Macular vessel density before and after panretinal photocoagulation in patients with proliferative diabetic retinopathy.

Introduction: Diabetic retinopathy (DR) is microangiopathy causing ischemia leading to proliferative diabetic retinopathy and macular edema. Panretinal photocoagulation (PRP) reverses the ischemia leading to regression of neovessels. Most previous studies showed the large vessel effects of PRP, while optical coherence tomography angiography (OCTA) allowed noninvasive quantification of microvascular retinal changes.

Combined endophthalmitis and orbital cellulitis in patients with corona virus disease (COVID-19).

Purpose: To document the presentation of unilateral combined endophthalmitis and orbital cellulitis in patients with COVID-19 infection and study their prognosis.

Patients And Methods: This interventional case series study included 9 patients referred to the Ophthalmology Department, Minia University Hospital with unilateral combined endophthalmitis and orbital cellulitis between April 2020 and March 2021. In addition to the COVID-19 work-up, all patients were subjected to full ophthalmological evaluation and managed according to their ophthalmic and systemic disease.
