Abstract Details



Purpose:

To evaluate the risk factors and identify the prognosis and 1 year outcomes for patients diagnosed with ischaemic CRVO. This was a retrospective study of 30 patients diagnosed with ischaemic CRVO between 01/04/15 and 01/04/16

Setting:

The audit was carried out in the ophthalmology department of a busy teaching hospital in the UK.

Methods:

Patients were ascertained from the departmental electronic database as those patients diagnosed with CRVO requiring Pan Retinal photocoagulation with at least 1 year follow up. Data were collected from patient records on gender, age, risk factors, visual acuity, IOP, subsequent surgery and medications prescribed.

Results:

30 patients (14M and 16F) with ischaemic CRVO were analysed. The mean age was 71.13 years old and the major risk factor HTN (73% of all patients). 40% of the patients had a history of DM and glaucoma and 26% of dyslipidaemia. Presenting visual acuity was a significant prognostic factor for the final visual outcome. 50% of the patients presented with visual acuity of less than CF (56% after 1 year) and only 30% had visual acuity better than 6/36 (33% after 1 year). In terms of management all patients underwent PRP and 60% of them received 2.6 mean number of anti-VEGF injections (83% of which was AvastinĀ®). 10% of the patients developed glaucoma within the first year, which was controlled on drops and systemic diamox. From the 12 patients that already had a history of glaucoma, 5 (42%) required glaucoma intervention (4 cyclodiode and 1 BVT).

Conclusions:

Hypertension is considered one of the major risk factors for ischaemic CRVO. The prognosis overall was poor with only 30% of the patients achieving visual acuity better than 6/36 after 1 year. Reduced presenting visual acuity was related to guarded longterm prognosis.
