Eye perfusion system. Balanced salt solution (BSS) solution was delivered into the eye via a 26-gauge needle. Intraocular pressure (IOP) was maintained at between 25 and 30 mmHg. A smaller caliber 30-gauge needle was used to create a venting port at 90${}^{\text{o}}$ away from the infusion port. A 26-gauge needle was inserted half-way between the infusion and venting ports to inject fluorescein.
