Two consecutive patients with idiopathic central serous chorioretinopathy and decreased vision subsequent to subfoveal choroidal neovascular membranes were treated with photodynamic therapy applied using the protocol of the Treatment of Age-Related Macular Degeneration with Photodynamic Therapy Study Group. Main outcome measures included best-corrected visual acuity, biomicroscopic appearance, and leakage on fluorescein and indocyanine green angiography. Photodynamic therapy offered anatomical, angiographic, and functional improvement.

Design: Interventional case report.
Method: A 48-year-old Caucasian man with unilateral exudative retinal detachment from diffuse retinal pigment epitheliopathy and visual acuity of 20/40 was managed with verteporfin PDT applied sequentially in three separate spots targeting all retinal pigment epithelium leaks identified with intravenous fluorescein angiography (IVFA).
Purpose: Retinal pigment epithelial changes described after vitreoretinal surgery may result from localized compression injury caused by intentional or inadvertent contact with vitreoretinal instruments. The authors evaluated these changes resulting from manipulation of the retina without frank retinal injury.
Methods: One eye each of six pigmented rabbits underwent surgery during which the inner retinal surface was touched at several points with a 20-gauge silicone-tipped subretinal fluid cannula without causing a retinal break or subretinal hemorrhage.
Purpose: We describe a new wide-field vitrectomy contact lens specifically designed to facilitate pediatric vitreoretinal surgery.
Design: Experimental study, instrument description.
Methods: A wide-field contact two-piece glass vitrectomy lens was designed with the largest diameter of 13.
Purpose: To determine the safety and efficacy of intravitreal triamcinolone acetonide (TAAC) injections in patients with refractory cystoid macular edema (CME) after cataract extraction.
Setting: LSU Eye Center, Louisiana State University Health Sciences Center, New Orleans, Louisiana, USA.
Methods: In this nonrandomized retrospective case review, 8 eyes of 8 patients with a history of pseudophakic CME recalcitrant to current standard treatment modalities were enrolled.
Purpose: To report a new adjustable-tip brush for induction of posterior hyaloid separation and epiretinal membrane peeling.
Design: Observational report.
Methods: The adjustable-tip brush made of 10-0 nylon was used during vitrectomy for a variety of vitreoretinal disorders to induce posterior vitreous detachment and to peel internal limiting membrane or epiretinal membranes.
Objective: To report two cases of recurrent anterior uveitis with sectoral iris atrophy and ocular hypertension during attacks caused by cytomegalovirus (CMV).
Design: Two observational case reports.
Participants: Two immunocompetent patients with a history of recurrent unilateral hypertensive anterior uveitis with sectoral iris atrophy were referred to us with the presumptive diagnosis of herpetic uveitis.
Purpose: To describe the effect of internal limiting membrane peeling in chronic recalcitrant pseudophakic cystoid macular edema.
Design: Two interventional case reports.
Methods: Two consecutive patients with chronic pseudophakic cystoid macular edema of 11-22 months duration, after uncomplicated cataract surgery, unresponsive to previous treatment, were enrolled.
Purpose: To describe a new high-speed pneumatic vitrectomy instrument capable of 2000 cuts/minute.
Design: Observational report.
Methods: A high-speed guillotine vitrector, developed to perform vitrectomy, with the ability to adjust from 1 to 2000 cuts/minute, was used in 80 consecutive vitreoretinal cases with a variety of diagnoses in a hospital setting.
