Transpupillary thermotherapy of juxtafoveal recurrent choroidal neovascularization.

PURPOSE: To evaluate the effectiveness of low power transpupillary thermotherapy (TTT) in treating juxtafoveal recurrent choroidal neovascularization (CNV) after laser photocoagulation in patients with age-related macular degeneration (ARMD). METHODS: Eight eyes of eight patients with ARMD and juxtafoveal recurrent CNV were treated with low power TTT, delivered using an 810-nm diode laser with 350 mW, 2.0 mm spot, and 1-minute duration. Visual acuity (VA) ranged from 20/100 to 20/50. Treatment effect was evaluated by fluorescein angiography, indocyanine green angiography, and VA measurements (Early Treatment Diabetic Retinopathy Study) at 1-week, 2-week, and monthly follow-up visits. RESULTS: No retinal damage was visible ophthalmoscopically during treatment. At the first follow-up visit, seven eyes had obliteration of CNV and one eye required a second TTT application. VA was unchanged in six eyes, improved in one eye, and worsened in one eye. Recurrences occurred in all eyes between 1 and 7 months after TTT and were treated with photodynamic therapy (PDT). More than two PDT treatments were performed in each eye in the year after recurrence. CONCLUSIONS: Low power TTT is as able to close juxtafoveal recurrent CNV as is high power conventional laser photocoagulation but does not prevent recurrences. Further intervention with TTT in order to treat recurrences is under investigation.

Grid laser treatment of occult choroidal neovascularization in age related macular degeneration.

Laser photocoagulation treatment of occult choroidal neovascularization (CNV) in age related macular degeneration has been up to now discouraging. We report a randomized clinical trial comparing 'grid' laser treatment versus the natural course in 24 eyes with this kind of neovascularization. In 12 eyes a low energy scatter photocoagulation was applied to the areas of presumed CNV and abnormal retinal pigment epithelium, sparing the fovea. The follow-up ranged from 1 to 3 years. At the three months follow-up visit, the subretinal exudation appeared reduced in 40% of the treated eyes and in none of the control eyes. During the period of follow-up the occult CNV turned to classic CNV in 4 treated and in 4 untreated eyes. At the last examination (average follow-up 18 months), anatomical and functional conditions were not significantly different in the two groups. Our data fail to show a beneficial long-term effect of grid laser treatment for occult CNV; no iatrogenic complications were seen in our series.

Pattern dystrophy of the retinal pigment epithelium with vitelliform macular lesion: evolution in ten years.

We report an unusual case of primary dystrophy of the retinal pigment epithelium (RPE) in which a vitelliform macular appearance was associated with reticular hyperpigmentation resembling the pattern dystrophies of the RPE. The entire evolution of the disease was observed and documented step-by-step during a 10-year follow-up. During the progressive change of the lesions morphologic characteristics of butterfly, reticular and macroreticular dystrophy as well as Best's macular dystrophy could be seen. Pathogenetic relationships between all of these dystrophies of the RPE can be supposed.

Classification of proliferative diabetic retinopathy.

Using panretinal fluorescein angiography, three patterns (A, B, C) of capillary nonperfusion were identified in 308 eyes with proliferative diabetic retinopathy. Statistical analysis showed that there was a significant association with different retinal complications and clinical parameters. Pattern A (83.7%: midperipheral location of capillary nonperfusion) occurs in type I and II diabetes and is associated with early retinal neovascularization and focal macular edema. Pattern B (8.1%: capillary exclusions disseminated on the whole retina) is typical of young type-I diabetics and is complicated by early disc new vessels and ischemic maculopathy. Pattern C (8.1%: capillary nonperfusion confined to the peripheral retina) is observed in type-I diabetic females and associated with multiple, retinal new vessels, without maculopathy. This study also demonstrated that eyes with pattern B retinal ischemia respond less well to laser treatment than eyes with other pattern types. Various pathogenetic factors could lead to these three distinct types of proliferative diabetic retinopathy.

Mesectodermal leiomyoma of the ciliary body extending into the anterior chamber.

A neoplasm of the ciliary body extending from the equator to the iris and the anterior chamber was observed in an 18-year old girl. Because the visual acuity was lost and the clinical diagnosis was uncertain the eye was enucleated. Both optic and electron microscopic investigations allowed the diagnosis of the mesectodermal type of leiomyoma of the ciliary body.

Vascular changes in rhegmatogenous retinal detachment.

The author studied by fluorescein angiography the vascular conditions in 50 cases of rhegmatogenous detachment. Capillary dilatation and hyperpermeability were observed on the detached retina and can be considered as an autoregulation phenomenon secondary to tissular hypoxia. Diffuse peripheral vascular occlusions were a typical finding in detachments with peripheral holes. In these cases a preexisting retinal perfusion defect was probably exaggerated by the increased resistances secondary to the detachment.

Densitometric analysis of macular fluorescein angiography.

The authors analyze the fluorescein angiographic features of the macula by means of an image processor. The densitometric variations occurring during the various angiographic phases, in the various age-groups of the subjects and with different retinal adaptations, are studied.

Fundus angiography with fluorescein-labelled peptide fraction from bovine factor VIII: correlation with histologic findings.

A peptide fraction (VUEFFE) obtained from bovine factor VIII, with a high affinity for vessel endothelium, was bound to fluorescein and used for angiography in rabbits. Several eyes had undergone laser photocoagulation on the retina. The location of the dye was studied histologically with fluorescence microscopy on the enucleated, freeze-dried eyes. The angiographic and histologic findings were compared with findings obtained using sodium fluorescein. Fluorescein-labelled VUEFFE gave a longer lasting fluorescence of the retinal vessels with histologic evidence of dye deposition on the vessel wall. It also showed marked affinity for the photocoagulated tissues, giving intense and prolonged staining of the laser burns. Possible clinical applications are discussed.
