“…This finding supports the notion that PAC/PACG induces RVO, rather than the reverse association, although it has been proposed that in some cases of CRVO, vascular engorgement and oedema of the posterior segment results in anterior rotation of the cilio‐lenticular diaphragm, thereby closing a previously narrow but open drainage angle (Grant ; Mendelsohn et al. ; Wu et al. ).…”

Purpose: To investigate the frequency of primary angle closure (PAC) and primary angle closure glaucoma (PACG) in patients with retinal vein occlusion (RVO) based on a hospital population. Methods: A total of 375 consecutive cases newly diagnosed with RVO by fluorescein fundus angiography at a single eye centre in Peking were reviewed. Gonioscopy was performed in all patients. Glaucoma was diagnosed according to the criteria of the International Society of Geographical and Epidemiological Ophthalmology. Retinal vein occlusion was classified as central retinal vein occlusion (CRVO), hemicentral retinal vein occlusion (HRVO), or branch retinal vein occlusion (BRVO), and as arteriovenous crossing RVO (AV-RVO), optic cup RVO (OC-RVO), optic nerve RVO without optical nerve head swelling (NONHS-RVO), or RVO with optical nerve head swelling (ONHS-RVO) based on the site of venous occlusion. Percentage of PAC or PACG for each type of RVO were calculated.Results: PACG had a frequency of 4.1% [95% confidence interval (CI) 2.2-6.9%] in 317 RVO patients [5.3% (95% CI 2.0-11.2%) in CRVO, 8.8% (95% CI 1.9-23.7%) in HRVO, and 1.9% (95% CI 0.4-5.4%) in BRVO]. Primary angle closure (PAC) had a frequency of 2.9% (95% CI 1.4-5.5%) in RVO. PAC/PACG had a frequency of 11.5% (95% CI 6.3-18.9%) in CRVO, 8.8% (95% CI 1.9-23.7%) in HRVO and 3.1% (95% CI 1.0-7.1%) in BRVO. PAC/ PACG was significantly more prevalent in NONHS-RVO [18.9% (95% CI 9.4-32.0%)] than in ONHS-RVO [6.5% (95% CI 2.1-14.5%)], AV-RVO [3.1% (95% CI 0.9-7.8%)], and OC-RVO [2.3% (95% CI 0.1-12.3%)]. Conclusion: The overall frequency of PAC/PACG was much higher in patients with RVO (especially CRVO) than that in the general population. Eyes with PAC/PACG may undergo mechanical changes in the lamina cribrosa of the optic disc, resulting in RVO. Angle-closure conditions should be borne in mind when investigating Chinese patients with RVO.

“…This form of glaucoma must be distinguished from NVG because the treatments and prognoses may differ between the 2 conditions. General Characteristics [24][25] 1) unilateral acute OH with angle-closure and flattening of the anterior chamber, which appears within 1mo of a CRVO attack; 2) the congener eye shows a deep anterior chamber, normal IOP, and a wide open (45º width) anterior chamber angle; 3) transient character; and 4) lack of the intraocular NV. The shallowness of the anterior chamber is due to an abnormal accumulation of blood or transudative fluid from the retinal vessels, in the posterior segment of the eye, that pushes the vitreous and lens forward, blocks the pupil, and leads to angle-closure glaucoma.…”

“…Anti-VEGF agents are beneficial because they act synergistically reversing the increased vascular permeability mediated by VEGF and decreasing the amount of fluid in the posterior portion of the eyeball. Choroidal hemorrhages, massive vitreous hemorrhages, uveal effusions, and PRPs are other causes of transient unilateral flattening of the anterior chamber, with or without angleclosure glaucoma [25] . The reported incidence of non-rubeotic angle-closure glaucoma in patients with CRVO is extremely low (0.68%) [24] .…”

Intraocular pressure modifications in patients with acute central/hemicentral retinal vein occlusions

Intraocular pressure (IOP) modifications in patients with acute central/hemicentral retinal vein occlusions (RVOs) consist in IOP reductions and increases. The IOP reduction is due to a transitional hyposecretory phase of the aqueous humor, that increases gradually until 3mo after the venous occlusion onset, and then finally disappears after month 4th. The IOP increases lead to the ocular hypertension and glaucoma. The possible pathogenetic correlations between ocular hypertension/glaucoma and acute central/hemicentral RVOs have been classified into three groups: 1) the venous occlusion precedes the ocular hypertension/glaucoma causing neovascular glaucoma and secondary angle-closure glaucoma without rubeosis; 2) the ocular hypertension and the glaucoma precede the venous occlusion and favor its appearance (ocular hypertension, primary angle-closure, primary angle-closure glaucoma, and open angle glaucomas); and 3) the venous occlusion and the ocular hypertension/glaucoma are mostly age dependent appearances due to common vascular and collagen alterations, lacking a causal connection between the 2 conditions.

“…It has been proposed that in some cases of CRVO, vascular engorgement and edema of the posterior segment may result in anterior rotation of the cilio-lenticular diaphragm, thereby closing a previously narrow but open drainage angle. 11,12 However, it is also plausible that the profound pressure rises that occur in primary angle-closure (PAC) induce CRVO through a similar mechanism to that suggested in POAG. [1][2][3] Furthermore, since the first reports of angle-closure and RVO, 7,8 there have been limited additional data, with a more recent case series of 4 subjects with vascular accidents associated with angle-closure describing only 2 cases of APAC and CRVO.…”
