Peculiarities of the Clinical Picture, Pathogenesis and Drug Treatment of Secondary Phacogenic Glaucoma

intraocular pressure, glaucoma, cataract, lens, luxationAbstract
Pathologies of the lens often lead to increased intraocular pressure and the development of secondary glaucoma. The article presents a description of the clinical picture and pathogenetic aspects of the development of various forms of secondary phacogenic glaucoma: phacotopic, phacomorphic and phacolytic. A scheme of intensive drug therapy aimed at reducing intraocular pressure and neuroprotection of the retina is proposed. Based on the results of the study, an assessment of the effectiveness of hypotensive treatment was made, as well as the possibility of long-term drug control of ophthalmotonus against the background of lens pathologies. Ophthalmological examinations were performed in daylight, artificial light, and in the dark. Results and discussion. Studying the risk factors for secondary glaucoma, it was found that in 55 out of 142 patients (39% of cases), the development of secondary glaucoma was associated with lens pathologies (phacogenic glaucoma): luxation or subluxation of the lens, swelling cataract, lysis of hypermature cataract. Diagnostic criteria and clinical picture of glaucoma of phacogenic etiology were studied in 55 patients (68 eyes – 100%). Average IOP values during tonometry were 37.13 ± 4.45 mm Hg. The study revealed that in 42 out of 55 patients (42 eyes – 76.4% of cases) secondary glaucoma against the background of lens pathologies was noted unilaterally. In 13 patients (26 eyes – 23.6% of cases) phacogenic secondary glaucoma was noted bilaterally.
