September 2024
Purpose: To report the clinical findings, treatments, and outcomes in a series of patients with vitreous metastasis from cutaneous melanoma.
Methods: This single-center, retrospective, interventional case series included patients with biopsy-confirmed vitreous metastasis from cutaneous melanoma diagnosed between 1997 and 2020. Standard 23- or 25-gauge pars plana vitrectomy was performed for diagnostic sampling.
Purpose: To report two cases of acute exudative polymorphous vitelliform maculopathy.
Design: Observational case reports.
Methods: Fluorescein angiography, optical coherence tomography, and electrophysiology were performed.
Purpose: Choroidal neovascularisation (CNV) occurs rarely following laser photocoagulation for macular oedema in diabetic retinopathy, and its management is not well established. We report the clinical course and visual outcomes in a series of patients who underwent surgical extraction of the CNV membrane.
Methods: A retrospective review of 4 cases was carried out.
Purpose: To describe the clinical characteristics and management of retinal injuries caused by soccer ball impact as well as the mechanism of injury, prognostic features, risk factors, and possible prevention strategies.
Methods: Thirteen cases of soccer ball injuries from retina referral practices were retrospectively reviewed, with attention to the mechanism of associated ocular complications and the anatomic and visual outcomes.
Results: Soccer ball injuries occurred in both male and female patients (9 male, 4 female) with ages ranging from 8 to 21 years (median 14 years).
Purpose: This report evaluates the clinical characteristics of surfing-related ocular trauma to learn the nature of such injuries and propose possible preventive measures.
Methods: The authors reviewed 11 cases of surfing-related eye injuries caused by direct trauma from the surfboard, studying their mechanism of injury, the associated ocular complications, and the anatomic and visual outcomes of surgical repair.
Results: Surfing-related ocular injuries occurred exclusively in young males (mean age, 24.

Ophthalmic Surg Lasers
March 1998
Background And Objective: To assess the outcomes of vitreoretinal surgery in the treatment of vision-threatening posterior segment complications of X-linked retinoschisis.
Patients And Methods: The authors performed a retrospective analysis of 16 eyes from 11 patients who underwent vitreoretinal surgery. All the patients had a documented positive family history of X-linked retinoschisis, and all patients had bilateral macular disease.
Purpose: Tumor-infiltrating lymphocytes (TIL) were recovered from a series of human choroidal melanomas and expanded in cultures containing interleukin-2 (IL-2) to determine whether TIL contained cytotoxic cells that could be activated in vitro.
Methods: TIL were recovered from six ocular melanoma patients and expanded in vitro with IL-2. Cytotoxic activity was tested in a standard 4-hr 51Cr release assay.
Early treatment of posterior retinopathy of prematurity: a controlled trial.
Ophthalmology
November 1997
Objective: The purpose of the study is to assess the possible benefits of early laser treatment for posterior retinopathy of prematurity (ROP) and to provide data concerning the natural history of posterior ROP.
Design: The study design was a prospective, multicenter, randomized trial.
Participants: A total of 19 infants with prethreshold posterior ROP were studied.
Purpose: To report giant retinal tear and retinal detachment as a complication of attempted removal of intravitreal lens fragments at the time of cataract surgery and to evaluate the anatomic and visual acuity outcomes of pars plana vitrectomy and retinal reattachment surgery.
Methods: Retrospectively, 10 patients with giant retinal tear, retinal detachment, and intravitreal lens fragments in 10 eyes were reviewed.
Results: In 10 eyes, retrieval of intravitreal lens fragments using the limbal approach by deep vitrectomy, copious vitreous cavity irrigation, or deep vitreous cavity phacoemulsification had been attempted by the anterior segment surgeon at the time of cataract surgery in each patient.
Purpose: To develop a classification system for mechanical injuries of the eye.
Methods: The Ocular Trauma Classification Group, a committee of 13 ophthalmologists from seven separate institutions, was organized to discuss the standardization of ocular trauma classification. To develop the classification system, the group reviewed trauma classification systems in ophthalmology and general medicine and, in detail, reports on the characteristics and outcomes of eye trauma, then established a classification system based on standard terminology and features of eye injuries at initial examination that have demonstrated prognostic significance.
Purpose: The purpose of the study is to evaluate the effect of vitrectomy on secondary glaucoma and visual acuity outcomes in patients with retained lens fragments after phacoemulsification.
Methods: A retrospective analysis of 126 patients who had vitrectomy for retained lens fragments after phacoemulsification during the 3-year period between January 1, 1993, and December 31, 1995.
Results: Glaucoma, defined as an intraocular pressure of greater than or equal to 30 mmHg, occurred in 42 (36.
Treatment outcomes in a 10-year study of endogenous fungal endophthalmitis.
