extended period of SO tamponade in eyes having received vitrectomy for proliferative diabetic retinopathy (PDR).MethodsFrom May 2009 to August 2017, clinical records of patients who had vitrectomy for PDR and underwent SO removal were retrospectively reviewed. SO was in principle left in the eye for an extended period of time and would be removed promptly when complications relevant to SO rose, or at the same setting when other intraocular surgeries were performed. Main outcome measures include anatomical outcome, functional outcome, and postoperative complications.ResultsSeventy-four eyes of 64 patients (31 males and 33 females) were analysed. The mean follow-up duration was 35.6 months (ranging from 6 to 99 months, median 32 months). The duration of SO tamponade ranged from 3 to 116 months (mean 26.89 months, median 16 months). Anatomical success was achieved in 95.9% at the last follow-up with best-corrected visual acuity (BCVA) becoming better or unchanged in 81.1%. Postoperative complications included ocular hypertension (>25 mmHg; > 4 weeks) in three eyes (4.1%), macular hole in two eyes (2.7%), transient choroidal detachment in one eye (1.4%), vitreous haemorrhage in four eyes (5.4%) and hyphaema in two eyes (2.7%).ConclusionsThe rate of retinal redetachment after an extended period of SO tamponade and removal was low and the majority of eyes obtained final visual acuity improvement. SO removal after an extended period of tamponade in PDR seems to be safe under proper indications and case selection.Subject terms: Outcomes research, Epidemiology     

Changes in the structure of retinal layers over time in non-arteritic anterior ischaemic optic neuropathy

ObjectiveTo examine structural changes in retinal layers over time in patients with non-arteritic anterior ischaemic optic neuropathy (NAION) and determine the layers that predict visual outcomes.MethodsThe optical coherence tomography parameters in NAION eyes at <2 months, 2–5 months, and 6–18 months from the onset were compared to age-matched normal controls. Generalised estimating equation analysis was used to analyse the changes over time and regression analysis was performed to identify the layer that could predict visual field outcomes.ResultsLess than 2 months from the onset, the peripapillary retinal nerve fibre layer (RNFL) (p = 0.001) and macular outer nuclear layer (ONL) (p = 0.024) were significantly thicker in the NAION eyes than in the control eyes. The average peripapillary RNFL, macular RNFL, and ganglion cell layer and inner plexiform layer (GCIPL) showed reductions in thickness within 2–5 months (peripapillary RNFL: −19.8 μm/month, p < 0.001, macular RNFL: −14.5 μm/month, p < 0.001, GCIPL: −26.8 μm/month, p < 0.001). The change of thickness in temporal and superior peripapillary RNFL, GCIPL, inner nuclear layer (INL), and ONL by 2–5 months was associated with the final visual field results (p = 0.018, p < 0.001, p = 0.040, p = 0.020, and p = 0.002, respectively).ConclusionsThe peripapillary RNFL swelling initially observed started to decrease within 2–5 months along with macular RNFL and GCIPL thinning. The rate of thickness changes in the peripapillary RNFL, GCIPL, INL, and ONL by 2–5 months was associated with visual field outcomes.Subject terms: Optic nerve diseases, Outcomes research     

Choroidal arterial watershed zone topography and its relationship with maculopathy in highly myopic eyes

ObjectivesTo evaluate choroidal arterial watershed zones (CWZ) in highly myopic patients. The relationships between CWZ location and myopic maculopathy location and classification were also examined.MethodsThis retrospective study included 102 consecutive patients who had been diagnosed with myopic maculopathy. Indocyanine green videoangiography was used to evaluate CWZ presence, location, and configuration. Maculopathy signs were used to examine the relationship between CWZ and myopic maculopathy.ResultsVarious CWZ types were identified in 102 of 158 eyes. The CWZ patterns were classified as vertical optic nerve head (vertical-ONH) in 30 eyes, stellate in 29 eyes, vertical-ONH extending to the macula in 28 eyes, horizontal fovea in eight eyes, and vertical parafovea in seven eyes. Choroidal neovascularization occurred within CWZs in 35 of 42 eyes, and macular atrophy was located within foveal CWZs in 20 of 23 eyes. The CWZ type was significantly correlated with mCNV presence (OR = 5.652, P = 0.014).ConclusionsVariations in CWZ topography are associated with myopic maculopathy, particularly in eyes with myopic choroidal neovascularization (mCNV) and macular atrophy, and CWZ is a risk factor for mCNV. This suggests that eyes with macular CWZs are vulnerable to developing myopic maculopathy and are predisposed to mCNV because of ischaemic hypoxia.Subject terms: Eye manifestations, Outcomes research

