Purpose: To describe a series of sight-threatening ocular and adnexal involvement associated with dengue hemorrhagic fever and their treatment options. Methods: Retrospective, interventional, non-comparative case series. Medical records of patients who presented with ocular symptoms attributed to dengue hemorrhagic fever were reviewed. Demography, presenting features, and treatment outcomes were recorded. Outcome measures assessed included globe salvage, vision salvage, and visual improvement. The outcome was deemed as favorable if vision salvage was possible and unfavorable if the vision was

Purpose: The aim of the present study was to compare the effects of the preoperative doses of betamethasone acetate 0.1% and placebo on controlling dry eye after cataract surgery. Methods: This randomized triple-blind clinical trial was conducted on 62 patients. For the purpose of the study, the participants were assigned into two groups of betamethasone (n = 28) and placebo (n = 34). The groups were administered with drops A or B three days before the operation, four times a day. These drops contained either betamethasone 0.1% or normal saline (placebo).

Purpose: To investigate if the accuracy of intraocular pressure (IOP) measurements using rebound tonometry over disposable hydrogel (etafilcon A) contact lenses (CL) is affected by the positive power of the CLs. Methods: The experimental group comprised 26 subjects, (8 male, 18 female). IOP measurements were undertaken on the subjects’ right eyes in random order using a Rebound Tonometer (ICare). The CLs had powers of +2.00 D and +6.00 D. Measurements were taken over each contact lens and also before and after the CLs had been worn.

A 22-year-old female patient was diagnosed to have HIV and treated by highly active antiretroviral therapy (HAART) since 2012 had developed a reduction of vision in both eyes secondary to cataract. The cataract was extracted from both eyes with no immediate postoperative complication. During follow-up, it was recognized that she had had bilateral Stage 3 macular hole in both eyes. The visual acuity in both eyes was 6/60 which did not improve with application of pinhole. Pars plana vitrectomy was done and sealed the macular hole in the left eye. The visual acuity remained the same in both eyes
