RESUMO
We report the clinical and angiographic features as well as the natural course of an optic disk and juxtapapillary combined pigment epithelial and retinal hamartoma in a 23-year-old white girl. The patient presented 3 episodes of recurrent vitreous hemorrhages in the first 4 years of follow-up, which were spontaneously and totally absorbed. During the last 6 years, she was absolutely free of any ocular symptom. The tumor did not show any growth during the 10 years of follow-up. The digital indocyanine green angiography, which was normal in the early frames, revealed a mild, patchy hyperfluorescence corresponding to the tumor location in the late phase.

We present the cases of 2 consecutive siblings with bilateral macular lesions, for which there is strong clinical and laboratory evidence supporting the diagnosis of congenital ocular toxoplasmosis. These cases raise the possibility of maternal parasitemia during Toxoplasma gondii reinfection, leading to transmission to the fetus and congenital ocular toxoplasmosis despite prior immunity and lack of an immune disturbance in the mother.

PURPOSE: To evaluate the presence and the evolution of cyst formation in optic disc pit maculopathy. METHODS: In this prospective study, 18 cases with optic disc pit maculopathy were studied. Five of them showed cyst formation in the fovea at the initial examination. The fundus findings were documented with slit-lamp biomicroscopy, indirect ophthalmoscopy, and stereoscopic photography of the posterior pole. All 5 patients were treated with a macular scleral buckle procedure. RESULTS: The presence of cysts in the elevated macula depends on the grade of the disease. Cyst formation can develop not only in the later stage of the disease but also quite early. In all 5 patients cyst formation gradually decreased and finally disappeared after the surgical procedure. CONCLUSIONS: Cyst formation is an entity which accompanies the macular detachment associated with optic disc pit. The development of the cysts has been noticed after the establishment of the schisis-like separation and before or in conjunction with the formation of a lamellar macular hole which usually accompanies the optic disc pit maculopathy.
