Long-term follow-up of anterior uveitis after cataract extraction and intraocular lens implantation.

PURPOSE: To assess whether cataract surgery and intraocular lens (IOL) implantation in patients with anterior uveitis interfere with the natural course of the ocular disease. SETTING: Tertiary care center at the University of Rome "La Sapienza", Rome, Italy. METHODS: Cataract extraction and IOL implantation were performed in 24 patients with uveitis-related cataract: 12 with Fuchs' heterochromic iridocyclitis (Group 1) and 12 with other types of anterior uveitis (Group 2). The mean follow-up in the 2 groups was 33.6 months and 24.8 months, respectively. The number and severity (inflammatory score) of uveitis relapses in all patients over the same period were recorded. RESULTS: After surgery, the mean number and severity of uveitis relapses decreased: Group 1, from 1.83 +/- 1.90 (SD) to 1.00 +/- 1.21 and from 1.08 +/- 0.90 to 0.92 +/- 0.67, respectively; Group 2, from 2.74 +/- 3.44 to 1.25 +/- 1.71 and from 1.83 +/- 1.10 to 1.25 +/- 0.75, respectively (P = .046). There were no statistically significant between-group differences. In Group 2, a trend toward worse visual rehabilitation was seen; this was significantly different from the result in Group 1 (P = .018) because of preoperative optic nerve damage, macula disease, or both. CONCLUSION: Cataract surgery and IOL implantation did not negatively influence the natural course of uveitis in patients with Fuchs' heterochromic iridocyclitis. Correct surgical timing, selection of cases, and adequate anti-inflammatory therapy may promote similar results in patients with other types of anterior uveitis.

Indocyanine green angiographic findings in idiopathic choroidal neovascularisation.

PURPOSE: The authors report the cases of two patients affected with idiopathic choroidal neovascularisation studied with combined fluorescein angiography and indocyanine green (ICG) angiography. In particular the presence of choroidal abnormalities at ICG angiography which could not be detected by fluorescein angiography was studied. METHODS: Both patients underwent a complete systemic and ocular assessment. Fluorescein angiography and ICG angiography were performed in a routine fashion at the time of presentation in both cases and after 14 months in the second patient. RESULTS: Results of the systemic investigations were unremarkable. A distinct dark rim surrounding the choroidal neovascular net was evident until the late phases of ICG angiography despite the presence of subretinal blood. Dilated choroidal vessels were observed beneath the neovascular membrane in both cases. In the first patient a hyperfluorescent area beyond the primary lesion was detected in the affected eye and a distinct leaking subfoveal choroidal venous vessel was found in the fellow eye. The second patient never showed other angiographic alterations either in the affected or in the fellow eye. CONCLUSIONS: ICG angiography has proved to be useful, both to better define and follow up the true extent of the pigment halo (healing response) around the neovascular membrane when subretinal blood and dye leakage at fluorescein angiography prevent its full appreciation, and to rule out other causes of choroidal neovascularisation in young healthy adults associated with either choroidal inflammatory focal lesions or choroidal vascular dynamic or inflammatory alterations.

Argon laser photocoagulation in the treatment of the palpebral lobe cysts of the lacrimal gland (dacryops).

Dacryops is a closed cyst that develops on the palpebral lobe of the lacrimal gland, manifesting in the region of the external canthus. Its slow and insidious growth causes mechanical and aesthetic problems that do not regress spontaneously. Treatment involves excision of the cyst while sparing the adjacent glandular tissues. In cases associated with hypolacrimation, marsupialization of the cyst is indicated. To obtain a reduction of the cyst to an aesthetically acceptable level in cases of simple dacryops, the authors suggest argon laser therapy, which avoids the risks related to surgery and general anesthesia and eliminates the need for hospitalization. Two patients with simple dacryops were treated with blue-green argon laser under local anesthesia. At the end of follow-up, the cysts had been clinically reduced in volume and were not visible by external examination. In cases of simple dacryops, laser therapy is suitable for the reduction of the cyst. Photocoagulation treatment is not advisable in cases that are complicated by fistulas or where the clinical presentation is atypical.
