Bull's Eye Maculopathy in Near-Infrared Reflectance as An Early Sign of Hydroxychloroquine Toxicity.

Hydroxychloroquine (HCQ) ocular toxicity is rare but severe, and progression can occur even after termination of therapy. Case reports have suggested that a bull's eye maculopathy detected by near-infrared reflectance (NIR) may indicate early HCQ toxicity. This retrospective cross-sectional study evaluated patients treated with HCQ who underwent routine screening with optical coherence tomography (OCT), fundus autofluorescence (FAF) and 10-2 perimetry.

Sensitivity and specificity of MultiColor imaging in detecting proliferative diabetic retinopathy.

Purpose: To evaluate the accuracy of MultiColor imaging (MC) compared to fluorescein angiography (FA) in detecting proliferative diabetic retinopathy (PDR) and associated diabetic retinopathy features.

Methods: Fifty-nine eyes from 38 PDR patients were included. MC images were reviewed by 2 independent masked graders.

Update on Optical Coherence Tomography and Optical Coherence Tomography Angiography Imaging in Proliferative Diabetic Retinopathy.

Proliferative diabetic retinopathy (PDR) is a major cause of blindness in diabetic individuals. Optical coherence tomography (OCT) and OCT-angiography (OCTA) are noninvasive imaging techniques useful for the diagnosis and assessment of PDR. We aim to review several recent developments using OCT and discuss their present and potential future applications in the clinical setting.

Ultrasonic circular cyclocoagulation prospective safety and effectiveness study.

Purpose: To evaluate the efficacy and safety of ultrasound cycloplasty procedures (UCP) in patients with uncontrolled glaucoma.

Methods: Prospective longitudinal study with UCP was performed by EyeOP1© probe with 8 s duration on 6 or 8 sectors, according to baseline intraocular pressure (IOP). Complete ophthalmic examination was performed pre- and post-operatively at 1st day, 1st week, 1st, 3rd, 6th, 9th and 12th months.

Optical coherence tomography features of neovascularization in proliferative diabetic retinopathy: a systematic review.

Background: Diabetic retinopathy (DR) is a leading cause of blindness due to diabetic macular edema (DME) or complications of proliferative diabetic retinopathy (PDR). Optical coherence tomography (OCT) is a noninvasive imaging technique well established for DME but less used to assess neovascularization in PDR. Developments in OCT imaging and the introduction of OCT angiography (OCTA) have shown significant potential in PDR.

Transient choroidal detachment after ultrasonic circular cyclocoagulation.

Two patients with refractory glaucoma followed in our ophthalmology department registered progression on left eyes (OS) despite best practice. Best corrected visual acuity (BCVA) was 9/10 and 8/10 and intraocular pressure (IOP) was above 20 mm Hg while under maximal hypotensive therapy. The procedure was performed under retrobulbar anaesthesia with second-generation EyeOp1probes.

Pigmented paravenous retinochoroidal atrophy associated with unilateral cystoid macular oedema.

A 65-year-old man was referred to our department with complaints of blurred vision in the left eye. Funduscopic examination revealed areas of retinochoroidal atrophy along the retinal veins bilaterally and bone spicule pigmentation along the nasal and superior temporal venous branches, as well as macular oedema in the left eye. Fluorescein angiography, visual field test, optical coherence tomography and electrophysiological examination were performed, and results were compatible with the diagnosis of pigmented paravenous retinochoroidal atrophy (PPRCA).
