AIM:To investigate the risk factors of high intraocular pressure after cataract surgery for phacolytic glaucoma(PLG).

METHODS: The clinical data of 148 PLG patients(148 eyes)who underwent cataract surgery were analyzed retrospectively. According to the occurrence of postoperative high intraocular pressure, the patients were divided into non-high intraocular pressure group and high intraocular pressure group. Logistic regression analysis was used to evaluate the risk factors of high intraocular pressure after cataract surgery in PLG patients. Nomogram model was constructed, whose predictive ability was evaluated by receiver operating characteristic curve(ROC).

RESULTS: There was no significant difference in age, gender, BMI, cataract lens nucleus grade, combined with hypertension, and surgical methods between two groups(P>0.05); the proportion of diabetes, high myopia, preoperative uveitis, preoperative ocular trauma and intraoperative complications in high intraocular pressure group were higher than those of non-high intraocular pressure group, with the difference was statistically significant(P<0.05). Logistic regression analysis showed that diabetes, high myopia, preoperative uveitis, preoperative ocular trauma and intraoperative complications were independent influencing factors for high intraocular pressure after cataract surgery in PLG patients. The nomogram model constructed in this study had good fitting effect, and the area under the ROC curve was 0.906(0.890-0.921), indicating that it had strong predictive ability.

CONCLUSION: PLG patients with intraoperative complications, preoperative uveitis, ocular trauma, diabetes and high myopia had higher risk of high intraocular pressure after cataract surgery. Clinical doctors should pay more attention to these patients in order to improve the treatment prognosis.
