Purpose: To obtain and research sample of anterior chamber angle in child in different gestational age in normal and congenital glaucoma; to investigate the pieces of tissues removed during sinus trabeculectomy in babies with glaucoma, which were burned in different gestational age. Materials and Methods: Histology of anterior chamber angle was performed in five enucleated eyes; intravital investigation of trabecular meshwork was made in two cases of mature babies and one case of premature baby. Results: Histology of enucleated globes shows the main structures of anterior chamber angle: cornea, Descemet`s membrane, trabecular meshwork, Schlemm’s canal, iris. The morphology of anterior chamber angle in congenital glaucoma has some features: anterior chamber angle is blocked with permanent fibrous membrane, which penetrates in trabecular meshwork. Trabecular meshwork consist of thickened and rough tissue. Histology of fetal eyes in different gestational age shows obvious open anterior chamber angle, trabecular meshwork is cellular and well developed, fragmentation of Descemet`s membrane near the trabecular meshwork. There was no any signs of fibrous. There were no histological signs of fibrosing of the trabeculae. Conclusion: Intravital investigation of trabecular meshwork has some features and depends on the gestational age in birth. In mature babies with congenital glaucoma is the hypoplasia of trabecular meshwork, which covered with the rough fibrous membrane in some places and it is coincide with histology of enucleated globes. In premature babies the trabecular meshwork is fibrous and appear after the birth of premature baby, what is caused by the proliferation in such babies.
