Insights

Confluent laser photocoagulation effectively treated threshold retinopathy of prematurity in premature infants, showing a low progression rate to advanced stages. This method demonstrated comparable outcomes and complications to nonconfluent laser treatments.

Area of Science:

  • Ophthalmology
  • Neonatology
  • Pediatric Surgery

Background:

  • Retinopathy of prematurity (ROP) is a leading cause of childhood blindness.
  • Laser photocoagulation is a standard treatment for threshold ROP.
  • The optimal pattern and density of laser spots remain under investigation.

Purpose of the Study:

  • To evaluate the efficacy, outcomes, and complications of the confluent laser technique for threshold ROP in premature infants.
  • To compare outcomes with existing nonconfluent laser treatment methods.

Main Methods:

  • Retrospective chart review of 100 eyes from 51 premature infants with threshold ROP treated between 2003 and 2006.
  • Confluent laser treatment applied 360 degrees anterior to the ridge.
  • Evaluation of progression, retreatment, complications, structural outcomes, and refractive error.

Main Results:

  • Mean gestational age was 28 weeks; mean birth weight was 1,065 g.
  • Progression to stage 4 or 5 ROP occurred in only 6% of eyes.
  • Complications included cataract, vitreous hemorrhage, corneal edema, and macular dragging; mean spherical equivalent was -3.80 D.

Conclusions:

  • Confluent laser photocoagulation is effective in managing threshold ROP, with a low rate of progression to advanced stages.
  • The need for additional treatment was minimal.
  • Complication and structural outcome rates were comparable to nonconfluent laser patterns.

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.

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...
