The human retina is composed of functionally and molecularly distinct regions, including the fovea, macula, and peripheral retina. Here, we describe a method using punch biopsies and manual removal of tissue layers from a human eye to dissect and collect these distinct retinal regions for downstream proteomic analysis.

This video demonstrates the development of an ex vivo model of choroidal sprouting to study ocular microvascular angiogenesis. The assay involves culturing mouse eye explants containing the choroid tissue attached to the sclera and retinal pigment epithelium under specific conditions that promote choroidal microvascular sprouting.

This video presentation shows a method of harvesting the two most important highly vascular structures that support forebrain function. They are the cerebral surface (superficial) vasculature along with associated meninges (MAV) and the choroid plexus which are necessary for cerebral blood flow and cerebrospinal fluid (CSF) homeostasis.

FAQs
Natural interfaces provide separation planes between the eye’s tissue layers, helping the operator peel them apart under magnification rather than disrupting the surrounding structures. Following these planes supports cleaner isolation of the fibrous sclera, vascular choroid, and pigmented retinal pigment epithelium. Preserving the interfaces as much as possible improves the reliability of later layer-specific structural and molecular comparisons.
Each layer contains different cellular and tissue features, so contamination can make molecular or histological findings difficult to assign confidently. Careful separation reduces the chance that material from the sclera, choroid, or retinal pigment epithelium will be mistakenly interpreted as originating from another layer. This distinction is particularly important when relating tissue changes to retinal or choroidal disease.
The sclera is characterized as a fibrous outer tissue, the choroid as a vascular layer, and the retinal pigment epithelium as a pigmented retinal-associated layer. These differences provide anatomical landmarks during microscopic separation and later analysis. Recognizing the identity of each layer allows investigators to connect observed structural or molecular changes with the appropriate ocular compartment.
Layer-specific analysis separates changes associated with the eye’s supporting, vascular, and retinal-associated compartments. This enables researchers to examine whether findings are localized or shared across tissues instead of treating the eye as a single undifferentiated sample. The approach therefore helps relate ocular pathology to visual processing, neurodegeneration, inflammation, and the progression of retinal or choroidal disorders.
The workflow uses magnification to open the ocular tissue and then carefully peel the layers apart along their natural interfaces. The operator aims to isolate the sclera, choroid, and retinal pigment epithelium while limiting tissue damage and transfer between samples. Once separated, the layer-specific material can be directed toward structural or molecular analysis.
The separated samples support histological examination as well as gene and protein analysis. Histology can reveal layer-specific structural features, while molecular assays can assess differences in gene or protein content between the sclera, choroid, and retinal pigment epithelium. Using these approaches together provides complementary evidence about tissue organization and disease-associated changes.
Researchers can use the technique when they need to investigate how changes are distributed among the sclera, choroid, and retinal pigment epithelium. It is relevant to studies of retinal and choroidal disorders, inflammation, neurodegeneration, visual processing, and disease progression. Separating the compartments helps connect a pathological observation with the specific ocular layer in which it occurs.
Compartment-specific samples allow investigators to compare structural, gene-level, or protein-level changes across the three ocular layers. These comparisons can clarify whether disease-related alterations are concentrated in a vascular, fibrous, or retinal pigment-associated compartment. Such localization strengthens interpretation of mechanisms underlying retinal and choroidal disorders and supports more precise links between ocular pathology and neuroscience.
