Ophthalmic dirofilariasis.
PURPOSE: To report a rare case of ophthalmic dirofilariasis in a 68-year-old man with sudden, intense pain and itching in the left eye. The nematode was located in the eye and recognized as Dirofilaria repens. METHODS: Slit-lamp examination disclosed a moving nematelminth under the bulbar conjunctiva of the left eye. The nematode was surgically removed. RESULTS: The nematelminth surgically removed from the subconjunctival space was identified as D repens on the basis of transverse sections and its macroscopic characteristics. CONCLUSION: It is important to identify the nematode as D repens, based on both its microscopic and macroscopic characteristics, to avoid treatment with anthelminthic agents. The surgical removal of the worm is the sole recommended treatment.

8 mm bimedial rectus recession in infantile esotropia of 80-90 prism dioptres.
Sixteen patients with large angle infantile esotropia with deviations of 80-90 prism dioptres were operated at the age of about 2 years. All patients underwent 8 mm bilateral medial rectus recessions. At the last follow up examination, 6 to 48 months postoperatively (average 16.3 months), successful horizontal alignment was achieved in 12 patients (75%). Four patients (25%) were undercorrected. Clinically significant limitation of adduction or convergence was not observed postoperatively in any of the patients. Consecutive exotropia was not encountered in this series but a longer follow up is probably needed in order to assess its delayed appearance. These results suggest that 8 mm recession of the medial recti is an effective procedure for the correction of large angle infantile esotropia of 80-90 prism dioptres and can be considered as an acceptable alternative to operations on three or four muscles.

Bilateral medial rectus recession in convergence excess esotropia, with and without distance orthophoria.
PURPOSE: To evaluate the effectivity and safety of bilateral medial rectus recession for the correction of acquired convergence excess esotropia, with and without distance orthophoria. METHODS: Thirty-five pediatric patients with acquired convergence excess esotropia were operated with bilateral medial rectus recessions based on the near angle measured through the distance correction. Preoperatively, in 26 patients, full hypermetropic correction did not fully correct the distance angle; these patients were operated for the residual angle for distance and near. In nine patients full hypermetropic correction produced distance orthophoria and these cases also had near orthophoria through a near add; these patients could have used bifocals, but surgery was chosen instead. RESULTS: Postoperatively, 19 of the 26 patients with distance esotropia (73%) and 6 of the 9 with distance orthophoria (66.6%) were successfully aligned. Consecutive exotropia developed in two patients (7.6%) in the distance esotropia group and one (11.1%) in the distance orthophoria group. CONCLUSIONS: These results suggest that bilateral recession of the medial recti based on the near deviation is effective in eliminating the near angle in convergence excess esotropia. In patients with distance orthophoria this operation can be used as an initial treatment instead of bifocals. Although the risk of consecutive exotropia was low in this series, a larger number of patients would determine its actual rate more accurately.
