Choroidal vascularity index in leptochoroid: A comparative analysis between reticular pseudodrusen and high myopia

Purpose. To conduct a comparative analysis of the anatomical parameters of the eyeball in children with ametropia, congenital glaucoma, aphakia and artiphakia.Material and methods. The study involved 73 patients (146 eyes) aged 5 to 12 years with ametropia, congenital glaucoma, aphakia and artiphakia and was carried out on an ultrasonic device STRONG 6000 T in the A-scan mode with the 10 MHz sensor set for three points.Results. A significant increase in the size of axial length of the eyeball in moderate and high myopia and in the vertical size in high myopia were revealed. In high hyperopia, sagittal dimensions were reduced while the transverse dimensions were a bit greater than the sagittal ones. In far-advanced stage of congenital glaucoma, a significant increase in eyeball dimensions was noted both in the axial direction and in the transverse — horizontal direction. No significant differences in sagittal and transverse dimensions were noted in aphakia and artiphakia. Conclusion. For a comprehensive assessment of the clinical course of the disease, in particular as concerns the condition of the fibrous capsule of the eye in children with ametropia, congenital glaucoma, aphakia and artiphakia, echobiometric indicators characterizing sagittal and transverse (vertical and horizontal) sizes of the eyeball should be taken into account.

Purpose. Comparative analysis of the achieved clinical refraction and the state of visual functions in patients with high myopia after implantation of multifocal and phakic intraocular lenses (IOL), subjective patients satisfaction of the quality of vision when working at close range. Material and methods. The clinical material consisted of 23 patients (46 eyes) with high myopia. 1st group – 10 people (20 eyes), who underwent phacoemulsification with implantation phakic and toric phakic IOLs (IPSL V 2.0) in both eyes, 2nd group – 13 people (26 eyes) – with implantation multifocal and multifocal toric IOLs (Alcon, USA) in both eyes. Uncorrected visual acuity (UCVA) at various distances and subjective patients satisfaction of visual functions using a standard questionnaire were investigated. Results. UCVA indices for the three distances turned out to be comparably high in both groups and did not reveal a statistically significant difference. But for long distance 12 months after the operation, the average UCVA index turned out to be statistically significantly higher in the 2nd group, amounting to 0.65 (0.6; 1) versus 0.5 (0.5; 0.6) in the 1st group. According to the result of the total calculation of the scores of the questionnaire, there was no statistical difference in the obtained indicators; p=0.13. Conclusion. Comparative analysis showed that both methods of IOL implantation in patients with high myopia made it possible to achieve high indicators of visual functions and high satisfaction of quality of vision at any distance. Key words: high myopia, IPCL, phakic IOL, multifocal IOL.
