[2. Diagnostic resources and clinical indications].

Preliminary investigations, dedicated to the diagnostic application of three-dimension ultrasonic angioreconstruction, confirmed the feasibility of using the above method in ophthalmologic practice in cases of suspected intraocular and orbital neoplasms. 32 patients (37 eyes) with various pathologies of the eye and orbital cavity, including choroidal melanoma, facial angiomatosis, retinal detachment, chronic uveitis etc.) were examined. The results are indicative of that the three-dimension ultrasonic angioreconstruction makes it possible to detect the latent vascular neoplasms, which cannot be defined by the standard visual and ultrasonic examinations, and the dislocation of structural elements of the eyeball tunics. Besides, it provides for evaluating their special localization and their interrelations with the neighboring anatomic elements.

[The first results of phase IIA of clinical studies of photodynamic therapy for subretinal neovascular membranes with photosense].

The subretinal neovascular membrane (SNM) is a common complication of diseases, such as senile macular degeneration, myopia, pseudohistoplasmic syndrome, and many others. There is no algorithm of treatment for this pathology in today's ophthalmological care; however, many authors have arrived at the conclusion that photodynamic therapy (PDT) plays a major role in solving this difficult problem. Fifteen (18 eyes) patients, including 8 (8 eyes) patients diagnosed as having senile macular degeneration and SNM and 7 (10 eyes) patients diagnosed as having complicated high-grade myopia, and 3 were diagnosed as having bilateral SNM. The Russian agent Photosense, 0.05 mg/kg, was used as a photosensitizer. PDT was performed on day 3 after administration of the agent according to the peak of accumulation and the maximum laser concentration gradient at a wavelength of 675 nm and a light dose of 120 J/cm2. Good functional and angiographic results may be observed after the first 3 months of a prospective controlled open-labeled study of the efficiency of PDT with Photosense; however, longer follow-ups and larger groups of patients are required to make a final assessment of this treatment.

[Initial experience with laser retinal surgery].

The authors describe 21 cases with resection of the retinal rupture valve with Nd:YAG laser impulse, performed to reduce the vitreoretinal tractions. Resection of the 'dump' rupture valve has been carried out in 10 cases, in the rest 11 the operation has been performed in the presence of a detachment of the retina. Anatomic success (detachment of the valve from the retina) has been achieved in 16 cases. The technique of the surgery is described, as are indications and contraindications to the operation.
