CME leads to severe visual impairment in patients with various retinal diseases, such as diabetic retinopathy, retinal vascular occlusion, choroidal neovascularization, and uveitis. Although various retinal conditions lead to CME, a shared pathogenesis of CME is involved in these diseases. Accordingly, the pathogenesis of CME based on vasogenic mechanisms is first discussed in this review, including vascular hyperpermeability, leukostasis, and inflammation. We then describe cytotoxic mechanisms based on retinal Müller cell dysfunction. This comprehensive review will provide an understanding of the pathogenesis of CME for potential therapeutic strategies.展开更多

METHODS： Group sequential observational comparative study. After phacoemulsification, patients received two months for topical treatment of either diclofenac sodium, bromfenac or nepafenac. All patients received concomitant topical tobramycin 0.3% and topical prednisolone 1%. We measured CME using optical coherence tomography（OCT） central foveal thickness, macular thickness and total macular volume. RESULTS： We enrolled 243 patients from January to June 2015, and 35% received diclofenac, 32.9% bromfenac and 32.1% nepafenac. When we compared pre-operative to three weeks to two months, bromfenac was more effective in reducing foveal volume（21.3 and 35.4 mm3, respectively）, compared with the diclofenac（1.3 and 11.5 mm3, respectively）, and the nepafenac group, became more edematous 6.4 and 5.3, respectively. Totally 133 patients completed the post-surgical satisfaction questionnaire. Patients complained of eye stickiness in 13.8% whom we gave nepafenac, versus 10.3% whom we gave diclofenac sodium, and in 0 whom we gave bromfenac. CONCLUSION： Bromfenac is the best tolerated and is more effective than diclofenac and nepafenac in reducing CME after phacoemulsification.展开更多

Methods: We report two uncommon cases of cystoid macular edema within a few weeks of routine selective laser trabeculoplasty. Results:Visual acuities and macular thicknesses of the two cases returned to baseline after medical treatment,but in one case, the cystoid macular edema persisted for months. Conclusion:Cystoid macular edema after selective laser trabeculoplasty is fortunately a rare complication, but it might be more common in patients with predisposing factors, and it can be resistant to treatment.展开更多

METHODS: A retrospective case series of 38 eyes of 35 patients is described. Of these, 17 eyes of 16 patients displayed foveal regeneration after resolution of CME, and 6 eyes of 6 patients displayed CME with ILM detachment. Eleven eyes of 9 patients displayed other kinds of foveal and retinal disorders associated with ILM detachment. RESULTS: The pattern of edematous cyst distribution, with or without a large cyst in the foveola and preferred location of cysts in the inner nuclear layer or Henle fiber layer(HFL), may vary between different eyes with CME or in one eye during different CME episodes. Large cysts in the foveola may be associated with a tractional elevation of the inner foveal layers and the formation of a foveoschisis in the HFL. Edematous cysts are usually not formed in the ganglion cell layer. Eyes with CME and ILM detachment display a schisis between the detached ILM and nerve fiber layer(NFL) which is traversed by Müller cell trunks. ILM detachment was also found in single eyes with myopic traction maculopathy, macular pucker, full-thickness macular holes, outer lamellar holes, and glaucomatous parapapillary retinoschisis, and in 3 eyes with Müller cell sheen dystrophy(MCSD). As observed in eyes with MCSD, cellophane maculopathy, and macular pucker, respectively, fundus light reflections can be caused by different highly reflective membranes or layers: the thickened and tightened ILM which may or may not be detached from the NFL, the NFL, or idiopathic epiretinal membranes. In eyes with short single or multiple CME episodes, the central fovea regenerated either completely, which included the disappearance of irregularities of the photoreceptor layer lines and the reformation of a fovea externa, or with remaining irregularities of the photoreceptor layer lines. CONCLUSION: The examples of a complete regeneration of the foveal morphology after transient CME show that the fovea may withstand even large tractional deformations and has a conspicuous capacity of structural regeneration as long as no cell degeneration occurs. It is suggested that the regenerative capacity depends on the integrity of the threedimensional glial scaffold for foveal structure stabilization composed of Müller cell and astrocyte processes. The glial scaffold may also maintain the retinal structure after loss of most retinal neurons as in late-stage MCSD.展开更多

