Purpose. To present a rare clinical case of bilateral Coates retinitis in a 5-year-old girl. Material and methods. A clinical case of a 5-year-old girl with rare Coat's retinitis in both eyes is described. The disease occurred abruptly: the child's parents noted the appearance of leukocoria in the right eye. After the examination Coates ' retinitis was diagnosed. At the time of examination in the clinic, there was a retinal detachment in the right eye, the surgical treatment was performed: lensvitrshvartectomy, plastic surgery of the anterior chamber, with the melting of the retina with perfluoroorganic compounds, drainage of subretinalfluid, endolaser coagulation on the right eye. A month after the first symptoms appeared in the right eye, the patient complained of decreased vision in the left eye. Examination on the pediatric retinal camera showed an increase in vascular activity in the left eye, and signs of Coats' retinitis were revealed. Results. As a therapy for this disease, the patient was twice injected intravitreally inhibitor of vascular endothelial growth factor (VEGF inhibitor) into the left eye with positive dynamics noted as a decrease in the activity of retinal vessels and leveling of the exudative component, as well as with an increase in visual acuity in the left eye. Conclusion. This clinical case demonstrates that intravitreal administration of inhibitor VEGF with traditional methods of treatment can be used as a treatment for patients with Coates retinitis. Key words: Coat's retinitis, Coats' disease, vascular endothelial growth factor inhibitor, aflibercept, intravitreal injection, anti-VEGF, retinal detachment.

The objective of this study was to measure the vascular endothelial growth factor (VEGF) levels in dogs diagnosed with chronic superficial keratitis (CSK). The study was performed on 25 German shepherds (14 males and 11 females, aged between 3 and 11 years). The VEGF levels were determined in blood serum using commercially available enzyme-linked immunosorbent assay (ELISA; Quantikine Canine VEGF Immunoassay, R&D Systems). The test group of affected German shepherds was subdivided into two subgroups, based on the area of corneal neovascularisation. The first subgroup (9 patients) comprised dogs with neovascularisation observed in 1 to 2 quadrants of the right and left cornea, while the second subgroup (16 patients) comprised dogs with neovascularisation observed in 3 to 4 quadrants of the right and left cornea. The control group comprised 12 clinically healthy German shepherds (7 males and 5 females, aged between 3 and 9 years). The results were then statistically analysed by the Mann-Whitney test. The study indicated that the median serum VEGF concentration in healthy dogs was 14.9 pg/mL. The VEGF level observed in sick German shepherds was elevated (19.5 pg/mL) as compared to the values found in healthy dogs; however, a statistically significant increase in VEGF concentration, as compared to the values observed in healthy dogs, was only noted in the first subgroup, where the median VEGF concentration was 22.0 pg/mL. Elevated serum VEGF concentration was observed in German shepherds diagnosed with CSK. A statistically significant increase in VEGF levels was observed in dogs in the first stage of the disease, i.e. the early stage of neovascularisation.

Purpose: To report a follow up of early intravitreal anti-vascular endothelial growth factor (VEGF) antibody treatment in a patient with maculopathy after accidental exposure to a high-powered cosmetic Nd:YAG laser.Case summary: A 36-year-old female patient visited our clinic with decreased visual acuity in the right eye after accidental exposure to a high-powered cosmetic Nd:YAG laser. The best-corrected visual acuity of the right eye was 0.1 and subretinal hemorrhage on the foveal area was observed during fundus examination. Optical coherence tomography revealed serous retinal detachment with hyperreflective disruption of the ellipsoid zone and retinal pigment epithelium-Bruch’s membrane complex. Intravitreal bevacizumab (Avastin®, 1.25 mg/0.05 mL; Roche Korea, Seoul, Korea) injections were performed three times. Visual acuity was unchanged at 6 months after the first visit. However, complete resolution of the subretinal hemorrhage was observed and there were no signs of secondary choroidal neovascularization or recurrence of choroidal hemorrhage.Conclusions: Early anti-VEGF antibody treatment in a patient with subfoveal hemorrhage and choroidal rupture after high-powered cosmetic Nd:YAG laser exposure improved morphology and prevented secondary choroidal neovascularization.
