Fibrovascular PED Case report and Discussion

An 81 years old man pseudophakic presented to me with features of ARMD; his BCVA is 20/200 in his Right eye, while in his left eye, the BCVA is 20/35; fundus examination showed drusen and signs of ARMD.

Fundus image

Fundus examination shows drusen, RPE elevation, and subretinal fluid.

Fundus image shows fibrovascular PED with reticular pseudodrusen

Optical coherence tomography

OCT cross-sections show RPE detachment area induced by a fibrovascular membrane with pronounced Bruch’s membrane forming double layered sign and subretinal fluid along of disturbed ellipsoid zone.

The upper OCT cross-section shows fibrovascular PED with subretinal fluids the lower OCT cross-section shows decreased size of PED and resolved subretinal fluid four months post treatment with monthly AntiVEGF

Diagnosis: This is a case of wet ARMD with occult choroidal neovascularization.

Management: This patient managed with monthly intravitreal Aflibercept for three consecutive injections and one-month post-treatment OCT cross-section shows resolving both subretinal fluid and fibrovascular PED and improved vision to 20/50, and the patient was followed up using PRN protocol.

Discussion

Wet ARMD can present as occult Choroidal neovascularization, which features a vascular proliferation sub RPE, and this proliferation may detach the RPE and induce PED and subretinal fluid, causing disturbance of outer retinal layers (ellipsoid zone),

Subretinal fluid and occult choroidal CNVm have a better visual prognosis than classical choroidal neovascularization, and intraretinal cyst may have a worse prognosis due to subretinal scar formation and intraretinal tissue disorganization.

This case treated with intravitreal Aflibercept for three consecutive monthly injections and one-month post-treatment OCT shows improvement in PED regression showing regression of the fibrovascular membrane and reducing in size and resolved subretinal fluid with BCVA improved to 20/50 and not better due to the disturbed ellipsoid zone.

Please tell me how you would manage this case in your clinical practice??!!!

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
