Purpose: To evaluate clinical efficacy of combined sulphur hexafluoride (SF6) gas tamponade and laser photocoagulation for optic disc pit maculopathy (ODPM).
Methods: Eleven eyes of nine patients with optic disc pit maculopathy were treated with intravitreal injection of 0.6 ml 100% sulphur hexafluoride (SF6) combined with laser photocoagulation treatment. Patients were followed up for a mean of 28.54 months (range of 14-57 months) after treatment. The anatomical success was shown by optical coherence tomography (OCT) and the functional outcome was judged by best corrected visual acuity.
Results: Treatment with SF6 gas tamponade followed by laser photocoagulation in OPDM patients resulted in resolution of subretinal fluid (SRF) in 82% of eyes after single injection. Repeated injection was needed in two eyes to achieve resolution of SRF. Visual acuity improved significantly from a mean of 0.83 ± 0.14 logMAR preoperatively to a mean of 0.26 ± 0.11 logMAR postoperatively. Visual acuity stayed stable throughout the follow-up period.
Conclusions: SF6 gas tamponade combined with laser photocoagulation represents simple, effective, minimally invasive treatment option for ODPM without vitreomacular traction. Repeated injection was required in some patients.

Purpose: To describe two cases of pediatric patients with Coats disease who developed nerve fiber layer (NFL) schisis.
Methods: Observational case series.
Results: Two male pediatric patients, ages 2 and 14, who were being treated for Coats disease were found to have NFL schisis on optical coherence tomography.

Current treatments for retinal disorders are anti-angiogenic agents, laser photocoagulation, and photodynamic therapies. These conventional treatments focus on reducing abnormal blood vessel formation in the retina, which, in a low-oxygen environment, can lead to harmful proliferation of endothelial cells. This results in dysfunctional, leaky blood vessels that cause retinal edema, hemorrhage, and vision loss.

Introduction: Although associated with respiratory morbidity, elective endotracheal intubation (ETI) for laser photocoagulation for retinopathy of prematurity (ROP) is the standard practice at our institution, with 100% of patients undergoing preoperation ETI. To mitigate this risk, we strove to reduce the percentage of infants intubated for laser photocoagulation by 30% by June 2022.
Methods: We assembled a multidisciplinary team and implemented a deep sedation guideline utilizing dexmedetomidine, fentanyl, and midazolam with noninvasive ventilation support for laser photocoagulation in January 2020.

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.

Retinopathy of prematurity (ROP) remains a significant health care concern in neonatal care as advances in neonatal intensive practices have improved the survival rates of premature infants. The management and screening of ROP have evolved significantly, with notable trends and advancements aimed at improving outcomes. The use of intravitreal antivascular endothelial growth factor injections has emerged as a prominent initial treatment for ROP in addition to laser photocoagulation.
