SummaryBackgroundAcute retinal necrosis (ARN) is characterized by the triad of acute vitritis, peripheral necrotizing retinitis and vasculitis.Case ReportWe report a case of 54-year-old woman with bilateral acute retinal necrosis associated with neuroinfection. Her past medical history included renal transplantation, hypertension and aortic stenosis. Observational case report: Diagnostic investigations included biochemical tests, lumbar puncture, eye ultrasonography and MRI of the brain.Anti-HSV IgG antibody titers were elevated in the blood and cerebrospinal fluid. In MRI T2-mode, inflammatory changes were found in the white matter of the right hemisphere. The patient was treated with systemic acyclovir, itraconazole, metronidazole and ciprofloxacin for 3 weeks. Retinal detachment was observed in both eyes.ConclusionsAcute retinal necrosis can be the single manifestation of herpes virus reactivation in patients after organ transplantation.

The aim of the article is to present the developed technique to measure the degree of neovascularisation of the cornea image in visible light. The study used an image sensor attached to a slit lamp. The proposed technique consists in performing segmentation of the color image to enhance blood vessels and setting values of the degree of cornea neovascularisation. Comparison of the indicator before and after treatment of the cornea can objectively assess the eectiveness of the adopted method of treatment.

A case report of exposure and neurotrophic keratopathy after acoustic neuroma surgery resulting in perforation if not managed appropriately and timely is presented. Sclerokeratoplasty on 360 degrees may be an effective treatment method of corneal perforation in complete anaesthetic cornea when the standard penetrating keratoplasty failed. At a 12-month follow-up, the patient is doing well. UCVA is 0.5, the IOP is normal, and the graft remains clear. Systemic immunosuppression is the main disadvantage of this method. Further investigation is needed to assess the effectiveness and safety of this method.
