1988;105:285–290.

26. Clinical features
•Abrupt sudden onset loss of vision
•Clinically, a well demarcated area of bare choroid visible
adjacent to hyperpigmented area, which is retracted,
redundant retina
•Temporal edge of PED most commonly affected

secondary to AMD. Graefes Arch Clin Exp Ophthalmol 2007; 245:1037–40.

27. Clinical features
•Often accompanied by subretinal hemorrhages, exudation
or break through vitreous hemorrhage
•Initial course, good prognosis
•Long term follow up- progressive visual loss
•Depends of foveal involvement
•Foveal involvement incidence range 23-75%

28. FFA,ICG and OCT
•FFA- Hyperfluorescence in area of bare choroid and
hypofluorescence in area of retracted and elevated RPE flap
•No leak in area of bare choroid-Atrophy of choriocapillaris
•ICG- Normal choroidal fluorescence in area of bare choroid and
varying degrees of hyperfluorescence in area of retracted RPE

tears in age-related macular degeneration. Am J Ophthalmol 1997;123:377–385.

•Interruption of hyperreflective RPE layer with elevated or
scrolled edge of torn RPE flap
•Three configurations of retracted RPE-
Dome shaped
Pleated
Tented
•Increased reflectivity in area of bare choroid

pigment epithelial tear. Retina 2000;20:37–40.

30. How does RPE Tear occur

31. Theories proposed
•Increased intra PED
hydrostatic pressure due to
enlargement
•Tangential forces on
posterior surface of detached
RPE
Gass JD (1984) Pathogenesis of tears of the retinal pigment epithelium. Br J Ophthalmol 68:513–519

32. Grading of RPE tear

33. •RPE tears grading based on the greatest length in the
vector direction of the tear and involvement of the fovea
using FA analysis

epithelial tears. Retina 2010;30(7):1039-1045.

34. Risk factors

35. •Fibrovascular PED > Serosanguinous PED> Serous
•Height of PED
•Greatest linear dimension of PED
•A Prospective study:
•Incidence of RPE tear -14%
•RPE tear + PED height >550μ-31%
•RPE tear + PED height > 550μ + ring sign on FFA/Grade 1 tear-
67%
•Hyperreflective linear lines on Near Infrared Imaging

epithelium detachment. Acta Ophthalmol 2014;92:e50–56.

37. What to be done if we have
significant risk factors

38. PED height >400 µm
Presence of hyperreflective lines in NIR images
Pause anti- VEGF therapy
Re-evaluate the lesion in 1–2 weeks
Look for contraction of CNV membrane that has
relaxed to some extent and to re-inject again.

epithelium detachment. Acta Ophthalmol 2014;92:e50–56.

39. Why it is more common in AMD
compared to PCV?

40. AMD v/s PCV
•More common in AMD – 3.5 % v/s 0.62% in PCV
•Pathogenesis differs
•Element of FVPED in AMD
–Anti VEGF causes fibrotic contraction ripping overlying RPE
•Large serosanguinous PED in PCV
–Vascular complexes in PCV may not contract enough
–AntiVEGF reduces leakage, but shrinkage of polypoidal
dilatations hardly affected.
–Adhesions of PCV components to RPE might be weak
–Micro rips (7.1%) at margin of PED reduces intra PED
pressure and thereby frank RPE tear

41. Does Anti-VEGF predisposes to
RPE tear

42. RPE tear post anti VEGF injections
•Bevacizumab, Ranibizumab, Pegabtinib, Aflibercept
•Overall incidence 5-19.7%
•Average number of injections before RPE tear 1.3
•Duration of appearance
•Earliest 1st day postoperative in our patient (Unpublished
data)
•Literature 11 days after initial injection (Range 11 days
to 46.3 weeks)*

44. FATE OF RPE TEAR

45. Repair mechanism
•Within 24 hours, the area where the RPE is absent
becomes covered by hypopigmented RPE cells
•Persistent SRF after an RPE tear may lead to
subsequent repair with thickened proliferative tissue at
the area where the RPE was lost
•Early resolution of the SRF after the RPE tear, the
•outer retina appeared to be directly attached to Bruch
membrane.

46. •Persistent SRF and active CNV may result in the horizontal
proliferation of the CNV membranes along Bruch membrane
within the SRF at the area where the RPE was lost.
•Weak leakage from inactive CNV may result in a rapid
resolution of the SRF. In addition, inactive CNV may not cause
any pooling of the SRF or cause any growth horizontally at the
area where the RPE disappeared. As a result, this may lead to the
attachment of the outer retina to Bruch membrane
•An ingrowth of a faintly opaque tissue layer into the area of the
tear, which gave the appearance of blunting of the edges of the
tear.

49. Should we continue Anti VEGF Rx in
patients with RPE tear?

52. •Chan et al reported continued improvement in visual acuity in
67% eyes treated with bevacizumab/ranibizumab after developing
RPE tear
•Gamulescu et al reported mean BCVA to be stable at 12 months
in eyes that received additional anti VEGF treatment
•Continuing anti VEGF Rx may reduce possible fibrotic ingrowth
replacing RPE tear

visual prognosis

associated with stabilisation of visual acuity and even
improvement

56. Take home message
• RPE tear are more common in patients with FVPED
• Increased incidence in anti VEGF era
• Baseline OCT measurements of height & GLD of FVPED
for subsequent follow ups-explain visual prognosis
• Look for hyperreflective lines on NIR imaging-If present,
wait for 2 weeks before injecting anti VEGF
• If RPE tear develops, have early follow ups to look for
progression
• Explain further course of the disease to the patient
• If persistent exudative changes noted with RPE tear, do
not hesitate to inject further anti VEGF injections
