Pseudophakic cystoid macular edema associated with extrafoveal vitreoretinal traction.

Martinez MR, Ophir A - Open Ophthalmol J (2011)

Bottom Line: Excluded were eyes that either had another vitreoretinopathy that could affect the analysis or had undergone an intravitreal intervention.Three eyes (three patients) with macular edema following uneventful cataract surgery were detected to be associated with multifocal extrafoveal vitreoretinal traction sites in each.Retinal edema that was underlying each of the traction sites in all eyes was in continuum in at least one site per eye with the central macular edema, thus manifesting as diffuse macular edema.

ABSTRACT

Purpose: To describe an association between extrafoveal vitreoretinal traction and intractable chronic pseudophakic cystoid macular edema (CME) by the use of optical coherence tomography (OCT).

Methods: In a retrospective case series study, charts and OCT findings of patients who had postoperative recalcitrant pseudophakic CME for at least 6 months and vitreoretinal traction membranes were analyzed. Excluded were eyes that either had another vitreoretinopathy that could affect the analysis or had undergone an intravitreal intervention.

Results: Three eyes (three patients) with macular edema following uneventful cataract surgery were detected to be associated with multifocal extrafoveal vitreoretinal traction sites in each. Retinal edema that was underlying each of the traction sites in all eyes was in continuum in at least one site per eye with the central macular edema, thus manifesting as diffuse macular edema.

Conclusion: Chronic pseudophakic macular edema may be related to extrafoveal vitreoretinal traction.

Extrafoveal multifocal vitreoretinal traction associated with pseudophakic CME as detected by a time-domain OCT (Pt. 3). (A) Vitreous traction membrane (asterix) located at the papillomacular bundle area, in proximity to the ONH (not shown). An underlying localized subretinal fluid (star) and a diffuse macular edema are associated with the traction membrane. (B) A second vitreoretinal traction membrane (arrowhead) is located temporo-superiorly to the fovea; a retinal edema underlies it. (C) The 6-mm false-color and quantitative thickness macular maps disclose diffuse macular edema associated with two different tractions sites (marked by arrowhead and asterix). The central sub-field thickness is 370 µm. (D) The quantitative macular map of the normal controls (n = 12).

Mentions: The third eye (No. 3) was examined by TD-OCT (OCT-2000) and presented with diffuse macular edema accompanied by cystoid spaces. Vitreoretinal traction membranes were identified at two sites, one parafoveally at the papillomacular bundle (PMB) zone and the second temporally to the fovea (Fig. 3; a 3-D image reconstruction is not available in the TD-OCT). The centrally fixated Automatic 6-radial lines program of the OCT-2000 enabled the diagnosis of extrafoveal vitreous traction, which was located parafoveally at the PMB site. A small area of subretinal fluid underlined this traction site. The second traction site in this eye was detected by the Line group program, but not by the Automatic 6-radial lines program. The retinal edema that underlined each of the two detected traction sites was in direct communication with the edema at the central macula. This observation could be depicted from the OCT B-mode and the macular map (Fig. 3C, D).
