Late swelling and removal of Miragel buckles: a comparison with silicone indentations.

Background: To describe the indications for removal of Miragel episcleral buckles and to compare them with removed silicone sponges and solid silicone indentations.

Methods: Retrospective analysis of the charts of patients successfully treated for retinal detachment in whom the episcleral buckle was removed after surgery, with a minimal follow-up of 6 months.

Results: In a series of 90 eyes of 90 patients, including 38 cases of Miragel elements, 25 cases of solid silicone, and 27 cases of silicone sponge removal, the duration of indentation before removal was significantly longer with Miragel (91.

Diagnosis of toxoplasmic retinochoroiditis with atypical clinical features.

Purpose: To determine the value of aqueous humor analysis for confirming the diagnosis of ocular toxoplasmosis in patients who present with atypical clinical features and to relate the results of local antibody production and polymerase chain reaction (PCR) with the extent of active retinitis and the immune status of the patient.

Design: Retrospective case series.

Methods: Sixty-seven consecutive patients with retinitis or retinochoroiditis that was clinically consistent with atypical ocular toxoplasmosis underwent diagnostic anterior chamber paracentesis and serological studies.

Cryoextraction of episcleral Miragel buckle elements: a new technique to reduce fragmentation.

A step-by-step description of a surgical technique for episcleral Miragel buckle removal is reported. After dissection of the conjunctiva and the capsule surrounding the Miragel element, the extremity of the buckle is pulled out with a cryoprobe. The removal of Miragel episcleral buckle with the cryoprobe is a safe and effective technique with a low fragmentation rate and a reduction of the surgical risk related to the use of sharp forceps near a possibly weakened sclera.
