Diabetic Retinopathy

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...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Open Angle Glaucoma: Treatment

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...

Angle Closure Glaucoma: Treatment

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...

Summary

Cataract surgery can worsen diabetic macular edema up to 3 months post-op, especially in diabetic retinopathy patients. Edema typically resolves gradually afterward, with some cases resolving spontaneously.

Area of Science:

Ophthalmology
Retinal Diseases
Surgical Outcomes

Background:

Diabetic retinopathy (DR) is a leading cause of vision loss.
Phacoemulsification is a common cataract surgery technique.
Macular edema can affect visual acuity in patients with and without DR.

Purpose of the Study:

To quantitatively assess macular edema changes after phacoemulsification surgery.
To compare outcomes in eyes with diabetic retinopathy versus those without.

Main Methods:

Optical coherence tomography (OCT) used for measurements.
Foveal thickness and macular volume tracked pre- and post-surgery (3, 6, 12 months).
Diabetic macular edema grading performed.

Main Results:

Macular edema and foveal thickness increased significantly at 3 months post-surgery in the DR group compared to the no-DR group.
Edema worsened in 23.5% of DR eyes versus 2.9% of no-DR eyes.
Spontaneous resolution of post-surgical edema occurred in 33.3% of affected eyes.

Conclusions:

Macular edema and its grade can increase up to 3 months after cataract surgery, particularly in patients with diabetic retinopathy.
Edema tends to gradually decrease after 3 months.
Some post-surgical edema resolves spontaneously, with more pronounced changes observed in eyes with DR.
