Pediatric vitreoretinal surgery (PVRS) has important differences compared to that in adults. The main indications for PVRS include rhegmatogenous retinal detachments (RRD) caused by trauma, congenital retinoschisis, Marfan, Stickler or morning-glory syndrome, peripheral retinal degenerations, fundus coloboma, retinoblastoma, myopia, previous ocular surgery and tractional retinal detachments (TRD) caused by retinopathy of prematurity (ROP), persistent fetal vasculature (PFV), familial exudative vitreoretinopathy (FEVR) and penetrating ocular trauma. RRD in the adult usually associates with the posterior vitreous detachment (PVD), while as the RRD in pediatric age is often caused by trauma or congenital abnormalities. As pediatric retinal detachments (RD) usually present in late stages and pediatric ocular anatomy is featured, PVRS is more difficult and complex and has greater complication rates. The most common and devastating complication of PVRS is proliferative vitreoretinopathy (PVR). In particular, creating an iatrogenic retinal break (IRB) during PVRS can cause PVR in children because of the strong inflammatory and proliferative response.1−5

Glaucoma is the commonest pattern of optic neuropathy characterized as a gradual loss of retinal ganglion cells (RGCs) as well as classic modifications to the retinal nerve fiber layer (RNFL) and optic nerve.1 Depending on the angle appearance at gonioscopy, it is classified as open-angle or closed-angle glaucoma.1 Likewise, if an underlying cause is established, the disease is perceived as secondary glaucoma.1 Considering closed-angle glaucoma characteristics, secondary drug-induced is a rare disease with a huge potential of perpetual visual loss.1

To date, consent for complex ocular procedures has not received much attention in the literature. As a specialty, ophthalmology surrenders to the ‘treadmill’ efficiency of pooled lists, assigned assessments and generic patient information sheets.7 There is an assumption that valid consent has been gained when patients may still be uninformed. Furthermore, patients may report high levels of satisfaction, yet remain to have poor levels of understanding.8 Patient retention of operation risks is poor and the capacity to provide fully informed consent is influenced by the patients level of education, literacy and language competency.9–11 The anatomy of the lacrimal system and potential for surgery is a difficult concept for patients to perceive, especially without pictorial or comprehensive written material devoid of medical jargon. Considering all these factors, it may be likely that the process we deem as valid consent is actually an uninformed one. To our knowledge no prior studies have looked at objective improvement in patient recollection and understanding during informed consent for dacryocystorhinostomy (DCR). In our survey, we aimed to evaluate the effectiveness of our current standard consenting process for dacryocystorhinostomy (DCR) at increasing understanding and comprehension in a competent patient in a specialist ophthalmology centre in London.

Glaucoma is a chronic disease necessitating a lifelong treatment in order to prevent the occurrence of irreversible blindness.1 Glaucoma is the second leading cause of blindness in Nigeria2 and the leading cause of irreversible blindness globally.3 The primary objective of glaucoma therapy is to prevent progressive vision loss and blindness. Lowering of intraocular pressure (IOP) is the only proven strategy that prevents the risk of glaucoma progression.4,5 Medical therapy, laser procedures, and incisional surgical treatment are reasonable options for the initial treatment of glaucoma (lowering intraocular pressure) and most patients initially receive topical ocular hypotensive drops.6 In the majority of cases topical therapy is beneficial if administered correctly. Poor patient adherence to chronic medical therapy has been well documented across the disease spectrum over the past several decades.6−8 Non adherences to medical treatments by glaucoma patients may lead to resultant visual impairment, blindness, and disabilities. Therefore, the outcome of therapy relies heavily on patient adherence to the treatment regimen.7 Successful outcomes of medical treatment for glaucoma requires proper and daily use of medication to prevent disease progression. According to the World Health Organization (WHO), adherence to long-term therapies among patients suffering from chronic diseases in the general population is around 50% and is much lower in developing countries.8 Nonadherence among glaucoma patients has been reported to range as high as 80%.9 Patients with poor adherence to medication have worse outcomes with a higher rate of visual loss and increase health care costs.10 Adherence is defined as the degree to which a patient follows the instructions to take a prescribed treatment during a defined period of time.11

