Bruch Membrane
The inner layer of CHOROID, also called the lamina basalis choroideae, located adjacent to the RETINAL PIGMENT EPITHELIUM; (RPE) of the EYE. It is a membrane composed of the basement membranes of the choriocapillaris ENDOTHELIUM and that of the RPE. The membrane stops at the OPTIC NERVE, as does the RPE.
Iris
Pigment Epithelium of Eye
Lens Subluxation
Retina
The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.

Repopulation of different layers of host human Bruch's membrane by retinal pigment epithelial cell grafts. (1/198)
PURPOSE: To determine the morphology of human retinal pigment epithelium (RPE) after reattachment to different ultrastructural layers of human Bruch's membrane (BM). METHODS: Bruch's membrane explants were prepared from eyes of 23 human donors (age range, 11-89 years). The basal lamina of the RPE, inner collagenous layer, and elastin layer were removed sequentially by mechanical and enzymatic techniques. First-passage cells of human RPE (15,000 cells/6 mm explant) from three donors (ages, 52, 64, and 80 years) were plated onto different layers of human BM, and the explants were examined by scanning and transmission electron microscopy up to 21 days later. RESULTS: RPE flattened and extended footplates 6 hours after plating onto basal lamina. Cells remained round 6 and 24 hours after plating onto the inner collagenous, elastin, or outer collagenous layer. The RPE cells became confluent 14 days after plating onto basal lamina but did not become confluent up to 21 days after plating onto the inner collagenous or elastin layer. Sparse round cells were observed 21 days after plating onto deeper layers, suggesting extensive loss of RPE. CONCLUSIONS: The morphology and subsequent behavior of the RPE reattached to BM depends on the anatomic layer of BM available for cell reattachment. The results suggest that the ability of transplanted RPE to repopulate BM in age-related macular degeneration and other disorders may depend on the layer of BM available to serve as a substrate for cell reattachment. (+info)Increase in the advanced glycation end product pentosidine in Bruch's membrane with age. (2/198)
PURPOSE: To determine whether there is an age-related increase of pentosidine in human Bruch's membranes and to localize pentosidine and carboxymethyllysine (CML), two well-characterized, advanced glycation end products (AGEs) in aged human Bruch's membranes and choroid in vivo. METHODS: Human Bruch's membrane samples were isolated from the retinal pigment epithelium (RPE) and choroid and subjected to reversed-phase high-performance liquid chromatography to determine pentosidine content. A polyclonal anti-pentosidine antibody and a monoclonal antibody specific for carboxymethyllysine were used to localize AGEs in 20-month-old nondiabetic, 82-year-old nondiabetic, and 82-year-old diabetic globes. RESULTS: Human Bruch's membranes (n = 20) showed a linear age-dependent increase in pentosidine that reached approximately 0.17 millimoles pentosidine per mole hydroxyproline in late life (r = 0.896; P < 0.001). Immunohistochemical evaluation showed evidence of pentosidine in Bruch's membrane, choroidal extracellular matrix, and vessel walls in the 82-year-old nondiabetic and diabetic globes. A similar staining pattern was found with the anti-CML antibody. Basal laminar deposits and drusen stained with both antibodies in the elderly nondiabetic eye. In contrast, neither antibody stained the 20-month-old tissue. CONCLUSIONS: We provide biochemical and immunohistochemical evidence for the formation of pentosidine and CML structures in human Bruch's membrane and choroid with age. These changes could promote aging of the RPE-Bruch's membrane-choroid complex. (+info)Early drusen formation in the normal and aging eye and their relation to age related maculopathy: a clinicopathological study. (3/198)
AIM: To describe the early formation of drusen and their relation to normal aging changes at the macula and to the development of age related maculopathy (ARM). METHOD: Histopathological features of 353 eyes without histological evidence of ARM are described and correlated with the clinical appearance. In addition, 45 of these eyes were examined by transmission electron microscopy. RESULTS: Drusen were detected histopathologically in 177 (50%) eyes but were seen clinically in only 34% of these. Drusen were mainly small hard drusen with an occasional soft distinct drusen: no soft indistinct drusen were seen. Only those drusen deposits larger than 25-30 microns in diameter were detectable clinically. Preclinical drusen in eyes with only an occasional drusen were seen on electron microscopy as entrapment sites of coated membrane bound bodies which formed adjacent to the inner collagenous zone of Bruch's membrane. In contrast, preclinical drusen deposits in eyes with many drusen were seen as accumulations of amorphous material which appeared hyalinised by light microscopy. A distinct feature were rows of dense hyalinised microdrusen (1-2 microns in diameter), over which larger globular hyalinised drusen formed. CONCLUSION: Histological and ultrastructural examination can recognise and distinguish the earliest drusen formed as a result of normal aging from those associated with ARM. In eyes without diffuse deposits, histologically all drusen were of the hard hyalinised variety or their derivatives; no soft drusen composed of membranous debris were found. These findings support and explain those of other authors who do not consider the presence of a few small hard drusen to be a risk factor for the development of ARM. (+info)Development of a polyclonal antibody with broad epitope specificity for advanced glycation endproducts and localization of these epitopes in Bruch's membrane of the aging eye. (4/198)
PURPOSE: To develop an antibody that recognizes a variety of advanced glycation endproduct (AGE) epitopes. METHODS: Glycolaldehyde was used to modify bovine serum albumin and HPLC analysis was used to measure pentosidine formation as an indicator of AGE formation. A polyclonal anti-AGE antibody was synthesized by injecting glycolaldehyde-incubated keyhole limpet hemocyanin into rabbits, affinity purified using AGE modified bovine serum albumin coupled to an affinity resin column, and characterized by immunoblot analysis. RESULTS: HPLC analysis of glycolaldehyde treated bovine serum albumin detected high levels of pentosidine formation, suggesting that glycolaldehyde is a potent precursor for pentosidine. By immunoblot analysis, our antibody recognized carboxymethyllysine and pentosidine, two well-characterized AGEs, as well as other AGE epitopes. Immunohistochemical evaluation showed evidence of AGEs in Bruch's membrane (including basal laminar deposits and drusen), choroidal extracellular matrix, and vessel walls in an 82 year old nondiabetic globe. A similar staining pattern was observed in an age-matched diabetic control. In contrast, no staining was seen with the antibody in a 20 month old nondiabetic globe. CONCLUSIONS: A unique anti-AGE antibody was synthesized that recognizes a variety of AGE epitopes including carboxymethyllysine and pentosidine. Its best use might be in broad surveys of the age-dependent accumulation of a large number of AGE epitopes that might not be revealed by antibodies to pentosidine or CML. (+info)TIMP-3 in Bruch's membrane: changes during aging and in age-related macular degeneration. (5/198)
PURPOSE: To assess the distribution, content, and function of tissue inhibitor of metalloproteinases (TIMP)-3 during aging in normal eyes for comparison with the levels observed in eyes with age-related macular degeneration (AMD). METHODS: Donor tissues analyzed included 36 normal eyes (14-96 years old) and 15 AMD eyes (74 -98 years old). A tissue strip including the fovea was used for immunohistochemistry. Western blot analysis was performed on extracts of the retinal pigment epithelium (RPE)- choroid complex from the posterior part of each eye. Immunoreactivity of TIMP-3 bands in each western blot was densitometrically quantitated. The inhibitory function of TIMP-3 was evaluated with reverse zymography. RESULTS: TIMP-3 was present uniformly across Bruch's membrane in the normal samples. In samples from donors more than 50 years of age, immunostaining was intense. TIMP-3 content ranged from 92 to 1061 ng/cm2 and increased with age (r = 0.66). In AMD eyes, TIMP-3 distribution in Bruch's membrane was abundant in areas of continuous soft drusen but absent in areas below RPE atrophy. TIMP-3 levels in AMD eyes were significantly higher than in age-matched normal eyes (577 versus 877 ng/cm2; P = 0.009). Inhibitory activity correlated well with TIMP-3 content (r = 0.82) and was also significantly higher in AMD eyes than in age-matched normal eyes (P < 0.001). CONCLUSIONS: During normal aging, TIMP-3 content in Bruch's membrane of the macula shows a significant increase. TIMP-3 content in AMD eyes was elevated relative to that of age-matched normal eyes. Higher levels of TIMP-3 may contribute to the thickening of Bruch's membrane observed in AMD. (+info)Age-dependent variation in metalloproteinase activity of isolated human Bruch's membrane and choroid. (6/198)
PURPOSE: To characterize and determine the effect of aging on the matrix metalloproteinase (MMP) component of the extracellular matrix-remodeling mechanism of isolated human Bruch's-choroid. METHODS: Immunohistochemical techniques and western blot analysis were used to detect and localize various members of the MMP family of proteolytic enzymes in the Bruch's-choroid complex. Gelatin substrate zymography was used to detect and quantify the levels of MMP-2 and -9 in homogenates of Bruch's-choroid from both macular and peripheral regions of the human fundus. Aging alterations in these enzymes were quantified by densitometric analysis of photographic negatives of the zymography gels. RESULTS: Intact preparations of Bruch's-choroid showed the presence of inactive forms of two gelatinases (MMP-2, 65 kDa, and MMP-9, 92 kDa), interstitial collagenase (MMP-1, 52 kDa) and stromelysin (MMP-3, 57 kDa). MMP-1 and -3 were localized primarily to Bruch's membrane. MMP-9 was distributed evenly in Bruch's membrane with some patchy presence in the choroidal mass. Distribution of MMP-2 was similar to that of MMP-9, but the staining in Bruch's was much fainter. On gelatin zymography, an active form of MMP-2 (58-kDa species) was frequently observed in peripheral samples but only occasionally in macular regions. The levels of MMP-2 and -9 increased with aging in both the macular and the peripheral regions of the fundus (P < 0.05). MMP-2 levels were lower in macular regions than in the periphery but no such variation was observed with MMP-9. Both these inactive gelatinases could be activated in vitro. CONCLUSIONS: A matrix-degrading mechanism essential for extracellular remodeling was shown to be present in Bruch's membrane. In macular regions, increasing levels of inactive forms of metalloproteinase and scarcity of active forms of MMP-2 suggests possible involvement of impaired extracellular degradation in both aging and macular degeneration. (+info)Ultrastructural changes in Bruch's membrane of apolipoprotein E-deficient mice. (7/198)
PURPOSE: To examine the histologic and ultrastructural changes in Bruch's membrane (BM) in apolipoprotein E deficient [ApoE(-)] mice in comparison with age-matched control animals. METHODS: Two-month-old (group 1) and 8-month-old (group 2) normal control C57BL/6 mice and 2-month-old (group 3) and 8-month-old (group 4) ApoE(-) mice were studied. All groups of mice were fed a standard rodent diet. The mice were killed, serum lipid levels were determined, and the eyes were ultrastructurally examined using standard techniques to measure the thickness of BM. The area fraction of electron-lucent (EL) particles in BM was quantified using point-counting stereology. RESULTS: The serum cholesterol levels of the ApoE(-) mice were significantly higher than those of the control mice (P = 0.0001). There was a significant thickening and EL particle accumulation in BM associated with age in the control animals. Group 2 had a thicker BM and more EL particle accumulation than group 1 (P = 0.0410 for thickness; P = 0.0042 for particle accumulation). Age-related changes were not seen in ApoE(-) mice; thickness and accumulation were similar in groups 3 and 4 (P = 0.50, thickness; P approximately/= 1.0, accumulation). Significant thickening and accumulation were seen in young ApoE(-) mice (group 3) versus young control animals (group 1; P = 0.008, thickening; P < 0.0001, EL particle accumulation). Group 4 ApoE(-) mice did not have a thicker BM or more EL particles than group 2 control animals (P = 0.2910, thickness; P = 0.35, EL particle accumulation). "Membrane-bounded" material (material between two membranes) was present significantly more frequently in ApoE(-) mice. CONCLUSIONS: ApoE(-) mice exhibit accumulation of EL particles at an earlier age and have more membrane-bounded material in BM than control mice. This material has ultrastructural similarities to basal linear deposit, which accumulates in age-related maculopathy. (+info)Age-related retinal pigment epithelium and Bruch's membrane degeneration in senescence-accelerated mouse. (8/198)
PURPOSE: To investigate age-related changes in the retinal pigment epithelium (RPE), Bruch's membrane, and choriocapillaris in the senescence-accelerated mouse (SAM). METHODS: The external and eyecup features and light and electron microscopic findings were examined in three male and two female mice of a senescence-prone mouse strain (SAM P(8)) monthly for 12 months. These results were compared with those in age-matched mice of similar background but senescence resistant (SAM R(1)). Choroidal vascular casts were prepared at 12 months in seven mice each of the SAM P(8) and SAM R(1) strains. Quantitative analysis of area of choriocapillaris was performed by automated image analysis, and the results were analyzed by paired Student's t-test. RESULTS: We found in the SAM P(8) strain that hair loss, coarseness of hair texture, and ulceration of skin appeared and increased as the age advanced (at approximately 5-9 months). Eyecup examination showed no differences. Light and electron microscopy revealed progressively more prominent abnormalities in the RPE and Bruch's membrane mice older than 10 months. Two of the five SAM P(8) mice older than 11 months showed what appeared to be intra-Bruch's membrane choroidal neovascularization. The RPE and Bruch's membrane appeared normal in the SAM R(1) strain. In the SAM P(8), vascular casts of the choriocapillaris showed a mild but significant decrease in vascular area when compared with the SAM R(1) strain at 12 months (P = 0.011). CONCLUSIONS: Senescence accelerated mice develop progressive age-related changes in the RPE-Bruch's-choriocapillaris complex that have features that may be relevant in the study of age-related macular changes in humans.
