Abstract

Insights

Subthreshold micropulse diode laser photocoagulation combined with direct photocoagulation effectively treats diabetic macular edema, maintaining visual acuity and reducing retinal thickness for at least six months.

Area of Science:

  • Ophthalmology
  • Diabetic Retinopathy Treatment

Background:

  • Diabetic macular edema (DME) is a leading cause of vision loss in diabetic patients.
  • Current treatments aim to reduce macular edema and preserve visual function.

Purpose of the Study:

  • To evaluate the efficacy of combining subthreshold micropulse diode laser photocoagulation (SMDLP) with direct photocoagulation for DME.
  • To assess the impact on visual acuity and central macular thickness (CMT).

Main Methods:

  • Twenty-one eyes of 20 patients with DME were treated.
  • SMDLP was followed by direct photocoagulation for microaneurysms within one month.
  • Visual acuity and CMT were assessed using OCT before and after treatment.

Main Results:

  • Central macular thickness (CMT) significantly decreased at 3 and 6 months post-treatment (p=0.018 and p=0.004, respectively).
  • Visual acuity was maintained or improved in all patients (100%) at 6 months.
  • No significant change in mean visual acuity was observed at 3 or 6 months.

Conclusions:

  • Combined SMDLP and direct photocoagulation is an effective treatment for DME.
  • This combined approach maintains visual acuity and reduces macular edema for at least six months.

Diabetic Retinopathy

DefinitionDiabetic retinopathy is a microvascular complication of diabetes affecting the retinal blood vessels.Risk FactorsDiabetic retinopathy is present in almost all individuals with type 1 diabetes and more than 60% of those with type 2 diabetes after two decades of disease.The risk increases with poor glycemic control, hypertension, dyslipidemia, smoking, pregnancy, and puberty.Although cataracts and glaucoma are also more frequent in people with diabetes, retinopathy remains the leading...
Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...
Open Angle Glaucoma: Treatment01:27

Open Angle Glaucoma: Treatment

In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...