Study of surgical procedures for retinal detachment with macular hole

PURPOSE: To evaluate the surgical outcome of retinal reattachment, the reattachment rate according to the range of detachment, and postoperative visual acuity for macular hole retinal detachment (MHRD). SUBJECTS AND METHODS: Sixty-eight eyes of 67 patients with MHRD were analyzed. The mean follow-up period was 54 months. RESULTS: Retinal reattachment occurred in 42/68 eyes (62%) after initial surgery. The reattachment rates were 6/23 eyes (26%) in the gas tamponade group, 13/19 eyes (68%) in the vitrectomy group, 23/ 26 eyes (88%) in the group that underwent removal of internal limiting membrane as adjunct to vitrectomy (ILM) group. In the additional surgery, the reattachment rates were 5/9 eyes (56%) in the gas tamponade group, 13 eyes (100%) in the vitrectomy group, 1/2 eyes (50%) in the ILM group, and 6 eyes (100%) in the macular prombe buckling group. No significant differences were seen in the detachment extent-related reattachment rate within the same surgery and the postoperative visual acuity between the groups. CONCLUSION: The results show that removal of ILM contributes to successful reattachment in the initial surgery, and that for non-reattachable eyes, macular buckling in the second surgery is the most reliable method.

结论：PPV联合ILM翻转填塞在治疗高度近视MHRD患者中更有效。     

Técnica modificada del flap invertido superior con vitrectomía versus vitrectomía con pelado de membrana limitante interna para el desprendimiento de retina con agujero macular miópico

PurposeTo evaluate the efficacy of the modified superior inverted internal limiting (ILM) membrane flap technique in retinal reattachment, macular hole closure and external retinal layers restoration in macular hole associated retinal detachment compared to ILM peeling.MethodsRetrospective case series of 10 patients that required pars plana vitrectomy for retinal detachment with macular hole followed for more than 12 months. Data from medical records were retrospectively collected and patients were divided into the superior inverted flap (5 patients) and ILM peeling group (5 patients). We compared best corrected visual acuity (BCVA) before and after surgery, retinal attachment, macular hole closure rate and external retinal layer restoration between groups.ResultsThere were significant improvements in BCVA in both groups before and after surgery, with no differences between the two groups at 12 months after surgery (P = .9). The macular hole closed in 100% of cases in the inverted flap group and 80% of the ILM peeling group with no significant differences between groups. The retina was reattached in 100% of cases in both groups. Only 2 patients in the inverted flap group (40%) had external retinal layer restoration and none in ILM peeling group (P = .62).ConclusionsILM peeling and superior inverted flap techniques are useful for treating retinal detachment with macular hole in myopic eyes.     

Comparison of fovea-sparing and non-internal limiting membrane peeling for retinoschisis with foveal detachment in highly myopic eyes

PurposeTo compare the visual and anatomical outcomes of two different treatment strategies (non-internal limiting membrane (ILM) peeling and fovea-sparing ILM peeling) for retinoschisis with foveal detachment (FD) in highly myopic eyes.DesignA retrospective cohort study.MethodsNinety-five eyes from 92 highly myopic patients with retinoschisis with FD were divided into two groups, including 44 eyes from 43 patients who received 23-gauge, 3-port vitrectomy without ILM peeling (group A) and 51 eyes from 49 patients who received vitrectomy with fovea-sparing ILM peeling (group B). All eyes also underwent cataract surgery.ResultsThere were no significant differences between the two groups in terms of sex, age, diopters, axial length (AL), or central foveal thickness (CFT) before surgery (P > 0.05). One month after surgery, foveoschisis and FD were resolved in 74.47% of the eyes in group B and in only 12.50% of those in group A. Six months after surgery, foveoschisis and FD were resolved in 96.08% of the eyes in group B and in only 72.73% of those in group A (P < 0.05). There were no significant differences between the two groups in terms of BCVA 6 months after surgery. The postoperative complication was macular holes, which were found in seven eyes (15.90%) in group A and in one eye (1.96%) in group B (P < 0.05).ConclusionHighly myopic eyes with FD that underwent fovea-sparing ILM peeling appeared to obtain a better anatomical outcome than those that did not undergo non-ILM peeling. The two procedures obtained similar results in terms of visual function.Subject terms: Retinal diseases, Vision disorders

Myopic foveoschisis with foveal detachment had been treated by vitrectomy without ILM peeling as well as foveal sparing ILM peeling in an attempt to reduce the occurrence of postoperative complications. We performed this retrospective study to assess which is the best method for improving anatomical and functional outcomes, and to reduce the incidence of postoperative macular holes.

