Temporary keratoprostheses in anterior and posterior segment surgery: A narrative review of their history and development
Visualizing the posterior segment during vitreoretinal surgery can be difficult in eyes with concurrent corneal opacity. Temporary keratoprostheses have emerged as devices that ensure visibility of the posterior vitreous cavity while simultaneously preserving the donor corneal graft. Several models of these devices are described in the current literature, and new design models and surgical techniques surrounding their use continue to be developed. We summarize the different temporary keratoprosthesis models with their associated surgical techniques, advantages, and shortcomings; discuss the clinical results of studies util...

Efficacy of Ahmed and Baerveldt glaucoma drainage device implantation in the pediatric population: A systematic review and meta-analysis
Glaucoma drainage devices (GDD) are increasingly utilized in the management of childhood glaucoma. This systematic review and meta-analysis assesses the efficacy of first-time Ahmed or Baerveldt implantation in children. PubMed, Embase, and Cochrane Library were searched for relevant English-language, peer-reviewed literature. Postoperative outcomes were pooled using random effects regression models with restricted maximum likelihood estimation. Thirty-two studies (1221 eyes, 885 children) were included.

Effects of Systemic Drugs on the Development and Progression of Age-Related Macular Degeneration
Age-related macular degeneration (AMD) affects central vision and leads to a substantial loss of visual acuity. AMD involves mainly the central area of the retina. It may lead to an impairment of central vision and difficulty with dark adaptation via degenerative effects on the paracentral and more peripheral retina besides the central macula. The risk of AMD increases with age and is the leading cause of vision loss in the United States in people over the age of 60.[63,70] The pathophysiology of this disease is multifactorial: a combination of genetic, aging, inflammatory, and environmental factors.

Typical and atypical clinical presentations of X-Linked retinoschisis: A case series and literature review
X-linked retinoschisis (XLRS) is an X-linked inherited retinal dystrophy characterized by mild-to-severe visual impairment, splitting of the retinal layers, and a reduction in the dark-adapted b-wave amplitude on the electroretinogram. Typical clinical features include macular and peripheral schisis. Relatively common features reported include rhegmatogenous or tractional retinal detachment, vitreous hemorrhage, retinal pigment epithelial changes, vitreous veils, and various retinal vascular abnormalities with or without exudation.

Stepwise approach for fundus imaging in the diagnosis and management of posterior uveitis
An array of retinochoroid imaging modalities aid in comprehensive evaluation of the immunopathological changes in the retina and choroid, forming the core component for the diagnosis and management of inflammatory disorders such as uveitis. The recent technological breakthroughs have led to the development of imaging platforms that can evaluate the layers of retina and choroid and the structural and functional alteration in these tissues. Ophthalmologists heavily rely on imaging modalities such as dye-based angiographies such as fluorescein angiography and indocyanine green angiography, optical coherence tomography, fundus...

Vitelliform maculopathy: Diverse etiologies originating from one common pathway
Vitelliform lesions (VLs) are associated with a wide array of macular disorders but are the result of one common pathway: retinal pigment epithelium (RPE) impairment and phagocytic dysfunction. VLs are defined by the accumulation of yellowish subretinal material. In the era of multimodal advanced retinal imaging, VLs can be further characterized by subretinal hyper-reflectivity with optical coherence tomography and hyperautofluorescence with fundus autofluorescence. VLs can be the result of genetic or acquired retinal diseases. (Source: Survey of Ophthalmology)

Comment on: Retinal displacement following rhegmatogenous retinal detachment: A systematic review and meta-analysis
Gross retinal reattachment is a rough measure of successful surgery for rhegmatogenous retinal detachment. With the improvement of instruments, techniques and observation systems in recent years, retinal reattachment rates have also increased.1,2 To date, however, few attempts have been made to compare the alignment and structural integrity of retinal reattachment between different procedures and techniques.

Update on the systemic management of non-infectious uveitis in children and adolescents
Pediatric uveitis is a rare but treatable cause of visual impairment in children. Approximately 60% of children with uveitis will have associated systemic disease, most commonly rheumatological,35 and therefore thorough investigation is required in a child without a prior diagnosis. The most common type of uveitis seen in children is juvenile idiopathic arthritis-associated uveitis(JIA-U), often picked up on screening of an asymptomatic child.44 In this paper, we will use the term pediatric to refer to children and adolescents up to 18 years old.

Amblyopia: A review of unmet needs, current treatment options, and emerging therapies
Amblyopia is a global public health issue with extensive, multifaceted impacts on vision and quality of life (QoL) for both patients and families. Geographical variation exists in the management of amblyopia, with traditional mainstay treatments, optical correction, and fellow eye occlusion most successful when implemented at an early age. In recent years, however, studies demonstrating meaningful improvements in older children and adults have challenged the concept of a complete loss of visual processing plasticity beyond the critical period of visual development, with growing evidence supporting the potential efficacy of...

Orbital and ocular perfusion in thyroid eye disease
Thyroid eye disease (TED) also termed Graves orbitopathy, is a common accompaniment of Graves ’ disease (GD), with a reported prevalence being 40 % (confidence interval: 0.30 to 0.48)34. Visual acuity decline in TED may occur as a consequence of tear film abnormalities, optic neuropathy, exposure keratopathy, corneal ulceration, chorioretinal folds, or transient obscurations due to orbital congestion53. Subtle involvement of the optic nerve (ON) may go unnoticed unless looked for specifically 100 and result in permanent visual impairment in 4 to 8% of TED cases from dysthyroid optic neuropathy (DON)14,114.

The natural history of untreated ocular hypertension and glaucoma
Glaucoma is a chronic, progressive disease leading to irreversible blindness if left untreated; however, since reducing intraocular pressure has proven to be successful in slowing disease progression, little is known about the natural history of untreated glaucoma. This knowledge can be valuable in guiding management decisions in the era of personalized medicine. A systematic search was performed in Medline (PubMed), Embase, and Web of Science in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRIMSA) guidelines.
