Non-central CNV with central CME case report

Eighty-one years old phakic, his right eye has a subretinal disciform scar with hand motion vision, complains of sudden reduction of vision of his left eye to 20/50.

Clinical examinations show cystoid macular edema with subretinal fluids, off-center subretinal mass formation, and RPE alternation.

Optical coherence tomography

OCT cross-section shows thinning of the choroid with RPE alternation and non-central subretinal amorphous material resembling choroidal neovascular membrane with subretinal fluids and cystoid changes in the outer retinal tissues in the center of the macula.

The upper OCT cross-section shows subretinal hyper reflective material with subretinal and intraretinal fluids the other post treatment cross-section shows resolution of subretinal and intraretinal fluids with subretinal hyper reflective material reducing in size leaving small scar

Management

The patient managed three consecutive intravitreal injections of Aflibercept monthly, which successfully improved vision to 20/25.

OCT shows resolved macular edema, subretinal fluid and reduced the neovascular membrane's size, leaving a small non-central subretinal scar with an intact ellipsoid zone centrally.

Discussion

The subretinal choroidal neovascular membrane can severely damage the ellipsoid zone and cause permeant visual loss, even after treatment.

Another independent factor for reducing vision is an intraretinal cystic formation, which holds a bad prognosis.

This patient was treated promptly, which helped reduce both the injury to the central ellipsoid zone and intraretinal tissues.

Vision restored as treatment held the progression of the non-central choroidal neovascular membrane to central.

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 membrane an

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

Sectoral retinitis pigmentosa

Sectoral retinitis pigmentosa is an autosomal dominant and usually associated with acceptable visual acuity. The fundus examination shows pigment clumps and chorioretinal atrophy only in sectoral with almost normal optic disc configuration and vessel diameter. Fundus image showing Sectoral retinitis pigmentosa The sectoral retinitis pigmentosa symmetrical in both eyes Perimetry will show scotoma corresponding to the dispersion of pigmentary clumps. OCT shows outer retinal degeneration and RPE thining in the area of pigmentary clumps. Please check Clinical guidelines in retinitis pigmentosa
