Because of complications and side effects, conventional laser therapy has taken a back seat to drugs in the treatment of macular diseases. Despite this, research on new laser modalities remains active. In particular, various approaches are being pursued to preserve and improve retinal structure and function. These include micropulsing, various exposure titration algorithms, and real-time temperature feedback control of short-pulse continuous wave lasers, and ultra-short-pulse nanosecond lasers. Some of these approaches are at the preclinical stage of development, whereas others are available for clinical use. Cell biology is providing important insights into the mechanisms of action of retinal laser treatment. We outline the technological bases of current laser platforms, their basic science, therapeutic concepts, clinical experience, and future directions for retinal laser treatment.

Our current prospective cross-sectional study aimed to investigate the effect of anti-vascular endothelial growth factor (VEGF) drugs used in the treatment of retinopathy of prematurity on retinal maturation and persistent avascular retina (PAR). Retinal imaging was performed with Optos confocal laser ophthalmoscopy for 100 patients aged 4 to 8 years who were screened and treated for retinopathy of prematurity (ROP) during the neonatal period. The ROP examination findings (stage and zone) and treatment history (age in weeks at time of treatment and anti-VEGF drug used) from the neonatal period were reviewed.

Background: This study investigated the association between photoreceptor structural restoration and visual function outcomes in patients undergoing surgery for closed macular holes (MHs). Using adaptive optics scanning laser ophthalmoscopy (AOSLO) and microperimetry, we aimed to provide a more detailed understanding of photoreceptor recovery and visual improvement in closed MHs.
Methods: We conducted a retrospective observational study of 31 eyes of 28 patients who underwent vitrectomy with internal limiting membrane (ILM) peeling to treat idiopathic MHs.

Three-dimensional bioprinting (3DP) is transforming the field of regenerative medicine by enabling the precise fabrication of complex tissues, including the retina, a highly specialized and anatomically complex tissue. This review provides an overview of 3DP's principles, its multi-step process, and various bioprinting techniques, such as extrusion-, droplet-, and laser-based methods. Within the scope of biomimicry and biomimetics, emphasis is placed on how 3DP potentially enables the recreation of the retina's natural cellular environment, structural complexity, and biomechanical properties.

Purpose: To demonstrate the response of a juxtapapillary retinal hemangioblastoma (JRH) to belzutifan in a patient with Von-Hippel-Lindau syndrome (VHL).
Methods: This case report includes fundus photography and optical coherence tomography to compare a juxtapapillary retinal hemangioblastoma (JRH) before and 24 months after treatment with belzutifan.
Results: An 18-year-old woman with VHL was diagnosed with a juxtapapillary retinal hemangioblastoma (JRH) at age 13.

Diabetes mellitus (DM) is a chronic metabolic non-communicable disease with the ability to cause serious microvascular and macrovascular complications throughout the body, including in the eye. Diabetic retinopathy (DR), present in one-third of patients with diabetes, is a vision-threatening complication caused by uncontrolled diabetes, which greatly affects the retinal blood vessels and the light-sensitive inner retina, eventually leading to blindness. Several epidemiological studies elucidate that DR can vary by age of onset, duration, types of diabetes, and ethnicity.
