Aim:
To evaluate flexible Ahmed glaucoma valve implant for selected cases of refractory glaucoma regarding its efficiency in controlling intraocular pressure and possible postoperative complications of its implantation and their management.
Method:
Patients included in this study were selected from patients with uncontrolled intraocular pressure by conventional filtration surgery as well al maximum tolerable topical medical treatment when surgery or laser is unlikely to control intraocular pressure. For every patient, complete history and ocular examination were done. Ahmed glaucoma valve flexible plate implant (FP7 and FP8) was used.
Results:
Intraucolarpressure decreased from a mean preoperative of (40.36 ± 4.8) mmHg with a range of 32 mmHg to 58 mmHg to a mean postoperative value of (18.73 ± 4.8) mmHg with a range from 14.0 mmHg 28.0 mmHg and the criteria of success were applied on 92.5% of eyes.
Conclusion:
Flexible Ahmed glaucoma valve plate implant is satisfactory method for controlling the elevated intraocular pressure in cases of refractory glaucoma with success rate 92.5% and less incidence of immediate postoperative and implant-related complications.
