This chapter describes anaesthesia for paediatric ophthalmic cases. Management is generally straightforward, but is not without its problems and complications. Most procedures are day cases, but they may involve children who are unable to comply with tests when awake, children having multiple procedures, or syndromes associated with their ophthalmic condition. Ages range from the neonate to teenagers and involve procedures such as examination under anaesthesia (EUA), squint surgery, cataract surgery (and its complications), nasolacrimal surgery, oculoplastic surgery, and glaucoma surgery. The side effects of ocular drops are discussed, as are the risks of surgery in and around the eye, e.g. the oculocardiac reflex. Also covered are emergencies such as ‘the penetrating eye injury’ scenario.

Potential Factor

Intraocular foreign bodies are a potential factor threatening with loss of vision. The development of cataract and symptoms of ocular siderosis are the most common signs of ferrous metal entering the eye. We present a case of a 45-year-old man who reported to the hospital for planned cataract surgery. He denied the possibility of any past eye injury. Despite this, apart from the cataract, X-ray and CT scans confirmed the presence of an intralenticular foreign body and symptoms of ocular siderosis. Cataract surgery was successfully performed using phacoemulsification, and the metallic foreign body was removed. Intraocular foreign body symptoms may be overlooked by patients and even physicians and may occur with considerable delay. Hence, in patients with indirect symptoms of penetrating eye injury, the presence of an intraocular foreign body should not be ruled out, even if the patient denies this possibility.

Purpose. To assess the severity of penetrating eye trauma in children in Tajikistan. Material and methods. Retrospectively there was analyzed 277 case histories of children with a diagnosis of penetrating eye injury, admitted to the children’s department of the National Medical Centre of the Republic of Tajikistan for the provision of specialized ophthalmological care. Results. The average age of children at the time of injury to the organ of sight was 7.06 ± 3.01 years, mainly these were villagers (70%). Children under 7 years old accounted for 57.8% of those admitted to the hospital. The terms of admission to the hospital ranged from 1 to 14 days, an average of 43.02 ± 33.35 hours. The severity is caused by damage to 2 or more structures of the eyeball in 81,3%. Wounds larger than 6 mm prevailed and amounted to 63,5%. Endophthalmitis at admission was noted in 8,3% of cases. Enucleation was performed in 2 children; 244 children underwent primary surgical treatment. Visual acuity at discharge was higher than 0.1 in 72 of 275 children (26.2%), lower than 0,1 in 194 (70.7%). Conclusion. Almost every second child (43.0%) is admitted to the hospital for primary surgical treatment of an eyeball wound after 24 hours. About 2/3 of cases of eye damage are characterized by large wound sizes. Stab wounds were noted in 90.2% of cases. In 58.8% of cases, damage to the cornea was observed and in 68.6% – damage to the lens area.

A Prospective Study

Background: The aim of the study is to investigate whether the circadian IOP rhythm can be influenced by combined cataract surgery with high frequency deep sclerotomy (HFDS) and whether intraocular pressure (IOP) can be significantly reduced by HFDS. Methods: In our study 10 patients were included, in whom 24 h IOP monitoring was installed before and after HFDS/cataract surgery using a Triggerfish. HFDS is a minimally invasive glaucoma surgery (MIGS). Results: After performed HFDS combined with cataract surgery, the IOP was reduced from 27.7 ± 2.11 mmHg to 14.4 ± 2.59 mmHg, which is highly significant (p < 0.001). The contact lens sensor (CLS) cosinor analysis pre- and postoperatively showed that the circadian rhythm is not influenced by the surgery, i.e., the circadian IOP rhythm did not show significant differences before and after surgery. Conclusions: HFDS combined with cataract surgery is a potent surgical method that can significantly reduce the IOP. However, the circadian rhythm cannot be changed by the surgery. The acrophase remained during the night in all patients.

Corneal Endothelial Cell Density

ObjectiveWe aim to systematically assess and compare corneal endothelial cell density (ECD) loss in patients with glaucoma following glaucoma surgery and cataract surgery.IntroductionCorneal ECD loss may occur due to intraoperative surgical trauma in glaucoma surgery or postoperatively with chronic endothelial cell trauma or irritation. Corneal oedema and decompensation after aqueous shunt glaucoma surgery has been reported but the long-term ECD loss is still unknown.Inclusion criteriaTrabeculectomy, glaucoma filtration surgery or microinvasive glaucoma surgery in adults with ocular hypertension, primary and secondary open angle glaucoma, normal tension glaucoma and angle-closure glaucoma. Participants with pre-existing corneal disease will be excluded. Glaucoma laser treatments and peripheral iridotomy will be excluded. The outcomes include preoperative and postoperative corneal ECD, percentage change of corneal ECD and adverse events.MethodsWe will conduct an electronic database search for randomised controlled trials, prospective non-randomised studies, observational studies in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov and The International Prospective Register of Systematic Reviews (PROSPERO). Eligibility criteria will include quantitative articles published after and including the year 2000, written in English and containing data on ECD loss. Two independent reviewers will screen titles and abstracts and extract data from full texts, reporting outcomes according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data extraction of key characteristics will be completed using customised forms. Methodological quality will be assessed using the Joanna Briggs Institute critical appraisal forms.Ethics and disseminationEthics approval is not required for this review, as it will only include published data. Findings will be published in a peer-reviewed journal and disseminated across ophthalmic networks.PROSPERO registration numberPROSPERO CRD42020192303.

Abstract Minimally invasive glaucoma surgery (MIGS) has fulfilled an unmet need in the management of glaucoma. This chapter highlights some controversial issues regarding the use of MIGS in clinical practice, including (1) whether there is sufficient evidence to advocate combining MIGS with cataract surgery over cataract surgery alone, (2) the merits and drawbacks of different approaches to trabecular bypass and canal-based MIGS procedures, (3) the effect of MIGS on endothelial cell loss, (4) suprachoroidal MIGS devices and whether there is still a role for these procedures, and (5) a comparison between subconjunctival MIGS and trabeculectomy. Several questions are still left unanswered and hopefully, further research and more clinical experience with these new technologies will help improve surgical outcomes for patients.
