Study Notes

Fibrous Tissue in the Retina

Abnormal fibrous tissue in the retina can cause tractional retinal detachment, extending upwards and downwards.

Diabetic Retinopathy Screening

For Type 1 diabetes, screening should start after 5 years of diagnosis.
The reason is that Type 1 diabetes has a rapid onset and retinal effects may not be immediate.

Retinal Detachment Treatment

Scleral Buckle: This is the most common treatment for retinal detachment.
Par plana vitrectomy: This procedure is another treatment option.
Pneumatic Retinopexy: This procedure involves injecting a gas into the eye that pushes the retina back against the ocular wall.
PRP (Photocoagulation): Considered if aggressive fractional retinal detachment causes striations in the macula.

Exudative Retinal Detachment (ERD)

The exudative fluid causing ERD does not originate from the vitreous cavity.
This is because there is no break in the vitreous allowing access to the retina.