Myopic retinopathy is one of the most common causes of irreversible visual impairment and blindness due to the high incidence rate of high myopia [1]. Myopic foveoschisis (MF), a common finding in the macula of highly myopic eyes [2], is one of the major causes of poor vision in eyes with pathologic myopia. Based on optical coherence tomography (OCT) images of the macular region, MF can be divided into three stages: isolated retinoschisis, retinoschisis with foveal detachment (FD), and retinoschisis with a macular hole (MH) [3]. Patients with isolated retinoschisis may have stable vision for a long time. However, when retinoschisis progresses to FD or FD progresses to MH, the patient’s visual acuity drops sharply, and MH retinal detachment may easily develop [4]. Thus, stage II (retinoschisis with FD) is the best time to start surgical treatment.At present, the mainstream treatment for retinoschisis with FD is vitrectomy. Studies have shown that vitrectomy could result in good anatomical and visual outcomes in highly myopic eyes [5–15]. However, how to address the ILM remains controversial. Some studies proposed vitrectomy without ILM peeling and showed that the prevalence of postoperative MH was much lower than that in ILM peeling cases, but the recovery rate may not be satisfactory [12, 16]. In contrast, people who promote ILM peeling believe that it can increase the recovery rate but that postoperative MH may occur (8–18%) [17, 18] and result in poor postoperative VA. Recently, some researchers have proposed a fovea-sparing ILM technique to reduce the risk of iatrogenic MH formation [19–24]. Could fovea-sparing ILM peeling increase the anatomic resolution and reduce the incidence of postoperative MHs in FD patients at the same time? Comparing non-ILM peeling with fovea-sparing ILM peeling, which procedure is better? For these purposes, we designed this study. This study analyzed 95 eyes from 92 patients with MS and FD treated with PPV without ILM peeling or with ILM peeling that avoided the foveal area to determine which procedure is better for treating this disease.     

Factors affecting anatomical and visual outcome after macular hole surgery: findings from a large prospective UK cohort

ObjectivesTo reassess the definition of a large macular hole, factors predicting hole closure and post-surgery visual recovery.DesignDatabase study of 1483 primary macular hole operations. Eligible operations were primary MH operations treated with a vitrectomy and a gas or air tamponade. Excluded were eyes with a history of retinal detachment, high myopia, previous vitrectomy or trauma.ResultsA higher proportion of operations were performed in eyes from females (71.1%) who were ‘on average’ younger (p < 0.001), with slightly larger holes (p < 0.001) than male patients. Sulfur hexafluoride gas was generally used for smaller holes (p < 0.001). From 1253 operations with a known surgical outcome, successful hole closure was achieved in 1199 (96%) and influenced by smaller holes and complete ILM peeling (p < 0.001), but not post-surgery positioning (p = 0.072). A minimum linear diameter of ~500 μm marked the threshold where the success rate started to decline. From the 1056 successfully closed operations eligible for visual outcome analysis, visual success (defined as visual acuity of 0.30 or better logMAR) was achieved in 488 (46.2%) eyes. At the multivariate level, the factors predicting visual success were better pre-operative VA, smaller hole size, shorter duration of symptoms and the absence of AMD.ConclusionsFemales undergoing primary macular hole surgery tend to be younger and have larger holes than male patients. The definition of a large hole should be changed to around 500 μm, and patients should be operated on early to help achieve a good post-operative VA.Subject terms: Outcomes research, Retinal diseases     

Evaluation of the association of macular ganglion cell–inner plexiform layer thickness and myopia in Chinese young adults

PurposeTo describe the distribution of ganglion cell–inner plexiform layer (GCIPL) thickness among Chinese young adults and report whether the decreased GCIPL thickness is associated with myopia.MethodsIn this study, we included Chinese young adults who underwent Cirrus spectral domain-optical coherence tomography (SD-OCT). SD-OCT was used to measure average and minimum GCIPL thickness, and GCIPL thickness at all sectors. Subfoveal choroidal thickness (CT), axial length (AL), and spherical equivalents (SE) were also measured.ResultsA total of 348 eyes were included in the analysis. Average GCIPL thickness showed a significant difference between myopes and emmetropes, with 87.89 ± 3.65 μm for emmetropic groups and 82.65 ± 4.96 μm for myopic groups. The GCIPL thickness was significantly thinner in myopia than in emmetropia at all locations (P < 0.05), affirming that myopia was associated with thinner GCIPL thickness (P = 0.001). The mean subfoveal CT also showed a significant difference between myopes and emmetropes, with 330.57 ± 9.43 μm for emmetropic groups and 265.98 ± 4.12 μm for myopic groups. GCIPL (OR 0.863, 95% CI, 0.785–0.949), AL (OR 2.499, 95% CI, 1.532–4.075) and intraocular pressure (IOP) (OR 1.250, 95% CI, 1.086–1.438) revealed significant associations with myopia. When adjusting for AL, IOP, and anterior chamber depth (ACD) in the myopia subgroup, the GCIPL thickness remained positively associated.ConclusionsIn a specific Chinese young population, myopic eyes have measurably less macular GCIPL thickness than normal eyes. Decreasing GCIPL thickness may be associated with the progression of myopia.Subject terms: Predictive markers, Outcomes research     

