ABSTRACT
PURPOSE: To evaluate the role of vitrectomy in patients with decreased visual acuity solely attributable to asteroid hyalosis. METHOD: We retrospectively reviewed the records of patients with asteroid hyalosis and identified those who underwent vitrectomy for symptomatic asteroid hyalosis alone. RESULTS: After vitrectomy, nine of 10 eyes (10 patients) had at least 1 line of improvement in nonstandardized best-corrected visual acuity. In one eye, vision was unchanged postoperatively. The average gain was 3.44 lines. CONCLUSIONS: A small percentage of patients with asteroid hyalosis have decreased visual acuity caused solely or primarily by the asteroid hyalosis. Vitrectomy in these patients may alleviate symptoms and improve visual acuity.

Inadvertent cyclodialysis cleft formation is a rare complication of intraocular surgery. We report a patient in whom a hypotonus cyclodialysis cleft developed following the removal of an anterior chamber intraocular lens. The cleft closed and the hypotony resolved after 1 month of topical atropine therapy.

Diabetic retinopathy is a major cause of morbidity and the leading cause of legal blindness in working-age persons in the United States. Retinopathy affects both juvenile-onset and noninsulin dependent diabetics. Most visual loss occurs in patients because they are seen late in the course of their disease. Several clinical trials have aided in establishing recommended screening and referral guidelines for patients with diabetes mellitus. Treatment strategies based on clinical trials are reviewed as well as the importance of control of both hyperglycemia and hypertension. Ocular findings are illustrated and discussed. The primary care physician can substantially reduce the risk of blindness and visual impairment in diabetic patients by prompt recognition of the ocular findings and understanding the importance of timely ophthalmologic evaluation.

Renal cell carcinoma (RCC) is a tumor of middle-aged men that metastasizes to the lung, liver, and bone. Few cases of RCC metastatic to the orbit have been reported. When this tumor spreads to the orbit, the orbital metastasis is likely to be the first indication of the cancer. We report the case of a 53-year-old man with widespread metastatic RCC whose first sign of disease was a metastatic orbital tumor. External and ocular examination and computed tomographic and histopathologic findings are described. The clinical characteristics, treatment, and prognosis of metastatic RCC are discussed.

A 35-year-old man with a history of repeated previous facial injuries presented with acute onset of a right orbital mass less than 2 weeks after blunt trauma to the right eye. Orbital B-scan ultrasonography and computed tomography showed an intraconal cystic lesion. The tumor was excised via lateral orbitotomy. Pathologic evaluation demonstrated a hematic cyst containing fresh blood. The presence of hemosiderin in the cyst wall suggested recent bleeding in a preexisting orbital hemorrhagic lesion. Patients with hematic cysts of the orbit usually present with a subperiosteal mass months to years after trauma.

Seventy-six patients with mycosis fungoides (MF) were given topical mechlorethamine hydrochloride therapy. Allergic contact hypersensitivity reactions to the drug developed in 51 patients (67.1%). Sixty-four patients of the original 76 continued therapy, with 43 (67.2%) achieving a complete remission and 12 (18.8%) achieving a partial remission. Stage I disease responded significantly better than did subsequent, more severe disease stages. The median times to complete remission were 5.6 months, 32.3 months, and 22.3 months for stage I, II, and III disease, respectively. The conditions of patients with contact sensitivity did not respond better than those of patients without contact sensitivity. Patients with substage A disease did not respond better patients with substage B disease. These findings are encouraging and indicate that the use of topically applied mechlorethamine for early-stage MF should be continued, despite the development of contact dermatitis to the drug.
