“…[ 2 3 ] Cases of cystoid macular edema (CME) with a cherry-red spot in acute CRAO without impaired choroidal circulation have also been reported in elderly patients. [ 4 ] In non-arteritic CRAO, the initial presenting vision could be NLP in 7% of the eyes without impaired choroidal circulation. [ 5 ] CRAO causes acute ischemic insult to the inner retinal layers, resulting in diffuse posterior pole intraretinal edema.…”

“…In the present study, macular changes including small cystoids were detected in subacute-stage RAO. Such macular findings are uncommon but have been described in earlier case reports [ 16 , 17 ]. Cystoid macular edema, which is extracellular arising between the inner nuclear and outer plexiform layer, resulting in a “flower petal” appearance, can be seen in acute phase of RAO.…”

“…Cystoid macular edema, which is extracellular arising between the inner nuclear and outer plexiform layer, resulting in a “flower petal” appearance, can be seen in acute phase of RAO. Ng WY et al described that the outer retinal layer is involved as well in CRAO [ 16 ]. The pathomechanism is unclear; however, the occurrence of cystoid macular edema means that CRAO does not only affect the inner retina but the outer retinal layer and outer blood-retinal barrier.…”

Development of macular retinoschisis long after the onset of retinal arterial occlusion (RAO): a retrospective study

et al. 2018

BackgroundTo describe a retrospective study of macular retinoschisis that developed long after the onset of retinal artery occlusion (RAO) using optical coherence tomography (OCT).MethodsWe describe changes in macular findings and visual acuity (VA) of 29 patients (21 males and 8 females, mean age: 66.1 ± 16.9 years) with RAO (18 branch RAOs [BRAOs] and 11 central RAOs [CRAOs] who visited Osaka Medical College Hospital over an 8-year period based on a medical chart review.ResultsThe mean VA (logMAR) increased from 1.06 ± 1.08 (CRAO: 2.04 ± 0.99; BRAO: 0.37 ± 0.40) at the first visit to 0.71 ± 0.87 (CRAO: 1.46 ± 0.86; BRAO: 0.18 ± 0.30) at the final visit. Macular OCT revealed swelling or hyper-reflectivity of the inner retina in the early phase of RAO and retinal thinning in the late phase. Among the 29 patients, two patients (a patient with BRAO and a patient with CRAO) developed macular retinoschisis about 1 year after RAO onset. The VA of the patient with BRAO was 20/300 at the first visit, and it improved to 20/25 two days after onset following eye massage and anterior chamber paracentesis. However, his VA worsened, declining from 20/25 to 20/50, and retinoschisis occurred 13 months after RAO onset. The patient with CRAO showed macular changes including small cystoids at the first follow-up visit more than 3 weeks after onset and developed retinoschisis 11 months after the first visit. In addition, two patients with BRAO and one patient with CRAO developed macular changes including small cystoids 3 weeks after onset, with the BRAO complicated by retinal vein occlusion. In the CRAO patient, the cystoid macular edema was resolved 1 month after the first visit.ConclusionsMacular retinoschisis is unusual, but a possible complication of RAO that can develop long after the onset of the occlusion, potentially resulting in renewed VA deterioration.

“… 9 In our analysis, however, 19% of the eyes had cystic fluid accumulation within the ONL. Ng et al 22 described a case of CRAO in an elderly female in which cystoid edema was noted in the ONL on OCT during the acute phase. More recently, Estawro et al 23 reported on two cases with CRAO that developed IRF, one during the acute phase in which the fluid localized to the ONL, and the other during the chronic phase in which fluid localized mainly to the INL.…”

Purpose To examine the prevalence and distribution of fluid within a cohort of eyes with acute central retinal artery occlusion (CRAO) and non-arteritic anterior ischemic optic neuropathy (AION) using optical coherence tomography (OCT). Methods A retrospective analysis of patient records and OCT imaging. Patients presenting with acute CRAO or AION who had available macular OCT imaging and no co-morbidities known to cause macular fluid were included in the analysis. Baseline characteristics, visual acuity (VA), and fluid presence and distribution among the retinal layers were recorded. Results In the 16 eyes with acute CRAO, fluid was noted in 5 eyes (31%), which was mainly subretinal (3 eyes) or intraretinal located within the outer retinal layers (3 eyes). Only one eye had inner retinal cysts. Of the 11 eyes with acute AION, fluid was present in 8 eyes (73%). Subretinal fluid was noted in 4 eyes and extended to the foveal area in 3 of them, and outer retinal versus inner retinal cysts were noted in 6 versus 3 eyes, respectively. None of the eyes showed hard exudate deposition. In the small subset of eyes with CRAO and macular fluid that were followed-up, VA improved, while in eyes with AION, VA remained stable. Conclusion Macular fluid on OCT is not an uncommon feature of acute CRAO and AION and is mainly distributed within the outer retinal layers or subretinal space. Fluid is an understudied feature of retinal and optic nerve head infarction and may have a role in predicting neuronal damage extent and visual outcome.
