Summary
Diabetic retinopathy (DR) affects over half of diabetes mellitus patients. Laser photocoagulation, including panretinal photocoagulation, is effective for preproliferative and proliferative DR, especially in pregnant individuals.
Area of Science:
- Ophthalmology
- Endocrinology
- Clinical Research
Background:
- Diabetic retinopathy (DR) is a significant complication of diabetes mellitus.
- Understanding the prevalence and progression of DR is crucial for patient management.
- Current treatment options for advanced DR require evaluation.
Purpose of the Study:
- To determine the prevalence of diabetic retinopathy in a cohort of diabetes mellitus patients.
- To assess the effectiveness of laser photocoagulation for preproliferative and proliferative DR.
- To evaluate panretinal photocoagulation in pregnant patients with proliferative DR.
Main Methods:
- Clinical examination of 662 diabetes mellitus patients.
- Prevalence assessment of diabetic retinopathy stages (preproliferative and proliferative).
- Analysis of treatment outcomes for laser photocoagulation and panretinal photocoagulation.
Main Results:
- A prevalence of 51.3% for diabetic retinopathy was observed in the study population.
- 7.6% of cases presented with preproliferative DR and 7% with proliferative DR.
- Laser photocoagulation demonstrated effectiveness for advanced DR stages; panretinal photocoagulation was effective for pregnant patients with proliferative DR.
Conclusions:
- Diabetic retinopathy is highly prevalent in diabetes mellitus patients.
- Laser photocoagulation is a recommended treatment for preproliferative and proliferative diabetic retinopathy.
- Panretinal photocoagulation offers an effective treatment for pregnant patients with proliferative diabetic retinopathy.