Coloboma associated retinal detachment: Anatomical and functional results in the era of microincision vitrectomy surgery with an evaluation of risk factors for a recurrence

Purpose:To analyze the anatomical and visual outcomes of microincision vitrectomy surgery (MIVS) with silicone oil tamponade in eyes having coloboma-related retinal detachment (RD) and evaluate the risk factors for recurrence of RD.Methods:This was a retrospective, multicentric analysis of eyes having coloboma RD undergoing MIVS with silicone oil tamponade between March 2010 and July 2018.Results:We evaluated 148 eyes of 144 patients. The mean age of presentation was 17.4 ± 9.8 years (range: 2–65 years) and the mean follow-up duration was 13.1 ± 13.8 months (range: 3–84 months). The single operation success rate was 88.5% (131 eyes), with an overall successful outcome achieved in 90.5% (134 eyes). Recurrence of RD occurred in 17 eyes (11.5%) over a mean duration of 2.59 ± 3 months. The risk of recurrence was found to be higher in eyes where relaxing retinectomy (RR) was performed (odds ratio [OR]: 3.22; P = 0.05). A statistically significant improvement in vision was noted in the majority of cases from logMAR 1.85 ± 0.34 preoperatively to logMAR 1.33 ± 0.6 post-surgery (P = 0.002).Conclusion:MIVS with silicone oil tamponade provided an anatomical success rate of 90.5% in eyes with coloboma RD with a significant improvement in visual acuity. Eyes in which RR was performed were susceptible to higher rates of re-detachment.

Amniotic membrane for covering high myopic macular hole associated with retinal detachment following failed primary surgery

AIM: To evaluate the therapeutic effect of amniotic membrane (AM) for covering high myopic macular hole associated with retinal detachment following failed primary surgery. METHODS: Seventeen eyes of 17 patients whose axial length was more than 29 mm suffered from macular hole (MH) or MH associated with retinal detachment (RD), and had previously surgery of pars plana vitrectomy (PPV) with internal limiting membrane (ILM) peeling and silicone oil (SO) tamponade. Half a year after the surgery, optical coherence tomography (OCT) showed that MH did not heal in all 17 eyes and RD was still maintained in 13 eyes of these 17 eyes. We performed SO removal combined with AM covering on macular area and C3F8 tamponade, and phacoemulsification combined with intraocular lens implantation simultaneously cataract eyes. We followed up these patients for one year. RESULTS: In all 17 eyes, SO was removed successfully, MHs were healed and RDs were reattached. One eye (5.89%, 1/17) had AM shifted half a month after surgery and underwent a second surgery to adjust the position of the AM and supplement C3F8. After surgery, the visual acuity (VA) improved in 15 eyes (88.24%, 15/17), no change in two eyes (11.76%, 2/17). No serious complications occurred in all eyes. CONCLUSION: AM covering is helpful to rescue the previous failure surgery of high myopic MH.     

Spontaneous resolution of macular edema after silicone oil removal

AIM:To investigate the macular changes in eyes filled with silicone oil (SO) and course of these changes after SO removal.METHODS:A retrospective optical coherence tomography scan review was conducted for twenty-four patients who underwent uncomplicated pars plana vitrectomy with SO tamponade for complex retinal detachments were detected with optical coherence tomography before, and one week, one month and three months after SO removal.RESULTS:Mean duration of SO tamponade was 3.6±1.0mo (range:3-7mo). Cystoid macular edema (CME) was detected in 3 eyes before SO removal. Submacular fluid was represented in 1 eye before silicone SO removal. Resolution of CME and submacular fluid was achieved 1mo after SO removal in all eyes. Mean best corrected visual acuity (BCVA) was 1.15±0.65 (range, hand movement to 0.2) before SO removal in the eyes without macular changes. After SO removal, the mean BCVA values at 1wk and 1 and 3mo, and 0.82±0.23, 0.76±0.21, and 0.70±0.19, all of which were significantly better than baseline (P=0.030, 0.017, 0.006 respectively). In the eyes with macular CME and subretinal fluid the mean BCVA was significantly improved at 3mo after SO removal compared with baseline (P=0.037).CONCLUSION:Decreased visual acuity in eyes filled with SO could be caused by macular complications due to SO. CME and subretinal fluid may resolve without any additional macular surgery after SO removal.
