A clinical case of a surgical treatment of complicated cataract in a patient with Hall–Hittner syndrome

Background: Variants of the CHD7 gene found in the OMIM 608892 genomic material are present in 83–95% of patients suffering from the CHARGE syndrome. The aim of this report is to evaluate the clinical and functional results of cataract phacoemulsification with implantation of a toric intraocular lens in a patient with a very rare pathology — Hall–Hittner syndrome. Clinical case description: Under observation was patient V., who successfully underwent cataract phacoemulsification on the right eye with implantation of an intraocular lens for complicated cataract against the background of combined congenital eye pathology confirmed by the diagnostic data before and after the surgery. The optimal visual functions were reached after the successful surgical treatment. The patient was subjectively satisfied with the restored visual functions in the right eye. Conclusion: The clinical case demonstrates a successful implementation of cataract phacoemulsification with implantation of a toric intraocular lens in a patient diagnosed with complicated cataract against the background of combined congenital eye pathology, which suggests the possibility of a surgical treatment for such patients.
