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.
