Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to to evaluate the changes in retinal microvasculature secondary to intra-ocular pressure changes post intra-vitreal injection in patients with diabetic macular oedema highlighting the effect of prior anterior chamber paracentesis on such changes if present .

The main question\[s\]it aims to answer are:

•\[is there any effect of post intra-vitreal injection IOP spikes on retinal microvasculature?\] •\[is there any effect of Prior Anterior Chamber Paracentesis?\] Participants in group A will be subjected to an identified approved treatment( intra-vitreal injection)\& Participants in group B will be subjected to a prior ACP with the intra-vitreal injection . \]

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Group A

Patients with eyes with non ischemic diffuse center involving DME will be assigned to receive IVI of ranibizumab without Anterior Chamber Paracentesis.

Group Type ACTIVE_COMPARATOR

intra-vitreal injection of Ranibizumab

Intervention Type DRUG

The intravitreal injection will be performed with ranibizumab (0.5 mg/0.05 mL through a 27-gauge needle that will be inserted into the sclera 3.5 mm from the corneal limbus in pseudophakic patients, and 4 mm in phakic patients.

Group B

Patients with eyes with non ischemic diffuse center involving DME will be assigned to receive IVI of ranibizumab with Anterior Chamber Paracentesis.

Group Type ACTIVE_COMPARATOR

intra-vitreal injection of Ranibizumab

Intervention Type DRUG

The intravitreal injection will be performed with ranibizumab (0.5 mg/0.05 mL through a 27-gauge needle that will be inserted into the sclera 3.5 mm from the corneal limbus in pseudophakic patients, and 4 mm in phakic patients.

anterior chamber paracentesis

Intervention Type PROCEDURE

A 27-gauge needle on a 1-mL syringe will be inserted into the anterior chamber of the eye, and approximately 0.05 mL of aqueous humor will be withdrawn.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patients with diabetes mellitus type II.
* Patients with visual acuity \> 0.1, able to fixate and with clear visual media.
* Patients with eyes with non ischemic diffuse center involving DME were randomly assigned to receive IVI of ranibizumab either without (group A) or with (group B) ACP.

Exclusion Criteria

* Age under 40 years.
* Poorly controlled diabetics (HbA1C greater than 9.0%)
* Proliferative diabetic retinopathy.

* History of glaucoma.
* Tilted disc and optic disc anomalies.
* One-eyed patients.
* Usage of systemic or topical corticosteroids.
* Patients with a history of intraocular surgery other than cataract surgery.
* Systemc diseases rather than hypertension and diabetes mellitus.
* Corneal opacities that might hinder acquisition of good quality OCT images.
