Dr. Hazem Helmy is one of the leading pioneers of Ophthalmology in Egypt and the Arab world, and a professor, researcher and consultant at the Research Institute of eye diseases. Dr. Hazem Helmy has a PhD in ophthalmology and is currently the head of the Department of glaucoma and optic nerve surgery at the Research Institute of eye diseases.
Numerous studies have addressed the genetic and biochemical risk factors associated with glaucoma, especially closed-angle glaucoma and congenital glaucoma, in addition to evaluating modern surgical techniques for its treatment such as microscopic surgery and laser techniques.
Research on oxidative stress indicators in eye fluids and blood and their impact on the development of eye diseases such as glaucoma and diabetic retinopathy.
Studies on advanced surgeries such as combining different techniques for the treatment of congenital glaucoma, strabismus surgery without sutures, and keratoconus treatment techniques such as rapid crosslinking.
Evaluation of methods for measuring intraocular pressure after laser vision correction operations, studying the effect of microbial and pharmacological treatments such as ranbizumab in the treatment of resistant vascular glaucoma.
Research on the role of cytokines and growth factors in eye fluids and their effect on diseases such as glaucoma and diabetic retinopathy.
Objective: to evaluate the effectiveness and safety of combining two surgical procedures for the treatment of advanced congenital glaucoma.
Conclusion: conclusion: surgical Fusion is effective and safe in advanced cases
Results: a significant improvement in intraocular pressure and stabilization of the condition within two years.
Objective: to study the relationship between certain genetic changes, indicators of oxidative stress and the risk of developing closed-angle glaucoma.
Results: no statistical association was shown between genetic changes and the risk of disease, while indicators of oxidative stress were associated with increased intraocular pressure.
Conclusion: oxidative stress plays a greater role than the studied genetic factors in the development of the disease.
Objective: to study the accuracy of intraocular pressure measurement after laser vision correction operations.
Results: Lasik operations affect the accuracy of traditional measurement of intraocular pressure.
Objective: to evaluate the effectiveness of combination therapy with precision laser and ranbizumab in resistant vascular glaucoma.
Results: marked improvement in intraocular pressure and improvement of symptoms.
Conclusion: combination therapy is effective and safe.
Objective: to evaluate a new surgical technique for the treatment of secondary glaucoma caused by silicone oil..
Results: the technique is effective in reducing intraocular pressure and improving visual results.
Conclusion: the technique can be adopted in complex cases.
Objective: to study the role of certain immune factors in diabetic retinopathy..
Results: there is an association between the levels of these factors and the severity of Retinopathy..
Conclusion: these factors may be future therapeutic targets.
Objective: to evaluate the results of combining cataract surgery with chronic open glaucoma surgery.
Results: the technique is effective in improving vision and lowering intraocular pressure..
Conclusion: the combination of the two operations is safe and with good results.
Objective: to study the biomechanical properties of the cornea in asymmetric normal pressure glaucoma..
Results: there are differences in the properties of the cornea between the eyes in the same patient..
Conclusion: these characteristics may help to understand the development of the disease.
Objective: to compare the effectiveness of two surgical procedures in the treatment of resistant congenital glaucoma.
Results: both methods are effective, with slight differences in results and complications.
Conclusion: the choice between the two methods depends on the patient's condition.
Objective: to evaluate the results of Ahmed valve transplantation for the treatment of glaucoma after corneal transplantation over a period of 4 years.
Results: the valve is effective in lowering intraocular pressure with acceptable complication rates..
Conclusion: Ahmed valve implantation is a good option in these cases.
Objective: to compare the results of cataract surgery with or without Iridectomy in chronic closed-angle glaucoma.
Results: both methods are effective, with some differences in side effects.
Conclusion: consolidation may be better in some cases.
Objective: to compare the effectiveness of two surgical methods in the treatment of vascular glaucoma after preparing patients with drug and laser treatments.
Results: both methods are effective, with differences in complications..
Conclusion: the choice depends on the eye condition and the patient's response.
Objective: to study the effect of topical treatments for glaucoma on the thickness of the central cornea in the long term.
Results: some treatments may affect the thickness of the cornea, which affects the accuracy of measuring intraocular pressure.
Conclusion: these changes should be taken into account when following glaucoma patients.
Objective: to measure the levels of cytokines in eye fluids in glaucoma and cataract patients.
Results: marked differences in cytokine levels between groups.
Conclusion: cytokines have a role in the development of eye diseases and may be a future therapeutic target.