METHODS： In this cross-sectional study, DME was classified by OCT as diffuse retinal thickness（DRT）, cystoid macular edema（CME） and serous retinal detachment（SRD） and the relationship between the systemic risk factors and DME patterns was evaluated. RESULTS： Of the 57 patients with DME, 21（36.8%） had DRT, 24（42.1%） had CME and 12（21.0%） had SRD. Microor macro-albuminuria was significantly higher in the DRT pattern（61.9%） compared with the SRD（50.0%） and CME patterns（25.0%; P=0.040）. Hemoglobin A1 c（Hb A1 c） level was significantly higher and patients were younger in the DRT pattern group（P=0.034, P=0.032）. Best corrected visual acuity was the worst and central macular thickness was the thickest in the CME pattern group. CONCLUSION： Micro-or macro-albuminuria may be more frequent and Hb A1 c level may be higher in patients with DRT. These patients are also seen to be younger than patients with non-DRT.展开更多

METHODS: Electronic medical records of cataractsurgery patients (single surgeon) were reviewed fromJanuary 2018 to September 2021. The rate of postoperativecomplications including prolonged and/or recurrentpostoperative inflammation, endophthalmitis, cystoid macularedema (CME), and intraocular pressure (IOP) was comparedbetween the patients receiving combinative therapy andpatients receiving drops only. RESULTS: Totally 596 patients and 1057 eyes(Combinative-Therapy group 493 and Drop-Only group 564)were included in this study. Using combination therapyreduced the relative risk of postoperative inflammationby 26.9% (16.6% Combinative-Therapy vs 22.7% Drop-Only, P=0.013). The incidence of endophthalmitis was 0in Combinative-Therapy group vs 0.5% in Drop-Only group(relative risk reduction 100%), although not statisticallysignificant (P=0.10). The incidence of severe IOP spikeswas not significantly different between Combinative-Therapy (2.4%) and Drop-Only (1.6%) groups (P=0.33).The relative risk of postoperative CME was 51.4% less inthree months follow up visit in Combinative-Therapy group,although not statistically significant (P=0.07). The visualoutcome 1-month postop. (best corrected visual acuity) wassignificantly better in Combinative-Therapy (logMAR 0.10)compared to Drop-Only (logMAR 0.14) groups (P=0.02) whilethe baseline visual acuity was not significantly different. CONCLUSION: The combinative approach oftranszonular triamcinolone-moxifloxacin plus perioperativeeyedrops is an effective method to minimize postoperativeinflammation, with better visual outcomes. It couldpotentially reduce the risk of postoperative endophthalmitisand CME (near-significant P-values;larger studies couldanalyze better considering low incidence).展开更多

A total of 71 eyes(71 cases) with cystoid macular edema(CME) were included in the study. Macular pigment(MP) was evaluated using HRA2(infrared) IF and FA models. The density of MP was graded into three categories: without, partial, and normal amount of MP. A comparison was made between the baseline(before the first administration) level and at the fourth month, following three consecutive intravitreal lucentis injections every month. The morphology and distribution of MAF, and the density and distribution of MP were regarded as the main outcome measures. At the baseline visit, all eyes with CME had petaloid/irregular-shaped MAF in the macular area(100%). No MAF was detected in the control eyes(0). There was significant difference in MAF between the CME and normal groups(P=0.000). At the fourth monthly visit, normal levels of MP density without MAF was detected in 68 eyes(95.8%) with the best corrected spectacular visual acuity increasing to at least 1 line accordingly. We conclude that macular MAF can be used as a follow-up parameter for patients with CME. MP and MAF can indirectly reflect the fovea cone function.展开更多