Ophthalmic Surg Lasers
March 1997
Background And Objective: To review prevalence of organisms, associated factors, and treatment outcomes from one medical center's 10-year experience managing culture-proven endogenous fungal endophthalmitis (EFE).
Patients And Methods: The authors retrospectively reviewed the microbiology and corresponding clinical records of patients diagnosed as having culture-proven EFE at the Bascom Palmer Eye Institute during a 10-year period.
Results: Culture-proven EFE occurred in 20 eyes of 18 patients.
Objective: To test the therapeutic effect of periocular corticosteroid injection on outcome, vitreous cellular infiltrate, and vitreous soluble growth-stimulating activity in an experimental model of tractional retinal detachment resulting from proliferative vitreoretinopathy.
Methods: An experimental model of proliferative vitreoretinopathy was induced in rabbits, which then were selected randomly to receive either periocular methylprednisolone acetate injection treatment or a placebo injection (control). Animals were examined and monitored to determine the degree of retinal detachment and proliferative vitreoretinopathy at weekly intervals for 4 weeks.
Impact of cultures on management decisions following surgical repair of penetrating ocular trauma.
Ophthalmic Surg Lasers
January 1997
Background And Objective: The purpose of this study was to evaluate the utility of routine bacterial and fungal cultures in the diagnosis of endophthalmitis and in the subsequent management of patients following penetrating ocular trauma.
Patients And Methods: The medical records of 70 consecutive patients with penetrating ocular trauma for whom intraoperative bacterial and fungal cultures had been obtained from the wound, aqueous, vitreous, and/or intraocular foreign body (IOFB) were retrospectively reviewed. The incidences of infection among eyes with and without a clinical diagnosis of infection were compared.
Purpose: Ocular missile injuries often involve the lens. Some have suggested that lens capsular violation by a foreign body is an indication for immediate lens removal. Sometimes, however, the resultant lens opacity may remain localized without visual compromise.

Purpose: To review the treatment and outcomes of patients presenting with concurrent endophthalmitis and retained lens fragments after phacoemulsification.
Methods: A retrospective chart review was conducted on patients presenting with culture-proven endophthalmitis and retained lens fragments after phacoemulsification between 1990 and 1994.
Results: Five patients were identified with culture-proven endophthalmitis and retained lens fragments after phacoemulsification.
Purpose: To evaluate the surgical results in a series of patients with diabetic macular edema associated with traction from a thickened and taut posterior hyaloid membrane and to identify features associated with better visual outcome.
Methods: We reviewed the clinical records of ten consecutive patients who underwent pars plana vitrectomy in one eye for diabetic macular edema that was preoperatively attributed to thickening and traction of the posterior hyaloid membrane.
Results: Best-corrected, preoperative visual acuity was 20/200 in seven eyes, 20/300 in one eye, and 20/400 in two eyes.
Purpose: Bacillus cereus endophthalmitis occurring after penetrating ocular trauma has been almost always associated with a poor visual outcome. The purpose of our study was to review and report patients who had useful visual acuity outcomes.
Methods: The study group consisted of five patients from a single medical center with penetrating ocular trauma and endophthalmitis caused by B.
Purpose: We studied reversible loss of light perception after vitreoretinal surgery to show that functional vision can return in some patients.
Methods: We reviewed the medical records of seven patients who had postoperative reversible loss of light perception in the eye that underwent vitreoretinal surgery. Differences in the postoperative courses and interventions were studied.
Purpose: To identify clinical characteristics that were associated with an increased incidence of endophthalmitis in eyes with penetrating ocular trauma.
Methods: In part 1, a retrospective analysis was performed on 258 consecutive patients with penetrating ocular trauma presenting to the Bascom Palmer Eye Institute between October 1987 and January 1991. In part 2 of the study, 28 consecutive patients with culture-proven endophthalmitis were identified from the Clinical Microbiology Registry from April 1987 through September 1987 and February 1991 through August 1993.
Pars plana vitrectomy for chronic pseudophakic cystoid macular edema.
Am J Ophthalmol
September 1995
Purpose: We determined the efficacy of pars plana vitrectomy in a series of patients with chronic pseudophakic cystoid macular edema.
Methods: Clinical records were reviewed on 24 consecutive patients who underwent pars plana vitrectomy in one eye for chronic pseudophakic cystoid macular edema. All 24 patients had failed to improve on medical therapy and had preoperative evidence of either vitreous adhesions to anterior segment structures (23 eyes) or iris capture of the intraocular lens (one eye).
Purpose: To evaluate the clinical outcome of patients who underwent lensectomy and intraocular lens (IOL) implantation at the time of primary repair of a penetrating ocular injury.
Methods: A review of 14 patients who sustained cataracts and lens rupture in the setting of a corneal laceration to determine anatomic and visual outcome, in addition to complications related to the primary IOL.
Results: The IOL remained anatomically stable in all 14 patients with no complications encountered at implantation or after surgery.
