Serous PED Case report and Discussion

A 78 years old lady pseudophakic presented to me with reduced vision. Her BCVA is Hand motion in her Right eye, while in her left eye, the BCVA is 20/40 fundus examination showed drusen and signs of dry, moderate ARMD.


Clinical examination shows a smooth, well-defined border of RPE elevation and a slight pale appearance accompanied by subretinal fluid and exudation, along with drusen and subretinal scar.


Optical coherence tomography 


OCT features smooth RPE elevations, which contains clear fluids that look like a homogeneous hyporeflective area with subretinal fluids accompanied by ellipsoid zone disruption and intraretinal cysts.

Diagnosis: 

This is a case of neovascular advanced ARMD with serous pigment epithelial detachment


Management


This patient managed with monthly intravitreal Aflibercept for three consecutive injections. Post-treatment OCT cross-section shows resolving both subretinal fluid and serous PED and improved vision to counting fingers patient was followed up using PRN protocol.


Discussion


Wet ARMD can present as serous pigment epithelial detachment, which features a fluid leak via Bruch’s membrane to space between Bruch’s and RPE, causing increased hydrostatic pressure separating RPE from Bruch’s membrane, causing disturbance of outer retinal tissue such as ellipsoid zone and scar formation.


Treating serous PED is a clinical challenge with poor prognosis; however, better treatment response to VEGF trap (Aflibercept or Conbercept) in contrast to Anti VEGF (Bevacizumab or Ranibizumab).


This case was treated with intravitreal Aflibercept for three consecutive monthly injections. Post-treatment OCT shows improvement in terms of PED, showing that both subretinal fluid and serous PED with BCVA improved to counting fingers and not better due to disturbed ellipsoid zone and subretinal scar.


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

  1. You are doing a great job by writing such informative article. Interesting at the same time. Also check this out Eye Exam San Diego. Thank you.

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