Looking back not many years ago, the significant change in how the patient used to be cared for compared to the current days is undeniable. Starting from surgical techniques and the machines we use, moving to how we now manage long-term conditions that were nearly impossible to be managed in the most optimistic ophthalmologist’s mind back in the days. For example, mind-blowing innovations and great efforts are now dedicated to controlling conditions causing significant sight impairment such as AMD or retinitis pigmentosa. Living in the current era where technology and innovations dominate and influence our lives, remarkable, unprecedented advances are taking place. As expected, tiny, well-designed and connected instruments and the accompanying apps make it possible to undertake eye examinations anywhere in the world – making patients the point of care. Internationally, this considerable step would provide ophthalmic service to people in unprivileged areas and people in war zones. Using smartphones and newly built lenses might be the future of out of hospital ophthalmology. One can imagine how using these remote approached would provide a quicker response to some of the most serious ophthalmic emergencies where time is vital in determining the future of the patients’ vision and the quality of their life. For instance, it is not imaginary being able to diagnose retinal artery occlusion or an acute angle closure glaucoma using criteria that does not require the patient to waste valuable time in A&Es. We have all heard about a watch being able to detect a fall or a life-threatening arrhythmia, not far from today, we might see devices and implants to identify ocular emergencies that significantly reduce the long-term complications of not having responded to an ophthalmic emergency in a timely manner.1,2

Congenital nasolacrimal duct obstruction is a condition that occurs commonly in infants22-25 and usually resolves with conservative management alone24-20. It is the most common cause of epiphora in infants1,2 70% of neonates present with congenital nasolacrimal duct obstructions at delivery3 with only 6-20% being symptomatic4,5 as the obstruction usually resolves before lacrimal secretion begins.6 The common approach in the management of this condition is lacrimal massage and observation with or without topical antibiotic treatment as most cases of nasolacrimal duct obstruction resolve without surgery.7−11 Another option is an immediate office probing approach with topical anaesthesia and restraint and this was not found to be superior to observation and massage.12 The assessment of pediatric epiphora involves looking for a high tear meniscus, recurrent mucopurulent discharge and applying pressure to the lacrimal sac contents by pressure to reflex the contents.6,13 Other conditions which may present with epiphora need to be excluded including epiblepharon, congenital entropion, congenital glaucoma, keratitis and uveitis.5 The fluorescent dye disappearance test is a non invasive test that can confirm nasolacrimal duct obstruction with 90% sensitivity8. Down’s syndrome and craniofacial malformations may be associated with a higher prevalence of congenital nasolacrimal duct obstruction which can be confirmed with imaging.9

According to Gass Retinal Pigment Epithelial Hamartoma (RPEH) is a presumed congenital pigment epithelial adenomas or primary pigment epithelial hyperplasia.1 RPEH is a non-hereditary benign retinal tumour of unknown aetiology, possibly due to translocation between the short arms of chromosomes 11 and 18, like Combined Hamartoma of the Retina and Retinal Pigment Epithelium.2 Congenital simple Hamartoma of Retinal Pigment Epithelium (CSHRPE) was first recognized in 1981 by Laqua3 and later characterized and named in 1989 by Gass, who reported ten cases.1 In 2003, Shields documented the largest subsequent case series, consisting of five patients.4 CSHRPE is a rare intraocular finding that is described as a unilateral, focal, nodular, jet black lesion. That frequently occur at or near the macula, no known association with changes in the surrounding neurosensory retina, RPE or choroid, nor have they been related with exudation or hemorrhage . Usually, involves the full thickness of the retina through the I.L.M. (Internal Limiting Membrane) with an umbrella shaped in the inner retinal surface.1 The patients are asymptomatic, and usually have normal visual acuity. For this reason though these lesions are congenital, they often are not identified until adulthood. Although, sometimes children may develop amblyopia and strabismus due to macular involvement.
