Macular pseudohole

A 63 years old lady systematically free presented with symptoms of floaters of her right eye minimally distorted vision BCVA in her left eye 20/25, and her vision in the left eye is 20/20.


Her left eye's clinical examination: anterior and posterior segment unremarkable while her right eye the anterior segment exam is unremarkable, her fundus exam shows some vitreous opacities and abnormal macular and irregular foveal reflex.


Fundus image


Fundus colored photograph shows wrinkling of the internal limiting membrane (ILM) and epiretinal formation with vascular tortuosity forming a cellophane maculopathy. However, the fovea has an abnormal shape with suspicion of a macular hole; some of the fundus' anatomical features are masked due to vitreous opacities.

Optical coherence tomography


OCT scan shows vitreomacular abnormalities in the form of an epiretinal membrane with minimal focal disturbance of inner retinal tissues with abnormal foveal contours with no disturbance of external limiting membrane nor ellipsoid zone, with a slight increase of retinal thickness.

The enface image in the Vitreous/ILM level shows an epiretinal membrane with a smooth central circle with a central hyporeflective circle presenting the epiretinal membrane's hole.

Diagnosis: Macular Pseudohole


Management: Follow up as BCVA is 20/25


Discussion


Epiretinal membrane forms when a schisis of the posterior cortical vitreous occurs in the PVD process, explaining the vitreous opacities. The remnant of the cortical vitreous will induce glial proliferation, which can cause tangential traction. In this case, there is no full-thickness retinal defect. Instead, a gap in the epiretinal membrane appears as a macular hole with thickened retinal tissue around the abnormally-shaped fovea. In contrast, the lamellar hole may or may not feature an epiretinal membrane with cleavage of inner retinal layers and foveal cavity with undermined edges with or without cystic changes with an irregular lamellar split of the outer retinal layers at the fovea or without intact ellipsoid zone. However, full-thickness macular hole, presented with a full-thickness foveal defect in the stages 2,3,4 and usually as the vitreomacular traction is the main pathological factor.


Clinically the pseudohole has better visual outcomes than the lamellar hole, but pseudohole can be transformed into a lamellar hole, and PPV indicated in cases with poor visual acuity

A full-thickness hole can be presented with poorer visual acuity and may require pars plana vitrectomy with ILM peeling.

Cellophane maculopathy

Caused by an epiretinal membrane, clinically, it appears as a sheen abnormal foveal reflex which features epiretinal membrane, due to inflammatory mediators and proliferation of glial cells secondary to a partial separation of posterior cortical vitreous. Fundus image shows cellophane maculopathy OCT features a hyperreflective band covering the inner retinal layers, causing minimal disturbance of inner retinal tissues. OCT cross-section shows epiretinal membrane  Cellophane maculopathy itself in individuals with good visual acuity may not need any interventions, but it is warranted to do a detailed peripheral retinal exam to rule out retinal tear or hole However, an epiretinal membrane may proliferate further and cause additional tangential traction. Thus, it may induce macular pucker or lamellar/pseudo hole and increase disturbance of inner retinal tissues, macular thickness, and reduction of vision. These patients may require pars plana vitrectomy to remove the epiretinal membran...

RPE tear, and it's OCT features in a nutshell

RPE tear can occur in vascularized PEDs due to a complication of intravitreal AntiVEGF treatment, which causes a rapid contraction of CNVm, inducing traction on the RPE surface and shrinking of RPE surface. On OCT, the RPE rip will indent the retina with increased hyperreflectivity in contracted RPE with underlying shadowing hinders choroidal view in contrast to the area where RPE where it ripped of which only Bruch's membrane is visible and increasing the visibility of the underlying choroid. RPE tear Thus two opposite forces, the regression of CNVm and remaining attached RPE, other causes such as laser or spontaneous can occur. However, the AntiVEGF treatment continued despite the RPE tear. Please check  Clinical guidelines for ARMD  and  course of clinical changes in RPE

Diabetic macular edema with ischemic changes associated with very severe NPDR

A 51 years old male known to be diabetic for ten years with excellent glycemic control profile along with normal blood pressure presented with BCVA 20/100 in his left eye; he had a better vision of 20/30 in the same eye one year ago when he used to be on intravitreal injections of aflibercept, but he decided to discontinue intravitreal injection as been advised by another physician. Fundus image His fundus image shows cystic formation at the fovea with a sign of intraretinal dot and blots hemorrhages in the mid periphery with cotton wool spots and IRMA (Intra Retinal Microvascular Abnormalities). Fundus image showing macular edema with intraretinal hemorrhage and cotton wool spots Optical coherence tomography His OCT scan shows thickened central macular tissues with disorganization of inner retinal layers and non-empty cystic formation as it is classic findings of diabetic macular edema with some empty cystic formation; however, the ellipsoid zone looks intact.
