Background: Pituitary tumors are adenomas of a region of the sella turcica which can produce compression of the anterior visual pathway.
Patients And Methods: Besides clinical signs of visual improvement such as enhanced visual acuity and visual field, the use of electroophthalmological methods can help monitor patients after neurosurgery.
Results: The N75 P100 amplitude of the p-VEP has proven to be the most sensitive marker for measuring-improvements after surgery. This amplitude significantly increased, whereas latency time, visual acuity and visual field showed no statistically significant changes after surgery.
Conclusions: The p-VEP is an important tool in treating patients with compression of the visual pathway.

Ophthalmology, Faculty of Medicine, Alanya Alaaddin Keykubat University, Antalya, TUR.
Purpose This study evaluated the efficacy of oral melatonin therapy for visual acuity and retinal and choroidal structures in patients with chronic central serous chorioretinopathy (CSCR). Methods Fourteen patients with CSCR were included; eight received oral melatonin (3 mg nightly), and six formed the control group. Best-corrected visual acuity (BCVA), central macular thickness (CMT), central choroidal thickness (CCT), and choroidal vascularity index (CVI) were assessed at baseline and after one month.

Optic nerve disorders significantly contribute to visual impairment with irreversible visual deficits. Current treatments have limited efficacy in resolving chronic visual deficits, necessitating novel therapeutic strategies. Neurorehabilitation techniques, including repetitive transorbital alternating current stimulation (rtACS), have emerged as promising approaches to restore lost visual function through the ability to modulate brain activity.

Background: Age-related macular degeneration (AMD) is a prevalent cause of irreversible vision loss worldwide, particularly among the elderly population. Two forms of late AMD are described: neovascular AMD (nAMD), characterized by abnormal choroidal blood vessel growth, and atrophic (dry) AMD, involving retinal cell degeneration. Intravitreal anti-vascular endothelial growth factor (anti-VEGF) agents have transformed nAMD treatment, with Brolucizumab emerging as a promising therapy.

Purpose: Systemic sclerosis (SSc) affects blood vessels, internal organs, and skin. In ophthalmology, SSc impacts the choroid. The choroidal vascularity index (CVI) measures the vascular component of the choroid and may serve as a biomarker for the disease staging and prognosis.

Coats disease is a rare abnormality characterized with retinal telangiectasia and aneurysms with retinal exudation, most often seen in young males and usually affecting only one eye. A 12-year-old boy came in with a three-month history of vision loss and pain in his right eye, alongside progressively worsening blurred vision over the last year. His visual acuity was reduced to only light perception in the right eye, while his left eye maintained 5/5 vision.
