“…It has been published that choroidal thickness increases in cases of AVF, decreasing after its closure. 7 In our report, choroidal thickness could only be measured in the second case, and we measured a decrease in 134 μm during our follow-up, as previously published.…”

Arteriovenous fistulas (AVFs) are abnormal shunts between the arterial and venous vascular systems. These usually produce ocular pain, increased intraocular pressure (IOP), and diplopia. Less frequently, they may cause retinal changes with visual impairment. Our purpose is to illustrate different retinal manifestations of AVF. We report the multimodal imaging study of three cases with retinal changes due to AVF, showing neurosensory retinal detachment, macular oedema, and macular ischemia. In conclusion, AVF may appear with different ophthalmic alterations. While usually increased IOP and diplopia are our main concerns, retinal study is mandatory, since a myriad of morphologic abnormalities might be present.

“…EDI-OCT is a noninvasive technique that is used to evaluate choroidal thickness and morphology in these diseases [ 2 ]. Shinohara et al [ 3 ], have already reported that the relationship between an increased choroidal thickness by EDI-OCT and choroidal congestion in CCF by using fluorescein angiography, laser speckle flowgraphy and brain angiography before and after embolization of the CCF, however, serous retinal detachment was not present.…”

BackgroundWe report the enhanced depth imaging optical coherence tomography (EDI-OCT) characteristics and variations in a patient with subretinal fluid secondary to a carotid cavernous fistula.Case presentationA 59-year-old man presented with blurred vision in his right eye. Venous congestion of the epiescleral and retinal vessels were observed. EDI-OCT disclosed macular subretinal fluid with an increase of choroidal thickness up to 341 μm. Brain and orbital computerized tomography showed an enlarged right superior ophthalmic vein. Orbital magnetic resonance imaging and angiography disclosed a decrease in blood flow, an indirect sign of carotid cavernous fistula. After a 3 months follow-up, spontaneous closure of the fistula occurred. Both the dilation of the conjunctiva and retinal veins improved. EDI-OCT showed resolution of the subfoveal fluid and a reduction of the subfoveal choroidal thickness to 271 μm after a 3 months follow-up and 168 μm after a 8 months follow-up.ConclusionSerous retinal detachment has been described as a rare complication of carotid cavernous fistula. In our patient, EDI-OCT examinations revealed a thicker choroidal thickness when subretinal fluid was present as compared to that observed in the contralateral eye or after subretinal fluid resolution.

“…39 Shinohara et al reported that the choroidal thickness of a patient with carotid cavernous stula (CCF) was increased secondary to the superior orbital vein (SOV) congestion. 40 They suggested that it may cause may lead to increased choroidal pressure and may increase the subfoveal CT. In the present study, we observed that there were signi cant differences in subfoveal CT variations between the two groups.…”

Background To evaluate the safety and effectiveness of the Visian Implantable Collamer Lens (ICL) implantation in high myopic patients with inactive Graves’ ophthalmopathy (GO) by observing the changes of choroidal thickness (CT). Methods Eight patients (16 eyes) with high myopia accompanied with inactive GO were selected as the experimental group (group A) and 18 high myopic patients (36 eyes) without GO were selected as a control group (group B). The outcomes of uncorrected visual acuity (UCVA), best spectacle-corrected visual acuity (BCVA), safety index, efficacy index, intraocular pressure (IOP), vault, corneal endothelial count, and choroidal thickness (CT) were observed. The values of CT were measured using swept-source optical coherence tomography (SS-OCT) scans. Results The UCVA and BCVA in all operated eyes were better than that before surgery. The postoperative safety index and efficacy index were 1.23 and 1.19 in the group A, respectively, and 1.26 and 1.21 in the group B, respectively. In both groups, foveal CT increased significantly in high myopic patients at 2 hours and at 3 months after surgery, compared to preoperative values. The same tendencies were observed in the inner nasal and outer nasal regions. Compared with patients without GO, the increase of CT was more obvious in GO patients, 2 hours postoperatively (P = 0.006) and 3 months postoperatively (P = 0.011). Conclusions The ICL implantation is safe and effective in high myopic patients with inactive GO. Subfoveal and nasal CT may be useful parameters for monitoring the activity of GO patients.
