Retinopathy of prematurity: Past, present and future

Figure 1 RetCam fundus images showing retinopathy of prematurity stages 1, 2, 3 and 4A. A: Fundus image of right eye showing stage 1 ROP with demarcation line (black arrows); B: Fundus image of right eye showing stage 2 ROP with ridge (black arrows); C: Fundus image of left eye showing stage 3 extra retinal fibrovascular proliferation (black arrows); D: Fundus picture of left eye showing stage 4A partial retinal detachment not involving the fovea (black arrows). Laser scars are shown with white arrows. ROP: Retinopathy of prematurity.

Figure 2 RetCam fundus images showing retinopathy of prematurity stages 4B, 5, plus disease and aggressive posterior-retinopathy of prematurity. A: Fundus picture of right eye showing stage 4B partial retinal detachment involving the fovea (black arrow). Optic disc is shown with a white arrow; B: Anterior segment picture of right eye showing stage 5 ROP with total retinal detachment (white arrow); C: Fundus picture of right eye showing dilated and tortuous vessels suggestive of plus disease; D: Fundus picture of left eye showing aggressive posterior ROP. ROP: Retinopathy of prematurity.

Figure 3 RetCam fundus images showing threshold, type 1, type 2 retinopathy of prematurity and post laser regressed retinopathy of prematurity. A: Fundus image of right eye showing “threshold ROP” (black arrows); B: Fundus image of right eye showing stage 3 ROP in zone 1 (black arrows) with plus disease suggestive of “type 1 ROP”; C: Fundus image of right eye showing stage 2 ROP in zone 2 (black arrows) without plus disease suggestive of “type 2 ROP”; D: Fundus picture of right eye showing laser scars (black arrows). ROP: Retinopathy of prematurity.
