Background: Diabetic retinopathy is considered a common and specific microvascular complication of DM that develops over a period of time and causes irreversible blindness. The study aimed to: Evaluate the effect of an educational intervention for diabetic retinopathy patients on improving their knowledge and self-care practices. Method: Quasi-experimental research design was utilized in this study. Sample: A purposive sample of 100 patients from Mansoura Ophthalmic Hospital was included in this study and the sample had been divided equally into study and control groups. Tools: Data were collected using two tools; first tool was a structured interview questionnaire sheet and the second tool was self-care practices checklist. Main results: There were highly statistically significant differences among the study and control groups regarding their total knowledge and total self-care practices post implementing the educational intervention and at follow-up phases. In conclusion: Applying the educational intervention was effective in improving patients' knowledge and self-care practices. Recommendations: Ophthalmic nurses should be fully aware of their educational roles in preventing progression of the disease, collaboration between DM follow-up clinics and eye clinics in screening for DR was strongly recommended and this study should be replicated on a large sample to generalize its results.

Background: Nowadays, intraocular surgery is widely performed and the ophthalmic nurse is the backbone of the eye care. Any deficiency in providing adequate nursing care pre or post eye surgery can lead to serious complications. The study aimed to: Evaluate the effect of implementing the nursing guideline on nurses' performance regarding patients undergoing cataract or glaucoma surgery. Method: Quasi-experimental research design was utilized to conduct this study. Sample: A convenience sample of 36 nurses working at Ophthalmology Mansoura Hospital was included in this study. Tools: Data were collected using two tools, first tool was pre/post structured questionnaire sheet, and it included two parts; part 1-included socio demographic characteristics of the studied nurses and part 2-included nurses' knowledge regarding the care provided to patients with cataract or glaucoma surgery. Second tool was pre/post observa tion checklist for nurses' practice pre, and post surgery. Results: Post implementing the guideline; there were high statistical significant differences in nurses' knowledge, preoperative practice, and postoperative practice (p<0.001) and a statistical significant relation was fou nd between nurses' educational level with their knowledge, preoperative practice, and postoperative practice (p=0.044, 0.050, 0.048 respectively). Conclusion:Applying the designed nursing guideline is effective in improving nurses' knowledge, and practice regarding the care provided to patients with cataract or glaucoma surgery. Recommendation: It is recommended to; develop a specialized orientation program for the newly appointed nurses, provide the nurses with continuous training courses, set restrict supervision on nurses' application for infection control precautions, and encourage them to become involved in research studies.
