RPE atrophy post-laser treatment discussion

This case is an example of RPE atrophy induced by focal laser photocoagulation.


Fundus Image


Fundus exam showed non-proliferative diabetic retinopathy along with hard exudates, central diabetic macular edema, intraretinal blood, and patches of RPE atrophy as a result of previous laser treatment.

Optical coherence tomography

OCT scan shows increased central retinal thickness, with the cystic formation in the inner retinal tissues with hyperreflective foci presenting hard exudates and RPE atrophy induced by laser photocoagulation treatment.

Discussion

This patient has good BCVA 20/32 despite RPE atrophy's presence because of its location away from FAZ.


This patient was managed as central DME with monthly intravitreal injection of AntiVEGF.

Please check clinical guidelines in diabetic retinopathy

Von Hippel-Lindau

Von Hippel-Lindau in a young female, BCVA, is CF in her left eye. Findings are normal, and BCVA is 20/20. Drop a comment below 👇 telling how would you approach and manage this case ?! I would perform intravitreal AntiVEGF combined with laser treatment. Fundus image showing Von Hipple-Lindau

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...

Adult-onset vitelliform macular dystrophy

One of the most common pattern dystrophies similar to best occurs in adulthood, as it appears as oval or yellowish macular material, originated from the debris of photoreceptors, or the RPE phagocytosis failure. Fundus image showing Adult-onset vitelliform macular dystrophy  On OCT, it appears as subretinal vitelliform material accumulation but above the RPE with intact ellipsoid zone and thus explains good visual acuity without an increase in retinal thickness. OCT cross-section showing Adult-onset vitelliform macular dystrophy Fluorescein angiography typically shows hypo-fluorescence at the area of vitelliform accumulation surrounded with hyper-fluorescence increases intensity in late phases; however, it may show liner, patchy, or ring-like, which is inconsistent with visual acuity. Adult-onset vitelliform macular dystrophy itself does not warrant any treatment; however, a regular follow up to monitor any progression to choroidal neovascularization. How would you approa...
