OBJECTIVE: To compare 2 laser photocoagulation techniques for treatment of diabetic macular edema: the modified Early Treatment Diabetic Retinopathy Study (ETDRS) direct/grid photocoagulation technique and a potentially milder (but potentially more extensive) mild macular grid (MMG) laser technique in which microaneurysms are not treated directly and small mild burns are placed throughout the macula, whether or not edema is present.

METHODS: Two hundred sixty-three subjects (mean age, 59 ...

OBJECTIVE: There are many alternatives available to the vitreoretinal surgeon in the management of posteriorly dislocated intraocular lenses (IOL). The lens may be repositioned in the ciliary sulcus if there is adequate capsular support, but if this support is absent, it must either be sutured in place (to the sclera or iris) or exchanged for an anterior chamber (AC) IOL. Scleral-sutured IOLs can be associated with hemorrhage, cystoid macular edema, retinal detachment, and ...

OBJECTIVE: To evaluate the advisability of removing silicone oil from eyes after surgery for severe (with a classification of at least C-3) proliferative vitreoretinopathy.

DESIGN: Subgroup analysis of the Silicone Study, a randomized, multicentered, surgical trial.

SETTING: Community- and university-based clinics.

PATIENTS: Two hundred twenty-two eyes with severe proliferative vitreoretinopathy followed up in the Silicone Study.

INTERVENTIONS: Vitrectomy for proliferative ...

PURPOSE: To determine the microbiologic spectrum and antibiotic susceptibilities of infecting organisms in postoperative endophthalmitis and to evaluate the effects of operative factors on the microbiologic spectrum.

METHODS: Patients with bacterial endophthalmitis presenting within six weeks of cataract extraction or secondary intraocular lens implantation (IOL) were evaluated. Cultures and Gram stains were performed on intraocular specimens and susceptibility tests on the ...

PURPOSE: To compare pneumatic retinopexy and scleral buckling for repair of primary rhegmatogenous retinal detachment with respect to visual outcome, single-procedure reattachment rate, and development of proliferative vitreoretinopathy.

METHODS: A consecutive series of eyes initially treated with pneumatic retinopexy (n = 56) between March 1986 and February 1996 were compared with a selected group of eyes treated with scleral buckling (n = 86) with similar location and distribution of ...

PURPOSE: To examine retinal structure and changes in photoreceptor intensity after dark adaptation in patients with complete congenital stationary night blindness and Oguchi disease.

DESIGN: Prospective, observational case series.

METHODS: We recruited 3 patients with complete congenital stationary night blindness caused by mutations in GRM6, 2 brothers with Oguchi disease caused by mutations in GRK1, and 1 normal control. Retinal thickness was measured from optical coherence tomography ...

PURPOSE: To describe the clinical course and incidence of culture-proven postvitrectomy endophthalmitis in 18 patients from five academic centers and three private practices.

METHODS: Patients undergoing pars plana vitrectomy for recent trauma or endophthalmitis were excluded. The average age was 58 years (range, 21-85 year). Sixty-one percent of the patients (11/18) had diabetes mellitus. The indication for initial vitrectomy was vitreous hemorrhage (n = 10), macular epiretinal membrane ...

IMPORTANCE: The diagnostic accuracy of computer detection programs has been reported to be comparable to that of specialists and expert readers, but no computer detection programs have been validated in an independent cohort using an internationally recognized diabetic retinopathy (DR) standard.

OBJECTIVE: To determine the sensitivity and specificity of the Iowa Detection Program (IDP) to detect referable diabetic retinopathy (RDR).

DESIGN AND SETTING: In primary care DR clinics in ...

PURPOSE: The purpose of this study was to examine cone photoreceptor structure in retinitis pigmentosa (RP) and Usher syndrome using confocal and nonconfocal split-detector adaptive optics scanning light ophthalmoscopy (AOSLO).

METHODS: Nineteen subjects (11 RP, 8 Usher syndrome) underwent ophthalmic and genetic testing, spectral-domain optical coherence tomography (SD-OCT), and AOSLO imaging. Split-detector images obtained in 11 subjects (7 RP, 4 Usher syndrome) were used to assess ...

PURPOSE: To describe spectral-domain optical coherence tomography (SD-OCT) and adaptive optics (AO) imaging in hydroxychloroquine retinal toxicity.

METHODS: Two patients with long-term hydroxychloroquine use, subtle perifoveal ophthalmoscopic pigmentary changes, and bilateral perifoveal defects on automated Humphrey visual field (HVF) 10-2 perimetry were imaged using SD-OCT and AO.

RESULTS: SD-OCT images demonstrated loss of photoreceptor inner segment/outer segment (IS/OS) junction and ...

Eighteen eyes with coexisting cataract and vitreoretinal disease underwent combined phacoemulsification, pars plana vitrectomy, and posterior chamber lens implantation. Preoperative vitreoretinal disease included nonclearing vitreous hemorrhage (eight eyes), vitreous hemorrhage and tractional retinal detachment (three eyes), tractional retinal detachment (one eye), epiretinal membranes (three eyes), peripheral uveitis (two eyes), and a retained intraocular metallic foreign body (one ...

PURPOSE: To evaluate the association between human leukocyte antigen (HLA-DR15) specificity and intermediate uveitis.

METHODS: Eighteen patients diagnosed with intermediate uveitis underwent HLA-DR15 serotyping. Additionally, DNA-based phenotyping for a specific HLA-DR15 allele was performed in four patients. The clinical features of HLA-DR15-positive intermediate uveitis were compared with those of HLA-DR15-negative intermediate uveitis.

RESULTS: Thirteen of 18 patients (72%) were ...

OBJECTIVE: To analyze the data for cultures and Gram stains prospectively collected by protocol in the Endophthalmitis Vitrectomy Study.

DESIGN: Cultures of aqueous, undiluted vitreous, and (for patients who underwent vitrectomy) vitrectomy cassette fluid obtained from 420 patients were prepared on chocolate agar, in thioglycolate broth, and on Sabouraud dextrose agar; Gram stains of the aqueous and undiluted vitreous were made. Criteria were devised to distinguish true pathogens ...

PURPOSE: To compare images of photoreceptor layer disruptions obtained with optical coherence tomography (OCT) and adaptive optics scanning light ophthalmoscopy (AOSLO) in a variety of pathologic states.

METHODS: Five subjects with photoreceptor ellipsoid zone disruption as per OCT and clinical diagnoses of closed-globe blunt ocular trauma (n = 2), macular telangiectasia type 2 (n = 1), blue-cone monochromacy (n = 1), or cone-rod dystrophy (n = 1) were included. Images were acquired ...
