Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Dexamethasone implant can lead to retinal nerve fiber layer and optic nerve damage by both increasing intraocular pressure and its direct effect on neural tissue during the effective 6-month period.
