Brief Summary
This study will examine potential factors in the aqueous humor that may contribute to the development or progression of macular edema or fibrosis (due to any underlying disease) in patients suffering from these conditions.

Outcome Measures
Primary Outcomes (1)
Correlation of pro-permeability and pro-fibrosis factor levels and receptor/signaling molecule activation with disease activity.
Baseline
Secondary Outcomes (2)
Correlation between reduction in foveal thickness and changes in aqueous levels of pro-permeability and pro-fibrosis factors from baseline to week 6 in the clinic cohort.
Baseline, week 6.
Correlation between changes in visual acuity and changes in the aqueous levels of pro-permeability and pro-fibrosis factors from baseline to week 6 in the clinic cohort.
Baseline, week 6.
Study Arms (2)
Clinic Patients
Patients from the clinic will be considered for enrollment if they are receiving an intraocular injection of a steroid as part of standard care for macular edema or progressive fibrosis. Clinic patients who are receiving an intraocular injection of steroid (Ozurdex) as part of standard care who agree to participate will have an anterior chamber (AC) tap just prior to the intraocular injection of steroid and a second AC tap at a follow up visit 6 ± 2 weeks after the steroid injection.
OR Patients
Patients undergoing surgery for one of the following conditions: (1) Proliferative Diabetic Retinopathy, (2) rhegmatogenous retinal detachment with PVR, (3) rhegmatogenous retinal detachment without PVR, (4) macular pucker, (5) macular hole. Surgical patients who agree to participate will have an anterior chamber (AC) tap at the beginning of surgery.
Interventions
Patients from the clinic will be considered for enrollment if they are receiving an intraocular injection of a steroid as part of standard care for macular edema or progressive fibrosis. Clinic patients who are receiving an intraocular injection of steroid (Ozurdex) as part of standard care who agree to participate will have an AC tap just prior to the intraocular injection of steroid and a second AC tap at a follow up visit 6 ± 2 weeks after the steroid injection.
The 60 patients from the operating room will be patients undergoing surgery for one of the following conditions: (1) Proliferative Diabetic Retinopathy, (2) rhegmatogenous retinal detachment with PVR, (3) rhegmatogenous retinal detachment without PVR, (4) macular pucker, (5) macula hole. All patients will be administered an AC (Anterior Chamber) tap just prior to the surgical procedure while in the OR.
A paracentesis removing about 0.1 ml of fluid from the front part of the eye (the aqueous chamber) will be performed in the operating room just prior to surgery or in the clinic. In the operating room, the AC tap is done after the eye is anesthetized and cleaned with 5% povidone iodine for the surgery. A 30-gauge needle attached to a tuberculin syringe is inserted into the AC and 0.1 ml of aqueous is removed. The wound is self-sealing and has no effect on the surgery. In the clinic, the AC tap is done after drops of proparacaine and 5% povidone iodine is placed in the eye and a lid speculum is inserted. The patient is seated at a slit lamp and a 30-gauge needle attached to a tuberculin syringe is inserted into the AC and 0.1 ml of aqueous is aspirated and then the needle is removed.
Eligibility Criteria
Proliferative Diabetic Retinopathy, Rhegmatogeous Retinal detachment with and without PVR, Macular pucker, Macular hole, Macular Edema and Fibrosis of the Retina,
You may qualify if:
- Signed informed consent and authorization of use and disclosure of protected health information
- Age \>= 18 years
- Undergoing surgery as part of standard care for one of the following conditions: (1) Proliferative Diabetic Retinopathy (PDR), (2) rhegmatogenous retinal detachment with PVR, (3) rhegmatogenous retinal detachment without PVR, (4) macular pucker, (5) macular hole OR receiving as part of standard care, an intraocular injection of a steroid for macular edema or progressive fibrosis.
You may not qualify if:
