Traumatic subhyaloid macular hemorrhage with complete resolution following Neodymium-Doped Yttrium Aluminium Garnet Laser.

ABSTRACT: Purpose:To report a case of traumatic subhyaloid macular hemorrhage with severe sudden vision loss treated successfully with Neodymium-Doped Yttrium Aluminium Garnet Laser (Nd:YAG laser). Observations:A 16-year-old boy presented to the eye clinic with acute vision loss secondary to blunt trauma by a stone to his left eye 3 days prior to consultation that caused subhyaloid macular hemorrhage. Nd:YAG laser was performed to open the hyaloid membrane and allow the blood to diffuse into the vitreous cavity and be absorbed. The patient demonstrated complete recovery as his visual acuity went from counting fingers to 20/20 within 20 days. No complications due to the treatment were reported. Conclusions and importance:To the best of our knowledge, there have been no reported cases of subhyaloid macular hemorrhage treated with Nd:YAG laser in which the etiology was trauma and showed full, rapid recovery with no sequelae.

Project description:INTRODUCTION:A current non-pharmacological mean for attaining painless conservative treatment is presented by laser analgesia (LA), considered as bio-photomodulation of pulp reactivity aiming reduction of nociceptive impulse formation. Currently no consensus is reached regarding a detailed protocol with laser parameter settings for pre-emptive LA. The purpose of this study is determining the efficacy of erbium-doped yttrium aluminium garnet (Er:YAG) laser in achieving pulpal analgesia and quantifying duration and extent of any effects assessed. METHODS AND ANALYSIS:The proposed study is a double-blind placebo-controlled randomized split-mouth clinical trial with 2-way repeated measures design. Eligible patients of age 10 to 12 years undergo 2 single-visit treatments, receiving LA or placebo analgesia (PA) prior to caries ablation, randomized via computer-generated, permuted-block sequence. Primary outcome measure is pain felt during treatment, reported by patient on visual-analogue scale. SECONDARY OUTCOMES:changes in pulpal sensibility to electrical and cold-stimuli; patient experience during LA/PA; pain-related behavior according to Faces, Legs, Activity, Cry, Consolabilty (FLACC) scale; heart-rate dynamics. Data will be analyzed with intention-to-treat concept by Student t test for paired samples, P?<?.05. Pre-test on 20 subjects resulted in n?=?41 patients needing to be recruited. ETHICS AND DISSEMINATION:This study protocol has been approved by the Committee for Scientific Research Ethics, Medical University - Plovdiv, Bulgaria (Reference number P-8604, Protocol of approval N:6/23.11.2017) and registered on a publically accessible database. This research received institutional funding from the Medical University - Plovdiv, Bulgaria under project SPD-03/2017. Findings will be reported in scientific publications and at research conferences, and in project summary papers for participants. TRIAL REGISTRATION:ClinicalTrials.gov (Registration number: NCT03412721).
