Summary: Diabetic Retinopathy is an eye disorder caused by high blood sugar levels in diabetes patients, which damages blood vessels in the eyes and can lead to blindness. This paper proposes a simple and effective technique for early detection of exudates and microaneurysms, which can save the patient's vision. The research uses image processing, features extraction, and machine learning to accurately predict the presence of exudates and microaneurysms and grade the severity of the disease.

Summary: The range of diseases such as diabetes, hypertension, and vascular occlusions is increasing rapidly in modern society, leading to organ damage. Among them, eye diseases have severe impacts on vision, and early detection and treatment are necessary. Existing strategies have some setbacks, so a deep learning framework has been developed in this study to improve the prediction of retinal hemorrhage.

Summary: The study compared primary rhegmatogenous retinal detachments in phakic and pseudophakic eyes, as well as the differences within phakic eyes with and without cataract. It found significant variations in presenting features between pseudophakic and phakic RD, with some similarities between phakic RD with cataract and pseudophakic RD.

Summary: In this study of 7532 PPV procedures, intracameral cefuroxime was found to be a safe and effective choice for prophylaxis against endophthalmitis, with a lower incidence compared to subconjunctival administration. There were no cases of cefuroxime toxicity identified, but it was estimated that subconjunctival administration could lead to potentially toxic vitreous drug concentrations in certain cases.

Summary: This study retrospectively analyzed data from two online datasets to assess the effect of sex and laterality on clinical features of primary RRD. The results showed a male predominance and a higher number of right eyes. Males were more commonly pseudophakic and presented with baseline posterior vitreous detachment. Females were associated with myopia, retinal holes, and isolated inferior RD. Right eyes had more foveal involvement and larger retinal tears, while left eyes were more myopic and presented with isolated nasal RD.

Summary: This study aimed to identify factors associated with anatomical outcome after vitrectomy and internal tamponade for rhegmatogenous retinal detachment. The results showed that age, location and extent of retinal breaks, density of silicone oil, and presence of proliferative vitreoretinopathy were associated with increased risk of failure, while C2F6 tamponade, cryotherapy, and 25 G vitrectomy were associated with reduced risk. The risk stratification model indicated that a large portion of patients are at low or moderate risk of failure.
