Pathogenesis of tears of the retinal pigment epithelium

This report confirms a previous report that elderly patients with serous detachments of the pigment epithelium prior to and after developing a pigment epithelial tear at one border present a characteristic ophthalmoscopic and fluorescein angiographic appearance. Evidence is presented that subpigment epithelial choroidal neovascularisation and not irregular separation of the basement membrane from its pigment epithelium is the primary cause of the detachment and tear in the pigment epithelium.
Bilateral tears of the retinal pigment epithelium
British Journal of Ophthalmology, 1988
This paper describes bilateral tears of the retinal pigment epithelium (RPE) which followed photocoagulation treatment of retinal pigment epithelial detachment (PED) in the right eye and which occurred spontaneously in the left eye. A 66-year-old Japanese male presented with PED approximately 4x 6 disc diameters in size in his right eye, and one disc diameter in the left eye, both in the macular regions. The right PED was treated by placing a row of argon laser photocoagulation along the margin of the PED, with avoidance of the papillomacular bundle. Five days after treatment the PED enlarged peripherally beyond the coagulated site. Nineteen days later an RPE tear developed at the temporal edge of the detachment in the right eye. The remaining detached RPE retracted centrally, forming curled folds. About 40 days after the initial examination the patient complained of sudden reduction of vision in his left eye. At this time an enlargement of the PED was found in his left eye. One week after this examination a small RPE tear was found in the nasal border of the PED in the left eye. The tear in the left eye gradually developed centrally to the fovea.
Tears of detached retinal pigment epithelium
British Journal of Ophthalmology, 1981
Ripping of detached pigment epithelium appears to be a common sight-threatening complication of pigment epithelial detachments and occurs at the junction of the detachment and flat pigment epithelium. The characteristics of the detachment prior to the rip suggest that the tear occurs in pigment epithelium which is detached without its basement membrane. The tear is followed by retraction of the pigment epithelium, revealing bare Bruch's membrane. The defect may remain apparently unaltered, or may be recovered by normal looking pigment epithelium, but most commonly is replaced by a fibrous plaque. Most patients had a profound reduction in visual acuity.
Retinal Pigment Epithelium Tears in Younger Patients: Causes and Consequences
Acta Medica Medianae, 2020
We present three different cases of patients with retinal pigment epithelium (RPE) tear: one case with choroidal osteoma, one with central serous chorioretinopathy (CSHR) and one with idiopathic polypoidal vasculopathy (IPCV). Fotodocumentation, fluorescein angiography, optical coherence tomography (OCT) and OCT angiography showed typical choroidal neovascularization in patient with osteoma and IPCV. In patient with CSHR, large PED without choroidal neovascularization was present. PED tear was detected in all patients. Various eye disorders, such as tear of retinal pigment layer, can complicate clinical picture and be associated with PED. Large height and diameter of PED, association with CNV, small ratio of CNV size to PED size, lines in infrared images, and duration of PED may predict the course of RPE tear. Therefore, it should be monitored for this complication. Treatment and outcome depends on cause of tear.
Retinal Cases & Brief Reports, 2018
Purpose: To report a patient presenting a retinal pigment epithelial tear in which optical coherence tomography angiography enabled the visualization of subfoveal choroidal neovascularization (CNV) not evidenced by the fluorescein angiography. She was treated with 3 monthly intravitreous anti-VEGF injections and intraretinal fluid resolution occurred. Methods: Observational case report. Results: A 62-year-old Caucasian woman presented with decreased visual acuity in the right eye for 3 months. Fundus biomicroscopy revealed a yellowish macular lesion associated with intraretinal hemorrhage. Fluorescein angiography showed a large hyperfluorescent area consistent with window defect. Optical coherence tomography showed a retinal pigment epithelial tear with subretinal fluid. However, there was no clear evidence of CNV on fluorescein angiography or OCT. Optical coherence tomography angiography confirmed the presence of an active CNV by the visualization of the neovascular network in the region corresponding to the scrolled up retinal pigment epithelium. Conclusion: This case report demonstrates that optical coherence tomography angiography can be useful to confirm the presence of CNV in cases where fluorescein angiography and OCT cannot establish the diagnosis. The reported case suggests the applicability of optical coherence tomography angiography in patients in whom retinal pigment epithelial tear is detected and associated CNV is suspected.
Journal of Cataract and Refractive Surgery Online Case Reports, 2014
A 66-year-old man was referred to our clinic with decreased vision in the left eye. Nine days earlier, the patient had had uneventful phacoemulsification with intraocular lens (IOL) implantation in the left eye. The preoperative examination showed a cortical nuclear cataract and a normal fundus. One day post surgery, visual acuity in the left eye had deteriorated, and at the time of referral, the corrected distance visual acuity was 20/160. Fundus biomicroscopy and optical coherence tomography showed a retinal pigment epithelial tear with subretinal fluid collection involving the macula. Fluorescein angiography showed no choroidal neovascularization on the macula. We report a case of retinal pigment epithelial tear after uneventful phacoemulsification with posterior chamber IOL implantation in an eye that was normal except for the presence of an immature cataract.
