Angle-recession glaucoma, being a consequence of blunt injury of an eyeball, is likely to develop in both a short or very distant period. The likelihood of the incidence of that condition in the clinical form is determined by the extent of injuries of ciliary cleft structures, especially of a trabecular meshwork. The manuscript reports a case of an early glaucoma secondary to a blunt injury of an eyeball with symptoms of angle recession to 300 degrees of periphery and intraocular pressure (IOP) at a level of 62 mmHg. The basic diagnostic examination that enables the evaluation of an angle, iris root and an opening to the ciliary cleft is gonioscopy. In case of a lack of response to the pharmacological reduction of IOP, a method of choice still remains a surgical procedure. In the reported case, a drainage procedure was applied in the form of implantation of the Ahmed valve prosthesis. Control tonometric examinations of the operated eye, performed over a 20-week period of postoperative management, demonstrated IOP at a level of 19 mmHg.
