Intraocular pressure fluctuation following intravitreal dexamethasone implant and incidence of secondary ocular hypertension: a Zambian perspective.

Introduction: to evaluate the effect of dexamethasone biodegradable implant (DEX-I), on intraocular pressure (IOP), to determine the incidence of secondary ocular hypertension (OHT) and to analyze the IOP changes as per the treatment indication in Zambian cohort.

Methods: retrospective consecutive case series of patients receiving one DEX-I between January 2016 and September 2018 with a minimum follow-up of four months in a tertiary care centre in Zambia. The IOP was recorded before the injection and at 1 week, 1, 2, 3 and 4 month after the injection.

Incidence of Paradoxical Neurosensory Detachment in Diabetic Eyes Undergoing Hemodialysis for End-Stage Renal Disease.

Introduction Ocular fluid dynamics are known to improve during hemodialysis, and the improvement of uremia after dialysis may lead to osmotic pressure changes in the retina, which eventually affect retinal edema. Recent studies using optical coherence tomography (OCT) to assess the effect of hemodialysis on macular thickness have shown variable results with a majority of them finding a decrease in retinal thickness. Paradoxical neurosensory retinal detachment (NSD) may be defined as the accumulation of subretinal fluid under the macula in patients who are on continuous HD.

Intravitreal dexamethasone implant with retinal photocoagulation for adult-onset Coats' disease.

Purpose: To report a case of adult-onset Coats' disease with secondary retinal vasoproliferative tumor managed with dexamethasone intravitreal implant and retinal photocoagulation.

Methods: Case study.

Results: A 41-year-old female with counting finger vision was diagnosed with Coats' disease with secondary retinal vasoproliferative tumor in right eye.

Secondary Angle-Closure Glaucoma Due to Posterior Synechiae of Iris Following Combined Phacoemulsification and 23-Gauge Transconjunctival Vitrectomy.

Purpose: To describe the clinical characteristics of eyes with secondary angle-closure glaucoma following combined phacovitrectomy.

Methods: Retrospective case series.

Results: Nine eyes developed angle-closure glaucoma due to iris posterior synechiae with an incidence rate of 1.

Retinal Neovascularisation in Susac Syndrome: A Rare Complication.

Purpose: To report a case of Susac syndrome with ocular complications in the chronic stage of the disease.

Methods: Case report.

Results: A 37-year-old male patient of Indian origin presented with painless blurring of vision in the right eye.

Clinical outcomes of double membrane peeling with or without simultaneous phacoemulsification/gas tamponade for vitreoretinal-interface-associated (VRI) disorders.

The purpose of this study is to evaluate the clinical outcomes of double membrane (ERM & ILM) peeling and the effect of combined cataract surgery and SF6 gas injection in vitreoretinal interface (VRI) disorders. This is a retrospective interventional study. Seventy-two eyes with idiopathic vitreoretinal interface abnormalities that underwent 23 gauge pars plana vitrectomy with "double stain and double peel" technique were reviewed.

Ocular manifestations in hyperornithinemia-hyperammonemia-homocitrullinuria syndrome: a rare association.

Purpose: To report ophthalmic features in hyperornithinemia-hyperammonemia-homocitrullinuria syndrome, an uncommon presentation.

Methods: Case report.

Results: An 18-year-old Indian boy presented with progressive diminution of vision, night blindness, lenticular opacities, and midperipheral chorioretinal atrophy.
