Eligibility

Inclusion criteria

Inclusion criteria: 1. Diagnosis of Diabetic Macular Edema (DME): Confirmed by clinical examination and optical coherence tomography (OCT). 2. Previous Anti-VEGF Therapy: Patients who have received prior treatment with conventional anti-VEGF agents such as ranibizumab, aflibercept, or bevacizumab. 3. Indication for Brolucizumab Therapy: Senior retina specialist to decide for eyes of patients requiring a switch to brolucizumab due to suboptimal response, recurrence, or tolerance issues with previous anti-VEGF therapy(refractory DME). 4. Age: Adults aged 18 years and older. 5. Ability to Provide Consent: Patients willing to participate and provide written informed consent.

Exclusion criteria

Exclusion criteria: 1. Prior Brolucizumab Treatment: Patients who have already received brolucizumab for same or any other ocular indication. 2. Recent Intraocular Surgery: Any ocular surgery, including cataract surgery, within the last 3 months. 3. Active Ocular Infections or Inflammation: Presence of endophthalmitis, uveitis, or scleritis in the study eye. 4. Advance Proliferative Diabetic Retinopathy (PDR): Severe pathologies requiring vitrectomy eg. Macular tractional detachments 5. Significant Media Opacities: Presence of dense cataracts, vitreous hemorrhage, or other conditions affecting accurate OCT imaging. 6. Uncontrolled Intraocular Pressure (IOP): Patients with IOP more than 25 mmHg despite maximum medical treatment. 7. Pregnancy or Breastfeeding: Women who are pregnant, planning pregnancy, or currently breastfeeding. 8. Hypersensitivity to Brolucizumab or its Components: Known allergy to the drug or any of its excipients. 9. Patients not coming for follow up are considered as drop outs & will be excluded from the study.

Design outcomes

Primary

MeasureTime frame
1. Best Corrected Visual Acuity in LogMAR units 2. Central Macular Thickness in micrometers calculated using OCT ruler tool 3. Macular Volume in millimeter cube using OCT valuesTimepoint: We will look for these parameters at 6 different visits: 1. baseline, just before injection of Intravitreal anti - VEGF injection 2. 2 weeks after Intravitreal anti-VEGF injection 3. 6 weeks after Intravitreal anti- VEGF injection 4. before injecting Intravitreal brolucizumab injection 5. 2 weeks after Intravitreal brolucizumab injection 6. 6 weeks after Intravitreal brolucizumab injection

Secondary

MeasureTime frame
Number and percentage (%) of eyes required repeat intravitreal injection in:Timepoint: a) 6 weeks b) 10 weeks c) 14 weeks d) 18 weeks ;Number of eyes which did not require repeat intravitreal brolucizumabTimepoint: up to 18 weeks;Evaluate the occurrence of any adverse effects i) Anterior chamber cells & flare ii) Subconjunctival haemorrhage iii) Hyperaemia iv) Endophthalmitis v) Vascular occlusion vi) Vascular sheathing vii) Vitritis Timepoint: whole study period
