Clinical analysis of vitreous haemorrhage associated with retinal tears

Abstract

AIM: To study the clinical characteristics of vitreous hemorrhage associated with retinal tears, so as to provide suggestions for early intervention and improving the prognosis of patients.METHODS: This was a retrospective study. Totally 105 patients(105 eyes)with vitreous haemorrhage associated with retinal tears treated at our hospital from December 2016 to December 2018 including 54 males and 51 females, of who the clinical characters, therapeutic effcet and prognostic facors were retrospectively analyzed.RESULTS: Among the 105 eyes(151 retinal tears), 82 tears were located in the superotemporal area(54.3%), 28 tears were located in the superonasal area(18.5%), 27 tears were located in the inferior temporal area(17.9%), and 14 tears were located in the inferior nasal area(9.3%). The shape of the retinal tears was mostly horseshoe(77.5%). The diameter of the tear was between 1/8-4 papillary diameter(PD), most commonly is 1 PD. Seventy-six patients(72.4%)had visual acuity better than or equal to their preoperative vision. There was no significant difference in corrected visual acuity pre-and postoperative(P>0.05), and there was no statistically significant improvement in visual acuity between the buckling procedure group and the vitrectomy group(P>0.05).CONCLUSION: Retinal tear is an important cause of vitreous haemorrhage. Retinal tears were mostly located in the superotemporal area with horseshoe shape. A comprehensive understanding of the clinical characteristics of rhegmatogenous vitreous haemorrhage helps to detect tears early and avoid serious complications.Patients had preoperative best corrected visual acuity(BCVA)(LogMAR)less than 1.6 and light perception less than 1 m, have poor postoperative vision, as do patients with retinal detachment involving the macula especially along with proliferative vitreoretinopathy(PVR).
