Obstructive Sleep Apnea and the Retina: A Review.

J Clin Sleep Med 2021 May 3. Epub 2021 May 3.

Department of Ophthalmology, Universidade Federal de São Paulo - EPM - São Paulo (SP), Brazil.

None: This review's objective was to synthesize the literature on the repercussions of obstructive sleep apnea (OSA) in the retinal vascular system. Two independent investigators conducted a search using the MEDLINE/PubMed database using the following terms: sleep apnea syndrome; obstructive sleep apnea; retina; vascular tortuosity; central serous chorioretinopathy; diabetes mellitus; and subfoveal choroidal thickness. OSA patients present increased vascular tortuosity compared to non-OSA patients, decreased parafoveal and peripapillary vessel density, and increased retinal vein occlusion incidence. Read More

Incidence of Paradoxical Neurosensory Detachment in Diabetic Eyes Undergoing Hemodialysis for End-Stage Renal Disease.

Cureus 2021 Apr 28;13(4):e14739. Epub 2021 Apr 28.

Anterior Segment & Cataract, Dr. Agarwal's Eye Hospital (Kolkata Branch at Peerless Hospital & B K Roy Research Centre), Kolkata, IND.

Introduction Ocular fluid dynamics are known to improve during hemodialysis, and the improvement of uremia after dialysis may lead to osmotic pressure changes in the retina, which eventually affect retinal edema. Recent studies using optical coherence tomography (OCT) to assess the effect of hemodialysis on macular thickness have shown variable results with a majority of them finding a decrease in retinal thickness. Paradoxical neurosensory retinal detachment (NSD) may be defined as the accumulation of subretinal fluid under the macula in patients who are on continuous HD. Read More

From the Hypotheses to Clinical Evidence in Retinal Therapy.

J Ophthalmic Vis Res 2021 Apr-Jun;16(2):287-290. Epub 2021 Apr 29.

Wilmer Eye Institute, Johns Hopkins University School of Medicine, Baltimore, MD.

The off-label, therapeutic use of intravitreal bevacizumab (IVB) in vascular retinal diseases such as diabetic macular edema and proliferative diabetic retinopathy (PDR) has increased significantly due to its ability to reduce retinal neovascularization and slow progression of disease. Here, we will review the literature and investigative developments on the use of IVB as a preoperative adjuvant to vitrectomy in severe PDR, specifically focusing on its ability to reduce intra- and postoperative complications and its risk for progression or development of traction retinal detachment. In particular, this review will highlight the natural progression of evidence from case series and observations to prospective, randomized clinical trials. Read More
