Visual and surgical outcomes of retinal detachment following macular hole repair.

OBJECTIVE: To characterize 20 cases of retinal detachment (RD) following surgical repair of macular holes. METHODS: Retrospective review of 20 eyes in 16 patients (4 patients [25%] had bilateral macular hole repairs with subsequent RD) who developed RD in the same eye in which surgical repair of a macular hole had been performed. RESULTS: Twenty detachments in 16 patients were reviewed. The average duration between macular hole repair and presentation of RD was 5.5 weeks. The inferior retina was involved more frequently than the superior retina. A total of 76% of all breaks were located inferiorly. Ten of the 20 eyes were asymptomatic at the time the detachment was diagnosed. Of the 20 eyes, 19 underwent surgical repair, all with anatomic reattachment. At final follow-up, the macular hole was closed in all 20 eyes, and 60% of the patients had final visual acuity improved by 2 lines or more over that before their macular hole repair. CONCLUSION: Retinal detachment is a complication of macular hole surgery. These detachments tend to occur within the first 2 months of follow-up, and have a high success rate of anatomic reattachment with surgery. The occurrence of RD does not preclude improved final visual acuity.

Subretinal aspiration biopsy of ocular lymphoma.

PURPOSE: Large-cell lymphoma can be difficult to diagnose because vitreous biopsies may fail to disclose neoplastic cells. METHODS: We report one such case in which diagnosis was confirmed by subretinal aspiration of yellow-white infiltrates using a pars plana approach. RESULTS: A 67-year-old woman with recurrent bilateral uveitis was diagnosed with large-cell lymphoma by subretinal aspiration of yellow-white infiltrates after two vitreous biopsies and a concurrent retinal biopsy failed to confirm the diagnosis. CONCLUSIONS: When the suspicion of intraocular lymphoma remains high despite previous negative vitreous biopsies, retinal biopsy and aspiration biopsy of subretinal lesions may enhance the diagnostic yield.

Choroidal metastases from renal cell carcinoma.

BACKGROUND: Choroidal metastases from renal cell carcinoma are uncommon. The authors investigated the clinical characteristics of patients with renal cell carcinoma in whom choroidal metastases developed. METHODS: The clinical records of five patients with histopathologically confirmed renal cell carcinoma and choroidal metastases were reviewed retrospectively. RESULTS: In four patients, choroidal metastases were either the sole initial manifestation of disease or were the initial manifestation of metastatic disease. The interval from nephrectomy to the onset of ocular signs ranged from 6 to 18 years. A reddish-orange appearance of the tumor was present in two patients, but no pathognomonic features distinguishing these tumors from other choroidal metastases were identified. CONCLUSIONS: Ocular metastases may precede the diagnosis of renal cell carcinoma or may follow it by years or decades. This interval between its ocular and systemic presentation may be so prolonged as to obscure the relation between the choroidal metastases and the primary tumor. In patients with amelanotic or reddish choroidal lesions without known metastatic disease, evaluation of the kidney may be warranted as part of a metastatic workup to exclude metastatic renal cell carcinoma.

Posterior segment complications after vitrectomy for macular hole.

PURPOSE: The purpose of this study is to assess the rate of posterior segment complications after vitreous surgery for macular holes and to evaluate the effect of such complications on final visual outcome. METHODS: The authors reviewed retrospectively all cases of vitreous surgery for macular holes performed between June 1990 and October 1993. Among 98 patients with a followup of 3 months or more, all patients with posterior segment complications during the postoperative course were identified. The rate of complications was compared with that seen after vitreous surgery for macular pucker performed by the same surgeons. RESULTS: Posterior segment complications were noted in 23 (23%) of 98 patients. These included peripheral retinal breaks (3%), rhegmatogenous retinal detachment from a peripheral retinal break (14%), enlargement of the hole (2%), late reopening of the hole (2%), retinal pigment epithelium loss under the hole (1%), photic toxicity (1%), and endophthalmitis (1%). In 40% of these eyes, the final visual acuity was two lines or more below preoperative visual acuity. When compared with the macular pucker group, the rate of posterior segment complications, in particular the rate of peripheral retinal tears and detachments, was significantly higher (P < or = 0.05). CONCLUSIONS: The authors conclude that visually significant posterior segment complications may occur after vitrectomy for macular hole, and the rate of these complications appears to be higher than expected.
