Introduction: Solitary uveal lesions confer a diagnostic challenge to ophthalmologists. Uveitic lesions most abundantly appear amelanotic and commonly involve the choroid. Most amelanotic choroidal lesions are either neoplastic or inflammatory in origin.

Methods: This cohort study included patients who underwent surgical repair SB group and PPV group for chronic retinal detachment during 2014-2018 at the King Khalid Eye Specialist Hospital, Riyadh. The anatomical and functional success rate at 12 months after surgery was compared in two groups.
Background/aims: To report visual outcomes, survival outcomes and complications following episcleral brachytherapy (EB) for retinoblastoma.
Methods: Retrospective review of retinoblastoma cases treated with EB in a single institution. Survival outcomes were analysed using the Kaplan-Meier method.
Cotton leaf curl virus (CLCuV) disease is one of the major limiting factors in cotton production, particularly in widely cultivated varieties that are susceptible to attack by this virus. Several approaches have been employed to explore putative resistance genes in another cotton species, . However, the exact mechanisms conferring disease resistance in cotton are still unknown.

Purpose: To report the effectiveness of Goniosynechialysis (GSL) treating elevated intraocular pressure (IOP) in an aphakic eye with peripheral anterior synechiae (PAS) formation after vitrectomy.
Observations: A 39-year-old gentleman with history of lamellar keratoplasty for corneal ectasia and blunt trauma to the right eye necessitating vitrectomy and lensectomy presented to our glaucoma unit with a secondary angle closure and an IOP of 50 mmHg. This was successfully treated with GSL and one year after surgery, the patient maintains a normal IOP without the use of medication.
Humic substances (HSs) have considerable effects on soil fertility and crop productivity owing to their unique physiochemical and biochemical properties, and play a vital role in establishing biotic and abiotic interactions within the plant rhizosphere. A comprehensive understanding of the mode of action and tissue distribution of HS is, however, required, as this knowledge could be useful for devising advanced rhizospheric management practices. These substances trigger various molecular processes in plant cells, and can strengthen the plant's tolerance to various kinds of abiotic stresses.

Methods: Records from a single institution were retrospectively reviewed from January 1997 to December 2015. The mean follow-up duration was 38 months (range 0-194).
Purpose: To investigate the outcomes of pars plana vitrectomy (PPV) for chronic diabetic traction macular detachment (CTMD).
Methods: Ninety-six eyes that underwent PPV for CTMD of at least 6 months duration were retrospectively analyzed. Retinal reattachment rate, final vision, and prognostic factors for poor visual outcome were the main outcome measures.
Purpose: To compare the rates of tumour recurrence following episcleral brachytherapy for uveal melanoma before and after implementation of intraoperative echographic confirmation of plaque placement.
Materials And Methods: All patients with primary single ciliary body or choroidal melanoma treated with iodine-125 or ruthenium-106 plaque brachytherapy between 1 January 2004 and 30 December 2013 were included. Exclusion criteria were patients with previous radiation treatment and patients who received adjuvant transpupillary thermotherapy.
A 24-year-old healthy male presented with a chief complaint of blurred vision in the right eye for 1-week. Fundus examination indicated right exudative retinal detachment and choroidal ischemia. The patient responded well to anti-toxoplasmosis medications and steroids.

In the vasopressin-induced angina model, oral administration of allopurinol in dose of 10 mg/kg revealed remarkably analogous effects in comparison with amlodipine such as dose-dependent suppression of vasopressin-triggered time, duration and severity of ST depression. In addition, allopurinol produced dose dependent suppression of plasma Malondialdehyde (MDA) level, systolic blood pressure, cardiac contractility and cardiac oxygen consumption; while in contrast, amlodipine minimally suppressed the elevation of plasma MDA level.
